Independent Auditor’s Review Report

Based on a report originally issued in Korean

The Board of Directors and Shareholders

Korea Electric Power Corporation:

Report on Review of Consolidated interim Financial Statements

We have reviewed the accompanying consolidated interim financial statements of Korea Electric Power Corporation and its subsidiaries (the “Group”), which comprise the consolidated interim statements of financial position as of March 31, 2019, the related consolidated interim statements of comprehensive income (loss), consolidated interim statements of changes in equity and consolidated interim statements of cash flows for the three-month period ended March 31, 2019 and the notes to the accompanying consolidated interim financial statement, including a summary of significant accounting policies.

Management’s Responsibility for the Consolidated interim Financial Statements

Management is responsible for the preparation and fair presentation of these consolidated interim financial statements in accordance with Korean International Financial Reporting Standards (“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 Review Responsibility

Our responsibility is to issue a report on these consolidated interim 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 statements 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 auditing standards generally accepted in the Republic of Korea(KGAAS). Consequently, it 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 reviews, nothing has come to our attention that causes us to believe that the accompanying consolidated interim financial statements are not prepared, in all material respects, in accordance with KIFRS 1034 ‘Interim Financial Reporting’.

Other Matters

The consolidated interim statements of comprehensive income, consolidated interim statements of changes in equity and consolidated interim statements of cash flows for the three-month period ended March 31, 2018, prepared in accordance with KIFRS 1034 and presented for comparative purpose, have been reviewed by KPMG Samjong Accounting Corp. whose review report dated May 15, 2018 expressed an unqualified review conclusion.

Moreover, the consolidated statement of financial position as of December 31, 2018, and the related consolidated statement of comprehensive income, consolidated statement of changes in equity and consolidated statement of cash flows for the year then ended which have been audited by KPMG Samjong Accounting Corp., in accordance with KGAAS (not presented herein), whose report dated March 11, 2019 expressed an unqualified opinion. The accompanying consolidated statement of financial position as of December 31, 2018 presented for comparative purpose is not different, in all material respects, from the above audited consolidated statement of financial position.

May 15, 2019

This review report is effective as of May 15, 2019, the independent auditor’s review report date. Accordingly, certain material subsequent events or circumstances may have occurred during the period from the independent auditor’s review report date to the time this review report is used. Such events and circumstances could significantly affect the accompanying consolidated interim financial statements and may result in modification to this review report.

Notes to the Consolidated Interim Financial Statements

March 31, 2019

(Unaudited)

1. Reporting Entity (Description of the controlling company)

Korea Electric Power Corporation (“KEPCO”), the controlling company as defined in Korean International Financial Reporting Standards (“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 also provides power plant construction services. 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 March 31, 2019, KEPCO’s share capital amounts toW3,209,820 million and KEPCO’s shareholders are as follows:

	Number of shares		Percentage of ownership
Government of the Republic of Korea		116,841,794		18.20	%
Korea Development Bank		211,235,264		32.90	%
Others (*)		313,887,019		48.90	%
		641,964,077		100.00	%

(*) The number of shares held by foreign shareholders are 179,864,932 shares (28.02%) as of the most recent closing date of Register of Shareholders (February 7, 2019).

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 consolidated interim financial statements have been prepared in accordance with KIFRS 1034 ‘Interim Financial Reporting’ as part of the period covered by KEPCO and subsidiaries’ (the “Group”) KIFRS annual financial statements.

(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 assets at fair value through profit or loss

• financial assets at fair value through other comprehensive income or loss

• derivative financial instruments are measured at fair value

• 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 (“Won”), which is KEPCO’s functional currency and the currency of the primary economic environment in which the Group operates.

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.

The key assumptions concerning the future, 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 are as follows:

(i) Useful lives of property, plant and equipment, 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 does not realize estimated future taxable income during the carryforward periods.

(iii) Valuations of financial instruments at fair values

The Group’s accounting policies and disclosures require the measurement of fair values, for both financial andnon-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.

(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 26).

(v) Unbilled revenue

Energy delivered but not metered nor billed is estimated at the reporting date based on consumption statistics and selling price estimates. Determination of the unbilled revenues at the end of the reporting period is sensitive to the estimated consumptions and prices based on statistics. Unbilled revenue recognized as of March 31, 2019 and 2018 areW1,348,717 million andW1,344,125 million, respectively.

