Disclosure of basis of consolidation [text block]	2) BASIS OF PRESENTATION OF THE CONSOLIDATED FINANCIAL STATEMENTS a) Statement of compliance with IFRS and basis of preparation The consolidated financial statements were prepared in accordance with International Financial Reporting Standards (“IFRS”) issued by the International Accounting Standard Board (“IASB”) prevailing at December 31, 2017 . The consolidated financial statements have been prepared on a historical costs basis, with th e exception of derivative financial instruments and financial liability related to the option for acquisition of non-controlling interest , which have been measured at fair value. The consolidated financial statements have been approved by the Board of Dir ectors ( the “ Board ”) and Audit Committee of the Company, Atento S.A. in Luxembourg on April 19 , 201 8 . These consolidated financial statements have not been yet approved by the General Shareholders Meeting of the Parent Company. However, the Board of Direct ors expects them to be approved without amendments. The preparation of financial statements under IFRS as issued by the IASB requires the use of certain key accounting estimates. IFRS also requires Management to exercise judgment throughout the process of applying the Atento Grou p’s accounting policies. Note 3r discloses the areas requiring a more significant degree of judgment or complexity and the areas where assumptions and estimates are more relevant to the consolidated financial statements. Also, Note 3 contains a detailed description of the most significant accounting policies used to prepare these consolidated financial statements. The amounts in these consolidated financial statements, comprising the consolidated statements of financial position, th e consolidated statement s of operations , the consolidated statements of comprehensive income /(loss) , the consolidated statements of changes in equity, the consolidated statements of cash flow s , and the notes thereto are expressed in thousands of U.S. dolla rs, unless otherwise indicated. b) Comparative information The main changes are: On September 2, 2016, the Company through it s direct subsidiar y Atento Brasil acquired 81, 49 %, the controlling interest of RBrasil Soluções S.A. (RBrasil) and on September 30, 2016 the Company through its direct subsidiary Atento Teleservicios España sold 100 % of Atento M o rocco. In accordance with IFRS 5 the results of the operations in Morocco are presented in consolidated statements of operations as discon tinued operations for the year s ended December 31, 2016 and 2015. On June 9, 2017, the Company, through its subsidiary Atento Brasil, acquired control of Interfile Serviços de BPO Ltda. and of Interservicer – Serviços em Crédito Imobiliário Ltda. (jointly , “Interfile”), a leading provider of BPO services and solutions, including credit origination, for the banking and financial services sector in Brazil. Through this acquisition, the Company expect s to be able to expand the capabilities in the financial se rvices sector , especially in credit origination, accelerate the penetration into higher value-added solutions, strengthen the leadership position in the Brazilian market and facilitate the expansion of the credit origination sector into other Latin America n markets. See more details of this acquisition in Note 5. c) Consolidated statement s of cash flow s The consolidated statement s of cash flow s has been prepared using the indirect method pursuant to IAS 7 , “Statement of Cash Flow”. Foreign currency transactions are translated at the average exchange rate for the period, in those cases where the currency differs from the presentation currency of Atento Group (U.S. dollar), as indicated in Note 3 c . The effect of exchange rate fluctuations on cash and cash equivalents, maintained or owed, in foreign currency, is presented in the statement s of cash flow s to reconcile cash and cash equivalents at the beginning of the year and at year-end .

Disclosure of objectives, policies and processes for managing capital [abstract]
Disclosure of changes in accounting policies, accounting estimates and errors [text block]	3) ACCOUNTING POLICIES The main accounting policies used to prepare the accompanying consolidated financia l statements are set out below. a) Principles of consolidation, business combinations and goodwill (i ) Subsidiaries Subsidiaries are all entities (including structured entities) over which the Atento Group has control. The Atento Group controls an entity when the Atento Group is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power to direct the activities of the entity. Subsidiaries are fully consolidated from the date on which control is obtained by the G roup , until the Group loses control of the entity . Intercompany transactions, balances and unrealized gains on transactions between the Atento Group companies are eliminated on consolidation, except those arisen from exchange variations. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the transferred asset. Accounting policies of subsidiaries have been changed where necessary to ensure consistency with the policies adopted by the Atento Group. Non-controlling interests in the results and equity of subsidiaries are show n separately in the consolidated statements of operations, statement of comprehensive income/(loss), statement of changes in equity and financial position, respectively. (ii) B usiness combinations a nd goodwill The Atento Group applies the acquisition method to account for business combinations. The consideration transferred for the acquisition of a subsidiary is the fair value of the assets acquired, the liabilities assumed vis-à-vis the former owners of the acquire, and any equity instruments therein issued by the Atento Group. The consideration transferred includes the fair value of any asset or liability resulting from any contingent consideration. Any contingent consideration to be transferred by the Atento Group is r ecognized at its fair value as of the acquisition date. Subsequent changes in the fair value of any contingent consideration deemed an asset or a liability are recognized in the statements of operations or as a change in other comprehensive income/(loss), in accordance with IAS 39, “Financial Instruments: Recognition and Measurement”. Contingent consideration classified as equity is not remeasured, and any subsequent settlement thereof is also recognized in equity. Costs related to the acquisition are recog nized as expenses in the year in which they are incurred. Identifiable assets acquired and identifiable liabilities and contingent liabilities assumed in a business combination are initially measured at fair value as of the acquisition date. Goodwill is initially measured as any excess of the total consideration paid over the net identifiable assets acquired and liabilities assumed. If the fair value of the net assets acquired is greater than the aggregate consideration transferred, the difference is reco gnized in the statements of operations as a gain or bargain purchase. Goodwill acquired in a business combination is allocated to each cash -generating unit, or group of cash- generating units, that are expected to benefit from the synergies arising in the business combination. Goodwill is tested for impairment annually or whrenever if there are certain events or changes in circumstances indicating potential impairment. The carrying amount of the assets allocated to each cash-generating unit is then compare d with its recoverable amount, which is the greater of its value in use or fair value less costs to sell. Any impairment loss is immediately taken to the statements of operations, and may not be reversed (see Note 3h). b) Functional and presentation cur rency Items included in the financial statements of each of the Atento G roup’s entities are measured using the currency of the primary economic environment in which the entities operate (‘the functional currency’). The consolidated financial statements are presented in thousands of U.S. dollars, which is the presentation currency of the Atento Group. c) oreign currency translation The results and financial position of all Atento Group entities whose functional currency is different from the presentation currency are translated into the presentation currency as follow: • Statement s of financial position assets and liabilities are translated at the exchange rate prevailing at the reporting date . • S tatement s of operations items are translated at average exchange rates for the year (unless this average is not a reasonable approximation of the cumulative effect of the rates prevailing on the transaction dates, in which case income and expenses are translated at the rate on t he dates of the transactions) . • Proceeds and payments shown on the statement s of cash flow s are translated at the average exchange rates for the period (unless t his average is not a reasonable approximation of the cumulative effect of the rates prevailing on the transaction dates, in which case income and expenses are translated at the rate on the da tes of the transactions. • Retained earnings are translated at historical exchange rates . • All resulting exchange differences are recognized in other comprehe nsive income /(loss). Goodwill and fair value adjustments to net assets arising from the acquisition of a foreign company are considered to be assets and liabilities of the foreign company and are translated at year­end exchange rates. Exchange differences arising are recognized in other comprehensive income/(loss). d) F oreign currency transactions Transactions in foreign currency are translated into the functional currency using the exchange rates prevailing at the date of the transactions or valuation dat e, in the case of items being remeasured. Foreign exchange gains and losses resulting from the settlement of these transactions and from the translation at reporting date exchange rates of monetary assets and liabilities denominated in foreign currencies a re recognized in the statements of operations, except when deferred in other comprehensive income/(loss). All differences arising on non–trading activities are taken to other operating income/expense in the statements of operations, with the exception of the effective portion of the differences on cash flows and net investment hedge that are accounted for as an effective hedge against a net investment in a foreign entity. These differences are recognised in other comprehensive income/(loss) (OCI) until the hedge settlement and disposal of the net investment, at which time, they are recognised in the statements of operations. Tax charges and credits attributable to exchange differences on those monetary items are also recorded in OCI. Non–monetary items tha t are measured at historical cost in a foreign currency are translated using the exchange rates as at the date of recognition. e) S egment information Segment information is p resented in accordance with management information reviewed by the C hief Operating D ecision M aker (“CODM”) . The CODM , responsible for allocating resources and assessing performance of operational segments, has been identified as the Chief Executive Officer (“CEO”) responsible for strategic decisions. The CODM considers the bus iness from a geographical perspective and analyzes it across three operational segm ents—EMEA, Americas and Brazil. f) I ntangible assets Intangible assets are stated at acquisition cost, less any accumulated amortization and any accumulated impairment loss es. The intangible assets acquired in a business combination are initially measured at their fair value as of the acquisition date. The useful lives of intangible assets are assessed on a case­by­case basis to be either finite or indefinite. Intangible a ssets with finite lives are amortized on a straight line basis over their estimated useful life and assessed for impairment whenever events or changes indicate that their carrying amount may not be recoverable. Intangible assets that have an indefin ite use ful life are not subject to amortization and are tested annually for impairment. The amortization charge on intangible assets is recog nized in the consolidated statement s of operations under “ Amortization”. Amortization methods and useful lives are revise d annually at the end of each reporting period and, where appropriate, adjusted prospectively. Customer bases Customer bases acquired in a business combination are recognised at fair value at the acquisition date and have finite useful lives and are subsequently carried at cost less accumulated amortization, which has been estimated to be between seven and twelve years. The customer bases relate to all agreements, tacit or explicit, entered into between the Atento Group and the former owner of the Atento Group and between the Atento Group and other customers, in relation to the provision of services, and that were acquired as part of the business combinations indicated in Note 5 . Software Software is measured at cost (at acquisition or development costs) and amortized on a straight line basis over its useful life, generally estimated to be between three and five years. Maintenance cost of software is expensed as incurred. Development costs directly attributable to the design and creation of software that are identifiable and unique, and that may be controlled by the Group, are recognized as an intangible asset pr oviding the following conditions are met: • It is technically feasible for the intangible asset to be completed so that it will be available for use or sale. • Management intends to complete the asset for use or sale. • The Group has the capacity to use or sell the asset. • It is possible to show evidence of how the intangible asset will generate probable future economic benefits. • Adequate technical, financial and other resources are available to complete the development and to us e or sell the intangible asset. • The outlay attributable to the intangible asset during its development can be reliably determined. Directly attributable costs capitalized in the value of the software include the cost of personnel developing the programs and an approp riate percentage of overheads. Costs that do not meet the criteria listed above are recognized as an expense as incurred. Expenditure for an intangible asset that is initially recognized within expenses for the period may not be subsequently recognized as intangible assets. Other intangible assets Other intangible assets mainly include payment of loyalty incentives which are amortized on a straight line basis over the term of the agreements which range from four to ten years. g) P roperty, plant and equipment Property, plant and equipment are measured at cost, less accumulated depreciation and any impairment losses. Land is not depreciated. Acquisition costs include, whe n appropriate, the initial estimates of decommissioning, withdrawal and site rec onditioning costs when the Atento Group is obliged to bear this expenditure as a condition of using the assets. Repairs that do not prolong the useful life of the assets and maintenance costs are recognized directly in the statement s of operations . Costs t hat prolong or improve the life of the asset are capitalized as an increase in the cost of the asset. Property, plant and equipment acquired in a business combination are initially measured at fair value as of the acquisition date. The Atento Group asses ses the need to write down, if appropriate, the carrying amount of each item of property, plant and equipment to its period-end recoverable amount whenever there are indications that the assets’ carrying amount may not be fully recoverable through the gene ration of sufficient future revenue. The impairment allowance is reversed if the factors giving rise to the impairment cease to exist. The depreciation charge for items of property, plant and equipment is recognized in the consolidated statement s of opera tions under “Depreciation”. Depreciation is calculated on a straight line basis over the useful life of the asset applying individual rates to each type of asset, which are reviewed at th e end of each reporting period. The useful lives generally used by the Atento Group are as follow: Years of useful life Buildings 5 - 40 Plant and machinery 3 - 6 Furniture, tools 1 - 10 Other tangible assets 5 - 8 Name Registered address Line of business % interest Holding company Atento Luxco Midco, S.à.r.l.

