Report on review of interim consolidated financial statements

(English translation of a report originally issued in Korean)

The Shareholders and Board of Directors

Korea Electric Power Corporation

We have reviewed the accompanying interim consolidated financial statements of Korea Electric Power Corporation (the “Company”) and its subsidiaries (collectively referred to as the “Group”), which comprise the interim consolidated statement of financial position as of September 30, 2024, and the related interim consolidated statements of comprehensive income or loss for each of the three-month and nine-month periods ended September 30, 2024 and 2023, interim consolidated statements of changes in equity and interim consolidated statements of cash flows for each of the nine-month periods ended September 30, 2024 and 2023, and a summary material accounting policy information and other explanatory information.

Management’s responsibility for the interim consolidated financial statements

Management is responsible for the preparation and presentation of these interim consolidated financial statements in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (“KIFRS”) 1034 Interim Financial Reporting, and for such internal control as management determines is necessary to enable the preparation of interim financial statements that are free from material misstatement, whether due to fraud or error.

Auditor’s responsibility

Our responsibility is to express a conclusion on these interim consolidated financial statements based on our review. We conducted our review in accordance with the Review Standards for Quarterly and Semiannual Financial Statements established by the Securities and Futures Commission of the Republic of Korea. A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with Korean Standards on Auditing (“KSA”) and, consequently, does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe that the accompanying interim consolidated financial statements are not prepared, in all material respects, in accordance with KIFRS 1034 Interim Financial Reporting.

Other matters

We have audited the consolidated statement of financial position of the Group as of December 31, 2023, and the related consolidated statement of comprehensive income or loss, consolidated statement of changes in equity and consolidated statement of cash flows for the year then ended (not presented herein) in accordance with KSA, and our report dated March 11, 2024 expressed an unqualified opinion thereon. The accompanying consolidated statement of financial position as of December 31, 2023, presented for comparative purposes, is not different, in all material respects, from the above audited consolidated statement of financial position.

LOGO

November 14, 2024

This review report is effective as of November 14, 2024, the independent auditor’s review report date. Accordingly, certain material subsequent events or circumstances may have occurred during the period from the date of the independent auditor’s review report to the time this review report is used. Such events and circumstances could significantly affect the accompanying interim consolidated financial statements and may result in modifications to this review report.

KOREA ELECTRIC POWER CORPORATION AND ITS SUBSIDIARIES

Notes to the interim consolidated financial statements

September 30, 2024 and 2023 (unaudited)

1.	Reporting Entity (Description of the controlling company)

Korea Electric Power Corporation (“KEPCO”), the controlling company as defined in International Financial Reporting Standards as adopted by the Republic of Korea (“KIFRS”) 1110 Consolidated Financial Statements, was incorporated on January 1, 1982 in accordance with the Korea Electric Power Corporation Act (the “KEPCO Act”) to engage in the generation, transmission and distribution of electricity and development of electric power resources in the Republic of Korea. KEPCO’s stock was listed on the Korea Stock Exchange on August 10, 1989 and KEPCO listed its Depository Receipts (DR) on the New York Stock Exchange on October 27, 1994. KEPCO’s head office is located in Naju, Jeollanam-do.

As of September 30, 2024, KEPCO’s share capital amounts to W3,209,820 million and KEPCO’s shareholders are as follows:


	Number of shares		Percentage of ownership
The Government of the Republic of Korea		116,841,794		18.20	%
Korea Development Bank		211,235,264		32.90	%
Other (*)		313,887,019		48.90	%

		641,964,077		100.00	%

(*)	The number of shares held by foreign shareholders is 90,485,297 shares (14.10%) as of August 16, 2024, the most recent closing date of the shareholder list.

In accordance with the Restructuring Plan enacted on January 21, 1999 by the Ministry of Trade, Industry and Energy, KEPCO spun off its power generation divisions on April 2, 2001, resulting in the establishment of six power generation subsidiaries.

2.	Basis of Preparation

(1)

Statement of compliance

These interim consolidated financial statements have been prepared in accordance with KIFRS 1034 Interim Financial Reporting, enacted by the Act on External Audits of Stock Companies in the Republic of Korea. The accompanying interim consolidated financial statements have been translated into English from the Korean language financial statements. In the event of any differences in interpreting the financial statements or the independent auditor’s review report thereon, the Korean version, which is used for regulatory reporting purposes, shall prevail.

