Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors

Enel Generación Chile S.A.:

We have audited the accompanying consolidated statements of financial position of Enel Generación Chile S.A. and subsidiaries (the Company) as of December 31, 2017 and 2016, the related consolidated statements of comprehensive income, changes in equity, and cash flows for each of the years in the three year period ended December 31, 2017, and the related notes (collectively, the consolidated financial statements). In our opinion, based on our audits and the reports of the other auditors, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the years in the three year period ended December 31, 2017, in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated April 26, 2018, expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

We did not audit the financial statements of Emgesa S.A. E.S.P. and its subsidiaries and Endesa Argentina S.A. and its subsidiaries, which statements reflect ThCh$321,253,877 of the Company’s consolidated profit from discontinued operations for the year ended December 31, 2015. In addition, we did not audit the financial statements of Enel Brasil S.A. (38.64 percent owner investee company as of December 31, 2015). The Company’s equity in earnings in Enel Brasil S.A. for the year ended December 31, 2015 was ThCh$36,473,505. Those consolidated financial statements prepared in accordance with the local statutory accounting basis were audited by other auditors whose reports have been furnished to us and our opinion, insofar as it relates to the amounts included for those entities on such basis of accounting, is based solely on the reports of the other auditors. Accordingly, we have audited the conversion adjustments to the financial statements of these subsidiaries and nonsubsidiary investees prepared in accordance with the local statutory accounting basis to conform them to the Company’s accounting basis referred to above.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

 

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Company’s auditor since 2008.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors

Enel Generación Chile S.A.:

Opinion on Internal Control Over Financial Reporting

We have audited Enel Generación Chile S.A. and subsidiaries (the Company) internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated statements of financial position of the Company as of December 31, 2017 and 2016, the related consolidated statements of  comprehensive income, changes in equity, and cash flows for each of the years in the three year period ended December 31, 2017, and the related notes (collectively, the consolidated financial statements), and our report dated April 26, 2018 expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion.

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

ENEL GENERACIÓN CHILE S.A. AND ITS SUBSIDIARIES

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(In thousands of Chilean pesos – ThCh$)

1. THE GROUP’S ACTIVITIES AND FINANCIAL STATEMENTS

Enel Generación Chile S.A (hereinafter the “Parent Company” or the “Company”) and its subsidiaries comprise the Enel Generación Chile Group (hereinafter the Enel Generación Chile or the “Group”).

Enel Generación Chile S.A. is a publicly traded corporation with a registered address and head office located at Avenida Santa Rosa, No. 76, in Santiago, Chile. The Company is registered in the securities register of  the Finantial Market Commission of Chile (“Comisión para el Mercado Financiero” or “CMF”, formerly Chilean Superintendence of Securities and Insurance, “Superintendencia de Valores y Seguros” or “SVS”) under number 114. In addition, the Company is registered with the Securities and Exchange Commission of the United States of America (hereinafter U.S. SEC). The Company’s shares have been listed on the New York Stock Exchange since 1994.

Enel Generación Chile S.A. is a subsidiary of Enel Chile S.A. (”Enel Chile”) a company which, in turn, is a subsidiary Enel S.p.A. (hereinafter “Enel”).

The Company was initially incorporated by a public deed dated December 1, 1943 under the name Empresa Nacional de Electricidad S.A. The Treasury Department’s Supreme Decree No. 97 of January 3, 1944 authorized the incorporation of the Company and approved its by-laws. The Company changed its name to Enel Generación Chile S.A. effective October 4, 2016, the date its by-laws were amended in connection with the corporate reorganization of the Group (see Note 5.3). For tax purposes, the Company operates under Chilean tax identification number 91.081.000-6.

As of December 31, 2017 the Group had 848 employees. During the year ended December 31, 2017, the Group averaged a total of 867 employees (see Note 34).

The Group’s corporate purpose consists of generating, transporting, producing, and distributing electrical energy. The Company’s corporate purpose also includes investing in financial assets, developing projects, carrying out activities in the energy industry and in other fields in which electrical energy is essential, and participating in public civil or hydraulic infrastructure concessions in which it may participate directly or through subsidiaries or associate companies in Chile or abroad.

1.1 Enel Group Proposed Corporate Reorganization

Enel Generación Chile’s Board of Directors at its Extraordinary Session held on September 1, 2017, unanimously resolved to initiate all work and steps necessary to analize the corporate reorganization proposed by our parent Enel Chile, in the terms applicable to Enel Generación Chile.

Enel Chile’s proposal consists of a corporate reorganization within Enel, which is intended to incorporate the renewable energy assets in Chile held through Enel Green Power Latin America S.A. (“EGPL”) with Enel Chile. EGPL is a subsidiary of Enel, actually controlled by Enel Green Power SpA..

The proposal also implies that the merger is contingent on the success of a Public Tender Offer (“Tender Offer”) to be carried out by Enel Chile for all of the shares of its subsidiary Enel Generación Chile held by non-controlling interests

The Reorganization is expected to involve two principal phases, each of which is conditional on the implementation of the other, as follows:

F-14

(i) Public tender offer

Enel Chile will launch a public tender offer (the “Tender Offer”) for all of the shares of its subsidiary Enel Generación Chile S.A. (“Enel Generación Chile”) held by non-controlling interests (equivalent to approximately 40% of the share capital). The Tender Offer consideration is expected to be paid in cash, subject to the condition that tendering Enel Generación Chile shareholders will have agreed to use a specified portion of the cash consideration to subscribe for shares or American Depositary Shares (“ADSs”) of Enel Chile (the “Share/ADS Subscription Condition”).

The effectiveness of the Tender Offer will be conditional on satisfaction or waiver of the following:

- The tender in the Tender Offer of a total number of shares that would enable Enel Chile to increase its ownership interest in Enel Generación Chile to more than 75% from the current 60%;

- The approval by Enel Generación Chile’s shareholders’ meeting of an amendment to the company’s bylaws to provide that Enel Generación Chile is no longer be subject to (i) Title XII of Decree No. 3,500 of 1980 (the Chilean law that regulates pension fund investments) or (ii) the existing limits to share ownership in the company, which currently do not allow any single shareholder to own more than 65% of the company’s share capital;

- Enel Chile has available for issuance in the Tender Offer the necessary number of newly issued Enel Chile Shares following the expiration of the preemptive right period in the related capital increase to permit the subscription of the number of shares and ADSs of Enel Chile required to satisfy the Share/ADS Subscription Condition;

- The absence of any legal proceeding or action seeking to (i) prohibit or prevent the Merger between Enel Chile and EGPL; (ii) impose material limitations on Enel Chile’s ability to effectively exercise its property rights over the assets of EGPL to be assigned to Enel Chile as a consequence of the Merger; (iii) impose limitations on Enel Chile’s ability to continue developing and operating the projects owned by EGPL; and (iv) in general, any legal proceeding or action before any regulatory, judicial or administrative authority resulting in any of the consequences indicated in (i) to (iii) above;

- The absence of any legal proceeding or action seeking to (i) prohibit or prevent the closing of the Tender Offer; (ii) impose material limitations on Enel Chile’s ability to effectively acquire the Enel Generación Chile shares and Enel Generación Chile ADSs; (iii) impose limitations on Enel Chile’s ability to exercise its property rights over the Enel Generación Chile shares and Enel Generación Chile ADSs validly tendered and not validly withdrawn pursuant to the Tender Offer; and (iv) in general, any legal proceeding or action before any regulatory, judicial or administrative authority resulting in any of the consequences indicated in (i) to (iii) above;

- The Share/ADS Subscription Condition;

- Enel S.p.A must maintain at all times an ownership interest in Enel Chile of more than 50% and maintain its controlling shareholder position and shall not exceed the 65% stock ownership limit set forth in Enel Chile’s bylaws after the consummation of the proposed Reorganization;

- All of the other conditions to the Merger (other than the consummation of the Tender Offer); and

- The absence of any material adverse effect.

(ii) Merger

Following the completion of the Tender Offer, EGPL will merge into Enel Chile (the “Merger”). Consequently, the renewable assets held by EGPL will be integrated into Enel Chile.

Subject to the final share subscription price in the Tender Offer and the exchange ratio in the Merger, Enel is expected to hold, in the aggregate, an ownership interest in Enel Chile similar to its current 60.6% ownership.

On December 20, 2017, the Extraordinary Shareholder's Meeting of Enel Generación Chile, for fulfilling one of the conditions of success of the OPA, approved the amendment of the company's bylaws to eliminate the limitations and restrictions

F-15

established in Section XII of Decree No. 3.500. The Board approved that the aforementioned amendment of the bylaws will be subject to the condition precedent that Enel Chile declares the TOB successful.

The Merger was completed on April 2, 2018. (See note 38).

2. BASIS OF PRESENTATION OF THE CONSOLIDATED FINANCIAL STATEMENTS

2.1 Accounting principles

The consolidated financial statements as of December 31, 2017 of the Group, approved for issuance by the Company’s Board of Directors at its meeting held on April 24, 2018, have been prepared in accordance with the 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 Generación Chile and its subsidiaries at December 31, 2017 and 2016, and the results of its operations, changes in equity and cash flows for the year ended December 31, 2017, 2016 and 2015.

These consolidated financial statements have been prepared under going concern assumptions on a historical cost basis except, in accordance with IFRS, those assets and liabilities that are measured at a fair value (see Note 3.f) and those non-current assets and disposal groups held for sale, which are recognized at the carrying amount or the fair value less cost of disposal, whichever is lower (see Note 3.g and 3.j).

These consolidated financial statements are presented in thousands of Chilean pesos (unless expressly stated otherwise), as the Chilean peso is the functional currency of the Company and the presentation currency of the Group. Foreign operations are incorporated in accordance with the accounting policies stated in Notes 2.7 and 3.m.

IFRIC 23: Uncertainty over Income Tax Treatments	Annual periods beginning on or after January 1, 2019

IFRS 9 Financial Instruments

In July 2014, the IASB issued the final version of IFRS 9 that replaces IAS 39 Financial Instruments: Recognition and Measurement and all previous versions of the new standard. IFRS 9 is effective for annual periods beginning on or after January 1, 2018, with early application permitted. The company will adopt the standard on the date of effective application without restating previous periods, recognizing the cumulative effect of its initial application as an adjustment to the opening balance of accumulated earnings (or another component of the estate, as appropriate).

IFRS 9 brings together all three phases of the IASB’s project on financial instruments: (i) classification and measurement, (ii) impairment and (iii) hedge accounting.

Enel Generación Chile carried out a detailed evaluation of the three aspects of the standard and its impact on the Group's consolidated financial statements. This evaluation is based on the information currently available and, therefore, may be subject to changes arising from additional information available during the year 2018.  

i) Classification and measurement.

IFRS 9 introduces a new classification approach for financial assets, based on two concepts: the characteristics of the contractual cash flows of the financial assets and the business model of the entity. Under this new approach, the four classification categories of IAS 39 are replaced by the following three categories:

- amortized cost; if the financial assets are held within a business model whose objective is to collect contractual cash flows;

- fair value through other comprehensive income, if the financial assets are held within a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets; or

- fair value through profit or loss, a residual category which consists of financial instruments that are not held within any of the two business models previously discussed, including those held for trading and those designatet at fair value on initial recognition.

For financial liabilities, IFRS 9 retains largely the existing requirements in IAS 39, with certain specific modifications, under which most of the financial liabilities are measured at amortized cost, and allowing to designate a financial liability to be measure at fair value through profit or loss, if certain criteria are met.

However, IFRS 9 introduces new requirements for financial liabilities designated at fair value through profit or loss, which states that under certain circumstances, changes in fair value originated by the variation of an entity’s own credit risk will be recognized in other comprehensive income.

Based on the assessment made, the Group considers that the new classification requirements will not have a significant impact on the accounting of its financial assets. Loans and receivables are maintained to obtain contractual cash flows representing solely payment of the principal and interest, so they meet the criteria to be measured at amortized cost under IFRS 9. Investments in equity instruments classified as available for sale will continue to be measured at fair value through profit or loss.

F-17

ii) Impairment.

The new impairment model in IFRS 9 is based on expected credit losses, as opposed to the incurred loss model in IAS 39. Consequently, under IFRS 9 impairment losses will be recognized, as a general rule, earlier than current practice.

The new impairment model will be applied to financial assets measured at amortized cost and those measured at fair value through other comprehensive income, except for investments in equity instruments. Under IFRS 9, the allowance for impairment losseswill be measured based on:

- 12 months expected credit losses; or

- Lifetime expected credit losses if the credit risk of a financial asset at the reporting date has increased significantly since initial recognition.

