BASIS OF PRESENTATION OF THE CONSOLIDATED FINANCIAL STATEMENTS
Basis of Presentation of the Consolidated Financial Statements	2. BASIS OF PRESENTATION OF THE CONSOLIDATED FINANCIAL STATEMENTS 2.1. Accounting principles The consolidated financial statements of Enel Chile as of December 31, 2022, approved by its Board of Directors at its meeting held on April 26, 2023, have been prepared in accordance with International Financial Reporting Standards (IFRS), as issued by the International Accounting Standards Board (IASB). These consolidated financial statements reflect faithfully the financial position of Enel Chile and its subsidiaries as of December 31, 2022 and 2021, and the results of operations, changes in equity and cash flows for the years ended December 31, 2022, 2021 and 2020, and the related notes. These consolidated financial statements have been prepared under going concern assumptions on a historical cost basis except when, in accordance with IFRS, those assets and liabilities are measured at a fair value. Appendix 1 – Detail of Assets and Liabilities in Foreign Currency; Appendix 2 – Additional Information Circular No. 715 of February 2, 2012; Appendix 2.1 – Supplementary Information on Trade Receivables; Appendix 2.2 – Estimates of Sales and Purchases of Energy, Power and Toll and Appendix 3 – Detail of Due Dates of Payments to Suppliers, form an integral part of these consolidated financial statements. 2.2. New accounting pronouncements a) The following accounting pronouncements have been adopted by the Group effective beginning on January 1, 2022: ​ ​ ​ Amendments and Improvements Mandatory application for annual periods beginning on or after: ​ ​ ​ Amendments to IFRS 16: COVID-19 - Related Rent Concessions Beyond June 30, 2021 ​ April 1, 2021 ​ ​ ​ Amendments to IFRS 3: References to the Conceptual Framework ​ January 1, 2022 ​ ​ ​ Amendments to IAS 16: Proceeds Before Intended Use ​ January 1, 2022 ​ ​ ​ Amendments to IAS 37: Onerous Contracts - Cost of Fulfilling a Contract ​ January 1, 2022 ​ ​ ​ Annual improvements to IFRS: 2018-2020 Cycle ​ January 1, 2022 ​ Amendments to IFRS 16: “COVID-19-Related Rent Concessions after June 30, 2021” Because of the continued impact of the COVID-19 pandemic, the IASB issued an amendment to IFRS 16 “Leases” on March 31, 2021, that extended by one year the period of application of the practical expedient that helps lessees to account for rental concessions linked to COVID-19. With these amendments, the IASB extended the practical expedient to rent concessions that reduce lease payments originally due on or before June 30, 2022. The amendment is effective for annual periods beginning on or after April 1, 2021, retrospectively, recognizing the cumulative effect of initially applying the amendment as an adjustment to the opening balance of retained earnings (or another component of equity, as appropriate) at the beginning of the annual reporting period in which the lessee first applies the amendment. Earlier application is permitted, even for financial statements that have not been authorized for publication as of March 31, 2021. Enel Chile has decided not to apply these amendments early. The adoption of these amendments generated no impacts on the Group’s consolidated financial statements on the date of initial application. Amendments to IFRS 3: “References to the Conceptual Framework” On May 14, 2020, the IASB issued a package of limited-scope amendments, including amendments to IFRS 3 “Business Combinations”. The amendments update references to the Conceptual Framework issued in 2018, in order to determine an asset or a liability in a business combination. In addition, the IASB added a new exception to IFRS 3 for liabilities and contingent liabilities, which specifies that, for certain liabilities and contingent liabilities, within the scope of IAS 37 “Provisions, Contingent Liabilities and Contingent Assets”, or IFRIC 21: “Levies”, an acquirer applying IFRS 3 should refer to these standards, instead of the 2018 Conceptual Framework. Without this exception, an entity would have recognized certain liabilities in a business combination that would not be recognized in accordance with IAS 37. The amendments are applicable prospectively to business combinations with acquisition dates beginning on or after January 1, 2022. The adoption of these amendments generated no impacts on the Group’s consolidated financial statements on the date of initial application. Amendments to IAS 16 “Proceeds before Intended Use” As part of the package of limited-scope amendments issued in May 2020, the IASB issued amendments to IAS 16 “Property, Plant and Equipment”, which prohibit a company from deducting from the cost of an item of property, plant and equipment amounts received from selling items produced while the company is preparing the asset for its intended use. Instead, the company will recognize such proceeds from sales and related costs in profit or loss for the period. The amendments also clarify that an entity is “testing whether an asset operates properly” when it assesses the technical and physical performance of the asset. These amendments are applicable to annual reporting periods beginning on or after January 1, 2022. Early application is permitted. The amendments will be applied retrospectively, but only from the beginning of the first period presented in the financial statements in which the entity applies the amendments for the first time. The accumulated effect of initial application of the amendments will be recognized as an adjustment to the opening balance of retained earnings (or another equity component as applicable) at the beginning of the first period reported . The adoption of these amendments generated no impacts on the Group’s consolidated financial statements on the date of initial application. Amendments to IAS 37 “Onerous Contracts: Cost of Fulfilling a Contract” The third standard amended by the IASB in the package of limited-scope amendments issued in May 2020 was IAS 37 “Provisions, Contingent Liabilities and Contingent Assets”. The amendments specify which costs a company should include when evaluating whether a contract is onerous. In this sense, the amendments clarify that the direct cost of fulfilling a contract comprises both the incremental costs of fulfilling this contract (for example, direct labor and materials), as well as the allocation of other costs that are directly related to compliance with the contracts (for example, an allocation of the depreciation charge for an item of property, plant and equipment used to fulfill the contract). These amendments are applicable to annual reporting periods beginning on or after January 1, 2022. Early application is permitted. Companies must apply these amendments to contracts for which all obligations have still not been fulfilled at the beginning of the annual reporting period in which the amendments are applied for the first time. They do not require restatement of comparative information. The accumulated effect of initially applying the amendments will be recognized as an adjustment to the opening balance of retained earnings (or another equity component as applicable) at the date of initial application. The adoption of these amendments generated no impacts on the Group’s consolidated financial statements on the date of initial application. Annual Improvements to IFRS: 2018-2020 Cycle On May 14, 2020, the IASB issued a number of minor amendments to IFRSs, in order to clarify or correct minor issues or overcome possible inconsistencies in the requirements of certain standards. The amendments with potential impact on the Group are the following: - IFRS 9 “Financial Instruments”: clarifies that for the purpose of the 10% test for derecognition of financial liabilities, when determining commissions paid net of commissions received, the borrower must only consider the commissions paid or received between the borrower and the lender. These improvements are applicable to annual reporting periods beginning on or after January 1, 2022. Early application is allowed. Entities must apply these amendments to financial liabilities that are modified or exchanged at the beginning of the annual reporting period, in which the amendments are applied for the first time. - Examples accompanying IFRS 16 Leases: amendment of illustrative example 13, in order to eliminate a possible confusion regarding the treatment of lease incentives. The example included as part of its background information, a reimbursement from the lessor to the lessee, related to leasehold improvements. Since the example was not sufficiently clear as to whether the reimbursement complied with the definition of a lease incentive, the IASB decided to eliminate from the illustrative example any reference to this reimbursement, thus avoiding any possibility of confusion. The adoption of these amendments generated no impacts on the Group’s consolidated financial statements on the date of initial application. ​ b) Accounting pronouncements effective beginning on or after January 1, 2023 As of the date of issuance of these consolidated financial statements, the following accounting pronouncements had been issued by the IASB, but their application was not mandatory: ​ ​ ​ Amendments and Improvements Mandatory application for annual periods beginning on or after: ​ ​ ​ IFRS 17 Insurance Contracts ​ January 1, 2023 ​ ​ ​ Amendments to IAS 1 and Practice Statement No. 2: Disclosure of Accounting Policies ​ January 1, 2023 ​ ​ ​ Amendments to IAS 8: Definition of Accounting Estimates ​ January 1, 2023 ​ ​ ​ Amendments to IAS 12: Deferred Taxes Relating to Assets and Liabilities Arising from a Single Transaction ​ January 1, 2023 ​ ​ ​ Amendments to IFRS 16: Lease Liability in a Sale and Leaseback ​ January 1, 2024 ​ ​ ​ Amendments to IAS 1: Classification of Liabilities as Current or Non-Current and Non-Current Liabilities with Covenants ​ January 1, 2024 ​ IFRS 17 “Insurance Contracts” ​ On May 18, 2017, the IASB issued IFRS 17 Insurance Contracts, with the objective of helping investors and others to gain a better understanding of the risk exposure, profitability and financial position of insurance companies. The new standard is applicable to all types of insurance contracts, regardless of the type of entity that issuing them. This standard is also applicable to certain guarantees and financial instruments with specific discretionary participation features. IFRS 17 replaces IFRS 4 Insurance Contracts, which was introduced as an interim standard in 2004, to solve comparison issues created by the latter. IFRS 17 requires that all insurance contracts be accounted for consistently. Insurance obligations will be accounted for at present value, rather than at historical cost. The information will be updated periodically, thereby providing more useful information to financial statement users. In December 2021, the IASB amended IFRS 17 to add a "classification overlay" transition option to address possible accounting mismatches between financial assets and insurance contract liabilities in the comparative information presented on the initial application of IFRS 17. This standard is applicable retrospectively, with certain exceptions, for annual periods beginning on or after January 1, 2023. The adoption of these amendments generated no impacts of this amendment and Management has concluded that its implementation does not have a significant impact on the Group’s consolidated financial statements. Amendments to IAS 1 and IFRS Practice Statement No. 2: “Disclosure of Accounting Policies” On February 12, 2021, the IASB issued limited-scope amendments to IAS 1: Presentation of Financial Statements and IFRS: Practice Statement No. 2 Making Materiality Judgements. This related to the final stage of its materiality improvement work, in order to help entities with their accounting policy disclosures. The aim was to provide more useful information to investors and other primary users of the financial statements. Amendments to IAS 1 require entities to disclose their material information on the accounting policies rather than their significant accounting policies. The amendments to IFRS Practice Statement No. 2 provide guidance on how to apply the concept of materiality to accounting policy disclosures. The amendments are effective for annual periods beginning on or after January 1, 2023. The adoption of these amendments generated no impacts of this amendment and Management has concluded that its implementation does not have a significant impact on the Group’s consolidated financial statements. Amendments to IAS 8: “Definition of Accounting Estimates” On February 12, 2021, the IASB issued limited-scope amendments to IAS 8: “Accounting Policies, Changes to Accounting Estimates and Errors.” The aim was to clarify how companies should distinguish between changes to accounting policies and changes to accounting estimates, in order to reduce diversity in practice. This distinction is important because accounting estimate changes only apply prospectively to future transactions and other future events. In addition, accounting policy changes generally apply retrospectively to past transactions and other past events. The amendments are effective for annual periods beginning on or after January 1, 2023 and will be applied prospectively to changes in estimates and accounting policies that occur from the beginning of the first year in which the entity applies the amendments. The adoption of these amendments generated no impacts of this amendment and Management has concluded that its implementation does not have a significant impact on the Group’s consolidated financial statements. Amendments to IAS 12: “Deferred Taxes related to Assets and Liabilities Arising from a Single Transaction” On May 7, 2021, the IASB issued specific amendments to IAS 12: Income Taxes, with the aim of clarifying how companies should account for deferred taxes on transactions, such as leases and decommissioning obligations. In certain circumstances, companies are exempt from recognizing deferred taxes when they recognize assets or liabilities for the first time. Previously, there was some uncertainty about whether the exemption applied to transactions, such as leases and decommissioning obligations. The amendments clarify that the exemption is not applicable to transactions that at the time of initial recognition give rise to equal taxable and deductible temporary differences and accordingly, companies are required to recognize deferred taxes on such transactions. The amendments are effective for annual periods beginning on or after January 1, 2023. The adoption of these amendments generated no impacts of this amendment and Management has concluded that its implementation does not have a significant impact on the Group’s consolidated financial statements. Amendments to IFRS 16 “Lease Liability in a Sale and Leaseback” On September 22, 2022, the IASB issued amendments to IFRS 16 Leases, in order to clarify how a lessee-seller measures a leaseback operation after the transaction date in order to meet the requirements of IFRS 15 Revenue from Contracts with Customers, in order to be recorded as a sale. These amendments apply to annual periods beginning on or after January 1, 2024, and early adoption is permitted. The amendments will be applied retrospectively to leaseback transactions performed after the initial application of IFRS 16. Management is assessing the potential impact of the application of these amendments on the Group's consolidated financial statements. Amendments to IAS 1 “Classification of Liabilities as Current and Non-Current” and “Non-Current Liabilities with Covenants” On January 23, 2020, the IASB issued limited-scope amendments to IAS 1: Presentation of Financial Statements, in order to clarify how to classify debt and other liabilities as current or non-current. The amendments clarify that a liability is classified as non-current if the entity has, at the end of the reporting period, the substantial right to defer settlement of the liability during at least 12 months. The classification is not affected by the expectations of the entity or by events after the reporting date. The amendments include clarification of the classification requirements for debt that a company could settle by converting it to equity. The amendments only affect the presentation of liabilities as current and non-current in the statement of financial position, not the amount and timing of their recognition, or the related disclosures. However, they could lead to companies reclassifying certain current liabilities to non-current and vice versa. This could affect compliance with covenants in the debt agreements of companies. In addition, on October 31, 2022, the IASB issued new amendments to IAS 1, with the aim of improving the information that companies provide on long-term debt with covenants. The amendments also respond to comments from stakeholders on the classification of debt as current or non-current when applying the requirements issued in 2020. The amendments are effective for annual periods beginning on or after January 1, 2024. Early adoption is permitted. Management is assessing the potential impact of the application of these amendments on the Group’s consolidated financial statements. 2.3. Responsibility for the information, judgments and estimates provided The Company’s Board of Directors is responsible for the information contained in these consolidated financial statements and expressly states that all IFRS principles and standards have been fully implemented. In preparing the consolidated financial statements, certain judgments and estimates made by the Group’s management have been used to quantify some of the assets, liabilities, revenue, expenses and commitments recognized. The most significant areas where judgment was required are: - - - The estimates refer to: - - - - - - - - - - - - - In relation to the COVID-19 pandemic, the degree of uncertainty generated in the macroeconomic and financial environment in which the Group operates, could affect the valuations and estimates made by Management to determine the carrying amounts of the more volatile assets and liabilities. As of December 31, 2022, according to the information available and considering a scenario in constant evolution, the main areas that required Management to use their judgment and make estimates were the following: i) measurement of expected credit losses on financial assets; ii) determination of impairment losses on non-financial assets; and iii) measurement of employee benefits, including actuarial assumptions. Although these judgments and estimates have been based on the best information available as of the date of issuance of these consolidated financial statements, future events may occur that would require a change (increase or decrease) to these judgments and estimates in subsequent periods. This change would be made prospectively, recognizing the effects of this change in judgment or estimation in the related future consolidated financial statements. 2.4 Subsidiaries are defined as those entities controlled either, directly or indirectly by Enel Chile. Control is exercised if and only if the following conditions are met: the Company has i) power over the subsidiary; ii) exposure, or rights to variable returns from these entities; and iii) the ability to use its power to influence the amount of these returns. Enel Chile has power over its subsidiaries when it holds the majority of substantive voting rights, or if this is not the case, when it holds the rights that grant it present capacity to direct their relevant activities, i.e., the activities that significantly affect the subsidiary’s performance. The Group will reassess whether or not it controls a subsidiary if facts and circumstances indicate that there are changes to one or more of the control elements listed above. Subsidiaries are consolidated as described in Note 2.7. The entities in which the Group has the ability to exercise control and consequently are included in consolidation in these consolidated financial statements are detailed below: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Taxpayer ID ​ ​ ​ ​ ​ ​ ​ Ownership % at 12-31-2022 ​ Ownership % at 12-31-2021 No. ​ Company ​ Country ​ Currency ​ Direct ​ Indirect ​ Total ​ Direct ​ Indirect ​ Total 77.282.311-8 ​ Enel Transmisión Chile S.A.

On January 1, 2021, the spin-off by Enel Distribución Chile S.A was formalized which resulted in the incorporation of a new company, Enel Transmisión Chile S.A., to which the assets and liabilities associated with the electric power transmission segment were assigned and also distributing to all the shareholders of Enel Distribución Chile S.A. a number of Enel Transmisión Chile S.A. shares equal to the shareholders’ interest in the spin-off company. This process was performed to comply with the requirements related to the exclusive line of business of distribution, in accordance with the latest amendments to Decree Law No. 4/2016 issued by the Ministry of Economy, Development and Reconstruction, which established the consolidated, coordinated and systematized text of Decree Law No. 1-1982 issued by the Ministry of Mining, General Law of Electric Services. ii. On January 1, 2021, the merger by the incorporation of Almeyda Solar SpA into Enel Green Power Chile S.A. took place. As a consequence, the latter became the legal successor company. iii. During the second quarter of 2021, the liquidation of the company “Empresa Nacional de Geotermia S.A.” (a subsidiary of Enel Green Power Chile S.A.) was finalized. The advance termination and liquidation of this company was approved by the shareholders at the Extraordinary Shareholders’ Meeting, held on November 24, 2020. iv. On November 1, 2021, Empresa de Transmisión Chena S.A. merged with Enel Transmisión Chile S.A. where the latter became the legal successor company. This transaction was approved by the Board of Directors of Enel Transmisión Chile S.A. at the extraordinary meeting held on October 20, 2021, in which the Directors in attendance unanimously ruled to buy from Enel Colina S.A., the minority interest held by the latter in the subsidiary Empresa de Transmisión Chena S.A., so as to hold 100% of that subsidiary’s shares. Consequently, an irregular merger was performed, by which Empresa de Transmisión Chena S.A. was absorbed by Enel Transmisión Chile S.A. without any liquidation thereof. 2022 v. On December 9, 2022, Enel Chile completed the sale of its subsidiary Enel Transmisión Chile S.A. to Sociedad Transmisora Metropolitana SpA (a company that is 100% controlled by Inversiones Grupo Saesa Ltda.). The sale was made through an Initial Public Offering between November 7 and December 6, 2022. Consequently, all the shares of Enel Transmisión Chile S.A. owned by Enel Chile, (equivalent to 99.09% ), were transferred to the new controlling shareholder (see Notes 5.2 and 33). 2.5. Investments in associates Associates are entities over which Enel Chile, either directly or indirectly, exercises significant influence. Significant influence is the power to participate in the decisions related to the financial and operating policy of the associate but without having control or joint control over those policies. In assessing significant influence, the Group takes into account the existence and effect of currently exercisable voting rights or convertible rights at the end of each reporting period, including currently exercisable voting rights held by the Company or other entities. In general, significant influence is presumed to be present in those cases in which the Group has more than 20% of the voting power of the investee. Associates are accounted for in the consolidated financial statements using the equity method of accounting as described in Note 3.i. ​ The detail of the companies that qualify as associates is the following: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Taxpayer ID ​ ​ ​ ​ ​ ​ ​ Ownership % at 12-31-2022 ​ Ownership % at 12-31-2021 No. ​ Company ​ Country ​ Currency ​ Direct ​ Indirect ​ Total ​ Direct ​ Indirect ​ Total 76.418.940-K ​ GNL Chile S.A. ​ Chile ​ U.S. dollar ​ — ​ 33.33% ​ 33.33% ​ — ​ 33.33% ​ 33.33% 76.364.085-K ​ Energía Marina SpA ​ Chile ​ Chilean peso ​ — ​ 25.00% ​ 25.00% ​ — ​ 25.00% ​ 25.00% 77.569.067-4 ​ Enel X Way Chile SpA (i) ​ Chile ​ Chilean peso ​ 49.00% ​ — ​ 49.00% ​ — ​ — ​ — 77.157.779-2 ​ Enel X AMPCI Ebus Chile SpA (ii) ​ Chile ​ U.S. dollar ​ — ​ — ​ — ​ — ​ 20.00% ​ 20.00% i. On April 4, 2022, the division of Enel X Chile S.A. was finalized to create a new company by the name of Enel X Way Chile SpA. Then, on May 31, 2022, 1,020 shares of that company were sold for ThCh$11,358,338, equivalent to a 51% interest ownership (see Note 6.d). ii. On December 6, 2022, our subsidiary Enel X Chile S.A. completed the sale of its 20% interest in Enel X AMPCI Ebus Chile SpA. to AMPCI EBUS Developments LLC (see Notes see 6.d and 33). 2.6. Joint arrangements Joint arrangements are defined as those entities in which the Group exercises control under an agreement with other shareholders and jointly with them, i.e., when decisions on the entities’ relevant activities require the unanimous consent of the parties sharing control. Depending on the rights and obligations of the participants, joint agreements are classified as: - Joint venture: an agreement whereby the parties exercising joint control have rights to the entity’s net assets. Joint ventures are included in the consolidated financial statements using the equity method of accounting, as described in Note 3.i. - Joint operation: an agreement whereby the parties exercising joint control have rights to the assets and obligations with respect to the liabilities relating to the arrangement. Joint operations are included in the consolidated financial statements recognizing the proportional interest in the assets and liabilities impacted by such operation. In determining the type of joint arrangement in which it is involved, the Group’s Management assesses its rights and obligations arising from the arrangement by considering the structure and legal form of the arrangement, the terms agreed by the parties in the contractual arrangement and, when relevant, other facts and circumstances. If facts and circumstances change, the Group reassesses whether the type of joint arrangement in which it is involved has changed. The detail of companies classified as joint ventures is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Ownership % at 12-31-2022 ​ Ownership % at 12-31-2021 Taxpayer ID No. Company Country Currency Direct Indirect Total Direct Indirect Total 77.110.358-8 ​ HIF H2 SpA.