(2)

Basis of measurement

These consolidated financial statements have been prepared on the historical cost basis, except for the following material items in the consolidated statements of financial position:

•

financial instruments at fair value through profit or loss;

•

financial instruments at fair value through other comprehensive income or loss;

•

derivative financial instruments are measured at fair value; and

•

liabilities for defined benefit plans are recognized at the net of the total present value of defined benefit obligations less the fair value of plan assets.

(3)

Functional and presentation currency

These consolidated financial statements are presented in Korean Won (presented as “Won” or “KRW”), which is also the functional currency of KEPCO and most of the significant operating subsidiaries.

2.	Basis of Preparation, Continued

(4)

Use of estimates and judgments

The preparation of the consolidated financial statements in conformity with KIFRS requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates.

Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future periods affected.

Meanwhile, the Group considers climate-related risks resulting from climate change and the establishment of a global greenhouse gas reduction implementation system in its estimates and assumptions. Climate-related risks increase the uncertainty of the estimates and assumptions considered in various items of the financial statements, and the Group carefully monitors climate-related changes and developments, such as new climate-related legislation, even if it does not have a material impact on current measurements.

The followings are the key assumptions and other key sources of estimation uncertainty at the end of the reporting period, that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year.

(i)

Useful lives of property, plant and equipment, Intangible assets other than goodwill and estimations on provision for decommissioning costs.

The Group reviews the estimated useful lives of property, plant and equipment at the end of each annual reporting period. Management’s assumptions could affect the determination of estimated economic useful lives.

The Group records the fair value of estimated decommissioning costs as a liability in the period in which the Group incurs a legal obligation associated with the retirement of long-lived assets that result from acquisition, construction, development and/or normal use of the assets. The Group is required to record a liability for the dismantling (demolition) of nuclear power plants and disposal of spent fuel and low and intermediate radioactive wastes. The measurement of such liability is subject to change based on change in estimated cash flow, inflation rate, discount rate, and expected timing of decommissioning.

(ii)

Deferred tax

The Group recognizes deferred tax assets and liabilities based on the differences between the financial statement carrying amounts and the tax bases of assets and liabilities of each consolidated taxpaying entity. However, the amount of deferred tax assets may be different if the Group determines the estimated future taxable income is not sufficient to realize the deferred tax assets recognized.

(iii)

Valuations of financial instruments at fair values

The Group’s accounting policies and disclosures require the measurement of fair values, for both financial and non-financial assets and liabilities. The Group has established control framework with respect to the measurement of fair values. The valuation team regularly reviews significant unobservable inputs and valuation adjustments.

If third party information, such as broker quotes or pricing services, is used to measure fair values, then the valuation team assesses the evidence obtained from the third parties to support the conclusion that such valuations meet the requirements of KIFRS including the level in the fair value hierarchy in which such valuation techniques should be classified.

When measuring the fair value of an asset or a liability, the Group uses market observable data as far as possible. Fair values are categorized into different levels in a fair value hierarchy based on the inputs used in the valuation techniques as follows.

If the inputs used to measure the fair value of an asset or a liability might be categorized in different levels of the fair value hierarchy, then the fair value measurement is categorized in its entirety in the same level of the fair value hierarchy as the lowest level input that is significant to the entire measurement. The Group recognizes transfers between levels of the fair value hierarchy at the end of the reporting period during which the change has occurred.

Use of estimates and judgments, continued

(iv)

Defined employee benefit liabilities

The Group offers its employees 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. For actuarial valuations, certain inputs such as discount rates and future salary increases are estimated. Defined benefit plans contain significant uncertainties in estimations due to its long-term nature (refer to Note 25).

(v)

Unbilled revenue

Electricity delivered but neither metered nor billed is estimated at the reporting date based on the volume of electricity delivered which can vary significantly as a result of customer usage patterns, customer mix, meter reading schedules, weather, and etc. Unbilled revenue recognized as of September 30, 2024 and 2023 are W2,138,161 million and W 1,885,288 million, respectively.