The standard allows the application of a simplified approach for trade receivables, contract assets and lease receivables so that the impairment is always recognized in reference to the lifetime expected credit losses for the asset. The Group has chosen to apply this policy for the designated financial assets.

Based on the new methodology for estimating expected credit losses, the Group has determined that the application of the impairment requirements of IFRS 9 as of January 1, 2018, will not have a significant impact on the consolidated financial statements of Enel Generation Chile and subsidiaries.

iii) Hedge accounting.

IFRS 9 introduces a new model for hedge accounting in order to more closely align the accounting treatment with risk management activities of the entities and to establish a new principle-based approach. The new model will enable entities to better reflect risk management activities in the financial statements, and allow more items to be eligible as hedged items, such as: non-financial risk component, net positions, and aggregated exposures (i.e., a combination of derivative and non-derivative exposure).

The most significant changes in relation to hedging instruments compared to hedge accounting methodology in IAS 39, is the possibility to defer in other comprehensive income the time value of options, forward points in forward contracts, and foreign currency basis spread, until the hedged item impacts profit or loss.

IFRS 9 eliminates the current quantitative requirement for hedge effectiveness test, under which the results must be within a range of 80-125 percent. This will allow aligning hedge effectiveness with risk management by demonstrating the existence of an economic relationship between the hedging instrument and the hedged item, and enables the rebalancing of hedging relationship if the risk management objective remains unchanged. However, retrospective ineffectiveness should continue to be valued and recognized in profit or loss.

When initially applying IFRS 9, the Group may choose as its accounting policy to continue to apply the hedge accounting requirements of IAS 39 instead of the requirements in IFRS 9, until the time the new requirements on macro-hedging are published and adopted. The Group has chosen to apply the new requirements of IFRS 9 on the date of its adoption.

Implementing the new model included assessing the existing hedge relationships and the analysis of new strategies that may be applied under the new standard. The Group considers that all the existing hedge relationships at December 31, 2017, which have been designed as efficient hedges, will continue to be suitable for hedge accounting under IFRS 9. Similarly, non-accounting hedges will continue to be measured at fair value through profit or loss under the new standard.

F-18

IFRS 15 Revenue from Contracts with Customers

In May 2014, the IASB published IFRS 15 which is applicable to all contracts with customers, with certain exemptions.the new revenue standard supersedes all current revenue recognition standards:

- IAS 11 Construction Contracts;

- IAS 18 Revenue;

- IFRIC 13 Customer Loyalty Programs;

- IFRIC 15 Agreements for the Construction of Real Estate;

- IFRIC 18 Transfers of Assets from Customers; and

- SIC-31 Revenue—Barter Transactions Involving Advertising Services.

The standard shall be applied for annual periods beginning on or after January 1, 2018. Early adoption is permitted. The Group plans to adopt the new standard on the required effective date using the modified retrospective method. Consequently, the Group will apply IFRS 15 retrospectively only to those contracts effective on January 1, 2018, recognizing the cumulative effect of initially applying the standard as an adjustment to the opening balance of retained earnings (or another category of equity, if appropriate) as of the annual reporting period that includes the date of initial application. It not required to restate comparative periods.

This new Standard introduces a general framework for recognition and measurement of revenue, based on the core principle that revenues are recognized for an amount that reflects the consideration to which the entity expects to be entitled in exchange for transferring promised goods or services to customers. This core principle shall be applied using a five-step approach to revenue recognition: (1) identify the contract with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contracts; and (5) recognize revenue when (or as) the entity satisfies a performance obligation.

IFRS 15 requires more detailed disclosures than the current requirements to provide further information about the nature, amount, timing and certainty of revenue and cash flows derived from contracts with clients. The disclosure requirements represent a significant change as compared to current practice and increase significantly the volume of disclosures to be included in the Group’s financial statements.

In April 2016, the IASB issued amendments to IFRS 15 to clarify certain requirements and to provide additional practical expedients for transition. The amendments are mandatorily effective on the same date as the standard, i.e., January 1, 2018.

The Group carried out an implementation project, to identify and measure the possible impacts of applying IFRS 15 on its consolidated financial statements. This project involved identifying all of the revenue flows of Enel Generation Chile and its subsidiaries, knowledge of the traditional practices of the business, a comprehensive evaluation of each kind of contract with customers and determining the methodology for recording this revenue under the standards. The evaluation was performed paying special attention to those contracts presenting key aspects of IFRS 15 and particular characteristics of interest to the Group, such as identifying contractual obligations; contracts with multiple obligations and recognition opportunities; contracts with variable compensation; significant financing component; analysis of principal versus agent; existence of service guarantees; and recognition of costs to obtaining and fulfilling a contract.

The Enel Generación Chile Group  participates in the electrical energy generation, transmission and distribution businesses, and related activities. Based on the nature of the goods and services offered and the characteristics of its revenue flows streams, the Group does not expect that application of IFRS 15 will have a material impact on the consolidated financial statements of Enel Generación Chile and subsidiaries.

- Sale and transportation of electricity: The main source of revenue of Enel Generación Chile is from the sale of a series of goods and services whose control is transferred over time, since the client receives and consumes simultaneously the

F-19

benefits provided by the Group. According to the criteria under IFRS 15, the Group will continue recognizing revenue over time, instead of at a given moment in time.

- Sale of other goods and services: Correspond mainly the sale of supplementary electrical-related goods and to, services whose control is transferred to the customer at a point in time. Revenue is recognized when the control of the good or service has been transferred to the customer, i.e. when the customer obtains substantially all of the benefits from the asset and the ability to direct its use. Application of the standard will not change the calendar or the amount of revenue recognized pursuant to these agreements.

The Group is assessing the necessary changes and improvements in the systems, internal control, policies and procedures  in order to comply with the new disclousures requirements of IFRS 15.

IFRS 16 Leases

In January 2016, the IASB issued IFRS 16 which establishes recognition, measurement, presentation and disclosure principles for lease agreements. IFRS 16 supersedes IAS 17 “Leases”, IFRIC 4 “Determining whether an Arrangement contains a Lease”, SIC-15 “Operating Leases—Incentives” and SIC-27 “Evaluating the Substance of Transactions Involving the Legal Form of a Lease”.

The standard is effective for annual periods beginning on or after January 1, 2019. Early application is permitted for entities that apply IFRS 15 at or before the date of initial application of IFRS 16. The Group does not plan to adopt the standard early.

Although IFRS 16 subtantially retains the definition of a lease in IAS 17, the main change is the incorporation of the “control” concept within the new definition. In relation to the accounting treatment for a lessee and a lessor, the new Standard states the following:

i) Lessee accounting: IFRS 16 requires lessees to account for all leases under a single model, similar to accounting for finance leases under IAS 17. As a result, at the date of commencement of a lease, the lessee will recognize on the statement of financial position a right to use asset and a lease liability for the future payments. Subsequent to initial recognition it will recognize in the statement of profit or loss the depreciation expense of the asset separately from the interst related to the liability. The standard provides two voluntary recognition exceptions for low-value leases and short-term leases.

ii) Lessor accounting: does not change substantially from the current model of IAS 17. The lessor will continue to classify leases under the same principles of the current standard as operating or financial leases.

IFRS 16 provides a series of practical expedients for the transition, both for the definition of a lease and for retrospective application of the standard. The Group has not yet decided if it will use certain or all of the practical expedients.

The Group is currently carrying out an assessment of the potential impact of IFRS 16 on its consolidated financial statements. The quantitative effect will depend on, among others, the chosen transition method, the extent to which the Group uses the practical expedients and recognition exemptions and any additional lease contract entered into by the Group in the future.

IFRIC 22 – Foreign Currency Transactions and Advance Consideration

This Interpretation clarifies the date of the transaction for the purpose of determining the exchange rate to use in foreign currency transactions when the consideration is paid or received before recognizing related revenues, expenses or assets. For this purpuses, the date of the transaction is the date on which an entity initially recognizes the non-monetary asset or non-monetary liability arising from the payment or receipt of advance consideration.

The Interpretation is effective for annual periods beginning on or after January 1, 2018. Early application is permitted.

The Group expects that this new Interpretation will no have a material effect on the consolidated financial statements of Enel Generación Chile and its subsidiaries.

IFRIC 23 – Uncertainty over Income Tax Treatments

In June 2017, the IASB issued IFRIC 23 to clarify the application of recognition and measurement requirements in IAS 12, Income Taxes when there is uncertainty over income tax treatments. The Interpretation specifically addresses the following: whether an entity considers uncertain tax treatments separately; the assumptions an entity makes about the examination of tax treatments by taxation authorities; how an entity determines taxable profit (loss), tax bases, unused tax losses, unused tax credits and tax rates; and how an entity considers changes in facts and circumstances.

The Interpretation is effective for annual periods beginning on or after January 1, 2019. Early application is permitted.

The Group’s management is currently assessing the potential impact that IFRIC 23 will have on its consolidated financial statements on its initial application.

New Interpretations and Amendments to Standards	Effective date
Annual Improvements to IFRS (Cycles 2014-2016) Annual improvements correspond to a series of limited scope amendments clarifying, correcting or eliminating redundancy in the following standards: IFRS 1 “First-time Adoption of IFRS”, IFRS 12 “Disclosures of Interests in Other Entities” and IAS 28 “Investments in Associates and Joint Ventures”.	Annual periods beginning on or after January 1, 2018.
Classification and Measurement of Share-based Payment Transactions (Amendments to IFRS 2) These amendments specify accounting requirements for: (i) performance conditions for cash-settled share-based payments;(ii) the classification of withholding tax obligations for share-based payment transactions with net settlement features; and (iii) the accounting for modifications of share-based payment transactions from cash-settled to equity-settled.	Annual periods beginning on or after January 1, 2018
Transfers of Investment Property (Amendments to IAS 40) The IASB issued this amendment to clarify that a change in management’s intentions for the use of a property by itself does not constitute evidence of a change in use and is not a sufficient reclassification criteria.	Annual periods beginning on or after January 1, 2018
Amendments to IFRS 9: Prepayment features with negative compensation
The amendments allow entities to measure prepayable financial assets with negative compensation at amortized costo or at fair value through other comprehensive income upon compliance of certain specific condition, instead of being measured at fair value through profit or loss.	Annual periods beginning on or after January 1, 2019
Amendments to IAS 28: Long-term interests in Associates and Joint Ventures
The IASB issued these amendments to clarify that an entity that applies IFRS 9 to long-term interests in an associate or joint venture that form part of the net investment in the associate or joint venture but to which the equity method is not applied	Annual periods beginning on or after January 1, 2019
Annual Improvements to IFRS (Cycle 2015-2017)

F-21

Annual improvements correspond to a series of limited scope amendments that clarify the wording in an IFRS Standard or correct relatively minor oversights or conflicts between existing requirements of IFRS Standards: IFRS 3 “Business combination”, IFRS 11 “Joint arrangements”, IAS 12 “Income taxes” and  IAS 23 “Borrowing costs”.	Annual periods beginning on or after January 1, 2019
Amendment to IFRS 10 and IAS 28: Sale or Contribution of Assets
The amendment corrects an inconsistency between IFRS 10 “Consolidated Financial Statements” and IAS 28 “Investments in Associates and Joint Ventures” relating to the accounting treatment of the sale or contributions of assets between an Investor and its Associate or Joint Venture. The IASB decided to postpone the effective date of application of the amendment, until obtaining the results of its research Project on the equity method of accounting.	Effective date deferred indefinitely

In Management’s opinion, the foregoing amendments and annual improvements is not expected to have a significant effect on the consolidated financial statements of the Enel Generación Chile and its subsidiaries.

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 Company’s Management have been used to quantify some of the assets, liabilities, revenue, expenses and commitments recognized in them.

The most important areas where crititical judgment was required are:

- The identification of Cash Generating Units (CGU) for impairment testing (see Note 3.d).

- The hierarchy of information used to measure assets and liabilities at fair value (see Note 3.g).

The estimates refer basically to:

- The valuations performed to determine the existence of impairment losses in assets and goodwill (see Note 3.d).

- The assumptions used to calculate the actuarial liabilities and obligations with employees, such as discount rates, mortality tables, salary increases, etc. (see Notes 3.l.1 and 22).

- The useful lives of property, plant and equipment, and intangible assets (see Notes 3.a and 3.c).

