CONSOLIDATED FINANCIAL
STATEMENTS

AS OF AND FOR THE YEAR ENDED
DECEMBER 31, 2020

Independent auditor’s report

To the shareholders

Interconexión Eléctrica S.A. E.S.P. and its subsidiaries

We have audited the consolidated financial statements of Interconexión Eléctrica S.A. E.S.P. and subsidiaries (hereinafter, the Company), which comprise the consolidated statement of financial position as of December 31, 2020 and the related consolidated statements of income and other comprehensive income (loss), changes in shareholders’ equity and cash flows for the year then ended, and the related notes (collectively referred to as the “consolidated financial statements”).

Management´s Responsibilities for the Financial Statements

Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with Financial Information Standards Accepted in Colombia; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of financial statements that are free of material misstatement, whether due to fraud or error.

Auditor’s Responsibilities

Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial statements. The procedures selected depend on the auditor’s judgment, including the assessment of the risks of material misstatement of the financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity’s preparation and fair presentation of the financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the financial statements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Basis for Qualified Opinion

The Company’s consolidated financial statements do not disclose comparative information in respect of the preceding period as specified in International Accounting Standards 1, Presentation of Financial Statements. In our opinion, disclosure of this information is required by Financial Information Standards Accepted in Colombia.

Qualified Opinion

In our opinion, except for the omission of the information described in the Basis for Qualified Opinion paragraph, the accompanying consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2020 and the consolidated results of its operations and its cash flows for the year then ended in accordance with Financial Information Standards Accepted in Colombia.

Accounts Receivable from the Brazilian Government

As described in Note 5 of the consolidated financial statements, CTEEP, a subsidiary of Interconexión Eléctrica S.A. E.S.P. through ISA Capital do Brasil, recorded a net balance of accounts receivable from the Sao Paulo State of approximately $1,175,056 million, related to the impacts of Law 4.819 of 1958, which granted to the employees of companies subject to the control of the Sao Paulo State benefits already granted to other public servers. CTEEP has undertaken legal actions before the respective State authorities to collect these accounts receivable. The accompanying financial statements do not include adjustments that could result from the outcome of this uncertainty. Our opinion is not modified by this matter.

INTERCONEXIÓN ELÉCTRICA S.A. E.S.P. AND SUBSIDIARIES

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

AS OF DECEMBER 31, 2020

(Amounts expressed in millions of Colombian pesos, except otherwise noted)

1. General information

Interconexión Eléctrica S.A. E.S.P. (“ISA” or the “Company”), with headquarters in Medellín, was incorporated as joint stock company by public deed No. 3057, issued by the 8^th Notary Office of the Notarial Circuit of Bogotá on September 14, 1967.

On November 22, 1996, by public deed No. 746 issued by the Sole Notary Office of Sabaneta, ISA changed its legal nature to Mixed Utility Company, incorporated as a Joint Venture of commercial and national nature, linked to the Ministry of Mines and Electricity, with indefinite term, and subject to the legal regime provided for by Law 142 of 1994, a situation that materialized on January 15, 1997 with the entry of private contributions.

In accordance with the considerations of the Constitutional Court in its ruling C-736 dated September 19, 2007, ISA has a special legal nature by being defined as a Mixed Utility Company, decentralized by services, which is part of the executive branch of the public power with special and legal regime of private law.

Headquarters are in Medellín, calle 12 Sur # 18-168.

The principal activities of ISA and its subsidiaries (collectively, “The Group”) are:

● The provision of the Electricity Transmission services.

● The development of information and telecommunication technology systems, activities, and services.

● The direct or indirect participation in activities and services related to the transport of other energies.

● The provision of technical and non-technical services related to its principal activities.

● The development of infrastructure projects and their commercial operation.

● The investment in other companies.

● Design, construction, operation, and maintenance of road infrastructure.

2. Significant Accounting Policies

2.1 Basis of Preparation

The Group prepares its consolidated financial statements in accordance with Financial Information Standards Accepted in Colombia (“NCIF”), which are compiled and updated through Decree 2270 of 2019 based on Decree 2420 of 2015 and subsequent modifications and other legal provisions applicable to entities supervised and/or controlled by the Colombian Superintendence of Corporations and General Accounting Office (“Contaduría General de la Nación”). The Financial Information Standards Accepted in Colombia correspond to International Financial Reporting Standards (IFRS) issued by the International Accounting Standards Board (IASB).

The Group´s consolidated financial statements as of and for the year ended December 31, 2020, prepared under Financial Information Standards Accepted in Colombia do not present any significant differences as compared with International Financial Reporting Standards issued by the IASB.

The consolidated financial statements have been prepared on a historical cost basis, except for derivative financial instruments and debt and equity financial assets that have been measured at fair value.

The consolidated financial statements are presented in Colombian pesos and all values are rounded to the nearest million, except when otherwise indicated.

The Group has prepared the consolidated financial statements on the basis that it will continue to operate as a going concern.

2.2 Consolidation principles

The consolidated financial statements include the financial statements of ISA and all of its subsidiaries, including structured entities that are controlled by ISA as of December 31, 2020. Subsidiaries are entities over which the Group exerts direct or indirect control.

8

Structured entities are established through contractual agreements with financial institutions for the management of resources that do not have voting rights. Structured entities over which ISA exerts control are Fundo de Investimento Referenciado di Bandeirantes, Fundo de Investimento Xavantes Referenciado di, Fundo de Investimento Assis and Fundo de Investimento Barra Bonita Renda Fixa Referenciado through the subsidiary ISA CTEEP.

The Group controls an entity when it exerts control over it (through existing rights that grant it the authority to direct the entity´s relevant activities); when it is exposed to or has rights to variable returns from its involvement with the entity and it has the ability to affect those returns through its power over the same. This occurs when ISA has less than the majority of the voting rights over an investee but still has the power over the investee to direct the entity’s relevant activities unilaterally.

The Group considers all relevant facts and circumstances when evaluating whether it controls an investee, including:

● The percentage of voting rights, and the participation and dispersion of percentages of voting rights held by others;

● Potential voting rights held by the Group and others;

● Rights arising from contractual agreements; and

● Any additional facts or circumstances indicating that the Group has, or lacks, the current ability to direct relevant activities when decision-making is needed, including voting patterns in previous shareholders’ meetings.

The financial statements of subsidiaries are included in the consolidated financial statements from the date on which the Group’s control commences over the subsidiary, until the date on which control ceases.

All intercompany assets and liabilities, revenues, expenses, and cash flows related to the Group’s intercompany transactions are eliminated in consolidation. Non-controlling interest represents the portion of the income, other comprehensive income and net assets in subsidiaries that are not attributable to ISA’s shareholders.

On the date the Group obtains control over an entity, the subsidiary´s assets and liabilities are recorded at fair value, excluding certain assets and liabilities that are recorded following the valuation principles set out in other IFRS.

Investments in subsidiaries are recorded based on financial statements as of the reporting date, under Financial Information Standards Accepted in Colombia (“NCIF”) and translated into Colombian pesos according to the provisions of IAS 21, based on their functional currency and using the U.S. dollar as reference currency. The income and financial position of subsidiaries of ISA that use a functional currency that is different from the presentation currency, are translated into the presentation currency as follows:

a. Assets and liabilities are translated into Colombian pesos at the closing rate, which corresponds to the Representative Market Rate (RMR) on the balance sheet date, certified by the Financial Superintendence of Colombia.

b. Revenue and expense items are translated into Colombian pesos at the average exchange rate in force at the end of each period, unless it changes significantly, in which case the exchange rates of the date when the transaction is performed, are to be used.

c. Equity is stated at the historical exchange rate on the acquisition or contribution date, and at the average exchange rate on the date of generation, in the case of accumulated income.

d. If applicable, exchange differences that arise are recognized in other comprehensive income and are accumulated in equity, in gains (losses) from conversion exchange differences (attributed to the non-controlling interest, as appropriate).

Accounting policies of the Group’s subsidiaries, associates, and jointly controlled companies are applied consistently. In the investments in associates and joint ventures, the Group applies the equity method of accounting.

An associate is an entity over which the Company is able to exercise significant influence, through the power to participate in decisions about its operating and financial policies.

In general, the significant influence is presumed in cases where the Group’s interest in an associate exceed 20%, even though, as in the case of control, it must be evaluated.

A joint venture is an agreement whereby the parties exerting joint control have rights to the net assets of the entity. Joint control only occurs when the decisions on relevant activities require the unanimous consent of the parties sharing control.

The equity method is a method of accounting whereby the investment in associates and jointly controlled entities is initially recognized at cost and adjusted thereafter for the post-acquisition change in the investor’s share of the investee’s net assets. The net profit or loss for the period and other comprehensive income of the entity that applies the equity method include its share of the profit or loss for the period and other comprehensive income of the entity. Dividends received from these entities are recorded as lower value of the investment in the associate or jointly controlled entity.

9

Transactions that imply a loss of control or significant influence over an associate or a jointly controlled entity are accounted for by recognizing any retained interest at its fair value, and the gain or loss resulting from the transaction is recognized in the income for the period, including the corresponding items of other comprehensive income.

Regarding transactions that do not imply a loss of control or significant influence over the associate or jointly controlled entity, the equity method remains being applied and the portion of the gain or loss recognized in other comprehensive income relating to the reduction in the stake of the property is reclassified in income.