(vi)

Construction contracts

The Group recognizes revenue over time using the cost-based input method which represents a faithful depiction of the Group’s progress towards complete satisfaction of providing the power plant construction, which has been identified as a single performance obligation. In applying the cost-based input method, it is necessary to use estimates and assumptions related to the Group’s efforts or inputs expected to be incurred. Costs incurred towards contract completion include costs associated with direct materials, labor, and other indirect costs related to contract performance. Judgment is required in estimating the costs expected to incur in completing the construction projects which involves estimating future materials, labor, contingencies and other related costs. Revenue is estimated based on the contractual amount; however, it can also be affected by uncertainties resulting from unexpected future events.

Changes in accounting policies

Changes in accounting standards effective from January 1, 2024 are as follows. The Group believes that these amendments have no significant impact on the Group’s interim consolidated financial statements. The Group has not early adopted any other standards, interpretations or amendments that have been issued but not yet effective.

Amendments to KIFRS 1007 and KIFRS 1107 - Supplier Finance Arrangements

The amendments clarify the characteristics of supplier finance arrangements and require additional disclosure of such arrangements. The disclosure requirements in the amendments are intended to assist users of financial statements in understanding the effects of supplier finance arrangements on an entity’s liabilities, cash flows and exposure to liquidity risk. The transition rules clarify that an entity is not required to provide the disclosures in any interim periods in the year of initial application of the amendments.

Amendments to KIFRS 1116 - Lease Liability in a Sale and Leaseback

The amendments specify the requirements that a seller-lessee uses in measuring the lease liability arising in a sale and leaseback transaction, to ensure the seller-lessee does not recognize any amount of the gain or loss that relates to the right of use it retains.

Amendments to KIFRS 1001 - Classification of Liabilities as Current or Non-current

The amendments to paragraphs 69 to 76 of KIFRS 1001 specify the requirements for classifying liabilities as current or non-current. The amendments clarify:

•

what is meant by a right to defer settlement;

•

that a right to defer must exist at the end of the reporting period;

•

that classification is unaffected by the likelihood that an entity will exercise its deferral right; and

•

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

In addition, a requirement has been introduced whereby an entity must disclose when a liability arising from a loan agreement is classified as non-current and the entity’s right to defer settlement is contingent on compliance with future covenants within twelve months.

3.	Material Accounting Policies

The accounting policies applied by the Group in these consolidated financial statements are the same as those applied by the Group in its consolidated financial statements as of and for the year ended December 31, 2023, except for the changes described in Note 2.(5).

4.	Segment, Geographic and Other Information

(1)

Segment determination and explanation of the measurements

The Group’s operating segments are its business components that generate discrete financial information that is reported to and regularly reviewed by chief operating decision makers of the Group including but not limited to the Chief Executive Officer, for the purpose of resource allocation and assessment of segment performance. The Group’s reportable segments are “Transmission and distribution”, “Electric power generation (Nuclear)”, “Electric power generation (Non-nuclear)”, “Plant maintenance & engineering service” and “Others”; others mainly represent the business Unit that manages the Group’s foreign operations.

Segment operating profit (loss) is determined in the same way that consolidated operating profit is determined under KIFRS without any adjustment for corporate allocations. The accounting policies used by each segment are consistent with the accounting policies used in the preparation of the consolidated financial statements. Segment assets and liabilities are determined based on separate financial statements of the entities instead of on a consolidated basis. There are various transactions between the reportable segments, including sales of property, plant and equipment and so on, that are conducted on an arm’s-length basis at market prices that would be applicable to an independent third party. For subsidiaries which are in a different segment from that of its immediate parent company, their carrying amount in separate financial statements is eliminated in the consolidating adjustments in the tables below. In addition, consolidation adjustments in the table below include adjustments of the amount of investment in associates and joint ventures from the cost basis amount reflected in segment assets to that determined using equity method in the consolidated financial statements.