On April 1, 2021, Enel Green Power Chile S.A. acquired an interest of 50% in the new company HIF H2 SpA., for the performance of green hydrogen projects in the Magallanes region. ii. On December 30, 2021, the sale of the entire interest that Enel Generación Chile S.A. held in Transmisora Eléctrica de Quillota Ltda., to APG Energy & Infra Investments Chile Expansion SpA and CELEO Redes Chile Expansion SpA was completed. iii. On October 28, 2021, our subsidiary Enel X Chile purchased a 10% interest in Sociedad de Inversiones K Cuatro SpA., and this interest is conditioned upon the long-term financial asset, because the Group did not have significant influence over it. On February 28, 2022, Enel X Chile increased its interest in Sociedad de Inversiones K Cuatro SpA. to 50% , thus satisfying the conditions to be classified as a joint venture, see Note 13.3.b. Subsequently, on December 6, 2022, our subsidiary Enel X Chile completed the sale of its entire stake in Sociedad de Inversiones K Cuatro SpA. to Enel X AMPCI Ebus Chile SpA, see Note 13.3. b. Currently, Enel Chile is not involved in any joint arrangement that qualifies as a joint operation. 2.7. Basis of consolidation and business combinations The subsidiaries are consolidated and all their assets, liabilities, revenues, expenses, and cash flows are included in the consolidated financial statements once the adjustments and eliminations of intra-group transactions have been made. The comprehensive income from subsidiaries is included in the consolidated statement of comprehensive income from the date when the Enel Chile obtains control of the subsidiary until the date on which it loses control of the subsidiary. The Group records business combinations using the acquisition method when all the activities and assets acquired meet the definition of a business and control is transferred to the Group. To be considered a business, a set of activities and assets acquired must include at least one input and a substantive process applied to it that, together, contribute significantly to the ability to create output. IFRS 3 provides the option of applying a “concentration test” that allows a simplified assessment of whether a set of acquired activities and assets is not a business. The concentration test is met if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. The operations of Enel Chile and its subsidiaries have been consolidated under the following basic principles: 1. At the date the Parent Company obtains control, the subsidiary’s assets acquired and its liabilities assumed are recorded at fair value, except for certain assets and liabilities that are recorded using valuation principles established in other IFRS standards. If the fair value of the consideration transferred plus the fair value of any non-controlling interests exceeds the fair value of the net assets acquired, this difference is recorded as goodwill. In the case of a bargain purchase, the resulting gain is recognized in profit or loss after reassessing whether all of the assets acquired and the liabilities assumed have been properly identified and following a review of the procedures used to measure the fair value of these amounts. For each business combination, IFRS allow valuation of the non-controlling interests in the acquiree on the date of acquisition: i) at fair value; or ii) for the proportional ownership of the identifiable net assets of the acquiree, with the latter being the methodology that the Group has systematically applied to its business combinations. If the fair value of all assets acquired and liabilities assumed at the acquisition date has not been completed, the Group reports the provisional values accounted for in the business combination. During the measurement period, which shall not exceed one year from the acquisition date, the provisional values recognized will be adjusted retrospectively as if the accounting for the business combination had been completed at the acquisition date, and also additional assets or liabilities will be recognized to reflect new information obtained about events and circumstances that existed on the acquisition date, but which were unknown to Management at that time.

ACCOUNTING POLICIES
Accounting Policies	3. ACCOUNTING POLICIES The main accounting policies used in preparing the accompanying consolidated financial statements are the following: a) Property, plant and equipment Property, plant and equipment are generally measured at acquisition cost, net of accumulated depreciation and any impairment losses experienced. In addition to the price paid to acquire each item, the cost also includes the following concepts where applicable: - Finance costs accrued during the construction period that are directly attributable to the acquisition, construction, or production of qualifying assets, which require a substantial period of time before being ready for use; such as e.g., electricity generation or distribution facilities. The Group defines “substantial period” as a period exceeding twelve months. On the other hand, the capitalization of interest is suspended for periods in which the performance of activities for a qualifying asset has been interrupted, if these periods are extended over time. The interest rate used is that corresponding to the specific financing or, if it does not exist, the average financing rate of the company making the investment (see Note 16.b.1). - Employee expenses directly related to construction in progress (see Note 16.b.2). - Future disbursements that the Group will have to make to close its facilities are added to the value of the asset at fair value, recognizing the related provision for dismantling or restoration. Changes in the measurement of the provision resulting from changes in the estimated amount or timing of future expenditures required to settle the obligation, or changes in the discount rate, are added to or deducted from the cost of the asset, as appropriate (see Note 25). Assets under construction are transferred to operating assets once the testing period has been completed and they are available for use, at which time depreciation begins. Expansion, modernization or improvement costs that represent an increase in productivity, capacity or efficiency, or a longer useful life are capitalized as an increase in the cost of the related assets. The replacement or overhaul of entire components that increase the asset’s useful life or economic capacity are recorded as an increase in cost of the related assets, derecognizing the replaced or overhauled components. Expenditures for periodic maintenance and repair are recognized directly as an expense for the year in which they are incurred. Property, plant and equipment, net of its residual value, is depreciated by distributing the cost of the different items that comprise it on a straight-line basis over its estimated useful life, which is the period during which the Group expects to use the assets. Useful life estimates and residual values are reviewed on an annual basis and if appropriate adjusted prospectively. In addition, the Group recognizes right-of-use assets for leases relating to property, plant and equipment in accordance with the criteria established in Note 3.f. The following are the main categories of property, plant and equipment with their related estimated useful lives: ​ ​ ​ ​ Class of property, plant and equipment Years of estimated useful life Buildings ​ 10 – 60 Plant and equipment ​ 6 – 65 IT equipment ​ 3 – 15 Fixtures and fittings ​ 2 – 35 Motor vehicles ​ 5 – 10 In addition, for further information, the following is a more detailed breakdown of the class of plant and equipment: ​ ​ ​ Class of plant and equipment Years of estimated useful life Generating plant and equipment ​ ​ Hydroelectric plants ​ ​ Civil engineering works ​ 10 – 65 Electromechanical equipment ​ 10 – 45 Combined cycle power plants ​ 10 – 25 Renewable ​ 10 – 50 Distribution plant and equipment ​ ​ High-voltage network ​ 10 – 60 Low- and medium-voltage network ​ 10 – 50 Measuring and remote control equipment ​ 10 – 50 Primary substations ​ 6 – 25 Natural gas transportation ​ ​ Gas pipelines ​ 20 ​ Land is not depreciated since it has an indefinite useful life, unless it relates to a right-of- use asset in which case it is depreciated over the term of the lease. An item of property, plant and equipment is written off when sold or otherwise disposed of, or when no future economic benefits are expected to be obtained from its use, sale or other disposal. Gains or losses arising from sales of property, plant and equipment or PP&E items retired, are recognized as “Other gains (losses)” in the statement of comprehensive income and are determined as the difference between the sale value and net carrying amount of the asset. b) Investment property “Investment property” basically includes land and buildings that are kept for the purpose of obtaining gains from future sales or lease arrangements. Investment property is measured at acquisition cost, net of accumulated depreciation and any impairment losses experienced. Investment property, excluding land, is depreciated by distributing the cost of the several elements that comprise it on a straight-line basis over the years of useful life. An investment property is derecognized on disposal, or when no future economic benefits are expected from use or disposal. Gains or losses arising from the sale or disposal of items of investment property are recognized as “Other gains (losses)” in the statement of comprehensive income and determined as the difference between the sales amount and the net carrying amount of the asset. The fair value of investment property is disclosed in Note 17. c) Goodwill Goodwill arising from business combinations and reflected in consolidation, represents the excess of the value of the consideration transferred plus the amount of any non-controlling interest over the net identifiable assets acquired and liabilities assumed, measured at fair value at the date of acquisition of the subsidiary. During the measurement period of the business combination, goodwill may be adjusted as a result of changes in the provisional amounts recognized for the assets acquired and liabilities assumed (see Note 2.7.1). Goodwill arising from acquisition of companies with functional currencies other than the functional currency of the Parent Company is measured in the functional currency of the acquiree and translated to Chilean peso using the exchange rate effective as of the date of the statement of financial position. After initial recognition, goodwill is not amortized, but rather, at the end of each accounting period, or when there are indications thereof, an impairment test is performed to determine whether any impairment has occurred that reduces its recoverable value to an amount lower than the recorded net cost, and if this is the case, the impairment is recorded in the statement of income for the period (see Note 3.e). d) Intangible assets other than goodwill Intangible assets are initially recognized at their acquisition cost or production cost, and are subsequently measured at their cost, net of their accumulated amortization and impairment losses experienced. Intangible assets are amortized on a straight-line basis over their useful lives starting from the time they are in use, except for those assets with indefinite useful lives, for which amortization is not applicable. As of December 31, 2022, and December 31, 2021, intangible assets with indefinite useful lives amounted to ThCh$6,550,168 and ThCh$14,766,953, respectively, mainly related to easements and water rights. The decrease in these assets at the end of December 2022 is mainly due to the transfer of ThCh$ 9,377,135 to assets classified as held for sale from Enel Transmisión Chile S.A. (see Note 5.2). An intangible asset is derecognized when it is sold or otherwise disposed of, or when no future economic benefits are expected from its use, sale or other disposal. Gains or losses arising from sales of intangible assets are recognized in profit or loss for the period and determined as the difference between the amount of the sale and the carrying amount of the asset. The criteria for recognizing impairment losses on these assets and, if applicable, recoveries of impairment losses recorded in prior periods are explained in letter e) of this Note below. d.1) Research and development expenses The Group recognizes the costs incurred in a project’s development phase as intangible assets in the statement of financial position as long as the project’s technical feasibility and future economic benefits have been demonstrated. Research costs are recorded as an expense in the consolidated statement of comprehensive income in the period in which they are incurred. d.2) Other intangible assets These assets correspond mainly to computer software, water rights and easements. They are initially recognized at acquisition or production cost and are subsequently valued at cost net of the related accumulated amortization and impairment losses, if any. Computer software is amortized (on average) over four years. Certain easements and water rights have indefinite useful lives and are therefore not amortized. e) Impairment of non-financial assets During the period, and mainly at the end of each reporting period, the Group evaluates whether there is any indication that an asset has been impaired. If any such indication exists, the Group estimates the recoverable amount of that asset to determine the amount of the impairment loss. For identifiable assets that do not generate cash flows independently, the Group estimates the recoverable amount of the Cash Generating Unit (CGU) to which the asset belongs, which is understood to be the smallest identifiable group of assets that generates independent cash inflows. Notwithstanding the preceding paragraph, for CGUs to which goodwill or intangible assets with indefinite useful lives have been allocated, a recoverability analysis is performed routinely at each year-end. The criteria used to identify the CGUs are based, in line with Management’s strategic and operating vision, within the specific characteristics of the business, the operating rules and regulations of the market in which the Group operates and corporate organization. Recoverable amount is the higher of fair value less costs of disposal and value in use, which is defined as the present value of the estimated future cash flows. In order to calculate the recoverable amount of Property, plant, and equipment, as well as of goodwill and intangible assets, at the level of each CGUs the Group uses value in use criteria in practically all cases. To estimate value in use, the Group prepares future pre-tax cash flow forecasts based on the most recent budgets available. These budgets include Management’s best estimates of a CGU’s revenue and costs using sector forecasts, past experience and future expectations. In general, these projections cover the next three years, estimating cash flows for subsequent years by applying reasonable growth rates which, in no case, are increasing rates nor exceed the average long-term growth rates for the particular sector. At the end of December 2022 and 2021, the rates used to extrapolate the projections were between 2.0% and 3.0%. These flows are discounted to calculate their present value at a pre-tax rate that includes the cost of capital of the business and the geographical zone where it is carried out. This calculation considers the current cost of money and the risk premiums used in general among analysts for the business and geographical zone. Future cash flows are discounted to calculate their present value at a pre-tax rate that covers the cost of capital for the business activity and the geographic area in which it is being carried out. The time value of money and risk premiums generally used among analysts for the business activity and the geographic zone are taken into account to calculate the pre-tax rate. The pre-tax discount rates, expressed in nominal terms, applied at the end of December 2022 were between 7.4% and 11.1% (at the end of December 2021 were between 6.0% and 7.7%). The Company’s approach to allocate value to each key assumption used to project cash flows, considers: - Demand evolution: the growth estimate has been calculated based on the projected increase in Gross Domestic Product (GDP), in addition to other assumptions used by the company regarding the evolution of consumption, such as the growth in the number of customers. - Energy purchase and sale prices: based on specifically developed internal projection models. The price of the planned “pool” is estimated by considering a number of determining factors, such as the different technology’ costs and productions and energy demand, among other items. - Regulatory measures: an important part of the Company’s business is regulated and subject to extensive standards, which could undergo revisions, either as a result of new laws or the amendment of existing laws, and therefore the projections include adequate application of the current standards, those that are currently being developed, and those expected to be effective during the projected period. - Installed capacity: in the estimating of the Group’s installed capacity, the existing facilities are taken into account, as well as the plans for both increasing capacity and capacity closure. The investment plan is constantly updated based on the evolution of the business, quality of service regulations determined by the regulator and changes in the business development strategy adopted by management. In the generation area, the investments necessary to maintain the installed capacity in adequate operating conditions are taken into account; in the distribution activity, investments for maintenance, improvement and strengthening of the network are considered, as well as the investments necessary to carry out the implementation of the technological improvement plan (Smart Meters). - Hydrology and NCRE: the projections are made from historical series of meteorological conditions and projecting an average year, based on these. - Fuel costs for the estimation of fuel costs take into consideration existing supply contracts and long-term projections of oil, gas or coal prices based on forward markets and available analysts’ estimates. - Fixed costs: these are projected considering the foreseen level of business activities, both in terms of the evolution of the workforce (considering salary raises in line with the CPI), and in term of other operating and maintenance costs, the level of projected inflation and long-term existing maintenance or other contracts. The efficiencies that the Group is adopting over time are also considered, such as those that arise from the initiatives for the digitalization of internal processes. - External sources are always considered to verify the assumptions related to the macroeconomic environment such as price evolution, GDP growth, demand, inflation, interest rates and exchange rates, among others. Past experience has demonstrated the reliability of the Company’s forecasts, which allows it to base key assumptions on historical information. During 2022, the deviations observed with respect to the projections used to perform impairment testing as of December 31, 2021, were not significant and cash flows generated in 2022 remained in a reasonable variance range compared to those expected for that period. If the recoverable amount of the CGU is less than the net carrying amount of the asset, the related impairment loss is recognized for the difference, and charged to “Impairment loss (impairment reversals) recognized in profit or loss” in the consolidated statement of comprehensive income. The impairment is first allocated to the CGU’s goodwill carrying amount, if any, and then to the other assets comprising it, prorated on the basis of the carrying amount of each one, limited to the fair value less costs of disposal, or value in use, where no negative amount could be obtained. Impairment losses recognized in prior periods for an asset other than goodwill are reversed, if and only if, there has been a change in the estimates used to determine the asset’s recoverable amount since the last impairment loss was recognized. If this is the case, the carrying amount of the asset is increased to its recoverable amount with a credit to profit or loss, but so that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset. For goodwill, impairment losses are not reversed in subsequent periods. f) Leases In order to determine whether an arrangement is, or contains, a lease, Enel Chile assesses the economic substance of the agreement, assessing whether the agreement conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Control is considered to exist if the customer has (i) the right to obtain substantially all the economic benefits arising from the use of an identified asset; and (ii) the right to direct the use of the asset. f.1) Lessee When the Group acts as a lessee at the commencement of the lease (i.e., on the date on which the underlying asset is available for use) it records a right-of-use asset and a lease liability in the statement of financial position. The Group initially recognizes right-of-use assets at cost. The cost of right-of-.use assets consist of: i) the amount of the initial measurement of the lease liability; (ii) lease payments made until the commencement date less lease incentives received, (iii) initial direct costs incurred; and (iv) the estimate of decommissioning or restoration costs. Subsequently, the right-of-use asset is measured at cost, adjusted by any remeasurement of the lease liability, less accumulated depreciation and accumulated impairment losses. A right-of-use asset is depreciated on the same terms as other similar depreciable assets, as long as there is reasonable certainty that the lessee will acquire ownership of the asset at the end of the lease. If no such certainty exists, the leased assets are depreciated over the shorter of the useful lives of the assets and their lease term. The same criteria detailed in Note 3.e are applied to determine whether the right-of-use asset has become impaired. Lease liabilities are initially measured at the present value of the lease payments, discounted at the Company’s incremental borrowing rate, if the interest rate implicit in the lease cannot be readily determined. The incremental borrowing rate is the interest rate that the company would have to pay to borrow over a similar term, and with similar security, the funds necessary to obtain an asset of similar value to the right-of-use asset in a similar economic environment. The Group determines its incremental borrowing rate using observable data (such as market interest rates) or by making specific estimates when observable rates are not available (e.g., for subsidiaries that do not engage in financing transactions) or when they must be adjusted to reflect the terms and conditions of the lease (e.g., when the leases are not in the subsidiary’s functional currency). Lease payments included in the measurement of liabilities comprise: (i) fixed payments, less any lease incentive receivable; (ii) variable lease payments that depend on an index or a rate; (iii) residual value guarantees if it is reasonably certain that the Group will exercise that option; (iv) the exercise price of a purchase option, if the Group is it is reasonably certain to exercise that option; and (v) penalties for terminating the lease, if any. After the commencement date, the lease liability increases to reflect the accrual of interest and is reduced by the lease payments made. In addition, the carrying amount of the liability is remeasured if there is a change in the terms of the lease (changes in the lease term, in the amount of expected payments related to a residual value guarantee, in the evaluation of a purchase option or in an index or rate used to determine lease payments). Interest expense is recognized as finance cost and distributed over the years making up the lease period, so that a constant interest rate is obtained in each year on the outstanding balance of the lease liability. Short-term leases of one year or less or leases of low value assets are exempt from the application of the recognition criteria described above, with the payments associated with the lease recorded as an expense on a straight-line basis over the term of the lease. Right-of-use assets and lease liabilities are presented separately from other assets and liabilities, respectively, in the consolidated statement of financial position. f.2) Lessor When the Group acts as a lessor, it classifies at the commencement of the agreement whether the lease is an operating or finance lease, based on the substance of the transaction. Leases in which all the risks and rewards incidental to ownership of an underlying asset are substantially transferred are classified as finance leases. All other leases are classified as operating leases. For finance leases, at the commencement date, the Company recognizes in its statement of financial position the assets held under finance leases and presents them as an account receivable, for an amount equal to the net investment in the lease, calculated as the sum of the present value of the lease payments and the present value of any accrued residual value, discounted at the interest rate implicit in the lease. Subsequently, finance income is recognized over the term of the lease, based on a model that reflects a constant rate of return on the net financial investment made in the lease. For operating leases, lease payments are recognized as income on a straight-line basis, over the term of the lease unless another type of systematic basis of distribution is deemed more representative. The initial direct costs incurred in obtaining an operating lease are added to the carrying amount of the underlying asset and are recognized as expense throughout the lease period, applying the same basis as for rental income. g) Financial instruments Financial instruments are contracts that give rise to both a financial asset in one entity and a financial liability or equity instrument in another entity. g.1) Financial assets other than derivatives The Group classifies its non-derivative financial assets, whether permanent or temporary, excluding investments accounted for using the equity method (see Notes 3.i and 13) and non-current assets and disposal groups held for sale or distribution to owners (see Note 3.k), into three categories: (i) Amortized cost This category includes the financial assets that meet the following conditions (i) the business model that supports the financial assets seeks to maintain such financial assets to obtain contractual cash flows, and (ii) the contractual terms of such financial assets give rise on specific dates to cash flows that are solely payments of principal and interest (SPPI criterion). Financial assets that meet the conditions established in IFRS 9, to be valued at amortized cost in the Group are: cash equivalents, accounts receivable and, loans. Such assets are recorded at amortized cost, which is the initial fair value, less repayments of principal, plus uncollected accrued interest, calculated using the effective interest method. The effective interest method is a method for calculating the amortized cost of a financial asset or a financial liability (or a group of financial assets or financial liabilities) and allocating the finance income or financial costs throughout the relevant period. The effective interest rate is the discount rate that exactly matches the estimated cash flows to be received or paid over the expected useful life of the financial instrument (or when appropriate in a shorter period of time), with the net carrying amount of the financial asset or financial liability. (ii) Financial Assets Recorded at Fair Value through Other Comprehensive Income This category includes the financial assets that meet the following conditions: (i) they are classified in a business model, the purpose of which is to maintain the financial assets both to collect the contractual cash flows and to sell them, and (ii) the contractual conditions meet the SPPI criterion. These financial assets are recognized in the consolidated statement of financial position at fair value when this can be determined reliably. For the holdings in unlisted companies or companies with low liquidity, it is usually not possible to determine the fair value reliably, therefore, when this occurs, such holdings are valued at their acquisition cost or for a lower amount if there is evidence of their impairment. Changes in fair value, net of their tax effect, are recorded in the consolidated statement of comprehensive income: Other comprehensive income, until the disposal of these financial assets, where the accumulated amount in this section is fully allocated to profit or loss for the period except for investments in equity instruments where the accumulated balance in other comprehensive income is never reclassified to profit or loss. In the event that the fair value is lower than the acquisition cost, if there is objective evidence that the asset has suffered an impairment that cannot be considered as temporary, the difference is recorded directly in the loss for the period. (iii) Financial Assets Recorded at Fair Value through Profit or Loss This category includes the trading portfolio of the financial assets that have been allocated as such upon their initial recognition and which are managed and assessed according to the fair value criterion, and the financial assets that do not meet the conditions to be classified in the two categories indicated above. These are valued in the consolidated statement of financial position at fair value, and variations in their value are recorded directly in income when they occur. g.2) Cash and cash equivalents This item within the consolidated statement of financial position includes cash and bank balances, time deposits, and other highly liquid investments (with original maturity of less than or equal to 90 days) that are readily convertible into cash and are subject to insignificant risk of changes in value. g.3) Impairment of financial assets Following the requirements of IFRS 9, the Group applies an impairment model based on the determination of expected credit losses, based on the Group’s past history, existing market conditions, as well as forward-looking estimates at the end of each reporting period. This model is applied to financial assets measured at amortized cost or measured at fair value through other comprehensive income, except for investments in equity instruments. Expected credit loss is the difference between the contractual cash flows that are due in accordance with the contract and all the cash flows that are expected to be received (i.e. all cash shortfalls), discounted at the original effective interest rate. It is determined considering: i) the Probability of Default (PD); ii) Loss Given Default (LGD), and iii) Exposure at Default (EAD). To determine the expected credit losses the Group applies two separate approaches: • General approach: applied to financial assets other than trade accounts receivable, contractual assets or lease receivables. This approach is based on the evaluation of significant increases in the credit risk of financial assets, from the date of initial recognition. If on the reporting date of the financial statements the credit risk has not increased significantly, the impairment losses are measured related to the expected credit losses in the next 12 months; if, on the contrary, the credit risk has increased significantly, the impairment is measured considering the expected credit losses throughout the lifetime of the asset. In general, the measurement of expected credit losses for financial assets other than trade accounts receivable, contractual assets or lease receivables, are performed separately. • Simplified approach: The Group applies a simplified approach for trade receivables, contract assets and lease receivables so that the impairment provision is always recognized related to the lifetime expected credit losses for the asset. This is the approach that the Group has mostly applied because trade receivables represent the main financial asset of Enel Chile and its subsidiaries. For trade accounts receivable, contractual assets and lease receivables, the Group applies two types of evaluations of expected credit losses: - Collective evaluation: based on grouping accounts receivable into specific groups or “clusters”, taking into account each business and the local regulatory context. Accounts receivables are grouped according to the characteristics of customer portfolios in terms of credit risk, maturity information and recovery rates. A specific definition of default is considered for each group. To measure the expected credit losses collectively, the Group considers the following assumptions: - PD: average default estimate, calculated for each group of trade receivables, taking into account a minimum of 24-month historical data. - LGD: calculated based on the recovery rates of a predetermined section, discounted at the effective interest rate; and - EAD: accounting exposure at the reporting date, including invoices issued but not due and invoices pending issuance for services rendered, net of potential cash deposits obtained as guarantees. - Analytical or individual evaluation: if accounts receivables are considered individually significant by Management and there is specific information regarding any significant increase in the credit risk, the Group applies an individual evaluation of accounts receivable. For the individual evaluation, the PD is obtained mainly from an external supplier, when it is possible to do so, and the LGD through an internal model that considers the recovery rate and other contractual and financial characteristics of accounts receivable. The expected credit loss is obtained by multiplying both factors by the EAD, which is defined as the accounting exposure at the reporting date, including the invoices issued but not due and invoices pending issuance for services rendered, net of potential cash deposits obtained as guarantees. On the basis of the benchmark market and the regulatory context of the sector as well as the recovery expectations after 90 days for those accounts receivable, the Group mainly applies a predetermined definition of 180 days overdue to determine expected credit losses, since this is considered an effective indicator of a significant increase in credit risk and, accordingly, in the impairment of receivables. Based on specific evaluations performed by Management, the prospective adjustment can be applied considering qualitative and quantitative information to reflect possible future events and macroeconomic scenarios, which may affect the risk of the portfolio or the financial instrument. g.4) Financial liabilities other than derivatives General financial liabilities are initially recognized, at fair value net of any costs incurred in the transaction. In subsequent periods, these obligations are measured at their amortized cost using the effective interest method (see Note 3.g.1). Lease liabilities are initially measured at the present value of future lease payments, determined in accordance with the criteria described in Note 3.f. In the particular case that a liability is the hedged item in a fair value hedge, as an exception, such liability is measured at its fair value for the portion of the hedged risk. In order to calculate the fair value of debt, both when it is recorded in the statement of financial position and for fair value disclosure purposes as shown in Note 23, debt has been divided into fixed interest rate debt (hereinafter “fixed-rate debt”) and floating interest rate debt (hereinafter “floating-rate debt”). Fixed-rate debt is that on which fixed-interest coupons established at the beginning of the transaction are paid explicitly or implicitly over its term. Floating-rate debt is that debt issued at floating interest rate, i.e., each coupon is established at the beginning of each period based on the benchmark interest rate. All debt has been measured by discounting expected future cash flows with a market interest rate curve based on the payment currency. ​ g.5) Derivative financial instruments and hedge accounting Derivatives held by the Group are transactions entered into to hedge interest and/or exchange rate risk, intended to eliminate or significantly reduce these risks in the underlying transactions being hed