- The assumptions used to calculate the fair value of financial instruments (see Notes 3.g and 19).

- Certain assumptions inherent in the electricity system affecting transactions with other companies, such as production, customer billings, energy consumption, that allow for estimating electricity system settlements that must occur on the corresponding final settlement dates, but that are pending as of the date of issuance of the consolidated financial statements and could affect the balances of assets, liabilities, income and expenses recognized in the financial statements (see Appendix 6.2).

- The probability that uncertain or contingent liabilities will be incurred and their related amounts (see Note 3.l).

- Future disbursements for closure of facilities and restoration of land, as well as discount rates to be used (see Note 3.a).

- The tax results of the various subsidiaries of the Group that will be reported to the respective tax authorities in the future, and that have been used as the basis for recording different balances related to income taxes in these consolidated financial statements (see Note 3.o).

F-22

- The fair value of assets acquired and liabilities assumed, and any pre-existing interest in an entity acquired in a business combination.

Although these judgments and estimates have been based on the best available information as of the issuance date 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 of judgments and estimates in the corresponding future consolidated financial statements.

2.3.1Changes in accounting estimates

The Company carried out a new study on useful lives allocated to the Group’s main items of property, plant and equipment. The results of such study indicated that there is sufficient evidence to conclude that it is necessary to revise the remaining useful lives of certain assets, so as to better reflect the period over which these assets are expected to be available for use.

Based on above, beginning on January 1, 2017, Enel Generación Chile revised the remaining useful lives of certain items of its property, plant and equipment. This change in accounting estimate resulted in a lower depreciation expense of ThCh$11,023,983 for the year ended December 31, 2017.

2.4 Subsidiaries

Subsidiaries are defined as those entities controlled either directly or indirectly by Enel Generación Chile S.A. 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 thses returns.

Enel Generación Chile has power over its subsidiaries when it holds the majority of the substantive voting rights or, should that not be the case, when it has rights granting the practical ability to direct the entities’ relevant activities, that is, the activities that significantly affect the subsidiary’s results.  

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 elements of control listed above.

Subsidiaries are consolidated as described in Note 2.7.

Appendix 1 “Enel Generación Chile Group Entities” to these consolidated financial statements, describes the relationship of the Company with each of its subsidiaries.

2.4.1 Changes in the scope of consolidation

On March 1, 2016, as part of the corporate reorganization and as a result of the spin-off described in Note 5.3, all subsidiaries that were part of the generation and distribution businesses outside of Chile have been deconsolidated, which are detailed in Appendix 2. The effects of this transaction in the consolidated financial statements of Enel Generación Chile are described in Note 5.3.

2.4.2 Unconsolidated companies with an ownership interest of over 50%

Although the Group holds more than a 50% ownership interest in Centrales Hidroeléctricas de Aysén S.A., it is considered a “joint venture” since the Group, through contracts or agreements with shareholders, exercises joint control of this entity. As of December 31, 2017, the investment that the Group has in Centrales Hidroeléctricas de Aysén, S.A. has been classified as non-current assets held to distribute to the owners (see notes 3.j, 5.1. and 12).

2.5 Investments in associates

Associates are those entities in which Enel Generación Chile, either directly or indirectly, exercises significant influence.

Significant influence is the power to participate in the financial and operational policy decisions of the associate but is not control or joint control over those policies. In assessing significant influence, the Group takes into account the existence and effect of potential exercisable voting rights or convertible rights at the end of each reporting period, including potential voting

F-23

rights held by the Company or other entities. In general, significant influence is presumed to be those cases in which the Group has more than 20% of the voting power of the investee.

Associates are accounted for under equity method as described in Note 3.h.

Appendix 3 “Associates and Joint Ventures” to these consolidated financial statements, describes the relationship of the Company with each of these companies.

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, in other words, 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 incorporated to the consolidated financial statements using the equity method, as described in Note 3.h.

- 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 incorporated to the consolidated financial statements recognizing the interest in the assets and liabilities held in the joint operation. At the end of the reporting period, the Group does not have any joint arrangements that qualify as joint operations.

In determining the type of joint arrangement in which it is involved, the management of the Group 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.

Currently, the Company is not involved in any joint arrangement that qualifies as a joint operation.

Appendix 3 “Associates and Joint Ventures” to these consolidated financial statements describes the relationship of the Company and each of these companies.

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 from intra-group transactions have been made.

The comprehensive income of subsidiaries is included in the consolidated statement of comprehensive income from the date when the parent company obtains control of the subsidiary and until the date on which it loses control of the subsidiary.

The operations of the parent company and its subsidiaries have been consolidated under the following basic principles:

1. At the date the parent 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 for the period 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, the Group chooses whether to measure the non-controlling interests in the acquiree at fair value or at the proportional share of the net identifiable assets acquired.

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

F-24

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 on events and circumstances that existed on the acquisition date, but which were unknown to the management at that time. Comparative information for prior periods presented in the financial statements is revised as needed, including making any change in depreciation, amortization or other income effects recognized in completing the initial accounting.

For business combinations achieved in stages, the Company’s previously held equity interest in the acquiree is remeasured to its acquisition-date fair value and the resulting gain or loss, if any, is recognized in profit or loss.

2. Non-controlling interests in equity and in comprehensive income of the subsidiaries are presented, respectively, under the line items “Total Equity: Non-controlling interests” in the consolidated statement of financial position and “Net income attributable to non-controlling interests” and “Comprehensive income (loss) attributable to non-controlling interests” in the consolidated statement of comprehensive income.

3. The financial statements of the Group companies with functional currencies other than the Chilean peso are translated as follows:

a. For assets and liabilities the prevailing exchange rate on the closing date of the financial statements is used.

b. For items of the comprehensive income, the average exchange rate for the period is used (unless this average is not a reasonable approximation of the cumulative effect of the exchange rates in effect on the dates of the transactions, in which case the exchange rate in effect on the date of each transaction is used).

c. For equity accounts the historical exchange rate from the date of acquisition or contribution is used, and retained earnings are translated at the average exchange rate at the date of origination.

d. Exchange differences arising in translation of financial statements are recognized in the item “Foreign currency translation gains (losses”) within the consolidated statement of comprehensive income in other comprehensive income (see Note 23.2).

4. Balances and transactions between consolidated companies were fully eliminated in the consolidation process.

5. Changes in the ownership interests in subsidiaries that do not result in the Group obtaining or losing control are recognized as equity transactions. The carrying amounts of the controlling and non-controlling interests are adjusted to reflect the changes in their relative interests in the subsidiaries. Any difference between the amount by which the non-controlling interests are adjusted and the fair value of the consideration paid or received is recognized directly in equity attributable to shareholders of the Parent.

6. Business combinations between entities under common control are accounted for using, as a reference, the ‘pooling of interest’ method. Under this method, the assets and liabilities involved in the transaction remain reflected at the same carrying amounts at which they were recognized in the ultimate controlling company, although subsequent accounting adjustments may need to be made to align the accounting policies of the companies involved.

Any difference between assets and liabilities contributed to the consolidation and the consideration paid is recorded directly in equity, as a charge or credit to “Other reserves”. The Group does not restate comparative periods in its financial statements for business combinations under common control.

F-25

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 measured at acquisition cost, net of accumulated depreciation and any impairment losses they may have experienced. In addition to the price paid to acquire each item, the cost also includes, where applicable, the following:

- Financing expenses accrued during the construction period that are directly attributable to the acquisition, construction, or production of qualified assets, which require a substantial period of time before being ready for use such as, for example, electricity generation or distribution facilities. The Group defines “substantial period” as one that exceeds 12 months. The interest rate used is that of the specific financing or, if none exists, the weighted average financing rate of the company carrying out the investment (see Note 15.4.a).

- Employee expenses directly related to construction in progress (see Note 15.4.b).

- Future disbursements that the Group will have to make to close their facilities are incorporated into the value of the asset at fair value, recording in the accounting the corresponding provision for dismantling or restoration. The Group reviews its estimate of these future disbursements on a yearly basis, increasing or decreasing the value of the asset based on the results of this estimate (see Note 21).

Items for construction work in progress 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 increasing the cost of the corresponding assets.

The replacement or overhaul of entire components that increase the asset’s useful life or economic capacity are recognized as an increase in cost for the respective assets, derecognizing the replaced or overhauled components.

Expenditures for periodic maintenance, conservation and repair are recognized directly as an expense for the period in which they are incurred.

The Group, based on the outcome of impairment testing performed as explained in Note 3.d), considers that the carrying amount of assets does not exceed their recoverable amount.

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 companies expect to use the assets. Useful life estimates and residual values are reviewed on an annual basis and if appropriate, adjusted prospectively.

The following are the main categories of property, plant and equipment with their respective estimated useful lives:

Categories of Property, plant and equipment	Years of estimated useful lives (*)
Buildings	10 – 50
Plant and equipment	5 – 65
IT equipment	3 – 15
Fixtures and fittings	2 – 35
Motor vehicles	5 – 10

F-26

Additionally, the following table sets forth more details on the useful lives of plant and equipment items:

Categories of Property, plant and equipment	Years of estimated useful lives (*)
Generating facilities:
Hydroelectric plants
Civil engineering works	10 – 65
Electromechanical equipment	10 – 40
Coal / fuel plants	20 – 40
Combined cycle plants	10 – 25
Renewable energy power plants	20
Natural gas transport facilities:
Pipelines	20

(*) See Note 2.3.1

Land is not depreciated since it has an indefinite useful life.

Gains or losses that arise from the sale or disposal of items of property, plant, and equipment are recognized as “Other gains (loses)” in the comprehensive income statement and are calculated by deducting the net carrying amount of the asset and any sales costs from the consideration received in the sale.

b) Goodwill

Goodwill arising from business combinations, and reflected upon consolidation, represents the excess value of the consideration paid plus the amount of any non-controlling interests over the Group’s share of the net value of the assets acquired and liabilities assumed, measured at fair value at the acquisition date. If the accounting for a business combination is completed within the following year after the acquisition date, and so is the goodwill determination, the entity recognizes the corresponding adjustments to the provisional amounts as if the accounting for the business combination had been completed at the acquisition date (see Note 2.7.1).  

Goodwill arising from acquisition of companies with functional currencies other than the Chilean peso is measured in the functional currency of the acquired company and translated to Chilean pesos using the exchange rate effective as of the date of the statement of financial position.

Goodwill is not amortized; instead, at the end of each reporting period or when there are indicators that an impairment might have occurred, the Company estimates whether any impairment loss has reduced its recoverable amount to an amount less than the carrying amount and, if so, it impairment loss is immediately recognized in profit or loss (see Note 3.d).  

c) 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 they may have experienced.  

Intangible assets are amortized on a straight line basis during their useful lives, starting from the date when they are ready for use, except for those with an indefinite useful life, which are not amortized. As of December 31, 2017 and 2016, there are no significant amounts in intangible assets with an indefinite useful life.

The criteria for recognizing these assets impairment losses and, if applicable, recovery of impairment losses recognized in previous periods are explained in Note 3.d below.

An intangible asset is derecognized on disposal, or when no future economic benefits are expected from use or disposal.

Gains or losses arising from derecognition of an intangible asset, measured as the difference between the net disposal proceeds and the carrying amount of the asset, are recognized in profit or loss when the asset is derecognized.

F-27

The criteria for recognizing these assets’ impairment losses and, if applicable, recovery of impairment losses recorded in previous periods are explained in Note 3.d below.

c.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.  

Expenditures on research activities are recognized as an expense in the period in which they are incurred.

c.2) Other intangible assets

Other intangible assets correspond to computer software, water rights, and easements. They are initially recognized at acquisition or production cost and are subsequently measured at cost less accumulated amortization and impairment losses, if any.

Computer software is amortized (on average) over four years. Easements and water rights have indefinite useful lives and, therefore, are not amortized.

d) Impairment of non-financial assets

During the period, and principally at the end of each reporting period, the Company evaluates whether there is any indication that an asset has been impaired. If any such indication exists, the Company estimates the recoverable amount of that asset to determine the amount of the impairment loss. In the case of identifiable assets that do not generate cash flows independently, the Company 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, in the case of CGUs to which goodwill or intangible assets with indefinite useful lives have been allocated, a recoverability analysis is performed routinely at each period end.

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, the Company uses value-in-use criteria in practically all cases.  

To estimate value in use, the Group prepares future pre-tax cash flow projections based on the most recent budgets available. These budgets incorporate management’s best estimates of a CGUs’ revenue and costs using sector projections, past experience and future expectations.