2.3 Business combinations

2.3.1ORAZUL ELECTRICITY GROUP

The Group, through its subsidiary ISA PERU, entered into an agreement for the acquisition of 100% interest in ORAZUL ELECTRICITY GROUP and 0.004% interest in ORAZUL ELECTRICITY TRANSMISSION. On August 24, 2020, upon meeting the closing conditions the acquisition was completed.

ORAZUL ELECTRICITY GROUP holds a 99.976% ownership in ORAZUL ELECTRICITY TRANSMISSION, which holds a 99.999% interest in ETENORTE and ETESELVA, concessions acquired in perpetuity that operate six electric electricity transmission lines in Peru, totaling 746 kilometers of circuit. The transmission lines located in central and northern Peru in the departments of Ancash, Cajamarca, Huánuco, Lambayeque, and Uyacali operate in the Peruvian Primary Transmission System (SPT) and Secondary Transmission System (SST).

This transaction had the purpose of increasing the Group’s presence in the Peruvian market and increased its market share to 73% based on revenue, thus consolidating its position as the largest electricity transmission company in Peru.

The consideration paid for the acquisition of control of ORAZUL ELECTRICITY GROUP was COP 595,095 (USD 158,254,066).

Assets acquired and liabilities incurred at acquisition date

2.3.2 RUTA COSTERA

On October 24, 2019, the Group, through its subsidiary INTERCONEXIONES VIALES, signed a share purchase and sale agreement for the acquisition of 100% stake of RUTA COSTERA, owned by MHC Ingeniería y Construcción de Obras Civiles S.A.S., Constructora MECO S.A., Constructora Colpatria S.A. and Castro Tcherassi S.A.

On October 22, 2020, the acquisition transaction was completed once the closing conditions were met, including authorizations from the National Infrastructure Agency (ANI), insurers and concession funders.

RUTA COSTERA was incorporated in Colombia and entered into Concession Contract No. 004 with ANI on September 10, 2014. This Fourth Generation (4G) Concession has six operating units with 146 kilometers of roads and connects two main cities (Tranche 1: Cartagena-Barranquilla 110 km, and Tranche 2: Circunvalar de la Prosperidad between Malambo and Barranquilla, 36 km of double lane). The project comprises the Gran Manglar Viaduct, located on Ciénaga de la Virgen, Cartagena (5.4 km)

This transaction represents an important movement for implementing the strategy in the Road Concessions business unit in which the Group intends to participate in Colombia and Peru, consistent with its objective of diversifying its main electricity transmission business unit.

The purchase price to control RUTA COSTERA was COP 531,454.

2.4 Application of standards implemented in Colombia as of January 1, 2020

According to Decree 2270 of 2019, the following standards came into force within the technical regulatory framework.

ISA concluded that the adoption of these standards and interpretations did not have a material impact on the consolidated financial statements.

2.4.1IFRIC 23 – Uncertainty over income tax treatments

This interpretation clarifies how to apply the requirements for the recognition and measurement of IAS 12 when there is uncertainty over income tax treatments. In this case, an entity will recognize and measure its deferred or current tax asset or liability by applying IAS 12 requirements based on the taxable profit (tax loss), tax bases, unused tax losses, unused tax credits, and tax rates determined by applying this interpretation.

The Group conducted a practical analysis of IFRIC 23, determining that to recognize and measure deferred and current tax assets and liabilities when there is uncertainty about the acceptance of a tax treatment, the interpretation that is most likely to be accepted by the entities in charge of examining tax returns should be applied. The Group also concluded that an impact on the financial statements should only result from the application of this IFRIC when an item with uncertain treatment is estimated differently, by applying the interpretation with the highest tax acceptance.

The Group applied this standard in advance, from 2019.

2.4.2 IAS 1 – Presentation of financial statements

The amendments align the definition of “Material” between IAS 1 – Presentation of Financial Statements and IAS 8 – Accounting policies, changes in accounting estimates, and errors, and clarify certain aspects of the definition. The new definition establishes that “Information is material if omitting, misstating or obscuring it could reasonably be expected to influence decisions that the primary users of general-purpose financial statements make on the basis of those financial statements, which provide financial information about a specific reporting entity.”

2.4.3 IAS 19 – Employee benefits

Amendments to IAS 19 define the accounting treatment of any amendment, curtailing, or settlement of a plan that occurs during a financial year. Said changes specify that when a plan is amended, curtailed, or settled during the reporting year, the entity is required to:

● Determine the current cost of the service for the remaining period after the plan is amended, curtailed, or settled, applying the actuarial assumptions that are used to recalculate the net liability (asset) for defined provisions, reflecting the benefits offered and the plan assets after that event.

● Determine the net interest for the remaining period after the plan is amended, curtailed, or settled, by using: the net liability (asset) of the defined benefit that reflects the benefits offered under the plan and plan assets after that event, and the discount rate used to recalculate that net liability (asset) of the defined benefit.

The amendments also clarify that the entity first shall determine any past service cost, or settlement gain or loss, regardless of the effect of the asset ceiling. This amount is recognized as a profit or loss. The effect of the asset ceiling after the plan amendment, curtailment, or settlement is then determined and any changes in such effect, excluding amounts included in net interest, are recorded in other comprehensive income.

2.4.4 IFRS 3 – Business combinations

This interpretation clarifies that, to be considered a business, a set of activities and assets acquired must include, at least, an input and a substantive process where these contribute significantly to the capacity to create outputs. It restricts the definitions of a business and outputs by focusing on goods and services provided to customers and by eliminating the reference to the capacity to reduce costs. It provides guidance and graphic examples to help entities assess whether a substantive process has been acquired. It eliminates the assessment on market participants’ capacity to replace any missing inputs or processes and continue the production of outputs, and adds an optional concentration test, which allows for a simplified assessment about a set of activities and assets acquired not being a business.

14

2.4.5 Conceptual framework

It contains definitions of concepts related to:

● Measurement: including factors considered when selecting measurement bases.

● Presentation and disclosure: including when to classify revenues or expenses in other comprehensive income.

● Non-recognition: including guidance on when assets or liabilities should be removed from the financial statements.

Additionally, it updates definitions of assets and liabilities as well as criteria to include them in the financial statements. Likewise, it clarifies the meaning of some concepts.

2.5 Standards issued by the IASB not yet effective in Colombia

Standards and interpretations that have been issued by the International Accounting Standards Board (IASB) but not yet effective in Colombia on the date of these financial statements are disclosed below. The Group will adopt these standards on the date they become effective, according to the decrees issued by the local authorities.

2.5.1 IFRS 17 – Insurance contracts

In May 2017, the IASB issued IFRS 17, which is a new comprehensive accounting standard for insurance contracts that includes measurement, recognition, presentation, and disclosure.  Once effective, IFRS 17 will replace IFRS 4, issued in 2005. IFRS 17 applies to all kinds of insurance contracts regardless of the type of issuing entity, as well as certain guarantees and financial instruments with discretionary participation features. There are few exceptions to this standard.

The main purpose of this standard is to provide an accounting model for insurance contracts that is more useful and confidential for insurers. Unlike IFRS 4 requirements, which mainly seek to protect previous local accounting policies, IFRS 17 provides a comprehensive model for these contracts, including all relevant issues. The essence of this standard is a general model, supplemented by:

● a specific adaptation for contracts with direct participation features (Variable Fee Approach),

● a simplified approach (the Premium Allocation Approach), mainly for short-term contracts.

IFRS 17 is effective for reporting periods beginning on or after 1 January 2023, with comparative figures required. Early application is permitted, provided the entity also applies IFRS 9 and IFRS 15 on or before the date it first applies IFRS 17. This standard is not applicable to the Group

2.5.2 Amendments to IFRS 9, IAS 39 and IFRS 7 – Interest Rate Benchmark Reform

The amendments provide several exemptions that apply to all hedging relationships that are directly affected by the Interest Rate Benchmark Reform. A hedging relationship is affected if the reform results in uncertainty about the time and/or amount of cash flows based on benchmark rates of the hedged item or hedging instrument.

To date, the amendments have not been incorporated into the Colombian accounting framework by any decree. The Group is assessing the potential effect of this standard on its financial statements.

2.5.3 Amendment to IAS 1 – Presentation of Financial Statements – Classification of Liabilities as Current or Non-current

In January 2020, the IASB issued amendments to paragraphs 69 to 76 of IAS 1 to specify the requirements for classification of liabilities as current or non-current. The amendments clarify the following:

● The meaning of the right to defer settlement of a liability.

● That the right to defer settlement of the liability should be granted at the end of the period.

● That the classification is unaffected by the likelihood that the entity will exercise its right to defer settlement of the liability.

● That only if an embedded derivative in a convertible liability is itself an equity instrument would the terms of a liability not impact its classification.

15

The amendments are effective for annual reporting periods beginning on or after 1 January 2023 and must be applied retrospectively. The Group is currently assessing the impact the amendments will have on current practice and whether existing loan agreements may require renegotiation.

2.5.4 Amendment to IFRS 3 – Business Combinations – Reference to the conceptual framework

In May 2020, the IASB issued the amendments to IFRS 3 – Business Combinations – Reference to the conceptual framework. The amendments are intended to replace a reference to the Framework for the Preparation and Presentation of Financial Statements, issued in 1989, with a reference to the Conceptual Framework for Financial Reporting, issued in March 2018, without significantly changing its requirements. The Board also added an exception to the recognition principle of IFRS 3 to avoid the issue of potential ‘day 2’ gains or losses arising for liabilities and contingent liabilities that would be within the scope of IAS 37 or IFRIC 21, if incurred separately.

