ACCOUNTING POLICIES

Disclosure Of Significant Accounting Policies Abstract
Disclosure Of Summary Of Significant Accounting Policies Explanatory	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 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 re turns 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 lo ses 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 G roup. Non-controlling interests in the results and equity of subsidiaries are shown separately in the consolidated statements of operations, statement of comprehensive income/(loss), statement of changes in equity and financial position. (ii) Business comb inations and goodwill When the Atento Group acquires a business, it assesses the financial assets acquired and liabilities assumed for appropriate classification and designation in accordance with the contractual terms, economic circumstances and pertinent conditions as at the acquisition date. This includes the separation of embedded derivatives in host contracts by the acquire. Any contingent consideration to be transferred by the acquirer will be recognized at fair value at the acquisition date. Continge nt consideration classified as equity is not remeasured and its subsequent settlement is accounted for within equity. Contingent consideration classified as an asset or liability that is a financial instrument and within the scope of IFRS 9 Financial Instr uments, is measured at fair value with the changes in fair value recognized in the statement of profit or loss in accordance with IFRS 9. Other contingent consideration that is not within the scope of IFRS 9 is measured at fair value at each reporting date with changes in fair value recognized in profit or loss. Goodwill is initially measured as any excess of the total consideration transferred over the net identifiable assets acquired and liabilities assumed. If the fair value of the net assets acquired is greater than the total consideration transferred, the difference is recognized in the statements of operations as a gain from a bargain purchase. Goodwill acquired in a business combination is allocated to each cash-generating unit, or group of cash-gener ating units, that are expected to benefit from the synergies arising in the business combination. Goodwill is tested for impairment annually or whenever there are certain events or changes in circumstances indicating potential impairment. The carrying amou nt of the assets allocated to each cash-generating unit is then compared 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 ma y not be reversed (see Note 3h). b) Functional and presentation currency 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 curre ncy of the Atento Group. c) Foreign 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:  Statem ent 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 approximat ion 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 dates of the transactions) .  Hyperinflationary economies: Under IAS 29, the non-monetary assets and liabilities, the equity and the statements of operations of subsidiaries operating in hyperinflationary economies are restated applying a general price index. The financial statements of an entity whose functional currency is the currency of a hyperinflationary economy, whether they are based on a historical cost approach or a current cost approach, shall be stated in terms of the measuring unit current at the end of the reporting period and translated to U.S. dolla r at the closing rate of the period , for the purposes of conversion, applying IAS 21.  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 proceeds and payments are translated at the rate on the da tes of the transactions). Proceeds and payments for the subsidiary located in Argentina shown on the statements of cash flows are translated at the exchange rates prevailing at the reporting date.  Retained earnings are translated at historical excha nge rates .  All resulting exchange differences are recognized in other comprehensive 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 foreig n 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 date, 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 exchan ge rates of monetary assets and liabilities denominated in foreign currencies are 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 hedges that are accounted for as an effective hedge against a net investment in a foreign entity . These differences are recognized in other comprehensive income/(loss) (OCI) until the hedge settlement and disposal of the net investment, at which time, they are recognized in the statements of operations. Tax charges and credits attributable to exchang e differences on those monetary items are also recorded in OCI. Non–monetary items that 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 informati on 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 business from a geographical perspective and analyzes it across three operational segm ents– EMEA, Americas and Brazil. N o operating segments have been aggregated to form the reporta ble operating segments as compared to the previous years. f) I ntangible assets Intangible assets are stated at acquisition cost, less any accumulated amortization and any accumulated impairment losses. The intangible assets acquired in a business combina tion 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 assets 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 reco verable. Intangible assets that have an indefin ite useful 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 “ Amortizati on”. Amortization methods and useful lives are revised annually at the end of each reporting period and, where appropriate, adjusted prospectively. Customer base Customer base acquired in a business combination is recognized at fair value at the acquisitio n 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 base relate to all agreements, tacit or explicit, entered into between the A tento 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. Software Software is measured at cost (at acquisit ion or development costs) and amortized on a straight-line basis over its useful life, generally estimated to be between three and ten 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 providing 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 appropriate percentage of overheads. Costs that do not meet the criteria listed above are recognized as an expense as incurred. Expendi ture 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 amortiz ed 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 . Acquisition cos ts include, whe n appropriate, the initial estimates of decommissioning, withdrawal and site reconditioning 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 th e assets and maintenance costs are recognized directly in the statement s of operations . Costs that 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 assesses the need to write down, if appropriate, the carrying amount of each item of property, plant and equipment to its period-end recoverable amount w henever there are indications that the assets’ carrying amount may not be fully recoverable through the generation of sufficient future revenue. The impairment allowance is reversed if the factors giving rise to the impairment cease to exist. The depreciat ion charge for items of property, plant and equipment is recognized in the consolidated statement s of operations under “Depreciation”. Depreciation is calculated on a straight-line basis over the useful life of the asset applying individual rates to each t ype 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 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 cas h 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 ind icate 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 t o 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 dete rmined if 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 loss es relating to goodwill cannot be reversed in future periods. i) Financial assets and liabilities Financial assets Initial recognition and measurement Financial assets are classified, at initial recognition, as subsequently measured at amortized cost, fair value through other comprehensive income (OCI), and fair value through profit or loss. The Atento Group has classified all financial assets as amortized cost , except for derivative financial instruments. All purchases and sales of financial ass ets 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 only when: 1. The rights to receive cash flow from the asset have expired. 