In general, these projections cover the next five 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 and country in which the Group operates. As of December 31, 2017 future cash flows projections were extrapolated using the growth rate 3.1%.

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. As of December 31, 2017, the Group applied the pre-tax discount rate 10.7%, expressed in nominal terms.

If the recoverable amount of the CGU is estimated to be less than its carrying amount, an impairment loss is recognized in the consolidated statement of comprehensive income in the line item “Reversal of impairment loss (impairment loss) recognized in profi or loss””. The impairment is first allocated to reduce the carrying amount of any goodwill allocated to the CGU, and then on a pro rata basis to the other carrying amount of each asset in the unit. The carrying amount of an asset is not reduced below the highest of fair value less costs of disposal, its value in use; or zero.

Impairment losses recognized for an asset (other than goodwill) in prior periods are reversed when there are indications that the impairment loss no longer exists or may have decreased, thus increasing the asset’s carrying amount with a credit to earnings. The increase in the asset’s carrying amount shall not exceed that carrying amount that would have been

F-28

determined had no impairment loss been recognized for the asset. Goodwill impairment losses are not reversed in subsequent periods.

e) Leases

In order to determine whether an arrangement is, or contains, a lease, the Group assesses the economic substance of the agreement, in order to determine whether fulfillment of the arrangement depends on the use of a specific asset and whether the agreement conveys the right to use an asset. If both conditions are met, at the inception of the arrangement the Group separates the payments and other considerations relating to the lease, at their fair values, from those corresponding to other components of the agreement.

Leases that substantially transfer all the risks and rewards of ownership to the Group are classified as finance leases. All others leases are classified as operating leases.

Finance leases in which the Group acts as a lessee are recognized at the inception of the arrangement. At that time, the Group records an asset based on the nature of the lease and a liability for the same amount, equal to the fair value of the leased asset or the present value of the minimum lease payments, if the latter is lower. Subsequently, the minimum lease payments are apportioned between finance expenses and reduction of the lease obligation. Finance expenses are recognized immediately in the income statement and allocated over the lease term, so as to achieve a constant interest rate on the remaining balance of the liability. Leased assets are 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.

In the case of operating leases, payments are recognized as an expense in the case of the lessee and as income in the case of the lessor, both on a straight-line basis, over the term of the lease unless another type of systematic basis of distribution is deemed more representative.

f) 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.

f.1) Financial assetsother 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.h and 12) and non-current assets and disposal groups held for sale or distribution to owners (see Note 3.j), into four categories:

- Loans and trade and other receivables: These financial assets, that are not quoted in the active market, are measured at amortized cost, which is the initial fair value minus principal repayments made, plus accrued interest, calculated using the effective interest method, minus any reduction through the use of an allowance account for impairment or uncollectibility.

The effective interest method is used to calculate the amortized cost of a financial asset or liability (or group of financial assets or financial liabilities) and is charged to finance income or cost over the relevant period. The effective interest rate is the discount rate that exactly matches discounts the estimated future cash flows to be received or paid over the expected life of the financial instrument (or, when appropriate, over a shorter period) to the net carrying amount of the financial asset or financial liability.

- Held-to-maturity investments: Investments quoted in an active market that the Group intends to hold and is capable of holding until their maturity are accounted for at amortized cost as defined in the preceding paragraph.

- Financial assets at fair value through profit or loss: This category includes the trading portfolio and those financial assets that have been designated as such upon initial recognition and that are managed and evaluated on a

F-29

fair value basis. They are measured in the consolidated statement of financial position at fair value, with changes in value recognized directly in income when they occur.

- Available-for-sale financial assets: These are financial assets specifically designated as available for sale or that do not fit within any of the three preceding categories. They are almost all financial investments in equity instruments.

These financial assets are recognized in the consolidated statement of financial position at fair value when it can be reliably determined. For investments in equity instruments in unlisted companies or companies with lower levels of liquidity, normally the fair value cannot be reliably measured. When this occurs, those investments in equity instruments are measured at cost less impairment losses, if any.

Changes in fair value, net of tax, are recognized in other comprehensive income, until the investments are disposed of, at which time the amount accumulated in other comprehensive income is reclassified to profit or loss.

If the fair value is lower than cost, and if there is objective evidence that the asset has been more than temporarily impaired, the difference is recognized directly in profit or loss.

Purchases and sales of financial assets are accounted for using their trade date.

f.2) Cash and cash equivalents

This item within the consolidated statement of financial position includes cash and bank balances, time deposits with original maturity of less than or equal to 90 days, and other highly liquid investments (with original maturity of less or equal to 90 days) that are readily convertible to cash and are subject to insignificant risk of changes in value.

f.3) Impairment of financial assets

The following criteria are used to determine if a financial asset has been impaired:

- For trade receivables in the electricity generation, transmission and distribution segments, the Company’s policy is to recognize impairment losses based on the aging of past-due balances. This is the policy generally applied except in cases where a specific collective basis analysis is recommended, such as in the case of receivables government-owned companies (see Note 8).

- In the case of receivables of a financial nature, included in the loans and trade and other receivables and held-to-maturity investments categories, impairment is determined on case-by-case basisand it is measured as the difference between the carrying amount and the present value of estimated future cash flows, discounted at the original effective interest rate (see Notes 7 and 19).

- In the case of financial investments available-for-sale, impairment criteria are detailed in Note 3.f.1.

f.4) Financial liabilities other than derivatives

Financial liabilities are recognized based on cash received, 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.f.1).  

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 recognized in the statement of financial position and for fair value disclosure purposes as shown in Note 19.2.b, debt has been divided into fixed interest rate debt (hereinafter “fixed-rate debt”) and variable 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 a variable interest rate, i.e., each coupon is established at the beginning of each period based on the reference interest rate. All debt has been measured by discounting expected future cash flows with a market interest rate curve based on the payment currency.  

F-30

f.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 recognized at fair value at the end of each reporting period as follows: if their fair value is positive, they are recognized within “Other financial assets”; and if their fair value is negative, they are recognized within “Other financial liabilities”. For derivatives on commodities, the positive fair value is recognized in “Trade and other receivables”, and negative fair values are recognized in “Trade and other payables”.

Changes in fair value are recognized directly in profit or loss, except when the derivative has been designated for hedge accounting purposes as a hedge instrument (in a cash flow hedge) and all of the conditions for applying hedge accounting established by IFRS are met, including that the hedge be highly effective. In this case, changes are recognized as follows:

- Fair value hedges: The underlying portion for which the risk is being hedged (hedged risk) and the hedge instrument are measured at fair value, and any changes in value of both items are recognized in the consolidated statement of comprehensive income by offsetting the effects in the same comprehensive income statement account.

- 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 known as “Reserve for cash flow hedges”. The cumulative loss or gain in this reserve is transferred to the consolidated statement of comprehensive income to the extent that the hedged item impacts the consolidated statement of comprehensive income because of the hedged risk, offsetting the effect in the same comprehensive income statement account. Gains or losses from the ineffective portion of the hedging relationship are recognized directly in the consolidated statement of comprehensive income.

A hedge relationship is considered highly effective when changes in fair value or in cash flows of the underlying item directly attributable to the hedged risk are offset by changes in fair value or cash flows of the hedging instrument, with an effectiveness ranging from 80% to 125%.  

As a general rule, long-term commodity purchase or sale agreements are recognized in the consolidated 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: (i) in the case of fuel purchase agreements its used to generate electricity; (ii) in the case of electrical energy purchased for sale, its sale to the end-customers; and, (iii) in the case of electricity sales its sale to the end-customers.

- The Group’s future projections evidence the existence of these agreements for its own use.

- Past experience with agreements evidence that they have been utilized for its own use, except in certain isolated cases when for exceptional reasons or reasons associated with logistical issues have been used beyond the control and projection of the Group.

- The agreement does not stipulate settlement of differences and the parties have not made it a practice to settle similar contracts with differences 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. Thus, the purpose of fuel purchase agreements is to use them to generate electricity, electricity purchase contracts are used to sell to end-customers, and electricity sale contracts are used to sell its 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 principal 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 recognized separately and changes in value are accounted for directly in the statement of comprehensive income.

f.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, if the contractual rights are retained, the Company 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 ownership of the financial asset, or, if it has neither transferred nor retained substantially all the risks and rewards, when it does not retain control of the financial asset.

Transactions in which the Group retains substantially all the inherent risks and rewards of ownership of the transferred asset, it continues recognizing the transferred asset in its entirety and recognizes a financial liability for the consideration received. Transactions costs are recognized in profit and loss by using the effective interest method (see Note 3.f.1).

Financial liabilities are derecognized when they are extinguished, that is, when the obligation arising from the liability has been paid or cancelled, or has expired.

f.7) Offsetting of financial assets and 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 set-off recognized amounts; and

- the company intends to settle them on a net basis, or to simultaneously realize the asset and settle the liability.

The right of set-off 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 of the counterparties.

f.8) Financial guarantees

The financial guarantee contracts, defined as the guarantees issued by the Company and its subsidiaries 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 determined in accordance with the accounting policy in Note 3.l; and

- The amount initially recognized less, when appropriate, cumulative amortization recognized in accordance with the revenue recognition policies described in Note 3.p.

g) 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.  

F-32

In estimating fair value, the Group uses valuation techniques that are appropriate for the circumstances and for which there is sufficient data to conduct the measurement, maximizes the use of relevant observable data and minimizes the use of unobservable data.

Given the hierarchy of the entry 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 within 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 carried out using external tools such as Bloomberg); and

Level 3: Inputs for assets or liabilities that are not based on observable market data (unobservable inputs).

When measuring fair value, the Group takes into account the characteristics of the asset or liability, particularly:

- 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 in 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 on 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 close 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 (creditor or borrower 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, it is permitted to measure the fair value on a net basis. 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 liabilities measured at fair value are presented in Note 19.3.

h) Investments accounted for using the equity method

The Group’s interests in joint ventures and associates are recognized using the equity method.

Under the equity method, 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 its equity that the Group’s interest represents in its capital, adjusted for, if appropriate, the effect of transactions with subsidiaries plus any goodwill generated in acquiring the company. If the resulting amount is negative, zero is recognized for that investment in the statement of financial position, unless the Group has a present obligation (either legal or implicit) to support the company’s negative equity position, in which case a provision is recognized.

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.

F-33

Dividends received from these companies are deducted from the value of the investment, and any profit or loss obtained from them to which the Group is entitled based on its interest is recognized under “Share of profit (loss) of investments accounted for using equity method”.  

Appendix 3 “Associates and Joint Ventures” to these consolidated financial statements, describes the relationship of the Company with each of these companies.

i) Inventories

Inventories are measured at their weighted average acquisition cost or the net realizable value, whichever is lower. Net realizable value is the estimated selling price in the ordinary course of business less the estimated costs of completion and the estimated costs necessary to make the sale.

The cost of inventories includes all costs of purchase and all necessary costs incurred in bringing the inventories to their present location and condition.Trade discounts, rebates and other similar items are deducted in determining the costs of purchase.

j) Non-current assets and disposal groups and liabilities associated held for sale or distribution to owners and discontinued operations

Non-current assets (including property, plant and equipment, intangible assets, investments accounted for using the equity method and joint ventures) and disposal groups (a group of assets to be disposed of and the liabilities directly associated with those assets) are classified as:

- held for sale if their carrying amount will be recovered principally 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 this to be the case, the assets must be available for immediate sale or distribution in their present condition and the sale or distribution must be highly probable. For the sale or distribution to be highly probable, actions to complete the sale or distribution 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 should indicate that it is unlikely that significant changes to the sale or distribution will be made or that the sale or distribution will be withdrawn. 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.

Non-current assets or disposal groups 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 depreciations, amortizations or revaluations that would have been recognized if they had not been classified as held for sale or held for distribution to owners and their recoverable amount at the date of subsequent decision where would be reclassified as non-current assets.

Non-current assets held for sale or held for distribution to owners 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 line item entitled “Non-current assets and disposal groups held for sale or distribution to owners”, and the respective liabilities are presented as a line item entitled “Liabilities associated with disposal groups held for sale or distribution to owners”.

F-34

The Group classifies as discontinued operations those component of the Group that either have been disposed of, or are classified as held for sale and:

- represents 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.