At the same time, the Board decided to clarify existing guidance in IFRS 3 for contingent assets that would not be affected by replacing the reference to the Framework for the Preparation and Presentation of Financial Statements.

The amendments are effective for annual reporting periods beginning on or after 1 January 2022 and apply prospectively

2.5.5 Amendment IAS 16 – Property, plant and equipment – Proceeds before intended use

In May 2020, the IASB issued Property, Plant and Equipment – Proceeds Before Intended Use, which prohibits deducting from the cost of an item of property, plant and equipment any proceeds from selling items produced while bringing that asset to the location and condition necessary for it to be capable of operating in the manner intended by management. Instead, an entity recognizes the proceeds from selling such items, and the cost of producing those items, in profit or loss.

The amendment is effective for annual reporting periods beginning on or after 1 January 2022 and must be applied retrospectively to items of property, plant and equipment made available for use on or after the beginning of the earliest period presented when the entity first applies the amendment. The amendments are not expected to have a material impact on the Group

2.5.6 Amendment to IAS 37 – Provisions, Contingent Liabilities, and Contingent Assets – Cost of Fulfilling a Contract

In May 2020, the IASB issued amendments to IAS 37 to specify which costs a company should include when assessing whether a contract will be onerous or loss-making.

According to the amendments, a ‘directly related cost approach’ shall be applied. Costs directly related to a contract to provide goods or services comprise both incremental costs and an allocation of other costs that relate directly to contract activities. General and administrative costs are not directly related to the contract and shall be excluded, unless those costs are explicitly chargeable to the counterparty under the contract.

The amendments are effective for annual reporting periods beginning on or after 1 January 2022. The Group will apply these amendments to contracts for which it has not yet fulfilled all its obligations at the beginning of the annual reporting period in which it first applies the amendments.

2.5.7 Amendment to IFRS 1 – First-time adoption of international financial reporting standards

The amendment permits a subordinate company that applies paragraph D16 (a) of IFRS 1 to measure cumulative translation differences (CTD) using amounts reported by the parent based on the date of transition to IFRS of such parent. This amendment also applies to associates or joint ventures that choose to apply paragraph D16 (a) of IFRS 1.

The amendment is effective for annual reporting periods beginning on or after 1 January 2022 with earlier adoption permitted.”

2.5.8 Amendment to IFRS 9 – Financial instruments: ‘10 per cent’ Test for Derecognition of Financial Liabilities

The amendment to IFRS 9 clarifies the fees a company includes when assessing whether the terms of a new or modified financial liability are substantially different from the terms of the original financial liability. These are only fees paid or received between the borrower and the lender, including fees paid or received by either the borrower or the lender on behalf of the other. The entity shall apply the amendment to financial liabilities that are modified or exchanged on or after the beginning of the annual reporting period in which the entity first applies the amendment.

16

An entity applies the amendment prospectively to fair value measurements on or after the beginning of the first annual reporting period beginning on or after 1 January 2022 with earlier adoption permitted. The amendments are not expected to have a material impact on the Group.

2.5.9 IAS 41 – Agriculture – Taxation of fair value measurements

As part of its 2018-2020 annual improvements to the IFRS process, the IASB issued an amendment to IFRS 41 – Agriculture. The amendment to IAS 41 removed paragraph 22 requirement to exclude cash flows from taxation when measuring the fair value of assets within the scope of IAS 41.

An entity applies the amendment prospectively to fair value measurements on or after the beginning of the first annual reporting period beginning on or after 1 January 2022 with earlier adoption permitted. The amendments are not expected to have a material impact on the Group

2.6 Significant accounting judgements, estimates and assumptions

The preparation of the consolidated financial statements requires that management use judgments, estimates, and assumptions that affect the reported amounts for revenues, expenses, assets and liabilities, and its disclosures, including contingent liabilities. Uncertainty in these judgements and estimates could result in material adjustments in the carrying value of assets or liabilities in future periods. Management expects that variations, if any, would have no significant effect on the consolidated financial statements.

The determination if an information is material is a matter of judgment and depends on the facts and circumstances involved. These estimates are based on management´s experience and its best estimate regarding present and future events, and on the best use of the information available on the date of issuance of these consolidated financial statements. Actual results may differ from these estimates but are adjusted once they are known.

In applying the accounting policies of the Group, management has exercised the following judgements that have the most significant effects on the amounts recognized in the financial statements:

● Identification of Cash Generating Units (CGUs): The CGU is the identifiable group of assets that generates cash inflows that are largely independent of the cash inflows from the sale or provision of services, arising from other assets or groups of assets.

The identification of CGUs involves significant judgment, mainly the identification of an asset’s CGU on the basis of independent cash inflows generated by the asset.

● Disbursements incurred for concessions recognized as intangible assets, financial assets, or as contract asset under IFRIC 12 (Service Concession Arrangements): Management of each of the companies that have entered into concession agreements determines the classification of the concession disbursements as intangible assets, contract assets, or financial assets, based on the characteristics of such agreements. Disbursements incurred related to concession agreements accounted for under the financial asset model are recognized as a contract asset during the construction phase and as a financial asset after construction is completed, based on the cash flows receivable under the concession and a discount rate that is reflective of a separate financing transaction between the parties under the concession contract for contract assets and for financial assets a discount rate that reflects the passage of time before payment is due and the counterparty credit risk. Disbursements incurred related to concessions under the intangible asset model are capitalized as an asset to the extent they meet the requirements of IAS 38 – Intangible assets (See Notes 3.8 and 3.9).

● Impairment of non-financial assets: Impairment exists when the carrying value of an asset exceeds its recoverable amount, which is the higher of its fair value less costs of disposal and its value in use. The fair value less costs of disposal calculation is based on available data from binding sales transactions, conducted at arm’s length, for similar assets or observable market prices less incremental costs of disposing of the asset. The value in use calculation is based on a discounted cash-flow (DCF) model and the projections of expected future cash flows that do not include restructuring activities that the Group is not yet committed to or significant future investments that will enhance the performance of the assets being tested. The recoverable amount is sensitive to the discount rate used for the DCF model as well as the expected future cash-inflows and the growth rate used for extrapolation purposes. These estimates are most relevant to goodwill and other intangibles with indefinite useful lives recognized by the Group.

● Estimation of assets and liabilities at fair value in a business combination: At the acquisition date, the Group estimated the fair value of acquired assets and assumed liabilities based on the requirements of IFRS 3. Fair value of non-financial assets included in a business combination is determined in reference to the expected cash-flows that the asset will generate based on assumptions consistent with or available to other market participants.

17

● Useful lives values of property, plant, and equipment: The estimation of useful lives of property, plant, and equipment components involves judgments and assumptions that could be affected if circumstances change. The Group reviews these assumptions annually and adjusts them prospectively if any adjustments are identified.

● Provision for legal and administrative proceedings: The Group is subject to claims relating to regulatory and arbitration proceedings, tax assessments and other claims arising in the normal course of business. Management evaluates these claims based on their nature, the likelihood that they materialize and the amounts involved, to decide on the amounts recognized and/or disclosed in the financial statements.

This analysis, which may require considerable judgment, includes the assessment of current legal proceedings brought against the Group and claims not yet initiated. A provision is recognized when the Group has a present obligation derived from a past event, it is likely that an outflow of resources of economic benefits will be required to settle the obligation, and a reliable estimate of the amount of such obligation can be made.

● Recovery of deferred tax assets: The use of professional judgment is required to determine whether deferred tax assets should be recognized in the statement of financial position. To recognize deferred tax assets, management is required to evaluate the probability that the company generates taxable income in future periods. The estimates of future taxable income are based on financial projections and the application of tax laws. Depending on how much future cash flows and taxable income significantly differ from estimates, there could be an impact on the Group’s ability to realize the net deferred taxable assets recognized on the statement of financial position.

Additionally, future changes in tax laws could limit the capacity of the Group to obtain tax deductions in future periods. Any difference between estimates and subsequent real disbursements is recorded in the year when it occurs.

● Provision for major maintenance and replacement: The Group has contractual obligations under its concession agreements in Perú to provide for major replacement and maintenance activities that are required under the contracts. Provision amounts are based on qualitative and quantitative analysis performed by the Group´s maintenance area and an estimate of disbursements for major maintenance and replacements that considers the current market prices of the components to be replaced at the time the provision is recognized. The provision amounts are recognized based on the present value of the estimated future cash outflows, based on a risk-free discount rate.  (Notes 3.9.1 and 17).

● Traffic projections for concessions: the Group´s compensation for the services provided under the concession contracts for certain Chilean concessions accounted for under the financial asset model in IFRC 12 (RUTA DEL MAIPO, RUTA DEL MAULE, RUTA DEL BOSQUE, RUTA DE LA ARAUCANÍA and RUTA DEL LOA) is determined through the estimated Present Value of Revenues (VPI) which is based on traffic studies performed by an independent entity based on GDP projections and other variables according to the concession.

● Employee benefits: The present value of defined benefit pension plans and other post-employment medical benefits and long-term benefits is based on actuarial valuations. These valuations include formulating several hypotheses which could differ from future real events, such as the determination of the discount rate, future salary increases, future pension increases, and mortality rates. Due to the complexity of the valuation, its long-term nature, and underlying hypotheses, the calculation of the defined benefit obligation is highly sensitive to changes in these hypotheses. All of them are reviewed on each closing date.

The mortality rate is based on the country’s public mortality rates. The future salary and pension increase are based on expected future inflation rates. (See Note 19).