At December 31, 2015 , 2016 and 2017 , none of the Group’s subsidiaries is listed on a stock exchange , except for Atento Luxco 1 S.A. , which has debt securities listed in the International Stock Exchange (TISE) in Guernsey. A ll subsidiaries use year - end Dece mber 31 as their reporting date . t) New and amended standards adopted by the Group The Group has applied the following standards and amendments for the first time for thei r annual reporting period commencing on or after January 1, 2017: Recognition of Deferred Tax Assets for Unrealised Losses – Amendments to IAS 12 ; and Disclosure Initiative – Amendments to IAS 7 . The adoption of these amendments did not have any materia l impact on the current period or any prior period and is not likely to affect future periods. u) New standards and interpretations not yet adopted Certain new accounting standards and interpretations have been published that are not mandatory for December 31, 2017 reporting periods and have not been early adopted by the Group. The G roup’s assessment of the impact of these new standards and interpretations is set out below: Title of standard IFRS 9 Financial Instruments Nature of change IFRS 9 addresses the classification, measurement and recognition of financial assets and financial liabilities, introduces new rules for hedge accounting and a new impairment model for financial assets. Impact The Group has reviewed its financial assets and liabilities and is expecting the following impact from the adoption of the new standard on January 1, 2018: Financial assets The Company’s loans and receivables as per IAS 39 that are held to collect contractual cas h flows that solely represent payments and interest satisfy the conditions for classification as at amortized cost for IFRS 9 and hence there will be no change to the accounting for these assets. We also expect no changes for derivatives, that as per IAS 39 are classified at fair value through profit or loss (unless they are designated as hedges) and would appear to be classified as FVPL as per IFRS 9. Accordingly, the Atento Group does not expect the new guidance to have a significant impact on the cla ssification and measurement of its financial assets. Financial liabilities There will be no impact on the Atento Group’s accounting for financial liabilities, as the new requirements only affect the accounting for financial liabilities that are designat ed at fair value through profit or loss and the Atento Group does not have such liabilities other than derivatives, that as per IAS 39 are classified at fair value through profit or loss (unless they are designated as hedges) and will be classified as FVPL (fair value through profit or loss) as per IFRS 9. The derecognition rules have been transferred from IAS 39 Financial Instruments: Recognition and Measurement and have not been changed. The new hedge accounting rules will align the accounting for hedgi ng instruments more closely with the Atento Group’s risk management practices. As a general rule, more hedge relationships might be eligible for hedge accounting, as the standard introduces a more principles-based approach. The Atento Group’s current hedge relationships will qualify as continuing hedges upon the adoption of IFRS 9. Accordingly, the Atento Group does not expect a significant impact on the accounting for its hedging relationships. The new impairment model requires the recognition of impairment provisions based on expected credit losses (ECL) rather than only incurred credit losses as is the case under IAS 39. It applies to financial assets classified at amortized cost, debt instruments measured at FVOCI (fair value through other compr ehensive income), contract assets under IFRS 15 Revenue from Contracts with Customers, lease receivables, loan commitments and certain financial guarantee contracts. Management does not expect a significant increase in the credit losses, as well as losses on investments held at amortized cost. The new standard also introduces expanded disclosure requirements and changes in presentation. These are expected to change the nature and extent of the Atento Group’s disclosures about its financial instruments part icularly in 2018. Mandatory application date/ Date of adoption by the Group Must be applied for financial years commencing on or after January 1, 2018. The Group will apply the new rules retrospectively from January 1, 2018, with the practical expedi ents permitted under the standard. Comparatives for 2017 will not be restated. Title of standard IFRS 15 Revenue from Contracts with Customers Nature of change The IASB has issued a new standard for the recognition of revenue. This will replace IAS 18 which covers contracts for goods and services and IAS 11 which covers construction contracts. The new standard is based on the principle that revenue is recognised when control of a good or service transfers to a cus tomer. Impact Management has assessed the effects of applying the new standard on the Atento Group’s financial statements and has identified the following services that are likely to be affected: Accounting for certain costs incurred in fulfilling a contract – certain costs which are currently expensed may need to be recognised as an asset under IFRS 15. Variable consideration – IFRS 15 establishes that the Atento Group includes in the transaction price of services the amount of variable considerati on estimated only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur. Some contracts with customer may be impacted for this requirement due to the existence of clauses containing serv ice level requirements, trade discounts, penalties or volume rebates. This could result in different amounts being recognized and/or delay the recognition of a portion of the revenue. Presentation disclosure - IFRS 15 provides presentation and disclosure requirements, which are more detailed than under current IFRS. The presentation requirements represent a significant change from current practice and significantly increases the volume of disclosures required in Atento Group’s financial statements. Many of the disclosure requirements in IFRS 15 are completely new. The Atento Group is reassessing its systems, internal controls, policies and procedures necessary to collect and disclose the required information. The Atento’s Group continue to evaluate custom er contracts to determine the estimated variable consideration as disclosed above. Based on the assessment conducted in 2017, the Company and its subsidiaries do not foresee a significant impact through the adoption of IFRS 15. Mandatory application date/ Date of adoption by the Group The Group intends to adopt the standard using the modified retrospective approach as of January 1, 2018 and the comparatives will not be restated. Title of standard IFRS 16 Leases Nature of change IFRS 16 was issued in January 2016. It will result in almost all leases being recognised on the balance sheet, as the distinction between operating and finance leases is removed. Under the new standard, an asset (the right to use the leased item) and a financial liability to pay rentals are recognised. The only exceptions are short-term and l ow-value leases. The accounting for lessors will not significantly change. Impact The standard will affect primarily the accounting for the Atento Group’s operating leases. As at the reporting date, the Atento Group has operating lease commitments of 240,113 thousand U.S. dollars. However, the Atento Group has not yet determined to what extent these commitments will result in the recognition of an asset and a liability for future payments and how this will affect the Atento Group’s profit and classification of cash flows. Some of the commitments may be covered by the exception for short-term and low-value leases and some commitments may relate to arrangements that will not qualify as leases under IFRS 16. Mandatory applica tion date/ Date of adoption by group Mandatory for financial years commencing on or after January 1, 2019. At this stage, the Atento Group does not intend to adopt the standard before its effective date. Title of standard IFRS 2 Classification and Measurement of Share-based Payment Transactions — Amendments to IFRS 2 Key requirements The IASB issued amendments to IFRS 2 Share-based Payment that address three main areas: the effects of vesting conditions on the measurement of a cash-settled s hare-based payment transaction; the classification of a share-based payment transaction with net settlement features for withholding tax obligations; and accounting where a modification to the terms and conditions of a share-based payment transaction ch anges its classification from cash settled to equity settled. Mandatory application date/ Date of adoption by group On adoption, entities are required to apply the amendments without restating prior periods, but retrospective application is permitted i f elected for all three amendments and other criteria are met. The amendments are effective for annual periods beginning on or after January 1, 2018, with early application permitted. Expected date of adoption by t he Atento Group is January 1, 2018 . Title of standard IFRIC Interpretation 22 Foreign Currency Transactions and Advance Consideration Key requirements The Interpretation clarifies that, in determining the spot exchange rate to use on initial recognition of the related asset, expense or income (or part of it) on the derecognition of a non-monetary asset or non-monetary liability relating to advance consideration, the date of the transaction is the date on which an entity initially recognises the non-monetary asset or non-monetary liabilit y arising from the advance consideration. If there are multiple payments or receipts in advance, then the entity must determine the transaction date for each payment or receipt of advance consideration. Entities may apply the amendments on a fully retrospe ctive basis. Mandatory application date/ Date of adoption by group Alternatively, an entity may apply the Interpretation prospectively to all assets, expenses and income in its scope that are initially recognised on or after: (i) The beginning of the reporting period in which the entity first applies the interpretation ; or (ii) The beginning of a prior reporting period presented as comparative information in the financial statements of the reporting period in which the entity first applies the interpr etation. The Interpretation is effective for annual periods beginning on or after January 1, 2018. Early application of interpretation is permitted and must be disclosed. Expected date of adoption by t he Atento Group is January 1, 2018. Title of standard IFRIC Interpretation 23 Uncertainty over Income Tax Treatment Key requirements The Interpretation addresses the accounting for income taxes when tax treatments involve uncertainty that affects the application of IAS 12 and does not apply to taxes or levies outside the scope of IAS 12, nor does it specifically include requirements relating to interest and penalties associated with uncertain tax treatments. The Interpretation specifically addresses the following: Whether an entity co nsiders uncertain tax treatments separately ; The assumptions an entity makes about the examination of tax treatments by taxation authorities ; How an entity determines taxable profit (tax loss), tax bases, unused tax losses, unused tax credits and tax rates ; How an entity considers changes in facts and circumstances. Mandatory application date/ Date of adoption by group An entity must determine whether to consider each uncertain tax treatment separately or together with one or more other uncertain tax treatments. The approach that better predicts the resolution of the uncertainty should be followed. The interpretation is effective for annual reporting periods beginning on or after January 1, 2019, but certain transition reliefs are available. The G roup will apply interpretation from its effective date. h) Impairment of non­current assets The Atento Group assesses as of each reporting date whether there is an indicator that a non­current asset may be impaired. If any such indicator exists, or when annual impairment testing for an asset is required (e.g. goodwill), the Atento Group estimates the asset’s recoverable amount . An asset’s recoverable amount is the higher of its fair value less costs to sell or its value in use. In assessing the value in use, the estimated future cash flow is discounted to its present value using a pre­tax discount rate that reflects current mar ket assessments of the time value of money and the risks specific to the asset. Where the carrying amount of an asset exceeds its recoverable amount, the asset is considered to be impaired. In this case, the carrying amount is written down to its recoverab le amount, and the resulting loss is recognized in the statement s of operations . Future depreciation/amortization charges are adjusted to reflect the asset’s new carrying amount over its remaining useful life. Management analyzes the impairment of each ass et individually, except in the case of assets that generate cash flow which are interdependent on those generated by other assets (cash generating units – “CGU” ). The Atento Group bases the calculation of impairment on the business plans of the various ca sh generating units to which the assets are allocated. These business plans cover five years. A long-term growth rate is calculated and applied to project future cash flows after the fifth year. When there are new events or changes in circumstances that i ndicate that a previously recognized impairment loss no longer exists or has been decreased, a new estimate of the asset’s recoverable amount is made. A previously recognized impairment loss is reversed only if there has been a change in the estimates used to determine the asset’s recoverable amount since the last impairment loss was recognized. If that is the case, the carrying amount of the asset is increased to its recoverable amount. The reversal is limited to the carrying amount that would have been de termined had no impairment loss been recognized for the asset in prior years. This reversal is recognized in the statement s of operations and the depreciation charge is adjusted in future periods to reflect the asset’s revised carrying amount. Impairment l osses relating to goodwill cannot be reversed in future periods. i) Financial assets and liabilities Financial assets Upon initial recognition, the Atento Group classifies its financial assets into one of four categories: financial assets at fair value through profit or loss, loans and receivables, held­to­maturity investments and available­for­sale financial assets. Thes e classifications are reviewed at the end of each reporting period and modified if appropriate . The Atento Group has classified all of its financial assets as loans and receivables, except for derivative financial instruments. All purchases and sales of financial assets are recognized on the statement of financial position on the transaction date, i.e. when the commitment is made to purchase or sell the asset. A financial asset is fully or partially derecognized from the statement of financial position o nl