The components of profit or loss after taxes from discontinued operations and the post-tax gain or loss recognized on the measurement to fair value less costs to sell or on the disposal of the assets or groups constituting the discontinued operation are presented as a single line item in the consolidated comprehensive income statement as “Income after tax from discontinued operations”.

k)

Treasury shares

Treasury shares are deducted from 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 “Equity – Retained earnings”, without affecting profit or loss for the period.

l) 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 the 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 a finance cost.  Incremental legal cost expected to be incurred in resolving a legal claim is 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 they are incurred.  Significant contingent liabilities are disclosed unless the likelihood of an outflow of resources embodying economic benefits is remote.

l.1) Provisions for post-employment benefits and similar obligations

The Company and some of the subsidiaries have pension and similar obligations with their employees. These obligations, which can be defined benefits and defined contributions, are basically formalized through pension plans, except for certain non-monetary benefits, mainly electricity supply commitments, which, due to their nature, have not been externalized and are covered by the related in-house provisions.

For defined benefit plans, the cost of providing benefits is determined using the Projected Unit Credit Method, with actuarial valuations being carried out at the end of each reporting period. Past service costs relating to changes in benefits are recognized immediately.

F-35

The defined benefit plan obligations in the statement of financial position represent the present value of the accrued obligations, adjusted, once the fair value of the different plans’ assets has been deducted, if any.

Actuarial gains and losses arising in measurement of both the plan liabilities and the plan assets are recognized directly in other comprehensive income.

m) Translation of foreign currency balances

Transactions carried out 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, any differences that arise 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 exchange losses, net” in the consolidated statement of comprehensive income.

Likewise, at the end of each reporting period, receivable or payable balances denominated in a currency other than each entity’s functional currency are translated using the closing exchange rate. Any differences are recognized as “Foreign currency exchange losses, net” in the consolidated statement of comprehensive income.

The Group has established a policy to hedge the portion of revenue from its subsidiaries 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 reclassified to profit or loss when the hedged cash flows impact profit or loss. This term has been estimated at ten years.

n) Current/non-current classification

In these consolidated statements of financial position, assets and liabilities expected to be recovered or settled within twelve months are presented as current items, 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 credit agreements with long-term maturities, such obligations are classified as long-term liabilities.

o) Income taxes

Income tax expense for the period is determined as the sum of current taxes from the Group’s different subsidiaries and results from applying the tax rate to the taxable income for the period, after permitted deductions 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 apply 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 make use of 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 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.

F-36

Deferred tax liabilities are recognized for all temporary differences, except 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 recognized in profit or loss or in equity, 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 doubts exist about their tax realization, in which case they are not recognized until they are effectively realized, or when they correspond to specific tax incentives, in which case they are recognized as government grants.

At the end of each reporting period, the Group reviews the deferred taxes assets and liabilities recognized, and makes, if any, necessary corrections based on the results of its review.

Deferred tax assets and deferred tax liabilities are offset in the consolidated statement of financial position if has a legally enforceable right to set off current taxes receivable against current tax liabilities, and only when the deferred taxes relate to income taxes levied by the same taxation authority.  

p) Revenue and expense recognition

Revenue is recognized when the gross inflow of economic benefits arising in the course of the Group’s ordinary activities in the period occurs, provided that this inflow of economic benefits results in an increase in total equity that is not related to contributions from equity participants and that these benefits can be measured reliably.

Revenues and expenses are recognized on an accrual basis and depending on the type of transaction, the following criteria for recognition are taken:

- Generation and transmission of electricity: Revenue is recognized based on physical delivery of energy and power, at prices established in the respective contracts; at prices stipulated in the electricity market by applicable regulations; or at marginal cost determined on the spot market, as the case may be. This revenue includes an estimate of the service provided and not billed as of the closing date (see Note 2.3 and Note 24).

Revenue from rendering of services is recognized, only if it can be estimated reliably, by reference to the stage of completion of the service at the end of the reporting period.

Revenue is recognized based on the economic substance of the transaction and is recognized when all of the following conditions are met:

- the entity has transferred to the buyer the significant risks and rewards of ownership of the goods;

- the entity retains neither continuing managerial involvement to the degree usually associated with ownership nor effective control over the goods sold;

- the amount of revenue can be measured reliably;

- it is probable that the economic benefits associated with the transaction will flow to the entity; and

- the costs incurred or to be incurred in respect of the transaction can be measured reliably.

Revenue is measured at the fair value of the consideration received or receivable that gives rise to the revenue.

In arrangements under which the Group will perform multiple revenue-generating activities (multiple-element arrangement), the recognition criteria are applied to the separately identifiable components of the transaction in order to reflect the substance of the transaction or to two or more transactions together when they are linked in such a way that the commercial effect cannot be understood without reference to the series of transactions as a whole. The Group excludes from revenue those gross inflows of economic benefits it receives when it acts as an agent or commission agent on behalf of third parties, and only recognizes as revenue economic benefits received for its own activity.

When goods or services are exchanged or swapped for goods or services of a similar nature and value, the exchange is not regarded as a revenue-generating transaction.

F-37

The Group recognizes the net amount of non-financial asset purchases or sale contracts that are settled for a net amount of cash or through some other financial instruments. Contracts entered into and maintained for the purpose of receiving or delivering these non-financial assets are recognized on the basis of the contractual terms of the purchase, sale, or usage requirements expected by the entity.

Finance income (expense) is recognized using the effective interest method, applicable to the outstanding principal over the repayment period.

Expenses are recognized on an accruals basis, immediately in the event of expenditures that do not generate future economic benefits or when they do not meet the requirements for recording them as assets.

q) Earnings per share

Basic earnings per share are calculated by dividing net profit attributable to shareholders of the Parent (the numerator) by the weighted average number of ordinary shares outstanding (the denominator) during the period, excluding the average number of shares of the Parent held by the Group, if any.

Total basic earnings per share are calculated as the ratio of the net profit for the year after tax from continuing and discontinued operations, less the corresponding portion attributable to non-controlling interests, and the weighted average number of common shares of the parent company outstanding during the period, excluding the average number of shares of the parent held by the Group.

r) Dividends

Article No. 79 of the Chilean Corporations Act 18,046 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 to 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 deficit from prior years must be absorbed.

As it is practically impossible to achieve a unanimous agreement given the Group’s highly fragmented share capital, at the end of each reporting period the amount of the minimum statutory dividend obligation to its shareholders is determined, net of dividends approved during the period, and then accounted for in “Trade and other payables” and “Accounts payable to related parties”, as appropriate, and recognized in Equity

The provisional and final dividends are deducted from Equity when approved by the competent body, which in the first case is normally the Board of Directors and in the second case is the shareholders as agreed at an Ordinary Shareholders’ Meeting.

s)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 expressions and corresponding 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 and other activities 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.

F-38

4.SECTOR REGULATIONS AND ELECTRICITY SYSTEM OPERATIONS

1) Regulatory framework

The electricity sector is regulated by the General Law of Electrical Services (Chilean Electricity Law), also known as DFL No. 1 of 1982, of the Ministry of Mining – whose compiled and coordinated text was established in DFL No. 4 issued in 2006 by the Ministry of Economy (the Electricity Law) – as well as by an associated Regulation (D.S. No. 327 issued in 1998).

The main authority in energy matters is the Ministry of Energy, which is responsible for proposing and driving public policies for energy matters, strengthening coordination and expediting a comprehensive look at the sector. It was born on February 1, 2010 as an autonomous agency, after years of being part of the Ministry of Mines.

Answering to the Ministry of Energy are the regulatory agency of the power sector (the National Energy Commission) and the auditing agency (Superintendency of Electricity and Fuels). The Ministry also has the Chilean Nuclear Energy Commission (CChEN), with the Energy Efficiency Agency and the National Center for Innovation and Promotion of Sustainable Energy (CIFES), which replaced the Renewable Energy Center (CER) in November, 2014.

The CNE, which has the authority to propose regulated tariffs (node prices) and to approve plans for the construction of new generating units. Besides, the SEF, supervises and oversees compliance with the laws, regulations, and technical standards that govern the generation, transmission, and distribution of electricity, as well as liquid fuels, and gas.

Furthermore, the law considers a Panel of Experts, made up of experts whose main function is to resolve any discrepancies occurring with regard to matters stipulated in the Electricity Law and in the application of other laws involving energy matters, by means of binding decrees.

From a physical viewpoint, the Chilean electrical sector is divided into three electrical grids: the Sistema Electrico Nacional (“SEN”), and two separate medium-size grids located in southern Chile, one in Aysén and the other in Magallanes. The SEN was created in November 2017 with the interconnection of the Sistema Interconectado Central (“SIC”) and Sistema Interconectado del Norte Grande (“SING”). Until the interconnection, the SIC constituted the main electrical grid of Chile, which extended longitudinally 2,400 km and connected the country from Taltal in the north to Quellón, on the island of Chiloé in the south. Besides, the SING covered the northern part of the country, from Arica down to Coloso a length of some 700 km.

The Chilean power industry has basically three activities – Generation, Transmission and Distribution. Power facilities associated with these three activities are obligated to operate in an interconnected, coordinated manner, with the main purpose of provding the market with electrical energy at minimum cost and within the standards of service quality and safety required by the electricity regulations.

As essential services, the power transmission and distribution businesses are natural monopolies; these segments are regulated as such by the Electricity Law, which requires free access to networks and regulates rates.

Two products (Energy and Power) and sundry services are provided in the electricity market. In particular, the National Electricity Coordinator is in charge of making the balances, determining the respective transfers between generating companies and calculating the marginal hourly cost, at which price the energy transfers are valued. For its part, the CNE determines the Power prices.

Consumers are classified according to the size of their demand into regulated or unregulated customers. Regulated customers are those that have a connected capacity of less than 5,000 kW. Without detriment to the above, customers with a connected power of between 500 kW and 5,000 kW may opt for a regulated or unregulated rates system.

Limits on integration and concentration

Chile has legislation in effect that defends free competition and, together with specific regulations that apply to the electricity market, defines criteria to avoid certain levels of economic concentration and/or abusive market practices.

In principle, the regulator allows the participation of companies in different activities (e.g. generation, distribution, and commercialization) as long as there is an adequate separation of each activity, for both accounting and company purposes.

F-39

Nevertheless, most of the restrictions imposed involve the transmission sector mainly due to its nature and to the need to guarantee adequate access to all agents. The Chilean Electricity Law establishes limits for participation of generation or distribution companies in the Trunk Transmission Systems and prohibits participation of Trunk Transmission Systems companies in the generation and distribution segment.

1.1. Generation segment

Generation companies must comply with the operation plan of the CISEN. However, each generation company is free to decide whether to sell its energy and capacity to regulated or unregulated customers. Any surplus or deficit between a company’s sales to its customers and its energy supply is sold to, or purchased from, other generators at the spot market price.

A power generation company may have the following types of customers:

(i) Unregulated customers: Are customers mainly industrial and mining companies, with a connected capacity higher than 5,000 kW. These consumers can freely negotiate prices for electrical supply with generators and/or distributors. Customers with capacity between 500 and 5,000 kW have the option to contract energy at prices agreed upon with their suppliers or be subject to regulated prices, with a minimum term of at least four years under each pricing system.

(ii) Distribution companies that supply power to regulated customers:distinguishing supply from its regulated and free customers. For the supply of their regulated customers, the distribution companies buy energy from the generating companies through Participation in public tenders regulated by the CNE for the supply to their free customers through bilateral contracts.

(iii) Generation Companies in Spot market: This represents energy and capacity transactions among generating companies that result from the CISEN’s coordination to keep the system running as economically as possible, where the surpluses (deficits) between a generator’s energy supply and the energy it needs to comply with business commitments are transferred through sales (purchases) to (from) other generators in the CISEN. In the case of energy, transfers are valued at the marginal cost, while node prices for capacity are set every semester by the regulators.

In Chile, the capacity that must be paid to each generator depends on an annual calculation performed according to current regulations by the CISEN, to determine the sufficiency capacity of each power plant, a value that depends mainly on the availability both of the facilities as such, and of the generation resource according to the technology.

Non-Conventional Renewable Energy

Law No. 20,257 was enacted in April of 2008 to encourage the use of Non-Conventional Renewable Energy (“NCRE”). The principal aspect of this law is that at least 5% of the energy sold by generation companies to their customers must come from renewable sources between years 2010 and 2014. This requirement progressively increases by 0.5% from 2015 until 2024, when a 10% renewable energy requirement will be reached. This law was amended in 2013 by Law No. 20,698, dubbed the “20/25 law,” as it establishes that by 2025, 20% of energy supplied will be generated by NCRE. It does not change the previous law’s plan for supplying energy under agreements in effect in July 2013.