3. Summary of significant accounting policies

3.1 Foreign currency transactions and balances

The consolidated financial statements are presented in Colombian Pesos, which is the Group’s functional currency. For each Group entity, its functional currency is determined based of the main economic environment where it operates.

The statements of profit or loss and cash flows of subsidiaries with functional currencies different from the Group’s functional currency are translated at the exchange rates on the dates of the transaction or based on the monthly average exchange rate. Assets and liabilities are translated at the closing rate, and other equity items are translated at exchange rates at the time of the transaction. All resulting exchange differences are recognized in other comprehensive income. On disposal of all or significant part of a foreign operation, the cumulative translation adjustment related to the particular foreign operation is reclassified to profit or loss.

18

Transactions in foreign currencies are initially recorded by the Group entities at their respective functional currency spot rates at the transactions date. Monetary items denominated in foreign currencies are translated at the functional currency spot rates prevailing at the reporting date. Differences arising on settlement or translation or monetary items are recognized in profit or loss, in financial results, net, except those resulting from cash flow hedges, which are recognized in other comprehensive income within equity. When the hedged item affects the financial results, exchange differences accumulated in equity are reclassified to profit or loss as part of operating results.

Non–monetary items measured at fair value that are denominated in a foreign currency are translated using the exchange rates prevailing on the date when the fair value is determined. The gain or loss arising on translation of non–monetary items measured at fair value is treated in line with the recognition of the gain or loss on the change in fair value of the item.

3.2 Classification of balances as current and non-current

The Group presents its current and non-current assets and its current and non-current liabilities as separate categories in its statement of financial position.

An asset will be classified as current when:

● the entity expects to realize the asset, or intends to sell or consume it, in its normal operating cycle;

● it holds the asset primarily for the purpose of trading;

● it expects to realize the asset within twelve months after the reporting period; or

● the asset is cash or cash equivalent (as defined in IAS 7) unless the asset is restricted from being exchanged or used to settle a liability for at least 12 months after the reporting period.

A liability will be classified as current when:

● the entity expects to settle the liability in its normal operating cycle.

● it holds the liability primarily for the purpose of trading;

● the liability is due to be settled within twelve months after the reporting period; or

● the entity does not have unconditional rights to defer settlement of the liability for at least 12 months after the reporting period.

● the conditions of a liability that could cause their settlement, at the other party’s choice, through the issuance of equity instruments, do not affect its classification. The company will classify all others as non-current liabilities.

3.3 Investments in jointly controlled entities and associates

An associate is an entity over which the Group exerts significant influence. Significant influence is the power to influence the investee’s financial and operating policy decisions but not to control it, either individually or jointly.

A Joint venture is an agreement whereby the parties exerting joint control have rights to the net assets of the joint venture. Joint control is the contractually agreed sharing of control of an agreement, which exists only when decisions about the relevant activities require unanimous consent.

Considerations used to determine the significant influence or joint control are similar to those needed to determine the control over subsidiaries. The Group’s investment in its associates and joint ventures is accounted for using the equity method.

Under the equity method, the investment in an associate or a joint venture is initially recognized at cost. The carrying value of the investment is adjusted to recognize changes in the participation of the Group in the net assets of the associate or joint venture from the acquisition date. The goodwill related to the associate or joint venture is included in the carrying value of the investment.

The statement of profit or loss reflects the Group’s participation in the results of the operations of the associate or joint venture. Any changes in other comprehensive income of these associates are presented as part of other comprehensive income for the Group. Also, when a change has been directly recognized in the equity of the associate or joint venture, the Group recognizes its participation in any changes, from time to time, in the statement of changes in equity. Unrealized gains and losses resulting from transactions between the Group and the associate or joint venture are eliminated proportional to the participation in the associate or joint venture.

The results under the equity method of the participation of the Group in the results of an associate or joint business is recognized in the income statement and represents the result after taxes of the Group’s interest in the associate or joint venture.

19

3.4 Business combinations and goodwill

The Group recognizes business combinations using the acquisition method. Identifiable assets acquired and liabilities assumed are initially measured at fair value on the acquisition date, subject to certain exceptions.

On the acquisition date, the acquirer will separately recognize the identifiable assets acquired, the liabilities assumed, any non-controlling interest in the acquiree, and any goodwill or bargain purchase resulting from the acquisition.

The company that acted as buyer will recognize the goodwill generated as an asset on the acquisition date, measured as the difference between (i) the aggregate of the consideration transferred, the amount of any non-controlling interest and in a business combination achieved in stages the acquisition-date fair value of the acquirer’s previously held equity interest in the acquiree and (ii) the net amount on the acquisition date of the identifiable assets acquired and the liabilities assumed.

Goodwill is initially measured at cost (being the excess of the aggregate of the consideration transferred and the amount recognized for non–controlling interest and any previous interest held over the net identifiable assets acquired and liabilities assumed). After initial recognition goodwill is measured at cost less any accumulated impairment loss, which cannot be reversed in subsequent periods according to IAS 36. Goodwill is not amortized but tested for impairment annually.

The acquirer will identify the acquisition date as the date on which control of the acquiree is obtained.

3.5 Inventories

Consumable inventories (spares and supplies) are recognized as inventory and then charged to expense, maintenance or project to the extent that such items are consumed.

The cost of other inventories is determined based on the weighted average cost method, which includes acquisition costs (deducting commercial discounts, rebates and other similar items), transformation, and other costs incurred to bring inventory to their current location and condition, such as transportation costs.

3.6 Property, plant, and equipment

Property, plant, and equipment are valued at their acquisition cost -historical cost- or construction cost, less depreciation and accumulated impairment losses, if any. Cost also includes:

● Import tariffs and non-recoverable indirect taxes imposed on the acquisition, after deducting trade discounts and rebates

● All costs directly related to placing the asset, in the conditions necessary for its operation in the manner intended by the management

● Borrowing costs attributable to the acquisition of a qualifying asset -an asset that requires a substantial period of time for being ready for use or sale, and from which it is expected to obtain future benefits

● The estimate of costs related to dismantling, removal and environmental rehabilitation of areas affected by the construction of the Group’s assets

Expenses for maintenance, preservation, and repair of these assets are recorded directly in income as a cost for the period in which they are incurred.

Additions and expansion, upgrading, or improvement costs are capitalized as higher value of the respective assets, if they extend their useful life, production capacity and operational efficiency, and improve the quality of services, or bring a significant reduction of costs.

20

Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets, as follows:

	Useful life
Transmission lines	63 years
Buildings	100 years
Fiber optics	25 years
Machinery and equipment	15 years
Telecommunications equipment	15 years
Furniture, office equipment, laboratory equipment	10 years
Communications equipment	10 years
Transportation, traction, and lifting equipment	10 years
Supervision and Maneuvers Center Equipment	6 years
Computer equipment and accessories	5 years

An item of property, plant and equipment and any significant part initially recognized is derecognized upon disposal (i.e., at the date the recipient obtains control) or when no future economic benefits are expected from its use or disposal. Any gain or loss arising on derecognition of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) is included in the statement of profit or loss when the asset is derecognized.

The residual values, useful lives and methods of depreciation of property, plant and equipment are reviewed at each financial year end and adjusted prospectively, if appropriate.

● Assets under construction and assembly

Assets used during the course of the construction for management, production, supply, or non-defined purposes are recorded at cost, less any recognized impairment loss. Such construction and assembly assets are classified in the corresponding categories of property, plant, and equipment when they are ready for their intended use, and the depreciation of these assets begins on that day i.e., when they are at the location and in the conditions required for operating as intended.

● Borrowing costs

Borrowing costs related to the acquisition, construction or production of a qualifying asset that requires a substantial period of time to get ready for its intended use are capitalized as part of the cost of such asset when it is probable that future economic benefits associated with the item will flow to the Group and costs can be measured reliably. Other borrowing costs are recognized as finance costs. Projects that have been suspended but that the Group intends to continue to pursue their development in the future, are not considered qualifying assets for the purpose of capitalization of borrowing costs

● Asset components

A fixed asset component is an item that can be seen as part of other asset, but due to its own characteristics, the role it plays, and the type of strategies or activities followed during its technical or service life, it may be classified as a separate asset.

Each property, plant, and equipment component shall be identified and separated from the other assets in order to depreciate them during their useful lives and make their treatment and accounting control easier. Important spare parts and permanent maintenance equipment that the company expects to use for more than one period normally comply with specifications to be classified as property, plant, and equipment. Similarly, if spare parts and assisting equipment of a fixed asset could only be used for such asset, they will be classified as part of the property, plant, and equipment.

3.7 Other assets

Includes advances to third-party service providers for the purchase of information and telecommunication technology services that are amortized during the periods in which services are received by the Group. Prepaid expenses mainly include insurance premiums, recognized in income on a straight-line basis through the contractual term.

3.8 Intangible assets

An intangible asset is recognized when the condition of being identifiable and separable is met, when the item generates future economic benefits, and when the Group is able to control such benefits.

21

Intangible assets are initially recognized at their acquisition or production cost, and then valued at their cost less their corresponding accumulated amortization and impairment losses experienced by the assets, if any.

An intangible asset is derecognized upon its disposal, or when no future economic benefits are expected. The resulting gain or loss, which is calculated as the difference between the proceeds obtained from the sale and the carrying amount of the asset, is recognized in income when the asset is derecognized.