SECTOR REGULATION AND ELECTRICITY SYSTEM OPERATIONS
Sector Regulation And Electricity System Operations	4. SECTOR REGULATION AND ELECTRICITY SYSTEM OPERATIONS a) Regulatory Framework The Chilean electricity sector is regulated by the General Law of Electricity Services (Ley General de Servicios Eléctricos), contained in Decree Law (DFL) No. 1 of 1982, of the Ministry of Mining, whose restated and coordinated text was established by DFL No. 4 of 2006 of the Ministry of Economy (“Electricity Law”) its subsequent amendments and its corresponding Regulations, contained in Supreme Decree D.S. No. 327 of 1998. The main authority on Chilean energy matters is the Ministry of Energy, which is responsible for proposing and conducting public policies on energy, strengthening coordination, and facilitating a comprehensive vision of the sector. Within the Ministry of Energy, the Chilean National Energy Commission (or “CNE” in its Spanish acronym), is the regulatory body for the Chilean electricity sector and the Superintendency of Electricity and Fuel (“SEF”), is the oversight entity. The Ministry of Energy also includes the Chilean Commission of Nuclear Energy (CChEN) and the Energy Sustainability Agency. The CNE is the entity in charge of approving the annual transmission expansion plans, responsible for the indicative plan for the construction of new electricity generation facilities, and proposing regulated tariffs to the Ministry of Energy for approval. Meanwhile, the SEF inspects and oversees compliance with the law, rules, regulations, and technical norms applicable to the generation, transmission, and distribution of electricity, as well as liquid fuels and gas. Additionally, the legislation considers an Expert Panel, composed of expert professionals whose key job is to decide on any discrepancies produced in terms of the matters established in the Electricity Law and in the application of other laws on energy, through binding rulings. The Electricity Law establishes a National Electric Coordinator, an independent body governed by public law, in charge of the operation and coordination of the Chilean electricity system whose main objectives are to: i) Preserve the security of the service, ii) Guarantee an economic operation of the interconnected installations of the system and iii) Guarantee open access to all transmission systems. Its main activities include coordinating the Electricity Market, authorizing connections, managing complementary services, implementing public information systems, monitoring competition and the payment chain, among others. From a physical perspective, the Chilean electricity sector is divided into three main networks: the National Electricity System (“SEN” in its Spanish acronym), which extends from Arica in northern Chile to Chiloé in southern Chile, and two smaller isolated networks: Aysén and Magallanes. The Chilean electricity industry can be divided into three business segments: generation, transmission and distribution. The electricity facilities associated with these three segments have the obligation to operate in an interconnected and coordinated manner, with the primary objective of providing electricity to the market at minimal cost and within the service quality and safety standards required by the electricity regulations. Due to their essential nature, the transmission and distribution activities constitute natural monopolies, therefore their segments are regulated as such by the electricity regulations, requiring free access to the grids and definition of regulated rates. In the electricity market, two products (Energy and Capacity) are traded, and different services are provided. In particular, the National Electric Coordinator is responsible for making balances, determining the corresponding transfers between generators, and calculating the marginal time-specific cost, the price at which energy transfers are valued. The CNE determines the prices of Capacity. Consumers are classified according to their demand as regulated or unregulated customers. Regulated customers are those with a connected capacity of up to 5,000 kW. Customers with a connected capacity between 500 kW and 5,000 kW may choose between the free or regulated rate system. Limits to Integration and Concentration In Chile, there is legislation to defend free competition, which along with the specific regulations applicable to electricity, define the criteria to avoid certain levels of economic concentration and/or abusive market practices. In principle, companies are allowed to participate in different activities (generation, transmission, distribution, commercialization) as long as there is adequate separation of these, both in accounting and corporate terms. Nevertheless, the transmission sector is where most restrictions are imposed, mainly due to its nature and the need to guarantee proper access to all agents. The Electricity Law establishes limits to the participation of generation or distribution companies in the Domestic Transmission segment and prohibits Domestic Transmission companies to participate in the generation and distribution segment. Moreover, as of January 1, 2021, Exempt Resolution No. 173 of the CNE determined the scope of the exclusive line of business and separate regulatory accounting obligations, for the provision of public electric distribution services in accordance with Law No. 21,194. a.1 Generation Segment Electricity generation companies must operate under the operation plan designed by the National Electric Coordinator. However, each company can freely decide whether to sell its energy and capacity to regulated or unregulated customers. Any surplus or deficit between sales to customers and production is sold to other generators at the spot market price. A generation company may have the following types of customers: • Unregulated Customers: users with a connected capacity of more than 5,000 kW (mainly industrial and mining companies), or customers with connected capacity between 500 and 5,000 kW that choose to be an unregulated customer but must remain in the selected category for at least four years . These consumers can freely negotiate their electricity supply prices with suppliers. • Distribution Companies: those that deliver supply to their regulated customers. Distribution companies buy energy from generation companies through a public bid process regulated by the CNE. • Other Generation Companies: The relationship between generation companies may come about through bilateral contracts or transfers in the short-term or Spot Market. The latter correspond to energy and capacity transactions among generation companies coordinated by the National Electric Coordinator to achieve the cost-effective operation of the system; any surplus (deficit) in production with respect to their commercial commitments are transferred through sales (purchases) to other generators within the system, and energy is valued at marginal cost and capacity at the corresponding regulated price established twice a year by the authority. In Chile, the capacity to be paid to each generator depends on a calculation performed centrally by the National Electric Coordinator each year, based on current regulations, in order to obtain the sufficiency capacity for each plant. This value depends primarily on the availability of the facilities themselves and the technology-specific generation resource. Law No. 20,257, dated April 2008, encourages the use of Non-Conventional, Renewable Energies (NCRE). The current version of this law states that by 2025, 20% of the electricity matrix will be covered by NCREs, adhering to the withdrawal schedule established in the previous law for contracts in force as of July 2013. a.2 Transmission Segment Transmission segment is divided into five segments: Domestic Transmission, Transmission for Development Poles, Zonal Transmission, Dedicated Transmission and International Interconnection Systems. The transmission facilities are subject to an open access regime, and may be used by any interested user under non-discriminatory conditions. The remuneration of the existing facilities of the National, Zonal, Development Poles Transmission segments and the dedicated transmission facilities used by users subject to price regulation is determined through a tariff-setting process conducted every four years. This process determines the Annual Value of Transmission, composed of efficient operating and maintenance costs and the annual value of investment, determined according to a discount rate (7% minimum and 10% maximum, after taxes) set by the authority and the economic useful lives of the facilities. The planning of the National, Zonal and Development Pole Transmission systems relates to a regulated and centralized process, for which both the National Electrical Coordinator and the interested parties annually propose expansion works. The CNE is in charge of annually preparing an expansion plan through Technical Reports, which can be observed and disagreed with before the Expert Panel. a.3 Distribution Segment The distribution system corresponds to electric facilities aimed at supplying electricity to final customers, at a maximum voltage of 23 kV. Distribution companies operate under a public service concessions system and are required to provide service to all customers and supply electricity to all customers subject to regulated rates (customers with connected capacity less than 5,000 kW, with the exception of customers between 500 and 5,000 kW who may opt for the free rate). Note that free-rate customers may negotiate their supply with any supplier, and must pay a regulated toll for using the distribution network. Regarding the supply for users subject to price regulation, the law establishes that distribution companies must provide an ongoing energy supply, based on open, non-discriminatory and transparent public bids. These bid processes are designed by the CNE and performed at least 5 years ahead of time, with a supply contract agreement of up to 20 years. In the case of unforeseen variations in demand, the authority has the power to carry out a short-term bid. There is also a regulated procedure to remunerate potential supply not under contract. The fee-setting in this segment is performed every four years based on a cost study to determine the Added Value of Distribution (AVD). The AVD is determined according to an efficient model company scheme and the concept of typical area. To determine the AVD, the CNE classifies companies with similar distribution costs into groups known as “typical areas.” For each typical area, the CNE engages independent consultants to carry out a study to determine the costs associated with an “efficient model company”, considering fixed costs, average energy and capacity losses, standard investment, maintenance, and operating costs related to distribution, including some restrictions faced by real distribution companies. The annual costs of investment are calculated considering the New Replacement Value (NRV) of the facilities adapted to demand, their useful life, and a rate of renewal, calculated every four years by the CNE, will be a yearly after-tax rate of between 6% and 8%. Subsequently, the after-tax rate of return for each distribution company must be between three percentage points below and two percentage points above the rate calculated by the CNE. Additionally, and along with the calculation of the AVD, every four years the CNE reviews the related services not consisting of energy supply which the Free Competition Defense Court qualifies as subject to rate regulation. ​ b) Regulatory matters 2019 – 2022 Laws (i) Law No. 21,185 – Creates a Transitional Mechanism for Stabilizing Customers´ Electricity Prices under the Regulated Price System On November 2, 2019, the Ministry of Energy published Law No. 21,185, which established a transitional mechanism for stabilizing customers’ electricity prices under the regulated price system. Through this Law, between July 1, 2019 and December 31, 2020, the prices to be transferred to regulated customers are the price levels defined for the first half of 2019 (Decree 20T/2018) to be referred to as “Stabilized Price to Regulated Customers” (“PEC” in its Spanish acronym). Between January 1, 2021 and until the end of the stabilization mechanism, prices shall be those defined in the semiannual price-setting processes referred to in article 158 of the Electricity Law, but may not be higher than the adjusted PEC according to the Consumer Price Index beginning on January 1, 2021, based on the same date (adjusted PEC). The billing differences due to the application of this mechanism lead to an account receivable in favor of the generators with a limit of US$1,350 million. The balance must be recovered by December 31, 2027. The technical provisions of this mechanism are established in the National Energy Commission’s Exempt Resolution No. 72/2020 and its amendments. It should be noted that the fund limit was reached in January 2022. (ii) Law No. 21,472 – Creates a price stabilization fund and establishes a new temporary electricity price stabilization mechanism for customers subject to price regulation On August 2, 2022, the Ministry of Energy published Law No. 21,472. This law establishes a Temporary Customer Protection Mechanism (MPC) that will stabilize energy prices in the National Electric System and medium-sized systems in addition to those established by Law No. 21,185, for regulated customers under the General Law of Electric Services. The purpose of the MPC is to pay for the differences that may arise between the billing of the distribution companies to end customers and the amount payable to generation companies. The resources available for the MPC may not exceed US$1,800 million. This mechanism will be extended until the amount contemplated by the law is used in full. From 2023 onwards, the National Energy Commission must project the payment of the Remaining Balance every six months up to December 31, 2032 (but not later). On March 14, 2023, Exempt Resolution No. 86 was published, establishing provisions, procedures, deadlines, and conditions for the proper application of Law. (iii) Law No. 21,194 - Reduces the Profitability of Distribution Companies and Modifies the Electricity Distribution rate process On December 21, 2019, the Chilean Ministry of Energy issued Law No. 21,194, (the “Distribution Short Law”) that reduces distribution companies’ rate of return and improves the electricity tariff setting process. The Distribution Short Law eliminates prior methodology that involved weighing the results of the VAD study performed by the CNE (two-thirds) and VAD study performed by distribution companies, (one-third), and replaces it by using only the CNE’s VAD study. The discount rate in the calculation of the annual investment cost was also modified. The previous 10% real annual pre-tax discount rate was replaced by a 6-8% real annual after-tax discount rate to be calculated every four years. The after-tax economic rate of return of distribution companies may not be more than 2 percentage points higher or 3 percentage points lower than the rate determined by the CNE. Additionally, distribution companies must have an exclusive line of business as of January 2021. (iv) Law No. 21,505 on Promotion of Energy Storage and Electromobility On November 21, 2022, Law No. 21,505 was published, which encourages the storage of electric power through remuneration for energy, power sufficiency and complementary services to energy storage systems; as well as electromobility, through a temporary price reduction of the registration certificate for electric vehicles. This law allows for new electromobility business models and the option to charge electric vehicles batteries through the provision of services to the grid. In addition, it includes projects related to generation and consumption infrastructure for renewable energy projects, plus storage in order to remove energy from and inject surpluses into the electric system. (v) CNE Exempt Resolution No. 176 /2020 – Exclusive Line of Business On June 9, 2020, Exempt Resolution No. 176 was published in the Official Gazette. This resolution determines the scope of the Exclusive Line of Business and Separate Accounting obligations, for the provision of public electricity distribution service in accordance with Law No.21,194. According to this Resolution and its amendments, the distribution companies acting as public service concessions companies and operating in the National Electricity System must be constituted exclusively as distribution companies and may only perform economic activities aimed at providing public distribution services, in accordance with the requirements established by law and current regulations. The requirements contained in such resolution have been applicable since January 1, 2021. Notwithstanding the above, those operations that by nature could not be performed prior to such date had to be reported and explained to the CNE, along with a planning schedule and compliance periods for the respective requirements, which under no circumstances could extend beyond January 1, 2022. (vi) Law No. 21,305 – Energy Efficiency On February 13, 2021, the Energy Efficiency Law was passed for the purpose of preparing the First National Energy Efficiency Plan, which shall be renewed every five years, with the goal of reducing the energy efficiency by at least 10% between 2019 and 2030. Additionally, this plan must consider a goal for consumers with energy management capacity to reduce their energy intensity by an average of at least 4% during the effective term. The Energy Efficiency Law includes other matters such as the construction of housing, buildings of public use, corporate buildings, and office buildings that must have an energy classification in order for final reception by the respective Department of Municipal Works. It also establishes that the Ministry of Energy will regulate the interoperability of the electric vehicle charging system. On February 25, 2022, Supreme Decree No. 12 ratified the regulations establishing the interoperability of electric vehicle charging systems, which was sent to the Comptroller General's Office of the Republic on May 13, 2022. This decree has not yet been reviewed by the Comptroller General's Office of the Republic. It will go into effect once it has been published in the Official Gazette. This plan was created based on Article 1 of the Energy Efficiency Law, which indicates that, every five years, the Ministry of Energy must prepare a National Energy Efficiency Plan that includes the following matters, at a minimum: residential energy efficiency; minimum standards and device labels; energy efficiency in construction and transport; energy efficiency and smart cities; energy efficiency in production sectors; and education and training on energy efficiency. Moreover, short-, medium-, and long-term goals must be established, as well as the necessary plans, programs, and actions to achieve these goals. On March 4, 2022, the National Energy Efficiency Plan was ratified, but was later withdrawn by the Ministry of Energy. On September 13, 2022, the Ministry of Energy published Decree No. 28 corresponding to the Regulations on Energy Management of consumers with energy management capacity and of public entities, as referred to by articles 2 and 5 of Law No. 21,305. (vii) Law No. 21,249 – Exceptional provision of the measures indicated for end users of water and sanitation, electricity, and gas services. On August 8, 2020, Law No. 21,249 the Law on Utility Services (Ley de Servicios Básicos), was passed, this law considers extraordinary measures to support the most vulnerable customers. These measures include the suspension of the electricity supply disconnection due to default and the possibility of signing agreements to pay off electricity debt in installments, in both cases, for a group of vulnerable customers. On December 29, 2020, Law No. 21,301 was ratified and extended the terms defined in Law No. 21,249, establishing a benefit duration of 270 days following ratification of this new Law, as opposed to the initial 90 days. Likewise, the number of installments was modified to a maximum of 36, instead of the previously defined maximum of 12 installments. On May 13, 2021, Law No. 21,340 was passed to extend the effects of Law No. 21,249 to December 31, 2021. Additionally, the number of installments was modified to a maximum of 48, instead of the previously defined maximum of 36 installments. (viii) Law No. 21,423 – Regulates the proration and payment of water and electricity service debts incurred during the Covid-19 pandemic and establishes subsidies for vulnerable customers On February 11, 2022, the law was published to regulate the proration and payment of water and electricity service debts incurred during the Covid-19 pandemic and establish subsidies for vulnerable customers, in order to address electricity debts generated between March 18, 2020, and December 31, 2021, on past-due bills. The law establishes that the debts of customers with an average consumption of less than 250 kWh per month during 2021 will be automatically divided into 48 monthly installments. These installments may not exceed 15% of the average monthly bill. These customers will receive a subsidy from the Chilean government equivalent to this same value (15% of the average monthly bill). Therefore, in practice, users will only have to pay their monthly electricity consumption and stay up-to-date with payments. In the case of customers with an average monthly consumption of over 250 kWh per month during 2021, the term was extended until June 30, 2022, for them to approach their electricity distribution companies to prorate the total debt in up to 48 installments, with no fines or interest. On June 23, 2022, the Ministry of Energy published the procedure for the payment of subsidies established in Law No. 21,423, which regulates the proration and payment of water and electricity services generated during COVID-19 and establishes subsidies for vulnerable customers. On September 30, 2022, the Superintendency of Electricity and Fuel issued Circular No. 140129 to modify the instructions provided by SEC Circular No. 119977, regarding the termination of the customer subsidy benefit. Among these amendments is the reincorporation of the customer subsidy benefit once the customer has paid off its debt with the respective concessionaire company. (ix) Law No. 21,455 – Framework for Climate Change On May 30, 2022, the Ministry of Energy published Law No. 21,455 Framework for Climate Change, which establishes the country's carbon neutrality by 2050 at the latest, and creates the Long-Term Climate Strategy, an instrument recognized in the Paris Agreement, and which will define the national greenhouse gas emissions budget by 2030 and 2050, and sectoral greenhouse gas emissions budget by 2030. (x) Electricity Portability Bill On September 9, 2020, a bill was submitted to the Chilean Chamber of Deputies that would modify the Electricity Law in order to establish the right to electricity portability and to introduce the figure of energy trader. This would uncouple all services that may be offered to the distribution company’s final customers, so that the distribution company would be dedicated exclusively to the operation of its grids. It considers a transition period to be defined in future decrees, so that regulated consumers in certain areas may gradually obtain the freedom to choose their energy trader. The main point of discussion of this bill is related to the gradual market liberalization and could affect existing regulated contracts. ​ (xi) Non-Conventional Renewable Energies Bill On November 23, 2021, a bill was submitted to the Chilean Chamber of Deputies to establish the participation of renewable energies in the Chilean energy matrix through fostering small-scale distributed generation, especially in net billing projects, the creation of a renewable energy traceability system and an increased share of NCREs in the National Electric System. This bill establishes an annual production goal of 60% renewable energy by 2030, for contracts signed after January 1, 2023; and 40% per hour block for contracts signed after July 1, 2023. The bill is currently under legislative discussion. (xii) Green Hydrogen Bill On November 23, 2021, a bill was submitted to the Chilean Chamber of Deputies to establish the production and use of green hydrogen in the country, establishing hydrogen blends in natural gas networks and allowing Empresa Nacional del Petróleo (ENAP) to participate in its development. It proposes that gas line distribution concessions companies be required to use green hydrogen in their gas lines, which would generate local demand for green hydrogen, while also using the existing gas infrastructure and industry experience. Moreover, the project will allow for the use of other gases, such as biomethane or synthetic methane, to meet this share within natural gas blends. Regulations Published in 2019 - 2022 Regulations on Complementary Services Regulations on the Coordination and Operation of the SEN Regulation Standard 4 Regulations on Net billing Modification to the Regulations on Sufficiency Capacity New Regulations on Sufficiency Capacity: Draft Regulation on Distribution Tolls: Preventive Decree on Rationing: ● On August 18, 2021, the Ministry of Energy issued Supreme Decree No. 51/202 to implement preventive measures of electricity rationing until June 30, 2022, introducing actions for the generation, transmission, and distribution segments. It allows the coordinator to establish water reserves and orders conservative criteria when using water for the programming of operations. ● On January 12, 2022, the Ministry of Energy issued Supreme Decree No. 1/2022, which extends the preventive decree on rationing until September 30, 2022, and designates the National Electric Coordinator to determine a security diesel for the purpose of remunerating the additional availability of plants powered by this fuel. The fixed costs of the provision will be remunerated proportionally to the withdrawal made by the generation companies. ● On March 22, 2022, the Ministry of Energy issued Supreme Decree No. 29/2022 to define a Water Reserve of 650 GWh. ● On March 22, 2022, the Ministry of Energy issued Supreme Decree No. 66/2022 to reduce the Water Reserve to 205 GWh. ● On August 31, 2022, the Ministry of Energy issued Supreme Decree No. 74/2022 to extend the preventative decree on rationing to March 31, 2023 and reduce the Water Reserve to 66 GWh. Modification of the GNL Technical Standards Regulation for small-scale means of generation Modification of the Regulations of the General Law of Electric Services Emissions Standard c) Tariff Revisions and Supply Processes In the electricity market there is a continuous revision of tariffs and supply processes that affect those volumes that were realized in previous periods on the dates of publication of these revisions. Therefore, the following discloses those rules that are currently applicable to the Group. ​ c.1 Distribution Price-Setting 2016-2020 The price-setting process for the 2016-2020 period culminated on August 24, 2017 with the publication of Decree No. 11T/2016 in the Official Gazette, which establishes the distribution rate formulas effective from November 4, 2016. On September 28, 2018, the Ministry of Energy Decree No. 5T went into effect, updating Decree No. 11T/2016 by the same Ministry and modifying the electricity rates in force for the distribution segment until the next price-setting process. On July 26, 2019, through Ordinary Official Letter No. 15699/2019, the SEF instructed a plan of action to apply the adjustment indicated in the CNE Ordinary Official Letter No. 490/2019, with respect to the Ministry of Energy Decree No. 5T/2018. The adjustment was effective retrospectively beginning on September 28, 2018.