1.2. Transmission segment

The transmission segment is comprised of a combination of lines, substations and equipment for the transmission of electricity from the production points (generators) to the centers of consumption or distribution, which do not correspond to distribution facilities. The transmission segment is divided into National Transmission System, Development Poles Transmission System, Zonal Transmission System, Dedicated Transmission System and International Interconnection Systems.

The transmission system is open access, and transmission companies may impose rights of way over the available transmission capacity under non-discriminatory conditions. The fees of the existing facilities of the National Transmission System and Zonal Transmission System is determined through a tariff setting process that is carried out every four years. In that process, the Annual Value of the Transmission is determined, which comprises efficient operation and maintenance

F-40

costs and the annuity of the investment value, determined on the basis of a discount rate fixed by the authority on a quarterly basis (minimum 7% after tax) and the economic useful life of the facilities.

The planning of the National and Zonal Transmission Systems corresponds to a regulated and centralized process, where the CISEN annually issues an expansion plan, which must be approved by the CNE.

The expansions of both systems are carried out through open tenders, distinguishing between new projects and expansion of existing facilities projects. For newprojects open tenders are considered, being the successful bidder the owner of the facilities. In the case of expansion of existing facilities, the owner of the original facilities is also the owner of its extension and has the obligation to tender its construction.

The bids correspond to the value resulting from the tender, which constitutes the income for the first 20 years from the start of operation. As of the year 21, the fees of such transmission facilities are determined as if they were existing facilities.

1.3. Distribution segment

The distribution segment is defined for regulatory purposes as all electricity supplied to end customers at a voltage no higher than 23 kW.

Distribution companies operate under a public service concession regime, having the obligation to provide service to clients submitted to regulated tariffs (clients with a connected capacity inferior to 5,000 kW, except for clients between 500 and 5,000kW-connected capacity who exercise their option to opt for an unregulated tariff). It should be noted, that clients with an unregulated tariff could negotiate their supply with any supplier (distribution or generation company) by paying a regulated usage charge for the use of the distribution network.

Regarding price regulation, the Chilean Electricity Law establishes that the distribution companies must permanently have available energy supply, on the basis of open, non-discriminatory and transparent public tenders. These bidding processes are managed by the CNE and are carried out at least five years in advance. The result of the process is a “pay as bid” contract, with an extension up to 20 years. In case of unforeseen deviations in the projections of demand, the regulator has the authority to carry out a short-term tenders. In addition, a reimbursement mechanism exists allowing supply without contract.

The tariffs setting for this sement are set every four years on the basis of costs studies in order to determine the ditribution value added (VAD). VAD determination is based on an enterprise outline efficient model and concept of typical area.

Certainly, for the process of determining VAD, the CNE classifies companies with similar distribution costs by groups named "typical areas". For each typical area both, the CNE and the distribution companies, commission studies to independent consultants to determine the associated costs with an efficient model company considering fixed costs, average energy and power losses and standard investment, maintenance and operating costs associated with the distribution. The calculation of the annual investment costs considers the New Replacement Value (NRV) of the facilities adapted to the demand, their useful life and an update rate equal to a real annual 10%.

The VAD is obtained by weighting the results of the commissioned studies by the CNE and the companies with a ratio of 2:3 and 1:3, respectively. Based on this result, the CNE structures basic tariffs and verifies that the aggregate profitability of the industry is within the established range of 10% with a margin of ± 4%.

Additionally, every four years a review of Services Associated with the calculation of VAD is carried out, which do not represent energy supply and which the Free Competition Court qualifies as subject to tariff regulation.

The Chilean distribution tariff model is a robust model, which already had nine cycles of tariff settings since the privatization of the sector.

5.  NON-CURRENT ASSETS OR GROUPS OF ASSETS FOR DISPOSAL CLASSIFIED AS HELD FOR SALE OR HELD FOR DISTRIBUTION TO OWNERS

5.1 Centrales Hidroeléctricas de Aysén S.A.

Enel Generación Chile has a 51% interest in Centrales Hidroeléctricas de Aysén S.A. (hereinafter “Hidroaysén”), whose corporate purpose was to develop, finance, own and exploit a Hydroelectric Project in Region XI Aysén, Chile.

On November 17, 2017, the Board of Directors of Hidroaysén agreed to cease the company’s activities and terminate the Hidroaysén’s electrical project. The decision was made because the forecasted value of the investment in generation and transmission for the electrical project, its related costs and the long-term market prospects indicated that the project was not economically feasible in every possible valuation scenario. Also, the significance amount of the investment and its related risks, both legal and administrative, would add a second uncertainty factor that definitively precluded continuing with the project.

On December 7, 2017, an Extraordinary Shareholders’ Meeting was held and it agreed to the early winding up of the company and how the process of liquidating the company’s assets would be carried out. The liquidation process considers distributing assets to the shareholders and it is anticipated to be completed in the first half of 2018.

On December 31, 2017, as a result of the above, the investment held by Enel Generación Chile in Hidroaysén comply with the criteria to be classified as a non-current asset held for distribution to owners, therefore, as described in note 3.j), it has been recognized at the lower of its carrying amount and fair value less costs to sell. The following table shows the carrying amount of the investment:

Equity of Centrales Hidroeléctricas de Aysén S.A.	Ownership	Carrying Amount of Centrales Hidroeléctricas de Aysén S.A.
ThCh$	%	ThCh$
8,245,555	51.00%	4,205,232

It is important to stress that, at 2014 year-end, Enel Generación Chile recorded a provision for the impairment of its interest in Hidroaysén of ThCh$69,066,857 (See note 12.1.c).

5.3 Corporate reorganization

I. General background

On April 28, 2015, the Company informed the SVS through a significant event notice, that the Board of Directors of its direct parent at that time, Enersis S.A. (currently named Enel Américas S.A.), communicated that it had decided to initiate an analysis of a corporate reorganization aimed at the separation of the activities of power generation and distribution in Chile from other activities conducted outside of Chile by Enersis S.A. (currently named Enel Américas S.A.) and its subsidiaries Empresa Nacional de Electricidad S.A. (the Company, currently named Enel Generación Chile S.A.) and Chilectra S.A. (currently named Enel Distribución Chile S.A.), while maintaining its inclusion in the Enel S.p.A. group.

In the same significant event notice, the Board of Directors of the Company reported that it had agreed to initiate studies to analyze a possible corporate reorganization consisting of the spin-off of its businesses in Chile from those outside of Chile, and the subsequent merger of the latter into a single company. Furthermore, it indicated that the objective of this reorganization was to create value for all of its shareholders, as none of these operations require the contribution of additional resources from shareholders. The possible corporate reorganization would take into account the best interests as well as all shareholders’ interests, with special attention paid to minority interests, and if it were approved, it would be subject to approval at an Extraordinary Shareholders’ Meeting..

This corporate reorganization consisted of two steps:

- Each of Enersis S.A. (currently Enel Américas S.A.) and its subsidiaries Endesa Chile and Chilectra S.A. would effect a spin-off, resulting in separation (the “Spin-off”) of the businesses in Chile and outside of Chile.

- Once the previously mentioned spin-off transactions were completed, Enersis S.A. (currently named Enel Américas S.A.) would absorb by merger the newly created companies, Endesa Américas S.A. and Chilectra Américas S.A., to which the businesses outside of Chile would be allocated, and would dissolve them without liquidation.

On December 18, 2015, the Extraordinary Shareholders' Meeting of the Company approved the demerger, subject to the conditions precedent consistent in approving the demergers of Enersis S.A. (currently Enel Américas S.A.) and Chilectra S.A. (currently Enel Distribución Chile S.A.) by their respective Extraordinary Shareholders’ Meetings, in addition to the relevant legal procedures and related matters. Also, it was agreed that the demerger would take effect from the first calendar day of the month following that in which a deed of compliance with conditions of the demerger is granted.

On March 1, 2016, having satisfied all conditions precedent, the demerger of the Company became effective and the new entity Endesa Américas S.A. began to exist, to which were allocated the shareholdings and other associated assets and liabilities of the businesses outside of Chile . Consequently, the corresponding capital decrease of the Company and other amendments to its by-laws were verified (see Note 23). On the same date, all of Enersis S.A. ownership interest in the Company were transferred to Enersis Chile S.A. (currently named Enel Chile S.A.) the new entity created from the demerger of Enersis S.A. (currently named Enel Américas S.A.) to which were allocated the generation and distribution businesses in Chile.

III. Other information

The Spin-off by the Company triggered the Company’s obligation to pay taxes in Peru for a total amount of 577 million Peruvian Soles (approximately ThCh$ 116,053,255). This tax, paid during March 2016, was generated as a result of the application of the Peruvian Income Tax Law to the transfer of the ownership interests, which the Group held in Peru, to Endesa Américas S.A. The tax is calculated as the difference between the disposal value and the acquisition cost of the ownership interests.

Because this payment was directly linked to the Spin-off, the effect has been recognized directly in equity, specifically in other reserves, following the nature of the principal transaction (transaction with shareholders in their capacity as owners).

b) Sale of GNL Quintero S.A.

On June 9, 2016, the Company entered into a share purchase agreement with Enagás Chile S.p.A. (“Enagás Chile”), a wholly-owned subsidiary of Enagás S.A., under which Enagás Chile would acquire the entire 20% ownership interest held by the Company in the associated company GNL Quintero S.A.

The sale of this investment to Enagás Chile was subject to satisfaction of customary conditions precedent for this type of transaction, which included, among others, non-exercising by the other shareholders of GNL Quintero S.A. of the preferential acquisition rights, which they possess in accordance with the terms and conditions of the shareholders agreement.

On September 14, 2016, upon satisfaction of the conditions precedent, the Company transferred the shares it held in GNL Quintero S.A. to Enagás Chile. The purchase price was US$ 197,365,113.2 million (ThCh$ 132,820,800). Cash received for GNL Quintero S.A. is included in “Other collections from the sale of equity or debt instruments belonging to other entities” of the Consolidated Statements of Cash Flows. Also see Note 30 for the net financial result of the transaction.

GNL Quintero S.A. operates a storage and regasification of Liquefied Natural Gas (LNG) plant and its related land-based Terminal for loading and unloading LNG, including facilities and network necessary to deliver LNG, through a LNG truck loading facility and delivery point’s pipelines.

c) Centrales Hidroeléctricas de Aysén S.A.

In May 2014, the Committee of Ministers revoked the Environmental Qualification Resolution (“RCA”) of the Centrales Hidroeléctricas de Aysén S.A. project, in which the Company participates by accepting some of the claims filed against this project. It is a public information that this decision was resorted before the Environmental Courts in Valdivia and Santiago. On January 28, 2015, it was made public that the water rights request made by Centrales Hidroeléctricas de Aysén S.A. has been partially rejected in 2008.

The Company has expressed its intention to promote at Centrales Hidroeléctricas de Aysén S.A. the defense for water rights and the environmental qualification granted to the project in the corresponding instances, continuing with the judicial actions already started or implementing new administrative or judicial actions that are necessary to this end, and it maintains the belief that hydric resources of the Aysén region are important for the energy development of the country.

Nevertheless, given the current situation, there is uncertainty on the recoverability of the investment made so far at Centrales Hidroeléctricas de Aysén S.A., since it depends both on judicial decisions and on definitions in the energy agenda which cannot be foreseen at present, consequently the investment is not included in the portfolio of the Company’s immediate projects. Consequently, at closing date of fiscal year 2014, the Company recognized an impairment of its participation in Centrales Hidroeléctricas de Aysén S.A. amounting to ThCh$ 69,066,857, which remains in effect as of December 31, 2017.

On December 7, 2017, an extraordinary shareholders’ meeting of this project was held, in which the early dissolution of the aforementioned was agreed to, as well the company liquidation process of assets. The liquidation process contemplates a distribution of assets to shareholders and expected to be completed during the first half of 2018.

In accordance with the above, the investment that Enel Generación Chile has in this project has been classified as non-current assets held for distribution to the owners (See Note 5.1).

F-64

The origin of goodwill as detailed below is a result of the acquisitions of the following entities, subsequently merged directly or indirectly into GasAtacama Chile S.A.:

On July 12, 2002, the Company acquired 2.51% of the shares of Empresa Eléctrica Pangue S.A. through a put option held by the minority shareholder International Finance Corporation (IFC).