Residual values, useful lives, and amortization methods are reviewed at each year-end and are applied prospectively, if necessary. Useful lives of intangible assets with definite lives are as follows:

	2020
Software	3 years
Licenses	10 years
Concessions	20-40 years
Rights-of-use	20-30 years
Customer list	10-15 years

● Easements

Easements are rights obtained for the use of a strip of land for the installation of a transmission line. This involves restrictions by the owner on land use and authorizations to the Group for construction, operation, and maintenance. These assets have indefinite useful lives and are not amortized.

Such intangible assets are permanent rights and although the transmission lines to which these easements are related do have a useful life of 63 years the rights do not expire and the Group can either replace the transmission lines when their useful lives end, or to use such rights for any other service related to electricity transmission and telecommunications.

● Software and licenses

Software is amortized using the straight-line method over a maximum period of three years. Licenses are amortized by the same method during periods in which it is expected to receive benefits, according to studies of feasibility for recovery.

Project studies and research charges are treated as expenses when incurred.

3.9 Concessions

The Group operates electricity transmission concessions in Colombia, Perú, Chile, Bolívia and Brazil and road concessions in Colombia and Chile under public service concession arrangements where the grantor controls or regulates the services to be provided by the concessionaire, to whom the services are provided and at what price.

Concessions that meet the above criteria and where the Group has an obligation to return the assets to the grantor or the grantor retains any residual interest over the infrastructure at the end of the concession term are accounted for under IFRIC 12 – Service concession arrangements. These include electricity concessions in Perú (except Orazul), Bolívia and Brazil and road concessions in Colombia and Chile; see Note 23.

Group assets that were constructed to operate concessions where the grantor has no residual interest over the infrastructure and the Group has no obligation to return the assets are accounted for under IAS 16. These include electricity concessions in Colombia and the Orazul concession in Perú.

3.9.1 IFRIC 12 – Services concession arrangements

Financial asset model

The concessions where the Group has a contractual right to receive money or other financial asset from the grantor in exchange for the services provided under the concession agreements are accounted for under the financial asset model. Concession infrastructure under construction is initially recorded as contract assets, in accordance with IFRS 15 and IFRIC 12, considering that the Group is entitled to consideration for performance completed to date, and, only when the construction phase ends, has the right to charge for the services provided.

For electricity concessions in Brazil, when construction is finalized, concession infrastructure assets remain as contract assets, considering that under the respective concession agreements the obligations linked to the remuneration for the construction services remain during the concession period, represented by the network construction, operation and maintenance. For the other Group concessions under this model the contract asset is reclassified as a financial asset (accounts receivable) when the performance obligations related to construction services are fulfilled, since from that point nothing more than the passage of time is necessary for the consideration to be received. The costs related to the infrastructure construction are recognized as incurred in the statement of income. The construction or upgrade services revenues are recognized in accordance with the stage of completion of the construction service, based on the costs actually incurred, including construction margin.

When adjusting the amount of consideration for the concession contract asset financing component, the Group uses the discount rate which reflects the Group’s estimation of the financing of the transmission infrastructure investments. This reflects the rate that discounts the nominal amount of the consideration to the price that the customer would pay in cash for the goods or services when (or as) they transfer to the customer. The interest rates implicit in the contract are defined at the beginning of the concessions and take into account the credit risk of the counterparties.

Intangible asset model:

Concessions where the Group does not have a contractual right to receive money or other financial asset from the grantor but has the right to charge users in exchange for the services provided are accounted for under the intangible asset model. The costs incurred by the Group to construct the concession infrastructure are recognized as intangible assets which are amortized using the straight-line over the concession term (see Notes 11 and 23). Operating and maintenance costs related to the concession are recognized in income as incurred after the concession infrastructure is ready for its intended use and the Group receives from the grantor the right to charge a fee for the services. Revenue is recognized based on services delivered and the fee stablished under the concession agreements.

The Group´s concessions in Perú (except Orazul) include a contractual obligation to perform replacements and major maintenance based on conditions established by the grantor which are accounted for as a provision for significant replacements and maintenance (Notes 2.6 and 17).

3.10Impairment of non-financial assets

The Group assesses, at each reporting date, whether there is an indication that an asset may be impaired. If any indication exists, or when annual impairment testing for an asset is required, the Group estimates the asset’s recoverable amount. An asset’s recoverable amount is the higher of an asset’s or CGU’s fair value less costs of disposal and its value in use. The recoverable amount is determined for an individual asset, unless the asset does not generate cash inflows that are largely independent of those from other assets or groups of assets. When the carrying amount of an asset or CGU exceeds its recoverable amount, the asset is considered impaired and is written down to its recoverable amount.

The recoverable amount of an asset is the higher amount of the fair value less costs of disposal or its value in use. If the recoverable amount of an asset (or of a CGU) is lower than its net carrying amount, such amount (or that of the CGU) is reduced to its recoverable amount, recognizing an impairment loss in profit or loss.

Fair value less costs of disposal is usually higher than the value in use for the asset’s in the production segment due to some significant restrictions in the estimation of future cash flows, such as: a) future capital expenses that improve the CGU performance, which could result in expected increase of net cash flows, and b) items before taxes that reflect specific business risks, resulting in a higher discount rate.

Fair value less costs of disposal is determined as the sum of the future discounted cash flows adjusted to the estimated risk. The estimations of expected future cash flows used in the assessment of impairment of the assets include estimates of futures commodity prices, supply and demand estimations, and the margins of the products.

Fair value less costs of disposal, as described above, is compared to valuation multiples and quoted prices of shares in companies comparable to the Group, in order to determine if it is reasonable.

When an impairment loss is recorded, future amortization expenses are calculated on the basis of the adjusted recoverable amount. Impairment losses may be recovered only if the reversal is related to a change in estimations used after impairment loss was recognized in previous periods. These recoveries do not exceed the carrying amount of the assets net of depreciation or amortization that would have been determined if such impairment had not been recognized.

23

Goodwill is tested for impairment annually in the last quarter and when circumstances indicate that the carrying value may be impaired.

Impairment is determined for goodwill by assessing the recoverable amount of each CGU (or group of CGUs) to which the goodwill relates. When the recoverable amount of the CGU is less than its carrying amount, an impairment loss is recognized. Impairment losses relating to goodwill cannot be reversed in future periods.

3.11Leases

At the beginning of a contract, the Group assesses whether a contract is, or contains, a lease. This situation arises if the contract transfers the right to control the use of an identified asset for a period of time in exchange for a consideration. To assess whether a contract conveys the right to control an identified asset, the regulations of IFRS 16 are used.

The Group as a lessee

On the commencement date of the lease, the Group recognizes lease liabilities to make lease payments and right-of-use assets representing the right to use the underlying asset during the lease term. The interest expense on the lease liability and the depreciation expense on the right-of-use asset are recognized separately.

In subsequent recognition, the Group makes a remeasurement of the lease obligation upon the occurrence of events such as: a) changes in the lease term, b) changes in future lease payments resulting from variations in an index or in the rate used for determine the payments. The amount of the remeasurement of the obligation will be recognized as an adjustment to the asset for the right of use.

The Group as a lessor

Leases in which the Group does not transfer substantially all the risks and rewards incidental to ownership of an asset are classified as operational. Rental income is recognized in the statement of income on a straight-line basis over the lease terms; see Note 12.

Right-of-use assets

The Group recognizes right-of-use assets on the commencement date of the lease (that is, the date on which the underlying asset is available for use) as part of its property, plant and equipment balance (see Note 10). The right-of-use assets are measured at cost, less any accumulated depreciation and impairment losses, and adjusted for any remeasurement of the lease liabilities. Right-of-use assets are amortized in a straight-line basis during the lease term. Right-of-use assets are subject to impairment assessment. 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.

Lease liabilities

At the commencement date of the lease, the Group recognizes lease liabilities measured at the present value of the lease payments to be made during the term of the lease. 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. Variable payments that do not depend on an index or rate are recognized as expenses in the period in which an event or condition indicates that the payment will occur.

In order to calculate the present value of the lease payments, the Group uses the incremental borrowing rate on the lease’s commencement date. 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 or a change in the assessment of an option to purchase the underlying asset.

Short-term leases and low-value asset leases

The Group elected to use the recognition exemptions for lease contracts that, at the commencement date, have a lease term of 12 months or less and do not contain a purchase option (short-term leases), and lease contracts for which the underlying asset is of low value (low-value assets).

24

3.12Financial assets and liabilities

3.12.1 Financial assets

The classification of financial assets at initial recognition depends on the financial asset’s contractual cash flow characteristics and the Group’s business model for managing them. With the exception of trade receivables that do not contain a significant financing component or for which the Group has applied the practical expedient, the Group initially measures a financial asset at its fair value plus transaction costs. Trade receivables that do not contain a significant financing component or for which the Group has applied the practical expedient are measured at the transaction price determined under IFRS 15.

The Group classifies its financial assets in the following categories:

● Financial assets measured at fair value through profit or loss

Financial assets are held for trading and financial assets designated at the time of the initial recognition at fair value through profit or loss. Financial assets are classified as held for trading if they are acquired to be sold or repurchased in the short term. They are recognized at their fair value and losses or profits arising at the time of re–measurement are recognized in the statement of profit or loss.

● Financial assets at amortized cost

This category is the most relevant to the Group. The Group’s financial assets at amortized cost includes trade receivables, other receivables, loans to associates, and loans to employees.