(vi) Construction contracts

For each performance obligation satisfied over time, the Group recognizes revenue over time by measuring the progress towards complete satisfaction of that performance obligation. The Group applies a single method of measuring progress for each performance obligation satisfied over time and applies that method consistently to similar performance obligations and in similar circumstances. Revenue and costs are recognized based on the progress towards complete satisfaction of a performance obligation utilizing the cost-based input method at the end of the reporting period. 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 in the future, costs incurred which are not related to the performance obligation, changes in the Group’s efforts or inputs due to change of the performance obligation, etc. Total revenue is measured based on an agreed contract price; however, it may fluctuate due to the variation of performance obligations. The measurement of revenue is affected by various uncertainties resulting from unexpected future events.

(5) Changes in accounting policies

(i) KIFRS 1116 ‘Leases’

KIFRS 1116 replaces existing leases guidance, including KIFRS 1017 ‘Lease’, KIFRS 2104 ‘Determining whether an Arrangement contains a Lease’, KIFRS 2015 ‘Operating Leases – Incentives’ and KIFRS 2027 ‘Evaluating the Substance of Transactions Involving the Legal Form of a Lease’. The standard sets out the principles for the recognition, measurement, presentation and disclosure of leases and requires lessees to account for most leases under a singleon-balance sheet model.

Lessor accounting under KIFRS 1116 is substantially unchanged from KIFRS 1017. Lessors will continue to classify leases as either operating or finance leases using similar principles as in KIFRS 1017.

The Group adopted KIFRS 1116 using the modified retrospective method of adoption with the date of initial application of 1 January 2019. Under this method, the standard is applied retrospectively with the cumulative effect of initially applying the standard recognized at the date of initial application. The Group elected to use the recognition exemptions for lease contracts that, at the commencement date, have a lease term of 12 months or less and do not contain a purchase option (‘short-term leases’), and lease contracts for which the underlying asset is of low value(‘low-value assets’).

(5) Changes in accounting policies, continued

Before adoption of KIFRS 1116, the Group, as a lessee, classified a lease contract as a finance lease if it transferred substantially all of the risks and rewards incidental to ownership of the leased asset to the Group; otherwise as an operating lease. Upon adoption of KIFRS 1116, the Group applied a single recognition and measurement approach for all leases, except for short-term leases and leases oflow-value assets. The standard provides specific transition requirements and practical expedients, which has been applied by the Group.

• Leases previously classified as finance leases

The Group did not change the initial carrying amounts of recognized assets and liabilities at the date of initial application for leases previously classified as finance leases (i.e., theright-of-use assets and lease liabilities equal the lease assets and liabilities recognized under KIFRS 1017). The requirements of KIFRS 1116 was applied to these leases from 1 January 2019.

• Leases previously accounted for as operating leases

The Group recognizedright-of-use assets and lease liabilities for those leases previously classified as operating leases, except for short-term leases and leases oflow-value assets. Theright-of-use assets were recognized based on the amount equal to the lease liabilities, adjusted for any related prepaid and accrued lease payments previously recognized. Lease liabilities were recognized based on the present value of the remaining lease payments, discounted using the incremental borrowing rate at the date of initial application.

The Group also applied the available practical expedients wherein it:

• Applied the short-term leases exemptions to leases with lease term that ends within 12 months at the date of initial application

• Excluded the initial direct costs from the measurement of theright-of-use asset at the date of initial application

• Used hindsight in determining the lease term where the contract contains options to extend or terminate the lease

(ii) Summary of new accounting policies

Set out below are the new accounting policies of the Group upon adoption of KIFRS 1116, which have been applied from the date of initial application:

• Right-of-use assets

The Group recognizesright-of-use assets at the commencement date of the lease.Right-of-use assets are measured at cost, less any accumulated depreciation and impairment losses, and adjusted for anyre-measurement of lease liabilities. The cost ofright-of-use assets includes the amount of lease liabilities recognized, initial direct costs incurred, and lease payments made at or before the commencement date less any lease incentives received. Unless the Group is reasonably certain to obtain ownership of the leased asset at the end of the lease term, the recognizedright-of-use assets are depreciated on a straight-line basis over the shorter of its estimated useful life and the lease term.Right-of-use assets are subject to impairment.