Disclosure of financial risk management [text block]	4) MANAGEMENT OF FINANCIAL RISK 4.1 Financial risk factors The Atento Group’s activities are expose d to various types of financial risk: market risk (including foreign currency risk and interest rate risk ) , credit risk and liquidity risk. The Atento Group’s global risk management policy aims to minimize the potential adverse effects of these risks on the Atento Group’s financial returns. The Atento Group also uses derivative financial instruments to hedge certain risk exposures. a) Market ris k Interest rate risk in respect of cash flow and fair value Interest rate risk arises mainly as a result of changes in interest rates which affect: finance costs of debt bearing interest at variable rates (or short-term maturity debt expected to be renewed ), as a result of fluctuations in interest rates, and the value of non­current liabilities that bear interest at fixed rates. Atento Group’s finance costs are exposed to fl uctuations in interest rates. As of December 31, 2017 , 12.8 % of Atento Group’s finance costs are exposed to fluctuations in interest rates( excluding the effect of financial derivative instruments), compared to 40 .6 % as of December 31, 2016 . The Atento Group’s policy is to monitor the exposure to interest at ris k. A s described in Note 1 4 , the Atento Group has entered to interest rate swaps that have the economic effect of converting floating­rate borrowing s into fixed interest rate borrowings . As of December 31, 2017 , the estimated fair value of the in terest rate hedging instruments related to the Br azilian Debentures totaled 1,212 thousand U.S. dollars (1,3 3 0 thousand U.S. dollars financial asset as of December 31, 2016 ), which was recorded as a financial liability . Based on the total indebtedness of 486,291 thousand U.S. dollars as of December 31, 2017 and not taking into account the impact of the interest rate hedging instruments referred to above, a 1% change in interest rates would impact our net interest expense by 1,648 thousand U.S. dollars ( 2,35 3 thousand U.S. dollars as of December 31, 2016 ). The table below shows the impact of a +/­10 basis points variation in the CDI interest rate curves on these derivatives . Thousands of U.S. dollars INTEREST RATE 2017 FAIR VALUE (1,212) 0.10% (1,174) -0.10% (1,248) Foreign currency risk Our foreign currency risk arises from local currency revenues, receivables and payables, while the U.S. dollar is our functional and reporting currency. We benefit to a certain degree from the fact that the revenue we collect in each country, in which we have operations, is generally denominated in the same currency as the majority of the expenses we incur. In accordance with our risk management policy, whenever we deem it appropriate, we manage foreign currency risk by using deri vatives to hedge any exposure incurred in currencies other than those of the functional currency of the subsidiary . . Upon issuance of the Senior Secured Notes due 2022 denominated in U.S. dollars, we entered into new cross-currency swaps pursuant to which we exchanged an amount of U.S. dollars for an amount of Euro, Mexican Pesos, Peruvian Soles and Brazilian Reais . The table below shows the impact of a +/­10 basis points variation in the interest rate curve on the value of the cross-currency swaps . Thousands of U.S. dollars CROSS-CURRENCY 2017 FAIR VALUE 3,037 0.10% 2,718 -0.10% 3,838 As of December 31, 2017 , the estimated fair value of the cross-currency swaps de signated as hedging instrument s totaled an asset of 3,037 thousand U.S. dollars (asset of 75, 960 thousand U.S. dollars as of December 31, 2016 ) . 2016 Financial assets (*) Financial liabilities (*) Sensitivity analysis Functional currency - financial asset/liability currency Functional currency (thousands) Asset currency (thousands) U.S. Dollar (thousands) Functional currency (thousands) Liability currency (thousands) U.S. Dollar (thousands) Appreciation of asset/liability currency vs functional currency Appreciation of financial assets in functional currency Statements of operations (thousands of U.S. dollar) Appreciation of financial liabilities in functional currency Statements of operations (thousands of U.S. dollar) Euro - Colombian Pesos 244 817,344 272 - - - 10% 2,846.7435699 287 45 - - Euro - Dirham Moroccan 252 2,848 281 - - - 10% 9.6064349 297 47 - - Euro - Peruvian Nuevos Soles 64 241 72 - - - 10% 3.1838036 76 12 - - Euro - USD 3,515 3,705 3,705 - - - 10% 0.9486900 3,905 412 - - Chilean Pesos – USD 212 - - - - - 10% 0.0013487 235 - - - Mexican Pesos – USD 6 - - - - - 10% 0.0436482 - - - - Brazilian Reais – USD 6 2 2 - - - 10% 0.2761499 7 - - - Guatemalan Quetzal – USD 2,442 325 325 - - - 10% 0.1196470 2,713 36 - - Colombian Pesos – USD 590,271 197 197 - - - 10% 0.0002999 655,857 22 - - Peruvian Nuevos Soles - USD 23,484 6,998 6,998 5,138 1,531 1,531 10% 0.2681764 26,094 778 5,709 (170) United States Dolar - Euro 11,068 10,500 11,068 - - - 10% 0.8538089 12,298 1,230 - - United States Dolar - MXN 79 1,627 79 - - - 10% 18.5574600 88 9 - - Chilean Pesos – Euro 292 - - - - - 10% 0.0012795 324 - - - (*) Financial liabilities correspond to borrowing in currencies other than functional currencies.

Financial assets correspond to cash and cash equivalents in currencies other than functional currencies. b) Credit risk The Atento Group seeks to conduct all of its business with reputable national and international companies and institutions established in their countries of origin, to minimize credit risk. As a result of this policy, the Atent o Group has no material adjustments to make to its credit accounts (see Note 1 3 ). Accordingly, the Atento Group’s commercial credit risk management approach is based on continuous monitoring of the risks assumed and the financial resources necessary to manage the Group’s various units, in order to optimize the risk­reward relationship in the development and implementation of business plans in the course of their regular business. Credit risk arising from cash and cash equivalents is managed by placing cash surpluses in high quality and highly liquid money- market assets. These placements are regulated by a master agreement revised annually on the basis of the conditions prevailing in the markets and the countries where Atento operat es. The master agreement establishes: (i) the maximum amounts to be invested per counterparty, based on their ratings (long - and short - term debt ratings); (ii) the maximum period of the investment; and (iii) the instruments in which the surpluses may be in vested. The Atento Group’s maximum exposure to credit risk is primarily limited to the carrying amounts of its financial assets (see Notes 11 to 15 ). The Atento Group holds no guarantees as collection insurance. As disclosed in Note 2 3 , the Atento Group c arries out significant transactions with the Telefónica Group, which represents 39.2 % in 2017 and 33.7 % in 2016 . c) Liquidity risk The Atento Group seeks to match its debt maturity schedule to its capacity to generate cash flow s to meet the payments falling due, factoring in a degree of cushion. In practice, this has meant that the Atento Group’s average debt maturity must be longer enough to support business operation normal conditions (assuming that internal projections are met ). A maturity schedule for the Atento Group’s financial liabilities is provided in Note 1 6 . 4.2 Capital Management The Atento Group’s Finance Department, which is in charge of the capital management, takes various factors into consideration when determining the Group’s capital structure. The Atento Group’s capital management goal is to determine the financial resources necessary both to continue its recurring activities and to maintain a capital structure that optimizes own and borrowed funds. The Atento Group sets an optimal debt level in order to maintain a flexible and comfortable medium - term borrowing structure, in order to be able to carry out its routine activities under normal conditions and to address new opportunities for growth. Debt levels are kept in line with forecast ed future cash flow s and with quantitative restrictions imposed under financing contracts. As indicated in N ote 17, a mong the restrictions imposed under financing arrangements, the debenture contract lays out certain general obligations and disclosures in respect of the len ding institutions, s pecifically , Atento Brasil S.A. must comply with the quarterly net financial debt/EBITDA ratio set out in the contract terms. In addition to these general guidelines, we take into account other considerations and specifics when determi ning our finan cial structure, such as country risk , tax efficiency and volatility in cash flow generation. The contract also sets out additional restrictions, including limitations on dividends, payments and distributions to shareholders and capacity to incur additional debt. The Super Senior Revolving Credit Facility, described in Note 17, carries no financial covenant obligations regarding debt levels. However, the notes do impose limitations on the distributions on dividends, payments or distributions to the shareholders, the incurring of additional debt, and on investments and disposal of assets. As of the date of these consolidated financial statements, the Atento Group was in compliance with all restrictions established in the aforementioned financ ing contracts, and does not foresee any futur e non- compliance. To that end, the Atento Group regularly monitors figures for net financial debt with third parties and EBITDA. Net financial debt with third parties at December 31, 2016 and 2017 is as follow: Thousands of U.S. dollars 2016 2017 Senior Secured Notes (Note 17) 303,350 398,346 Brazilian bonds - Debentures (Note 17) 156,596 21,055 Bank borrowings (Note 17) 71,353 56,392 Finance lease payables (Note 17) 3,636 10,498 Less: Cash and cash equivalents (Note 15) (194,035) (141,762) Net financial debt with third parties 340,900 344,529 Fair value estimation a) Level 1: The fair value of financial instruments traded on active markets is based on the quoted market price at the reporting date. b) L evel 2: The fair value of financial instruments not traded in active market (i.e. OTC derivatives) is determined using valuation techniques. Valuation techniques maximize the use of available observable market data, and place as little reliance as possible on specific company estimates. If all of the significant inputs required to calculate the fair va lue of a financial instrument are observable, the instrument is classified in Level 2. The Atento Group’s Level 2 financial instruments comprise interest rate swaps used to hedge floating rate loans and cross-curr ency swaps. c ) Level 3: If one or more signif icant inputs are not based on observable market data, the instrument is classified in Level 3. The Atento Group’s assets and liabilities measured at fair value as of December 31, 2016 and 2017 are classified in Level 2 . No t ransfers were carried out between the different levels during the period. The assets measured at fair value are the derivative financial instruments. The liabilities measured at fair value are the derivative financial instruments and the options for acquisitions of NCI.

The acquisition transaction costs totaling 890 thousand Brazilian Reais ( 273 thousand U.S. dollars) were recognized in the statements of operations . Since the acquisition date, RBrasil contributed to the Company with revenues of 5,951 thousand U.S. dollars and pre-tax profit of 858 thousand U.S. dollars. If the acquisition had occu rred on January 1, 2016, the contribution of net revenues an d pre-tax result in the Company ’ s consolidate d financial statements for the year ended December 31, 2016, would amount 18,392 and (2,254) thousand U.S. dollars, respectively. Guarantees The amount equivalent to 9,400 Brazilian Reais ( 2,884 thousand U.S. dollars) of the consideration transferred to the sellers tha t no longer are shareholders of RBrasil was transferred to an escrow account in order to guarantee payment for any loss that is indemnifiable by them. The guarantee of the payment of any pot ential loss identifiable by the sellers who continue being minority shareholders of RBrasil to the Company pledged their rig hts to all dividends, interest i n own capital, incomes, distributions, salaries, bonuses, remuneration, capital reimbursement and any other amounts that may come to be credited, paid, distributed or otherwise delivered, for any reason, by RBrasil to these shareholde rs. Put/Call options As per the Shareholders' Agreement, the Company has a purchase option, where non-controlling shareholders irrevocably and irreversibly grant to the Company, through that instrument, the right, but not the obligation, at the sole discre tion of the Company, to acquire all of their shares, and the non-controlling shareholders, through the exercise of that right, shall be obliged to sell their shares to the Company ("call option"). The call option may be exercised by any controlling shareho lder between January 1, 2019 and December 31, 2020. The Shareholders' Agreement also provides for a put option, where the non-controlling shareholders have the right, irrevocable and irreversible, but not the obligation, to sell all of their shares to the Company ("put option"). The put option may be exercised by non-controlling shareholders between January 1, 2019 and December 31, 2020. The exercise price of the call option will be determined by multiples, already defined in the Shareholders' Agreement, of the EBITDA of the year immediately prior to the exercise of the option, multiplied by the percentage of participation to be acquired. IFRS 3 does not provide specific guidance on how such contracts should be accounted for in a business combination. To det ermine the appropriate accounting treatment, IAS 39 - financial Instruments: recognition and measurement and IAS 32- financial instruments: presentation, were considered. On the basis of the above, the Company recognized a financial liability related to th e potential for acquisition of non-controlling interest for an amount of 3,444 Brazilian Reais ( 1,057 thousand U.S. dollars). The financial liability was recognized against specific reserve in shareholders' equity, considering that these are transactions b etween shareholders. b) Nova Interfile Holding Ltda On June 9, 2017, the Company through its indirect subsidiary Atento Brasil S.A. acquired the control and 50,00002% of Interfile Serviços de BPO Ltda. and 50,00002% of Interservicer – Serviços em Crédito Imobiliário Ltda, (“Interfile”) leading providers of BPO services and solutions, including credit origination, for the banking and financial services sector in Brazil. The total amount paid for this acquisition was 14, 664 thousand U.S. dollars, net of cash acquired. Valuations were carried out to measure the preliminary fair value of assets acquired and liabilities assumed for the allocation of the acquisition price, in accordance with the r equirements of IFRS 3 in this interim consolidated financial statements. The preliminary goodwill recognized in the transaction represents expected future synergies of the business combinations and will be deductible for income tax when the acquired entiti es are merged into the Atento Brasil S.A. These benefits are not recognized separately from goodwill because they do not meet the criteria for recognition of identifiable intangible assets. Details of the preliminary purchase p rice allocation of the fair v alues of Interfile and Intersevice , the net assets acquired a nd liabilities assumed are as follows: Thousands of U.S. dollars Assets Cash and cash equivalents 315 Accounts receivable 2,273 Escrow account 2,884 Deferred taxes assets 2,079 Other credits 679 Property, plant and equipment 491 Intangibles (b) 2,628 Liabilities Other obligations (2,932) Provisions for legal proceedings and contingent liabilities (13,105) Total net liabilities assumed at fair value (4,688) Non-controlling interest measured at fair value 928 Goodwill on acquisition 15,214 Total of the consideration 11,454 Purchase price consideration Consideration paid 8,953 Contingent consideration 2,501 Total consideration 11,454 Analysis of the cash flow of the acquisition Consideration paid 8,953 Net cash acquired (315) Outflow cash, net (a) 8,638 Presented as investing activities in the statement of cash flows. Intangible assets acquired which meet the criteria for recognition comprise customer relationships , software database and a non-compete agreement ( classified as other intangible assets in Note 6) identified as part of the purchase price allocation . The fair value amount for accounts receivables is 5,463 thousand U.S. dollars. The gross contractual amount for trade receivables due 5, 643 thousand U.S. dollars . Transaction costs totaling 1 92 thousand U.S. dolla rs are recorded in the statement s of operations . From the date of acquisition, Nova Interfile contributed to the C ompany with net revenues of 22 , 472 thousand U.S. dollars and pre- tax result of 3 ,6 82 thousand U.S. dollars . If the acquisition had occurred on January 1, 2017, the contribution of net revenues and pre-tax result in the C ompany’s consolidated financial statements for the year ended December 31, 2017 , would amount 38,558 and (332) thousand U.S. dollars , respectively . Put/Call options As per the Shareholders' Agreement, the Company has a purchase option, whe re non-controlling shareholders grant ed to Atento Brasil S.A. , through that instrument, the right, to acquire all of their shares, and the non-controlling shareholders, through the exercise of that right, shall be obliged to sell their shares to Atento Brasil S.A. ("call option"). The call option may be exercised by Atento Brasil S.A. between January 1, 2020 and April 15 , 2020. The Shareholders ' Agreement also provides for put option s , where the non-controlling shareholders have the right, to sell partial or all of their shares to the Atento Brasil S.A. ("put option s "). Many put options were understood b y M anagement as protective clauses with remote possibility of being exercised. The assessment of the put options were made taking into account the following; (i) probability of occurrence; (ii) degree of importance (primary or secondary, in this case as te rm extension or acceleration of other options) and (iii) function: effective options or clauses protecting the parties. Considering the valuation of the acquired entity and M anagement ’s best estimates, the put option that will likely to be exercised by the non-controlling shareholders is between January 1, 2020 and April 15, 2020 – which is symmetrical with the call option. According to IAS 32, a parent must recognize a financial liability when it has an obligation to pay cash in the future to purchase the minority’s shares, even if the payment is conditional on the option being exercised by the holder. The exercise price of the put option will be determined by multiples, already defined in the Shareholders' Agreement, of the EBITDA of the year immediately p rior to the exercise of the option, multiplied by the percentage of participation to be acquired. IFRS 3 does not provide specific guidance on how such contracts should be accounted for in a business combination. To determine the appropriate accounting tre atment, IAS 39 - Financial Instruments: Recognition and M easurement, IAS 32- Financial Instruments: Presentation and IFRS 10 – Consolidated Financial S tatements were considered. On the basis of the above, the Company recognized a financial liability relate d to the potential acquisition of non-controlling interest of 23,777 thousand U.S. dollars . The financial liability was recogni zed against specific reserve in equity, considering that these are transactions between shareholders. 5) BUSINESS COMBINATIONS a) RBrasil Soluções S.A. On September 2, 2016, the Company through its in direct subsidiar y Atento Brasil S.A. acquired the control and 81.49 %, of the shares of RBrasil Soluções S.A. (“RBrasil”), a leading provider of late-stage collection services in Brazil. The total amount paid for this acquisition was 27,095 thousand Brazilian Reais (8,638 thousand U.S. dollars), net of cash acquired. The Purchase and Sale Agreement also included a contingent consideration that can vary from zero to 8,150 thousand Brazilian Reais (2,501 thousand U.S. dollars), according to the result of the operation, which will be measured through RBrasil's EBITDA. Therefore, based on projections the Company also recorded a contingent consideration of 8,150 t housand Brazilian Reais (2,501 thousand U.S. dollars), representing its fair value as of the acquisition date. As a result, the total consideration transferred to 36,273 thousand Brazilian Reais (11,130 thousand U.S. dollars). Valuations were carried out t o measure the fair value of intangible assets and liabilities and allocation of the acquisition price, in accordance with the requirements specified in IFRS 3. The goodwill recognized in the transaction represent future benefits of the expected synergies i n the business combinations and will be income tax deductible when RBrasil is merged into the Company. These benefits are not recognized separately from the goodwill because they do not meet the criteria for recognition of identifiable intangible assets. T he fair value in U.S.dollars of identifiable assets acquired and liabilities assumed of RBrasil on the date of acquisition is as follows:

Disclosure of impairment loss and reversal of impairment loss [abstract]
Disclosure of impairment of assets [text block]	8 ) IMPAIRMENT OF ASSETS As of December 31, 2017 , the impairment assessment on goodwill performed by the Atento Group’s management indicated that the carrying amount of goodwill is recoverable. Such assessment was based on the calculation of the recoverable amount of goodwill through the calculation of t he expected future cash flow from the cash­generating units to which goodwill is allocated . Atento has no other assets with indefinite useful lives, and therefore carries out no impairment tests of this type. The Atento Group carries out its goodwill impai rmen t tests using the various cash-generating units’ five - year strategic plans and budgets, approved by Management. Recoverable amount is based on value in use calculated using cash flow from projected results adjusted for amortization/depreciation, finan ce costs, and taxes, based on the last period, and using the expected growth rates obtained from studies published in the sector and assuming said growth to be constant from the fifth year. Estimated cash flow determined in this manner is discounted using the WACC applicable to that CGU. The discount rates used reflect the current assessment of specific ma rket risks in each of the cash- generating units, considering the time value of money and individual country risks not included in the cash flow estimates. WACC takes both the cost of debt and capital into account. The latter is obtained based on the return expected by the shareholders of the Atento Group, while the former is obtained based on the Atento Group’s finance costs. In addition, the risks specific to each country were included in the WACC using corrective factors. These tests are performed annually and whenever it is considered that the recoverable amount of goodwill may be impaired. At December 31, 2016 and 2017 , the tes ts conducted did not reveal any impairment in the value of goodwill, since the related recoverable amounts calculated using value in use were in all cases higher than the carrying amount of the related cash - generating units, even after sensitivities were applied to the variables used. The pre - tax discount rates, which factor in country and business risks, and the projected growth rates were as follow: Discount rate Brazil Mexico Spain Colombia Peru Chile December 2016 13.99% 10.18% 8.43% 12.25% 11.02% 10.91% December 2017 12.74% 12.09% 10.62% 12.48% 11.54% 11.35% Growth rate Brazil Mexico Spain Colombia Peru Chile December 2016 4.70% 3.50% 2.10% 3.70% 4.20% 3.00% December 2017 3.85% 4.00% 1.60% 3.40% 2.50% 2.40% The recoverable amounts per country were as follow: Thousand U.S. dollars Recoverable amounts Brazil (*) Mexico Colombia Peru Chile Argentina December 2017 879,303 25,400 59,643 226,881 60,607 90,143 (*) The total recoverable amount of is composed by 33,618 thousand U.S. dollars from the acquisition of RBrasil, 140,373 thousand U.S. dollars from the acquisition of Interfile and 705,312 thousand from Atento Brasil. In the event of a 10% increase or decrease in the discount rate used to calculate the recoverable amount of the CGUs in each country, with the other variables remaining unchanged, the recoverable amount would still be higher than the corresponding carrying amount. Management also considers that the appearance of potential competitors in the market in which the Atento Group operates could negatively affect the growth of its CGUs. In addition, if as a result of a fall in demand or an increase in costs , results before amortization/depreciation, finance cost and taxes margin (EBITDA margin) used for estimating cash flow were to keep constant for the five years in each country, with all other variables remaining unchanged, the recoverable amount from each cash generating unit would continue to be higher than its corresponding carrying amount. In addition to the above, specifically for certain countries, the following assumptions were used: Cas h flow for the Brazil, Mexico , Spain, Colombia, Peru Chile and A rgentina CGUs were estimated based on growth projections considering past business performance, using predicted inflation levels taken from external sources. For calculations regarding the Spanish CGU, negative and positive business forecasts were used whi ch contemplate macroeconomic trends and changes in the environment.

The Super Senior Revolving Credit Facility bears interest at a rate per annum equal to LIBOR or, for borrowings in euro, EURIBOR or, for borrowings in Mexican Pesos, TIIE plus an opening margin of 4.25% p er annum. The margin may be reduced under a margin ratchet to 3.75% per annum by reference to the consolidated senior secured net leverage ratio and the satisfaction of certain other conditions. The terms of the Super Senior Revolving Credit Facility Agree ment limit, among other things, the ability of the Issuer and its restricted subsidiaries to (i) incur additional indebtedness or guarantee indebtedness; (ii) create liens or use assets as security in other transactions; (iii) declare or pay dividends, red eem stock or make other distributions to stockholders; (iv) make investments; (v) merge, amalgamate or consolidate, or sell, transfer, lease or dispose of substantially all of the assets of the Issuer and its restricted subsidiaries; (vi) enter into transa ctions with affiliates; (vii) sell or transfer certain assets; and (viii) agree to certain restrictions on the ability of restricted subsidiaries to make payments to the Issuer and its restricted subsidiaries. These covenants are subject to a number of imp ortant conditions, qualifications, exceptions and limitations that are described in the Super Senior Revolving Credit Facility Agreement. The Super Senior Revolving Credit Facility Agreement includes a financial covenant requiring the drawn super senior le verage ratio not to exceed 0.35:1.00 (the “SSRCF Financial Covenant”). The SSRCF Financial Covenant is calculated as the ratio of consolidated drawn super senior facilities debt to consolidated pro forma EBITDA for the twelve-month period preceding the rel evant quarterly testing date and is tested quarterly on a rolling basis, subject to the Super Senior Revolving Credit Facility being at least 35% drawn (excluding letters of credit (or bank guarantees), ancillary facilities and any related fees or expenses ) on the relevant test date. The SSRCF Financial Covenant only acts as a draw stop to new drawings under the Revolving Credit Facility and, if breached, will not trigger a default or an event of default under the Super Senior Revolving Credit Facility Agre ement. The Issuer has four equity cure rights in respect of the SSRCF Financial Covenant prior to the termination date of the Super Senior Revolving Credit Facility Agreement, and no more than two cure rights may be exercised in any four consecutive financ ial quarters. As of December 31, 2017, we were in compliance with this covenant.

Disclosure of classes of share capital [abstract]
Disclosure of share capital, reserves and other equity interest [text block]	19 ) EQUITY Share capital As of December 31, 2017 , share capital stood at 48 thousand U.S. dollars (€33,304), divided into 73,909,056 shares. PikCo owns 68 . 14 % of ordinary shares of Atento S.A. Share premium The share premium refers to the difference between the subscription price that the shareholders paid for the shares and their nominal value. Since this is a capital reserve, it can only be used to increase capital, offset losses, redeem, reimburse or repurchase shares. Reserve for acquisition of non-controlling interest Refers to options attributable to the parent c ompany in the acquisition of RBrasil and Interfile in the total amount of 23,531 thousand U.S. dollars as of December 31, 2017 and 1,057 thousand of U.S. dollars for acquisition of RBrasil as of December 31, 2016. Dividends On October 31, 2017, our Board of Directors declared a cash interim dividend of 24,147 thousand U.S. dollars with dividends declared p er share of $0.33, paid on November 28, 2017. Legal reserve According to commercial legislation in Luxembourg, Atento S.A. must transfer 5 % of its year pr ofits to legal reserve until the amount reaches 10 % of share capital. The legal reserve cannot be dis tributed. At December 31, 2016 and 2017 , no legal reserve had been established, mainly due to the losses incurred by Atento S.A . Translation differences Translation differences reflect the differences arising on account of exchange rate fluctuations when converting the net assets of fully consolidated foreign companies from local currency into Atento Group’s presentation currency (U.S. dollars). . Stock-based compensation a) Description of share based payment arrangements In 2014, Atento granted the following two share-based payment arrangements to directors, officers and other employees, for the Company and its subsidiaries; 1. Time Restricted Stock Units (“RSU”) (equity settled) • Grant date: December 3, 2014 • Amount: 256,134 RSUs • Vesting period: 50% vests on October 1, 2015 and the remaining 50% vests on October 1, 2016. • There are no other vesting conditions. 2. Performance RSU (equity se ttled) • Grant date: December 3, 2014 • Amount: 931,189 RSUs • Vesting period: 100% of the RSUs vest on October 1, 2017. • Performance based vesting conditions: • TSR Tranche: 50% of the RSUs shall satisfy the performance vesting condition, if at all, base d on the Total Shareholder Return (“TSR”) thresholds set forth, and measured from October 1, 2014 through the end of the financial quarter immediately preceding October 1, 2017; provided, that the baseline price for purposes of measuring the TSR compound a nnual growth will be $15.00. The thresholds are as follow: • Below 10% compound annual growth: nil RSUs vest; • 10% compound annual growth: 25% of the RSUs vest; • 22% compound annual growth: 100% of the RSUs vest; and • Compound annual growth between 10% and 22%: RSUs vest based on a linear relationship • Adjusted EBITDA Tranche: The remaining 50% of the RSUs shall satisfy the performance vesting condition, if at all, based on the Adjusted EBITDA thresholds set forth; provided, that for purposes of measur ing the Adjusted EBITDA Tranche, the Performance Period shall include the time period between end of the financial quarter immediately preceding October 1, 2014 through the end of the financial quarter immediately preceding October 1, 2017. The thresholds are as follow: • Below 8% compound annual growth: nil RSUs vest; • 8% compound annual growth: 25% of the RSUs vest; • 13.5% compound annual growth: 100% of the RSUs vest; and • Compound annual growth between 8% and 13.5%: RSUs vest based on a linear relationship. The TSR Tranche and the Adjusted EBITDA Tranche are treated separately. Thus, for example, even if the TSR threshold is not met, provided the Adjusted EBITDA threshold is met, PRSUs will vest. On July 1, 2016, Atento granted the following share-based payment arrangement to directors, officers and other employees, for the Company and its subsidiaries: 1. Time Restricted Stock Units (“RSU”) (equity settled) • Grant date: July 1, 2016 • Amount: 1,384,982 RSUs • Vestin g period: 100% of the RS Us vest on January 4, 2019 • There are no other vesting conditions On July 3, 2017, Atento granted a new share-based payment arrangement to directors, officers and other employees, for the Company and its subsidiaries: Time Restricted Stock Units (“RSU”) (equity settled) • Grant date: July 3, 2017 • Amount: 886,187 RSUs • Vestin g period: 100% of the RSUs vest on January 2, 2020 • There are no other vesting conditions b) Measurement of fair value The fair value of the RSUs, for all arrangement s, has been measured using the Black­Scholes model. For all arrangements are equity settled and the fair value of RSUs is measured at grant date and not remeasured subsequently . The inputs used in the measurement of the fair values at the grant date are pres ented here below. The 2014 Plan: Time RSU Performance RSU Time RSU Time RSU Adj.

The Time RSU has been split into two options for valuation purposes to reflect correctly the fact that 50% of the Time RSUs vests on October 1, 2016 and the remaining 50% will vest on October 1, 2017. The Performance RSU has one market condition which needs to be taken into account when determining the grant date fair value. Two scenarios have been used to determine this fair value. For scenario “TSR 1” a compound annual growth of 10% was used; and for scenario “TSR 2” a compound annual growth rate of 22%. Given the base line price of USD15.00 (which was the opening price when Atento went to the stock exchange), a current stock price of USD 11.06 and a low expected volatility, it is unlikely that the PRS Us of the TSR Tranche will vest. This results in a low valuation. The Adjusted EBITDA Tranche is not included in the fair value condition as this tranche has a non market performance condition. The 2016 Plan: The Time RSU reflects the fact that 100% of the Time RSUs will vest on January 4, 2019. The 2016 Extraordinary Plan:

Atento Brasil S.A. has made payments in escrow related to taxes claims 4,619 thousand U.S. dollars and 4,4 0 7 thousand U.S. dollars as of December 31, 2016 and 2017, respectively. The amount recognized under “Provision for dismantling” corresponds to the necessary cost of dismantling of the installations held under operating leases to bring them to its original condition . As of December 31, 2017 , lawsuits still before the courts as follow: Brazil At December 31 , 2017 , Atento Brasil was involved in approximately 14,750 labor-related disputes ( 12,364 labor disputes as of December 31, 2016 ) , filed by Atento’s employees or ex-employees for various reasons, such as dismissals or claims over employment conditions in general. The total am ount of the main claims classified as possible was 162,701 thousand U.S. dollars ( 134,244 thousand U.S. dollars on December 31, 2016 ). In addition, at December 31, 2017 , there ar e labor-related disputes belonging to the company Atento Brasil 1 (formely Casa Bahia Contact Center Ltda – “CBCC”) totaling 749 thousand U.S. dollars. According to the Company’s external attorneys, materialization of the risk event is p roba ble. M oreover, as of December 31, 2017 , Atento Brasil was party to 14 civil public actions filed by the Labor Prosecutor’s Office due to alleged irregularities mainly concerning daily and general working routine, lack of overtime control and improper hea lth and safety conditions in the workplace. The total amount involved in these claims was approximately 27,870 thousand Brazilian Reais ( 28,132 thousand U.S. dollars ), of which 856 thousand Brazilian Reais relate to claims that have been classified as prob able by our internal and external lawyers, for which amount Atento Bra s il has recorded a provision , as indicated in the paragraph above. We expect that our ultimate liability for these claims, if any, will be substantially less than the full amount claimed . These claims are generally brought with respect t o specific jurisdictions in Braz il, and it is possible that in the future similar claims could be brought against us in additional jurisdictions. We cannot assure that these current claims or future claims brought against us wi ll not result in liability to the Company , and that such liability would not have a material adverse effect on our business, financial condition and results of operations. As of December 31, 2017, Atento Brasil S.A. has 8 civil lawsui ts ongoing for various reasons ( 14 o n December 31, 2016 ) which, according to the Company’s external attorneys, materialization of the risk event is possible. The total amount of the claims is approximately 5,953 thousand U.S. dollars ( 4,948 t housand U.S. dollars on December 31, 2016 ). In addition, at December 31, 2017 , Atento Brasil S.A. has 42 disputes ongoing with the tax authorities and social security authorities, for various reasons relating to infraction procee dings filed (46 on December 31, 2016 ). The total amount of these claims is approximately 59,445 thousand U.S. dollars ( 30,885 thousand U.S. dollars on December 31, 2016 ). According to the Company’s external attorneys, risk of ma terial loss is possible. In addition, as of December 31, 2017 , there are tax authorities disputes belonging to the company CBCC totaling 2,640 thousand U.S. dollars. According to the Company’s external attorneys, materialization of the risk event is p roba ble. Furthermore, it is important to highlight out that the Superior Labor Court of Appeals ( Tribunal Superior do Trabalho ) during the month of August 2015 decided to amend the indexation rate related to labor contingencies. The decision alte rs the Reference Rate I ndex ( TR ) usually used to adjust the amount of the contingencies to th e Special Broad Consumer Price I ndex ( Í ndice de Preços ao Consumidor Amplo Especial – IPCA-E). There are several questions about this matter, especially the period to which change should be applied as well as if the new index is ap propriate. In addition, during October 2015 , the Supreme Court ( STF ) issued a “writ of Mandamus” to the Federation of Brazilian Banks ( FEBRABAN ) suspending the application of the new index ( IPCA-E ). On September 31, 2017, a new decision of the Superior Labor Court of Appeals on the application of the index IPCA-E was amended, changing the initial date of the application of the index from June 30, 2009 to March 25, 2015. As early as December 2017 came the judgment of the Brazilian Bank Federation (FEBRABAN), declaring unfounded the suit proposed by FEBRABAN. With this unfounded, the effects of the injunction that had been granted by the STF were ceased. However, considering that this recent S upreme Court decision was rendered after the entry into force of Law 13,467 / 17 (Labor Reform), the conclusion that can be sustain it is that its effects would be limited to 25 March 2015 to 10 November 2017 because the new law gave a new text to the Arti cle 879 of the Consolidated Labor Laws (CLT), to expressly determine that it will be apply the TR to upgrading of workers' claims arising from criminal conviction. Thus, the Company considered this quarter the new modulation projection of the IPCA-E in la bor, and this, the external opinion of our lawyers also considering as “possible” the probability of loss in an eventual dispute. The amount involved in the period from March 25, 2015 to November 10, 2017 is approximately 755 thousand U.S. dollars. We will monitor this issue during 2018. On December 31, 2017 , the subsidiary RBrasil Soluções S.A. holds contingent liabilities of labor nature classified as possible in the approximate amount of 377 thousand U.S. dollars. On December 31, 2017 , the subsidiary Interfile holds contingent liabilities of labor nature and social charges classified as possible in the approximate amount of 2,297 thousand U.S. dollars . Additionally , there are other contingencies which are classified as pos sible by the Company amounting to 5, 849 thousand U.S. dollars. Spain At December 31, 2017 , Atento Teleservicios España S.A.U. including its branches and our other Spanish companies were party to labor-related disputes filed by Atento employees or former employees for different reasons, such as dismissals and disagreements regarding employment conditions, totaling 3,538 thousand U.S. dollars. According to the Company’s external lawyers, materialization of the risk event is possible. Mexico At D ecember 31, 2017 , Atento Me xico through its two entities (Atento Servicios, S.A. de C.V. and Atento Atencion y Servicios, S.A. de C.V.) is a party of labor related disputes filed by Atento employees that abandoned their employment or former employees that base their claim on justified termination reasons, totaling 7,187 thousand U.S. dollars (Atento Servicios, S.A. de C.V . 4,318 thousand U.S. dollars and Atento Atencion y Servicios, S.A. de C.V. 2,869 thousand U.S. dollars), according to the external labor law firm for possible risk labor disputes. Argentina In Argentina, as a consequence of an unfavourable sentence on the case “ATUSA S.A. ” issued by Argentinian Internal Revenue Services (“ Administración Federal de Ingresos Públicos” ) , notifi ed on February 2017, the risk qualified so far as “remote” becomes now “ possible ” being this contingency est imated amount of approximately 2 , 454 thousand U.S. dollar s at December 31, 2017 (3,147 thousand U.S. dollars on December 31, 2016 ). A formal appeal has been filed at the National Supreme Court of Justice. Given the nature of the risks covered by these provisions, it is not possible to determine a reliable schedule of potential payments, if any.

Disclosure of operating segments [abstract]
Disclosure of operating segments [text block]	2 3 ) SEGMENT INFORMATION The CEO is the C hief Operating D ecision M aker (“CODM”). Management has determined the operati ng segments on the basis of the information reviewed by the CEO for the purposes of allocating resources and a ssessing performance. The results measurement used by the CEO to a ssess the performance of the Atento Group’s segments is the EBITDA and Adju sted EBITDA (as defined below). The CEO considers the business from the geographical pers pective in the following areas: • EMEA, which combines the activities carried out regionally in Spain and Morocco 1 . • The Americas, which includes the activities carried out by the various Spanish-speaking companies in Mexico, Central and South America. It also includes tra nsac tions in the United States. • Brazil, which is managed separately in view of its different language and major importance. Inter-segment transactions ar e carried out at market prices. The Atento Group uses EBITDA and Adjusted EBITDA to track the perfor mance of its segments and to establish operating and strategic targets. Management believes that EBITDA and Adjusted EBITDA provides an important measure of the segment’s operating performance because it allows management to evaluate and compare the segmen ts’ operating results, including their return on capital and operating efficiencies, from period to period by removing the impact of their capital structure (interest expenses), asset bases (depreciation and amort ization), and tax consequences. EBITDA is d efined as profit/(loss) for the period from continuing operations before net finance expense (which includes finance income, finance costs, change in fair value of financial instruments and net foreign exchange losses), income taxes and deprecia tion and amortization. Adjusted EBITDA is defined as EBITDA adjusted to exclude acquisition and integration related costs, restructuring costs, site relocation costs, financing fees, asset impairments and other items which are not related to our core oper ating results. EBITDA and Adjusted EBITDA are a commonly reported measure and are widely used among analysts, investors and other interested parties in the Atento Group’s industry, although not a measure explicitly defined in IFRS, and therefore, may not b e comparable to similar indicators used by other companies.

SUBSEQUENT EVENT In March 2018, Atento Brasil S.A. a indirect subsidiary of Atento S.A. received a tax notice from the Brazilian Federal Revenue Service, related to Corporate Income Tax (IRPJ) and Social Contribution on Net Income (CSLL) for the period from 2012 to 2015, due to the disallowance of the expenses on tax amortization of g oodwill and deductibility of certain financing costs originated of the acquisition of Atento Brasil S.A. by Bain Capital in 2012 , and the withholding taxes on payments made to certain of our former shareholders. The amount of the tax assessment from the Brazilian Federal Revenue Service, not including interest and penalties, was approximately 105, 268 thousand U.S. dollars, and was assessed by the Company’s outside legal counsel as possible loss. We disagree with the proposed tax assessment and we intend to defend our position, which we believe is meritorious, through applicable administrative and, if necessary, judicial remedies. Based on our interpretation of the relevant law, and based on the advice of our legal and tax advisors, we believe the positio n we have taken is sustainable. Consequently, no provisions are recognized regarding these proceedings.