Loans and receivables are non–derivative financial assets with fixed or determinable payments that are not quoted in an active market. Loans and receivables, including trade and other receivables, are measured initially at fair value and then at amortized cost using the effective interest rate method, less impairment.

Loans to employees are initially recorded using the present value of the future cash flows, discounted at the current market rate for similar loans. If the interest rate is less than the current market rate, fair value will be less than the amount of the loan. This difference is recorded as a benefit to employees.

The Group measures financial assets at amortized cost if both of the following conditions are met:

● The asset is held within a business model with the objective to hold financial assets in order to collect contractual cash flows

● The contractual terms of the asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding

Financial assets at amortized cost are subsequently measured using the effective interest (EIR) method and are subject to impairment analysis. Gains and losses are recognized in profit or loss when the asset is derecognized, modified or impaired.

De–recognition of financial assets

The Group derecognizes a financial asset only upon the expiration of the contractual rights to the cash flows of the asset or, when it has transferred its rights to receive such cash flows or has assumed the obligation to pay the cash flows received in full without material delay to a third party and (a) it has transferred substantially all the risks and benefits inherent in the ownership of the financial asset or (b) it has neither transferred nor retained substantially all the risks and benefits of the asset, but has transferred control of the asset.

When the Group does neither transfer nor retain substantially all the risks and benefits of the asset or transfer control of the asset, the Group continues to recognize the transferred asset, to the extent of its continuing participation, and it also recognizes the associated liability.

3.12.2 Financial liabilities

Financial liabilities correspond to the financing obtained by the Group through bank credit facilities and bonds, accounts payable to suppliers and creditors.

Bonds and bank credit facilities (this is the category most relevant to the Group) are initially recognized at their fair value, net of directly attributable transactions cost. After initial recognition, interest–bearing credit facilities and bonds are subsequently measured at

25

amortized cost, using the effective interest rate (EIR) method. The effective interest method amortization is included as a financial expense in the statement of profit or loss. Amortized cost is calculated by taking into account any discount or premium on acquisition and fees or costs that are an integral part of the EIR. The EIR amortization is included as finance costs in the statement of profit or loss.

Accounts payable to suppliers and creditors are short–term financial liabilities recorded at nominal value, since it does not significantly differ from fair value.

Derecognition

A financial liability is derecognized when the obligation specified in the contract is discharged, cancelled or expires. When an existing financial liability has been replaced by another from the same lender, under substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as the de–recognition of the original liability and recognized as a new liability. The difference between the respective carrying amounts is recognized in the statement of profit or loss.

3.12.3 Derivative financial instruments and hedging operations

Financial instruments are initially recognized at fair value on the date on which a derivative contract is entered into and are subsequently remeasured at fair value. Changes in the fair value of derivatives are recognized as gains or losses in the statement of profit or loss, except for the effective portion of cash flow hedges, which is recognized in other comprehensive income and later reclassified to profit or loss when the hedge item affects profit or loss.

Changes in fair value of derivative contracts, which do not qualify or are not designated as hedges are recorded in profit or loss.

Derivatives embedded in the host contract are accounted for as separate derivatives at fair value if their economic characteristics and risks are not closely related to those of the host contracts and the host contracts are not held for trading or designated at fair value through profit or loss. These embedded derivatives are measured at fair value with changes in fair value recognized in profit or loss.

For purposes of hedge accounting, hedges are classified as:

● Cash flow hedges: hedges of the exposure to variability in cash flows attributable to a particular risk associated with all, or a component of, a recognized asset or liability or a highly probable forecast transaction, and that could affect profit or loss.

● Hedges of net investments in foreign operations.

● Fair value hedges: hedges of the exposure to changes in fair value of a recognized asset or liability or an unrecognized firm commitment, or a component of any such item, that is attributable to a particular risk and that could affect profit or loss.

At the inception of a hedge relationship, the Group formally designates and documents the hedge relationship to which it wishes to apply hedge accounting and the risk management objective and strategy for undertaking the hedge. Such hedges are expected to be highly effective in achieving offsetting changes in fair value or cash flows and are assessed on an ongoing basis to determine whether they have been highly effective throughout the financial reporting periods for which they were designated.

● Fair value hedge

The gain or loss on the hedging instrument is recognized in profit or loss, or in other comprehensive income if the hedging instrument hedges an equity instrument for which an entity has elected to present changes in fair value in other comprehensive income.

The hedging gain or loss on the hedged item shall adjust the carrying amount of the hedged item (if applicable) and be recognized in profit or loss. If the hedged item is a financial asset (or a component thereof) that is measured at fair value through other comprehensive income, the hedging gain or loss on the hedged item shall be recognized in profit or loss. However, if the hedged item is an equity instrument for which an entity has elected to present changes in fair value in other comprehensive income, those amounts remain in other comprehensive income.

● Cash flow hedges

The effective portion of the gain or loss on the hedging instrument is recognized in Other Comprehensive Income (OCI) in the cash flow hedge reserve, while any ineffective portion is recognized immediately in the statement of profit or loss.

26

The amounts previously accumulated in OCI are recognized in profit or loss when the hedged transaction affects the statement of profit or loss. If the hedged transaction subsequently results in the recognition of a non-financial item, the amount accumulated in equity is removed from the separate component of equity and included in the initial cost or other carrying amount of the hedged asset or liability.

If the hedging instrument expires or is sold, terminated or exercised without replacement or rollover, or if its designation as a hedge is revoked or when the hedge no longer meets the criteria for hedge accounting, any cumulative gain or loss previously recognized in other comprehensive income remains separately in equity until the forecast transaction occurs is recognized in the consolidated statement of profit or loss. When it is no longer expected that the initially hedged transaction will occur.

● Hedges of a net investment in a foreign operation

Hedges of a net investment in a foreign operation, including a hedge of a monetary item that is accounted for as part of the net investment, are accounted for in a way similar to cash flow hedges.

Gains or losses on the hedging instrument relating to the effective portion of the he|dge are recognized as OCI while any gains or losses relating to the ineffective portion are recognized in the statement of profit or loss. On the disposal of a foreign operation, the cumulative value of any such gains or losses recorded in equity is transferred to the statement of profit or loss.

3.12.4 Offsetting assets and financial liabilities

Financial assets and liabilities are offset are reported net in the financial statements if, and only if, there is a legally enforceable right at the closing date, requiring receiving or pay the amounts recognized at their net value, and when there is an intention to offset on a net basis to realize assets and settle liabilities simultaneously.

3.13 Fair value measurement

The fair value of an asset or liability is defined as the price that would be received when selling an asset or the price that would be paid when transferring a liability in an orderly transaction between market participants on the measurement date.

Fair value measurement assumes that the transaction to sell an asset or transfer a liability occurs in the primary market, i.e., the market with higher volume and level of activity for the asset or liability. In the absence of a primary market, it is assumed that the transaction takes place in the most advantageous market the company has access to, that is, the market that maximizes the amount to be received when selling the asset or the market that minimizes the amount that would be paid to transfer the liability.

To determine the fair value, the Group uses valuation techniques that are appropriate to the circumstances and on which there are sufficient data for measuring, maximizing the use of relevant observable input data and minimizing the use of unobservable input data.

Taking into account the hierarchy of input data used in valuation techniques, assets and liabilities measured at fair value are classified at the following levels:

● Level I: quoting prices (unadjusted) in active markets for identical assets or liabilities.

● Level II: valuation techniques for which the data and variables that have a significant effect on the determination of the fair value recorded are observable, either directly or indirectly.

● Level III: internal valuation techniques, using company estimated variables not observable for the asset or liability (there is no market information observable).

When measuring fair value, the company considers the characteristics of the asset or liability, in particular:

● For non-financial assets, an estimation of the fair value considers the capacity of a market participant to generate economic benefits by making the highest and best use of the asset, or by selling it to other market participant that would make the highest and best use of the same.

● For liabilities and own equity instruments, the fair value entails that the liability will not be settled, and the equity instrument will not be canceled, nor otherwise will be extinguished on the measurement date. The fair value of the liability reflects the effect of the default risk, i.e., the risk that a company does not meet an obligation, which includes but is not limited to the company’s own credit risk.

● In the case of financial assets and liabilities with offset positions at market risk or counterpart credit risk, the fair value is measured on a net basis that is consistent with the way market participants would price the net exposure to risk on the measurement date.

27

3.14 Provisions

Provisions are recognized when the Group has a present obligation -legal or implicit- as the result of a past event; it is probable that a resource outflow is needed to settle such obligation, and a reliable estimate regarding the amount of the obligation can be made.

The amount recognized as provision should be the best estimate of the disbursement required to settle the present obligation at the end of the period that is reported, considering the corresponding risks and uncertainties. When a provision is measured using the cash flows estimated to settle said obligation, its carrying amount reflects the present value of that cash flow (when the effect of the value of money over time is material).

Certain contingent conditions may exist on the date of issuance of the statement of financial position. These may result in a loss for the companies and will only be resolved in the future, when one or more events occur or may occur; such contingencies are estimated by the management and its legal advisors. The estimation of loss contingencies necessarily involves an exercise of judgement and it is a matter of opinion.

If the estimation of the contingency indicates that it is probable that a material loss will occur and the amount of the liability can be estimated, then it is recorded in the statement of financial position. In addition, if the estimation indicates that a potential loss is not probable and its amount is known, or is probable but the amount of the loss cannot be estimated, then the nature of the contingency is disclosed in a note to the statement of financial position, with an estimate of the potential range of loss. Loss contingencies estimated as remote are not disclosed.