This variation is mainly due to the following factors: (i) an increase of ThCh$266,843,088 due to the effects of Law No. 21,472, (whose implementation is still pending); (ii) an increase of ThCh$129,508,002 associated with pending billing re-settlements to Electricity Distribution companies; and (iii) an increase of ThCh$200,889,730 due to higher sales and average prices expressed in Chilean Pesos in the Generation and Distribution and Networks segments. General background: During the month of January 2022, the limit of US$1,350 million was reached for accounts receivable from regulated customers, as established by Law No. 21,185, which created a Temporary Price Stabilization Mechanism for that segment of customers (see Note 9.a.1.ii). This implied that the mechanism was no longer applied and, as a result, short-term accounts receivable from regulated customers have accumulated since February 2022, for the difference between the theoretical prices based on the conditions established in the contracts with the respective Electricity Distribution companies and the regulated rates currently applied to the end user’s bill. On August 2, 2022, Law No. 21,472 was published, which created a price stabilization fund and established a new temporary price stabilization mechanism for regulated customers. Law No. 21,472 establishes a customer protection mechanism aimed at paying differences resulting between the prices of the respective regulated supply contracts and the stabilized price. These differences will be covered by a temporary fund of US$1,800 million through a new instrument known as a Payment Document, issued monthly by the General Treasury of the Republic to electricity generation companies, denominated in United States dollars, adjustable, transferable, with a maximum maturity date of December 2032 and state guarantee. It should be noted that all fund balances generated that are over US$1,350 million as indicated in Law No. 21,185, are recognized as part of the mechanism established in Law No. 21,472. The fund will be financed through an additional fee charged to end users segmented by consumption level, where customers with a monthly consumption of less than 350 kWh will be exempt from such fee, as well as micro and small companies with monthly consumption up to 1,000 kWh. The fund will be managed by the General Treasury of the Republic, with fiscal contribution of US$20 million per year, effective until December 31, 2032. The Exempt Resolution No. 86 that establish the technical provisions for implementation of Law No. 21,472 was published on March 14, 2023, that enable the settlement of accounts receivable associated with the implementation of this Law. a.1.ii) On the one hand, long-term accounts receivable increased by ThCh$86,642,098 with respect to the close of 2021, and this increase is explained primarily by the following: (i) an increase of ThCh$133,652,713 in accounts receivable that the Group should transfer to end customers and then repay to the tariff stabilization fund (by application of Law 21,472); and (ii) a decrease of ThCh$60,431,732 related to new sales of accounts receivable associated with Law 21,185 (see section a.2.II in this same note), which are described as follows: The law was published on November 2, 2019, by the Ministry of Energy, and creates a Transitory Mechanism to Stabilize Electricity Prices for Customers Subject to Rate Regulation. Pursuant to this law, between July 1, 2019 and December 31, 2020, the prices to be transferred to regulated customers are the price levels defined for the first half of 2019 (Decree 20T/2018) and will be referred to as “Stabilized Price to Regulated Customers” (“PEC” in its Spanish acronym). Between January 1, 2021 and up to the end of the stabilization mechanism, prices shall be those defined in the semiannual price-setting processes mentioned in article 158 of the Electricity Law, but could not be higher than the adjusted PEC according to the Consumer Price Index beginning on January 1, 2021, based on the same date (adjusted PEC). The differences to be produced between the billing period while applying the stabilization mechanism and the theoretical billing, considering the price that would have been applied according to the conditions of the respective contracts with the electricity distribution companies, will generate an account receivable in favor of the electricity generation companies, up to a maximum of US$1,350 million until 2023. The limit was reached in January 2022. All billing differences will be recorded in USD and will not accrue financial remuneration until December 31, 2025. The balance must be recovered by December 31, 2027. The application of this law generates a greater delay in the billing and collection of sales generated by the Company´s electricity generation segment, with the corresponding financial and accounting impact this situation generates. In the case of the Company´s electricity distribution segment, the financial and accounting effects are neutralized (pass-through principle). On September 14, 2020, the National Energy Commission published Exempt Resolution No. 340, which modified the technical provisions for the implementation of Law No. 21,185. This resolution clarified that the payment to each supplier “must be allocated to the payment of Balances chronologically, paying from the oldest to the newest Balances,” and not on a weighted basis over the total balances pending payment, as the industry practice had been until that date. In addition, this resolution established that the payment of balances shall be performed using the US$ exchange rate observed on the sixth business day following publication of the Coordinator’s Balance Payment Chart, instead of the average US$ exchange rate during the billing month, as established up to that moment. As a result of the abovementioned situations in paragraphs a.1.i) and a.1.ii) and after eliminating transactions between related companies, the accounting effects recorded by the Group are summarized as follows: - Classification as current in trade receivables in the amount of ThCh $266,843,088 as of December 31, 2022 (ThCh $0 as of December 31, 2021). - Classification as non-current in trade receivables in the amount of ThCh $500,707,110 as of December 31, 2022 (ThCh $415,664,120 as of December 31, 2021) and trade payables for the purchase of energy from suppliers in the amount of ThCh $308,013,985 (ThCh $174,373,938 as of December 31, 2021). See note 24. - Lower energy sales revenue of ThCh $6,706,741 as of December 31, 2022 (ThCh $12,245,142 as of December 31, 2021). - Lower energy purchase of ThCh $2,088,485 as of December 31, 2022 (ThCh $3,388,944 as of December 31, 2021). - Higher finance income of ThCh $7,455,121 as of December 31, 2022 (ThCh $4,802,376 and ThCh $15,328,268 as of December 31, 2021 and 2020). See note 34. - Higher finance costs of ThCh $2,235,708 as of December 31, 2022 (higher financial costs ThCh$ 2,409,504 and ThCh $4,518,268 as of December 31, 2021, and 2020). See note 34. - Net gain from foreign currency translation of ThCh$ 4,801,364 as of December 31, 2022 (corresponding to a gain of ThCh$ 28,572,166 and a loss of ThCh $25,260,383 of December 31, 2021, and 2020), for the dollarization of accounts receivable pending invoicing. See note 34. The aforementioned trade and non-trade concepts, while included in the model to determine impairment losses (see Note 3.g.3), have no greater impact at the close of December 31, 2022 and 2021 due to the nature of these items: invoices not yet issued, invoices not yet due, or past due invoices within normal business ranges. a.2) Assignment of rights and sale of accounts receivable from customers I. Distribution Segment • On December 28, 2020, Enel Distribución Chile and the Inter-American Investment Corporation entered into a framework agreement by virtue of which Enel Distribución Chile will have the right to assign collection rights from time to time, including a portion of accounts receivable from energy sales to certain customers. As of December 31, 2022, collection rights were assigned for ThCh $265,929,804 (ThCh $324,134,944 as of December 31, 2021). According to the accounting criteria described in note 3.g.6, cash inflows have led to the derecognition of accounts receivable and the recognition of finance costs of ThCh $9,535,442 (ThCh $5,872,765 as of December 31, 2021). As indicated above, Enel Distribución Chile can continue to make new transfers of collection rights from time to time. The completion of additional transfers of collection rights will depend on Management’s analysis and ongoing evaluation of the cash needs and market conditions. ​ II. Generation Segment • On January 20, 2021, our subsidiaries Enel Generación Chile and Enel Green Power Chile signed a document called “Joinder”, whereby they became parties to the “Commitment and Engagement Letter” dated December 31, 2020, which is subject to foreign governing law. The “Commitment and Engagement Letter” was entered into by Goldman Sachs & Co. LLC and Goldman Sachs Lending Partners LLC, among others. Subsequently, on January 29, 2021, Enel Generación Chile and Enel Green Power Chile entered into a “Commitment Agreement” (also subject to foreign governing law), with the Inter-American Investment Corporation. The purpose of these agreements is to regulate the terms and conditions for the sale and assignment, by Enel Generación Chile and Enel Green Power Chile of balances generated in their favor (the “Balances”) by applying the transitional electricity price stabilization mechanism to customers who are subject to tariff rate regulation, as established by Law No. 21,185. Pursuant to the terms and conditions established in the “Sale and Purchase Agreement” (also subject to foreign governing law), entered into and between Enel Generación Chile S.A., Enel Green Power Chile and Chile Electricity PEC SpA., assignments of Balances may be performed by Enel Generación Chile and Enel Green Power Chile from time to time, in favor of Chile Electricity PEC SpA, an unrelated entity which was specifically incorporated for this purpose. In addition, on January 29, 2021, Enel Generación Chile and Enel Green Power Chile entered into an agreement (subject to foreign governing law) with Chile Electricity PEC SpA referred to as the “Sale and Purchase Agreement” for the sale and assignment of Balances. By virtue of this agreement, Enel Generación Chile and Enel Green Power Chile have agreed to sell and assign to Chile Electricity PEC two groups of Balances for a nominal value of approximately US$158.9 million (ThCh$115,867,879) and US$12.2 million (ThCh$8,666,252) for Enel Generación and Enel Green Power Chile, respectively, totaling ThCh$121,652,067. The sale and assignment of these groups of Balances was effected on February 8, 2021, and March 31, 2021, respectively. In addition, on June 18, 2021, Enel Generación Chile and Enel Green Power Chile entered into amendments to the aforementioned “Commitment Agreements” entered into with the Inter-American Investment Corporation. The main purpose of these amendments is to recognize new groups of Balances that the companies may sell and assign to Chile Electricity PEC SpA, as well as to make adjustments to reflect the incorporation of a third financing provider to Chile Electricity PEC SpA. Likewise, on June 21, 2021, Enel Generación Chile, Enel Green Power Chile, Goldman Sachs & Co. LLC and Goldman Sachs Lending Partners LLC, among others, agreed to modify the aforementioned “Commitment and Engagement Letter”, to reflect the incorporation of certain entities of the Allianz Group as holders of promissory notes issued by Chile Electricity PEC SpA. On June 21, 2021, Enel Generación Chile, Enel Green Power Chile, and some entities of the Allianz Group signed a “Fee Letter”, detailing the commitments assumed by the Allianz Group entities to provide financing to Chile Electricity PEC SpA, among other matters, including its amendments. On the same date, Enel Generación Chile, Enel Green Power Chile, and Chile Electricity PEC SpA amended the aforementioned “Sale and Purchase Agreements” in order to regulate the terms and conditions of future sales of Balances that Enel Generación Chile and Enel Green Power Chile may decide to effect. Detail of sales and disposals: - - - As a result of the sale and assignment of Balances as of December 31, 2022, Enel Generación Chile and Enel Green Power Chile recognized finance costs of ThCh$12,623,444 and ThCh$1,033,564, respectively (as of December 31, 2021, ThCh$39,919,437 and ThCh$3,458,695, respectively). As mentioned above, Enel Generación Chile and Enel Green Power Chile may continue to make new sales of Balances from time to time. Whether or not these sales materialize will depend on the analysis that Management performs of the cash needs and prevailing market conditions from time to time. In addition, in 2022, short-term accounts receivable were sold, which are not related to PEC balances. Enel Generación Chile and Enel Green Power Chile sold and assigned accounts receivable for a nominal amount of ThCh$955,342,410 and ThCh$21,395,481, respectively (ThCh$572,123,608 and $0, respectively, as of December 31, 2021), recognizing a financial cost of ThCh$8,226,102 and ThCh$208,364 (ThCh$682,389 and $0, respectively, as of December 31, 2021). For the year ended December 31, 2022, the effects of the aforementioned finance costs on the Distribution and Generation segments totaled ThCh$31,626,916 (ThCh$49,933,286 and ThCh$533,615 as of December 31, 2021 and 2020) (see Note 34). a.3) Others There are no restrictions on the disposal of these types of accounts receivable in a significant amount. The Group has one customer in the generation segment whose sales represent 10% or more of its revenue for the years ended December 31, 2022 and 2021: - Compañía General de Electricidad S.A.

This increase is due to the increase in accounts receivable from customers and, as a consequence, the expected credit loss. (2) See note 5.2. Write-offs of doubtful accounts The write-off of doubtful accounts is performed once all collections proceedings have been exhausted, including judicial proceedings, and proof of the debtors’ insolvency has been obtained. In the case of the Company’s Generation Business, the process normally considers at least one year of proceedings. In the Company’s Distribution Business, the process takes less than 24 months. Overall, the risk of uncollectability and, therefore, the write-off of the Company’s customers, is limited.