2. The Atento Group has assumed an obligation to pay the cash flow received from the asset to a third party or 3. The Atento Group has transferred its rights to receive cash flow from the asset 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 simultaneously realize the asset and cancel the liability. Amortized cost financial assets include fixed maturity financial assets not listed in active mark ets 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 p lus any transaction costs, and are subsequently measured at amortized cost, using the effective interest method. Interest calculated using the effective interest method is recognized under finance income in the statement s of operations . The Atento Group as sesses at each reporting date whether a financial asset is impaired. Where there is objective evidence of impairment 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 differ ence between the carrying amount and the present value of estimated future cash flow, 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 consolida ted statement s of operations . Trade receivables Trade receivables 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; otherwi se, the balances are considered non­current assets. These are financial assets measured initially at fair value and subsequently, at amortized cost and are evaluated by the value of the services provided in accordance with the contracted conditions, net of estimated impairment losses. These include the services provided to customers, which were still not billed at the balance sheet date. In general, cash flow relating to short - term receivables is not discounted. C ash 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 ( Loans and Borrowings ) 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 measur ed at amortized cost using the effective interest method. Any difference 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 consid ered to be non­current when the maturity date is longer than twelve months 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 classified as current liabilities; otherwise, the balances are considered as non­current liabilities. 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 remeasured at their fair value. Any gains or losses resulting from changes in the fair value of a derivative instrument are recorded in the st atements of operations , except for the effective portion of cash flow and net investment 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 documents 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 do cuments its assessment, both at the inception of the hedge and throughout the 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 rivativ e 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 rese rve in equity. If a hedge of a forecast transaction subsequently results in the recognition 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 reserve s into the statement s of operations in the same period(s) in which the financial asset 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 ot her 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 dispos ed of or sold. 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. l) Treasury shares Own equity instruments that are reacquired (treasury shares) are recognized at cost and deduct ed from equity. No gain or loss is recognized in profit or loss on the purchase, sale, issue or cancellation of the Atento Group’s own equity instruments. Any difference between the carrying amount and the consideration, if reissued, is recognized in the s hare premium. m ) 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 relati ng to the provision is recorded in the statements of operations, net of the expected 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 mar ket assessments of the time value of money and the specific risks inherent to the obligation. Contingent liabilities represent possible obligations to third parties, and existing obligations that are not recognized, given that it is not likely that an outf low 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 recorded as part of a business combination. n ) 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 some types of restricted stock units (“RSUs”) have been granted to selected employees , as described in Note 19. The fair value of the employee services received in exchange for the grant of the RSUs is rec ognized as an expense in the consolidated financial statements of Atento S.A. The total amount to be expensed is determined with reference to the fair value of the RSUs granted:  Including any market performance conditions (for example, an entity’s share pr ice) ;  Excluding the impact of any service and non­market performance vesting conditions (for example, profitability, sales growth targets and remaining an employee of the entity over a specified time period) ; and  Including the impact of any non­vesting con ditions (for example, the requirement for employees to save or hold shares for a specific period of time). At the 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 t he market. The proceeds received, net of any directly attributable transaction costs, are credited to share capital (nominal value) and share premium. The social security contributions payable in connection with the granting of the share options is conside red an integral part of the grant itself, and the charge will be treated as a cash­settled transaction. Termination 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 Atento 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 restructuring effort as per IAS 37, “Provisions, Contingent Liabilities and Contingent Assets”, and when this restructuring entails the payment of termina tion benefits. When benefits are offered in order to encourage the voluntary resignation of employees, termination 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 fr om the reporting date are discounted to their present value . o ) 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 assets and liabilities for the current and prior periods are measured at the amount expected to be recovered from or paid to the t ax 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 arisin g 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 taxable profits will be available to allow all or part of that deferred tax asset to be utilized. Unrecognized deferred income tax ass ets are reassessed at each reporting date and are recognized to the extent that it has become probable that future taxable profits will allow the deferred tax asset to be recovered. Deferred tax liabilities associated with investments in subsidiaries and b ranches are not recognized when the timing of the reversal can be controlled by the parent company, and it is probable that the temporary differences will not reverse in the foreseeable future. Deferred income tax relating to items directly recognized in e quity 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 taxation authority. p ) Revenue and E xpenses Revenue and 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 research expenses, as well as expenses that do not qualify for capitalization under IFRS, are recognized in t he consolidated statements of operations when incurred and classified in accordance with their nature. q ) Interest income and expenses Interest expenses 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 u sing 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. r) Leases (as lessee) Until December 31, 2018, the Atento Group r ent ed certain properties. Leases where the lessor does not transfer substantially all of the risks and benefits of ownership of the asset were classified as operating leases. Operating lease payments were 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 were treated as finance leases. Finance leases were capitalized as an asset at the inception of the lease period and classified according to their nature. Finance leases were capitalized at the lower of the present value of the minimum lease payments agreed, and the fair value of the leased asset. Lease payments were proportionally allocated to the principal of the lease liability and to finance charges. Finance ch arges 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. From January 1, 2019, the Group has adopted IFRS 16 Leases , but

Disclosure of risk management strategy related to hedge accounting [abstract]
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 risk Intere st rate risk in respect of cash flow and fair value Interest 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 fluctuations in interest rates. At December 31, 2020 , 4.5 % of financial debt with third parties bore interests at variable rates, while at December 31, 2019 t his amount was 0.2 %. In both 201 9 and 20 20 , the exposure was to the Brazilian CDI rate and the TJLP (Brazilian Long -Term Interest Rate). The Atento Group’s policy is to monitor the exposure to interest at risk. As of December 31, 20 20 , there were no outstanding interest rate hedging instruments. 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 g enerally 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 derivatives to hedge any exposure incurred in curre ncies other than those of the functional currency of the c ountries . The main source of our foreign currency risk is related to the Senior Secured Notes due 2022 denominated in U.S. dollars. Upon issuance of the Notes, we entered into cross-currency swaps p ursuant to which we exchange an amount of U.S. dollars for a fixed amount of Euro, Mexican Pesos, Peruvian Soles and Brazilian Reais. The total amount of interest (coupon) payments are covered (until maturity date). The referred cross-currency swaps are the only derivative transactions we have in place in Atento Group. As of December 31, 20 20 , the estimated f air value of the cross-currency swaps totaled a net asset of 5,868 thousand U.S. dollars ( net asset of 3,093 thousand U.S. dollars as of December 31, 201 9 ). The table below shows the impact of a +/­10 percentage points variation in the exchange rate on the val ue of the cross-currency swaps .