Disclosure of objectives, policies and processes for managing capital [abstract]
Description of accounting policy for principles of consolidation explanatory [text block]	a) Principles of consolidation, business combinations and goodwill (i ) Subsidiaries Subsidiaries are all entities (including structured entities) over which the Atento Group has control. The Atento Group controls an entity when the Atento Group is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power to direct the activities of the entity. Subsidiaries are fully consolidated from the date on which control is obtained by the G roup , until the Group loses control of the entity . Intercompany transactions, balances and unrealized gains on transactions between the Atento Group companies are eliminated on consolidation, except those arisen from exchange variations. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the transferred asset. Accounting policies of subsidiaries have been changed where necessary to ensure consistency with the policies adopted by the Atento Group. Non-controlling interests in the results and equity of subsidiaries are show n separately in the consolidated statements of operations, statement of comprehensive income/(loss), statement of changes in equity and financial position, respectively.
Description of accounting policy for business combinations and goodwill [text block]	(ii) B usiness combinations a nd goodwill The Atento Group applies the acquisition method to account for business combinations. The consideration transferred for the acquisition of a subsidiary is the fair value of the assets acquired, the liabilities assumed vis-à-vis the former owners of the acquire, and any equity instruments therein issued by the Atento Group. The consideration transferred includes the fair value of any asset or liability resulting from any contingent consideration. Any contingent consideration to be transferred by the Atento Group is r ecognized at its fair value as of the acquisition date. Subsequent changes in the fair value of any contingent consideration deemed an asset or a liability are recognized in the statements of operations or as a change in other comprehensive income/(loss), in accordance with IAS 39, “Financial Instruments: Recognition and Measurement”. Contingent consideration classified as equity is not remeasured, and any subsequent settlement thereof is also recognized in equity. Costs related to the acquisition are recog nized as expenses in the year in which they are incurred. Identifiable assets acquired and identifiable liabilities and contingent liabilities assumed in a business combination are initially measured at fair value as of the acquisition date. Goodwill is initially measured as any excess of the total consideration paid over the net identifiable assets acquired and liabilities assumed. If the fair value of the net assets acquired is greater than the aggregate consideration transferred, the difference is reco gnized in the statements of operations as a gain or bargain purchase. Goodwill acquired in a business combination is allocated to each cash -generating unit, or group of cash- generating units, that are expected to benefit from the synergies arising in the business combination. Goodwill is tested for impairment annually or whrenever if there are certain events or changes in circumstances indicating potential impairment. The carrying amount of the assets allocated to each cash-generating unit is then compare d with its recoverable amount, which is the greater of its value in use or fair value less costs to sell. Any impairment loss is immediately taken to the statements of operations, and may not be reversed (see Note 3h).
Description of accounting policy for functional currency [text block]	b) Functional and presentation cur rency Items included in the financial statements of each of the Atento G roup’s entities are measured using the currency of the primary economic environment in which the entities operate (‘the functional currency’). The consolidated financial statements are presented in thousands of U.S. dollars, which is the presentation currency of the Atento Group.
Description of accounting policy for foreign currency translation [text block]	c) oreign currency translation The results and financial position of all Atento Group entities whose functional currency is different from the presentation currency are translated into the presentation currency as follow: • Statement s of financial position assets and liabilities are translated at the exchange rate prevailing at the reporting date . • S tatement s of operations items are translated at average exchange rates for the year (unless this average is not a reasonable approximation of the cumulative effect of the rates prevailing on the transaction dates, in which case income and expenses are translated at the rate on t he dates of the transactions) . • Proceeds and payments shown on the statement s of cash flow s are translated at the average exchange rates for the period (unless t his average is not a reasonable approximation of the cumulative effect of the rates prevailing on the transaction dates, in which case income and expenses are translated at the rate on the da tes of the transactions. • Retained earnings are translated at historical exchange rates . • All resulting exchange differences are recognized in other comprehe nsive income /(loss). Goodwill and fair value adjustments to net assets arising from the acquisition of a foreign company are considered to be assets and liabilities of the foreign company and are translated at year­end exchange rates. Exchange differences arising are recognized in other comprehensive income/(loss). d) F oreign currency transactions Transactions in foreign currency are translated into the functional currency using the exchange rates prevailing at the date of the transactions or valuation dat e, in the case of items being remeasured. Foreign exchange gains and losses resulting from the settlement of these transactions and from the translation at reporting date exchange rates of monetary assets and liabilities denominated in foreign currencies a re recognized in the statements of operations, except when deferred in other comprehensive income/(loss). All differences arising on non–trading activities are taken to other operating income/expense in the statements of operations, with the exception of the effective portion of the differences on cash flows and net investment hedge that are accounted for as an effective hedge against a net investment in a foreign entity. These differences are recognised in other comprehensive income/(loss) (OCI) until the hedge settlement and disposal of the net investment, at which time, they are recognised in the statements of operations. Tax charges and credits attributable to exchange differences on those monetary items are also recorded in OCI. Non–monetary items tha t are measured at historical cost in a foreign currency are translated using the exchange rates as at the date of recognition.
Description of accounting policy for segment reporting [text block]	e) S egment information Segment information is p resented in accordance with management information reviewed by the C hief Operating D ecision M aker (“CODM”) . The CODM , responsible for allocating resources and assessing performance of operational segments, has been identified as the Chief Executive Officer (“CEO”) responsible for strategic decisions. The CODM considers the bus iness from a geographical perspective and analyzes it across three operational segm ents—EMEA, Americas and Brazil.
Description of accounting policy for intangible assets other than goodwill [text block]	f) I ntangible assets Intangible assets are stated at acquisition cost, less any accumulated amortization and any accumulated impairment loss es. The intangible assets acquired in a business combination are initially measured at their fair value as of the acquisition date. The useful lives of intangible assets are assessed on a case­by­case basis to be either finite or indefinite. Intangible a ssets with finite lives are amortized on a straight line basis over their estimated useful life and assessed for impairment whenever events or changes indicate that their carrying amount may not be recoverable. Intangible assets that have an indefin ite use ful life are not subject to amortization and are tested annually for impairment. The amortization charge on intangible assets is recog nized in the consolidated statement s of operations under “ Amortization”. Amortization methods and useful lives are revise d annually at the end of each reporting period and, where appropriate, adjusted prospectively. Customer bases Customer bases acquired in a business combination are recognised at fair value at the acquisition date and have finite useful lives and are subsequently carried at cost less accumulated amortization, which has been estimated to be between seven and twelve years. The customer bases relate to all agreements, tacit or explicit, entered into between the Atento Group and the former owner of the Atento Group and between the Atento Group and other customers, in relation to the provision of services, and that were acquired as part of the business combinations indicated in Note 5 . Software Software is measured at cost (at acquisition or development costs) and amortized on a straight line basis over its useful life, generally estimated to be between three and five years. Maintenance cost of software is expensed as incurred. Development costs directly attributable to the design and creation of software that are identifiable and unique, and that may be controlled by the Group, are recognized as an intangible asset pr oviding the following conditions are met: • It is technically feasible for the intangible asset to be completed so that it will be available for use or sale. • Management intends to complete the asset for use or sale. • The Group has the capacity to use or sell the asset. • It is possible to show evidence of how the intangible asset will generate probable future economic benefits. • Adequate technical, financial and other resources are available to complete the development and to us e or sell the intangible asset. • The outlay attributable to the intangible asset during its development can be reliably determined. Directly attributable costs capitalized in the value of the software include the cost of personnel developing the programs and an approp riate percentage of overheads. Costs that do not meet the criteria listed above are recognized as an expense as incurred. Expenditure for an intangible asset that is initially recognized within expenses for the period may not be subsequently recognized as intangible assets. Other intangible assets Other intangible assets mainly include payment of loyalty incentives which are amortized on a straight line basis over the term of the agreements which range from four to ten years.
Description of accounting policy for property, plant and equipment [text block]	g) P roperty, plant and equipment Property, plant and equipment are measured at cost, less accumulated depreciation and any impairment losses. Land is not depreciated. Acquisition costs include, whe n appropriate, the initial estimates of decommissioning, withdrawal and site rec onditioning costs when the Atento Group is obliged to bear this expenditure as a condition of using the assets. Repairs that do not prolong the useful life of the assets and maintenance costs are recognized directly in the statement s of operations . Costs t hat prolong or improve the life of the asset are capitalized as an increase in the cost of the asset. Property, plant and equipment acquired in a business combination are initially measured at fair value as of the acquisition date. The Atento Group asses ses the need to write down, if appropriate, the carrying amount of each item of property, plant and equipment to its period-end recoverable amount whenever there are indications that the assets’ carrying amount may not be fully recoverable through the gene ration of sufficient future revenue. The impairment allowance is reversed if the factors giving rise to the impairment cease to exist. The depreciation charge for items of property, plant and equipment is recognized in the consolidated statement s of opera tions under “Depreciation”. Depreciation is calculated on a straight line basis over the useful life of the asset applying individual rates to each type of asset, which are reviewed at th e end of each reporting period. The useful lives generally used by the Atento Group are as follow: Years of useful life Buildings 5 - 40 Plant and machinery 3 - 6 Furniture, tools 1 - 10 Other tangible assets 5 - 8
Description of accounting policy for impairment of assets [text block]	h) Impairment of non­current assets The Atento Group assesses as of each reporting date whether there is an indicator that a non­current asset may be impaired. If any such indicator exists, or when annual impairment testing for an asset is required (e.g. goodwill), the Atento Group estimates the asset’s recoverable amount . An asset’s recoverable amount is the higher of its fair value less costs to sell or its value in use. In assessing the value in use, the estimated future cash flow is discounted to its present value using a pre­tax discount rate that reflects current mar ket assessments of the time value of money and the risks specific to the asset. Where the carrying amount of an asset exceeds its recoverable amount, the asset is considered to be impaired. In this case, the carrying amount is written down to its recoverab le amount, and the resulting loss is recognized in the statement s of operations . Future depreciation/amortization charges are adjusted to reflect the asset’s new carrying amount over its remaining useful life. Management analyzes the impairment of each ass et individually, except in the case of assets that generate cash flow which are interdependent on those generated by other assets (cash generating units – “CGU” ). The Atento Group bases the calculation of impairment on the business plans of the various ca sh generating units to which the assets are allocated. These business plans cover five years. A long-term growth rate is calculated and applied to project future cash flows after the fifth year. When there are new events or changes in circumstances that i ndicate that a previously recognized impairment loss no longer exists or has been decreased, a new estimate of the asset’s recoverable amount is made. A previously recognized impairment loss is reversed only if there has been a change in the estimates used to determine the asset’s recoverable amount since the last impairment loss was recognized. If that is the case, the carrying amount of the asset is increased to its recoverable amount. The reversal is limited to the carrying amount that would have been de termined had no impairment loss been recognized for the asset in prior years. This reversal is recognized in the statement s of operations and the depreciation charge is adjusted in future periods to reflect the asset’s revised carrying amount. Impairment l osses relating to goodwill cannot be reversed in future periods.
Description of accounting policy for financial assets [text block]	i) Financial assets and liabilities Financial assets Upon initial recognition, the Atento Group classifies its financial assets into one of four categories: financial assets at fair value through profit or loss, loans and receivables, held­to­maturity investments and available­for­sale financial assets. Thes e classifications are reviewed at the end of each reporting period and modified if appropriate . The Atento Group has classified all of its financial assets as loans and receivables, except for derivative financial instruments. All purchases and sales of financial assets are recognized on the statement of financial position on the transaction date, i.e. when the commitment is made to purchase or sell the asset. A financial asset is fully or partially derecognized from the statement of financial position o nly when: The rights to receive cash flow from the asset have expired. The Atento Group has assumed an obligation to pay the cash flow received from the asset to a third party or The Atento Group has transferred its rights to receive cash flow from the as set to a third party, thereby substantially transferring all of the risks and rewards of the asset. Financial assets and financial liabilities are offset and presented on a net basis in the statement of financial position when a legally enforceable right exists to offset the amounts recognized and the Atento Group intends to settle the assets and liabilities net or to s imultaneously realize the asset and cancel the liability. Loans and receivables include fixed­maturity financial assets not listed in active markets and which are not derivatives. They are classified as current assets, except for those maturing more than twelve months after the reporting date, which are classified as non­current assets. Loans and receivables are initially recognized at fair value plus any transaction costs, and are subsequently measured at amortized cost, using the effective interest metho d. Interest calculated using the effective interest method is recognized under finance income in the statement s of operations . The Atento Group assesses at each reporting date whether a financial asset is impaired. Where there is objective evidence of imp airment of a financial asset valued at amortized cost, the amount of the loss to be taken to the statement s of operations is measured as the difference between the carrying amount and the present value of estimated future cash flow (without taking into acc ount future losses), discounted at the asset’s original effective interest rate. The carrying amount of the asset is reduced and the amount of the impairment loss is expensed in the consolidated statement s of operations . Trade receivables Trade receivabl es are amounts due from customers for the sale of services in the normal course of business. Receivables slated for collection in twelve months or less are classified as current assets; otherwise, the balances are considered non­current assets. Trade rece ivables are recognized at the original invoice amount. An impairment provision is recorded when there is objective evidence of collection risk. The amount of the impairment provision is calculated as the difference between the carrying amount of the doubtf ul trade receivables and their recoverable amount. In general, cash flow relating to short - term receivables is not discounted. Cash and cash equivalents Cash and cash equivalents comprise cash on hand and in banks, demand deposits and other highly liquid investments with an original maturity of three months or less , which are subject to an insignificant risk of changes in value . Financial liabilities D ebt with third parties (Borrowing) D ebt with third parties is initially recorded at the fair value of the consideration received, less any directly attributable transaction costs. After initial recognition, these financial liabilities are measured at amortized cost using the effective interest method. Any differe nce between the cash received (net of transaction costs) and the repayment value is recognized in the statement s of operations over the life of the debt. D ebt with third parties is considered to be non­current when the maturity date is longer than twelve m onths from the reporting date, or when the Atento Group has full discretion to defer settlement for at least another twelve months from that date. Financial liabilities are derecognized in the statement of financial position when the respective obligation is settled, cancelled or matures. Trade payables Trade payables are payment obligations in respect of goods or services received from suppliers in the ordinary course of business. Trade payables falling due in twelve months or less are classif ied as current liabilities; otherwise, the balances are considered as non­current liabilities.