According to the Group Management’s estimates and projections, the expected future cash flows projections attributable to the cash-generating units or groups of cash-generating units, to which the acquired goodwill has been allocated, allow the recovery of its carrying amount as of December 31, 2022 and 2021 (see Note 3.e). The origin of the goodwill is detailed below: 1. Enel Colina S.A On December 31, 1996, Enel Distribución Chile S.A acquired 100% of Empresa Eléctrica de Colina Ltda. (currently Enel Colina S.A.) from Inversiones Saint Thomas S.A., a company that is neither directly or indirectly related to Enel Distribución Chile S.A. 2. Enel Distribución Chile S.A. On November 2000, Enersis S.A. (currently Enel Américas S.A.) acquired through a public tender offer, an additional ownership interest of 25.4% in Enel Distribución Chile S.A., reaching 99.99% ownership. 3. Enel Transmisión Chile S.A. (see Note 5.2) Enel Transmisión Chile S.A. was incorporated on January 1, 2021, as a result of the spin-off of Enel Distribución Chile S.A., and it was assigned the assets and liabilities associated with the electric power transmission business. The spin-off process was performed to comply with requirements related to the exclusive distribution business, in accordance with the latest amendments to Decree Law No. 4/2016 issued by the Ministry of Economy, Development and Reconstruction. Enel Chile maintained a goodwill arising from the Cash-Generation Unit (CGU) of Enel Distribución Chile S.A. until December 31, 2020. However, as a result of these new regulations and the emergence of a new CGU in the transmission business in 2020, a redistribution of this goodwill was performed using the value in use method as of the 2020 year-end as reference. On October 21, 2022, Enel Chile completed the sale of its subsidiary Enel Transmisión Chile S.A. to Sociedad Transmisora Metropolitana SpA., through a takeover bid. Consequently, control of Enel Transmisión Chile S.A. was transferred to the new controlling parent Sociedad Transmisora Metropolitana SpA. (see Notes 2.4.1.v and 33). 4. Enel Generación Chile S.A. On May 11, 1999, Enersis S.A. (currently Enel Américas S.A.) acquired an additional 35% ownership interest in Empresa Nacional de Electricidad S.A. (currently Enel Generación Chile S.A.) achieving 60% ownership of the generation company, through a public tender offer in the Santiago Stock Exchange and the purchase of shares in the United States (30% and 5%, respectively). On October 1, 2019, Gasatacama Chile S.A. merged with Enel Generación Chile S.A., with the latter being the legal surviving company. The resulting goodwill was recognized in Enel Generación Chile S.A. 4.1 GasAtacama Chile S.A. (ex Inversiones GasAtacama Holding Limitada) On April 22, 2014, Empresa Nacional de Electricidad S.A. (currently Enel Generación Chile S.A.) acquired 50% ownership interest in GasAtacama Chile S.A. (formerly Inversiones GasAtacama Holding Limitada), previously held by Southern Cross Latin América Private Equity Fund III L.P. 4.2. GasAtacama Chile S.A. (formerly Empresa Eléctrica Pangue S.A.) On July 12, 2002, Empresa Nacional de Electricidad S.A. (currently Enel Generación Chile S.A.) acquired 2.51% of the shares of Empresa Eléctrica Pangue S.A., upon exercise of the sale option by the minority shareholder International Finance Corporation (IFC). On May 2, 2012, Empresa Eléctrica Pangue S.A. merged with Compañía Eléctrica San Isidro S.A., with the latter being the legal surviving company. 4.3. GasAtacama Chile S.A. (formerly Compañía Eléctrica San Isidro S.A.) On August 11, 2005, Empresa Nacional de Electricidad S.A. (currently Enel Generación Chile S.A.) acquired an ownership interest in Inversiones Lo Venecia Ltda., whose sole asset was a 25% interest in San Isidro S.A. On September 1, 2013, Compañía Eléctrica San Isidro S.A. merged with Endesa Eco S.A., with the latter being the legal surviving company. On November 1, 2013, Endesa Eco S.A. merged with Compañía Eléctrica Tarapacá S.A., with the latter being the legal surviving company. On November 1, 2016, Celta merged with GasAtacama Chile S.A., with the latter being the legal surviving company. 5. Enel Green Power Chile S.A. On March 26, 2013, Enel Green Power Chile S.A. acquired ownership interest in Parque Eólico Talinay Oriente S.A. In addition, on August 6, 2001, Enel Green Power Chile S.A. acquired interests on the companies Empresa Eléctrica Panguipulli S.A. and Empresa Eléctrica Puyehue S.A., where subsequently Puyehue merged into Panguipulli and the latter became the legal successor company. On July 1, 2020, Empresa Eléctrica Panguipulli S.A. was absorbed by Parque Eólico Taltal SpA and the latter became the legal successor company. On August 1, 2020, Parque Eólico Taltal SpA merged with Almeyda Solar SpA and the latter became the legal successor. Finally, on January 1, 2021, Almeyda Solar SpA merged with Enel Green Power Chile S.A. and the latter became the legal successor company. ​

This includes: (i) Progress on the construction of the Los Cóndores Hydroelectric power plant, by Enel Generación Chile, which will use the resources from the Maule Lake and will have an installed capacity of approximately 150 MW. The carrying amount recorded in assets for this project was ThCh $919,548,128 and ThCh $790,358,312 , as of December 31, 2022 and 2021, respectively. (ii) Progress on the Cerro Pabellón, Sol de Lila, Domeyko, Valle del Sol, Campos del Sol, Sierra Gorda Solar, El Manzano and La Cabaña projects, which together represent an installed capacity of approximately 1.35 GW, and which are being executed by Enel Green Power Chile. The carrying amount recorded in assets for this project was ThCh $1,801,784,315 and ThCh $1,092,094,271 , as of December 31, 2022 and 2021, respectively. Following the accounting criteria described in Note 3.a), only those investments made in the abovementioned generation projects qualify as assets suitable for capitalizing interest. As a whole, these projects represent cumulative cash disbursements in the amount of ThCh$2,233,139,570 and ThCh$1,675,012,361, as of December 31, 2022 and 2021 respectively. b) Capitalized cost b.1) Capitalized financial expenses in work-in-progress The capitalized cost for financial expenses amounted to ThCh$83,292,276 as of December 31, 2022, (ThCh$61,513,684 and ThCh$33,109,819 as of December 31, 2021 and 2020, respectively) (see Note 34). The average financing rate ranged between 5.93% and 6.17% as of December 31, 2022 (6.86% and 7.39% as of December 31, 2021). The increase in interest capitalization evidenced during 2022 is mainly explained by an improved performance of non-conventional renewable energy projects and by a greater continuity in the performance of the Los Cóndores project. With respect to the Los Cóndores project, given the difficulties inherent to a project of this magnitude and the impacts related to COVID-19, which implied some suspensions in the execution of the project during the previous years, an update of the project schedule provided by Enel Generación Chile on July 27, 2020, estimates that it will be completed in the last quarter of 2023. b.2) Capitalized personnel expenses in work-in-progress The capitalized cost for personnel expenses directly related to constructions in progress was ThCh$44,569,685, ThCh$31,157,196 and ThCh$25,539,316 as of December 31, 2022, 2021 and 2020 respectively. The increase in the capitalization of interest and personnel expenses in fiscal years 2022 and 2021 is mainly due to a improved performance of non-conventional renewable energy projects. c) Other information (i) As of December 31, 2022 and 2021, the Group maintained commitments to acquire tangible fixed assets in the amount of ThCh $36,236,061 and ThCh $119,301,305 , respectively. (ii) As of December 31, 2022 and 2021, Enel Chile had no property, plant or equipment pledged as collateral for liabilities. (iii) The Group and its consolidated entities have insurance contracts with policies that cover any risk, earthquake and machinery breakdown up to a limit of €1,000 million (ThCh $909,243,650 ), and this coverage includes damages due to business disruption. Additionally, the Group has civil liability insurance policies for third-party claims up to a limit of €400 million (ThCh$363,697,460) in case these claims are due to the rupture of any dams owned by the Company or its subsidiaries, as well as environmental civil liability to cover environmental damage claims up to €20 million (ThCh$18,184,873). The premiums associated with these policies are recorded proportionally to each company in the caption prepaid expenses. (iv) Decarbonization plan Development during 2019: On June 4, 2019, the Company’s subsidiaries Enel Generación Chile and Gasatacama Chile entered into an agreement by which both companies, in line with their own sustainability strategy and strategic plan, and the Ministry of Energy, regulated how they would proceed to progressively eliminate the Tarapacá, Bocamina I and Bocamina II coal-fired generation units (hereinafter, Tarapacá, Bocamina I and Bocamina II). The agreement is subject to the condition precedent that the regulations on capacity transfers between generation companies go into force, which establishes, among other things, the essential conditions to ensure non-discriminatory treatment among the generators and to define the State of Strategic Reserve. By virtue of the above, Enel Generación Chile and Gasatacama Chile would formally and irrevocably agree to the final withdrawal of Bocamina I and Tarapacá, respectively, from the National Electricity System, establishing their deadlines on May 31, 2020 for Tarapacá, and December 31, 2023 for Bocamina I. The Group stated its intention to accelerate the withdrawal of Tarapacá and Bocamina I, promoting the termination of their operations, all fully coordinated with the Authority. Within this context, on June 17, 2019, Gasatacama Chile submitted a request to the CNE to perform the final withdrawal, disconnection, and termination of operations of Tarapacá at an earlier date, i.e., by December 31, 2019. On July 26, 2019, by Exempt Resolution No. 450 and in accordance with the provisions of article 72 -18 of the General Law of Electricity Services, the CNE authorized the final withdrawal, disconnection, and termination of operations of Tarapacá on December 31, 2019. The management of the Tarapacá and Bocamina I assets will be carried out separately, and these assets will not form part of the Cash-Generating Unit formed by the rest of the plants owned by the Enel Generación Chile Group, whose economic management is performed in an integrated manner. Due to the abovementioned and as a result of impairment testing on an individual basis, in 2019 the Group recognized impairment losses in the amount of ThCh$197,188,542 and ThCh$82,831,721 to adjust the carrying amount of the capitalized investment in Tarapacá and Bocamina I, respectively, to their recoverable amount. The resulting recoverable amount, after the recorded impairment, corresponds to the value of the lands held in Tarapacá and Bocamina I, in the amount of ThCh$1,613,803 and ThCh$ 6,362,581, respectively. With respect to Bocamina II, Enel Generación Chile set a goal for its early withdrawal by December 31, 2040, at the latest. All of the above was subject to the authorization established in the General Law of Electricity Services. The financial effects would depend on the factors involved in the electricity market behavior, such as fuel prices, hydrological conditions, the growth of electricity demand, and international inflation indexes, which could not be determined at the close of 2019. Notwithstanding the above, the useful lives of the Bocamina II assets were adjusted such that in any case, the depreciation would be calculated for any useful lives beyond December 31, 2040. This measure implied the recognition of a higher depreciation of ThCh$4,083,855 during 2019. Development during 2020: On May 27, 2020, the Board of Directors of Enel Generación Chile approved, subject to the corresponding CNE authorizations, the early withdrawal of Bocamina I and Bocamina II, establishing deadlines for such withdrawals on December 31, 2020, and May 31, 2022, respectively. The corresponding request was communicated to the CNE that same day. This decision shows the Company’s commitment to fight against climate change and also considered the deep changes being experienced by the industry, including the constant and increasing penetration of renewable energies and the reduction in commodities prices, making gas-powered production more competitive, which would give greater flexibility to the system’s operations in comparison to coal-fired production. On July 3, 2020, the CNE issued Exempt Resolution No. 237 authorizing the final withdrawal, disconnection, and termination of operations of Bocamina I on December 31, 2020. Regarding Bocamina II, the Group also intended to accelerate its early closure, promoting the discontinuation of its operations in strict coordination with the Authority. In this context, on July 23, 2020, the CNE issued Exempt Resolution No. 266 authorizing the final withdrawal, disconnection, and termination of operations of Bocamina II as of May 31, 2022. As occurred in 2019 with Tarapacá and Bocamina I, Bocamina II’s Management assets will be managed separately and, accordingly, these assets will not form part of the Cash-Generating Unit conforming of the rest of the plants owned by the Enel Generación Chile Group, whose economic Management continues to be carried out in a centralized manner. Consequently, and as a result of impairment testing on an individual basis, in 2020 the Group recorded an impairment loss of ThCh$697,856,387 to adjust the carrying amount of the capitalized investment in Bocamina II to its recoverable value. Additionally, for this same reason, during fiscal year 2021 the Group recorded an additional impairment loss of ThCh$28,773,083. The resulting recoverable value, after the impairment recorded, corresponds to the value of the land associated with this plant, which as of December 31, 2020, was ThCh$2,014,684. These situations have effects on deferred taxes, which are disclosed in Note 19.b. Development during 2022: On May 3, 2022, the National Energy Commission issued Exempt Resolution No. 325, which based on technical studies and system operation projections, ordered Enel Generación Chile S.A. (“Enel Generación”) to perform the final removal, disconnection, and termination of operations at the Bocamina II generation unit beginning on September 30, 2022, in accordance with article 72-18 of the General Law of Electricity Services. (v) The Company has undertaken an in-depth analysis of its project portfolio, as part of its strategy for decarbonization and to improve relations with local communities. It has considered the current conditions that are prevalent in its increasingly competitive market, with a growing investment in non-conventional renewable energies. As a result, at the end of 2022, the Group decided to abandon certain projects. This is the reason why Enel Generación Chile had to write off assets for ThCh $22,912,146 , which were mainly associated with thermal and hydroelectric projects, including the “Quintero” and “Vallecito” projects. Likewise, Enel Green Power Chile had to write off ThCh $29,887,851 associated with a geothermal project called “El Tatio”, which was being developed in the Antofagasta region (See Note 32). (vi) As of September 2020, the Company’s subsidiary Empresa Nacional de Geotermia recorded an impairment of its works in progress of ThCh $378,993 . Subsequently, its liquidation process began in December 2020, and was finalized during the second half of 2021. ​

(ii) This item corresponds to a reclassification of balances, from Deferred Tax Assets to Recoverable Taxes, due to a higher tax expense for the purposes of closing the 2022 tax return. This higher tax expense is related to higher write-off of trade receivables. The documentation that guarantees tax compliance with these trade receivables was completed during the first quarter of this year. Recovery of deferred tax assets will depend on whether sufficient taxable profits are obtained in the future. The Company’s Management believes that the future profit projections for its subsidiaries will allow these assets to be recovered. As of December 31, 2022 and 2021, the Group has accounted for all deferred tax assets associated with its tax losses (See Note 3.p). Concerning temporary differences related to investments in consolidated entities and certain joint ventures, the Group has not recognized deferred tax liabilities associated with undistributed profits, in which the position of control exercised by the Group over such consolidated entities allows it to manage the time of their reversal, and it is estimated that they will not be reversed in the near future. The total amount of these taxable temporary differences, for which no deferred tax liabilities have been recognized as of December 31, 2022, amounts to ThCh$1,029,815,247 (ThCh$1,232,849,769 as of December 31, 2021). Additionally, no deferred tax assets have been recorded in relation to the deductible temporary differences associated with investments in consolidated entities and certain joint ventures. Such temporary differences are not expected to be reversed in the foreseeable future or tax gains will not be available for their use. As of December 31, 2022, such deductible temporary differences amount to ThCh$1,373,836,286 (ThCh$1,433,966,263 as of December 31,2021). The Group companies are potentially subject to income tax audits by the tax authorities of each country in which the Group operates. Such tax audits are limited to a number of annual tax periods and once these have expired, audits of these periods can no longer be performed. Tax audits by nature are often complex and can require several years to complete. Tax years potentially subject to examination are 2018 to 2021. Given the range of possible interpretations of tax standards, the results of any future inspections carried out by tax authorities for the years subject to audit can give rise to tax liabilities that cannot currently be quantified objectively. Nevertheless, the Company’s Management estimates that the liabilities, if any, that may arise from such audits, would not significantly impact the Group companies’ future results. The effects of deferred taxes on the components of other comprehensive income attributable to both controlling and non-controlling interests for the years ended December 31, 2022, 2021 and 2020, are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2022 ​ 2021 ​ 2020 Deferred Income Tax Effects on the Components of Other Comprehensive Income Amount Before Tax Income Tax Expense (Benefit) Amount After Tax Amount Before Tax Income Tax Expense (Benefit) Amount After Tax Amount Before Tax Income Tax Expense (Benefit) Amount After Tax ​ ​ ThCh$ ​ ThCh$ ​ ThCh$ ​ ThCh$ ​ ThCh$ ​ ThCh$ ​ ThCh$ ​ ThCh$ ​ ThCh$ Financial assets at fair value with movements in other comprehensive income ​ (2) ​ 1 ​ (1) ​ 31 ​ (8) ​ 23 ​ (9,125) ​ 2,464 ​ (6,661) Cash flow hedge ​ 147,505,497 ​ (39,826,484) ​ 107,679,013 ​ (406,971,212) ​ 109,882,227 ​ (297,088,985) ​ 267,540,328 ​ (72,741,119) ​ 194,799,209 Share of other comprehensive income from associates and joint ventures accounted for using the equity method ​ 1,043,185 ​ — ​ 1,043,185 ​ 359,797 ​ — ​ 359,797 ​ 18,982 ​ — ​ 18,982 Foreign currency translation ​ 18,994,934 ​ — ​ 18,994,934 ​ 197,099,813 ​ — ​ 197,099,813 ​ (69,218,245) ​ — ​ (69,218,245) Actuarial gains(losses) on defined-benefit pension plans ​ (7,304,757) ​ 1,972,561 ​ (5,332,196) ​ 12,547,898 ​ (3,387,932) ​ 9,159,966 ​ (8,545,834) ​ 2,308,510 ​ (6,237,324) Income tax related to components of other income and expenses with a charge or credit in equity ​ 160,238,857 ​ (37,853,922) ​ 122,384,935 ​ (196,963,673) ​ 106,494,287 ​ (90,469,386) ​ 189,786,106 ​ (70,430,145) ​ 119,355,961 ​ The following table shows the reconciliation of deferred tax movements between balance sheet and income taxes in other comprehensive income as of December 31, 2022, 2021 and 2020: ​ ​ ​ ​ ​ ​ ​ ​ ​ For the years ended December 31, ​ 2022 2021 2020 Deferred taxes of components of other comprehensive income ​ ThCh$ ​ ThCh$ ​ ThCh$ Total increases (decreases) for deferred taxes of other comprehensive income from continuing operations ​ 1,972,562 ​ (3,387,940) ​ 1,923,974 Income tax of movements in cash flow hedge transactions ​ (39,826,484) ​ 109,882,227 ​ (72,354,119) Total income tax relating to components of other comprehensive income ​ (37,853,922) ​ 106,494,287 ​ (70,430,145) ​