Trade and other receivables are classified as financial assets at amortized cost and are measured using the effective interest rate method. No interest is accrued for trade receivables related to electricity for the duration between the billing date and the payment due dates. However, once trade receivables are overdue, the Group imposes a monthly interest rate of 1.5% on the overdue trade receivables. The Group holds deposits of three months’ expected electricity usage for customers requesting temporary usage and customers with delinquent payments.

	W	10,543,559			11,214,624

At the end of each reporting period, the Group assesses whether the credit to trade receivables is impaired. The Group recognizes loss allowances for trade receivables individually when there is any objective evidence that other receivables are impaired and significant and classifies the trade receivables that are not individually assessed as the trade receivables subject to be assessed on a collective basis. Also, the Group recognizes loss allowances based on an “expected credit loss” (ECL) model.

(*1)	The Group used initial cost as their fair value because there was not enough information to determine fair value, and the range of the estimated fair value is wide.

(*2)

The Group has estimated the fair value of Set Holding by using the income approach and has recognized the difference between its fair value and book value as gain or loss on valuation of financial assets at FVOCI in other comprehensive income or loss during the nine-month period ended September 30, 2024.

(*3)

The Group additionally acquired shares in the entity through conversion of investments performed in accordance with corporate rehabilitation procedures, and classified the investments in the entity as financial assets at fair value through other comprehensive income as the Group does not hold a significant influence over the entity until the corporate rehabilitation procedures are completed.

(*4)	During the nine-month period ended September 30, 2024, BDI Co., Ltd. was delisted as the Court dismissed the application for temporary injunction requiring the suspension of delisting decision and others.

(*5)

The entity is undergoing corporate rehabilitation procedures for the nine-month period ended September 30, 2024 and the Group cannot hold significant influence over the entity until the corporate rehabilitation procedures are completed. Therefore, investments in the entity were reclassified as financial assets at fair value through other comprehensive income.

(*6)	Equity securities, acquired through debt-for-equity swaps of electricity rate bonds and others, consist of 449 companies including Hwan Young Steel Co., Ltd.

Financial assets at fair value through other comprehensive income as of September 30, 2024 and December 31, 2023 are as follows, continued:

					W	625,418		502,443		502,443

(*1)	The Group used initial cost as their fair value because there was not enough information to determine fair value, and the range of the estimated fair value is wide.

(*2)	The Group has estimated the fair value of Set Holding by using the income approach and has recognized the difference between its fair value and book value as gain or loss on valuation of financial assets at FVOCI in other comprehensive income or loss during the year ended December 31, 2023.

(*3)

The Group acquired shares in the entity through conversion of investments performed in corporate rehabilitation procedures, and classified the investment in the entity as financial assets at fair value through other comprehensive income as the Group does not hold a significant influence over the entity until the corporate rehabilitation procedures are completed.

(*4)

Bankruptcy was declared during the year ended December 31, 2023. The Group cannot hold significant influence due to the appointment of a bankruptcy trustee, so investments in the entity were reclassified as financial assets at fair value through other comprehensive income for the year ended December 31, 2023. The liquidation process was completed for the nine-month period ended September 30, 2024.

(*5)	Equity securities, acquired through debt-for-equity swaps of electricity rate bonds and others, consist of 415 companies including Hwan Young Steel Co., Ltd.

The Group determined the fair value of investment property on the transition date based on valuations conducted by an independent valuation firm that is independent of the Group. The valuation firm has appropriate qualifications and experience in the valuation of real estate in the Republic of Korea, and the valuation was conducted using a comparison method, which is a method of obtaining economic value based on the marketability of the property. The fair values of the investment properties as of the reporting date were determined in consideration of the fluctuation on the publicly announced individual land price after the KIFRS transition date (January 1, 2010).

All of the Group’s investment properties are held under freehold interests.

The contracts with purchasers state that the disclosure of information related to UAE and Egypt Eldaba nuclear power plant construction projects such as rate of progress, unbilled construction, impairment losses, etc. is not allowed without consent from the purchasers. The purchasers did not agree to disclose such information. Accordingly, the Group did not disclose such information based on KIFRS 1115 129.2(2) as it is probable that the purchasers may file a lawsuit for breach of contract if the Group does so. Also, the Group reported to the audit committee that those items will not be disclosed in the notes to the consolidated financial statements.