Description of accounting policy for derivative financial instruments and hedging [text block]	j) Derivative financial instruments and hedging Derivative financial instruments are initially recognized at their fair values on the date on wh ich the derivative contract is e ntered into and are subsequently re-measured at their fair value. Any gains or losses resulting from changes in the fair value of a derivative instrument are recorded in the statements of operations , except for the effective portion of cash flow hedges, which is recognized in other comprehensive income/(loss) and later reclassified to profit or loss when the hedge item affects the statements of operations . At the inception of the derivative instrument contract , the Atento Group docum ents the relationship between the hedging instruments and the hedged items, as well as the risk management objectives and the strategy for groups of hedges. The Atento Group also documents its assessment, both at the inception of the hedge and throughout t he term thereof, of whether the derivatives used are highly effective at offsetting changes in the fair value or cash flow of the hedged items. The fair value of a hedging de rivative is classified as a non- current asset or liability, as applicable, if the remaining maturity of the hedged item exceeds twelve months, otherwise it is classified as a current asset or liability. For purpose of hedge accounting the Atento Group designates certain derivatives as either: Cash f low hedges Cash flow hedge is defined as a hedge of the exposure to variability in cash flows that is attributable to a particular risk associated with a recognized asset or liability (such as all or some future interest payments on variable rate debt) or a highly probable forecast transaction that could affect profit or loss. The effective portion of the gain or loss on the hedging instrument is recognized in other comprehensive income in the cash flow hedge reserve in equity. If a hedge of a forecast transaction subsequently results in the re cognition of a financial asset or a financial liability, any gain or loss on the hedging instrument that was previously recognized directly in equity is recycled from reserves into the statement s of operations in the same period(s) in which the financial a sset or liability affects profit or loss. Net investment hedges Gains or losses on the hedging instrument relating to the effective portion of the hedge are recognized in other comprehensive income. Gains or losses relating to the ineffective portion are recognized in the statements of operations . Gains and losses accumulated in equity are included in the statements of operations when the foreign operation is partially disposed of or sold.
Description of accounting policy for issued capital [text block]	k) Share capital The ordinary shares of the Company are classified in equity ( see N ote 19 ). Issuance costs directly attributable to the issuance of new shares or options are deducted from the proceeds raised in equity, net of the tax effect.
Description of accounting policy for provisions [text block]	l ) Provisions Provisions are recognized when the Atento Group has a present obligation (legal or constructive) as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation, and a reliable estimate can be made of the amount of the obligation . Provisions for restructuring include penalties for the cancellation of leases and other contracts, as well as employee termination payments. Provisions are not recognized for future operating losses. When the Atento Group is virtually certain that some or all of a provision is to be reimbursed, for example under an insurance contract, a separate asset is recognized in the statement of financial position, and the expense relating to the provision is recorded in the statements of operations, net of the exp ected reimbursement. Provisions are measured at the present value of expenditure expected to be required to settle the obligation, using a pre­tax rate that reflects current market assessments of the time value of money and the specific risks inherent to the obligation. Any increase in the provision due to the passage of time is recognized as a finance cost. Contingent liabilities represent possible obligations to third parties, and existing obligations that are not recognized, given that it is not likel y that an outflow of economic resources will be required in order to settle the obligation or because the amount cannot be reliably estimated. Contingent liabilities are not recognized on the consolidated statement of financial position unless they are rec orded as part of a business combination.
Description of accounting policy for share-based payment transactions [text block]	m ) Employee benefit Share­based payments Atento S.A. has a share­based compensation plan, under which the subsidiaries of Atento S.A. receive services from employees as consideration for the equity instruments of Atento S.A. The subsidiaries themselves are not party to any of the contracts; Atento S.A. settles these agreements. The plan offers various instruments (award agreements, stock options, restricted stock units, etc.), but so far only five types of restricted stock units (“RSUs”) have been granted to selected employees , being two on December 3, 2014 , two on July 1, 2016 and one on July 3, 2017. The fair value of the employee services received in exchange for the grant of the RSUs is recognized as an expense in the consolidated financial statements of Atento S.A. The total amount to be expensed is determi ned with reference to the fair value of the RSUs granted: • Including any market performance conditions (for example, an entity’s share price) ; • Excluding the impact of any service and non­market performance vesting conditions (for example, profitabilit y, sales growth targets and remaining an employee of the entity over a specified time period) ; and • Including the impact of any non­vesting conditions (for example, the requirement for employees to save or hold shares for a specific period of time). At t he end of each reporting period, the group revises its estimates of the number of RSUs that are expected to vest based on the non­market vesting conditions and service conditions. It recognizes the impact of the revisions to original estimates, if any, in the statements of operations , with a corresponding adjustment to equity. When the RSUs vest, Aten to S.A. issues new shares or buys them back in the market. The proceeds received, net of any directly attributable transaction costs, are credited to share ca pital (nominal value) and share premium. The social security contributions payable in connection with the granting of the share options is considered an integral part of the grant itself, and the charge will be treated as a cash­settled transaction.
Description of accounting policy for termination benefits [text block]	Term ination benefits Termination benefits are paid to employees when the Atento Group decides to terminate their employment contracts prior to the usual retirement age or when the employee agrees to resign voluntarily in exchange for these benefits. The Atent o Group recognizes these benefits as an expense for the year, at the earliest of the following dates: (a) when the Atento Group is no longer able to withdraw the offer for these benefits; or (b) when the Atento Group company recognizes the costs of a restr ucturing effort as per IAS 37, “Provisions, Contingent Liabilities and Contingent Assets”, and when this restructuring entails the payment of termination benefits. When benefits are offered in order to encourage the voluntary resignation of employees, term ination benefits are measured on the basis of the number of employees expected to accept the offer. Benefits to be paid in more than twelve months from the reporting date are discounted to their present value .
Description of accounting policy for income tax [text block]	n ) Income tax The income tax expense includes all the expenses and credits arising from the corporate income tax levied on all the Atento Group companies. Income tax expenses for each period represent the aggregate amounts of current and deferred taxes, if applicable. Current tax as sets and liabilities for the current and prior periods are measured at the amount expected to be recovered from or paid to the tax authorities. The tax rates and tax laws used to compute the amounts are those that are enacted at the reporting date in each country in which the Atento Group operates. The Atento Group determines deferred tax assets and liabilities by applying the tax rates that will be effective when the corresponding asset is received or the liability settled, based on tax rates and tax laws that are enacted (or substantively enacted) at the reporting date . Deferred taxes are calculated on temporary differences arising from differences between the tax bas i s of assets and liabilities and their carrying amounts f or financial reporting purposes. Deferred tax assets also arise from unused tax credits and tax loss carryforwards. The carrying amounts of deferred income tax assets are reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient future taxa ble profits will be available to allow all or part of that deferred tax asset to be utilized. Unrecognized deferred income tax assets are reassessed at each reporting date and are recognized to the extent that it has become probable that future taxable pro fits will allow the deferred tax asset to be recovered. Deferred tax liabilities associated with investments in subsidiaries and branches are not recognized when the timing of the reversal can be controlled by the parent company, and it is probable that t he temporary differences will not reverse in the foreseeable future. Deferred income tax relating to items directly recognized in equity is also recognized in equity. Deferred tax assets and liabilities resulting from business combinations are added to or deducted from goodwill. Deferred tax assets and liabilities are offset only if a lega lly enforceable right exists to off set current tax assets against current income tax liabilities and the deferred taxes relate to the same taxable entity and the same ta xation authority.
Description of accounting policy for recognition of revenue [text block]	o ) Revenue and expenses Revenue and expenses are recognized on the statement s of operations on an accruals basis, i.e. when the services are rendered , regardless of when actual payment or collection occurs. Revenue is measured at the f air value of the consideration received or to be received, and represents the amounts expected to be collected for services sold, net of discounts, returns and value added tax. Revenue is recognized when it can be reliably measured, when it is probable tha t the Group will receive a future economic benefit, and when certain conditions are met for each Group activity carried out. S ervices revenues are recognized when services are rendered, when the revenue and costs of the services contract, can be reliably estimated, and it is probable that the related receivables will be recovered. The Atento Group obtains revenue mainly from services provided to customer, recognizing the revenue when the call center services are performed or when certain contact center consulting work is carried out. Expenses are recognized in the statements of operations an accrual basis, regardless of when actual payment or collection occurs. The Atento Group’s incorporation, start­up and res earch expenses, as well as expenses that do not qualify for capitalization under IFRS, are recognized in the consolidated statements of operations when incurred and classified in accordance with their nature.
Description of accounting policy for interest income and expense [text block]	p ) Interest income and expenses Interest expe nses incurred in the construction of any qualified asset are capitalized during the time necessary to complete the asset and prepare it for the intended use. All other interest expenses are expensed a s incurred. Interest income is recognized using the effective interest method. When a loan or a receivable has been impaired, the carrying amount is reduced to the recoverable amount, discounting the estimated future cash flow at the instrument’s original effective interest rate and recognizing the discount as a decrease in interest income. Interest income on impaired loans is recognized when the cash is collected or on the basis of the recovery of the costs when the loan is secured.
Description of accounting policy for leases [text block]	q) Leases (as lessee) The Atento Group rents certain properties. Leases where the lessor does not transfer substantially all of the risks and benefits of ownership of the asset are classified as operating leases. Operating lease payments are recognized as an expense in the statements of operations on a straight line basis over the lease term. Those lease arrangements under which the Atento Group holds the significant risks and benefits inherent in owning the leased item are treated as finance leases. Finance leases are capitalized as an asset at the inception of the lease period and classified according to their nature. Finance leases are capitalized at the lower of the present value of the minimum lease payments agreed, and the fair value of the leased asset. Lease payments are proportionally allocated to the principal of the lease liability and to finance charges. Finance charges are reflected in the statements of operations over the lease term so as to achieve a constant rate of interest on the balance pending repayment in each period.
Description of accounting policy for explanation of sources of estimation uncertainty with significant risk of causing material adjustment	r ) Critical accounting estimates an d assumptions The preparation of consolidated financial statements under IFRS as issued by the IASB requires the use of certain assumptions and estimates that affect the carrying amount of assets and liabilities within the next financial year. Some of the accounting policies applied in preparing the accompanying consolidated financial statements required Management to apply significant judgments in order to select the most appropriate assumptions for determining these estimates. These assumptions and estim ates are based on Management experience, the advice of consultants and experts, forecasts and other circumstances and expectations prevailing at year end. Management’s evaluation takes into account the global economic situation in the sector in which the A tento Group operates, as well as the future outlook for the business. By virtue of their nature, these judgments are inherently subject to uncertainty. Consequently, actual results could differ substantially from the estimates and assumptions used. Should this occur, the values of the related assets and liabilities would be adjusted accordingly. Although these estimates were made on the basis of the best information available at each reporting date on the events analyzed, events that take place in the futu re might make it necessary to change these estimates in coming years. Changes in accounting estimates would be applied prospectively in accordance with the requirements of IAS 8, “Accounting Policies, Changes in Accounting Estimates and Errors”, recognizin g the effects of the changes in estimates in the related consolidated statement s of operations . An explanation of the estimates and judgments that entail a significant risk of leading to a material adjustment in the carrying amounts of assets and liabilit ies is as follow: Useful lives of property, plant and equipment and intangible assets The accounting treatment of items of property, plant and equipment and intangible assets entails the use of estimates to determine their useful lives for depreciation a nd amortization purposes. In determining the useful life, it is necessary to estimate the level of use of assets as well as forecast technological trends in the assets. Assumptions regarding the level of use, the technological framework and the future deve lopment require a significant degree of judgment, bearing in mind that these aspects are rather difficult to foresee. Changes in the level of use of assets or in their technological development could result in a modification of their useful lives and, cons equently, in the associated depreciation or amortization. I mpairment of goodwill The Atento Group tests goodwill for impairment annually, in accordance with the accounting principle described in Note 3h. Goodwill is subject to impairment testing as part of the cash­generating unit to which it has been allocated. The recoverable amounts of cash­generating units defined in order to identify potential impairment in goodwill are determined on the basis of value in use, applying five­year financial forecasts b ased on the Atento Group’s strategic plans, approved and reviewed by Management. These calculations entail the use of assumptions and estimates, and require a significant degree of judgment. The main variables considered in the sensitivity analyses are gro wth rates, discount rates using the Weighted Average Cost of Capital (“WACC”) and the key business variables. Deferred taxes The Atento Group assesses the recoverability of deferred tax assets based on estimates of future earnings. The ability to recover these deferred amounts depends ultimately on the Atento Group’s ability to generate taxable earnings over the period in which the deferred tax assets remain deductible. This analysis is based on the estimated timing of the reversal of deferred tax liabilities, as well as estimates of taxable earnings, which are sourced from internal projections. The appropriate classification of tax assets and liabilities depends on a series of factors, including estimates as to the timing and realization of deferred tax assets and the projected tax payment schedule. Actual income tax receipts and payments could differ from the estimates made by the Atento Group as a result of changes in tax legislation or unforeseen transactions that could affect the tax balances (see Note 2 0 ). The Atento Group has recognized deferred tax assets corresponding to losses carried forward since, based on internal pr ojections, it is probable th at it will generate future taxable profits against which they may be utilized. The carrying amount of deferred income tax assets is reviewed at each reporting date, and reduced to the extent that it is no longer probable that s ufficient taxable profits will be available to allow all or part of that deferred tax asset to be utilized. Unrecognized deferred income tax assets are reassessed at each reporting date and are recognized to the extent that it has become probable that futu re taxable profits will allow the deferred tax asset to be recovered. Provisions and contingencies Provisions are recognized when the Atento Group has a present obligation as a result of a past event, it is probable that an outflow of resources will be r equired to settle the obligation and a reliable estimate can be made of the amount of the obligation. This obligation may be legal or constructive, deriving from, inter alia, regulations, contracts, customary practice or public commitments that would lead third parties to reasonably expect that the Atento Group will assume certain responsibilities. The amount of the provision is determined based on the best estimate of the outflow of resources embodying economic benefit that will be required to settle the o bligation, taking into account all available information as of the reporting date, including the opinions of independent experts such as legal counsel or consultants. No provision is recognized if the amount of liability cannot be estimated reliably. In s uch cases, the relevant information is disclosed in the notes to the consolidated financial statements. Given the uncertainties inherent in the estimates used to determine the amount of provisions, actual outflows of resources may differ from the amounts recognized originally on the basis of these estimates (see Note 2 1 ). Fair valu e of derivatives The Atento Group uses derivative financial instruments to mitigate risks, primarily derived from possible fl uctuations in interest rates. Derivatives are recog nized at the inception of the contract at fair value. The fair values of derivative financial instruments are calculated on the basis of observable market data available, either in terms of market prices or through the application of valuation techniques . The valuation techniques used to calculate the fair value of derivative financial instruments include the discounting of future cash flow associated with the instruments, applying assumptions based on market conditions at the valuation date or using pric es established for similar instruments, among others. These estimates are based on available market information and appropriate valuation techniques. The fair values calculated could differ significantly if other market assumptions and/or estimation techni ques were applied.