RISK MANAGEMENT POLICY
Risk Management Policy	22. RISK MANAGEMENT POLICY The Group companies follow the guidelines of the Risk Management Control System (SCGR) defined at the Holding level (Enel S.p.A.), which establishes rules for managing risks through the respective standards, procedures, systems, etc., applicable to the different levels of the Group companies, in the business risk identification, analysis, evaluation, treatment, and communication processes the business addresses on a continuous basis. These guidelines are approved by the Enel S.p.A. Board of Directors, which includes a Risk and Controls Committee responsible for supporting the Enel Chile Board’s evaluation and decisions regarding internal control and risk management system, as well as those related to the approval of periodic financial statements. To comply with the guidelines, each company has its own specific Control Management and Risk Management policy, which is reviewed and approved at the beginning of each year by the Enel Chile Board of Directors, observing and applying all local requirements in terms of the risk culture. The Company seeks protection against all risks that could affect the achievement of the business objectives. The Enel Group has a risk taxonomy for the entire Group which considers 6 risk macro-categories: financial; strategic; governance and culture; digital technology; compliance; and operational; and 38 risk sub-categories to identify, analyze, assess, evaluate, treat, monitor and communicate their risks. The Enel Group risk management system considers three lines of action (defense) to obtain effective and efficient risk management and controls. Each of these three “lines” plays a different role within the organization’s broader governance structure (Business and Internal Control areas acting as the first line, Risk Control as the second line, and Internal Audit as the third line of defense). Each line of defense has the obligation to report to and keep senior management and the Directors up-to-date on risk management. In this sense, the first and second lines of defense report to the senior management, and the second and third lines report to the Directors. Within each of the Group’s companies, the risk management is decentralized. Each manager responsible for the operating process in which the risk arises is also responsible for treating the risk and adopting risk control and mitigating measures. 22.1 Interest rate risk Changes in interest rates affect the fair value of assets and liabilities bearing fixed interest rates, as well as the expected future cash flows of assets and liabilities subject to floating interest rates. The objective of managing interest rate risk exposure is to achieve a balance in the debt structure to minimize the cost of debt with reduced volatility in profit or loss. The Group’s financial debt structure per fixed and/or hedged interest rate on gross, net of hedging derivative instruments engaged, is as follows: ​ ​ ​ ​ ​ ​ ​ ​ For the years ended December 31, ​ 2022 2021 ​ ​ % ​ % Fixed interest rate ​ 84% ​ 82% ​ This ratio only considers debt transactions between third parties and Enel Finance International, if any. Depending on the Group’s estimates and the objectives of the debt structure, hedging transactions are performed by entering into derivative contracts to mitigate these risks. Risk control through specific processes and indicators allows companies to limit possible adverse financial impacts and, at the same time, optimize the debt structure with an adequate degree of flexibility. It is public knowledge that LIBOR will be gradually discontinued by June 30, 2023, and the market consensus is that it will be substituted by the SOFR reference rate, which is a risk-free rate. The Enel Chile Group has analyzed the potential impacts of this reform, which includes an identification of the contracts affected, an analysis of relevant clauses, and a work plan to adapt and update the documentation to new market standards. Additionally, in order to anticipate for this reform, all new financial operations signed by Enel Chile have been governed by the new SOFR reference interest rate. However, this does not eliminate some potential risks inherent to the new reference rate adaptation process, such as a potential increase or decrease in the post-change interest rate, risk related to the availability of new rate data, operational risk derived from the need to adapt our new systems to the new reference, etc. As of December 31, 2022, our total exposure to LIBOR debt is US$ 540 million (ThCh$462,164,400) and includes allowances for the transition from LIBOR to an alternative reference rate. Additionally, we have coverage through derivative instruments that reference LIBOR and mature after June 2023, in the amount of US$ 50 millions (ThCh$42,793,000), considering transition provisions according to the market standard. 22.2 Exchange rate risk Exchange rate risks involve basically the following transactions: - Debt taken on by the Group’s companies that is denominated in a currency other than the currency in which its cash flows are indexed. - Payments to be made in a currency other than the one to which its cash flows are indexed, for example, for the acquisition of materials associated with projects and payments of corporate insurance policies, among others. - Income in Group companies directly linked to changes in currencies other than the currency of its cash flows. In order to mitigate foreign currency risk, the Group’s foreign currency risk management policy is based on cash flows and includes maintaining a balance between U.S. dollar flows and the levels of assets and liabilities denominated in such currency. The objective is to minimize the exposure to variability in cash flows that are attributable to foreign exchange risk. The hedging instruments currently being used to comply with the policy are currency swaps and forward exchange contracts. During the fourth quarter of 2022, exchange rate risk management continued in the context of complying with the aforementioned risk management policy, without difficulty to access the derivatives market. 22.3 Commodities risk The Group has a risk exposure to price fluctuations in certain commodities, basically due to: - - Purchases of fuel used to generate electricity. - - Energy purchase/sale transactions that take place in local markets. To reduce the risk in situations of extreme drought, the Group has designed a commercial policy that defines the levels of sales commitments in line with the capacity of its generating power plants in a dry year. It also includes risk mitigation terms in certain contracts with unregulated customers and with regulated customers subject to long-term tender processes, establishing indexation polynomials that allow for reducing commodities exposure risk. Considering the operating conditions faced by the power generation market, with drought and highly volatile commodity prices on international markets, the Company is constantly evaluating the use of hedging to minimize the impacts that these price fluctuations have on its results. As of December 31, 2022, there were Brent hedges on purchases for 450 Kbbl to be settled in 2023. There were also two hedges on gas commodities: a) the 2.7 TBtu HH Swap on sales to be settled in 2023; and b) the 18.9 TBtu HH Future on purchases to be settled in 2023. There was also a hedge on purchases of 175.6 kTon of coal to be settled in 2023. As of December 31, 2021, there were Brent hedges on 1,930 Kbbl to be settled in 2022 and HH hedges on 9.1 TBtu to be settled in 2022. Depending on the Group’s permanently updated operating conditions, these hedges may be modified, or include other commodities. Thanks to the mitigation strategies implemented, the Group was able to minimize the effects of the volatility of commodity prices on the results of the fourth quarter of 2022. 22.4 The Group maintains a liquidity risk management policy that consists of entering into long-term committed banking facilities and temporary financial investments for amounts that cover the projected needs over a period of time that is determined based on the situation and expectations for debt and capital markets. Despite having negative working capital at the end of 2022, the Company has the capacity to overcome this situation and mitigate the risk through its liquidity risk policy and actions described herein. The projected needs mentioned above include maturities of financial debt net of financial derivatives. For further details regarding the features and conditions of financial obligations and financial derivatives see Notes 20, 21 and 23. As of December 31, 2022, the Group recorded liquidity in the amount of ThCh$875,213,699 in cash and cash equivalents and ThCh$333,551,000 in unconditionally available long-term lines of credit. As of December 31, 2021, the Group recorded liquidity of ThCh$309,975,140 in cash and cash equivalents and ThCh$118,469,000 in unconditionally available long-term lines of credit. 22.5 Credit risk The Group closely monitors its credit risk. Trade receivables: Regarding the credit risk of our electricity generation line of business, related to trade receivables, this risk is historically very limited because the customer collection period is short, accordingly, no significant individual amounts are accumulated before the service is shut-off due to late payment, according to contract conditions. For this reason, credit risk is continuously monitored, measuring the maximum amounts exposed to payment risk which is very limited. For our electricity distribution company, it has the power to shut-off supply in the event of customer default, which is applied in accordance with current regulations and facilitates the process to evaluate and control credit risk, which is also limited. However, on August 8, 2020, Law 21,249 on Basic Services was published and during 2021 two extensions to this Law 21,249 were published, which provide exceptional measures on behalf of end users of water, electricity and gas services. The regulation established, up to December 31, 2021, the prohibition to shut off services for residential customers (as well as hospitals, healthcare centers, orphanages and retirement homes, non-profit organizations, micro companies, among others). In February 2022, Law No. 21,423 established a payment schedule for all debts arising from the application of Law No. 21. 249 and its extensions, i.e., for debts incurred in the period March 18, 2020, through December 31, 2021, for customers with an average 2021 consumption of less than 250 kWh and who have debt from the period indicated above through February 11, 2022, through which each customer will receive a subsidy in 48 equal monthly installments, with a maximum limit equivalent to 15% of their average monthly billing for the year 2021. The debt balance that cannot be covered in 48 installments will be absorbed in part (50%) by the company, and the rest will be applied to distribution rates in the pricing process after the 48 installments (installment 49). The collection system started on August 1, 2022. According to circular No. 140129 of September 30, 2022, the customer no longer completely loses its subsidy if its account is not up-to-date, but will lose the monthly subsidy when the account has not been paid 45 days after the due date of the first document in which the subsidy was charged. Therefore, only the proportional installment will be charged as the previous balance until the customer's situation is corrected. The Group's portfolio shows, to date, resilience in the face of the global pandemic crisis. This is due to strengthening digital collection channels and solid diversification of commercial customers that have had low exposure to the impact of COVID. Financial assets: Cash surpluses are invested in the highest-rated local and foreign financial thresholds established for each entity. Banks that have received investment grade ratings from the three major international rating agencies (Moody’s, S&P, and Fitch) are selected for making investments. Investments may be supported through Chilean treasury bonds and/or commercial paper issued by the highest rated banks; the latter are preferable as they offer higher returns (always in line with current investment policies). 22.6 Risk measurement The Group measures the Value at Risk (VaR) of its debt positions and financial derivatives in order to monitor the risk assumed by the Company, thereby reducing volatility in the income statement. The portfolio of positions included for purposes of calculating the present VaR include: - Financial debt. - Hedging derivatives for debt. The VaR determined represents the potential variation in value of the portfolio of positions described above in a quarter with a 95% confidence level. To determine the VaR, we take into account the volatility of the risk variables affecting the value of the portfolio of positions, including: - The exchange rates of the various currencies used in the calculation. The calculation of VaR is based on generating possible future scenarios (at one quarter) of market values of the risk variables based on scenarios based on real observations for the same period (at one quarter) during five years. The quarter 95% confidence VaR number is calculated as the 5% percentile most adverse of the quarterly possible fluctuations. Taking into consideration the assumptions previously described, the quarter VaR of the previously discussed positions was ThCh$602,754,498. This value represents the potential increase of the Debt and Derivatives’ Portfolio, thus these VaR are inherently related, among other factors, to the Portfolio’s value at each quarter end. ​

This enables the adoption of new work and operation models and demands new skills and knowledge to make processes even more efficient. The expected timing and amount of any cash outflows related to the above provisions is uncertain and depends on the resolution of specific matters related to each one. For example, specifically for litigation, this depends on the final resolution of the corresponding legal claim. Management believes that provisions recognized in the financial statements cover the related risks appropriately. b) Movements in provisions as of December 31, 2022 and 2021 , are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Legal Proceedings Decommissioning or Restoration Environmental Issues and Other Provisions Total Movements in Provisions ​ ThCh$ ​ ThCh$ ​ ThCh$ ​ ThCh$ Balance as of January 1, 2022 ​ 14,414,328 ​ 186,716,459 ​ 12,738,244 ​ 213,869,031 Increase (decrease) in existing provisions (1) ​ 11,224,282 ​ 11,059,100 ​ (1,697,843) ​ 20,585,539 Provisions used ​ (7,178,867) ​ (16,548,540) ​ (7,250,696) ​ (30,978,103) Reversal of unused provision ​ (1,300,906) ​ — ​ — ​ (1,300,906) Increase from adjustment to time value of money (2) ​ — ​ 11,338,594 ​ — ​ 11,338,594 Conversion Difference Foreign Currency Exchange ​ (54,278) ​ (72,347) ​ 8,032 ​ (118,593) Other Increase (Decrease) (3) ​ — ​ (481,429) ​ (541,884) ​ (1,023,313) Total movements in provisions ​ 2,690,231 ​ 5,295,378 ​ (9,482,391) ​ (1,496,782) Balance as of December 31, 2022 ​ 17,104,559 ​ 192,011,837 ​ 3,255,853 ​ 212,372,249 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Legal Proceedings Decommissioning or Restoration Environmental Issues and Other Provisions Total Movements in Provisions ​ ThCh$ ​ ThCh$ ​ ThCh$ ​ ThCh$ Balance as of January 1, 2021 ​ 16,335,174 ​ 191,867,939 ​ 5,473,362 ​ 213,676,475 Increase (decrease) in existing provisions (4) ​ 6,006,400 ​ (3,197,115) ​ 7,856,556 ​ 10,665,841 Provisions used ​ (1,999,269) ​ (2,782,780) ​ (623,019) ​ (5,405,068) Reversal of unused provision ​ (6,378,072) ​ — ​ — ​ (6,378,072) Increase from adjustment to time value of money (2) ​ — ​ (1,672,021) ​ — ​ (1,672,021) Conversion Difference Foreign Currency Exchange ​ 483,048 ​ 2,605,855 ​ 33,882 ​ 3,122,785 Other Increase (Decrease) ​ (32,953) ​ (105,419) ​ (2,537) ​ (140,909) Total movements in provisions ​ (1,920,846) ​ (5,151,480) ​ 7,264,882 ​ 192,556 Balance as of December 31, 2021 ​ 14,414,328 ​ 186,716,459 ​ 12,738,244 ​ 213,869,031 (1) As of December 31, 2022, the increase in provisions for decommissioning or restoration for the year is mainly due to the decrease in interest rates during the period.

Information by Segment

INFORMATION BY SEGMENT
Information by Segment	35. INFORMATION BY SEGMENT 35.1. Basis of segmentation The Group’s activities operate under a matrix management structure with dual and cross management responsibilities (based on business and geographical areas of responsibility), and its subsidiaries are engaged in either the generation and the distribution business. The Group adopted a “bottom-up” approach to determine its reportable segments. The generation and networks and the distribution reportable segments were defined based on IFRS 8.9 and on the criteria described in IFRS 8.12. Generation Segment: Distribution and Networks Segments: It should be noted that on December 9, 2022, the Group disposed of its interest in Enel Transmisión Chile, a company belonging to the Distribution and Networks segment until that date. Following the accounting criteria described in note 3.k), the sale of this company did not qualify as a discontinued operation. Therefore, its results up to the sale date are part of the consolidated results of Enel Chile and are included in the results of the Distribution and Networks segment detailed below (see notes 33 (1) and 40). Each of the operating segments generates separate financial information, which is aggregated into one combined set of information for the Generation Business, and another set of combined information for the Distribution and Networks Business at the reportable segment level. In addition, in order to assist the decision-making process, the Planning & Control Department at Parent Company level prepares internal reports containing combined information at the reportable segment level about the main key performance indicators (KPIs), such as: EBITDA 1 , Total Capex 2 , Profit for the Year, Total Energy Generation 3 , Distribution and Networks 4 , among others. The presentation of information under this business approach has been made taking into consideration that the KPIs are similar in each of the following aspects: a) The nature of the activities: generation on one hand, and distribution and networks on the other; b) The nature of the production processes: The Generation Business deals with the generation of electricity and its transmission to dispatch centers, while the Distribution Business does not generate electricity, but distributes electricity to end customers; c) The methods used to distribute its products or provide the services: generators normally sell energy through energy bids, whereas distributors and transmitters deliver energy in their concession area or area where their facilities operate; and d) The nature of the regulatory framework for public electricity services: the regulatory framework distinguishes between Generation companies, which can freely decide whether to sell their energy and capacity to regulated or unregulated customers; and Distribution and Networks companies, which, as natural monopolies, are subject to regulated tariffs and are required free access to their networks. The Company’s highest decision-making authority reviews on a monthly basis these internal reports and uses the KPI information to make decisions on the allocation of resources and the assessment of the performance of the operating segments for each reportable segment. The information disclosed in the following tables is based on the financial information of the companies forming each segment. The accounting policies used to determine the segment information are the same as those used in the preparation of the Group’s consolidated financial statements. 35.2 Financial information by business

Enel Distribución filed an appeal for reconsideration against this resolution, which was partially accepted, reducing the fine to 10,000 UTM (ThCh $611,570 ). On June 29, 2022, an appeal was filed before the Court of Appeals of Santiago, which is pending. 3.6. By means of Exempt Resolution No. 35,004 dated November 12, 2021, the Superintendence of Electricity and Fuels imposed on Enel Distribución a fine equivalent to 35,611 UTM (ThCh $2,177,862 ) on the basis that Enel Distribución exceeded the maximum values allowed by the current regulations in the continuity indexes at the level of the primary feeders, which constitutes a breach of the supply quality standards. Enel Distribución filed an appeal for reconsideration against this resolution, which was rejected by Exempt Resolution No. 35,282.

In relation to the litigation described above, the Enel Chile Group has recorded provisions of ThCh$6,004,761 as of December 31, 2022 (see Note 25). There are other litigation matters that also have associated provisions but are not described in this note since individually they represent immaterial amounts. Management considers that the provisions recorded adequately cover the litigation risks and, therefore, does not expect additional liabilities other than those already recorded. Given the characteristics of the risks covered by these provisions, it is not possible to determine a reasonable schedule of payment dates, if any. 36.4. Financial restrictions Several debt contracts of the Company, and of some of its subsidiaries include the obligation to comply with certain financial ratios, which is common in contracts of this nature. There are also affirmative and negative covenants that require monitoring of these commitments. In addition, there are restrictions in the sections of events of default that must be fulfilled to avoid acceleration of the debt. 1.

Financial covenants Financial covenants are contractual commitments with respect to minimum or maximum financial ratios that the Company is obliged to meet at certain periods of time (quarterly, annually, etc.) and in some cases only when certain conditions are met. Most of the financial covenants of the Company limit leverage and track the ability to generate cash flow that will service the companies’ indebtedness. Certain companies are also required to periodically certify these covenants. The types of covenants and their respective limits vary according to the type of debt and contract. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial restrictions Enel Generación Chile Enel Generación Chile Enel Generación Chile Enel Generación Chile Instrument type with restriction ​ Series H and M Bonds ​ Series H and M Bonds ​ Series H and M Bonds ​ Series H Bonds Restriction to be fulfilled by Informant or Subsidiary ​ A ratio between Financial Obligations and Total Capitalization must be maintained of less than or equal to 0.64 . ​ Maintain a Minimum Equity of Ch $761,661 million, a limit that is updated at the end of each fiscal year, as established in the contract. ​ Maintain a Financial Expense Coverage Coefficient of greater than or equal to 1.85 . ​ Maintain a Net Active Position with Related Companies not exceeding the equivalent amount in pesos, legal tender, of US $500 million, according to the exchange rate observed on the date of its calculation.