Income Taxes

(1)

Income tax expense is calculated by adjusting adjustments recognized in the current period, changes in deferred tax assets and liabilities resulting from temporary differences, and income tax expense related to items recognized as other than profit or loss. The average effective tax rate for the nine-month period ended September 30, 2024 is 36.26% and the average effective tax rate for the nine-month period ended September 30, 2023 is not calculated due to income tax benefit.

(2)

Pillar Two Model Rules

Pillar Two Model Rules legislation has been enacted or substantively enacted in certain jurisdictions where the Group operates. According to the amended “Adjustment of International Taxes Act No. 19191”, the Group has adopted Pillar Two Model Rules legislation from fiscal year beginning on January 1, 2024. The Group is currently assessing the potential exposure arising from the Pillar Two legislation. The assessment currently carried out is based on the tax filing documents for the recent period and the financial information for 2023. Based on the assessment carried out so far, the Group has identified its potential exposure to Pillar Two income taxes on profits earned in Jordan, Laos and others where the expected Pillar Two effective tax rate is likely to be lower than 15%. Although the potential effect is expected to arise from the constituent entities (mainly operating subsidiaries) in these jurisdictions, the Group expects that the potential effect arising from the Pillar Two income taxes is not significant. The Group has applied the mandatory exception to recognizing and disclosing information about deferred tax assets and liabilities arising from Pillar Two income taxes.

Financial risk management

The Group is exposed to various risks related to its financial instruments, such as, market risk (currency risk, interest rate risk, price risk), and credit risk. The Group monitors and manages the financial risks relating to the operations of the Group through internal risk reports which analyze exposures by degree and magnitude of risks. The Group uses derivative financial instruments to hedge certain risk exposures. The Group’s overall financial risk management strategy remains consistent with the prior year.

(i)

Credit risk

Credit risk is the risk of finance loss to the Group if a customer or counterparty to a financial instrument fails to meet its contractual obligations, and arises primarily from the sales activities, securities and derivatives. In addition, credit risk exposure may exist within financial guarantees and unused line of credits. As these financial institutions the Group makes transactions with are reputable financial institutions, the credit risk from them is considered limited. The Group decides credit transaction limits based on evaluation of client’s credit, through information obtained from the credit bureau and disclosed financial position at committing contracts.

①

Credit risk management

Electricity sales, the main operations of the Group are the necessity for daily life and industrial activities of Korean nationals and have importance as one of the national key industries. The Group dominates the domestic market supplying electricity to customers. The Group is not exposed to significant credit risk as customers of the Group are diverse and are from various industries and areas. The Group uses publicly available information and its own internal data related to trade receivables, to rate its major customers and to measure the credit risk that a counter party will default on a contractual obligation. For the incurred but not recognized loss, it is measured considering overdue period.

②

Impairment and allowance account

In accordance with the Group policies, individual material financial assets are assessed on a regular basis, trade receivables that are assessed not to be impaired individually are, in addition, assessed for impairment on a collective basis. Value of the acquired collateral (including the confirmation of feasibility) and estimated collectable amounts are included in this assessment.

Allowance for bad debts assessed on a collective basis are recognized for (i) the group of assets which individually are not material and (ii) incurred but not recognized losses that are assessed using statistical methods, judgment and past experience.

To manage its foreign currency risk related to foreign currency denominated receivables and payables, the Group has a policy to enter into currency swap agreements. In addition, to manage its foreign currency risk related to foreign currency denominated expected sales transactions and purchase transactions, the Group enters into currency forward agreements.

There is an economic relationship between the hedged item and the hedging instrument as the terms of cross-currency swap agreement is consistent with the terms of expected transaction (repayment of foreign debt securities and others). The hedging ratio is 1:1 as the risk of cross-currency swap agreement matches the hedged item. As of September 30, 2024, the hedging instrument (cross-currency swap) hedges the risk of the hedged item (repayment of foreign debt securities and others).

②

Interest rate risk

The Group is exposed to interest rate risk due to its borrowing with floating interest rates. A 1%p increase or decrease is used when reporting interest rate risk internally to key management personnel and represents management’s assessment of the reasonably possible change in interest rates.