• Lease liabilities

At the commencement date of the lease, the Group recognizes lease liabilities measured at the present value of lease payments to be made over the lease term. The lease payments include fixed payments (includingin-substance fixed payments) less any lease incentives receivable, variable lease payments that depend on an index or a rate, and amounts expected to be paid under residual value guarantees. The lease payments also include the exercise price of a purchase option reasonably certain to be exercised by the Group and payments of penalties for terminating a lease, if the lease term reflects the Group exercising the option to terminate. The variable lease payments that do not depend on an index or a rate are recognized as expense in the period on which the event or condition that triggers the payment occurs.

(5) Changes in accounting policies, continued

In calculating the present value of lease payments, the Group uses the incremental borrowing rate at the lease commencement date if the interest rate implicit in the lease is not readily determinable. After the commencement date, the amount of lease liabilities is increased to reflect the accretion of interest and reduced for the lease payments made. In addition, the carrying amount of lease liabilities is remeasured if there is a modification, a change in the lease term, a change in thein-substance fixed lease payments or a change in the assessment to purchase the underlying asset.

• Short-term leases and leases oflow-value assets

The Group applies the short-term lease recognition exemption to its short-term leases of machinery and equipment (i.e., those leases that have a lease term of 12 months or less from the commencement date and do not contain a purchase option). It also applies the lease oflow-value assets recognition exemption to leases of office equipment that are considered of low value. Lease payments on short-term leases and leases oflow-value assets are recognized as expense on a straight-line basis over the lease term.

Book value and change in book value ofright-of-use assets and lease liabilities are described in Note 25.

(iii) Other changes in accounting standards effective from January 1, 2019 are as follows. The Group believes that these amendments have no significant impact on the Group’s consolidated interim financial statements

KIFRS 2123 : Uncertainty over Income Tax Treatment

The Interpretation addresses the accounting for income taxes when tax treatments involve uncertainty that affects the application of KIFRS 1012 Income Taxes. It does not apply to taxes or levies outside the scope of KIFRS 1012, nor does it specifically include requirements relating to interest and penalties associated with uncertain 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 (tax loss), tax bases, unused tax losses, unused tax credits and tax rates

• How an entity considers changes in facts and circumstances

An entity has to determine whether to consider each uncertain tax treatment separately or together with one or more other uncertain tax treatments. The approach that better predicts the resolution of the uncertainty needs to be followed.

Amendments to KIFRS 1109 : Financial Instruments

Under KIFRS 1109, a debt instrument can be measured at amortized cost or at fair value through other comprehensive income, provided that the contractual cash flows are ‘solely payments of principal and interest on the principal amount outstanding’ (the SPPI criterion) and the instrument is held within the appropriate business model for that classification. The amendments to KIFRS 1109 clarify that a financial asset passes the SPPI criterion regardless of an event or circumstance that causes the early termination of the contract and irrespective of which party pays or receives reasonable compensation for the early termination of the contract.

Amendments to KIFRS 1019 : Employee Benefits

The amendments to KIFRS 1019 address the accounting when a plan amendment, curtailment or settlement occurs during a reporting period. The amendments specify that when a plan amendment, curtailment or settlement occurs during the annual reporting period, an entity is required to determine the current service cost for the remainder of the period after the plan amendment, curtailment or settlement, using the actuarial assumptions used to remeasure the net defined benefit liability (asset) reflecting the benefits offered under the plan and the plan assets after that event. An entity is also required to determine the net interest for the remainder of the period after the plan amendment, curtailment or settlement using the net defined benefit liability (asset) reflecting the benefits offered under the plan and the plan assets after that event, and the discount rate used to remeasure that net defined benefit liability (asset).

Amendments to KIFRS 1028: Long-term interests in associates and joint ventures

The amendments clarify that an entity applies KIFRS 1109 to long-term interests in an associate or joint venture to which the equity method is not applied but that, in substance, form part of the net investment in the associate or joint venture (long-term interests). This clarification is relevant because it implies that the expected credit loss model in KIFRS 1109 applies to such long-term interests.

The amendments also clarified that, in applying KIFRS 1109, an entity does not take account of any losses of the associate or joint venture, or any impairment losses on the net investment, recognized as adjustments to the net investment in the associate or joint venture that arise from applying KIFRS 1028Investments in Associates and Joint Ventures.