ACCOUNTING POLICIES
Property, plant and equipment	a) Property, plant and equipment Property, plant and equipment are generally measured at acquisition cost, net of accumulated depreciation and any impairment losses experienced. In addition to the price paid to acquire each item, the cost also includes the following concepts where applicable: - Finance costs accrued during the construction period that are directly attributable to the acquisition, construction, or production of qualifying assets, which require a substantial period of time before being ready for use; such as e.g., electricity generation or distribution facilities. The Group defines “substantial period” as a period exceeding twelve months. On the other hand, the capitalization of interest is suspended for periods in which the performance of activities for a qualifying asset has been interrupted, if these periods are extended over time. The interest rate used is that corresponding to the specific financing or, if it does not exist, the average financing rate of the company making the investment (see Note 16.b.1). - Employee expenses directly related to construction in progress (see Note 16.b.2). - Future disbursements that the Group will have to make to close its facilities are added to the value of the asset at fair value, recognizing the related provision for dismantling or restoration. Changes in the measurement of the provision resulting from changes in the estimated amount or timing of future expenditures required to settle the obligation, or changes in the discount rate, are added to or deducted from the cost of the asset, as appropriate (see Note 25). Assets under construction are transferred to operating assets once the testing period has been completed and they are available for use, at which time depreciation begins. Expansion, modernization or improvement costs that represent an increase in productivity, capacity or efficiency, or a longer useful life are capitalized as an increase in the cost of the related assets. The replacement or overhaul of entire components that increase the asset’s useful life or economic capacity are recorded as an increase in cost of the related assets, derecognizing the replaced or overhauled components. Expenditures for periodic maintenance and repair are recognized directly as an expense for the year in which they are incurred. Property, plant and equipment, net of its residual value, is depreciated by distributing the cost of the different items that comprise it on a straight-line basis over its estimated useful life, which is the period during which the Group expects to use the assets. Useful life estimates and residual values are reviewed on an annual basis and if appropriate adjusted prospectively. In addition, the Group recognizes right-of-use assets for leases relating to property, plant and equipment in accordance with the criteria established in Note 3.f. The following are the main categories of property, plant and equipment with their related estimated useful lives: ​ ​ ​ ​ Class of property, plant and equipment Years of estimated useful life Buildings ​ 10 – 60 Plant and equipment ​ 6 – 65 IT equipment ​ 3 – 15 Fixtures and fittings ​ 2 – 35 Motor vehicles ​ 5 – 10 In addition, for further information, the following is a more detailed breakdown of the class of plant and equipment: ​ ​ ​ Class of plant and equipment Years of estimated useful life Generating plant and equipment ​ ​ Hydroelectric plants ​ ​ Civil engineering works ​ 10 – 65 Electromechanical equipment ​ 10 – 45 Combined cycle power plants ​ 10 – 25 Renewable ​ 10 – 50 Distribution plant and equipment ​ ​ High-voltage network ​ 10 – 60 Low- and medium-voltage network ​ 10 – 50 Measuring and remote control equipment ​ 10 – 50 Primary substations ​ 6 – 25 Natural gas transportation ​ ​ Gas pipelines ​ 20 ​ Land is not depreciated since it has an indefinite useful life, unless it relates to a right-of- use asset in which case it is depreciated over the term of the lease. An item of property, plant and equipment is written off when sold or otherwise disposed of, or when no future economic benefits are expected to be obtained from its use, sale or other disposal. Gains or losses arising from sales of property, plant and equipment or PP&E items retired, are recognized as “Other gains (losses)” in the statement of comprehensive income and are determined as the difference between the sale value and net carrying amount of the asset.
Investment property	b) Investment property “Investment property” basically includes land and buildings that are kept for the purpose of obtaining gains from future sales or lease arrangements. Investment property is measured at acquisition cost, net of accumulated depreciation and any impairment losses experienced. Investment property, excluding land, is depreciated by distributing the cost of the several elements that comprise it on a straight-line basis over the years of useful life. An investment property is derecognized on disposal, or when no future economic benefits are expected from use or disposal. Gains or losses arising from the sale or disposal of items of investment property are recognized as “Other gains (losses)” in the statement of comprehensive income and determined as the difference between the sales amount and the net carrying amount of the asset.
Goodwill	c) Goodwill Goodwill arising from business combinations and reflected in consolidation, represents the excess of the value of the consideration transferred plus the amount of any non-controlling interest over the net identifiable assets acquired and liabilities assumed, measured at fair value at the date of acquisition of the subsidiary. During the measurement period of the business combination, goodwill may be adjusted as a result of changes in the provisional amounts recognized for the assets acquired and liabilities assumed (see Note 2.7.1). Goodwill arising from acquisition of companies with functional currencies other than the functional currency of the Parent Company is measured in the functional currency of the acquiree and translated to Chilean peso using the exchange rate effective as of the date of the statement of financial position. After initial recognition, goodwill is not amortized, but rather, at the end of each accounting period, or when there are indications thereof, an impairment test is performed to determine whether any impairment has occurred that reduces its recoverable value to an amount lower than the recorded net cost, and if this is the case, the impairment is recorded in the statement of income for the period (see Note 3.e).
Intangible assets other than goodwill	d) Intangible assets other than goodwill Intangible assets are initially recognized at their acquisition cost or production cost, and are subsequently measured at their cost, net of their accumulated amortization and impairment losses experienced. Intangible assets are amortized on a straight-line basis over their useful lives starting from the time they are in use, except for those assets with indefinite useful lives, for which amortization is not applicable. As of December 31, 2022, and December 31, 2021, intangible assets with indefinite useful lives amounted to ThCh$6,550,168 and ThCh$14,766,953, respectively, mainly related to easements and water rights. The decrease in these assets at the end of December 2022 is mainly due to the transfer of ThCh$ 9,377,135 to assets classified as held for sale from Enel Transmisión Chile S.A. (see Note 5.2). An intangible asset is derecognized when it is sold or otherwise disposed of, or when no future economic benefits are expected from its use, sale or other disposal. Gains or losses arising from sales of intangible assets are recognized in profit or loss for the period and determined as the difference between the amount of the sale and the carrying amount of the asset. The criteria for recognizing impairment losses on these assets and, if applicable, recoveries of impairment losses recorded in prior periods are explained in letter e) of this Note below. d.1) Research and development expenses The Group recognizes the costs incurred in a project’s development phase as intangible assets in the statement of financial position as long as the project’s technical feasibility and future economic benefits have been demonstrated. Research costs are recorded as an expense in the consolidated statement of comprehensive income in the period in which they are incurred. d.2) Other intangible assets These assets correspond mainly to computer software, water rights and easements. They are initially recognized at acquisition or production cost and are subsequently valued at cost net of the related accumulated amortization and impairment losses, if any. Computer software is amortized (on average) over four years. Certain easements and water rights have indefinite useful lives and are therefore not amortized.
Impairment of non-financial assets	e) Impairment of non-financial assets During the period, and mainly at the end of each reporting period, the Group evaluates whether there is any indication that an asset has been impaired. If any such indication exists, the Group estimates the recoverable amount of that asset to determine the amount of the impairment loss. For identifiable assets that do not generate cash flows independently, the Group estimates the recoverable amount of the Cash Generating Unit (CGU) to which the asset belongs, which is understood to be the smallest identifiable group of assets that generates independent cash inflows. Notwithstanding the preceding paragraph, for CGUs to which goodwill or intangible assets with indefinite useful lives have been allocated, a recoverability analysis is performed routinely at each year-end. The criteria used to identify the CGUs are based, in line with Management’s strategic and operating vision, within the specific characteristics of the business, the operating rules and regulations of the market in which the Group operates and corporate organization. Recoverable amount is the higher of fair value less costs of disposal and value in use, which is defined as the present value of the estimated future cash flows. In order to calculate the recoverable amount of Property, plant, and equipment, as well as of goodwill and intangible assets, at the level of each CGUs the Group uses value in use criteria in practically all cases. To estimate value in use, the Group prepares future pre-tax cash flow forecasts based on the most recent budgets available. These budgets include Management’s best estimates of a CGU’s revenue and costs using sector forecasts, past experience and future expectations. In general, these projections cover the next three years, estimating cash flows for subsequent years by applying reasonable growth rates which, in no case, are increasing rates nor exceed the average long-term growth rates for the particular sector. At the end of December 2022 and 2021, the rates used to extrapolate the projections were between 2.0% and 3.0%. These flows are discounted to calculate their present value at a pre-tax rate that includes the cost of capital of the business and the geographical zone where it is carried out. This calculation considers the current cost of money and the risk premiums used in general among analysts for the business and geographical zone. Future cash flows are discounted to calculate their present value at a pre-tax rate that covers the cost of capital for the business activity and the geographic area in which it is being carried out. The time value of money and risk premiums generally used among analysts for the business activity and the geographic zone are taken into account to calculate the pre-tax rate. The pre-tax discount rates, expressed in nominal terms, applied at the end of December 2022 were between 7.4% and 11.1% (at the end of December 2021 were between 6.0% and 7.7%). The Company’s approach to allocate value to each key assumption used to project cash flows, considers: - Demand evolution: the growth estimate has been calculated based on the projected increase in Gross Domestic Product (GDP), in addition to other assumptions used by the company regarding the evolution of consumption, such as the growth in the number of customers. - Energy purchase and sale prices: based on specifically developed internal projection models. The price of the planned “pool” is estimated by considering a number of determining factors, such as the different technology’ costs and productions and energy demand, among other items. - Regulatory measures: an important part of the Company’s business is regulated and subject to extensive standards, which could undergo revisions, either as a result of new laws or the amendment of existing laws, and therefore the projections include adequate application of the current standards, those that are currently being developed, and those expected to be effective during the projected period. - Installed capacity: in the estimating of the Group’s installed capacity, the existing facilities are taken into account, as well as the plans for both increasing capacity and capacity closure. The investment plan is constantly updated based on the evolution of the business, quality of service regulations determined by the regulator and changes in the business development strategy adopted by management. In the generation area, the investments necessary to maintain the installed capacity in adequate operating conditions are taken into account; in the distribution activity, investments for maintenance, improvement and strengthening of the network are considered, as well as the investments necessary to carry out the implementation of the technological improvement plan (Smart Meters). - Hydrology and NCRE: the projections are made from historical series of meteorological conditions and projecting an average year, based on these. - Fuel costs for the estimation of fuel costs take into consideration existing supply contracts and long-term projections of oil, gas or coal prices based on forward markets and available analysts’ estimates. - Fixed costs: these are projected considering the foreseen level of business activities, both in terms of the evolution of the workforce (considering salary raises in line with the CPI), and in term of other operating and maintenance costs, the level of projected inflation and long-term existing maintenance or other contracts. The efficiencies that the Group is adopting over time are also considered, such as those that arise from the initiatives for the digitalization of internal processes. - External sources are always considered to verify the assumptions related to the macroeconomic environment such as price evolution, GDP growth, demand, inflation, interest rates and exchange rates, among others. Past experience has demonstrated the reliability of the Company’s forecasts, which allows it to base key assumptions on historical information. During 2022, the deviations observed with respect to the projections used to perform impairment testing as of December 31, 2021, were not significant and cash flows generated in 2022 remained in a reasonable variance range compared to those expected for that period. If the recoverable amount of the CGU is less than the net carrying amount of the asset, the related impairment loss is recognized for the difference, and charged to “Impairment loss (impairment reversals) recognized in profit or loss” in the consolidated statement of comprehensive income. The impairment is first allocated to the CGU’s goodwill carrying amount, if any, and then to the other assets comprising it, prorated on the basis of the carrying amount of each one, limited to the fair value less costs of disposal, or value in use, where no negative amount could be obtained. Impairment losses recognized in prior periods for an asset other than goodwill are reversed, if and only if, there has been a change in the estimates used to determine the asset’s recoverable amount since the last impairment loss was recognized. If this is the case, the carrying amount of the asset is increased to its recoverable amount with a credit to profit or loss, but so that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset. For goodwill, impairment losses are not reversed in subsequent periods.
Leases	f) Leases In order to determine whether an arrangement is, or contains, a lease, Enel Chile assesses the economic substance of the agreement, assessing whether the agreement conveys the right to control the use of an identified asset for a period of time in exchange for consideration. Control is considered to exist if the customer has (i) the right to obtain substantially all the economic benefits arising from the use of an identified asset; and (ii) the right to direct the use of the asset. f.1) Lessee When the Group acts as a lessee at the commencement of the lease (i.e., on the date on which the underlying asset is available for use) it records a right-of-use asset and a lease liability in the statement of financial position. The Group initially recognizes right-of-use assets at cost. The cost of right-of-.use assets consist of: i) the amount of the initial measurement of the lease liability; (ii) lease payments made until the commencement date less lease incentives received, (iii) initial direct costs incurred; and (iv) the estimate of decommissioning or restoration costs. Subsequently, the right-of-use asset is measured at cost, adjusted by any remeasurement of the lease liability, less accumulated depreciation and accumulated impairment losses. A right-of-use asset is depreciated on the same terms as other similar depreciable assets, as long as there is reasonable certainty that the lessee will acquire ownership of the asset at the end of the lease. If no such certainty exists, the leased assets are depreciated over the shorter of the useful lives of the assets and their lease term. The same criteria detailed in Note 3.e are applied to determine whether the right-of-use asset has become impaired. Lease liabilities are initially measured at the present value of the lease payments, discounted at the Company’s incremental borrowing rate, if the interest rate implicit in the lease cannot be readily determined. The incremental borrowing rate is the interest rate that the company would have to pay to borrow over a similar term, and with similar security, the funds necessary to obtain an asset of similar value to the right-of-use asset in a similar economic environment. The Group determines its incremental borrowing rate using observable data (such as market interest rates) or by making specific estimates when observable rates are not available (e.g., for subsidiaries that do not engage in financing transactions) or when they must be adjusted to reflect the terms and conditions of the lease (e.g., when the leases are not in the subsidiary’s functional currency). Lease payments included in the measurement of liabilities comprise: (i) fixed payments, less any lease incentive receivable; (ii) variable lease payments that depend on an index or a rate; (iii) residual value guarantees if it is reasonably certain that the Group will exercise that option; (iv) the exercise price of a purchase option, if the Group is it is reasonably certain to exercise that option; and (v) penalties for terminating the lease, if any. After the commencement date, the lease liability increases to reflect the accrual of interest and is reduced by the lease payments made. In addition, the carrying amount of the liability is remeasured if there is a change in the terms of the lease (changes in the lease term, in the amount of expected payments related to a residual value guarantee, in the evaluation of a purchase option or in an index or rate used to determine lease payments). Interest expense is recognized as finance cost and distributed over the years making up the lease period, so that a constant interest rate is obtained in each year on the outstanding balance of the lease liability. Short-term leases of one year or less or leases of low value assets are exempt from the application of the recognition criteria described above, with the payments associated with the lease recorded as an expense on a straight-line basis over the term of the lease. Right-of-use assets and lease liabilities are presented separately from other assets and liabilities, respectively, in the consolidated statement of financial position. f.2) Lessor When the Group acts as a lessor, it classifies at the commencement of the agreement whether the lease is an operating or finance lease, based on the substance of the transaction. Leases in which all the risks and rewards incidental to ownership of an underlying asset are substantially transferred are classified as finance leases. All other leases are classified as operating leases. For finance leases, at the commencement date, the Company recognizes in its statement of financial position the assets held under finance leases and presents them as an account receivable, for an amount equal to the net investment in the lease, calculated as the sum of the present value of the lease payments and the present value of any accrued residual value, discounted at the interest rate implicit in the lease. Subsequently, finance income is recognized over the term of the lease, based on a model that reflects a constant rate of return on the net financial investment made in the lease. For operating leases, lease payments are recognized as income on a straight-line basis, over the term of the lease unless another type of systematic basis of distribution is deemed more representative. The initial direct costs incurred in obtaining an operating lease are added to the carrying amount of the underlying asset and are recognized as expense throughout the lease period, applying the same basis as for rental income.
Financial instruments	g) Financial instruments Financial instruments are contracts that give rise to both a financial asset in one entity and a financial liability or equity instrument in another entity. g.1) Financial assets other than derivatives The Group classifies its non-derivative financial assets, whether permanent or temporary, excluding investments accounted for using the equity method (see Notes 3.i and 13) and non-current assets and disposal groups held for sale or distribution to owners (see Note 3.k), into three categories: (i) Amortized cost This category includes the financial assets that meet the following conditions (i) the business model that supports the financial assets seeks to maintain such financial assets to obtain contractual cash flows, and (ii) the contractual terms of such financial assets give rise on specific dates to cash flows that are solely payments of principal and interest (SPPI criterion). Financial assets that meet the conditions established in IFRS 9, to be valued at amortized cost in the Group are: cash equivalents, accounts receivable and, loans. Such assets are recorded at amortized cost, which is the initial fair value, less repayments of principal, plus uncollected accrued interest, calculated using the effective interest method. The effective interest method is a method for calculating the amortized cost of a financial asset or a financial liability (or a group of financial assets or financial liabilities) and allocating the finance income or financial costs throughout the relevant period. The effective interest rate is the discount rate that exactly matches the estimated cash flows to be received or paid over the expected useful life of the financial instrument (or when appropriate in a shorter period of time), with the net carrying amount of the financial asset or financial liability. (ii) Financial Assets Recorded at Fair Value through Other Comprehensive Income This category includes the financial assets that meet the following conditions: (i) they are classified in a business model, the purpose of which is to maintain the financial assets both to collect the contractual cash flows and to sell them, and (ii) the contractual conditions meet the SPPI criterion. These financial assets are recognized in the consolidated statement of financial position at fair value when this can be determined reliably. For the holdings in unlisted companies or companies with low liquidity, it is usually not possible to determine the fair value reliably, therefore, when this occurs, such holdings are valued at their acquisition cost or for a lower amount if there is evidence of their impairment. Changes in fair value, net of their tax effect, are recorded in the consolidated statement of comprehensive income: Other comprehensive income, until the disposal of these financial assets, where the accumulated amount in this section is fully allocated to profit or loss for the period except for investments in equity instruments where the accumulated balance in other comprehensive income is never reclassified to profit or loss. In the event that the fair value is lower than the acquisition cost, if there is objective evidence that the asset has suffered an impairment that cannot be considered as temporary, the difference is recorded directly in the loss for the period. (iii) Financial Assets Recorded at Fair Value through Profit or Loss This category includes the trading portfolio of the financial assets that have been allocated as such upon their initial recognition and which are managed and assessed according to the fair value criterion, and the financial assets that do not meet the conditions to be classified in the two categories indicated above. These are valued in the consolidated statement of financial position at fair value, and variations in their value are recorded directly in income when they occur. g.2) Cash and cash equivalents This item within the consolidated statement of financial position includes cash and bank balances, time deposits, and other highly liquid investments (with original maturity of less than or equal to 90 days) that are readily convertible into cash and are subject to insignificant risk of changes in value. g.3) Impairment of financial assets Following the requirements of IFRS 9, the Group applies an impairment model based on the determination of expected credit losses, based on the Group’s past history, existing market conditions, as well as forward-looking estimates at the end of each reporting period. This model is applied to financial assets measured at amortized cost or measured at fair value through other comprehensive income, except for investments in equity instruments. Expected credit loss is the difference between the contractual cash flows that are due in accordance with the contract and all the cash flows that are expected to be received (i.e. all cash shortfalls), discounted at the original effective interest rate. It is determined considering: i) the Probability of Default (PD); ii) Loss Given Default (LGD), and iii) Exposure at Default (EAD). To determine the expected credit losses the Group applies two separate approaches: • General approach: applied to financial assets other than trade accounts receivable, contractual assets or lease receivables. This approach is based on the evaluation of significant increases in the credit risk of financial assets, from the date of initial recognition. If on the reporting date of the financial statements the credit risk has not increased significantly, the impairment losses are measured related to the expected credit losses in the next 12 months; if, on the contrary, the credit risk has increased significantly, the impairment is measured considering the expected credit losses throughout the lifetime of the asset. In general, the measurement of expected credit losses for financial assets other than trade accounts receivable, contractual assets or lease receivables, are performed separately. • Simplified approach: The Group applies a simplified approach for trade receivables, contract assets and lease receivables so that the impairment provision is always recognized related to the lifetime expected credit losses for the asset. This is the approach that the Group has mostly applied because trade receivables represent the main financial asset of Enel Chile and its subsidiaries. For trade accounts receivable, contractual assets and lease receivables, the Group applies two types of evaluations of expected credit losses: - Collective evaluation: based on grouping accounts receivable into specific groups or “clusters”, taking into account each business and the local regulatory context. Accounts receivables are grouped according to the characteristics of customer portfolios in terms of credit risk, maturity information and recovery rates. A specific definition of default is considered for each group. To measure the expected credit losses collectively, the Group considers the following assumptions: - PD: average default estimate, calculated for each group of trade receivables, taking into account a minimum of 24-month historical data. - LGD: calculated based on the recovery rates of a predetermined section, discounted at the effective interest rate; and - EAD: accounting exposure at the reporting date, including invoices issued but not due and invoices pending issuance for services rendered, net of potential cash deposits obtained as guarantees. - Analytical or individual evaluation: if accounts receivables are considered individually significant by Management and there is specific information regarding any significant increase in the credit risk, the Group applies an individual evaluation of accounts receivable. For the individual evaluation, the PD is obtained mainly from an external supplier, when it is possible to do so, and the LGD through an internal model that considers the recovery rate and other contractual and financial characteristics of accounts receivable. The expected credit loss is obtained by multiplying both factors by the EAD, which is defined as the accounting exposure at the reporting date, including the invoices issued but not due and invoices pending issuance for services rendered, net of potential cash deposits obtained as guarantees. On the basis of the benchmark market and the regulatory context of the sector as well as the recovery expectations after 90 days for those accounts receivable, the Group mainly applies a predetermined definition of 180 days overdue to determine expected credit losses, since this is considered an effective indicator of a significant increase in credit risk and, accordingly, in the impairment of receivables. Based on specific evaluations performed by Management, the prospective adjustment can be applied considering qualitative and quantitative information to reflect possible future events and macroeconomic scenarios, which may affect the risk of the portfolio or the financial instrument. g.4) Financial liabilities other than derivatives General financial liabilities are initially recognized, at fair value net of any costs incurred in the transaction. In subsequent periods, these obligations are measured at their amortized cost using the effective interest method (see Note 3.g.1). Lease liabilities are initially measured at the present value of future lease payments, determined in accordance with the criteria described in Note 3.f. In the particular case that a liability is the hedged item in a fair value hedge, as an exception, such liability is measured at its fair value for the portion of the hedged risk. In order to calculate the fair value of debt, both when it is recorded in the statement of financial position and for fair value disclosure purposes as shown in Note 23, debt has been divided into fixed interest rate debt (hereinafter “fixed-rate debt”) and floating interest rate debt (hereinafter “floating-rate debt”). Fixed-rate debt is that on which fixed-interest coupons established at the beginning of the transaction are paid explicitly or implicitly over its term. Floating-rate debt is that debt issued at floating interest rate, i.e., each coupon is established at the beginning of each period based on the benchmark interest rate. All debt has been measured by discounting expected future cash flows with a market interest rate curve based on the payment currency. ​ g.5) Derivative financial instruments and hedge accounting Derivatives held by the Group are transactions entered into to hedge interest and/or exchange rate risk, intended to eliminate or significantly reduce these risks in the underlying transactions being hedged. Derivatives are recorded at fair value at the end of each reporting period as follows: if their fair value is positive, they are recorded within “Other financial assets” and if their fair value is negative, they are recorded within “Other financial liabilities”. For derivatives on commodities, positive fair value is recorded in “Trade and other receivables”, and negative fair value, if any, is recognized in “Trade and other liabilities”. Changes in fair value are recorded directly in profit or loss, except when the derivative has been designated for hedge accounting purposes as a hedging instrument and all of the conditions for applying hedge accounting established by IFRS are met, including that the hedge is highly effective. In this case, changes are recognized as follows: - Fair value hedges: The underlying portion for which the risk is being hedged and the hedging instrument are measured at fair value, and any changes in the value of both items are recognized in the statement of comprehensive income offsetting the effects in the same caption of the statement comprehensive income. - Cash flow hedges: Changes in the fair value of the effective portion of the hedged item and hedge instrument are recognized in other comprehensive income and accumulated in an equity reserve referred to as “Hedging reserve.” The cumulative loss or gain in this caption is transferred to the