The Group’s borrowings and debt securities with floating interest rates as of September 30, 2024 and December 31, 2023 are as follows:


In millions of Won Type	September 30, 2024		December 31, 2023
Short-term borrowings	W	4,440,353		4,435,420
Long-term borrowings		9,388,364		7,766,588
Debt securities		315,310		305,602

	W	14,144,027		12,507,610

A sensitivity analysis on the Group’s borrowings and debt securities assuming a 1%p increase and decrease in interest rates for the nine-month period ended September 30, 2024 and for the year ended December 31, 2023 is as follows:


In millions of Won	September 30, 2024					December 31, 2023
Type	1%p Increase			1%p Decrease		1%p Increase			1%p Decrease
Increase (decrease) of profit before income tax	W	(106,080	)		106,080		(125,076	)		125,076
Increase (decrease) of shareholder’s equity (*)		(106,080	)		106,080		(125,076	)		125,076

(*)	The effect on the shareholder’s equity excluding the impact of income taxes.

The Group manages its interest rate risk by having a balanced portfolio of fixed and variable rate loans and borrowings. To manage this, the Group enters into interest rate swaps, in which it agrees to exchange, at specified intervals, the difference between fixed and variable rate interest amounts calculated by reference to an agreed-upon notional principal amount. The above analysis measures the interest rate risk before reflecting the hedge effect by related derivatives.

(iv)

Liquidity risk

The Group has established an appropriate liquidity risk management framework for the management of the Group’s short, medium and long-term funding and liquidity management requirements. The Group manages liquidity risk by continuously monitoring forecasted and actual cash flows, and by matching the maturity profiles of financial assets and liabilities.

In addition, the Group has established credit lines on its trade financing and bank overdrafts, and through payment guarantees it has received, it maintains an adequate credit (borrowing) line.

Fair value risk

The fair value of the Group’s actively-traded financial instruments (i.e., FVTPL, FVOCI, etc.) is based on the traded market-price as of the reporting period end. The fair value of the Group’s financial assets is the amount which the asset could be exchanged for or the amount a liability could be settled for.

The fair values of financial instruments where no active market exists or where quoted prices are not otherwise available are determined by using valuation techniques. Valuation techniques include using recent arm’s length market transactions between knowledgeable, willing parties, if available, reference to the current fair value of another instrument that is substantially the same, discounted cash flow analysis and option pricing models. If there is a valuation technique commonly used by market participants to price the instrument and that technique has been demonstrated to provide reliable estimates of prices obtained in actual market transactions, the Group uses that technique.

For trade receivables and payables, the Group considers the carrying value net of impairment as fair value.

Interest rates used for determining fair value

The interest rates used to discount estimated cash flows, when applicable, are based on the government yield curve at the reporting date plus an adequate credit spread.

The discount rates used for calculating fair value as of September 30, 2024 and December 31, 2023 are as follows:


Type	September 30, 2024		December 31, 2023
Derivatives		0.44% ~ 16.89%		0.93% ~ 10.36%
Borrowings and debt securities		0.75% ~ 5.84%		0.96% ~ 5.84%
Leases		0.00% ~ 17.30%		0.00% ~ 17.03%

(iii)

Fair value hierarchy

The following table provides an analysis of financial instruments that are measured subsequent to initial recognition at fair value, classified as Level 1, 2 or 3, based on the degree to which the fair value is observable.


Level 1:		Unadjusted quoted prices in active markets for identical assets or liabilities;

Level 2:		Inputs other than quoted prices that are observable for the asset or liability either directly or indirectly; and

Level 3:		Inputs that are not based on observable market data.

Fair values of financial instruments by hierarchy level as of September 30, 2024 and December 31, 2023 are as follows:

The fair value of financial assets traded in the market (including those measured at FVTPL and FVOCI) is measured at the closing bid price quoted at the end of the reporting period. Meanwhile, the fair value of unmarketable financial assets (including those measured at FVTPL and FVOCI) is calculated using the fair value measurement performed by external pricing service agents. In addition, the Group considered the major economic indicators and economic environment of the derivatives to be evaluated, and measured the fair value of the derivatives using a discounted cash flow model that reflects the Group’s credit risk.