3.15 Income tax

Income tax expense for the period comprises current and deferred income tax. Tax assets and liabilities are measured at the amounts expected to be recovered from or paid to tax authorities and the income tax expense is recognized in income, except when it is related to items recognized directly in equity, in which case it is recognized in equity.

The tax rates and tax laws used to compute the tax amounts are those that are enacted or substantively enacted at the reporting date in the countries where the Group operates and

generates taxable income.

3.15.1 Current tax

The current tax payable is based on taxable income generated in the year. Taxable income differ from profit before taxes in the income statement due to permanent differences related to income or expense items that are taxable or deductible, and due to temporary differences related to income or expense items that are taxable or deductible in future years. The current tax liability is calculated by using tax rates in force at the end of the period.

The Group periodically evaluates positions taken in tax returns with respect to situations in which tax laws are subject to interpretation and, when appropriate, recognize provisions for the amounts they expect to pay to tax authorities.

3.15.2 Deferred tax

Deferred tax is recognized on temporary differences between the carrying amounts of assets and liabilities included in the statement of financial position and the corresponding tax bases used for determining taxable income. Deferred tax assets and liabilities are offset if there is a legally enforceable right to offset the assets and liabilities by current tax and are related to income taxes applied by the same tax authority on the same taxable company.

Deferred tax assets are recognized for all the deductible temporary differences, including tax losses, to the extent it is more likely than not that there is expected future taxable income against which the deductible temporary differences and the carry forward of unused tax credits and unused tax losses can be recovered.

The carrying amount of deferred tax assets is reviewed on each closing date and reduced to the extent that it is no longer likely that there will be sufficient taxable income available to allow the use of all or part of the deferred tax asset. The deferred tax related to items recorded directly in equity is recognized in equity.

The Group offsets deferred tax assets and deferred tax liabilities if and only if it has a legally enforceable right to set off current tax assets and current tax liabilities and the deferred tax assets and deferred tax liabilities relate to income taxes levied by the same taxation

28

authority on either the same taxable entity or different taxable entities which intend either to settle current tax liabilities and assets on a net basis, or to realise the assets and settle the liabilities simultaneously, in each future period in which significant amounts of deferred tax liabilities or assets are expected to be settled or recovered.

3.16 Employee benefits

Employee benefits include all compensations to employees and former employees related to the provision of services to the entity. These are salaries, short-term and long-term benefits, termination benefits and post-employment benefits.

3.16.1 Current benefits

Obligations regarding current employee benefits are recognized as expenses as the related service is provided. Employment obligations are adjusted at the end of each period, based on legal provisions and labor agreements in force.

This benefit is recognized when there is a current legal or implicit obligation to make a payment as a result of a service provided by the employee in the past and at the time the obligation can be estimated reliably. The obligation is recognized by the amount expected to be paid within the next year after the cut-off.

3.16.2 Long term employee benefits

Some Group companies grant their employees benefits associated with their time of service, such as quinquennium (seniority premium and five-year period payments).

The fair value of the plan assets is deducted from the present value of the benefit obligation when determining the deficit or surplus. The calculation is performed annually supported by certified independent actuaries, based on the projected credit unit method. Any actuarial gain or loss is recognized in income for the corresponding period.

3.16.3 Post-employment benefits

● Defined contribution plans

The defined contribution plan is a post-employment benefit by which the Group pays fixed contributions to a pension fund, and by which it has no legal obligation to pay additional amounts. The obligations for payment of contributions to defined benefit pension plans are recognized as employment benefit expense in income for the periods in which employees provide the services.

● Defined benefit plans

In the case of defined benefit plans, the obligation and the cost of such benefits is determined by using the projected unit credit method, based on independent actuarial calculations performed on an annual basis.

The liability recognized in the statement of financial position regarding defined benefit pension plans is the present value of the defined benefit obligation on the date of the statement of financial position, less the fair value of the plan assets. The present value of the defined benefit obligation is determined by discounting the estimated cash outflow.

Actuarial gains and losses arising from adjustments based on experience and changes in actuarial assumptions are charged or credited in other comprehensive income for the period in which they arise.

Past service costs are recognized immediately in income, unless changes in the pension plan are conditioned to the fact that the employee continues providing services for a specific period −the period granting the right−. In this case, the past service costs are amortized by the straight-line method during the period that grants the right.

● Other post-employment obligations

Some Group companies grant their retired employees benefits such as complementary health plan, health assistance, education assistance and calamity loan, after the employment relation. The right to access these benefits depends on the conditions defined in individual and collective agreements.

29

The obligation and the cost of such defined benefit plans are determined by the projected unit credit methodology on an annual basis. Actuarial gains and losses arising from changes in actuarial assumptions are charged or credited in the statement of comprehensive income for the period in which they arise.

3.16.4 Termination benefits

These benefits are determined by using the Projected Unit Credit method, with actuarial valuations conducted at the end of each annual period being reported. The new measurement, which includes actuarial gains and losses, is immediately reflected in the statement of financial position, charged or credited to other comprehensive income for the period in which it is incurred.

3.17 Onerous contracts

Present obligations arising from an onerous contract are recognized as a provision when the unavoidable costs of meeting the obligations of the contract exceed the economic benefits expected to be received from it. On the date of the statements of financial position, the Group has no provisions for onerous contracts.

3.18 Recognition of revenues, costs, and expenses

Revenues, costs and expenses are recorded on an accrual basis.

3.18.1 Revenues from contracts with customers

The Group recognizes revenues from ordinary activities for the transfer of goods or services to customers in exchange for an amount that reflects the consideration to which the Group expects to receive in exchange for those goods or services.

Revenues are recognized only when all the following criteria are met:

Step 1: Identify the contract with the customer.

Step 2: Identify the performance obligations in the contract.

Step 3: Determine the price of the transaction.

Step 4: Allocate the price of the transaction to the performance obligations in the contract.

Step 5: Recognize ordinary revenues when (or as) the entity satisfies a performance obligation.

The following criteria apply for the recognition of revenues:

● Revenues from contracts with customers for electricity transmission and other associated services

Revenues from electricity transmission services are recorded when performance obligations are met based on the underlying conditions in the contracts which includes the requirements established by the electricity market regulators in the countries in which the Group operates. This is generally achieved when the performance obligations agreed with the regulatory entities are met, considering the execution period and service quality standards established under the contracts.

● Revenues from concession arrangements

Concession revenues accounted for under IFIRC 12, applicable to electricity transmission companies in Brazil, Bolivia, Peru, and road concession companies in Colombia and Chile are measured at the fair value of the consideration received or receivable, taking into account the payment conditions defined in the contracts. The following specific criteria must be met to recognize revenues in accordance with the application of IFRIC 12:

● Construction services. Revenues and costs from project construction services are recognized in the comprehensive income statement, according to the completion percentage method for those projects on the date of statement of financial position which includes an estimated profit margin determined based on macroeconomic characteristics and conditions of the project and the flows estimated from cash collections in relation with cash flows estimated for the construction of infrastructure.

● Operation and maintenance services. Revenues from operation and maintenance services to third-parties are recognized as the service is delivered based on the performance obligations established in the contracts.

30

● Financial returns of concessions recorded as financial asset or contract asset. The companies that recognized their concessions as financial asset or contract asset according to IFRIC 12, recognize interests of the account receivable credited to income, by using the effective interest rate method.

● Dividend income

Dividends are recognized once shareholders’ rights to receive the payment have been established –provided that the economic benefits will flow to the company and ordinary revenues can be measured reliably. Dividends are accrued when approved by the companies over which the Group has no control, joint control, or significant influence.

● Interest income

Interest income is recognized when it is probable that the Group will receive economic benefits associated with the transaction. Interest income is recognized on an accrual basis, by reference to the outstanding principal and the effective interest rate applicable, which is the discount rate that exactly matches the cash flow receivable or payable estimated throughout the expected life of the financial instrument to the net carrying amount of the financial asset on initial recognition.

3.19 Basic and diluted earnings per share

Earnings per share is calculated by dividing the income attributable to the controlling shareholders of ISA, by the weighted average of common shares outstanding in the year.

3.20 Distribution of dividends

Dividends to shareholders are recognized as a liability in the financial statements of Group companies ISA in the period in which the Shareholders’ Meeting approves such dividends, or when the corresponding obligation is in place according to the applicable legal provisions or policies established by the Shareholders’ Meeting.

3.21 Capital stock

Common shares are classified in equity. Incremental costs directly attributable to the issuance of new shares or options are shown in equity as a deduction from the amount received, net of taxes.

The repurchase of ISA´s shares is recognized directly in equity at their acquisition cost and the difference between this amount and the nominal value of the shares is recognized as additional paid-in capital. Rights are suspended for own shares reacquired and, therefore, they do not take part in the distribution of dividends.

ISA is listed in the Colombia Stock Exchange.

3.22 Additional paid-in capital

Corresponds to the difference between the amounts paid for the shares issued and their nominal value, and the difference between the issuance value of the shares and their re-acquisition costs for shares repurchased.

3.23 Related parties

Related parties are considered those in which one party has the ability to control, or has joint control of the other, or exercises significant influence over the other party in making financial or operational decisions or is a member of key management personnel (or close relative of a member). The Group considers related parties to be associates, joint ventures, key management executives and key management personnel of the Group´s controlling shareholder.

3.24 Information by business segment

The Group presents the information related to its business segments in its consolidated financial statements in accordance with paragraph 4 of IFRS 8 – Operation segments.