consolidated statement of comprehensive income to the extent that the hedged item impacts the consolidated statement of comprehensive income offsetting the effect in the same comprehensive income statement caption. Gains or losses from the ineffective portion of the hedging relationship are recognized directly in the statement of comprehensive income. Hedge accounting is discontinued only when the hedging relationship (or a part of the relationship) fails to meet the required criteria, after making any rebalancing of the hedging relationship, if applicable. If it is not possible to continue the hedging relationship, including when the hedging instrument expires, is sold, settled or exercised, any gain or loss accumulated in equity at that date remains in the equity until the forecast transaction affects the statement of comprehensive income. When a forecast transaction is no longer expected to occur, the gain or loss accumulated in equity is immediately transferred to the statement of income. As a general rule, long-term commodity purchases or sales agreements are recognized in the statement of financial position at their fair value at the end of each reporting period, recognizing any differences in value directly in profit or loss, except for, when all of the following conditions are met: - The sole purpose of the agreement is for its own use, which is understood as: for fuel purchase agreements such use is to generate electricity; for electrical energy purchased for sale, its sale is to the end-customers; and for electricity sales its sale is to the end-customers. - The Group’s future projections evidence the existence of these agreements for own use. - Past experience with agreements shows that they have been use for the Group’s “own use”, except for certain isolated cases when for exceptional reasons or reasons associated with logistical issues, these have been used for other purposes beyond the Group’s control and expectations. - The agreement does not establish net settlement of differences and there has been no practice to settle similar differences in similar contracts in the past. The long-term commodity purchase or sale agreements maintained by the Group, which are mainly for electricity, fuel, and other supplies, meet the conditions described above. Accordingly, the purpose of fuel purchase agreements is to use them to generate electricity, electricity purchase contracts for use in sales to end-customers, and electricity sale contracts for sale of the Group’s own products. The Group also evaluates the existence of derivatives embedded in contracts or financial instruments to determine if their characteristics and risk are closely related to the host contract, provided that when taken as a whole they are not being accounted for at fair value. If they are not closely related, they are recorded separately and changes in value are accounted for directly in the statement of comprehensive income. g.6) Derecognition of financial assets and liabilities Financial assets are derecognized when: - The contractual rights to receive cash flows from the financial asset expire or have been transferred or, even when, the Group has assumed a contractual obligation to pay these cash flows to one or more recipients. - The Group has substantially transferred all the risks and rewards of their ownership, or, if it has neither assigned nor retained substantially all the risks and rewards, when it does not retain control of the financial asset. For transactions in which the Group retains substantially all the inherent risks and rewards of their ownership of the financial asset assigned, it recognizes them as a financial liability for the consideration received. Transactions costs are recognized in profit and loss by using the effective interest method (see Note 3.g.1). Financial liabilities are derecognized when they are extinguished; i.e., when the obligation arising from the liability has been paid or cancelled or has expired. An exchange for a debt instrument with substantially different conditions, or a substantial modification in the current conditions of an existing financial liability (or a part thereof), is recorded as a cancellation of the original financial liability, and a new financial liability is recognized. g.7) Offsetting of financial assets and financial liabilities The Group offsets financial assets and liabilities and the net amount is presented in the statement of financial position only when: - there is a legally binding right to offset the amounts recognized; and - the Group intends to settle them on a net basis, or to realize the asset and settle the liability simultaneously. Such rights may only be legally enforceable in the normal course of business, or in the event of default, or in the event of insolvency or bankruptcy, of one or all the counterparties. g.8) Financial guarantee contracts The financial guarantee contracts, defined as the guarantees issued by the Group to third parties, are initially measured at their fair value, adjusted for transaction costs that are directly attributable to the issuance of the guarantee. Subsequent to initial recognition, financial guarantee contracts are recognized at the higher of: - the amount of the liability determined in accordance with the accounting policy described in Note 3.m; and - the amount of the asset initially recognized less, if applicable, any accumulated amortization recognized in accordance with the revenue recognition policies described in Note 3.q.
Fair value measurement	h) Fair value measurement The fair value of an asset or liability is defined as the price that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurement assumes that the transaction to sell an asset or transfer a liability occurs in the principal market, namely, the market with the greatest volume and level of activity for that asset or liability. In the absence of a principal market, it is assumed that the transaction is carried out in the most advantageous market available to the entity, namely, the market that maximizes the amount that would be received to sell the asset or minimizes the amount that would be paid to transfer the liability. In estimating fair value, the Group uses valuation techniques that are appropriate for the circumstances and for which there is sufficient data to perform the measurement where it maximizes the use of relevant observable data and minimizes the use of unobservable data. Given the hierarchy explained below, data used in the valuation techniques, assets and liabilities measured at fair value can be classified at the following levels: • Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities • Level 2: Inputs other than quoted prices included in Level 1 that are observable for the assets or liabilities, either directly (i.e. as prices) or indirectly (i.e. derived from prices). The methods and assumptions used to determine the fair values at Level 2 by type of financial assets or financial liabilities take into consideration estimated future cash flows discounted at market rates. Future cash flows for financial assets and financial liabilities are discounted with the zero-coupon interest rate curves for each currency. These valuations are performed using external tools such as Bloomberg. • Level 3: Inputs for assets or liabilities that are not based on observable market data (unobservable inputs). The Group takes into account the characteristics of the asset or liability when measuring fair value, in particular: - For non-financial assets, fair value measurement takes into account the ability of a market participant to generate economic benefits by using the asset in its highest and best use or by selling it to another market participant that would use the asset at its highest and best use; - For liabilities and equity instruments, the fair value measurement assumes that the liability would not be settled, and an equity instrument would not be cancelled or otherwise extinguished on the measurement date. The fair value of the liability reflects the effect of non-performance risk, namely, the risk that an entity will not fulfill the obligation, which includes but is not limited to, the Company’s own credit risk; - For derivatives not traded in active markets, the fair value is determined by using the discounted cash flow method and generally accepted options valuation models, based on current and future market conditions as of the closing date of the financial statements. This methodology also adjusts the value based on the Company’s own credit risk (Debt Valuation Adjustment, DVA), and the counterparty risk (Credit Valuation Adjustment, CVA). These CVA and DVA adjustments are measured on the basis of the potential future exposure of the instrument (asset or liability position) and the risk profile of both the counterparties and the Group itself.   - For financial assets and financial liabilities with offsetting positions in market risks or counterparty credit risks, measuring the fair value on a net basis is allowed. However, this must be consistent with the manner in which market participants would price the net risk exposure at the measurement date. Financial assets and financial liabilities measured at fair value are shown in Note 23.3. ​
Investments accounted for using the equity method	i) Investments accounted for using the equity method The Group’s interests in joint ventures and associates are recognized using the equity method of accounting (see Notes 2.5 and 2.6 respectively). Under the equity method of accounting, an investment in an associate or joint venture is initially recognized at cost. As of the acquisition date, the investment is recognized in the statement of financial position based on the share of equity that the Group’s interest represents in capital, adjusted for, if appropriate, the effect of transactions with the Group plus any goodwill generated in acquiring the company. If the resulting amount is negative, zero is recorded for that investment in the statement of financial position, unless the Group has a present obligation (either legal or constructive) to reinstate the Company’s equity position, in which case a provision is recognized. The financial statements of associates or joint ventures are prepared for the same reporting period as the Group. When necessary, adjustments are made to align the accounting policies with those of the Group. Goodwill from the associate or joint venture is included in the carrying amount of the investment. It is not amortized but is subject to impairment testing as part of the overall investment carrying amount when there are indicators of impairment. Dividends received from these investments are deducted from the carrying amount of the investment, and any profit or loss obtained from them to which the Group is entitled based on its ownership interest is recognized under “Share of profit (loss) of associates accounted for using the equity method of accounting”.
Inventories	j) Inventories Inventories are measured at their weighted average acquisition cost or the net realizable value, whichever is lower. The net realizable value is the estimated selling price in the ordinary course of business less the applicable costs to sell.
Non-current assets (or disposal groups of assets) held for sale or held for distribution to owners and discontinued operations.	k) Non-current assets (or disposal groups of assets) held for sale or held for distribution to owners and discontinued operations. Non-current assets, including property, plant and equipment; intangible assets; investments accounted for using the equity method of accounting and joint ventures and disposal groups (a group of assets for disposal or distribution together with liabilities directly associated with those assets), are classified as: - Held for sale, if their carrying amount will be recovered mainly through a sale transaction rather than through continuing use, or - Held for distribution to owners, when the entity is committed to distribute the assets (or disposal groups) to the owners. For the above classifications, the assets must be available for immediate sale or distribution in their present condition and their sale or distribution must be highly probable. For a transaction to be considered highly probable, management must be committed to the sale or distribution and actions to complete the transaction must have been initiated and should be expected to be completed within one year from the date of classification. Actions required to complete the sale or distribution plan should indicate that it is unlikely that significant changes to the plan can be made or that the plan will be cancelled. The probability of shareholders’ approval (if required in the jurisdiction) should be considered as part of the assessment of whether the sale or distribution is highly probable. The assets or disposal groups classified as held-for-sale or held for distribution to owners are measured at the lower of their carrying amount and fair value less costs to sell or costs to distribute, as appropriate. Depreciation and amortization on these assets cease when they meet the criteria to be classified as non-current assets held for sale or held for distribution to owners. Assets that are no longer classified as held for sale or held for distribution to owners, or are no longer part of a disposal group, are measured at the lower of their carrying amounts before being classified as held for sale or held for distribution, less any depreciation, amortization or revaluation that would have been recognized had they had not been classified as held for sale or held for distribution to owners and their recoverable amount at the date of reclassification as non-current assets. Non-current assets held for sale and the components of the disposal groups classified as held for sale or held for distribution to owners are presented in the consolidated statement of financial position as a single line item within assets referred to as “Non-current assets or disposal groups held for sale or for distribution to owners”, and the related liabilities are presented as a single line item within liabilities referred to as “Liabilities included in disposal groups held for sale or for distribution to owners”. The Group classifies as discontinued operations those components of the Group that either have been disposed of, or are classified as held for sale and: - represent a separate major line of business or geographical area of operations; - is part of a single coordinated plan to dispose of a separate major line of business or geographical area of operations; or - is a subsidiary acquired exclusively with a view to resale it. The after-tax results of discontinued operations are presented in a single line of the statement of comprehensive income referred to as “Profit (loss) from discontinued operations”, as well as the gain or loss recognized from the measurement at fair value less costs to sell or from the disposal of the assets or groups for disposal comprising the discontinued operation.
Treasury shares	l) Treasury shares Treasury shares are presented deducting the caption “Total equity” in the consolidated statement of financial position and measured at acquisition cost. Gains and losses from the disposal of treasury shares are recognized directly in “Total Equity – Retained earnings (losses)”, without affecting profit or loss for the period.
Provisions	m) Provisions Provisions are recognized when the Group has a present obligation (legal or constructive) as a result of a past event, it is probable that an outflow of economic benefits will be required to settle the obligation, and a reliable estimate can be made of the amount of the obligation. The amount recognized as a provision is the best estimate of the consideration required to settle the present obligation at the end of the reporting period, taking into account the risks and uncertainties surrounding the obligation. When a provision is measured using the cash flows estimated to settle the present obligation, its carrying amount is the present value of those cash flows (when the effect of the time value of money is material). The unwinding of the discount is recognized as finance cost. Incremental legal costs expected to be incurred in resolving a legal claim are included in measuring of the provision. Provisions are reviewed at the end of each reporting period and adjusted to reflect the current best estimate. If it is no longer probable that an outflow of resources embodying economic benefits will be required to settle the obligation, the provision is reversed. A contingent liability does not result in the recognition of a provision. Legal costs expected to be incurred in defending a legal claim are expensed as incurred. Significant contingent liabilities are disclosed unless the likelihood of an outflow of resources embodying economic benefits is remote. m.1) Provisions for post-employment benefits and similar obligations Certain of the Group’s companies have entered into pension and other similar commitments with their employees. Those defined benefit and defined contribution commitments are basically through pension plans, except for those related to certain benefits in lieu of payment, basically commitments to supply electric energy, which, due to their nature have not been outsourced and their coverage is provided through the related internal provision. For defined benefit plans, the companies record the related expense for these commitments following the accrual criteria over the service life of the employees through timely actuarial studies performed as of the reporting date calculated applying the projected credit unit method. The cost of past services which correspond to variances in benefits is recognized immediately. The defined benefit plan obligations in the statement of financial position represent the present value of the accrued obligations, upon deduction of the fair value of the different plans’ assets, if any. Actuarial gains and losses arising from measurements of both the plan liabilities and the plan asset, are recorded directly as a component of “Other comprehensive income”.
Translation of balances in foreign currency	n) Translation of balances in foreign currency Transactions performed by each entity in a currency other than its functional currency are recognized using the exchange rates prevailing as of the date of the transactions. During the period, differences arising between the prevailing exchange rate at the date of the transaction and the exchange rate as of the date of collection or payment are recognized as “Foreign currency translation differences” in the consolidated statement of comprehensive income. Likewise, at the end of each reporting period, balances receivable or payable denominated in a currency other than each entity’s functional currency are remeasured using the closing date exchange rate. Any differences are recorded as “Foreign currency translation differences” in the consolidated statement of comprehensive income. The Group has established a policy to hedge the portion of revenue from its consolidated entities that is directly linked to variations in the U.S. dollar, through obtaining financing in such currency. Exchange differences related to this debt, which is regarded as the hedging instrument in cash flow hedge transactions, are recognized, net of taxes, in other comprehensive income and are accumulated in an equity reserve and recorded in profit or loss in the term in which the cash flows hedged will be realized. This term has been estimated as ten years.
Classification of balances as current and non-current	o) Classification of balances as current and non-current In these consolidated statements of financial position, assets and liabilities expected to be recovered or settled within twelve months are presented as current assets or liabilities, except for post-employment and other similar obligations. Those assets and liabilities expected to be recovered or settled in more than twelve months are presented as non-current items. Deferred income tax assets and liabilities are classified as non-current. When the Group has any obligations that mature in less than twelve months but can be refinanced over the long term at the Group’s discretion, through unconditionally available loan agreements with long-term maturities, such obligations are classified as non-current liabilities.
Income taxes	p) Income taxes Income tax expense for the period is determined as the sum of current taxes from each of the Group’s subsidiaries and results from applying the tax rate to the taxable income for the period, after deductions allowed have been made, plus any changes in deferred tax assets and liabilities and tax credits, both for tax losses and deductions. Differences between the carrying amount and tax basis of assets and liabilities generate deferred tax assets and liabilities, which are calculated using the tax rates expected to be applied when the assets and liabilities are realized or settled, based on tax rates that have been enacted or substantively enacted by the end of the reporting period. Deferred tax assets are recognized for all deductible temporary differences, tax losses and unused tax credits to the extent that it is probable that sufficient future taxable profits exist to recover the deductible temporary differences and use the tax credits. Such deferred tax asset is not recognized if the deductible temporary difference arises from the initial recognition of an asset or liability that: - did not arise from a business combination; and - at initial recognition provide it affected neither accounting profit nor taxable profit (loss). With respect to deductible temporary differences associated with investments in subsidiaries, associates and joint arrangements, deferred tax assets are recognized only to the extent that it is probable that the temporary differences will reverse in the foreseeable future and taxable profits will be available against which the temporary differences can be utilized. Deferred tax liabilities are recognized for all temporary differences, except for those derived from the initial recognition of goodwill and those that arose from investments in subsidiaries, associates and joint ventures in which the Group can control their reversal and where it is probable that they will not be reversed in the foreseeable future. Current tax and changes in deferred tax assets or liabilities are recorded in profit or loss, other comprehensive income or total equity in the statement of financial position, depending on where the gains or losses that triggered these tax entries have been recognized. Any tax deductions that can be applied to current tax liabilities are credited to earnings within the line item “Income tax expenses”, except when uncertainty exists about their tax realization, in which case they are not recognized until they are effectively realized, or when they relate to specific tax incentives, in which case they are recorded as grants. At the end of each reporting period, the Group reviews the deferred tax assets and liabilities recognized, and makes, any necessary corrections based on the results of this analysis. Deferred tax assets and deferred tax liabilities are offset in the consolidated statement of financial position if the Group has a legally enforceable right to set off current tax assets against current tax liabilities, and only when the deferred taxes relate to income taxes levied by the same tax authority.
Revenue and expense recognition	q) Revenue and expense recognition Revenue is recognized when (or as) the control over a good or service is transferred to the customer. Revenue is measured based on the consideration to which the Group is expected to be entitled for said transfer of control, excluding the amounts collected on behalf of third parties. The Group analyzes and takes into consideration all the relevant facts and circumstances for revenue recognition, applying the five-step model established by IFRS 15: 1) Identifying the contract with a customer; 2) Identifying the performance obligations; 3) Determining the transaction price; 4) Allocating the transaction price; and 5) Recognizing revenue. The following are the criteria for revenue recognition by type of good or service provided by the Group: • Electricity supply (sale and transportation): corresponds to a single performance obligation that transfers to the customer a number of different goods/services that are substantially the same and that have the same transfer pattern. Since the customer receives and simultaneously consumes the benefits provided by the Company, it is considered a performance obligation met over time. In these cases, the Group applies an output method to recognize revenue in the amount to which it is entitled to bill for electricity supplied to date. - Generation: revenue is recorded according to the physical deliveries of energy and power, at the prices established in the respective contracts, at the prices established in the electricity market by the current regulations, or at the marginal cost of energy and power, depending on whether they are unregulated customers, regulated customers or energy trading in the spot market are involved, respectively. - Distribution of electricity: revenue is recognized based on the amount of energy supplied to customers during the period, at prices established in the related contracts or at prices stipulated in the electricity market by applicable regulations, as appropriate. These revenues include an estimate of the service provided and not invoiced, through the reporting date of the financial statements (see Notes 2.3 and 28 and Appendix 2.2). • Gas sale and transport: revenue is recognized over time based on the actual physical deliveries of gas in the consumption period, at the prices established in the respective contracts. • Other Services: mainly the provision of supplementary services to the electricity business, construction of works and engineering and consulting services. Customers control committed assets as they are created or improved. Therefore, the Company recognizes this revenue over time based on the progress, measuring progress through output methods (percentage of completion through the present date, milestones reached, etc.), or costs incurred (resources consumed, hours of labor spent, etc.), as appropriate in each case. • Sale of goods: revenue from the sale of goods is recognized at a certain time, when control of the goods has been transferred to the customer, which generally occurs at the time of the physical delivery. Revenues are measured at the independent sale price of each good, and any type of applicable variable compensation. In contracts in which multiple committed goods and services are identified, the recognition criteria will be applied to each of the identifiable performance obligations of the transaction, based on the control transfer pattern of each good or service that is separate and an independent selling price allocated to each of them, or jointly to two or more transactions, when these are linked to contracts with customers that are negotiated with a single business purpose and the goods and services committed represent a single performance obligation and their selling prices are not independent. The Group determines the existence of significant financing components in its contracts, adjusting the value of the consideration if applicable, to reflect the effects of the time value of money. However, the Group applies the practical expedient provided by IFRS 15, and will not adjust the value of the consideration committed for the purpose of a significant financing component, if it expects, at the beginning of the contract, that the period between the payment and the transfer of goods or service to the customer is one year or less. The Group excludes the gross revenue of economic benefits received when acting as an agent or broker on behalf of third parties from the revenue amount. The Group only records as revenue the payment or commission to which it expects to be entitled. Because the Group mainly recognizes revenue for the amount to which it has the right to invoice, it has decided to apply the disclosure practical expedient provided in IFRS 15, through which it is not required to disclose the aggregate amount of the transaction price allocated to the performance obligations not met (or not met partially) at the end of the reporting period. In addition, the Group evaluates the existence of incremental costs of obtaining a contract and costs directly related to the fulfillment of a contract. These costs are recognized as an asset, if their recovery is expected, and amortized in a manner consistent with the transfer of the related goods or services. As a practical expedient, the incremental costs of obtaining a contract are recognized as an expense, if the depreciation period of the asset that has been recognized is one year or less. Costs that do not qualify for capitalization are recognized as expenses at the time they are incurred, unless they are explicitly attributable to the customer. As of December 31, 2022, and 2021, the Group has not incurred costs to obtain or perform a contract which meet the conditions for their capitalization. The costs incurred to obtain a contract are substantially commission payments for sales that, although are incremental costs, relate to short-term contracts or performance obligations that are met at a certain time, therefore, the Group has decided to recognize these costs as an expense when they occur. Interest income (expense) are recorded considering the effective interest rate applicable to the principal pending amortization during the related accrual period.
Earnings per share	r) Earnings per share Basic earnings per share are calculated by dividing net income attributable to shareholders of the Parent Company by the weighted average number of ordinary shares of outstanding during the period, excluding the average number of shares of the Company held by other subsidiaries within the Group, if any. Basic earnings per share for continuing and discontinued operations are calculated by dividing net income from continuing and discontinued operations attributable to shareholders of the Company (the numerator) by the weighted average number of shares of common stock outstanding (the denominator) during the year, excluding the average number of shares of the Company held by other subsidiaries within the Group. Diluted earnings per share is calculated by dividing profit attributable to shareholders of the Parent Company by the weighted average number of ordinary shares outstanding during the period plus the weighted average number of ordinary shares of that would be issued on conversion of all the potential dilutive securities into ordinary shares, if any.
Dividends	s) Dividends Article No. 79 of Law No. 18,046 (Chilean Corporations Law) establishes that, unless unanimously agreed otherwise by the shareholders of all issued shares, listed corporations must distribute a cash dividend to shareholders on an annual basis, pro rata among the shares owned or the proportion established in the Company’s by-laws if there are preferred shares, of at least 30% of profit for each year, except when accumulated losses from prior years must be absorbed. As it is practically impossible to achieve a unanimous agreement given Enel Chile highly fragmented share ownership, at the end of each reporting period the amount of the minimum statutory dividend obligation to its shareholders is determined, net of interim dividends approved during the period, and then accounted for in “Trade and other payables, current” and “Current accounts payable to related parties”, as appropriate, and recognized in equity. The interim and final dividends are deducted from equity when approved by the relevant authority, which in the first case is normally the Board of Directors and in the second case is the responsibility of the shareholders as agreed at a General Shareholders’ Meeting.
Share issuance costs	t) Share issuance costs Share issuance costs, only when they represent incremental expenses directly attributable to the transaction, are recognized directly in equity as a deduction from “Share premiums,” net of any applicable taxes. If the share premium account has a zero balance or if the costs described exceed the balance, they are recognized in “Other reserves”. Subsequently, these costs must be deducted from paid-in capital, and this deduction must be approved at the closest Extraordinary Shareholders’ Meeting, which occurs immediately after the date on which the disbursements were incurred. Share issuance and placement expenses directly related to a probable future transaction are recorded as prepaid expenses in the statement of financial position. These expenses are recorded in equity upon issuance and placement of the shares, or in profit or loss when the conditions change and the transaction is no longer expected to occur.
Statement of cash flows	u) Statement of cash flows The statement of cash flows reflects changes in cash and cash equivalents that took place during the period, determined with the direct method. It uses the following definitions and related meanings: - Cash flows: inflows and outflows of cash or cash equivalents, which are defined as highly liquid investments maturing in less than three months with a low risk of changes in value. - Operating activities: the principal revenue-producing activities of the Group that cannot be considered investing or financing activities. - Investing activities: the acquisition and disposal of long-term assets and other investments not included in cash and cash equivalents. - Financing activities: activities that result in changes in the size and composition of the total equity and borrowings of the Group.