Description of accountng policy for disclosure of expected impact of initial application of new standards or interpretations [text block]	t) New and amended standards adopted by the Group The Group has applied the following standards and amendments for the first time for thei r annual reporting period commencing on or after January 1, 2017: Recognition of Deferred Tax Assets for Unrealised Losses – Amendments to IAS 12 ; and Disclosure Initiative – Amendments to IAS 7 . The adoption of these amendments did not have any materia l impact on the current period or any prior period and is not likely to affect future periods. u) New standards and interpretations not yet adopted Certain new accounting standards and interpretations have been published that are not mandatory for December 31, 2017 reporting periods and have not been early adopted by the Group. The G roup’s assessment of the impact of these new standards and interpretations is set out below: Title of standard IFRS 9 Financial Instruments Nature of change IFRS 9 addresses the classification, measurement and recognition of financial assets and financial liabilities, introduces new rules for hedge accounting and a new impairment model for financial assets. Impact The Group has reviewed its financial assets and liabilities and is expecting the following impact from the adoption of the new standard on January 1, 2018: Financial assets The Company’s loans and receivables as per IAS 39 that are held to collect contractual cas h flows that solely represent payments and interest satisfy the conditions for classification as at amortized cost for IFRS 9 and hence there will be no change to the accounting for these assets. We also expect no changes for derivatives, that as per IAS 39 are classified at fair value through profit or loss (unless they are designated as hedges) and would appear to be classified as FVPL as per IFRS 9. Accordingly, the Atento Group does not expect the new guidance to have a significant impact on the cla ssification and measurement of its financial assets. Financial liabilities There will be no impact on the Atento Group’s accounting for financial liabilities, as the new requirements only affect the accounting for financial liabilities that are designat ed at fair value through profit or loss and the Atento Group does not have such liabilities other than derivatives, that as per IAS 39 are classified at fair value through profit or loss (unless they are designated as hedges) and will be classified as FVPL (fair value through profit or loss) as per IFRS 9. The derecognition rules have been transferred from IAS 39 Financial Instruments: Recognition and Measurement and have not been changed. The new hedge accounting rules will align the accounting for hedgi ng instruments more closely with the Atento Group’s risk management practices. As a general rule, more hedge relationships might be eligible for hedge accounting, as the standard introduces a more principles-based approach. The Atento Group’s current hedge relationships will qualify as continuing hedges upon the adoption of IFRS 9. Accordingly, the Atento Group does not expect a significant impact on the accounting for its hedging relationships. The new impairment model requires the recognition of impairment provisions based on expected credit losses (ECL) rather than only incurred credit losses as is the case under IAS 39. It applies to financial assets classified at amortized cost, debt instruments measured at FVOCI (fair value through other compr ehensive income), contract assets under IFRS 15 Revenue from Contracts with Customers, lease receivables, loan commitments and certain financial guarantee contracts. Management does not expect a significant increase in the credit losses, as well as losses on investments held at amortized cost. The new standard also introduces expanded disclosure requirements and changes in presentation. These are expected to change the nature and extent of the Atento Group’s disclosures about its financial instruments part icularly in 2018. Mandatory application date/ Date of adoption by the Group Must be applied for financial years commencing on or after January 1, 2018. The Group will apply the new rules retrospectively from January 1, 2018, with the practical expedi ents permitted under the standard. Comparatives for 2017 will not be restated. Title of standard IFRS 15 Revenue from Contracts with Customers Nature of change The IASB has issued a new standard for the recognition of revenue. This will replace IAS 18 which covers contracts for goods and services and IAS 11 which covers construction contracts. The new standard is based on the principle that revenue is recognised when control of a good or service transfers to a cus tomer. Impact Management has assessed the effects of applying the new standard on the Atento Group’s financial statements and has identified the following services that are likely to be affected: Accounting for certain costs incurred in fulfilling a contract – certain costs which are currently expensed may need to be recognised as an asset under IFRS 15. Variable consideration – IFRS 15 establishes that the Atento Group includes in the transaction price of services the amount of variable considerati on estimated only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur. Some contracts with customer may be impacted for this requirement due to the existence of clauses containing serv ice level requirements, trade discounts, penalties or volume rebates. This could result in different amounts being recognized and/or delay the recognition of a portion of the revenue. Presentation disclosure - IFRS 15 provides presentation and disclosure requirements, which are more detailed than under current IFRS. The presentation requirements represent a significant change from current practice and significantly increases the volume of disclosures required in Atento Group’s financial statements. Many of the disclosure requirements in IFRS 15 are completely new. The Atento Group is reassessing its systems, internal controls, policies and procedures necessary to collect and disclose the required information. The Atento’s Group continue to evaluate custom er contracts to determine the estimated variable consideration as disclosed above. Based on the assessment conducted in 2017, the Company and its subsidiaries do not foresee a significant impact through the adoption of IFRS 15. Mandatory application date/ Date of adoption by the Group The Group intends to adopt the standard using the modified retrospective approach as of January 1, 2018 and the comparatives will not be restated. Title of standard IFRS 16 Leases Nature of change IFRS 16 was issued in January 2016. It will result in almost all leases being recognised on the balance sheet, as the distinction between operating and finance leases is removed. Under the new standard, an asset (the right to use the leased item) and a financial liability to pay rentals are recognised. The only exceptions are short-term and l ow-value leases. The accounting for lessors will not significantly change. Impact The standard will affect primarily the accounting for the Atento Group’s operating leases. As at the reporting date, the Atento Group has operating lease commitments of 240,113 thousand U.S. dollars. However, the Atento Group has not yet determined to what extent these commitments will result in the recognition of an asset and a liability for future payments and how this will affect the Atento Group’s profit and classification of cash flows. Some of the commitments may be covered by the exception for short-term and low-value leases and some commitments may relate to arrangements that will not qualify as leases under IFRS 16. Mandatory applica tion date/ Date of adoption by group Mandatory for financial years commencing on or after January 1, 2019. At this stage, the Atento Group does not intend to adopt the standard before its effective date. Title of standard IFRS 2 Classification and Measurement of Share-based Payment Transactions — Amendments to IFRS 2 Key requirements The IASB issued amendments to IFRS 2 Share-based Payment that address three main areas: the effects of vesting conditions on the measurement of a cash-settled s hare-based payment transaction; the classification of a share-based payment transaction with net settlement features for withholding tax obligations; and accounting where a modification to the terms and conditions of a share-based payment transaction ch anges its classification from cash settled to equity settled. Mandatory application date/ Date of adoption by group On adoption, entities are required to apply the amendments without restating prior periods, but retrospective application is permitted i f elected for all three amendments and other criteria are met. The amendments are effective for annual periods beginning on or after January 1, 2018, with early application permitted. Expected date of adoption by t he Atento Group is January 1, 2018 . Title of standard IFRIC Interpretation 22 Foreign Currency Transactions and Advance Consideration Key requirements The Interpretation clarifies that, in determining the spot exchange rate to use on initial recognition of the related asset, expense or income (or part of it) on the derecognition of a non-monetary asset or non-monetary liability relating to advance consideration, the date of the transaction is the date on which an entity initially recognises the non-monetary asset or non-monetary liabilit y arising from the advance consideration. If there are multiple payments or receipts in advance, then the entity must determine the transaction date for each payment or receipt of advance consideration. Entities may apply the amendments on a fully retrospe ctive basis. Mandatory application date/ Date of adoption by group Alternatively, an entity may apply the Interpretation prospectively to all assets, expenses and income in its scope that are initially recognised on or after: (i) The beginning of the reporting period in which the entity first applies the interpretation ; or (ii) The beginning of a prior reporting period presented as comparative information in the financial statements of the reporting period in which the entity first applies the interpr etation. The Interpretation is effective for annual periods beginning on or after January 1, 2018. Early application of interpretation is permitted and must be disclosed. Expected date of adoption by t he Atento Group is January 1, 2018. Title of standard IFRIC Interpretation 23 Uncertainty over Income Tax Treatment Key requirements The Interpretation addresses the accounting for income taxes when tax treatments involve uncertainty that affects the application of IAS 12 and does not apply to taxes or levies outside the scope of IAS 12, nor does it specifically include requirements relating to interest and penalties associated with uncertain tax treatments. The Interpretation specifically addresses the following: Whether an entity co nsiders uncertain tax treatments separately ; The assumptions an entity makes about the examination of tax treatments by taxation authorities ; How an entity determines taxable profit (tax loss), tax bases, unused tax losses, unused tax credits and tax rates ; How an entity considers changes in facts and circumstances. Mandatory application date/ Date of adoption by group An entity must determine whether to consider each uncertain tax treatment separately or together with one or more other uncertain tax treatments. The approach that better predicts the resolution of the uncertainty should be followed. The interpretation is effective for annual reporting periods beginning on or after January 1, 2019, but certain transition reliefs are available. The G roup will apply interpretation from its effective date.