The operations of the Group are performed through three business segments: 1) Electric power, 2) Road concessions and 3) Telecommunications and information technology. Segments are determined based on management objectives and corporate strategic plans, considering that these businesses: (a) are engaged in different commercial activities, which generate sales revenue and incur costs

31

and expenses; (b) the operational results are revised regularly by the Group’s Governance that makes operational decisions to allocate resources to the various segments and assess their performance; and (c) there is differentiated financial information available. Internal transfers represent sales to inter–company segments and are recorded and presented at market prices.

See information by segments in Note 30.

3.25 Other liabilities and deferred revenue

Other liabilities are recognized at the amounts payable according to the underlying commitments, including the effect of amortized cost when payment obligations are fulfilled in the long-term. Deferred revenue is recognized based on the amounts received, reflecting the obligation assumed to deliver services in the future, and is recognized as revenues in the statement of comprehensive income as the performance obligations are met.

Financial instruments - Liquidity surplus

The Group invests it´s liquidity surplus in financial instruments with the objective to keep them until their due date; therefore, it is normally not exposed to interest rate risk.

15.2 Exchange rate risk

The Group is exposed to exchange rate risk arising mainly from its investments in foreign entities and from assets and liabilities indexed in foreign currencies.

In situations where there is no natural hedge that could compensate the exchange rate risk, the Group may enter into financial hedging operations to cover this risk.

Hedge operations for financial risks are considered as mitigation tools for market risk.

As part of its Market Risk hedging strategy (Exchange Rate, Interest Rate, Price), the Group acquires derivative financial instruments such as forwards and swaps at the best available conditions in each market (see note 13.3).

15.3 Credit and counterparty risk

15.3.1 Credit risk (customers):

This risk is related to the potential default of counterparties for services rendered by Group companies, financial institutions in which it keeps investments and contracts financial instruments. In this regard, the majority of the Group´s businesses is highly regulated and contractual measures exists that reduce such risk.

The Group performs a continuous analysis of the financial strength of its counterparties, by classifying them according to their risk level and financial guarantees in the event of a default of payments. Similarly, the Group continuously monitors national and international market conditions for early alerts of major changes that may have an impact on the timely payment of obligations from customers.

For the receivables that are considered exposed to credit risk, the Group makes individual analysis of each customer’s situation to determine the value of impairment to recognize in financial statements

15.3.2 Credit risk - surplus liquidity:

This risk is mainly mitigated through the selection of financial institutions of renowned strength and positive risk ratings given by locally or internationally authorized agencies. In addition, the Group uses allocation models that analyze both quantitative (financial indicators) and qualitative (risk grading) variables when investing its surplus liquidity.

44

As of December 31, 2020, no financial institutions where the Group manages its excess liquidity presented any indicators related to this risk.

15.4 Liquidity risk

The Group defines liquidity risk as the potential lack of capacity to obtain enough funds for the fulfillment of its obligations, without incurring in unacceptably high costs. The Group constantly monitors its short-term cash flow needs, which permits liquidity needs to be identified timely.

On the other hand, the Group maintains tools to achieve additional liquidity, such as the issuing of commercial papers and credit facilities with local and foreign entities that enable the fulfillment of temporary requirements for funds when so required.

- The income tax rate applicable to national companies and foreign entities will be 32% for the year 2020, 31% for the year 2021 and 30% for the year 2022 and subsequent years.

- For the years 2019 and 2020, the presumptive income rate will be 1.5% and 0.5%, respectively, of the taxpayer’s net equity from the immediately previous year. From 2021 the applicable tax rate will be 0%.

- The income tax for tax free trade zone users will be 20%. If the company located in the free zone has a Legal Stability Agreement (hereinafter LSA), the income tax rate will continue to be 15% during the term of said contract.

- For fiscal year 2020, the Group had subsidiaries that were subject to a 32% income tax rate.

- The tax depreciation percentages are adjusted based on the table established in Law 1819 of 2016.

46

- Tax losses generated as of January 1, 2017 may be offset against ordinary net income obtained in the following 12 taxable years.

- Following the Article 290 of Law 1819 of 2016, any excess between estimated income reported and CREE that has not yet been offset may be offset in accordance to the formula provided for this purpose in said article and subject to the term established in Article 189 of the Colombian Tax Code.

A 7.5% withholding is established for dividends distributed to companies domiciled in Colombia and 10% when paid to non-residents.

VAT paid for the acquisition, construction or formation and importation of capital assets of any industry may be deducted from the income tax. Regarding assets ready for use, the discount may only beapplied from the moment the asset is puto in operation and depreciation begins

Statute of limitations of tax returns in Colombia

By general rule, the statute of limitations for the income tax return corresponds to 3 years counted as from the due date to file the return or the filing date, when these have been lately filed. Returns filed by taxpayers that have made transactions, subject to the transfer pricing regulations, have a five-year statute of limitations, for the tax returns that are filed as of January 1, 2020.

For tax returns with favorable balances, the statute of limitations will be 3 years as of the filing date of the request for refunds or offsetting.

For tax returns in which tax losses are carried forward, the statute of limitations will be 6 years (5 years from 2020) counted as of their filing date.

With respect to tax returns where tax losses are calculated, the statute of limitations will be 12 years and if the losses are carried forward within the last 2 years of the 12–year period, the statute of limitations will be extended up to 3 additional years from the year of offsetting.

In addition, to determine the income tax, the following must be considered:

● For fiscal years 2020, 2019 and 2018, the Group had foreign subsidiaries that were subject to statutory income tax rates ranging from 27% to 34%.

● On June 27, 2008, ISA and the – Colombian Ministry of Mines and Energy- signed a legal stability agreement for the electricity transmission activity for a 20-year period. This agreement basically provided for stabilization of income tax regulations, including the income tax rate, deduction of the inflationary element of financial expenses, special deduction of 40% for new investments in real productive fixed assets, tax discount by VAT paid at import of machinery for electricity transmission and presumptive income as 3% of net assets, as well as the time limit of the equity tax.

This agreement ensures that in the event of adverse changes to the rules stabilized in the agreement, those rules will continue to apply during the term thereof.

19.1 Post-employment benefits

19.1.1 Retirement pensions

The Group sponsors defined benefit retirement plans in Colombia (ISA, ISA TRANSELCA, and XM) and Brazil (ISA CTEEP)

The present value of the pension obligation as of December 31, 2020, was calculated based on actuarial studies in accordance with IAS 19 based on the projected credit unit method.

According to this method, benefits are attributed to periods in which the obligation to provide them is created by directly applying the formula of the plan benefit, based on the service at the time of the valuation. When the benefit is based on compensation or salary or

50

salary increases, they are applied until the date on which the participant is expected to end the service. However, if the service in recent years leads to significant additional benefits related to previous years, benefits are linearly attributed from the date when service by the employee entitles to benefits under the plan, until such date when subsequent services lead to no additional material amount of benefits under the plan.

The primary actuarial variables used in the valuation were:

32 COVID-19 Implications

The Covid-19 outbreak was first reported in late 2019 in China. Subsequently, taking into account the level of expansion, the World Health Organization (WHO) declared the outbreak as a pandemic on March 11, 2020. Said status is maintained to the date of these financial statements.

Many countries have undertaken various public health measures to control the spread of COVID-19, including mandatory quarantines, forced economic shutdowns and travel restrictions, as well as economic measures to mitigate the impacts of such public health policies on their respective national economy.

The Covid-19 pandemic has also caused significant volatility in financial markets around the world. While governments have announced aid packages to the most affected people and taken macroeconomic measures to face the crisis, the COVID-19 pandemic has disrupted economies worldwide.

On March 17, 2020, Colombia Government, through Legislative Decree 417 of 2020, declared a 30-day state of national emergency in light of the health and economic crisis caused by the outbreak of COVID-19. On May 6, 2020, the Government declared a state of emergency for an additional 30 days. For the rest of 2020, the National Government and local authorities implemented sectored lockdowns, and partial closures of commerce and not essential economic activities according to the number of new cases of infected population and hospital capacity. The Government also has implemented other economic and public health measures to address the crisis, including (i) border closure for all non-citizens and non-residents; (ii) short term and low interest loans for all types of agricultural producers; (iii) payroll subsidies for companies and credit lines for different sectors of the economy; (iv) incentivizing working from home and a mandatory work from home order for 80% of Government employees and (v) reduction in the prices of gasoline, among others.

63

This situation did not generate any significant impact to the Group´s operations, particularly due to the fact that the businesses operated by ISA are long-term in nature and have predictable, regulated revenues and insignificant demand risk hence were not impacted as compared other economic sectors that experienced severe impacts and disruption of normal operations.

Nonetheless, the Group has set up a permanent crisis committee, which has taken the following measures, among others, to protect the integrity of its employees and its stakeholders: (i) permanent monitoring of the health conditions of its own and third party employees, (ii) follow-up on the pandemic’s progress in the regions where we are present, (iii) implementation of working from home policies and procedures for employees in Latin America who do not need to be on site (people who should return to the facilities must not have a COVID-19 infection vulnerability condition), (iv) the suspension of all national and international travels and, (v) the suspension of visits from external parties in the company´s headquarters. These measures also include the activation of business contingency plans, which comprise alternate control centers and distributed operation, distributed and alternated work groups, training of reserve staff to operate critical positions at control centers, reinforcement in the disinfection of spaces, supply of personal protection equipment, reinforcement in team training on critical processes, and modernization of facilities to mitigate contagion.