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 Atento Group has no material adjustments to make to its credit accounts (s ee 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 r elationship 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. Thes e placements are regulated by our Corporate Treasury policy on the basis of the conditions prevailing in the markets and the countries where Atento operates. The Corporate Treasury policy establishes: (i) the maximum amounts to be invested per counterparty, b ased 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 invested. The Atento Group’s maximum exposure to credit risk is primarily limited to the carrying amounts of its financial assets. The Atento Group holds no guarantees as collection insurance. 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 long enough to support business operation normal conditions (assuming that internal projections are met). A maturity schedule for the Atento Group’s f inancial 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 , as going concern, 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 n ormal conditions and to address new opportunities for growth. Debt levels are kept in line with forecast ed future cash flows and with quantitative restrictions imposed under financing contracts. In addition to these general guidelines, we take into account other considerations and specifics when determining our finan cial structure, such as country risk , tax efficiency and volatility in cash flow generation. The Super Senior Revolving Credit Facility, described in Note 17, carries no financial covenant obli gations regarding debt levels. However, the notes do impose limitations on dividend distributions, payments or distributions to the shareholders, the incurrence of additional debt, and on investments and disposal of assets. As of the date of these consolid ated financial statements, the Atento Group was in compliance with all restrictions established in the aforementioned financing contracts and does not foresee any future non-compliance. To that end, the Atento Group regularly monitors figures for net finan cial debt with third parties and EBITDA. Net financial debt with third parties at December 31, 2019 and 2020 is as follows: Thousands of U.S. dollars 2018 2019 Senior Secured Notes (Note 17) 400,035 501,922 Brazilian bonds - Debentures (Note 17) 14,708 - Bank borrowings (Note 17) 39,498 23,928 Lease liabilities (Note 17) 5,527 194,765 Less: Cash and cash equivalents (Note 15) (133,526) (124,706) Net financial debt with third parties 326,242 595,909

Disclosure of business combinations [text block]	5) ACQUISITION OF NON-CONTROLLING INTERESTS 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. Put/Call options As per the Shareholders' Agreement, the Company had a purchase option, where non-controlling shareholders irrevocably and irreversibly granted to the Company, through that instrument, the right, but not the obligation, at the sole discretion of the Company, to acquire all of their shares, and the non-controlling shareholders, through the exercise of that right, would be obliged to sell their shares to the Company ("call option"). The call option might be exercised by any controlling shareholder between January 1, 2019 and December 31, 2020. The Shareholders' Agreement also provided for a put option, where the non-controlling shareholders had the right, irrevocable and irreversible, but not the obligation, to sell all of their shares to the Company ("put option" ). The put option might be exercised by non-controlling shareholders between January 1, 2019 and December 31, 2020. On the basis of the above, the Company recognized as of September 2, 2016 a financial liability related to the potential for acquisition of non-controlling interest f or an amount of 3,444 thousand Brazilian Reais ( 1,057 thousand U . S . dollars). The financial liability was initially recognized against specific reserve in equity. In the acquisition of non-controlling interest this reserve was reversed. The exercise price of the call option would 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. On June 7, 2019, th e Company acquired to the remaining interest of 18.51 % of the shares of RBrasil. The total amount paid for this acquisition was 1, 738 thousand U.S. dollars 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 Interfi le 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. Put/Call options As per the Shareholders' Agreement, the Company ha d a purchase option, where non-controlling shareholders granted 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, would be obliged to sell their shares to Atento Brasil S.A. ("call option"). The call option m ight be exercised by Atento Brasil S.A. between January 1, 2020 and April 15, 2020. The Shareholders' Agreement also provide d for put options, where the non-controlling shareholders ha d t he right, to sell partial or all of their shares to the Atento Brasil S.A. ("put options"). Many put options were understood by Management 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 term extension or acceleration of other options) and (iii) function: effective options or clauses protecting the parties. Considerin g the valuation of the acquired entity and Management’s best estimates, the put option that w ould likely to be exercised by the non-controlling shareholders was between January 1, 2020 and April 15, 2020 – which was symmetrical with the call option. Accord ing 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 pu t option w ould 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. On the basis of the above, t he Company recognized on June 9, 2017 a financial liability related to the potential acquisition of non-controlling interest of 74,401 thousand Brazilian Reais ( 22,474 thousand US dollars). The financial liability was recognized against specific reserve in equity, considering that these are transactions between shareholders. In the acquisition of non-controlling interest this reserve was reversed. On May 17, 2019, the Company acquired to the remaining interest of 49.99998 % of Interfile. The total amount paid for this acquisition was 14, 089 thousand U.S. dollars.

IMPAIRMENT OF ASSETS

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, 2020 , 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 cash - generating units to which goodwill is allocated . The Atento Group carries out its goodwill impairment tests to all CGUs using the various cash-generating units’ five-year strategic plans and budgets. The three-yea r plan used as the basis for the impairment test was approved by the board of directors on the date of February 24, 2021. Recoverable amount is based on value in use calculated using cash flow from projected results adjusted for amortization/depreciation, finance 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 u sing the WACC applicable to that CGU. The discount rates used reflect the current assessment of specific market risks in each of the cash-generating units, considering the time value of money and individual country risks not included in the cash flow estim ates. 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 spe cific 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, 2020, the tests conducted did not identify a ny 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 . At December 31, 2019, all CGUs, except Argentina, passed in the impairment tests with projections to support all assets. We wrote-off those assets in Argentina in 2019. In Argentina, with the deterioration of the economic situation, discount rates increa sed significantly, making discounted cash flow of the operations not enough to cover its asset base. The test resulted in an impairment of 30,909 thousand U.S. dollars in 2019 . The calculation of values in use for the CGUs is most sensitive to the revenues , EBITDA and discount rates assumptions. The CGUs revenues projection has a variation based on management expectations growth plus inflation and the EBITDA margin has a variability range from + 1.7 p.p. to +4.8p.p. The pre-¬tax discount rates, which factor i n country and business risks, and the projected terminal growth rates were as follow: Discount rate Brazil Mexico Colombia Peru Chile Argentina December 2019 14.87% 15.82% 10.42% 11.82% 9.52% 92.14% December 2020 16.47% 15.94% 12.58% 14.41% 13.92% 80.25% Terminal Growth rate Brazil Mexico Colombia Peru Chile Argentina December 2019 4.81% 5.47% 6.40% 7.11% 6.41% 30.29% December 2020 4.31% 2.65% 6.29% 3.33% 3.88% 40.50% The carrying amounts per CGUs were as follow: Thousand U.S. dollars Carrying Amount Brazil Mexico Colombia Peru Chile Argentina December 2019 275,231 99,070 33,824 69,214 36,654 36,442 December 2020 188,847 79,610 31,242 59,153 35,991 1,778 In the event of a 3% increase in the discount rate used to calculate the recoverable amount of the abovementioned CGUs in each country, with the other variables remaining unchanged, the recoverable amount would still be higher than the corresponding carrying amount. This sensitivity is on the reasonability of the management expectations. 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 . As an additional sensitivity analysis, assuming that there is a fall in demand or an increase in costs and, as such, results before amortization/depreciation, finance cost and taxes margin (EBITDA margin) used for estimating cash flow were to keep consta nt 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 certa in CGU , the following assumptions were used: Cash flow for Brazil, Mexico, Spain, Colombia, Peru Chile and Argentina CGUs were estimated based on growth projections considering the management expectation of the business performance, using predicted inflati on levels taken from external sources.