Amendments to KIFRS 1103 Business Combinations

The amendments clarify that, when an entity obtains control of a business that is a joint operation, it applies the requirements for a business combination achieved in stages, including remeasuring previously held interests in the assets and liabilities of the joint operation at fair value. In doing so, the acquirer remeasures its entire previously held interest in the joint operation.

An entity applies those amendments to business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after January 1, 2019 with early application permitted.

Amendments to KIFRS 1111 Joint Arrangements

A party that participates in, but does not have joint control of, a joint operation might obtain joint control of the joint operation in which the activity of the joint operation constitutes a business as defined in KIFRS 1103. The amendments clarify that the previously held interests in that joint operation are not remeasured.

An entity applies those amendments to transactions in which it obtains joint control on or after the beginning of the first annual reporting period beginning on or after January 1, 2019 with early application permitted.

Amendments to KIFRS 1012 Income Taxes

The amendments clarify that the income tax consequences of dividends are linked more directly to past transactions or events that generated distributable profits than to distributions to owners. Therefore, an entity recognizes the income tax consequences of dividends in profit or loss, other comprehensive income or equity according to where it originally recognized those past transactions or events.

An entity applies the amendments for annual reporting periods beginning on or after January 1, 2019 with early application permitted. When the entity first applies those amendments, it applies them to the income tax consequences of dividends recognized on or after the beginning of the earliest comparative period.

Amendments to KIFRS 1023 Borrowing Costs

The amendments clarify that an entity treats as part of general borrowings any borrowing originally made to develop a qualifying asset when substantially all of the activities necessary to prepare that asset for its intended use or sale are complete.

The entity applies the amendments to borrowing costs incurred on or after the beginning of the annual reporting period in which the entity first applies those amendments. An entity applies those amendments for annual reporting periods beginning on or after January 1, 2019 with early application permitted.

3. Significant Accounting Policies

The significant accounting policies applied by the Group in preparation of its consolidated interim financial statements are included below. Except as described in note 2.(5), the accounting policies applied by the Group in these consolidated interim 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, 2018.

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 the Group’s the chief operating decision maker, 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 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 arms-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.

No interest is accrued for trade receivables related to electricity for the duration between the billing date and the payment due dates. But 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.

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 trade 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.

(5) Changes in the allowance for doubtful accounts for the three-month period ended March 31, 2019 and for the year ended December 31, 2018 are as follows:

As these financial institutions the Group makes transactions with are reputable financial institutions, the credit risk from them are 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.

(3) 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. While for disclosure purposes, the fair value of financial liabilities is estimated by discounting a financial instruments with similar contractual cash flows based on the effective interest method.

(i) Fair value and book value of financial assets and liabilities as of March 31, 2019 and December 31, 2018 are as follows:

(ii) 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 rate used for calculating fair value as of March 31, 2019 and December 31, 2018 are as follows:

Type	March 31, 2019			December 31, 2018
Derivatives		0.01% ~ 4.16	%		0.02% ~ 4.16	%
Borrowings and debt securities		0.51% ~ 4.75	%		0.51% ~ 5.14	%
Finance lease		1.72% ~ 10.83	%		3.50% ~ 10.83	%

(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 March 31, 2019 and December 31, 2018 are as follows:

(3) Fair value risk, continued

The fair value of financial assets (FVTPL and FVOCI) publicly traded is measured at the closing bid price quoted at the end of the reporting period. Meanwhile, the fair value of unquoted financial assets (FVTPL and FVOCI) is calculated using the valuation results from an external pricing service in which weighted average borrowing rates of interest of evaluated companies are used as a discount rate. The fair value of derivatives is measured using valuation model which is determined at the present value of estimated future cash flows discounted at current market interest rate.

Changes of financial assets and liabilities which are classified as level 3 for the three-month period ended March 31, 2019 and for the year ended December 31, 2018 are as follows:

The Group imports all of its uranium ore concentrates from sources outside Korea (including the United States, United Kingdom, Kazakhstan, France, Russia, South Africa, Canada and Australia) which are paid for with currencies other than Won, primarily in U.S. dollars. In order to ensure stable supply, the Group entered into long-term and medium-term contracts with various suppliers, and supplements such supplies with purchases of fuels on spot markets. The long-term and medium-term contract periods vary among contractors and the stages of fuel manufacturing process. Contract prices for processing of uranium are generally based on market prices. Contract periods for ore concentrates, conversion, enrichment and design and fabrication are as follows:

Type	Periods	Contracted quantity
Concentrate	2019 ~ 2030	40,330 Ton U3O8

50. Contingencies and Commitments

(1) Ongoing litigations and claims related with contingent liabilities and contingent assets as of March 31, 2019 and December 31, 2018 are as follows:

In millions of won	March 31, 2019				December 31, 2018
	Number of cases		Claim amount		Number of cases		Claim amount
As the defendant		596	W	631,469		570	W	673,882
As the plaintiff		189		776,506		174		793,491

As of March 31, 2019, among the litigations mentioned above, there are ongoing litigations of KHNP, a subsidiary of KEPCO, against KEPCO Engineering & Construction Company, Inc., a subsidiary of KEPCO, as aco-defendant (one case amounting toW62,744 million).

A group of plaintiffs (consisting of 2,167 individuals) filed a lawsuit against NSSC regarding NSSC’s approval on May 18, 2015 of extending the operation of Wolsong unit 1 nuclear power plant. The appeal was ongoing as of March 31, 2019. Also, Greenpeace and others filed an administrative litigation against NSSC requesting cancelation of the construction permit of Shin-Kori unit 5 and 6 in September 12, 2016 and lost the lawsuit in Feburary 14, 2019. They appealed the case in March 18, 2019. The Group joined these litigations as a stakeholder with the permission of the Court.

As of March 31, 2019, in connection with Shin-Hanul unit 3 & 4, the Group has received communications from a vendor for costs incurred for the preliminary work of the main equipment and associated compensation due to the discontinuation of the construction. The Group does not believe that it has a present obligation for this vendor, and that it is probable that the Group will prevail if a lawsuit is filed against the Group. In addition, the Group cannot reliably estimate the potential outflow related to the obligation as of March 31, 2019.

The long-term service contract between Gyeonggi Green Energy Co., Ltd. (Gyeonggi Green Energy) and its fuel cell supplier expired during the year ended December 31, 2018. Based on the agreement with the creditors of Gyeonggi Green Energy, as Gyeonggi Green Energy was unable to renew the fuel cell supply contract by December 31, 2018, the creditors have the right to request immediate repayment of the related borrowings from Gyeonggi Green Energy or to take over the all shares held by KHNP. Depending on the result of this negotiation, the schedule of repayment of borrowings of Gyeonggi Green Energy Co., Ltd. may be adjusted accordingly. As of March 31, 2019, Gyeonggi Green Energy Co., Ltd. is in negotiations to renew the contract.

The Group is the defendant against a number of claims. The following are potentially significant ongoing claims pertaining to the Group.

① Hyundai Engineering & Construction Co., Ltd.(“Hyundai E&C”), SK Engineering & Construction Co., Ltd. and GS Engineering & Construction Co., Ltd. filed a lawsuit for increase in contract bill against KHNP in September 2013, in relation to the design changes on the plant construction of Shin-Hanwool 1 & 2. KHNP has paid the claim amounts ofW176,847 million in full upon the first and second trial, and believes that the contingent liabilities related to the other pending lawsuits are not significant.

② In December 2013, the Supreme Court of Korea ruled that regular bonuses also fall under the category of ordinary wages on the condition that those bonuses are paid regularly and uniformly. Also, the Supreme Court ruled that employees are entitled to retroactively demand certain wages based on the new ordinary wages that include regular bonuses as additional wages. However, the request may be limited to the extent of the principle of good faith.

The Group believes that the possibility of economic outflow is probable on the ongoing and the expected lawsuit. For this reason, the Group recognizedW28,766 million of other provision in relation to the lawsuit as of March 31, 2019.

The litigation was filed in the International Chamber of Commerce International Court of Arbitration but the Group has not recognized any provision because the probability of economic benefit outflow is remote and the related amount cannot be reliably estimated.

④ In connection with the electric power IT modernization project in Kerala, India, Enzen, a subcontractor, filed an arbitration against the Group to the Indian Council of Arbitration due to disagreements in the contract, but the Group has not recognized any losses because the probability of economic benefit outflow is remote and the related amount cannot be reasonably estimated.