On August 11, 2005, the Company acquired interest of Inversiones Lo Venecia Ltda., which held as its only asset 25% interest in the company San Isidro S.A.

Subsequently, Empresa Eléctrica Pangue S.A. and the company San Isidro S.A. were merged into Compañía Eléctrica Tarapacá S.A., the latter being the legal successor company.

On April 22, 2014, the Company purchased the 50% interest in Inversiones GasAtacama Holding Ltda. held by Southern Cross Latin America Private Equity Fund III L.P. at that time (see Note 6.d).

On October 1, 2016, Inversiones GasAtacama Holding Ltda. was merged into Compañía Eléctrica Tarapacá S.A., the latter being the legal successor company.

On November 1, 2016, Compañía Eléctrica Tarapacá S.A. was merged into GasAtacama Chile S.A., the latter being the legal successor company.

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 recovering of its carrying amount as of December 31, 2017 and 2016 (see Note 3.b).

15.7 Other information

1. As of December 31, 2017 and 2016 the Group had contractual commitments for the acquisition of property, plant and equipment amounting to ThCh$ 281,814,599 and ThCh$ 310,558,229, respectively.

2. As of December 31, 2017, and 2016 the Group does not have property, plant and equipment that was pledged as security for liabilities.

3. The Company and its Chilean subsidiaries have insurance policies for all risks, earthquake and machinery breakdown and damages for business interruption with a € 1,000 million  limit. Additionally, the Company has Civil Liability insurance to meet claims from third parties with a € 500 million  limit. The premiums associated with these policies are presented proportionally for each company in the caption “Prepaid Expenses”.

4. The condition of certain assets of the Company changed, primarily works and infrastructure for facilities built to support power generation in the SIC grid in 1998, due primarily to the installation in the SIC of new thermoelectric plants, the arrival of LNG, and new other projects. As such, a new supply configuration for the upcoming years, in which it is expected that these facilities will not be used. Therefore, in 2009, Enel Generación Chile S.A. recognized an impairment loss of ThCh$43,999,600 for these assets, which is still has not reversed. (see Note 3.d).

5. At the end of 2014, the Group recognized an impairment loss of ThCh$ 12,581,947 related to the Punta Alcalde project. This impairment loss was triggered because the current definition of the project is not fully aligned with the strategy that the Company is reformulating; particularly, with regard to technological leadership, and to community and environmental sustainability. The Company has decided to suspend the project as its profitability is still unclear (see Note 3.d).

6. At the end of 2012, the Company’s subsidiary Compañía Eléctrica Tarapacá S.A. (currently named Gas Atacama Chile S.A.) recognized an impairment loss of ThCh$ 12,578,098, to adjust the carrying amount of certain specific assets operating in the SING grid to its recoverable amount.

At the closing of 2015, a number of new facts and circumstances was evaluated by the company, which resulted in the identification of a new single CGU for all generation assets in Chile. The analysis took into account the fact that the Group performed an optimization and joint development of all assets related to generation and transmission work, centralized trade policy, with sales contracts agreed at company level and not assigned by power plant. Generation of flows depends on all the assets as a whole.

Previously, the company identified one CGU for the assets operating in the SIC grid and another one for the assets operating in theSING, under the consideration that there were two separate markets. The new scheme, approved in 2015, posed by the interconnection of SIC and SING, unifies markets and considers formation of a single price, which was illustrated by latest bids for supply to regulated customers.

Therefore, these new conditions indicated that the recognized impairment loss mentioned above has been reversed. This was based, inter alia, on the generation of additional value by the interconnection project between the SIC and SING which is expected to be operational in 2019, by improved utilization of reserves, by expanding the potential market for specific impaired assets and decreasing overall risk of the portfolio. The effects of the interconnection are considered in the five-year projections used by the company to perform impairment tests (see Note 3.d).

7. As of December 31, 2015, the Group recognized an impairment loss of ThCh$ 2,522,445 related to the wind project Waiwen. This impairment loss was a result of new assessment of the feasibility of the project performed by the Company and a conclusion that, under existing conditions to date, profitability is uncertain.

8. In line with its sustainability strategy and in order to develop community relations, the Company has decided to research new design alternatives for the Neltume project, in particular regarding the question of the discharge of Lake Neltume, which has been raised by the communities in the various instances of dialogue.

To start a new phase of research of an alternative project, which includes the discharge of water on the Fuy River in late December 2015, the Company withdrew the Environmental Impact Study. This decision applies only to the Neltume project and not to the transmission project, which continues its course on handling in the Environmental Assessment Service.

As a result of the above, as of December 31, 2015, the Group recognized a loss of ThCh$2,706,830, associated with the write down of certain assets related to Environmental Impact Study, which had been withdrawn and to other studies directly linked to the old design of assets.

Consequently in line with the new sustainability strategy and as a result of sustained dialog with the communities, the Company’s projects in the territory, namely Neltume and Choshuenco, have good prospects from the social point of view. However, given the current conditions of the Chilean electricity market, expected profitability of the Neltume and Choshuenco projects is lower than the total capitalized investment in them. As a result, at the end of 2016, the Group recognized an impairment loss of ThCh$ 20,459,461 associated with the Neltume project and ThCh$ 3,748,124 associated with the Choshuenco project.

At the end of the fiscal year 2017, following an analysis during the last months, Enel Generación Chile determined to abandon the Neltume project; a decision justified mainly by the high-sustained competitiveness in the Chilean electricity market, which in November 2017 was ratified with the result of the last tender of Electric Distributors. Added to the above, there is the time associated with developing the alternative water discharge, considering a period of no less than 5 years, given the necessity to request and obtain a transfer of the current Water Right and commission a new study for environmental impact. The abandonment implied the recognition of a Th$ 21,975,641 loss, with the purpose of reducing to zero the net book value of the assets associated with the project (see Note 28).

Additionally, the Company also decided to abandon the Choshuenco project, mainly because the strong synergies considered with the Neltume hydroelectric project would not exist anymore and make it not viable. This decision involved recognizing a loss of Th$3,130,270, with the purpose of reducing the net book value of the assets associated with the project to zero (See Note 28)

9. As of August 31, 2016, the Company decided to withdraw from the water rights associated with the hydroelectric projects Bardón, Chillan 1, Chillan 2, Futaleufú, Hechún and Puelo. This decision was taken because of, among other aspects evaluated, the high annual maintenance cost of these unused water rights, lack of technical and economic feasibility and insufficient local community support. As a result, the Group wrote-off a total amount of ThCh$ 32,834,160 of property, plant and equipment and ThCh$ 2,549,926 of intangible assets, which represent 100% of the related costs previously capitalized.

10. As of December 31, 2016, the Group recognized an impairment loss of ThCh$ 6,577,946 associated with certain Non-Conventional Renewable Energy (“NCRE”) initiatives, such as wind, mini-hydro, biomass and solar projects. These initiatives deal with collection of natural resources data (wind speed, solar radiation, etc.) as well as engineering studies enabling the Company to perform and support technical and economical assessments in order to visualize their perspectives and decide on future steps. The results of the studies have not been entirely satisfactory, mainly due to the current conditions in the Chilean electricity market, as future viability of the NCRE projects is uncertain. As a result the Group recognized an impairment of 100% of the capitalized investments to date in NCRE projects

On the other hand, the Group decided to write off 100% of capitalized investment in two thermal projects that until now were held in its portfolio. These are the Tames 2 and Totoralillo projects, which were being developed within the framework of the public land concessions provided by the National Heritage Ministry in 2013. The amount of the write-off was ThCh$ 1,096,137 and arose as a result of the current conditions in the Chilean electricity market, lack of future viability of this type of technology (steam-coal) and high development costs, which make these projects unfeasible.

Additionally, at the end of fiscal year 2016, the Company recorded an account payable for Th$2,244,900, from penalties that it should pay for waiving the concessions related to these projects. During fiscal year 2017, the Ministry of National Assets and Enel Generación Chile, agreed to extinguish onerous concessions and not imposed any penalties.

Recovery of deferred tax assets will depend on whether sufficient tax profits will be obtained in the future. The Group believes that the future profit projections for its subsidiaries will allow these assets to be recovered.b)As of December 31, 2017, the Group does not have unrecognized deferred tax assets related to tax losses carry forward (see Note 3.o).

The Group has not recognized deferred tax liabilities for taxable temporary differences associated with investment in subsidiaries and joint ventures, as it is able to control the timing of the reversal of the temporary differences and considers that it is probable that such temporary differences will not reverse in the foreseeable future. The aggregate amount of taxable temporary differences associated with investments in subsidiaries and joint ventures for which deferred tax liabilities have not been recognized totaled ThCh$ 59,530,551 as of December 31, 2017 (ThCh$ 116,489,507 as of December 31, 2016).

Additionally, the Group has not recognized deferred tax assets for deductible temporary differences, associated with investment in subsidiaries and joint ventures, as it is able to control the timing of the reversal of the temporary differences and considers that it is probable that such temporary differences will not reverse in the foreseeable future, which as of December 31, 2017, totaled ThCh$ 238,424,357 (ThCh$ 385,427,246 as of December 31, 2016).

The Group companies are potentially subject to income tax audits by the tax authorities in Chile. 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

F-71

nature are often complex and can require several years to complete. Tax periods potentially subject to examination correspond to fiscal years 2014-2016.

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 Management estimates that the liabilities, if any, that may arise from such audits, would not significantly impact the Company’s future results.

The effects of deferred tax on the components of Other Comprehensive Income are as follows:

	For the year ended December 31, 2017			For the year ended December 31, 2016			For the year ended December 31, 2015

Law No. 20,780 was published in the Diario Oficial (the Official Gazette) on September 29, 2014, modifying the income tax and other tax systems. The law stipulates that, starting in 2017, the current income tax system will be replaced with two alternative tax systems: the attributed income system and the partially integrated system.

This Law gradually increases the rate of income tax on corporate income. Thus, it  are increased to 21% in 2014, to 22.5% in 2015, and 24% in 2016. From 2017 taxpayers choosing the attributed income system are subject to a rate of 25%, while companies choosing the partially integrated system aree subject to a rate of 25.5% in 2017 and 27% in 2018.

The Law also states that corporations will automatically be subject to the partially integrated system unless a future Special Shareholders’ Meeting agrees to select the attributed income system.

Law No. 20,899 was published on February 8, 2016, simplifying the income tax system. This law among its main modifications, imposes a partially integrated system as mandatory for corporations, cancelling previously available attributed income system option.

F-77

18. RISK MANAGEMENT POLICY

The Group’s companies are exposed to certain risks that are managed by systems that identify, measure, limit concentration of, and monitor these risks.

The main principles in the Group’s risk management policy include the following:

- Compliance with good corporate governance standards.

- Strict compliance with all the Group’s internal policies.

- Each business and corporate area determines:

i) The markets in which it can operate based on its knowledge and ability to ensure effective risk management.

ii) Criteria regarding counterparts.

iii) Authorized operators.

- Business and corporate areas establish their risk tolerance in a manner consistent with the defined strategy for each market in which they operate.

- All of the operations of the businesses and corporate areas are conducted within the limits approved for each case.

- Businesses, corporate areas, lines of business and companies design the risk management controls necessary to ensure that transactions in the markets are conducted in accordance with the Group policies, standards, and procedures.

18.1 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.

Depending on the Group’s estimates and on the objectives of the debt structure, hedging transactions are performed by entering into derivatives contracts that mitigate interest rate risk.

The financial debt structure of the Group detailed by fixed and/or hedged and floating interest rate on total net debt, net of hedging derivative instruments, is as follows:

Gross position

	Balance as of
	12-31-2017	12-31-2016
	%	%
Fixed interest rate	92%	92%

F-78

18.2 Exchange rate risk

Exchange rate risks principally involve the following transactions:

- Debt taken on by the Group’s companies that is denominated in a currency other than that in which its cash flows are indexed.

- Payments to be made for the acquisition of project-related materials in a currency other than that in which its cash flows are indexed.

- Revenues in Group companies directly linked to changes in currencies other than those of its cash flows.

In order to mitigate exchange rate 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 this 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. In addition, the policy seeks to refinance debt in the functional currency of each of the Group’s companies.

18.3 Commodities risk

The Group has a risk exposure to price changes in certain commodities, due basically to:

- Purchases of fuel used to generate electricity.

- Energy purchase/sale transactions that take place in local markets.

In order to reduce the risk in situations of extreme drought, the Company 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, in the case of regulated customers subject to long-term tender agreements, it determines indexation polynomials that help reduce exposure to commodity risk.