Disclosure of derivative financial instruments [text block]	14 ) DERIVATIVE FINANCIAL INSTRUMENTS Details of derivative financial instruments at December 31, 2019 and 2020 are as follow: Thousands of U.S. dollars 2019 2020 Assets Liabilities Assets Liabilities Cross currency swaps - net investment hedges 5,382 (2,289) 11,088 (5,220) Cross currency swaps - that do not meet the criteria for hedge accounting - (167) - - Total 5,382 (2,456) 11,088 (5,220) Non-current portion 5,382 (2,289) 11,088 (5,220) Current portion - (167) - - Atento Luxco1 entered into Cross-Currency Swaps to reduce its foreign exchange risk, since it generates cashflow in local currencies. With these instruments, the company ensures that its cashflow in local currencies is swapped into a fixed dollar amount, the currency used to pay debt obligations, therefore reducing foreign exchange risks. Derivatives held for trading are classified as current assets or current liabilities. The fair value of a hedging derivative is classified as a non-current asset or a non -current liability, as applicable, if the remaining maturity of the hedged item exceeds twelve months. Otherwise, it is classified as a current asset or liability. In connection with the Refinancing process and the repayment of the first Brazilian Debentur es, the hedge accounting for the interest rate swap was discontinued and the OCI balance was transferred to finance cost. Thereafter, any changes in fair value was directly recognized in the statements of operations. On April 1, 2015, the Company started a hedge accounting for net investment hedge related to exchange risk between the U.S. dollar and foreign operations in Euro (EUR), Mexican Peso (MXN), Colombian Peso (COP) and Peruvian Nuevo Sol (PEN). In connection with the Refinancing process, 8 of the 10 derivatives contracts designated as Net Investment Hedges were terminated between August 1, 2017 and August 4, 2017, generating positive cash of 46,080 thousand U.S. dollars, net of charges. During August 2017, Atento Luxco 1 also entered into new Cross-C urrency Swaps related to exchange risk between U.S. dollars and Euro (EUR), Mexican Peso (MXN), Brazilian Reais (BRL) and Peruvian Nuevo Sol (PEN). Except for the Cross-Currency Swap between U.S. dollars and Brazilian Reais (BRL), all Cross-Currency Swaps were designated for hedge accounting as net investment hedge. On January 01, 2019, the Company started to also designate the Cross-Currency Swap between U.S. dollars and Brazilian Reais (BRL) for hedge accounting as net investment hedge. On January 1, 2019 , the Company designated the Cross-Currency Swap between U.S. dollars and Brazilian Reais for hedge accounting as net investment hedge. Prior to the date of designation of the Cross-Currency Swap, this hedging instrument was electively not designated as a hedge accounting because the change in fair value was intended to partially offset changes in the USD-BRL foreign currency component of the BRL denominated intercompany debt, which were recorded in earnings. Effective January 1, 2019, the intercompany debt was reclassified as “permanent in equity” (which assumes that the related payable is neither planned nor likely to occur in the foreseeable future, since it is in substance, a part of the entity’s net investment in that foreign operation) and, as a conseq uence, the changes arising from the exchange rate are recorded in other comprehensive income. On January 1, 2020 Atento decided to assign the loan agreement between Atento Luxco 1 and Atento Mexico Holdco as “permanent in equity”, with its maturities to be renewed per indefinite time, since the repayment is neither planned nor likely to occur in the foreseeable future. Therefore, changes related to the USD-MXN exchange rate are now recorded in other comprehensive income. On February 14, 2020, Atento Brasil S.A. entered into a cross-currency swap to hedge a EURO loan of 7,402 thousand Euros at a fixed rate of 1.49% exchanged to a 35,000 thousand Brazilian Reais with interest rate of the average daily rate of the one day “over extra-group” – DI – Interbank Dep osits - plus a spread of 1.95% per annum. The transaction was liquidated on August 13, 2020 due to the repayment of the loan.

Mezzanine Partners II Offshore Lux Sarl II owns 25.36 %; Chesham Investment Pte Ltd owns 21.85 %, Taheebo Holdings LLC owns 14,8 7 % of ordinary shares of Atento S.A. Reserve for acquisition of non-controlling interest Refers to options attributable t o Atento Brasil S.A. in the acquisition of RBrasil and Interfile in the total amount of 23,531 thousand U.S. dollars as of December 31, 2018. On May 17, 2019 and June 7, 2019, the Company acquired remaining shares of Interfile and RBrasil, respectively, and therefore the reserve for acquisition of non-controlling interest was written off. 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. On January 2 , 2020, the Company vested the total of 1,305,065 TRSUs , issued by treasury shares, with an impact in sh are premium of 5,842 thou sand of U.S. dollars. Treasury shares In 2019, Atento S.A. repurchased 4,425,499 shares (corresponding to 880,330 shares of the reserve share split) at a cost of 11,141 thousand of U.S. dollars and an average price of $2.52 ($12.66 in reverse share split basis), totalizing 5,531,657 shares in treasury (corresponding to 1,100,639 shares of the reserve share split). As a result of the vesting of 1,305,065 TRSUs (corresponding to 259,606 shares of the reserve share split), Atento S.A. had 4,226,592 shares in treasury (corresponding to 840,763 sha res of the reserve share split). As of July 28, 2020, Atento S . A . announced a reverse share split that converted the Company’s entire share capital of 75,406,357 into 15,000,000 shares. At that time Atento S.A. had 4,771,076 shares on treasury that became 949,073. Considering the reverse share split basis, during 2020, Atento S.A. repurchased 169,739 shares at a cost of 1,337 thousand of U.S. dollars and an average price of $7.87. As of December 31, 2020, Atento S.A. had 1,010,502 shares in treasury (1,100,369 shares as of December 31, 2019, in the reverse share split ba sis). Legal reserve According to commercial legislation in Luxembourg, Atento S.A. must transfer 5% of its year profits to legal reserve until the amount reaches 10% of share capital. The legal reserve cannot be distributed. At December 31, 201 9 and 20 20 , no legal reserve had been established, mainly due to the losses incurred by Atento S.A. On February 26, 2020, the Board of Directors has proposed the allocation to legal reserve of the amount of sixty-seven with forty-seven cents Euros (EUR 67.47). At July 28, 2020 the Annual Meeting resolves to (i) allocate the amount of EUR 67.47 to the legal reserve of the Company out of the profit of EUR 1,071,315.52 and (ii) to carry forward the remaining amount of the profit to the next financial year. Hedge accountin g effects As discussed on Note 14, on January 1, 2019 Atento formalized at a meeting of the “Board of Directors”, which took place on December 20, 2018, its intention to renew the loan agreement between Atento Luxco 1 and Atento Brasil on its maturities per indefinite time and designate it as permanent equity, as the repayment is neither planned nor likely to occur in the foreseeable future. Therefore, changes in fair value related to the USD-BRL exchange rate is rec orded in equity as part of other comprehensive income. At the same time the, on January 1, 2019, the Cross-Currency Swap USD BRL was designated as a net investment hedge. Prior to the date of designation of the Cross-Currency Swap, this hedging instrument was electively not designated as a hedge accounting because the change in fair value was intended to partially offset changes in the USD-BRL foreign currency component of the BRL denominated intercompany debt, which were recorded in earnings. Therefore, ch anges in fair value related to the USD-BRL Cross-Currency Swap are recorded in equity as part of other comprehensive income. Also, on January 1, 2020 the Company assigned the loan agreement between Atento Luxco 1 and Atento Mexico Holdco as permanent in eq uity, with its maturities to be renewed per indefinite time, since the repayment is neither planned nor likely to occur in the foreseeable future. Therefore, changes in fair value related to the USD-MXN exchange rate are now recorded in equity as part of o ther comprehensive income. 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).

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 EB ITDA (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. • The Americas, which includes the activities carried out by th e various Spanish-speaking companies in Mexico, Central and South America. It also includes tra nsactions in the United States. • Brazil, which is managed separately in view of its different language and major importance. The Atento Group uses EBITDA to track the performance 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 managem ent to evaluate and compare the segments’ 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 izati on), and tax consequences. EBITDA is defined 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 depreciation and amortization. EBITDA is 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 be comparable to similar indicators used by ot her companies.

ACCOUNTING POLICIES (Policies)

ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2020
Disclosure Of Significant Accounting Policies 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 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 re turns 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 lo ses 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 G roup. Non-controlling interests in the results and equity of subsidiaries are shown separately in the consolidated statements of operations, statement of comprehensive income/(loss), statement of changes in equity and financial position.
Description of accounting policy for business combinations and goodwill [text block]	(ii) Business comb inations and goodwill When the Atento Group acquires a business, it assesses the financial assets acquired and liabilities assumed for appropriate classification and designation in accordance with the contractual terms, economic circumstances and pertinent conditions as at the acquisition date. This includes the separation of embedded derivatives in host contracts by the acquire. Any contingent consideration to be transferred by the acquirer will be recognized at fair value at the acquisition date. Continge nt consideration classified as equity is not remeasured and its subsequent settlement is accounted for within equity. Contingent consideration classified as an asset or liability that is a financial instrument and within the scope of IFRS 9 Financial Instr uments, is measured at fair value with the changes in fair value recognized in the statement of profit or loss in accordance with IFRS 9. Other contingent consideration that is not within the scope of IFRS 9 is measured at fair value at each reporting date with changes in fair value recognized in profit or loss. Goodwill is initially measured as any excess of the total consideration transferred over the net identifiable assets acquired and liabilities assumed. If the fair value of the net assets acquired is greater than the total consideration transferred, the difference is recognized in the statements of operations as a gain from a bargain purchase. Goodwill acquired in a business combination is allocated to each cash-generating unit, or group of cash-gener ating units, that are expected to benefit from the synergies arising in the business combination. Goodwill is tested for impairment annually or whenever there are certain events or changes in circumstances indicating potential impairment. The carrying amou nt of the assets allocated to each cash-generating unit is then compared 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 ma y not be reversed (see Note 3h).
Description of accounting policy for functional currency [text block]	b) Functional and presentation currency 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 curre ncy of the Atento Group.
Description of accounting policy for foreign currency translation [text block]	c) Foreign 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:  Statem ent 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 approximat ion 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 dates of the transactions) .  Hyperinflationary economies: Under IAS 29, the non-monetary assets and liabilities, the equity and the statements of operations of subsidiaries operating in hyperinflationary economies are restated applying a general price index. The financial statements of an entity whose functional currency is the currency of a hyperinflationary economy, whether they are based on a historical cost approach or a current cost approach, shall be stated in terms of the measuring unit current at the end of the reporting period and translated to U.S. dolla r at the closing rate of the period , for the purposes of conversion, applying IAS 21.  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 proceeds and payments are translated at the rate on the da tes of the transactions). Proceeds and payments for the subsidiary located in Argentina shown on the statements of cash flows are translated at the exchange rates prevailing at the reporting date.  Retained earnings are translated at historical excha nge rates .  All resulting exchange differences are recognized in other comprehensive 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 foreig n 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 date, 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 exchan ge rates of monetary assets and liabilities denominated in foreign currencies are 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 hedges that are accounted for as an effective hedge against a net investment in a foreign entity . These differences are recognized in other comprehensive income/(loss) (OCI) until the hedge settlement and disposal of the net investment, at which time, they are recognized in the statements of operations. Tax charges and credits attributable to exchang e differences on those monetary items are also recorded in OCI. Non–monetary items that 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 informati on 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 business from a geographical perspective and analyzes it across three operational segm ents– EMEA, Americas and Brazil. N o operating segments have been aggregated to form the reporta ble operating segments as compared to the previous years.
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 losses. The intangible assets acquired in a business combina tion 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 assets 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 reco verable. Intangible assets that have an indefin ite useful 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 “ Amortizati on”. Amortization methods and useful lives are revised annually at the end of each reporting period and, where appropriate, adjusted prospectively. Customer base Customer base acquired in a business combination is recognized at fair value at the acquisitio n 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 base relate to all agreements, tacit or explicit, entered into between the A tento 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. Software Software is measured at cost (at acquisit ion or development costs) and amortized on a straight-line basis over its useful life, generally estimated to be between three and ten 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 providing 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 appropriate percentage of overheads. Costs that do not meet the criteria listed above are recognized as an expense as incurred. Expendi ture 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 amortiz ed 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 . Acquisition cos ts include, whe n appropriate, the initial estimates of decommissioning, withdrawal and site reconditioning 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 th e assets and maintenance costs are recognized directly in the statement s of operations . Costs that 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 assesses the need to write down, if appropriate, the carrying amount of each item of property, plant and equipment to its period-end recoverable amount w henever there are indications that the assets’ carrying amount may not be fully recoverable through the generation of sufficient future revenue. The impairment allowance is reversed if the factors giving rise to the impairment cease to exist. The depreciat ion charge for items of property, plant and equipment is recognized in the consolidated statement s of operations under “Depreciation”. Depreciation is calculated on a straight-line basis over the useful life of the asset applying individual rates to each t ype 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 cas h 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 ind icate 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 t o 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 dete rmined if 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 loss es 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 Initial recognition and measurement Financial assets are classified, at initial recognition, as subsequently measured at amortized cost, fair value through other comprehensive income (OCI), and fair value through profit or loss. The Atento Group has classified all financial assets as amortized cost , except for derivative financial instruments. All purchases and sales of financial ass ets 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 only when: 1. The rights to receive cash flow from the asset have expired. 2. The Atento Group has assumed an obligation to pay the cash flow received from the asset to a third party or 3. The Atento Group has transferred its rights to receive cash flow from the asset 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 simultaneously realize the asset and cancel the liability. Amortized cost financial assets include fixed maturity financial assets not listed in active mark ets 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 p lus any transaction costs, and are subsequently measured at amortized cost, using the effective interest method. Interest calculated using the effective interest method is recognized under finance income in the statement s of operations . The Atento Group as sesses at each reporting date whether a financial asset is impaired. Where there is objective evidence of impairment 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 differ ence between the carrying amount and the present value of estimated future cash flow, 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 consolida ted statement s of operations . Trade receivables Trade receivables 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; otherwi se, the balances are considered non­current assets. These are financial assets measured initially at fair value and subsequently, at amortized cost and are evaluated by the value of the services provided in accordance with the contracted conditions, net of estimated impairment losses. These include the services provided to customers, which were still not billed at the balance sheet date. In general, cash flow relating to short - term receivables is not discounted. C ash 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 ( Loans and Borrowings ) 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 measur ed at amortized cost using the effective interest method. Any difference 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 consid ered to be non­current when the maturity date is longer than twelve months 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 classified 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 remeasured at their fair value. Any gains or losses resulting from changes in the fair value of a derivative instrument are recorded in the st atements of operations , except for the effective portion of cash flow and net investment 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 documents 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 do cuments its assessment, both at the inception of the hedge and throughout the 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 rivativ e 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 rese rve in equity. If a hedge of a forecast transaction subsequently results in the recognition 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 reserve s into the statement s of operations in the same period(s) in which the financial asset 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 ot her 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 dispos ed 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 Treasury Shares Explanatory	l) Treasury shares Own equity instruments that are reacquired (treasury shares) are recognized at cost and deduct ed from equity. No gain or loss is recognized in profit or loss on the purchase, sale, issue or cancellation of the Atento Group’s own equity instruments. Any difference between the carrying amount and the consideration, if reissued, is recognized in the s hare premium.
Description of accounting policy for provisions [text block]	m ) 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 relati ng to the provision is recorded in the statements of operations, net of the expected 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 mar ket assessments of the time value of money and the specific risks inherent to the obligation. Contingent liabilities represent possible obligations to third parties, and existing obligations that are not recognized, given that it is not likely that an outf low 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 recorded as part of a business combination.
Description of accounting policy for share-based payment transactions [text block]	n ) 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 some types of restricted stock units (“RSUs”) have been granted to selected employees , as described in Note 19. The fair value of the employee services received in exchange for the grant of the RSUs is rec ognized as an expense in the consolidated financial statements of Atento S.A. The total amount to be expensed is determined with reference to the fair value of the RSUs granted:  Including any market performance conditions (for example, an entity’s share pr ice) ;  Excluding the impact of any service and non­market performance vesting conditions (for example, profitability, sales growth targets and remaining an employee of the entity over a specified time period) ; and  Including the impact of any non­vesting con ditions (for example, the requirement for employees to save or hold shares for a specific period of time). At the 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 t he market. The proceeds received, net of any directly attributable transaction costs, are credited to share capital (nominal value) and share premium. The social security contributions payable in connection with the granting of the share options is conside red 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]	Termination 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 Atento 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 restructuring effort as per IAS 37, “Provisions, Contingent Liabilities and Contingent Assets”, and when this restructuring entails the payment of termina tion benefits. When benefits are offered in order to encourage the voluntary resignation of employees, termination 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 fr om the reporting date are discounted to their present value .
Description of accounting policy for income tax [text block]	o ) 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 assets and liabilities for the current and prior periods are measured at the amount expected to be recovered from or paid to the t ax 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 arisin g 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 taxable profits will be available to allow all or part of that deferred tax asset to be utilized. Unrecognized deferred income tax ass ets are reassessed at each reporting date and are recognized to the extent that it has become probable that future taxable profits will allow the deferred tax asset to be recovered. Deferred tax liabilities associated with investments in subsidiaries and b ranches are not recognized when the timing of the reversal can be controlled by the parent company, and it is probable that the temporary differences will not reverse in the foreseeable future. Deferred income tax relating to items directly recognized in e quity 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 taxation authority.
Description of accounting policy for recognition of revenue [text block]	p ) Revenue and E xpenses Revenue and 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 research expenses, as well as expenses that do not qualify for capitalization under IFRS, are recognized in t he consolidated statements of operations when incurred and classified in accordance with their nature.
Description of accounting policy for interest income and expense [text block]	q ) Interest income and expenses Interest expenses 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 u sing 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]	r) Leases (as lessee) Until December 31, 2018, the Atento Group r ent ed certain properties. Leases where the lessor does not transfer substantially all of the risks and benefits of ownership of the asset were classified as operating leases. Operating lease payments were 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 were treated as finance leases. Finance leases were capitalized as an asset at the inception of the lease period and classified according to their nature. Finance leases were capitalized at the lower of the present value of the minimum lease payments agreed, and the fair value of the leased asset. Lease payments were proportionally allocated to the principal of the lease liability and to finance charges. Finance ch arges 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. From January 1, 2019, the Group has adopted IFRS 16 Leases , but has not restated comparati ves for the 2018 reporting period, as permitted under the specific transition provisions in the standard. The reclassifications and the adjustments arising from the new leasing rules are therefore recognized in the opening balance sheet on January 1, 2019. A s explained in N ote 3u below, the Group has changed its accounting policy for leases where the Group is the lessee. The Atento Group assesses at contract inception whether a contract is, or contains, a lease. That is, if the contract conveys the right t o control the use of an identified asset for a period of time in exchange for consideration. Atento Group as a lessee The Atento Group applies a single recognition and measurement approach for all leases, except for short-term leases and leases of low-value assets. The Group recognizes lease liabilities to make lease payments and right-of-use assets representing the right to use the underlying assets. (i) Right-of-use assets The Group recognizes right-of-use assets at the commencement date of the lease (i.e., the date the underlying asset is available for use). Right-of-use assets are measured at cost, less any accumulated depreciation and impairment losses, and adjusted for any remeasurement of lease liabilities. The cost of right-of-u se assets includes the amount of lease liabilities recognized, initial direct costs incurred, and lease payments made at or before the commencement date less any lease incentives received. Right-of-use assets are depreciated on a straight-line basis over t he shorter of the lease term and the estimated useful lives of the assets . (ii) Lease liabilities At the commencement date of the lease, the Group recognizes lease liabilities measured at the present value of lease payments to be made over the lease term. The lease payments include fixed payments (including in - substance fixed payments) less any lease incentives receivable, variable lease payments that depend on an index or a rate, and amounts expected to be paid under residual value guarantees. In calculati ng the present value of lease payments, the Group uses its incremental borrowing rate at the lease commencement date because the interest rate implicit in the lease is not readily determinable. After the commencement date, the amount of lease liabilities is increased to reflect the accretion of interest and reduced for the lease payments made. In addition, the carrying amount of lease liabilities is remeasured if there is a modification, a change in the lease term, a change in the lease payment s (e.g., changes to future payments resulting from a change in an index or rate used to determine such lease payments) or a change in the assessment of an option to purchase the underlying asset. ( iii) Short-term leases and leases of low-value assets The G roup applies the short-term lease recognition exemption to its short-term leases of machinery (i.e., those leases that have a lease term of 12 months or less from the commencement date). It also applies the lease of low-value assets recognition exemption t o leases of office equipment that are considered to be low value. Lease payments on short-term leases and leases of low value assets are recognized as expense on a straight-line basis over the lease term.
Description of accounting policy for explanation of sources of estimation uncertainty with significant risk of causing material adjustment	s ) Critical accounting estimates and assumptions Th e 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 polic ies 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 estimates 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 Atento Group opera tes, 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 v alues 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 future might make it necessary to change these estimates in coming years. Changes in accounting estimates would be applied prospectively in accorda nce with the requirements of IAS 8, “Accounting Policies, Changes in Accounting Estimates and Errors”, recognizing 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 liabilities is as follow: I mpairment of goodwill The Atento Group tests goodwill for impairment annually, in accordance with the accounting p olicies 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 d etermined on the basis of value in use, applying five­year financial forecasts based 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 degre e of judgment. The main variables considered in the sensitivity analyses are growth 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 def erred 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 ana lysis 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 f actors, 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 legis lation 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 projections, it is probable th at it will generate futur e 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 sufficient taxable profits will be available to allow a ll 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 profits will allow the deferred tax asset t o 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 required 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 obligation, 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 such cases, the relevant information is disclosed in the n otes 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 exchange rates. Derivatives are recognized 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 va lue 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 prices established for similar instruments, among others. Th ese 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 techniques were applied. Update On COVID-19 The estimates and assumptions included in the financial statements include our assessment of potential impacts arising from the COVID-19 pandemic that may affect the amounts reported and the accompanying notes. To-date, no significant impacts on our collection experience an d expected credit losses have been noted and we do not currently anticipate any material impairments of our long-lived assets or of our indefinite-lived intangible assets as a result of the COVID-19 pandemic. We will continue to monitor the impacts and wil l prospectively revise our estimates as appropriate.

At December 31, 2018 , 2019 and 2020 , 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 .
Description of accountng policy for disclosure of expected impact of initial application of new standards or interpretations [text block]	u) New standards adopted in 2019 IFRS 16 was issued in January 2016. It resulted in almost all leas es being recognized 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 recognized. The only exceptions a re short-term and low-value leases. The standard affected primarily the accounting for the G roup’s operating leases. On January 1, 2019, lease commitments that the group recognized as right-of-use assets amount 184,099 thousand U.S. dollars, and lease liab ilities in the same amount. The Group adopted IFRS 16 in accordance with the modified retrospective approach. The prior-year figures were not adjusted. The consolidated statement of operations was impacted by a decrease of operating expenses and an increas e of the amortization of the right-of-use assets and interest on the lease liability . As at the reporting date, lease commitments of the G roup are recognized as right-of-use assets amount to 181,564 thousand U.S. dollars and lease liabilities in the amount of 194,765 thousand U.S. dollars on December 31, 2019. The following reconciliation to the opening balance for the lease liabilities as at January 1, 2019 is based upon the operating lease obli gations as at December 31, 2018: December 31, 2018 IFRS 16 January 1, 2019 Assets Right-of-use assets (*) 5,798 184,099 189,897 Liabilities (**) Non-current liabilities Lease liabilities (2,369) (132,551) (134,920) Current liabilities Lease liabilities (3,158) (51,548) (54,706) (*) Recorded in property, plant and equipment as of December 31, 2018. (**) Recorded as lease liabilities in Debt with third parties. IFRIC 23 Uncertainty over Income Tax Treatment Atento reviewed the tax treatment under the terms of IFRIC 23 in all subsidiaries and as at the reporting date, the G roup did not identify any material impact on the financial statements. Atento implemented a process for periodically review the income tax treatments consistent under IFRIC 23 requirements across the G roup. v) New and amended standards adopted by the Group The Atento Group applied the amendments to IAS 1 and IAS 8 and to IFR S 3 for the first time in 20 20 . The nature and effect of the changes as a result of adoption of these new accounting standards are described below. Amendments to IAS 1 and IAS 8 Definition of Material In October 2018, the IASB issued changes to IAS 1 and IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, to clarify the definition of “material” and to align the definition used in the Conceptual Framework and the standards themselves. The new definition states that “the information is material if its omission, distortion or obscuration can reasonably influence decisions that the main users of the general purpose financial statements make based on these financial statements, which provid e financial information on the entity’s specific report”. Amendments to IFRS 3 Definition of a Business In October 2018, the IASB issued changes to the definition of a business in IFRS 3, to help entities determine whether it has acquired a business or a group of assets. They clarify minimum requirements, eliminate the assessment of whether market participants are able to re place any missing elements, add guidance and illustrative examples to help entities assess whether a substantive process has been acquired , better define business and product definitions, and introduce a n optional concentration test. The adoption of these changes had no impact on the consolidated financial statements in the initial adoption period (January 1, 2020). w) Standards issued but not yet effective There are no other standards that are not yet effective and that would be expected to have a material impact on the Atento Group in the current or future reporting periods and on foreseeable future transactions.

Disclosure of objectives, policies and processes for managing capital [abstract]
Information about nature of lessee's leasing activities	r) Leases (as lessee) Until December 31, 2018, the Atento Group rented certain properties. Leases where the lessor does not transfer substantially all of the risks and benefits of ownership of the asset were classified as operating leases. Operating lease payments were 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 were treated as finance leases. Finance leases were capitalized as an asset at the inception of the lease period and classified according to their nature. Finance leases were capitalized at the lower of the present value of the minimum lease payments agreed, and the fair value of the leased asset. Lease payments were 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. From January 1, 2019, the Group has adopted IFRS 16 Leases, but has not restated comparatives for the 2018 reporting period, as permitted under the specific transition provisions in the standard. The reclassifications and the adjustments arising from the new leasing rules are therefore recognized in the opening balance sheet on January 1, 2019. As explained in Note 3u below, the Group has changed its accounting policy for leases where the Group is the lessee. The Atento Group assesses at contract inception whether a contract is, or contains, a lease. That is, if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Atento Group as a lessee The Atento Group applies a single recognition and measurement approach for all leases, except for short-term leases and leases of low-value assets. The Group recognizes lease liabilities to make lease payments and right-of-use assets representing the right to use the underlying assets. (i) Right-of-use assets The Group recognizes right-of-use assets at the commencement date of the lease (i.e., the date the underlying asset is available for use). Right-of-use assets are measured at cost, less any accumulated depreciation and impairment losses, and adjusted for any remeasurement of lease liabilities. The cost of right-of-use assets includes the amount of lease liabilities recognized, initial direct costs incurred, and lease payments made at or before the commencement date less any lease incentives received. Right-of-use assets are depreciated on a straight-line basis over the shorter of the lease term and the estimated useful lives of the assets. (ii) Lease liabilities At the commencement date of the lease, the Group recognizes lease liabilities measured at the present value of lease payments to be made over the lease term. The lease payments include fixed payments (including in-substance fixed payments) less any lease incentives receivable, variable lease payments that depend on an index or a rate, and amounts expected to be paid under residual value guarantees. In calculating the present value of lease payments, the Group uses its incremental borrowing rate at the lease commencement date because the interest rate implicit in the lease is not readily determinable. After the commencement date, the amount of lease liabilities is increased to reflect the accretion of interest and reduced for the lease payments made. In addition, the carrying amount of lease liabilities is remeasured if there is a modification, a change in the lease term, a change in the lease payments (e.g., changes to future payments resulting from a change in an index or rate used to determine such lease payments) or a change in the assessment of an option to purchase the underlying asset. (iii) Short-term leases and leases of low-value assets The Group applies the short-term lease recognition exemption to its short-term leases of machinery (i.e., those leases that have a lease term of 12 months or less from the commencement date). It also applies the lease of low-value assets recognition exemption to leases of office equipment that are considered to be low value. Lease payments on short-term leases and leases of low value assets are recognized as expense on a straight-line basis over the lease term.

IFRS 16 - Leases [member]
Disclosure of expected impact of initial application of new standards or interpretations [line items]
Discussion of impact that initial application of new IFRS is expected to have on financial statements	New standards adopted in 2019 IFRS 16 was issued in January 2016. It resulted in almost all leases being recognized 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 recognized. The only exceptions are short-term and low-value leases. The standard affected primarily the accounting for the Group’s operating leases. On January 1, 2019, lease commitments that the group recognized as right-of-use assets amount 184,099 thousand U.S. dollars, and lease liabilities in the same amount. The Group adopted IFRS 16 in accordance with the modified retrospective approach. The prior-year figures were not adjusted. The consolidated statement of operations was impacted by a decrease of operating expenses and an increase of the amortization of the right-of-use assets and interest on the lease liability