Considering the operating conditions faced by the power generation market in Chile, with drought and highly volatile commodity prices on international markets, the Company is constantly verifying the advisability of using hedging to lessen the impacts that these price swings have on its results.

As of December 31, 2017, the Group had swap hedges for 2.3 million MMBTU to be settled at January 2018.

As of December 31, 2016, the Group had swap hedges for 3 million barrels of Brent oil to be settle from January to November 2017 and 3.3 million MMTBU of Henry Hub gas swap to be settle from January to September 2017.

Depending on operating conditions, which are constantly being updated, these hedges may be modified or may cover other commodities.

Depending on operating conditions, which are constantly being updated, these hedges may be modified or may cover other commodities.

18.4 Liquidity risk

The Group’s liquidity risk management policy 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.

F-79

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 17, 19, and Appendix 4).

As of December 31, 2017 the Group has liquidity of cash and cash equivalent totaling ThCh$ 211,027,141 (ThCh$ 114,486,479 as of December 31, 2016) and unconditionally available lines of long-term credit totaling ThCh$ 199,271,103 (ThCh$ 342,827,047 as of December 31, 2016).

18.5 Credit risk

The Group closely monitors its credit risk.

Trade receivables:

The credit risk for receivables from the Group’s commercial activity has historically been very low, due to the short-term period of collections from customers, resulting in non-significant cumulative receivables amounts.

Energy service to customers with outstanding payments is suspended, and most contracts have termination clauses for payment default. The Company monitors its credit risk on an ongoing basis and measures its maximum exposure to payment default risk, which, as stated above, is very limited.

Financial assets, other than trade receivables:

Cash surpluses are invested in the highest-rated local and foreign financial entities (with risk rating equivalent to investment grade whenever possible) with thresholds established for each entity.

Banks having investment grade ratings from the three main international rating agencies (Moody's, S&P and Fitch) are considered in the investment selection process.

Investments may be backed with Chilean treasury bonds and/or with commercial paper issued by the highest rated banks; the latter are preferred, as they offer higher returns (always in line with current investment policies).

18.6Risk 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 in calculating the current VaR consists of the following:

- Financial debt.

- Hedge derivatives for debt, dividends and projects.

The VaR determined represents the potential variation in value of the portfolio of positions described above within 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:

- U.S. dollar Libor interest rate.

- 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 for the risk variables, using scenarios based on actual observations for 5 years of the same period (quarter).

The quarterly 95%-confidence VaR number is calculated as the 5% percentile of the potential quarterly variations in the fair value of the portfolio.

Given the aforementioned assumptions, the quarterly VaR of the positions discussed above corresponds to ThCh$ 66,890,686.

These values represent the potential increase of the Debt and Derivatives’ Portfolio, thus these Values At Risk are inherently related, among other factors, to the Portfolio’s value at each quarter’s end.

In accordance with this policy provisional interim dividend No. 61 was paid on January 27, 2017, and the remaining of the final dividend No. 62, amounting to Th$ 21.56050 per share, was distributed and paid in May 2017.

The shareholders at the Ordinary Shareholders’ Meeting held on April 25, 2017 approved the dividend policy for 2017.

• Reserves for Exchange differences on translation: These arise primarily from exchange differences relating to:

- Translation of the financial statements of our foreign operations from their functional currencies to our presentation currency (i.e. Chilean peso) (see Note 2.7.3);

- Translation of goodwill arising from the acquisition of foreign operations with a functional currency other than the Chilean peso (see Note 3.b).

• Cash flow hedges reserves: These represent the cumulative portion of gains and losses on hedging instruments deemed effective in cash flow hedges (see Notes 3.f.5 and 3.m).

• Remeasurement of available-for-sale financial assets: These represent variations in fair value, net of their effect on the available-for-sale investments (see Note 3.f.1).

(1) Reserve for corporate reorganization (Spin-Offs of companies) completed on March 1, 2016. Corresponds to the effects from the reorganization of the Company and the separation of the Chilean business into a new entity, Endesa Américas S.A. (see Note 5.2 and 23.1.1).

(2) Reserve for transition to IFRS. In accordance with Official Bulletin No. 456 from the CMF, included in this line item is the price-level restatement of paid-in capital from the date of transition to IFRS, January 1, 2004, to December 31, 2008. Also, it is included the foreign currency translation difference at the date of transition to IFRS.

Please note that, while the Company adopted the IFRS as its statutory accounting standards on January 1, 2009, the date of transition to that international standard used was January 1, 2004. This results from applying the exemption for that purpose in IFRS 1, “First Time Adoption”.

(3) Reserve from transactions with our subsidiaries. Corresponds to the effect of purchases of equity interests in subsidiaries that were accounted for as transactions between entities under common control.

(4) Other miscellaneous reserves from transactions made in prior years.

32. SUPPLEMENTAL DISAGGREGATED FINANCIAL INFORMATION

In the development of its activity, the organization of Enel Generación Chile was previously organized on the basis of the priority focus on its main business, consisting of the generation of electrical energy. Bearing in mind the differentiated information that is analyzed by the Administration for decision making, the information by segments had been presented following a geographical distribution by country:

- Chile.

- Argentina.   (discontinued)

- Perú. (discontinued)

- Colombia.   (discontinued)

However, since the corporate reorganization was carried out (see note 5.3.), And operations outside Chile are presented as discontinued operations in the consolidated financial statements, the Group no longer has operating segments as defined by IFRS 8 "Segments". The financial information currently provided to the Administration for decision making is the same included in the Group's consolidated financial statements. The Company, for comparative purposes, has chosen to voluntarily present supplementary disaggregated information of the net results and cash flows related to discontinued operations, on a geographical basis. The accounting policies used to determine this supplementary disaggregated financial information are the same as those used in the preparation of the Group's consolidated financial statements.

F-99

33.3 Litigation and arbitration

As of the date of these consolidated financial statements, the most relevant litigation involving the Group are as follows:

Pending lawsuits of the Company and Subsidiaries

1. Enel Generación Chile S.A.: In 2005, three lawsuits were filed against Enel Generación Chile S.A., the Chilean Treasury and the Chilean Water Authority (DGA, in its Spanish acronym), which are currently being treated as a single proceeding, requesting that DGA Resolution No. 134, which established non-consumptive water rights in favor of Enel Generación Chile S.A. to build the Neltume hydroelectric power plant project be declared null as a matter of public policy, with compensation for damages. Alternatively, the lawsuits request the compensation for damages for the losses allegedly sustained by the plaintiffs due to the loss of their status as riparian owners along Pirihueico Lake, as well as due to the devaluation of their properties. The defendants have rejected these allegations, contending that the DGA Resolution complies with all legal requirements, and that the exercise of this right does not cause any detriment to the plaintiffs, among other arguments. The sums involved in these suits are undetermined. This case was joined with two other cases: the first one is captioned “Arrieta v. the State and Others” in the 9th Civil Court, docket 15279-2005 and the second is captioned “Jordán v. the State and Others,” in the 10th Civil Court, docket 1608-2005. With regard to these cases, an injunction has been ordered against entering into any acts and contracts concerning Enel Generación Chile S.A.’s water rights related to the Neltume project. On September 25, 2014, the Court of Law issued an unfavorable ruling against Enel Generación Chile S.A. that in essence declared the right to use water established by DGA Resolution No. 134 illegal and orders its cancellation in the corresponding Water Rights Register of the correspondent Real Estate Registrar. Enel Generación Chile S.A. filed an appeal and cassation resources with the Santiago Court of Appeals, which are still pending. In parallel, on June 9, 2017 the Court of Appeals issued a complementary ruling rejecting the claims for compensation for damages on the ground that there were no damages affecting the defendants, Enel Generación Chile S.A. filed an appeal, which is still pending resolution. Notwithstanding the foregoing, on January 29, 2018, the Board of Enel Generación Chile SA unanimously agreed to stop and abandon the development of the hydroelectric projects of Neltume and Choshuenco for not being economically viable, so this judicial contingency is over. We must remember that the judicial plaintiffs had requested the declaration by a court that the water right is null.

2. GasAtacama Chile S.A.: On May 23, 2016 the Superintendency of Electricity and Fuels by means of ORD No. 5,705, filed charges against GasAtacama Chile S.A., for providing allegedly erroneous information to national centralizing operating agent CDEC-SING regarding the Minimum Technical (MT) and Average Time of Operation (TMO) parameters during the period from January 1, 2011 to October 29, 2015. GasAtacama Chile S.A. submitted its objections, which were rejected through notification by the Superintendency’s Resolution No. 014606 dated August 4, 2016, setting a fine for UTM 120,000. Disagreeing with the Superintendency’s resolution applying the fine in question, GasAtacama Chile S.A. filed an appeal for reinstatement filed before the Superintendency, which was rejected by the Superintendency through Resolution No. 15908, dated November 2, 2016, confirming the totality of the fine imposed. In opposition to the aforementioned resolution, GasAtacama Chile S.A. filed an illegality claim before the Court of Appeals of Santiago, recognizing provision for 25% of the fine. To date, the claim of illegality is pending resolution by the Court of Appeals of Santiago. The loss contingency rating on this issue is probable because although the contingency was assessed on the basis that the fine imposed does not meet the legal requirement, nevertheless we had to make provisions for 50% of the fine, for the single fact of the application of the fine by the State Regulator. The basis for recognizing half of the risk lies in the fact that we have sued the Superintendence of Electricity and Fuels, before the Courts of Justice, requesting the annulment of the fine because it has no legal basis.

33.4 Financial restrictions

A number of the Group’s loan agreements include the obligation to comply with certain financial covenants, which is normal for the contracts of this nature. There are also affirmative and negative ratios requiring the monitoring of these commitments. In addition, there are restrictions in the events-of-default clauses of the agreements which require compliance.

1) Cross Default

Some of the financial debt contracts of the Company contain cross default clauses. The domestic credit line agreement governed by Chilean law, which the Company signed in March 2016 for UF 2.8 million, stipulate that cross default arises only in the event of non-compliance by the borrower itself, with no reference made to its subsidiaries; i.e., the Company. In order to

F-100

accelerate payment of the debt in this credit line due to cross default originating from other debt, the amount overdue of a debt must exceed US$ 50 million, or the equivalent in other currencies, and other additional conditions must be met such as the expiry of grace periods. This credit line has not been drawn upon.

The Company’s international credit line governed by New York State law, which was signed in February 2016 expiring in February 2020, also makes no reference to its subsidiaries, thus, cross default is only triggered in the event of non-compliance by the borrower itself. For the repayment of debt to be accelerated under these credit lines due to cross default originated from other debt, the amount in default must exceed US$50 million or its equivalent in other currencies, and other additional conditions must be met, including the expiration of grace periods (if any), and a formal notice of intent to accelerate the debt repayment must have been served by creditors representing more than 50% of the amount owed or committed in the contract. As of December 31, 2017, these credit lines have not been drawn upon.

Regarding the bond issues of the Company registered with the United States Securities and Exchange Commission (the “SEC”), commonly called “Yankee bonds”, a cross default can be triggered by another debt of the Company or of any of its Chilean subsidiaries, for any amount overdue provided that the principal of the debt giving rise to the cross default exceeds US$ 30 million or its equivalent in other currencies. Debt acceleration due to cross default does not occur automatically but has to be demanded by the holders of at least 25% of the bonds of a certain series of Yankee bonds. In addition, events of bankruptcy or insolvency of foreign subsidiaries have no contractual effects on the Company’s Yankee bonds. The Company’s Yankee bonds mature in 2024, 2027, 2037 and 2097. Specifically for those maturing in 2024 (issued in April 2014), the threshold for triggering cross default increased to US$ 50 million or its equivalent in other currencies. As of December 31, 2017, the outstanding amount of Yankee bonds totals ThCh$ 438,757,209.

The bonds of the Company issued in Chile state that cross default can be triggered only by the default of the issuer in cases where the amount overdue exceeds US$50 million or its equivalent in other currencies. Debt acceleration requires the agreement of at least 50% of the bondholders of a certain series. As of December 31, 2017, the outstanding amount owed of domestic bonds totals ThCh$324,822,376.

2) 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.). Most of the Group’s financial covenants limit the level of indebtedness and evaluate the ability to generate cash flows in order to service the companies’ debts. Various companies are also required to certify these covenants periodically. The types of covenants and their respective limits vary according to the type of debt.

The Company bonds issued in Chile include the following financial covenants whose definitions and calculation formulas are established in the respective indentures:
