Independent Auditor’s Report

(English Translation of a Report Originally Issued in Korean)

To the Board of Directors and Shareholders of

KT Corporation

Opinion

We have audited the accompanying consolidated financial statements of KT Corporation and its subsidiaries (collectively referred to as the “Group”), which comprise the consolidated statements of financial position as at December 31, 2019 and 2018, and the consolidated statements of profit or loss, consolidated statements of comprehensive income, consolidated statements of changes in equity and consolidated statements of cash flows for the years then ended, and notes to the consolidated financial statements, including a summary of significant accounting policies.

In our opinion, the accompanying consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Group as at December 31, 2019 and 2018, and its consolidated financial performance and its consolidated cash flows for the years then ended in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (Korean IFRS).

Basis for Opinion

We conducted our audits in accordance with Korean Standards on Auditing. Our responsibilities under those standards are further described in the Auditor’s Responsibilities for the Audit of the Consolidated Financial Statements section of our report. We are independent of the Group in accordance with the ethical requirements of the Republic of Korea that are relevant to our audit of the consolidated financial statements and we have fulfilled our other ethical responsibilities in accordance with the ethical requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Key Audit Matters

Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the consolidated financial statements of the current period. These matters were addressed in the context of our audit of the consolidated financial statements as a whole, and informing our opinion thereon, and we do not provide a separate opinion on these matters.

(1) Cash-Generating Unit Impairment Assessment

As described in Note 2.16 in the consolidated financial statements, the Group assesses whether indicators of impairment on assets exist. This assessment is completed in accordance with Korean IFRS 1036. When an impairment indicator exists, then management performs an impairment test. Given that there is a significant difference between the market value and the total net assets of KT Corporation (“the Controlling Company”) as of December 31, 2019, the Group determined that indicators of impairment on the cash-generating units (“the CGUs”) in wire, wireless and corporate business CGUs in the Parent Company existed as at December 31, 2019.

1

Management completed an impairment test, and no impairment loss was recognized as the recoverable amount of each of the CGUs exceeds their respective carrying amounts.

To determine the recoverable amounts of the CGUs, the Group estimated future cash flows which reflected forecast information such as the number of users for communication services, average profit per user (“ARPU”), and other assumptions. Another critical assumption was the determination of a discount rate to apply to these forecasted future cash flows. Significant judgment is used by management in determining these key assumptions.

The carrying amounts of assets allocated to each of the CGUs are material in the financial statements. Management’s assumptions have a significant impact in determining the recoverable amounts, and an enterprise valuation requires a high degree of judgement, effort and specialized knowledge of management. Therefore, we determined that the impairment assessment of assets allocated to each of the aforementioned CGUs as a key audit matter.

We have performed the following audit procedures to address the above key audit matter:

• We obtained an understanding of the Group’s procedures for asset impairment assessment and evaluated relevant internal controls.

• We obtained an understanding of the Group’s operations and assessed their determination of the different CGUs.

• We evaluated the qualification and independence of professionals used by management to estimate the recoverable amounts.

• We evaluated the reasonableness of key assumptions used by management to estimate the recoverable amounts.

• We assessed the reasonableness of the revenue growth rates, operating margin and forecasts of investing activities of these CGUs and compared those amounts with historical results and current market conditions.

• We evaluated the appropriateness of valuation models used by management to estimate the recoverable amounts.

• We evaluated the results of a sensitivity analysis on the discount rate performed by management to assess the impact of changes in key assumptions on the impairment assessment.

Other Matter

Auditing standards and their application in practice vary among countries. The procedures and practices used in the Republic of Korea to audit such consolidated financial statements may differ from those generally accepted and applied in other countries.

Responsibilities of Management and Those Charged with Governance for the Consolidated Financial Statements

Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with Korean IFRS, and for such internal control as management determines is necessary to enable the preparation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

2

In preparing the consolidated financial statements, management is responsible for assessing the Group’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless management either intends to liquidate the Group or to cease operations.

Those charged with governance are responsible for overseeing the Group’s financial reporting process.

Auditor’s Responsibilities for the Audit of the Consolidated Financial Statements

Our objectives are to obtain reasonable assurance about whether the consolidated financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with Korean Standards on Auditing will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these consolidated financial statements.

As part of an audit in accordance with the Korean Standards on Auditing, we exercise professional judgment and maintain professional skepticism throughout the audit. We also:

• Identify and assess the risks of material misstatement of the consolidated financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.

• Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control.

• Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by management.

• Conclude on the appropriateness of management’s use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Group’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor’s report to the related disclosures in the consolidated financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor’s report. However, future events or conditions may cause the Group to cease to continue as a going concern.

• Evaluate the overall presentation, structure and content of the consolidated financial statements, including the disclosures, and whether the consolidated financial statements represent the underlying transactions and events in a manner that achieves fair presentation.

3

• Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the Group to express an opinion on the consolidated financial statements. We are responsible for the direction, supervision and performance of the Group audit. We remain solely responsible for our audit opinion.

We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit.

We also provide those charged with governance with a statement that we have complied with relevant ethical requirements regarding independence, and to communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards.

From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of the consolidated financial statements of the current period and are therefore the key audit matters. We describe these matters in our auditor’s report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.

The engagement partner on the audit resulting in this independent auditor’s report is Jin-Kyu Lee, Certified Public Accountant.

The Group maintains its accounting records in Korean won and prepares statutory financial statements in the Korean language (Hangul) in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (Korean IFRS). The accompanying consolidated financial statements have been condensed, restructured and translated into English from the Korean language financial statements.

The consolidated financial statements of the Group have been prepared in accordance with Korean IFRS. These are the standards, subsequent amendments and related interpretations issued by the International Accounting Standards Board (IASB) that have been adopted by the Republic of Korea.

The financial statements have been prepared on a historical cost basis, except for the following:

• Certain financial assets and liabilities (including derivative instruments), certain classes of property and equipment and investment property – measured at fair value

• Assetsheld-for-sale – measured at fair value less costs to sell

• Defined benefit pension plans – plan assets measured at fair value

The preparation of the consolidated financial statements requires the use of critical accounting estimates. Management also needs to exercise judgement in applying the Group’s accounting policies. The areas involving a higher degree of judgment or complexity, or areas where assumptions and estimates are significant to the consolidated financial statements are disclosed in Note 3.

2.2 Changes in Accounting Policy and Disclosures

(1) New and amended standards adopted by the Group

The Group has applied the following standards and amendments for the first time for their annual reporting period commencing January 1, 2019.

Notes to the Consolidated Financial Statements

December 31, 2019 and 2018

• Enactment of Korean IFRS 1116Leases

Under Korean IFRS 1116, with implementation of a single lease model, lessee is required to recognize assets and liabilities for all lease which lease term is over 12 months and underlying assets are not low value assets. A lessee is required to recognize aright-of-use asset and a lease liability representing its obligation to make lease payments.

With implementation of Korean IFRS 1116Lease, the Group has changed accounting policy. The Group has adopted Korean IFRS 1116 retrospectively, as permitted under the specific transitional provisions in the standard, and recognized the cumulative impact of initially applying the standard as at January 1, 2019, the date of initial application. The Group has not restated comparatives for the 2018 reporting period. The impact of the adoption of the leasing standard and the new accounting policies are disclosed in Note 42.

• Korean IFRS 1109Financial Instruments – Prepayment Features with Negative Compensation

The narrow-scope amendments made to Korean IFRS 1109Financial Instruments enable entities to measure certain prepayable financial assets with negative compensation at amortized cost. When a modification of a financial liability measured at amortized cost that does not result in the derecognition, a modification gain or loss shall be recognized in profit or loss. The amendment does not have a significant impact on the financial statements.

• Amendments to Korean IFRS 1019Employee Benefits – Amendment, Curtailment or Settlement of the Plan

The amendments require that an entity shall calculate current service cost and net interest for the remainder of the reporting period after a plan amendment, curtailment or settlement based on updated actuarial assumptions from the date of the change. The amendments also require that a reduction in a surplus must be recognized in profit or loss even if that surplus was not previously recognized because of the impact of the asset ceiling. The amendment does not have a significant impact on the financial statements.

• Amendments to Korean IFRS 1028Investments in Associates and Joint Ventures – Long-term Interests in Associates and Joint Ventures

The amendments clarify that an entity shall apply Korean IFRS 1109 to financial instruments in an associate or joint venture to which the equity method is not applied. These include long-term interests that, in substance, form part of the entity’s net investment in an associate or joint venture. The amendment does not have a significant impact on the financial statements.

Notes to the Consolidated Financial Statements

December 31, 2019 and 2018

• Enactment to Interpretation of Korean IFRS 2123Uncertainty over Income Tax Treatments

The interpretation explains how to recognize and measure deferred and current income tax assets and liabilities where there is uncertainty over a tax treatment, and includes guidance on how to determine whether each uncertain tax treatment is considered separately or together. It also presents examples of circumstances where a judgement or estimate is required to be reassessed. The enactment does not have a significant impact on the financial statements.

• Annual Improvements to Korean IFRS 2015 – 2017 Cycle:

• Korean IFRS 1103Business Combination

The amendments clarify that when a party to a joint arrangement obtains control of a business that is a joint operation, and had rights to the assets and obligations for the liabilities relating to that joint operation immediately before the acquisition date, the transaction is a business combination achieved in stages. In such cases, the acquirer shall remeasure its entire previously held interest in the joint operation. The amendment does not have a significant impact on the financial statements.

• Korean IFRS 1111Joint Agreements

The amendments clarify that when 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. In such cases, previously held interests in the joint operation are notre-measured. The amendment does not have a significant impact on the financial statements.

• Amendments to Paragraph 57A of Korean IFRS 1012Income Tax

The amendment is applied to all the income tax consequences of dividends and requires an entity to recognize the income tax consequences of dividends in profit or loss, other comprehensive income or equity according to where the entity originally recognized those past transactions or events. The amendment does not have a significant impact on the financial statements.

• Korean IFRS 1023Borrowing Costs

The amendments clarify that if a specific borrowing remains outstanding after the related qualifying asset is ready for its intended use (or sale), it becomes part of general borrowings. The amendment does not have a significant impact on the financial statements.

(2) New standards and interpretations not yet adopted by the Group

There are no certain new accounting standard and interpretation that have been published that are not mandatory for annual reporting period commencing January 1, 2019 and have not been early adopted by the Group.

• Amendments to Korean IFRS 1001Presentation of Financial Statements and Korean IFRS 1008 Accounting policies, changes in accounting estimates and errors – Definition of Material

The amendments clarify the explanation of the definition of material and amended Korean IFRS 1001 and Korean IFRS 1008 in accordance with the clarified definitions. Materiality is assessed by reference to omission or misstatement of material information as well as effects of immaterial information, and to the nature of the users when determining the information to be disclosed by the Group. These amendments should be applied for annual periods beginning on or after January 1, 2020, and earlier application is permitted. The Group does not expect that these amendments have a significant impact on the financial statements.

• Amendments to Korean IFRS 1103Business Combination – Definition of a Business

To consider the integration of the required activities and assets as a business, the amended definition of a business requires an acquisition to include an input and a substantive process that together significantly contribute to the ability to create outputs and excludes economic benefits from the lower costs. An entity can apply an optional concentration test, in which substantially all of the fair value of gross assets acquired is concentrated in a single asset or a group of similar assets, and the assets acquired would not represent a business. These amendments should be applied for annual periods beginning on or after January 1, 2020, and earlier application is permitted. The Group does not expect that these amendments have a significant impact on the financial statements.

• Agenda Resolution of the International Accounting Standards Commission – Lease Period

The International Accounting Standards Commission (IFRS IC) announced on December 16, 2019 that all economic disadvantages resulting from the termination of a lease are taken into account when determining the enforceable period for ‘the useful life of lease term and lease asset improvement rights’. The Group is analyzing the effect of changes in accounting policies on the financial statements for enforceable periods in accordance with the decision and will reflect the effect in the financial statements after the analysis is completed.

2.3 Consolidation

The Group has prepared the consolidated financial statements in accordance with Korean IFRS 1110Consolidated Financial Statements.

(a) Subsidiaries

Subsidiaries are all entities (including special purpose entities (“SPEs”)) over which the Group has control. The Group controls an entity when the Group is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power to direct the activities of the entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Group. They are deconsolidated from the date that control ceases.

The acquisition method of accounting is used to account for business combinations by the Group. The consideration transferred is measured at the fair values of the assets transferred, and identifiable assets acquired, and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date. The Group recognizes anynon-controlling interest in the acquired entity on anacquisition-by-acquisition basis either at fair value or at thenon-controlling interest’s proportionate share of the acquired entity’s net identifiable assets. All othernon-controlling interests are measured at fair values, unless otherwise required by other standards. Acquisition-related costs are expensed as incurred.

The excess of consideration transferred, amount of anynon-controlling interest in the acquired entity and acquisition-date fair value of any previous equity interest in the acquired entity over the fair value of the net identifiable assets acquired is recoded as goodwill. If those amounts are less than the fair value of the net identifiable assets of the business acquired, the difference is recognized directly in the profit or loss as a bargain purchase.

Intercompany transactions, balances and unrealized gains on transactions between group companies are eliminated. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the transferred asset. Accounting policies of subsidiaries have been changed where necessary to ensure consistency with the policies adopted by the Group.

(b) Changes in ownership interests in subsidiaries without change of control

Any difference between the amount of the adjustment tonon-controlling interest that do not result in a loss of control and any consideration paid or received is recognized in a separate reserve within equity attributable to owners of the Controlling Group.

(c) Disposal of subsidiaries

When the Group ceases to consolidate for a subsidiary because of a loss of control, any retained interest in the subsidiary is remeasured to its fair value with the change in carrying amount recognized in profit or loss.

23

KT Corporation and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2019 and 2018

(d) Associates

Associates are entities over which the Group has significant influence but does not possess control or joint control. Investments in associates are accounted for using the equity method of accounting, after initially being recognized at cost. Unrealized gains on transactions between the Group and its associates are eliminated to the extent of the Group’s interest in the associates. If the Group’s share of losses of an associate equals or exceeds its interest in the associate (including long-term interests that, in substance, form part of the Group’s net investment in the associate), the Group discontinues recognizing its share of further losses. After the Group’s interest is reduced to zero, additional losses are provided for, and a liability is recognized, only to the extent that the Group has incurred legal or constructive obligations or made payments on behalf of the associate. If there is an objective evidence of impairment for the investment in the associate, the Group recognizes the difference between the recoverable amount of the associate and its book amount as impairment loss. If an associate uses accounting policies other than those of the Group for transactions and events in similar circumstances, if necessary, adjustments shall be made to make the associate’s accounting policies conform to those of the Group when the associate’s financial statements are used by the Group in applying the equity method.

(e) Joint arrangement

A joint arrangement, wherein two or more parties have joint control, is classified as either a joint operation or a joint venture. A joint operator recognizes its direct right to the assets, liabilities, revenues and expenses of joint operations and its share of any jointly held or incurred assets, liabilities, revenues and expenses. A joint venture has rights to the net assets relating to the joint venture and accounts for that investment using the equity method.

2.4 Segment Reporting

Information of each operating segment is reported in a manner consistent with the business segment reporting provided to the chief operating decision-maker (Note 36). The chief operating decision-maker is responsible for allocating resources and assessing performance of the operating segments.

2.5 Foreign Currency Translation

(a) Functional and presentation currency

Items included in the financial statements of each of the Group’s entities are measured using the currency of the primary economic environment in which each entity operates (the “functional currency”). The consolidated financial statements are presented in Korean won, which is the Parent Company’s functional and presentation currency.

24

KT Corporation and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2019 and 2018

(b) Transactions and balances

Foreign currency transactions are translated into the functional currency using the exchange rates at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation of monetary assets and liabilities denominated in foreign currencies at year end exchange rates are generally recognized in profit or loss. They are deferred in other comprehensive income if they relate to qualifying cash flow hedges and qualifying effective portion of net investment hedges, or are attributable to monetary part of the net investment in a foreign operation.

Foreign exchange gains and losses that relate to borrowings are presented in the statement of profit or loss, within finance costs. All other foreign exchange gains and losses are presented in the statement of profit or loss within ‘other income or other expenses’.

Non-monetary items that are measured at fair value in a foreign currency are translated using the exchange rates at the date when the fair value was determined. Translation differences on assets and liabilities carried at fair value are reported as part of the fair value gain or loss. For example, translation differences onnon-monetary assets and liabilities such as equities held at fair value through profit or loss are recognized in profit or loss as part of the fair value gain or loss and translation differences onnon-monetary assets such as equities classified asavailable-for-sale financial assets are recognized in other comprehensive income.

2.6 Financial Assets

(a) Classification

The Group classifies its financial assets in the following measurement categories:

• those to be measured at fair value through profit or loss

• those to be measured at fair value through other comprehensive income

• those to be measured at amortized cost

The classification depends on the Group’s business model for managing the financial assets and the contractual terms of the cash flows.

For financial assets measured at fair value, gains and losses will either be recorded in profit or loss or other comprehensive income. For investments in debt instruments, this will depend on the business model in which the investment is held. The Group reclassifies debt investments when, and only when its business model for managing those assets changes.

For investments in equity instruments that are not held for trading, this will depend on whether the Group has made an irrevocable election at the time of initial recognition to account for the equity investment at fair value through other comprehensive income. Changes in fair value of the investments in equity instruments that are not accounted for as other comprehensive income are recognized in profit or loss.

25

KT Corporation and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2019 and 2018

(b) Measurement

At initial recognition, the Group measures a financial asset at its fair value plus, in the case of a financial asset not at fair value through profit or loss, transaction costs that are directly attributable to the acquisition of the financial asset. Transaction costs of financial assets carried at fair value through profit or loss are expensed in profit or loss.

Hybrid (combined) contracts with embedded derivatives are considered in their entirety when determining whether their cash flows are solely payment of principal and interest.

A. Debt instruments

Subsequent measurement of debt instruments depends on the Group’s business model for managing the asset and the cash flow characteristics of the asset. The Group classifies its debt instruments into one of the following three measurement categories:

• Amortized cost: Assets that are held for collection of contractual cash flows where those cash flows represent solely payments of principal and interest are measured at amortized cost. A gain or loss on a debt investment that is subsequently measured at amortized cost and is not part of a hedging relationship is recognized in profit or loss when the asset is derecognized or impaired. Interest income from these financial assets is included in ‘finance income’ using the effective interest rate method.

• Fair value through other comprehensive income: Assets that are held for collection of contractual cash flows and for selling the financial assets, where the assets’ cash flows represent solely payments of principal and interest, are measured at fair value through other comprehensive income. Movements in the carrying amount are taken through other comprehensive income, except for the recognition of impairment loss (and reversal of impairment loss), interest income and foreign exchange gains and losses which are recognized in profit or loss. When the financial asset is derecognized, the cumulative gain or loss previously recognized in other comprehensive income is reclassified from equity to profit or loss. Interest income from these financial assets is included in ‘finance income’ using the effective interest rate method. Foreign exchange gains and losses are presented in ‘finance income or finance costs’ and impairment loss in ‘finance costs or operating expenses’.

• Fair value through profit or loss: Assets that do not meet the criteria for amortized cost or fair value through other comprehensive income are measured at fair value through profit or loss. A gain or loss on a debt investment that is subsequently measured at fair value through profit or loss and is not part of a hedging relationship is recognized in profit or loss and presented net in the statement of profit or loss within ‘finance income or finance costs’ in the period in which it arises.

B. Equity instruments

The Group subsequently measures all equity investments at fair value. Where the Group’s management has elected to present fair value gains and losses on equity investments in other comprehensive income, there is no subsequent reclassification of fair value gains and losses to profit or loss following the derecognition of the investment. Dividends from such investments continue to be recognized in profit or loss as ‘finance income’ when the Group’s right to receive payments is established.

26

KT Corporation and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2019 and 2018

Changes in the fair value of financial assets at fair value through profit or loss are recognized in ‘finance income or finance costs’ in the statement of profit or loss as applicable. Impairment loss (and reversal of impairment loss) on equity investments, measured at fair value through other comprehensive income, are not reported separately from other changes in fair value.

(c) Impairment

The Group assesses on a forward looking basis the expected credit losses associated with its debt instruments carried at amortized cost and fair value through other comprehensive income. The impairment methodology applied depends on whether there has been a significant increase in credit risk. For trade receivables and lease receivables, the Group applies the simplified approach, which requires expected lifetime credit losses to be recognized from initial recognition of the receivables.

(d) Recognition and derecognition

Regular way purchases and sales of financial assets are recognized or derecognized on trade-date, the date on which the Group commits to purchase or sell the asset. Financial assets are derecognized when the rights to receive cash flows from the financial assets have expired or have been transferred and the Group has transferred substantially all the risks and rewards of ownership.

If a transfer does not result in derecognition because the Group has retained substantially all the risks and rewards of ownership of the transferred asset, the Group continues to recognize the transferred asset in its entirety and recognizes a financial liability for the consideration received.

(e) Offsetting of financial instruments

Financial assets and liabilities are offset and the net amount reported in the statements of financial position where there is a legally enforceable right to offset the recognized amounts and there is an intention to settle on a net basis or realize the assets and settle the liability simultaneously. The legally enforceable right must not be contingent on future events and must be enforceable in the normal course of business and in the event of default, insolvency or bankruptcy of the Group or the counterparty.

December 31, 2019 and 2018

2.7 Derivative Instruments

Derivatives are initially recognized at fair value on the date a derivative contract is entered into and are subsequently remeasured to their fair value at the end of each reporting period. The accounting for subsequent changes in fair value depends on whether the derivative is designated as a hedging instrument, and if so, the nature of the item being hedged. The Group has hedge relationships and designates certain derivatives as:

• hedges of a particular risk associated with the cash flows of recognized assets and liabilities and highly probable forecast transactions (cash flow hedges)

At inception of the hedge relationship, the Group documents the economic relationship between hedging instruments and hedged items including whether changes in the cash flows of the hedging instruments are expected to offset changes in the cash flows of hedged items.

The fair values of derivative financial instruments designated in hedge relationships are disclosed in Note 39.

The full fair value of a hedging derivative is classified as anon-current asset or liability when the remaining maturity of the hedged item is more than 12 months; it is classified as a current asset or liability when the remaining maturity of the hedged item is less than 12 months. Anon-derivative financial asset and anon-derivative financial liability is classified as a current ornon-current based on its expected maturity and its settlement, respectively.

The effective portion of changes in fair value of derivatives that are designated and qualify as cash flow hedges is recognized in the cash flow hedge reserve within equity, and the ineffective portion is recognized in ‘finance income (costs)’.

Amounts of changes in fair value of effective hedging instruments accumulated in equity are recognized as ‘finance income (costs)’ for the periods when the corresponding transactions affect profit or loss.

When a hedging instrument expires, or is sold, terminated, exercised, or when a hedge no longer meets the criteria for hedge accounting, any accumulated cash flow hedge reserve at that time remains in equity until the forecast transaction occurs, resulting in the recognition of anon-financial asset such as inventory. When the forecast transaction is no longer expected to occur, the cash flow hedge reserve and deferred costs of hedging that were reported in equity are immediately reclassified to profit or loss.

2.8 Trade Receivables

Trade receivables are recognized initially at the amount of consideration that is unconditional, unless they contain significant financing components when they are recognized at fair value. Trade receivables are subsequently measured at amortized cost using the effective interest method, less loss allowance. See Note 6 for further information about the Group’s accounting for trade receivables and Note 2.6 (c) for a description of the Group’s impairment policies.

2.9 Inventories

Inventories are stated at the lower of cost and net realizable value. Cost is determined using the moving average method, except for inventoriesin-transit.

2.10 Non-Current Assets (or Disposal Group)Held-for-Sale

Non-current assets (or disposal group) are classified as assets held for sale when their carrying amount will be recovered principally through a sale transaction rather than through continued use and when a sale is considered highly probable. The assets are measured at the lower amount between their carrying amount and the fair value less selling costs.

2.11 Property and Equipment

Property and equipment are stated at historical cost less accumulated depreciation and accumulated impairment losses. Historical cost includes expenditures that is directly attributable to the acquisition of the items.

Depreciation of all property and equipment, except for land, is calculated using the straight-line method to allocate their cost, net of their residual values, over their estimated useful lives as follows:

		Useful Life
Buildings		5 – 40 years
Structures		5 – 40 years
Machinery and equipment (Telecommunications equipment and others)		2 – 40 years
Others	Vehicles	4 – 6 years
	Tools	4 – 6 years
	Office equipment	2 – 6 years

The depreciation method, residual values and useful lives of property and equipment are reviewed at the end of each reporting period and, if appropriate, accounted for as changes in accounting estimates.

2.12 Investment Property

Investment property is a property held to earn rentals or for capital appreciation. An investment property is measured initially at its cost. After recognition as an asset, investment property is carried at cost less accumulated depreciation and impairment losses. Investment property, except for land, is depreciated using the straight-line method over their useful lives from 10 to 40 years.

Notes to the Consolidated Financial Statements

December 31, 2019 and 2018

2.13 Intangible Assets

(a) Goodwill

Goodwill is measured as explained in Note 2.3 (a) and goodwill arising from acquisition of subsidiaries and business are included in intangible assets. Goodwill is tested annually for impairment and carried at cost less accumulated impairment losses. Gains and losses on the disposal of subsidiaries and business include the carrying amount of goodwill relating to the subsidiaries and business sold.

For the purpose of impairment testing, goodwill acquired in a business combination is allocated to each of the CGUs, or group of CGUs, that is expected to benefit from the synergies of the combination. Goodwill is monitored at the operating segment level.

Goodwill impairment reviews are undertaken annually or more frequently if events or changes in circumstances indicate a potential impairment. The carrying amount of goodwill is compared to the recoverable amount, which is the higher of value in use and the fair value less costs to sell. Any impairment is recognized immediately as an expense and is not subsequently reversed.

(b) Intangible assets excluding goodwill

Intangible assets, except for goodwill, are initially recognized at its historical cost, and carried at cost less accumulated amortization and accumulated impairment losses. Membership rights (condominium membership and golf membership) that have an indefinite useful life are not subject to amortization because there is no foreseeable limit to the period over which the assets are expected to be utilized. The Group amortizes intangible assets with a limited useful life using the straight-line method over the following periods:

	Useful Life
Development costs	5 – 6 years
Software	6 years
Industrial property rights	5 – 50 years
Frequency usage rights	5 – 10 years
Others 1	2 – 50 years

¹  Membership rights (condominium membership and golf membership) and broadcast license included in others are classified as intangible assets with indefinite useful life.

2.14 Borrowing Costs

General and specific borrowing costs that are directly attributable to the acquisition, construction or production of a qualifying asset are capitalized during the period of time that is required to complete and prepare the asset for its intended use or sale. Investment income earned on the temporary investment of specific borrowings pending their expenditure on qualifying assets is deducted from the borrowing costs eligible for capitalization. Other borrowing costs are expensed in the period in which they are incurred.

Notes to the Consolidated Financial Statements

December 31, 2019 and 2018

2.15 Government Grants

Grants from the government are recognized at their fair value where there is a reasonable assurance that the grant will be received and the Group will comply with all attached conditions. Government grants related to assets are presented in the statement of financial position by setting up the grant as deferred income that is recognized in profit or loss on a systematic basis over the useful life of the asset. Grants related to income are presented as a credit in the statement of profit or loss within ‘other income’.

2.16 Impairment ofNon-Financial Assets

Goodwill and intangible assets with indefinite useful life are tested annually for impairment at the end of each reporting period. If certain assets are deemed to be impaired, their recoverable amount is estimated in order to determine the impairment loss. The Company estimates the recoverable amount for each asset, and in cases when the recoverable amount cannot be estimated for an asset, the recoverable amount of the cash generating unit to which the asset belongs is estimated. Corporate assets are allocated to individual cash generating units on a reasonable and consistent basis and if they cannot be allocated to individual cash generating units, they are allocated to the smallest group of cash generating units on a reasonable and consistent basis. An impairment loss is recognized for the amount by which the asset’s carrying amount exceeds its recoverable amount (higher of its fair value less costs of disposal and value in use). Impairment loss onnon-financial assets other than goodwill are evaluated for reversal at the end of each reporting period.

2.17 Trade and Other Payables

These amounts represent liabilities for goods and services provided to the Group prior to the end of reporting period which are unpaid. Trade and other payables are presented as current liabilities, unless payment is not due within 12 months after the reporting period. They are recognized initially at their fair value and subsequently measured at amortized cost using the effective interest method.

2.18 Financial Liabilities

(a) Classification and measurement

The Group’s financial liabilities at fair value through profit or loss are financial instruments held for trading. A financial liability is held for trading if it is incurred principally for the purpose of repurchasing in the near term. Derivatives that are not designated as hedging instruments or derivatives separated from financial instruments containing embedded derivatives are also categorized as held for trading.

The Group classifiesnon-derivative financial liabilities, except for financial liabilities at fair value through profit or loss, financial guarantee contracts and financial liabilities that arise when a transfer of financial assets does not qualify for derecognition, as financial liabilities carried at amortized cost and present as ‘trade payables’, ‘borrowings’ and ‘other financial liabilities’ in the statement of financial position.

31

KT Corporation and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2019 and 2018

Preferred shares that require mandatory redemption at a particular date are classified as liabilities. Interest expenses on these preferred shares using the effective interest method are recognized in the statement of profit or loss as ‘finance costs’, together with interest expenses recognized from other financial liabilities.

(b) Derecognition

Financial liabilities are removed from the statement of financial position when it is extinguished; for example, when the obligation specified in the contract is discharged or cancelled or expired or when the terms of an existing financial liability are substantially modified. The difference between the carrying amount of a financial liability extinguished or transferred to another party and the consideration paid (including anynon-cash assets transferred or liabilities assumed) is recognized in profit or loss.

2.19 Financial Guarantee Contracts

Financial guarantee contracts are recognized as a financial liability at the time the guarantee is issued. The liability is initially measured at fair value, subsequently at the higher of following and recognized in the statement of financial position within ‘other financial liabilities’:

• the amount determined in accordance with the expected credit loss model under Korean IFRS 1109Financial Instruments

• the amount initially recognized less, where appropriate, the cumulative amount of income recognized in accordance with Korean IFRS 1115Revenue from Contracts with Customers

2.20 Employee Benefits

(a) Post-employment benefits

The Group operates both defined contribution and defined benefit pension plans.

A defined contribution plan is a pension plan under which the Group pays fixed contributions into a separate entity. The contributions are recognized as employee benefit expenses when an employee has rendered service.

A defined benefit plan is a pension plan that is not a defined contribution plan. Generally, post-employment benefits are payable after the completion of employment, and the benefit amount depended on the employee’s age, periods of service or salary levels. The liability recognized in the statement of financial position in respect of defined benefit pension plans is the present value of the defined benefit obligation at the end of the reporting period less the fair value of plan assets. The defined benefit obligation is calculated annually by independent actuaries using the projected unit credit method. The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows using interest rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be paid, and that have terms approximating to the terms of the related obligation. Remeasurement gains and losses arising from experience adjustments and changes in actuarial assumptions are recognized in the period in which they occur, directly in other comprehensive income.

32

KT Corporation and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2019 and 2018

Changes in the present value of the defined benefit obligation resulting from plan amendments or curtailments are recognized immediately in profit or loss as past service costs.

(b) Termination benefits

Termination benefits are payable when employment is terminated by the Group before the normal retirement date, or whenever an employee accepts voluntary redundancy in exchange for these benefits. The Group recognizes termination benefits at the earlier of the following dates: when the entity can no longer withdraw the offer of those benefits or when the entity recognizes costs for a restructuring.

(c) Long-term employee benefits

Certain entities within the Group provide long-term employee benefits that are entitled to employees with service period for ten years and above. The expected costs of these benefits are accrued over the period of employment using the same accounting methodology as used for defined benefit pension plans. The Group recognizes service cost, net interest on other long-term employee benefits and remeasurements as profit or loss for the year. These liabilities are valued annually by an independent qualified actuary.

2.21 Share-Based Payments

Equity-settled share-based payment is recognized at fair value of equity instruments granted, and employee benefit expense is recognized over the vesting period. At the end of each period, the Group revises its estimates of the number of options that are expected to vest based on thenon-market vesting and service conditions. It recognizes the impact of the revision to original estimates, if any, in profit or loss, with a corresponding adjustment to equity.

2.22 Provisions

Provisions for service warranties, recoveries, litigations and claims, and others are recognized when the Group presently hold legal or constructive obligation as a result of past events, and when it is probable that an outflow of resources will be required to settle the obligation and the amount can be reliably estimated. Provisions are measured at the present value of management’s best estimate of the expenditure required to settle the present obligation at the end of the reporting period, and the increase in the provision due to the passage of time is recognized as interest expense.

2.23 Leases

As explained in “Note 2.2 (1)” above, the Group has changed its accounting policy for leases. The impact of the new accounting policies is disclosed in Note 42.

As at December 31, 2018, leases of property and equipment where the Group, as lessee, had substantially all the risks and rewards of ownership were classified as finance leases. Finance leases were capitalized at the lease’s inception at the fair value of the leased property or, if lower, the present value of the minimum lease payments. The corresponding lease payments, net of finance charges, were included in other short-term or long-term payables. Each lease payment was allocated between the liability and finance cost. The finance cost was charged to profit or loss over the lease period in order as to produce a constant periodic rate of interest on the remaining balance of the liability for each period. Property and equipment acquired under finance leases were depreciated over the asset’s useful life, or over the shorter of the asset’s useful life and the lease term, if it was not reasonably certain that the Group will obtain ownership at the end of the lease term.

Leases in which a significant portion of the risks and rewards of ownership were not transferred to the Group as lessee were classified as operating leases. Payments made under operating leases (net of any incentives received from the lessor) were charged to profit or loss on a straight-line basis over the lease period.

(a) Lessee

The Group leases various repeater server rack, offices, track facilities, machinery and cars

Contracts may contain both lease andnon-lease components. The Group allocates the consideration in the contract to the lease andnon-lease components based on their relative stand-alone prices. However, for leases of real estate for which the Group is lessee, the Group applies the practical expedient which has elected not to separate lease andnon-lease components and instead accounts them as a single lease component.

Until the financial year of 2018, leases of property and equipment were classified as either finance or operating leases. Payments made under operating leases (net of any incentives received from the lessor) were charged to profit or loss on a straight-line basis over the period of the lease.

From January 1, 2019, leases are recognized as aright-of-use asset and a corresponding liability at the date at which the leased asset is available for use by the Group.

Assets and liabilities arising from a lease are initially measured on a present value basis. Lease liabilities include the net present value of the following lease payments:

• Fixed payments (includingin-substance fixed payments), less any lease incentives receivable

• Variable lease payment that are based on an index or a rate, initially measured using the index or rate as at the commencement date

Notes to the Consolidated Financial Statements

December 31, 2019 and 2018

• Amounts expected to be payable by the Group (the lessee) under residual value guarantees

• The exercise price of a purchase option if the Group (the lessee) is reasonably certain to exercise that option, and

• Payments of penalties for terminating the lease, if the lease term reflects the Group (the lessee) exercising that option

Lease liability measurement also include payments to be made in option periods if the lessee is reasonably certain in exercising an option to extend the lease.

The Group determines the lease term as thenon-cancellable period of a lease, together with both (a) periods covered by an option to extend the lease if the lessee is reasonably certain to exercise that option; and (b) periods covered by an option to terminate the lease if the lessee is reasonably certain not to exercise that option. When the lessee and the lessor each has the right to terminate the lease without permission from the other party, the Group should consider a termination penalty in determining the period for which the contract is enforceable.

The lease payments are discounted using the interest rate implicit in the lease. If that rate cannot be determined, the lessee’s incremental borrowing rate is used, which is the rate that the lessee would have to pay to borrow the funds necessary to obtain an asset of similar value in a similar economic environment with similar terms and conditions.

The Group is exposed to potential future increases in variable lease payments based on an index or rate, which are not included in the lease liability until they take effect. When adjustments to lease payments based on an index or rate take effect, the lease liability is reassessed and adjusted against theright-of-use asset.

Each lease payment is allocated between the liability and finance cost. The finance cost is charged to profit or loss over the lease period in order to produce a constant periodic rate of interest on the remaining balance of the liability for each period.

Right-of-use assets are measured at cost comprising the following:

• amount of the initial measurement of lease liability

• any lease payments made at or before the commencement date less any lease incentives received

• any initial direct costs (leasehold deposits)

• restoration costs, and

• present value discount on leasehold deposits

Notes to the Consolidated Financial Statements

December 31, 2019 and 2018

Theright-of-use asset is depreciated over the shorter of the asset’s useful life and the lease term on a straight-line basis. If the Group is reasonably certain to exercise a purchase option, theright-of-use asset is depreciated over the underlying asset’s useful life.

Payments associated with short-term leases and leases oflow-value assets are recognized on a straight-line basis as an expense in profit or loss. Short-term leases are leases with a lease term of 12 months or less, such as mechanical devices and cars.Low-value assets are comprised of tools, equipment, and others.

(b) Lessor

Lease income from operating leases where the Group is a lessor is recognized in income on a straight-line basis over the lease term. Initial direct costs incurred in obtaining an operating lease are added to the carrying amount of the underlying asset and recognized as expense over the lease term on the same basis as lease income. The respective leased assets are included in the statement of financial position based on their nature. As a result of adopting the new lease standard, the Group applied the accounting for assets held as a lessor.

2.24 Share Capital

The Group classifies ordinary shares as equity.

Where the Controlling Company purchases its own shares, the consideration paid, including any directly attributable incremental costs, is deducted from equity until the share are cancelled or reissued. When these treasury shares are reissued, any consideration received is included in equity attributable to the equity holders of the Controlling Company.

2.25 Revenue Recognition

(a) Identifying performance obligations

The Group identifies performance obligations with a customer such as providing telecommunication services, selling handsets and other. The revenue from handsets is recognized when a performance obligation is satisfied by transferring promised goods to customers, and the revenue from telecommunication services is recognized over the estimated contract periods of each services by transferring promised services to customers.

(b) Allocation the transaction price and revenue recognition

The Group allocates the transaction price to each performance obligation identified in the contract based on a relative stand-alone selling prices of the goods or services being provided to the customer. To allocate the transaction price to each performance obligation on a relative stand-alone price basis, the Group determines the stand-alone selling price at contract inception of the distinct good or service underlying each performance obligation in the contract and allocate the transaction price in proportion to those stand-alone selling price. The stand-alone selling price is the price at which the Group would sell a promised good or service separately to the customer. The best evidence of a stand-alone selling price is the observable price of a good or service when the Group sells that good or service separately in similar circumstances and to similar customers. The Group recognizes the allocated amount as contract assets or contract liabilities, and amortizes it through the remaining period which is adjusted in operating income.

Notes to the Consolidated Financial Statements

December 31, 2019 and 2018

(c) Incremental contract acquisition costs

The Group pays the commission fees when new customers subscribe for telecommunication services. The incremental contract acquisition costs are those commission fees that the Group incurs to acquire a contract with a customer that would not have been incurred if the contract had not been acquired.

The Group recognizes the incremental contract acquisition costs as an asset and amortizes it over the expected period of benefit. However, as a practical expedient, the Group may recognize the incremental contract acquisition costs as an expense when it is incurred if the amortization period of the asset is one year or less.

(d) Commission fees

Commission fees are recognized when it is probable that future economic benefits will flow to the entity and these benefits can be reliably measured. Revenues are measured at the fair value of the consideration received.

2.26 Current and Deferred Income Tax

The tax expense for the period consists of current and deferred tax. Current and deferred tax is recognized in profit or loss, except to the extent that it relates to items recognized in other comprehensive income or directly in equity. In this case, the tax is also recognized in other comprehensive income or directly in equity, respectively.

The tax expense is measured at the amount expected to be paid to the taxation authorities, using the tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period.

Management periodically evaluates tax policies that are applied in tax returns in which applicable tax regulation is subject to interpretation. The Group recognizes current income tax on the basis of the amount expected to be paid to the tax authorities.

Deferred income tax is provided in full, using the liability method, on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the consolidated financial statements. However, deferred income tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither accounting profit nor taxable profit or loss.

Deferred tax assets are recognized only if it is probable that future taxable amount will be available to utilize those temporary differences and losses.

The Group recognizes a deferred tax liability all taxable temporary differences associated with investments in subsidiaries, associates, and interests in joint arrangements, except to the extent that the Group is able to control the timing of the reversal of the temporary difference and it is probable that the temporary difference will not reverse in the foreseeable future. In addition, the Group recognizes a deferred tax asset for all deductible temporary differences arising from such investments to the extent that it is probable the temporary difference will reverse in the foreseeable future and taxable profit will be available against which the temporary difference can be utilized.

Notes to the Consolidated Financial Statements

December 31, 2019 and 2018

Deferred tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets and liabilities and when the deferred tax balances relate to the same taxation authority. Current tax assets and liabilities are offset when the Group has a legally enforceable right to offset and intends either to settle on a net basis, or to realize the assets and settle the liability simultaneously.

The Group adopts the consolidated corporate tax return and calculates income tax expenses and income tax liabilities of the Group based on systematic and reasonable methods.

2.27 Dividend

Dividend distribution to the Group’s shareholders is recognized as a liability in the financial statements in the period in which the dividends are approved by the Group’s shareholders.

2.28 Approval of Issuance of the Financial Statements

The consolidated financial statements of 2019 were approved for issuance by the Board of Directors on February 6, 2020 and are subject to change with the approval of shareholders at their Annual General Meeting.

3. Critical Accounting Estimates and Assumptions

The preparation of financial statements requires the Group to make estimates and assumptions concerning the future. Management also needs to exercise judgement in applying the Group’s accounting policies. Estimates and assumptions are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. As the resulting accounting estimates will, by definition, seldom equal the related actual results, it can contain a significant risk of causing a material adjustment.

The estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are discussed below. Additional information of significant judgement and assumptions of certain items are included in relevant notes.

3.1 Impairment of Non-Financial Assets (including Goodwill)

The Group determines the recoverable amount of a cash generating unit (CGU) based on fair value orvalue-in-use calculations assessnon-financial assets (including goodwill) for impairment (Note 13).

3.2 Income Taxes

The Group’s taxable income generated from these operations are subject to income taxes based on tax laws and interpretations of tax authorities in numerous jurisdictions. There are many transactions and calculations for which the ultimate tax determination is uncertain (Note 31).

If certain portion of the taxable income is not used for investments or increase in wages or dividends in accordance with the Tax System for Recirculation of Corporate Income, the Group is liable to pay additional income tax calculated based on the tax laws. Accordingly, the measurement of current and deferred income tax is affected by the tax effects from the new tax system. As the Group’s income tax is dependent on the investments, as well as wage and dividends increase, there is an uncertainty measuring the final tax effects.

3.3 Fair Value of Derivatives and Financial Instruments

The fair value of financial instruments that are not traded in an active market is determined by using valuation techniques. The Group uses its judgment to select a variety of methods and make assumptions that are mainly based on market conditions existing at the end of each reporting period (Note 39).

3.4 Impairment of Financial Assets

The provision for impairment for financial assets are based on assumptions about risk of default and expected loss rates. The Group uses judgement in making these assumptions and selecting the inputs to the impairment calculation based on the Group’s past history, existing market conditions as well as forward looking estimates at the end of each reporting period (Note 38).

3.5 Net Defined Benefit Liability

The present value of net defined benefit liability depends on a number of factors that are determined on an actuarial basis using a number of assumptions including the discount rate (Note 18).

3.6 Amortization of Contract Assets, Contract Liabilities and Contract Cost Assets

Contract assets, contract liabilities and contract cost assets recognized under the application of Korean IFRS 1115 are amortized over the expected periods of customer relationships. The estimate of the expected terms of customer relationship is based on the historical data. If management’s estimate changes, it may cause significant differences in the timing of revenue recognition and amounts recognized.

3.7 Provisions

As described in Note 17, the Group records provisions for litigation and assets retirement obligations as at the end of the reporting period. The provisions are estimated based on the factors such as the historical experiences.

3.8 Useful Lives of Property and Equipment and Investment Property

Property and equipment, intangible assets, and investment properties, excluding land, goodwill, condominium memberships, golf club memberships and broadcast license, are depreciated using the straight-line method over their useful lives. The estimated useful lives are determined based on expected usage of the assets and the estimates can be materially affected by technical changes and other factors. The Group will increase depreciation expenses if the useful lives are considered shorter than the previously estimated useful lives.

Notes to the Consolidated Financial Statements

December 31, 2019 and 2018

Principal actuarial assumptions used are as follows:

	December 31, 2019	December 31, 2018
Discount rate	1.66% ~3.00%	2.20% ~ 3.34%
Future salary increase	1.00% ~ 6.81%	1.39% ~ 7.82%

The sensitivity of the defined benefit obligations as at December 31, 2019, to changes in the principal assumptions is:

(in percentage, in millions of Korean won)	Effect on defined benefit obligation
	Changes in assumption		Increase in assumption		Decrease in assumption
Discount rate		0.5% point	W	(77,044)	W	83,574
Salary growth rate		0.5% point		76,010		(70,874)

A decrease in corporate bond yields will increase plan liabilities, although this will be partially offset by an increase in the value of the plans’ bond holdings.

The above sensitivity analyses are based on an assumption while holding all other assumptions constant. In practice, this is unlikely to occur, and changes in some of the assumptions may be correlated. The sensitivity of the defined benefit obligation to changes in principal actuarial assumptions is calculated using the projected unit credit method, the same method applied when calculating the defined benefit obligations recognized on the statement of financial position.

The Group actively monitors how the duration and the expected yield of the investments match the expected cash outflows arising from the pension obligations. Expected contributions to post-employment benefit plans for the year ending December 31, 2020, areW 353,284 million.

The expected maturity analysis of undiscounted pension benefits as at December 31, 2019, is as follows:

(in millions of Korean won)	Less than 1 year		Between 1-2 years		Between2-5 years		Over 5 years		Total
Pension benefits	W	241,380	W	273,477	W	834,025	W	3,849,346	W	5,198,228

The weighted average duration of the defined benefit obligations is 7.0 years.

19. Defined Contribution Plan

Recognized expense related to the defined contribution plan for the year ended December 31, 2019, isW 57,170 million (2018:W 48,210 million).

32. Earnings per Share

Basic earnings per share is calculated by dividing the profit from operations attributable to equity holders of the Group by the weighted average number of ordinary shares outstanding during the period, excluding ordinary shares purchased by the Group and held as treasury stock.

Basic earnings per share from operations for the years ended December 31, 2019 and 2018, is calculated as follows:

	2019		2018
Profit attributable to ordinary shares(in millions of Korean won)	W	619,182	W	688,464
Weighted average number of ordinary shares outstanding(in number of shares)		245,171,283		245,049,466
Basic earnings per share(in Korean won)	W	2,526	W	2,809

Diluted earnings per share from operations is calculated by adjusting the weighted average number of ordinary shares outstanding to assume conversion of all dilutive potential ordinary shares. The Group has dilutive potential ordinary shares from convertible redeemable preferred stocks, convertible bond and other share-based payments.

Diluted earnings per share from operations for the years ended December 31, 2019 and 2018, is calculated as follows:

	2019			2018
Profit attributable to ordinary shares(in millions of Korean won)	W	619,182		W	688,464
Adjusted net income attributable to ordinary shares(in millions of Korean won)		(157	)		—
Diluted profit attributable to ordinary shares(in millions of Korean won)	W	619,025		W	688,464
Number of dilutive potential ordinary shares outstanding(in number of shares)		70,267			1,163
Weighted average number of ordinary shares outstanding(in number of shares)		245,241,550			245,050,629
Diluted earnings per share(in Korean won)	W	2,524		W	2,809

Diluted earnings per share is earnings per outstanding of ordinary shares and dilutive potential ordinary shares. Diluted earnings per share is calculated by dividing adjusted profit for the year by the sum of the number of ordinary shares and dilutive potential ordinary shares.

38. Financial Risk Management

(1) Financial Risk Factors

The Group’s activities expose it to a variety of financial risks: market risk, credit risk and liquidity risk. The Group’s overall risk management program focuses on the unpredictability of financial markets and seeks to minimize potential adverse effects on the Group’s financial performance. The Group uses derivative financial instruments to hedge certain risk exposures such as cash flow risk.

The Group’s financial policy is set up in the long-term perspective and annually reported to the Board of Directors. The financial risk management is carried out by the Value Management Office, which identifies, evaluates and hedges financial risks. The treasury department in the Value Management Office considers various finance market conditions to estimate the effect from the market changes.

1) Market risk

The Group’s market risk management focuses on controlling the extent of exposure to the risk in order to minimize revenue volatility. Market risk is a risk that decreases value or profit of the Group’s portfolio due to changes in market interest rate, foreign exchange rate and other factors.

94

KT Corporation and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2019 and 2018

(i) Sensitivity analysis

Sensitivity analysis is performed for each type of market risk to which the Group is exposed. Reasonably possible changes in the relevant risk variable such as prevailing market interest rates, currency rates, equity prices or commodity prices are estimated and if the rate of change in the underlying risk variable is stable, the Group does not alter the chosen reasonably possible change in the risk variable. The reasonably possible change does not include remote or ‘worst case’ scenarios or ‘stress tests’.

(ii) Foreign exchange risk

The Group is exposed to foreign exchange risk arising from operating, investing and financing activities. Foreign exchange risk is managed within the range of the possible effect on the Group’s cash flows. Foreign exchange risk (i.e, foreign currency translation of overseas operating assets and liabilities) unaffecting the Group’s cash flows is not hedged but can be hedged at a particular situation.

As at December 31, 2019 and 2018, if the foreign exchange rate had strengthened/weakened by 10% with all other variables held constant, the effects on profit before income tax and equity would have been as follows:

(in millions of Korean won)	Fluctuation of foreign exchange rate			Income before tax1		Equity

(iii) Price risk

As at December 31, 2019 and 2018, the Group is exposed to equity securities price risk because the securities held by the Group are traded in active markets. If the market prices had increased /decreased by 10% with all other variables held constant, the effects on profit before income tax and equity would have been as follows:

(in millions of Korean won)	Fluctuation of price			Income before tax			Equity
2019.12.31		+ 10	%		W 23		W	697
		- 10	%		(23	)		(697	)
2018.12.31		+ 10	%		W 12		W	898
		- 10	%		(12	)		(898	)

Notes to the Consolidated Financial Statements

December 31, 2019 and 2018

The above analysis is based on the assumption that the equity index had increased/decreased by 10% with all other variables held constant and all the Group’s marketable equity instruments had moved according to the historical correlation with the index. Gain or loss on equity securities classified as financial assets at fair value through profit or loss and financial assets at fair value through other comprehensive income can increase or decrease equity.

(iv) Cash flow and fair value interest rate risk

The Group’s interest rate risk arises from liabilities in foreign currency such as foreign currency debentures. Debentures in foreign currency issued at variable rates expose the Group to cash flow interest rate risk which is partially offset by swap transactions. Debentures and borrowings issued at fixed rates expose the Group to fair value interest rate risk. The Group sets the policy and operates to minimize the uncertainty of the changes in interest rates and financial costs.

As at December 31, 2019 and 2018, if the market interest rate had increased/decreased by 100bp with other variables held constant, the effects on profit before income tax and equity would be as follows:

(in millions of Korean won)	Fluctuation of interest rate		Income before tax			Equity
2019.12.31		+ 100 bp		W425			W14,764
		- 100 bp		(482	)		(19,280	)
2018.12.31		+ 100 bp		W1,059			W9,689
		- 100 bp		(1,958	)		(10,237	)

The above analysis is a simple sensitivity analysis which assumes that all the variables other than market interest rates are held constant. Therefore, the analysis does not reflect any correlation between market interest rates and other variables, nor management’s decision to decrease the risk.

2) Credit risk

Credit risk is the risk of financial loss to the Group if a customer or counterparty to a financial instrument fails to meet its contractual obligations, and arises principally from the Group’s trade receivables from customers, debt securities and others.

• Risk management

Credit risk is managed on the Group basis with the purpose of minimizing financial loss. Credit risk arises from the normal transactions and investing activities, where clients or other party fails to discharge an obligation on contract conditions. To manage credit risk, the Group considers the counterparty’s credit based on the counterparty’s financial conditions, default history and other important factors.

Credit risk arises from cash and cash equivalents, derivative financial instruments and deposits with banks and financial institutions, as well as outstanding receivables. To minimize such risk, only the financial institutions with strong credit ratings are accepted.

Notes to the Consolidated Financial Statements

December 31, 2019 and 2018

The Group’s investments in debt instruments are considered to be low risk investments. The credit ratings of the investments are monitored for credit deterioration.

• Security

For some trade receivables, the Group may obtain security in the form of guarantees or letters of credit, etc. which can be called upon if the counterparty is in default under the terms of the agreement.

• Impairment of financial assets

The Group has four types of financial assets that are subject to the expected credit loss model:

• trade receivables for sales of goods and provision of services,

• contract assets relating to provision of services,

• debt investments carried at fair value through other comprehensive income, and

• other financial assets carried at amortized cost.

While cash equivalents are also subject to the impairment requirement, the identified impairment loss was immaterial.

The maximum exposure to credit risk of the Group’s financial instruments without considering value of collaterals as at December 31, 2019 and 2018, are as follows:

(in millions of Korean won)	December 31, 2019		December 31, 2018

(i) Trade and other receivables and contract assets

The Group applies a simplified method of recognizing the expected loss over its lifetime as a loss allowance for trade receivables and other receivables and contact assets.

The Group measures the expected credit loss by considering the future irrecoverability rate of the remaining balance of trade receivables and other receivables at the end of the reporting period. Each trade receivables and other receivables are classified considering the credit risk characteristics and overdue periods in order to measure expected credit loss. The expected credit loss rate calculation is based on historical payment and credit loss information in relation to revenue for 36 months period up to December 31, 2019.

(ii) Cash equivalents (except for cash on hand)

The Group is also exposed to credit risk in relation to financial assets that are measured at fair value through profit or loss. The maximum exposure at the end of the reporting period is the carrying amount of these investments.

(iii) Other financial assets at amortized costs

Other financial assets at amortized cost include time deposits, other long-term financial instruments and others. All of the financial assets at amortized costs are considered to have low credit risk, and the loss allowance recognized during the period was, therefore, limited to 12 months expected losses. Management consider ‘low credit risk’ for other instruments when they have a low risk of default and the issuer has a strong capacity to meet its contractual cash flow obligations in the near term.

(iv) Financial assets at fair value through other comprehensive income

Financial assets at fair value through other comprehensive income includeavailable-for-sale recognized in the prior financial year.

All of the debt investments at fair value through other comprehensive income are considered to have low credit risk, and the loss allowance recognized during the period was, therefore, limited to 12 months expected losses. Management consider ‘low credit risk’ for other instruments when they have a low risk of default and the issuer has a strong capacity to meet its contractual cash flow obligations in the near term.

The Group is also exposed to credit risk in relation to financial assets that are measured at fair value through other comprehensive income. The maximum exposure at the end of the reporting period is the carrying amount of these investments.

(v) Financial assets at fair value through profit or loss

The Group is also exposed to credit risk in relation to financial assets that are measured at fair value through profit or loss. The maximum exposure at the end of the reporting period is the carrying amount of these investments.

(2) Capital Risk Management

The Group’s objectives when managing capital are to safeguard the Group’s ability to continue as a going concern in order to provide returns for shareholders and benefits for other shareholders and to maintain an optimal capital structure to reduce the cost of capital.

The Group’s capital structure consists of liabilities including borrowings, cash and cash equivalents, and shareholders’ equity. The treasury department monitors the Group’s capital structure and considers cost of capital and risks related each to capital component.

Thedebt-to-equity ratios as at December 31, 2019 and 2018, are as follows:

(in millions of Korean won)	December 31, 2019			December 31, 2018
Total liabilities	W	18,874,339		W	17,457,550
Total equity		15,186,953			14,731,280
Debt-to-equity ratio		124	%		119	%

The Group manages capital on the basis of the gearing ratio. This ratio is calculated as net debt divided by total capital. Net debt is calculated as total borrowings less cash and cash equivalents. Total capital is calculated as ‘equity’ in the statement of financial position plus net debt.

(2) Fair Value Hierarchy

To provide an indication about the reliability of the inputs used in determining fair value, the Group classifies its financial instruments into the three levels prescribed under the accounting standards. Financial instruments that are measured at fair value are categorized by the fair value hierarchy, and the defined levels are as follows:

• Level 1: The fair value of financial instruments traded in active markets is based on quoted market prices at the end of the reporting period. The quoted market price used for financial assets held by the Group is the current bid price. These instruments are included in level 1.

• Level 2: The fair value of financial instruments that are not traded in an active market is determined using valuation techniques which maximize the use of observable market data and rely as little as possible on entity-specific estimates. If all significant inputs required to fair value an instrument are observable, the instrument is included in level 2.

• Level 3: If one or more of the significant inputs is not based on observable market data, the instrument is included in level 3.

Fair value hierarchy classifications of the financial assets and financial liabilities that are measured at fair value or its fair value is disclosed as at December 31, 2019 and 2018, are as follows:

(6) Gains and Losses on Valuation at the Transaction Date

In the case that the Group values derivative financial instruments using inputs not based on observable market data, and the fair value calculated by the said valuation technique differs from the transaction price, then the fair value of the financial instruments is recognized as the transaction price. The difference between the fair value at initial recognition and the transaction price is deferred and amortized using a straight-line method by maturity of the financial instrument. However, in the case that inputs of the valuation techniques become observable in markets, the remaining deferred difference is immediately recognized in full in profit for the year.

In relation to this, details and changes of the total deferred difference for the years ended December 31, 2019 and 2018, are as follows:

42. Changes in Accounting Policies

As explained in Note 2.2, the Group has adopted Korean IFRS 1116, retrospectively, from January 1, 2019, but has not restated comparatives for the 2018 reporting period, as permitted under the specific transitional provisions in the standard. The reclassifications and the adjustments arising from the new leasing rules are, therefore, recognized in the consolidated statement of financial position on January 1, 2019.

On adoption of Korean IFRS 1116, the Group recognized lease liabilities in relation to leases which had previously been classified as ‘operating leases’ under the principles of Korean IFRS 1017. These liabilities were measured at the present value of the remaining lease payments, discounted using the lessee’s incremental borrowing rate as at January 1, 2019. The weighted average lessee’s incremental borrowing rate applied to the lease liabilities on January 1, 2019 was 3.49%.

115

KT Corporation and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2019 and 2018

For leases previously classified as ‘finance leases’, the Group recognized the carrying amount of the lease asset and lease liability immediately before transition as the carrying amount of theright-of-use asset and the lease liability at the date of initial application. The measurement principles of Korean IFRS 1116 are only applied after that date.

(1) Use of practical expedients

In applying Korean IFRS 1116 for the first time, the Group used the following the practical expedients permitted by the standard:

• the use of a single discount rate to a portfolio of leases with reasonably similar characteristics

• reliance on previous assessments on whether leases are onerous

• the accounting for operating leases with a remaining lease term of less than 12 months as at January 1, 2019, as short-term leases

• the exclusion of initial direct costs for the measurement of theright-of-use asset at the date of initial application, and

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

The Group has also elected not to reassess whether a contract is, or contains a lease at the date of initial application. Instead, for contracts entered into before the transition date, the Group relied on its assessment made applying Korean IFRS 1017 and interpretation 2104Determining whether an Arrangement contains a Lease.

(2) Measurement of lease liabilities

(in millions of Korean won)	2019
Operating lease commitments as at December 31, 20181	W	675,658

Of which are:

Non-current lease liabilities		470,703
	W	807,233

¹  It excluded short-term leases and leases for which the underlying asset is of low value.

(3) Measurement ofright-of-use assets

Right-of-use assets were measured at the amount equal to the lease liability, adjusted by the amount of any prepaid or accrued lease payments relating to that lease recognized in the consolidated statement of financial position as at December 31, 2018.

KT Corporation

Opinion

We have audited the accompanying separate financial statements of KT Corporation (the Company), which comprise the separate statements of financial position as at December 31, 2019 and 2018, and the separate statements of profit or loss, separate statements of comprehensive income, separate statements of changes in equity and separate statements of cash flows for the years then ended, and notes to the separate financial statements, including a summary of significant accounting policies.

In our opinion, the accompanying separate financial statements present fairly, in all material respects, the separate financial position of the Company as at December 31, 2019 and 2018, and its separate financial performance and its separate cash flows for the years then ended in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (Korean IFRS).

We also have audited, in accordance with Korean Standards on Auditing, the Company’s Internal Control over Financial Reporting as at December 31, 2019, based on Conceptual Framework for Designing and Operating Internal Control over Financial Reporting, and our report dated March 10, 2020 expressed an unqualified opinion.

Basis for Opinion

We conducted our audits in accordance with Korean Standards on Auditing. Our responsibilities under those standards are further described in the Auditor’s Responsibilities for the Audit of the Financial Statements section of our report. We are independent of the Company in accordance with the ethical requirements of the Republic of Korea that are relevant to our audit of the separate financial statements and we have fulfilled our other ethical responsibilities in accordance with the ethical requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Key Audit Matters

Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the separate financial statements of the current period. These matters were addressed in the context of our audit of the separate financial statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters.

(1) Impairment on investments in subsidiaries, associates and joint ventures

As described in Note 14 of the separate financial statements, the carrying amount of investments in subsidiaries, associates and joint ventures is KRW 3,501,391 million in the statement of financial position, which accounts for 12.6% of the total assets of the Company as at December 31, 2019. Impairment losses on investments in subsidiaries, associates and joint ventures of KRW 172,769 million were recorded during the year ended December 31, 2019.

At the end of each reporting period, the Company assesses whether there are any indicators that the investments in subsidiaries, associates and joint venture are impaired. The Company recognizes the excess of the carrying amount over the recoverable amount as an impairment loss, if any.

As the carrying amounts of investments in subsidiaries, associates and joint ventures are material in the financial statements. The assumptions for revenue growth rate, perpetual growth rate and discount rate have a material impact in the determination of the recoverable amounts, and these assumptions involve the management’s judgment. Therefore, we determined that the impairment test of investments in subsidiaries, associates and joint ventures is a key audit matter.

We have performed the following audit procedures to address the above key audit matter:

• We obtained an understanding of management’s procedures for impairment assessment and evaluated relevant internal controls.

• We assessed management’s determination on whether or not any impairment indicators existed for the investments in subsidiaries, associates, and joint ventures.

• We evaluated the qualification and independence of external professionals used by management for the impairment assessment.

• We evaluated the appropriateness of valuation models used by management to estimate the recoverable amounts.

• We evaluated the reasonableness of key assumptions used by management to estimate the recoverable amounts.

• With the assistance of professional specialists, we assessed the reasonableness of estimates of future cash flows, discount rate and other assumptions used by management to estimate the recoverable amounts.

• We evaluated the results of a sensitivity analysis on the discount rate performed by managements to assess the impact of changes in key assumptions on the impairment assessment.

(2) Cash-Generating Unit Impairment Assessment

As described in Note 2.15 in the separate financial statements, the Company assesses whether indicators of impairment on assets exist. This assessment is completed in accordance with Korean IFRS 1036. In an impairment indicator exists, then management performs an impairment assessment. Given that there is a significant difference between the market value of the Company and the total net assets of the Company as at December 31, 2019, the Company determined that indicators of impairment on the cash-generating units (“the CGUs”) in wire, wireless and corporate business CGUs existed as at December 31, 2019. Management completed an impairment assessment, and no impairment loss was recognized as the recoverable amount of each of the CGUs exceeds their respective carrying amounts.

To determine the recoverable amounts of the CGUs, the Company estimated future cash flows which reflected forecast information such as the number of users for communication services, average profit per user (“ARPU”), and other assumptions. Another critical assumption was the determination of a discount rate to apply to these forecasted future cash flows. Significant judgment is used by management in determining these key assumptions.

The carrying amounts of assets allocated to each of the CGUs are material in the financial statements. Management’s assumptions have a significant impact on determining the recoverable amounts. This results in a high degree of judgement, effort and specialized knowledge being used by management. Therefore, we determined that the impairment assessment of assets allocated to each of the aforementioned CGUs as a key audit matter.

We have performed the following audit procedures to address the above key audit matter:

• We obtained an understanding of the Company’s procedures for asset impairment assessment and evaluated relevant internal controls.

• We obtained an understanding of the Company’s operations and assessed management’s determination of the different CGUs.

• We evaluated the qualification and independence of professionals used by management to estimate the recoverable amounts.

• We evaluated the reasonableness of key assumptions used by management to estimate the recoverable amounts.

• We assessed the reasonableness of the revenue growth rates, operating margin and forecasts of investing activities of these CGUs and compared those amounts with historical results and current market conditions.

• We evaluated the appropriateness of valuation models used by management to estimate the recoverable amounts.

• We evaluated the results of a sensitivity analysis on the discount rate performed by management to assess the impact of changes in key assumptions on the impairment assessment.

Other Matter

Auditing standards and their application in practice vary among countries. The procedures and practices used in the Republic of Korea to audit such separate financial statements may differ from those generally accepted and applied in other countries.

Responsibilities of Management and Those Charged with Governance for the Financial Statements

Management is responsible for the preparation and fair presentation of the separate financial statements in accordance with Korean IFRS, and for such internal control as management determines is necessary to enable the preparation of separate financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the separate financial statements, management is responsible for assessing the Company’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless management either intends to liquidate the Company or to cease operations.

Those charged with governance are responsible for overseeing the Company’s financial reporting process.

Auditor’s Responsibilities for the Audit of the Financial Statements

Our objectives are to obtain reasonable assurance about whether the separate financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with Korean Standards on Auditing will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these separate financial statements.

As part of an audit in accordance with Korean Standards on Auditing, we exercise professional judgment and maintain professional skepticism throughout the audit. We also:

• Identify and assess the risks of material misstatement of the separate financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.

• Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances.

• Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by management.

• Conclude on the appropriateness of management’s use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Company’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor’s report to the related disclosures in the separate financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor’s report. However, future events or conditions may cause the Company to cease to continue as a going concern.

4

• Evaluate the overall presentation, structure and content of the separate financial statements, including the disclosures, and whether the separate financial statements represent the underlying transactions and events in a manner that achieves fair presentation.

We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit.

We also provide those charged with governance with a statement that we have complied with relevant ethical requirements regarding independence, and to communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards.

From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of the separate financial statements of the current period and are therefore the key audit matters. We describe these matters in our auditor’s report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.

The engagement partner on the audit resulting in this independent auditor’s report isJin-Kyu Lee, Certified Public Accountant.

2. Significant Accounting Policies

The principal accounting policies applied in the preparation of these separate financial statements are set out below. These policies have been consistently applied to all the years presented, unless otherwise stated.

2.1 Basis of Preparation

The Company maintains its accounting records in Korean won and prepares statutory financial statements in the Korean language (Hangul) in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (Korean IFRS). The accompanying separate financial statements have been condensed, restructured and translated into English from the Korean language financial statements.

KT Corporation

Notes to the Separate Financial Statements

December 31, 2019 and 2018

The separate financial statements of the Company have been prepared in accordance with Korean IFRS. These are the standards, subsequent amendments and related interpretations issued by the International Accounting Standards Board (IASB) that have been adopted by the Republic of Korea.

The financial statements have been prepared on a historical cost basis, except for the following:

• Certain financial assets and liabilities (including derivative instruments), certain classes of property and equipment and investment property – measured at fair value

• Assetsheld-for-sale – measured at fair value less costs to sell

• Defined benefit pension plans – plan assets measured at fair value

The preparation of the separate statements requires the use of critical accounting estimates. Management also needs to exercise judgement in applying the Company’s accounting policies. The areas involving a higher degree of judgment or complexity, or areas where assumptions and estimates are significant to the separate financial statements are disclosed in Note 3.

2.2 Changes in Accounting Policies and Disclosures

(1) New and amended standards adopted by the Company

The Company has applied the following standards and amendments for the first time for their annual reporting period commencing January 1, 2019.

• Enactment of Korean IFRS 1116Leases

Under the new standard, with implementation of a single lease model, lessee is required to recognize assets and liabilities for all lease which lease term is over 12 months and underlying assets are not low value assets. A lessee is required to recognize aright-of-use asset and a lease liability representing its obligation to make lease payments.

With implementation of Korean IFRS 1116Lease, the Company has changed accounting policy. The Company has adopted Korean IFRS 1116 retrospectively, as permitted under the specific transitional provisions in the standard, and recognized the cumulative impact of initially applying the standard as at January 1, 2019, the date of initial application. The Company has not restated comparatives for the 2018 reporting period. The impact of the adoption of the leasing standard and the new accounting policies are disclosed in Note 38.

KT Corporation

Notes to the Separate Financial Statements

December 31, 2019 and 2018

• Amendment to Korean IFRS 1109Financial Instruments – Prepayment Features with Negative Compensation

The narrow-scope amendments made to Korean IFRS 1109Financial Instruments enable entities to measure certain prepayable financial assets with negative compensation at amortized cost. When a modification of a financial liability measured at amortized cost that does not result in the derecognition, a modification gain or loss shall be recognized in profit or loss. The amendment does not have a significant impact on the financial statements.

• Amendments to Korean IFRS 1019Employee Benefits – Amendment, Curtailment or Settlement of the Plan

The amendments require that an entity shall calculate current service cost and net interest for the remainder of the reporting period after a plan amendment, curtailment or settlement based on updated actuarial assumptions from the date of the change. The amendments also require that a reduction in a surplus must be recognized in profit or loss even if that surplus was not previously recognized because of the impact of the asset ceiling. The amendment does not have a significant impact on the financial statements.

• Amendment to Korean IFRS 1028Investments in Associates and Joint Ventures – Long-term Interests in Associates and Joint Ventures

The amendments clarify that an entity shall apply Korean IFRS 1109 to financial instruments in an associate or joint venture to which the equity method is not applied. These include long-term interests that, in substance, form part of the entity’s net investment in an associate or joint venture. The amendment does not have a significant impact on the financial statements.

• Enactment to Interpretation of Korean IFRS 2123Uncertainty over Income Tax Treatments

The Interpretation explains how to recognize and measure deferred and current income tax assets and liabilities where there is uncertainty over a tax treatment, and includes guidance on how to determine whether each uncertain tax treatment is considered separately or together. It also presents examples of circumstances where a judgement or estimate is required to be reassessed. The enactment does not have a significant impact on the financial statements.

• Annual Improvements to Korean IFRS 2015 – 2017 Cycle:

• Amendments to Korean IFRS 1103Business Combination

The amendments clarify that when a party to a joint arrangement obtains control of a business that is a joint operation, and had rights to the assets and obligations for the liabilities relating to that joint operation immediately before the acquisition date, the transaction is a business combination achieved in stages. In such cases, the acquirer shall remeasure its entire previously held interest in the joint operation. The amendment does not have a significant impact on the financial statements.

14

KT Corporation

Notes to the Separate Financial Statements

December 31, 2019 and 2018

• Amendments to Korean IFRS 1111Joint Agreements

The amendments clarify that when 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. In such cases, previously held interests in the joint operation are not remeasured. The amendment does not have a significant impact on the financial statements.

• Amendments to Paragraph 57A of Korean IFRS 1012Income Tax

The amendment is applied to all the income tax consequences of dividends and requires an entity to recognize the income tax consequences of dividends in profit or loss, other comprehensive income or equity according to where the entity originally recognized those past transactions or events. The amendment does not have a significant impact on the financial statements.

• Korean IFRS 1023Borrowing Costs

The amendments clarify that if a specific borrowing remains outstanding after the related qualifying asset is ready for its intended use (or sale), it becomes part of general borrowings. The amendment does not have a significant impact on the financial statements.

(2) New standards and interpretations not yet adopted by the Company

Certain new accounting standards and interpretations that have been published that are not mandatory for annual reporting period commencing January 1, 2019 and have not been early adopted by the Company are set out below.

• Amendments to Korean IFRS 1001 Presentation of Financial Statementsand Korean IFRS 1008Accounting policies, changes in accounting estimates and errors – Definition of Material

The amendments clarify the explanation of the definition of material and amended Korean IFRS 1001 and Korean IFRS 1008 in accordance with the clarified definitions. Materiality is assessed by reference to omission or misstatement of material information as well as effects of immaterial information, and to the nature of the users when determining the information to be disclosed by the Company. These amendments should be applied for annual periods beginning on or after January 1, 2020, and earlier application is permitted. The Company does not expect that these amendments have a significant impact on the financial statements.

15

KT Corporation

Notes to the Separate Financial Statements

December 31, 2019 and 2018

• Amendments to Korean IFRS 1103 Business Combination – Definition of a Business

To consider the integration of the required activities and assets as a business, the amended definition of a business requires an acquisition to include an input and a substantive process that together significantly contribute to the ability to create outputs and excludes economic benefits from the lower costs. An entity can apply an optional concentration test, in which substantially all of the fair value of gross assets acquired is concentrated in a single asset or a group of similar assets, and the assets acquired would not represent a business. These amendments should be applied for annual periods beginning on or after January 1, 2020, and earlier application is permitted. The Company does not expect that these amendments have a significant impact on the financial statements.

• Agenda Resolution of the International Accounting Standards Commission – Lease Period

The International Accounting Standards Commission (IFRS IC) announced on December 16, 2019 that all economic disadvantages resulting from the termination of a lease are taken into account when determining the enforceable period for ‘the useful life of lease term and lease asset improvement rights’. The Company is analyzing the effect of changes in accounting policies on the financial statements for enforceable periods in accordance with the decision and will reflect the effect in the financial statements after the analysis is completed.

2.3 Subsidiaries, Associates and Joint Ventures

The financial statements of the Company are separate financial statements prepared in accordance with Korean IFRS 1027 Separate Financial Statements. Investments in subsidiaries, joint ventures and associates are recognized at cost under the direct equity method. Management applied the carrying amounts under the previousK-GAAP at the time of transition to Korean IFRS as deemed cost of investments. The Company recognizes dividend income from subsidiaries, joint ventures and associates in profit or loss when its right to receive the dividend is established.

2.4 Foreign Currency Translation

(a) Functional and presentation currency

Items included in the financial statements of each of the Company are measured using the currency of the primary economic environment in which each entity operates (the “functional currency”). The separate financial statements are presented in Korean won, which is the Company’s functional and presentation currency.

(b) Transactions and balances

Foreign currency transactions are translated into the functional currency using the exchange rates at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation of monetary assets and liabilities denominated in foreign currencies at year end exchange rates are generally recognized in profit or loss. They are deferred in other comprehensive income if they relate to qualifying cash flow hedges and qualifying effective portion of net investment hedges, or are attributable to monetary part of the net investment in a foreign operation.

Foreign exchange gains and losses that relate to borrowings are presented in the statement of profit or loss, within finance costs. All other foreign exchange gains and losses are presented in the statement of profit or loss within ‘other income or other expenses’.

Non-monetary items that are measured at fair value in a foreign currency are translated using the exchange rates at the date when the fair value was determined. Translation differences on assets and liabilities carried at fair value are reported as part of the fair value gain or loss. For example, translation differences onnon-monetary assets and liabilities such as equities held at fair value through profit or loss are recognized in profit or loss as part of the fair value gain or loss and translation differences onnon-monetary assets such as equities classified asavailable-for-sale financial assets are recognized in other comprehensive income.

2.5 Financial Assets

(a) Classification

The Company classifies its financial assets in the following measurement categories:

• those to be measured at fair value through profit or loss

• those to be measured at fair value through other comprehensive income, and

• those to be measured at amortized cost.

The classification depends on the Company’s business model for managing the financial assets and the contractual terms of the cash flows.

For financial assets measured at fair value, gains and losses will either be recorded in profit or loss or other comprehensive income. For investments in debt instruments, this will depend on the business model in which the investment is held. The Company reclassifies debt investments when, and only when its business model for managing those assets changes.

For investments in equity instruments that are not held for trading, this will depend on whether the Company has made an irrevocable election at the time of initial recognition to account for the equity investment at fair value through other comprehensive income. Changes in fair value of the investments in equity instruments that are not accounted for as other comprehensive income are recognized in profit or loss.

Notes to the Separate Financial Statements

December 31, 2019 and 2018

(b) Measurement

At initial recognition, the Company measures a financial asset at its fair value plus, in the case of a financial asset not at fair value through profit or loss, transaction costs that are directly attributable to the acquisition of the financial asset or the issuance of the financial liabilities. Transaction costs of financial assets carried at fair value through profit or loss are expensed in profit or loss.

Hybrid (combined) contracts with embedded derivatives are considered in their entirety when determining whether their cash flows are solely payment of principal and interest.

A. Debt instruments

Subsequent measurement of debt instruments depends on the Company’s business model for managing the asset and the cash flow characteristics of the asset. The Company classifies its debt instruments into one of the following three measurement categories:

• Amortized cost: Assets that are held for collection of contractual cash flows where those cash flows represent solely payments of principal and interest are measured at amortized cost. A gain or loss on a debt investment that is subsequently measured at amortized cost and is not part of a hedging relationship is recognized in profit or loss when the asset is derecognized or impaired. Interest income from these financial assets is included in ‘finance income’ using the effective interest rate method.

• Fair value through other comprehensive income: Assets that are held for collection of contractual cash flows and for selling the financial assets, where the assets’ cash flows represent solely payments of principal and interest, are measured at fair value through other comprehensive income. Movements in the carrying amount are taken through other comprehensive income, except for the recognition of impairment loss (and reversal of impairment loss), interest income and foreign exchange gains and losses which are recognized in profit or loss. When the financial asset is derecognized, the cumulative gain or loss previously recognized in other comprehensive income is reclassified from equity to profit or loss. Interest income from these financial assets is included in ‘finance income’ using the effective interest rate method. Foreign exchange gains and losses are presented in ‘finance income or finance costs’ and impairment loss in ‘finance costs or operating expenses’.

• Fair value through profit or loss: Assets that do not meet the criteria for amortized cost or fair value through other comprehensive income are measured at fair value through profit or loss. A gain or loss on a debt investment that is subsequently measured at fair value through profit or loss and is not part of a hedging relationship is recognized in profit or loss and presented net in the statement of profit or loss within ‘finance income or finance costs’ in the period in which it arises.

B. Equity instruments

The Company subsequently measures all equity investments at fair value. Where the Company’s management has elected to present fair value gains and losses on equity investments in other comprehensive income, there is no subsequent reclassification of fair value gains and losses to profit or loss following the derecognition of the investment. Dividends from such investments continue to be recognized in profit or loss as ‘finance income’ when the Company’s right to receive payments is established.

Changes in the fair value of financial assets at fair value through profit or loss are recognized in ‘finance income or finance costs’ in the statement of profit or loss as applicable. Impairment loss (and reversal of impairment loss) on equity investments, measured at fair value through other comprehensive income, are not reported separately from other changes in fair value.

(c) Impairment

The Company assesses on a forward looking basis the expected credit losses associated with its debt instruments carried at amortized cost and fair value through other comprehensive income. The impairment methodology applied depends on whether there has been a significant increase in credit risk. For trade receivables and lease receivables, the Company applies the simplified approach, which requires expected lifetime credit losses to be recognized from initial recognition of the receivables.

(d) Recognition and derecognition

Regular way purchases and sales of financial assets are recognized or derecognized on trade-date, the date on which the Company commits to purchase or sell the asset. Financial assets are derecognized when the rights to receive cash flows from the financial assets have expired or have been transferred and the Company has transferred substantially all the risks and rewards of ownership.

If a transfer does not result in derecognition because the Company has retained substantially all the risks and rewards of ownership of the transferred asset, the Company continues to recognize the transferred asset in its entirety and recognizes a financial liability for the consideration received.

(e) Offsetting of financial instruments

Financial assets and liabilities are offset and the net amount reported in the statements of financial position where there is a legally enforceable right to offset the recognized amounts and there is an intention to settle on a net basis or realize the assets and settle the liability simultaneously. The legally enforceable right must not be contingent on future events and must be enforceable in the normal course of business and in the event of default, insolvency or bankruptcy of the Company or the counterparty.

2.6 Derivative Instruments

Derivatives are initially recognized at fair value on the date a derivative contract is entered into and are subsequently remeasured to their fair value at the end of each reporting period. The accounting for subsequent changes in fair value depends on whether the derivative is designated as a hedging instrument, and if so, the nature of the item being hedged. The Company has hedge relationships and designates certain derivatives as:

• hedges of a particular risk associated with the cash flows of recognized assets and liabilities and highly probable forecast transactions (cash flow hedges)

At inception of the hedge relationship, the Company documents the economic relationship between hedging instruments and hedged items including whether changes in the cash flows of the hedging instruments are expected to offset changes in the cash flows of hedged items.

The fair values of derivative financial instruments designated in hedge relationships are disclosed in Note 36.

The full fair value of a hedging derivative is classified as anon-current asset or liability when the remaining maturity of the hedged item is more than 12 months; it is classified as a current asset or liability when the remaining maturity of the hedged item is less than 12 months. Anon-derivative financial asset and anon-derivative financial liability is classified as a current ornon-current based on its expected maturity and its settlement, respectively.

The effective portion of changes in fair value of derivatives that are designated and qualify as cash flow hedges is recognized in the cash flow hedge reserve within equity, and the ineffective portion is recognized in ‘finance income (costs)’.

Amounts of changes in fair value of effective hedging instruments accumulated in equity are recognized as ‘finance income (costs)’ for the periods when the corresponding transactions affect profit or loss.

When a hedging instrument expires, or is sold, terminated, exercised, or when a hedge no longer meets the criteria for hedge accounting, any accumulated cash flow hedge reserve at that time remains in equity until the forecast transaction occurs, resulting in the recognition of anon-financial asset such as inventory. When the forecast transaction is no longer expected to occur, the cash flow hedge reserve and deferred costs of hedging that were reported in equity are immediately reclassified to profit or loss.

2.7 Trade Receivables

Trade receivables are recognized initially at the amount of consideration that is unconditional, unless they contain significant financing components when they are recognized at fair value. Trade receivables are recognized initially at fair value and subsequently measured at amortized cost using the effective interest method, less loss allowance. See Note 6 for further information about the Company’s accounting for trade receivables and Note 2.5 (c) for a description of the Company’s impairment policies.

2.8 Inventories

Inventories are stated at the lower of cost and net realizable value. Cost is determined using the moving average method, except for inventoriesin-transit.

2.9 Non-Current Assets (or Disposal Group)Held-for-Sale

Non-current assets (or disposal group) are classified as held for sale when their carrying amount will be recovered principally through a sale transaction rather than through continued use and when a sale is considered highly probable. The assets are measured at the lower amount between their carrying amount and the fair value less selling costs.

2.10 Property and Equipment

Property and equipment are stated at historical cost less accumulated depreciation and accumulated impairment losses. Historical cost includes expenditures that is directly attributable to the acquisition of the items.

Depreciation of all property and equipment, except for land, is calculated using the straight-line method to allocate their cost, net of their residual values, over their estimated useful lives as follows:

		Useful Life
Buildings		10 – 40 years
Structures		10 – 40 years
Telecommunications equipment		2 – 40 years
Others	Vehicles	4 years
	Tools	4 years
	Office equipment	2 – 4 years

The depreciation method, residual values and useful lives of property and equipment are reviewed at the end of each reporting period and, if appropriate, accounted for as changes in accounting estimates.

December 31, 2019 and 2018

2.11 Investment Property

Investment property is a property held to earn rentals or for capital appreciation or both. An investment property is measured initially at its cost. After recognition as an asset, investment property is carried at cost less accumulated depreciation and impairment losses. Investment property, except for land, is depreciated using the straight-line method over their useful lives from 10 to 40 years.

2.12 Intangible Assets

(a) Goodwill

Goodwill represents the excess of the aggregate of the consideration transferred, the amount of anynon-controlling interest in the acquiree and the acquisition date fair value of the Company’s previously held equity interest in the acquiree over the net acquired identifiable assets at the date of acquisition. Goodwill is tested annually for impairment and carried at cost less accumulated impairment losses.

For the purpose of impairment testing, goodwill acquired in a business combination is allocated to each of the CGUs, or group of CGUs, that is expected to benefit from the synergies of the combination. Goodwill is monitored at the operating segment level.

Goodwill impairment reviews are undertaken annually or more frequently if events or changes in circumstances indicate a potential impairment. The carrying amount of goodwill is compared to the recoverable amount, which is the higher of value in use and the fair value less costs to sell. Any impairment is recognized immediately as an expense and is not subsequently reversed.

(b) Intangible assets, except for goodwill

Intangible assets, except for goodwill, are initially recognized at its historical cost, and carried at cost less accumulated amortization and accumulated impairment losses. Membership rights (condominium membership and golf membership) and broadcast rights that have an indefinite useful life are not subject to amortization because there is no foreseeable limit to the period over which the assets are expected to be utilized. The Company amortizes intangible assets with a limited useful life using the straight-line method over the following periods:

	Useful Life
Development costs	6 years
Software	6 years
Industrial property rights	5 – 50 years
Frequency usage rights	5 – 10 years
Others1	2 – 50 years

¹  Membership rights (condominium membership and golf membership) included in others are classified as intangible assets with indefinite useful life.

2.13 Borrowing Costs

General and specific borrowing costs that are directly attributable to the acquisition, construction or production of a qualifying asset are capitalized during the period of time that is required to complete and prepare the asset for its intended use or sale. Investment income earned on the temporary investment of specific borrowings pending their expenditure on qualifying assets is deducted from the borrowing costs eligible for capitalization. Other borrowing costs are expensed in the period in which they are incurred.

2.14 Government Grants

Grants from the government are recognized at their fair value where there is a reasonable assurance that the grant will be received and the Company will comply with all attached conditions. Government grants related to assets are presented in the statement of financial position by setting up the grant as deferred income that is recognized in profit or loss on a systematic basis over the useful life of the asset. Grants related to income are presented as a credit in the statement of profit or loss within ‘other income’.

2.15 Impairment ofNon-Financial Assets

Goodwill and intangible assets with indefinite useful life are tested annually for impairment at the end of each reporting period. If certain assets are deemed to be impaired, their recoverable amount is estimated in order to determine the impairment loss. The Company estimates the recoverable amount for each asset, and in cases when the recoverable amount cannot be estimated for an asset, the recoverable amount of the cash generating unit to which the asset belongs is estimated. Corporate assets are allocated to individual cash generating units on a reasonable and consistent basis and if they cannot be allocated to individual cash generating units, they are allocated to the smallest group of cash generating units on a reasonable and consistent basis. An impairment loss is recognized for the amount by which the asset’s carrying amount exceeds its recoverable amount (higher of its fair value less costs of disposal and value in use). Impairment loss onnon-financial assets other than goodwill are evaluated for reversal at the end of each reporting period.

2.16 Trade and Other Payables

These amounts represent liabilities for goods and services provided to the Company prior to the end of reporting period which are unpaid. Trade and other payables are presented as current liabilities, unless payment is not due within 12 months after the reporting period. They are recognized initially at their fair value and subsequently measured at amortized cost using the effective interest method.

2.17 Financial Liabilities

(a) Classification and measurement

Financial liabilities at fair value through profit or loss are financial instruments held for trading. A financial liability is held for trading if it is incurred principally for the purpose of repurchasing in the near term. Derivatives that are not designated as hedging instruments or derivatives separated from financial instruments containing embedded derivatives are also categorized as held for trading.

The Company classifiesnon-derivative financial liabilities, except for financial liabilities at fair value through profit or loss, financial guarantee contracts and financial liabilities that arise when a transfer of financial assets does not qualify for derecognition, as financial liabilities carried at amortized cost and present as ‘trade and other payables’, ‘borrowings’, and ‘other financial liabilities’ in the statement of financial position.

Preferred shares that require mandatory redemption at a particular date are classified as liabilities. Interest expenses on these preferred shares using the effective interest method are recognized in the statement of profit or loss as ‘finance costs’, together with interest expenses recognized from other financial liabilities.

(b) Derecognition

Financial liabilities are removed from the statement of financial position when it is extinguished; for example, when the obligation specified in the contract is discharged or cancelled or expired or when the terms of an existing financial liability are substantially modified. The difference between the carrying amount of a financial liability extinguished or transferred to another party and the consideration paid (including anynon-cash assets transferred or liabilities assumed) is recognized in profit or loss.

2.18 Employee Benefits

(a) Post-employment benefits

The Company operates both defined contribution and defined benefit pension plans.

A defined contribution plan is a pension plan under which the Company pays fixed contributions into a separate entity. The contributions are recognized as employee benefit expenses when an employee has rendered service.

24

KT Corporation

Notes to the Separate Financial Statements

December 31, 2019 and 2018

A defined benefit plan is a pension plan that is not a defined contribution plan. Generally, post-employment benefits are payable after the completion of employment, and the benefit amount depended on the employee’s age, periods of service or salary levels. The liability recognized in the statement of financial position in respect of defined benefit pension plans is the present value of the defined benefit obligation at the end of the reporting period less the fair value of plan assets. The defined benefit obligation is calculated annually using the projected unit credit method. The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows using interest rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be paid, and that have terms approximating to the terms of the related obligation. Remeasurement gains and losses arising from experience adjustments and changes in actuarial assumptions are recognized in the period in which they occur, directly in other comprehensive income.

Changes in the present value of the defined benefit obligation resulting from plan amendments or curtailments are recognized immediately in profit or loss as past service costs.

(b) Termination benefits

Termination benefits are payable when employment is terminated by the Company before the normal retirement date, or whenever an employee accepts voluntary redundancy in exchange for these benefits. The Company recognizes termination benefits at the earlier of the following dates: when the entity can no longer withdraw the offer of those benefits or when the entity recognizes costs for a restructuring.

(c) Long-term employee benefits

Certain entities within the Company provide long-term employee benefits that are entitled to employees with service period for ten years and above. The expected costs of these benefits are accrued over the period of employment using the same accounting methodology as used for defined benefit pension plans. The Company recognizes service cost, net interest on other long-term employee benefits and remeasurements as profit or loss for the year. These liabilities are valued annually by an independent qualified actuary.

2.19 Share-Based Payments

Equity-settled share-based payment is recognized at fair value of equity instruments granted, and employee benefit expense is recognized over the vesting period. At the end of each period, the Company revises its estimates of the number of options that are expected to vest based on thenon-market vesting and service conditions. It recognizes the impact of the revision to original estimates, if any, in profit or loss, with a corresponding adjustment to equity.

25

KT Corporation

Notes to the Separate Financial Statements

December 31, 2019 and 2018

2.20 Provisions

Provisions for service warranties, recoveries, litigations and claims, and others are recognized when the Company presently holds legal or constructive obligation as a result of past events, and when it is probable that an outflow of resources will be required to settle the obligation and the amount can be reliably estimated. Provisions are measured at the present value of management’s best estimate of the expenditure required to settle the present obligation at the end of the reporting period, and the increase in the provision due to the passage of time is recognized as interest expense.

2.21 Leases

As noted in “Note 2.2 (1)”, the Company has changed its accounting policy for leases. Information on the impact of the new accounting policy is provided in Note 38.

As at December 31, 2018, leases of property and equipment where the Company, as lessee, had substantially all the risks and rewards of ownership were classified as finance leases. Finance leases were capitalized at the lease’s inception at the fair value of the leased property or, if lower, the present value of the minimum lease payments. The corresponding lease payments, net of finance charges, were included in other payables. Each lease payment was allocated between liability and finance cost. The finance cost was charged to profit or loss over the lease period in order to produce a constant periodic rate of interest on the remaining balance of the liability for each period. Property and equipment acquired under finance leases were depreciated over the asset’s useful life, or over the shorter of the asset’s useful life and the lease term, if it was not reasonably certain that the Company will obtain ownership at the end of the lease term.

Leases in which a significant portion of the risks and rewards of ownership were not transferred to the Company as lessee were classified as operating leases. Payments made under operating leases (net of any incentives received from the lessor) were charged to profit or loss on a straight-line basis over the lease period.

(a) Lessee

The Company leases various repeater server racks, offices, track facilities, machinery, and cars.

Contracts may contain both lease andnon-lease components. The Company allocates the consideration in the contract to the lease andnon-lease components based on their relative stand-alone prices. However, for leases of real estate for which the Company is lessee, the Company applies the practical expedient which has elected not to separate lease andnon-lease components and instead accounts them as a single lease component.

Until the financial year of 2018, leases of property and equipment were classified as either finance or operating leases. Payments made under operating leases (net of any incentives received from the lessor) were charged to profit or loss on a straight-line basis over the period of the lease.

From January 1, 2019, leases are recognized as aright-of-use asset and a corresponding liability at the date at which the leased asset is available for use by the Company.

26

KT Corporation

Notes to the Separate Financial Statements

December 31, 2019 and 2018

Assets and liabilities arising from a lease are initially measured on a present value basis. Lease liabilities include the net present value of the following lease payments:

• Fixed payments (includingin-substance fixed payments), less any lease incentives receivable

• Variable lease payment that are based on an index or a rate, initially measured using the index or rate as at the commencement date

• Amounts expected to be payable by the Company (the lessee) under residual value guarantees

• The exercise price of a purchase option if the Company (the lessee) is reasonably certain to exercise that option, and

• Payments of penalties for terminating the lease, if the lease term reflects the Company (the lessee) exercising that option

Lease liability measurement also include payments to be made in option periods if the lessee is reasonably certain in exercising an option to extend the lease.

The Company determines the lease term as thenon-cancellable period of a lease, together with both (a) periods covered by an option to extend the lease if the lessee is reasonably certain to exercise that option; and (b) periods covered by an option to terminate the lease if the lessee is reasonably certain not to exercise that option. When the lessee and the lessor each has the right to terminate the lease without permission from the other party, the Company should consider a termination penalty in determining the period for which the contract is enforceable.

The lease payments are discounted using the interest rate implicit in the lease. If that rate cannot be determined, the lessee’s incremental borrowing rate is used, which is the rate that the lessee would have to pay to borrow the funds necessary to obtain an asset of similar value in a similar economic environment with similar terms and conditions.

The Company is exposed to potential future increases in variable lease payments based on an index or rate, which are not included in the lease liability until they take effect. When adjustments to lease payments based on an index or rate take effect, the lease liability is reassessed and adjusted against theright-of-use asset.

Each lease payment is allocated between the liability and finance cost. The finance cost is charged to profit or loss over the lease period in order to produce a constant periodic rate of interest on the remaining balance of the liability for each period.

27

KT Corporation

Notes to the Separate Financial Statements

December 31, 2019 and 2018

Right-of-use assets are measured at cost comprising the following:

• amount of the initial measurement of lease liability

• any lease payments made at or before the commencement date less any lease incentives received

• any initial direct costs

• restoration costs, and

• present value discount on leasehold deposits

Theright-of-use asset is depreciated over the shorter of the asset’s useful life and the lease term on a straight-line basis. If the Company is reasonably certain to exercise a purchase option, theright-of-use asset is depreciated over the underlying asset’s useful life.

Payments associated with short-term leases and leases oflow-value assets are recognized on a straight-line basis as an expense in profit or loss. Short-term leases are leases with a lease term of 12 months or less, such as mechanical devices and cars.Low-value assets are comprised of tools, equipment, and others.

(b) Lessor

Lease income from operating leases where the Company is a lessor is recognized in income on a straight-line basis over the lease term. Initial direct costs incurred in obtaining an operating lease are added to the carrying amount of the underlying asset and recognized as expense over the lease term on the same basis as lease income. The respective leased assets are included in the statement of financial position based on their nature. As a result of adopting the new lease standard, the Company applied the accounting for assets held as a lessor.

2.22 Share Capital

The Company classifies ordinary shares as equity.

Where the Company purchases its own shares, the consideration paid including any directly attributable incremental costs is deducted from equity attributable to the equity holders of the Company until the share are cancelled or reissued. When these treasury shares are reissued, any consideration received is included in equity attributable to the equity holders of the Company.

2.23 Revenue Recognition

(a) Identifying performance obligations

The Company mainly provides telecommunication services and sells handsets. The Company identifies performance obligations with a customer such as providing telecommunication services, selling handsets and other. The revenue from handsets is recognized when a performance obligation is satisfied by transferring promised goods to customers, and the revenue from telecommunication services is recognized over the estimated contract periods of each services by transferring promised services to customers.

(b) Allocation the transaction price and revenue recognition

The Company allocates the transaction price to each performance obligation identified in the contract based on a relative stand-alone selling prices of the goods or services being provided to the customer. To allocate the transaction price to each performance obligation on a relative stand-alone price basis, the Company determines the stand-alone selling price at contract inception of the distinct good or service underlying each performance obligation in the contract and allocate the transaction price in proportion to those stand-alone selling price. The stand-alone selling price is the price at which the Company would sell a promised good or service separately to the customer. The best evidence of a stand-alone selling price is the observable price of a good or service when the Company sells that good or service separately in similar circumstances and to similar customers. The Company recognizes the allocated amount as contract assets or contract liabilities, and amortizes it through the remaining period which is adjusted in operating income.

(c) Incremental contract acquisition costs

The Company pays the commission fees when new customers subscribe for telecommunication services. The incremental contract acquisition costs are those commission fees that the Company incurs to acquire a contract with a customer that would not have been incurred if the contract had not been acquired. The Company recognizes the incremental contract acquisition costs as an asset and amortizes it over the expected period of benefit. However, as a practical expedient, the Company may recognize the incremental contract acquisition cost as an expense when it is incurred if the amortization period of the asset is one year or less.

2.24 Current and Deferred Tax

The tax expense for the period consists of current and deferred tax. Current and deferred tax is recognized in profit or loss, except to the extent that it relates to items recognized in other comprehensive income or directly in equity. In this case, the tax is also recognized in other comprehensive income or directly in equity, respectively.

The tax expense is measured at the amount expected to be paid to the taxation authorities, using the tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period.

29

KT Corporation

Notes to the Separate Financial Statements

December 31, 2019 and 2018

Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation. The Company recognizes current income tax on the basis of amounts expected to be paid to the tax authorities.

Deferred income tax is provided in full, using the liability method, on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the separate financial statements. However, deferred income tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither accounting profit nor taxable profit or loss.

Deferred tax assets are recognized only if it is probable that future taxable amounts will be available to utilize those temporary differences and losses.

The Company recognizes a deferred tax liability all taxable temporary differences associated with investments in subsidiaries, associates, and interests in joint arrangements, except to the extent that the Company is able to control the timing of the reversal of the temporary difference and it is probable that the temporary difference will not reverse in the foreseeable future. In addition, the Company recognizes a deferred tax asset for all deductible temporary differences arising from such investments to the extent that it is probable the temporary difference will reverse in the foreseeable future and taxable profit will be available against which the temporary difference can be utilized.

Deferred tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets and liabilities and when the deferred tax balances relate to the same taxation authority. Current tax assets and liabilities are offset when the Company has a legally enforceable right to offset and intends either to settle on a net basis, or to realize the assets and settle the liability simultaneously.

The Company adopts the consolidated corporate tax return and calculates income tax expenses and income tax liabilities of the Company and its subsidiaries based on systematic and reasonable methods.

2.25 Dividend

Dividend distribution to the Company’s shareholders is recognized as a liability in the financial statements in the period in which the dividends are approved by the Company’s shareholders.

2.26 Approval of Issuance of the Financial Statements

The separate financial statements of 2019 were approved for issuance by the Board of Directors on February 6, 2020 and are subject to change with the approval of shareholders at their Annual General Meeting.

3. Critical Accounting Estimates and Assumptions

The preparation of financial statements requires the Company to make estimates and assumptions concerning the future. Management also needs to exercise judgement in applying the Company’s accounting policies. Estimates and assumptions are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. As the resulting accounting estimates will, by definition, seldom equal the related actual results, it can contain a significant risk of causing a material adjustment.

The estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are discussed below. Additional information of significant judgement and assumptions of certain items are included in the relevant notes.

3.1 Impairment ofNon-Financial Assets (including Goodwill)

The Company determines the recoverable amount of a cash generating unit (CGU) based on fair value orvalue-in-use calculations to assessnon-financial assets (including goodwill) for impairment (Notes 13, 14).

3.2 Income Taxes

The Company’s taxable income generated from these operations are subject to income taxes based on tax laws and interpretations of tax authorities in numerous jurisdictions. There are many transactions and calculations for which the ultimate tax determination is uncertain (Note 30).

If certain portion of the taxable income is not used for investments or increase in wages or dividends in accordance with the Tax System for Recirculation of Corporate Income, the Company is liable to pay additional income tax calculated based on the tax laws. Accordingly, the measurement of current and deferred income tax is affected by the tax effects from the new system. As the Company’s income tax is dependent on the investments, as well as wage and dividends increase, there is an uncertainty in measuring the final tax effects.

3.3 Fair Value of Financial Instruments

The fair value of financial instruments that are not traded in an active market is determined by using valuation techniques. The Company uses its judgment to select a variety of methods and makes assumptions that are mainly based on market conditions existing at the end of each reporting period (Note 37).

3.4 Impairment of Financial Assets

The provisions for impairment for financial assets are based on assumptions about risk of default and expected loss rates. The Company uses judgement in making these assumptions and selecting the inputs to the impairment calculation based on the Company’s past history, existing market conditions as well as forward looking estimates at the end of each reporting period (Note 36).

3.5 Net Defined Benefit Liability

The present value of net defined benefit liability depends on a number of factors that are determined on an actuarial basis using a number of assumptions including the discount rate (Note 18).

3.6 Amortization of Contract Assets, Contract Liabilities and Contract Cost Assets

Contract assets, contract liabilities and contract cost assets recognized under the application of Korean IFRS 1115 are amortized over the expected periods of customer relationships. The estimate of the expected terms of customer relationship is based on the historical data. If management’s estimate changes, it may cause significant differences in the timing of revenue recognition and amounts recognized.

3.7 Provisions

As described in Note 17, the Company records provisions for litigation and assets retirement obligations as at the end of the reporting period. The provisions are estimated based on the factors such as the historical experiences.

3.8 Useful Lives of Property and Equipment and Investment Property

Property and equipment, intangible assets, and investment properties, excluding land, goodwill, condominium memberships and golf club memberships, are depreciated using the straight-line method over their useful lives. The estimated useful lives are determined based on expected usage of the assets and the estimates can be materially affected by technical changes and other factors. The Company will increase depreciation expenses if the useful lives are considered shorter than the previously estimated useful lives.

Impairment test for investments in subsidiaries, associates and joint ventures

The cost method is applied to account for investments in subsidiaries, associates and joint ventures and is reviewed for any indications that an impairment loss may have occurred at the end of each reporting period. If there are such indications, the recoverable amount of the asset is estimated using the future cash flow discount method, and if the recoverable amount falls short of the carrying amount, the carrying amount of the asset is reduced and the impairment loss is immediately recognized as current term loss.

The difference between recoverable amount and carrying amount ofW63,826 million was recognized as other expenses in relation to the subsidiary ‘KT M mobile Co., Ltd.’ during the current term, and the discount rate applied to the expected future cash flow is 8.2%.

The difference between recoverable amount and carrying amount betweenW31,769 million (2018:W31,920 million) in relation to ‘KT Belgium’, a subsidiary company, was recognized as other expenses during the current term, and the discount rate applied to the expected future cash flows is 12.8%.

In relation to ‘KBTO Sp.z o.o.’, a subsidiary company, during the current term, the difference between recoverable amount and carrying amount ofW3,828 million (2018:W11,740 million) was recognized as other expenses.

Principal actuarial assumptions were as follows:

Discount rate		1.97	%		2.33	%
Future salary increases		5.37	%		5.75	%

The sensitivity of the defined benefit obligations as at December 31, 2019, to changes in the principal assumptions is:

(in millions of Korean won)	Effect on defined benefit obligation
	Changes in assumption			Increase in assumption			Decrease in assumption
Discount rate		0.5	%p	W	(59,900	)	W	63,729
Future salary growth rate		0.5	%p		56,531			(53,797	)

A decrease in corporate bond yields will increase plan liabilities, although this will be partially offset by an increase in the value of the plans’ bond holdings.

The above sensitivity analyses are based on a change in an assumption while holding all other assumptions constant. In practice, this is unlikely to occur, and changes in some of the assumptions may be correlated. The sensitivity of the defined benefit obligation to changes in principal actuarial assumptions is calculated using the projected unit credit method, the same method applied when calculating the defined benefit obligations recognized on the statement of financial position.

36. Financial Risk Management

(1) Financial Risk Factors

The Company’s activities expose it to a variety of financial risks: market risk, credit risk and liquidity risk. The Company’s overall risk management program focuses on the unpredictability of financial markets and seeks to minimize potential adverse effects on the Company’s financial performance. The Company uses derivatives to hedge certain financial risk exposures such as cash flow risk.

The Company’s financial policy is set up in the long-term perspective and annually reported to the Board of Directors. The financial risk management is carried out by the Value Management Office, which identifies, evaluates and hedges financial risks. The treasury department in the Value Management Office considers various market conditions to estimate the effect from the market changes.

(1) Market risk

The Company’s market risk management focuses on controlling the extent of exposure to the risk in order to minimize revenue volatility. Market risk is a risk that decreases value or profit of the Company’s portfolio due to changes in market interest rate, foreign exchange rate and other factors.

i) Sensitivity analysis

Sensitivity analysis is performed for each type of market risk to which the Company is exposed. Reasonably possible changes in the relevant risk variable such as prevailing market interest rates, currency rates, equity prices or commodity prices are estimated and if the rate of change in the underlying risk variable is stable, the Company does not alter the chosen reasonably possible change in the risk variable. The reasonably possible change does not include remote or ‘worst case’ scenarios or ‘stress tests’.

ii) Foreign exchange risk

The Company is exposed to foreign exchange risk arising from operating, investing and financing activities. Foreign exchange risk is managed within the range of the possible effect on the Company’s cash flows. Foreign exchange risk (i.e, foreign currency translation of overseas operating assets and liabilities) not affecting the Company’s cash flows is not hedged but can be hedged at a particular situation.

KT Corporation

Notes to the Separate Financial Statements

December 31, 2019 and 2018

As at December 31, 2019 and 2018, if the foreign exchange rate had strengthened/weakened by 10% with all other variables held constant, the effects on profit before income tax and equity would have been as follows:

(in millions of Korean won)	Fluctuation of foreign exchange rate			Income before tax 1			Equity
2019.12.31		+ 10	%	W	(4,152	)	W	1,535
		- 10	%		4,152			(1,535	)
2018.12.31		+ 10	%	W	(3,322	)	W	(2,509	)
		- 10	%		3,322			2,509

¹  Computed with considering derivatives hedging effect applied by the Company to hedge foreign exchange risk of liabilities in foreign currencies.

The above analysis is a simple sensitivity analysis which assumes that all the variables other than foreign exchange rates are held constant. Therefore, the analysis does not reflect any correlation between foreign exchange rates and other variables, nor management’s decision to decrease the risk.

Details of financial assets and liabilities in foreign currencies as at December 31, 2019 and 2018, are as follows:

(in thousands of foreign currencies)	December 31, 2019				December 31, 2018

Notes to the Separate Financial Statements

December 31, 2019 and 2018

iii) Price risk

As at December 31, 2019, the Company is exposed to equity securities price risk because the securities held by the Company are traded in active markets. If the market prices had increased/decreased by 10% with all other variables held constant, the effects on profit before income tax and equity would have been as follows:

(in millions of Korean won)	Fluctuation of price			Income before tax			Equity
2019.12.31		+ 10	%	W	23		W	224
		- 10	%		(23	)		(224	)
2018.12.31		+ 10	%	W	12		W	322
		- 10	%		(12	)		(322	)

The above analysis is based on the assumption that the equity index had increased/decreased by 10% with all other variables held constant and all the Company’s marketable equity instruments had moved according to the historical correlation with the index. Equity would increase/decrease as a result of gain or loss on equity securities classified as financial assets at fair value through profit or loss and financial assets at fair value through other comprehensive income.

iv) Cash flow and fair value interest rate risk

The Company’s interest rate risk arises from liabilities in foreign currency such as foreign currency debentures. Debentures in foreign currency issued at variable rates expose the Company to cash flow interest rate risk which is partially offset by swap transactions. Debentures and borrowings issued at fixed rates expose the Company to fair value interest rate risk. The Company sets the policy and operates to minimize the uncertainty of the changes in interest rates and financial costs.

As at December 31, 2019 and 2018, if the market interest rate had increased/decreased by 100bp with other variables held constant, the effects on profit before income tax and equity would be as follows:

(in millions of Korean won)	Fluctuation of interest rate		Income before tax			Equity
2019.12.31		+ 100 bp	W	112		W	15,073
		- 100 bp		(169	)		(19,657	)
2018.12.31		+ 100 bp	W	120		W	9,540
		- 100 bp		(1,019	)		(10,155	)

The above analysis is a simple sensitivity analysis which assumes that all the variables other than market interest rates are held constant. Therefore, the analysis does not reflect any correlation between market interest rates and other variables, nor the management’s decision to decrease the risk.

(2) Credit risk

Credit risk is the risk of financial loss to the Company if a customer or counterparty to a financial instrument fails to meet its contractual obligations, and arises principally from the Company’s trade receivables from customers, debt securities and others

• Risk management

Credit risk is managed on the Company basis with the purpose of minimizing financial loss. Credit risk arises from the normal transactions and investing activities, where clients or other party fails to discharge an obligation on contract conditions. To manage credit risk, the Company considers the counterparty’s credit based on the counterparty’s financial conditions, default history and other important factors.

Credit risk arises from cash and cash equivalents, derivative financial instruments and deposits with banks and financial institutions, as well as outstanding receivables. To minimize such risk, only the financial institutions with strong credit ratings are accepted.

The Company’s investments in debt instruments are considered to be low risk investments. The credit ratings of the investments are monitored for credit deterioration.

• Security

For some trade receivables, the Company may obtain security in the form of guarantees or letters of credit, etc. which can be called upon if the counterparty is in default under the terms of the agreement.

• Impairment of financial assets

The Company has three types of financial assets that are subject to the expected credit loss model:

• trade receivables for sales of goods and provision of services,

• contract assets relating to provision of services, and

• other financial assets carried at amortized cost.

While cash equivalents are also subject to the impairment requirement, the identified impairment loss was immaterial.

KT Corporation

Notes to the Separate Financial Statements

December 31, 2019 and 2018

The maximum exposure to credit risk of the Company’s financial instruments without considering value of collaterals as at December 31, 2019 and 2018, are as follows:

(in millions of Korean won)	December 31, 2019		December 31, 2018
Cash and cash equivalents (except for cash on hand)	W	1,326,703	W	1,778,565
Trade and other receivables
Financial assets at amortized costs		3,038,182		2,637,732
Financial assets at fair value through other comprehensive income		1,256,266		1,097,348
Contract assets		512,908		366,866
Other financial assets
Derivatives financial assets for hedging purposes		55,423		29,843
Financial assets at fair value through profit or loss		131,112		101,156
Financial assets at amortized costs		72,329		54,074
Total	W	6,392,923	W	6,065,584

i) Trade and other receivables and contract assets

The Company applies the simplified approach to measuring expected credit losses which uses a lifetime expected loss allowance for all trade and other receivables and contract assets.

The Company measures the expected credit loss by considering the future irrecoverability rate of the remaining balance of trade receivables and other receivables at the end of the reporting period. Each trade receivables and other receivables are classified considering the credit risk characteristics and overdue periods in order to measure expected credit loss. The expected credit loss rate calculation is based on historical payment and credit loss information in relation to revenue for 36 months period up to December 31, 2019.

ii) Cash equivalents (except for cash on hand)

The Company is also exposed to credit risk in relation to cash equivalents. The maximum exposure at the end of the reporting period is the carrying amount of these investments.

iii) Other financial assets at amortized costs

Other financial assets at amortized cost include time deposits, other long-term financial instruments and others.

All of the financial assets at amortized costs are considered to have low credit risk, and the loss allowance recognized during the period was, therefore, limited to 12 months expected losses.

83

KT Corporation

Notes to the Separate Financial Statements

December 31, 2019 and 2018

Management consider ‘low credit risk’ for other instruments when they have a low risk of default and the issuer has a strong capacity to meet its contractual cash flow obligations in the near term.

iv) Financial assets at fair value through other comprehensive income

The Company is also exposed to credit risk in relation to financial assets at fair value through other comprehensive income. The maximum exposure at the end of the reporting period is equal to the carrying amount of these investments.

v) Financial assets at fair value through profit or loss

The Company is also exposed to credit risk in relation to financial assets that are measured at fair value through profit or loss. The maximum exposure at the end of the reporting period is the carrying amount of these investments.

(3) Liquidity risk

The Company manages its liquidity risk by liquidity strategy and plans. The Company considers the maturity of financial assets and financial liabilities and the estimated cash flows from operations.

The table below analyzes the Company’s liabilities (including interest expenses) into relevant maturity groups based on the remaining period at the report date to the contractual maturity date and these amounts are contractual undiscounted cash flows:

(2) Capital Risk Management

The Company’s objectives when managing capital are to safeguard the Company’s ability to continue as a going concern in order to provide returns for shareholders and benefits for other stakeholders and to maintain an optimal capital structure to reduce the cost of capital.

The Company’s capital structure consists of liabilities including borrowings, cash and cash equivalents, and shareholders’ equity. The treasury department monitors the Company’s capital structure and considers cost of capital and risks related to each capital component.

The Company’sdebt-to-equity ratios as at December 31, 2019 and 2018, are as follows:

(in millions of Korean won)	December 31, 2019			December 31, 2018
Total liabilities	W	14,837,153		W	13,299,178
Total equity		12,896,701			12,711,728
Debt-to-equity ratio		115	%		105	%

The Company manages capital on the basis of the gearing ratio. The ratio is calculated as net debt divided by total capital. Net debt is calculated as total borrowings less cash and cash equivalents. Total capital is calculated as ‘equity’ as shown in the statement of financial position plus net debt.

(2) Fair Value Hierarchy

Assets measured at fair value or for which the fair value is disclosed are categorized within the fair value hierarchy, and the defined levels are as follows:

• Level 1: The fair value of financial instruments traded in active markets is based on quoted market prices at the end of the reporting period. The quoted market price used for financial assets held by the Company is the current bid price. These instruments are included in level 1.

• Level 2: The fair value of financial instruments that are not traded in an active market is determined using valuation techniques which maximize the use of observable market data and rely as little as possible on entity-specific estimates. If all significant inputs required to fair value an instrument are observable, the instrument is included in level 2.

• Level 3: If one or more of the significant inputs is not based on observable market data, the instrument is included in level 3.

Fair value hierarchy classifications of the financial assets and financial liabilities that are measured at fair value or its fair value is disclosed as at December 31, 2019 and 2018, are as follows:

(5) Valuation Processes for Fair Value Measurements Categorized Within Level 3

The Company uses external experts that perform the fair value measurements required for financial reporting purposes. External experts report directly to the chief financial officer (CFO), and discusses valuation processes and results with the CFO in line with the Company’s closing dates.

(6) Gains and Losses on Valuation at the Transaction Date

In the case that the Company values derivative financial instruments using inputs not based on observable market data, and the fair value calculated by the said valuation technique differs from the transaction price, then the fair value of the financial instruments is recognized as the transaction price. The difference between the fair value at initial recognition and the transaction price is deferred and amortized using a straight-line method by maturity of the financial instrument. However, in the case where inputs of the valuation techniques become observable in markets, the remaining deferred difference is immediately recognized in full as profit for the year.

38. Changes in Accounting Policies

As explained in Note 2.2 (1), the Company has adopted Korean IFRS 1116, retrospectively, from January 1, 2019, but has not restated comparatives for the 2018 reporting period, as permitted under the specific transitional provisions in the standard. The reclassifications and the adjustments arising from the new leasing rules are, therefore, recognized in the statement of financial position on January 1, 2019.

On adoption of Korean IFRS 1116, the Company recognized lease liabilities in relation to leases which had previously been classified as ‘operating leases’ under the principles of Korean IFRS 1017. These liabilities were measured at the present value of the remaining lease payments, discounted using the lessee’s incremental borrowing rate as at January 1, 2019. The weighted average lessee’s incremental borrowing rate applied to the lease liabilities on January 1, 2019 was 3.22%.

For leases previously classified as ‘finance leases’, the Company recognized the carrying amount of the lease asset and lease liability immediately before transition as the carrying amount of theright-of-use asset and the lease liability at the date of initial application. The measurement principles of Korean IFRS 1116 are only applied after that date.

(1) Use of practical expedients

In its initial application of Korean IFRS 1116, the Company used the following practical expedients permitted by the Standard:

• Evaluating the impairment of theright-to-use assets that relied on previous assessments of whether a lease was a loss-making contract

The company did not reassess whether the contract was a lease or whether the lease was embedded as of the date of initial application. Instead, for contracts entered into before the date of initial application, Korean IFRS 1116 was applied to contracts previously identified as leases by applying Korean IFRS 1017 and interpretation 2104Determining whether an Arrangement contains a Lease.

Non-current lease liabilities		470,429
	W	783,900

¹  It excluded short-term leases and leases for which the underlying asset is of low value.

(3) Measurement ofright-of-use assets

Right-of-use assets were measured at the amount equal to the lease liability, adjusted by the amount of any prepaid or accrued lease payments relating to that lease recognized in the statement of financial position as at December 31, 2018.

(4) Adjustments to the separate statement of financial position at initial adoption

The change in accounting policy affected the following items in the statement of financial position on January 1, 2019:

An audit of internal control over financial reporting involves performing procedures to obtain audit evidence about whether a material weakness exists. The procedures selected depend on the auditor’s judgment, including the assessment of the risks that a material weakness exists. An audit includes obtaining an understanding of internal control over financial reporting and testing and evaluating the design and operating effectiveness of internal control over financial reporting based on the assessed risk.

Definition and Inherent Limitations of Internal Control over Financial Reporting

An entity’s internal control over financial reporting is a process effected by those charged with governance, management, and other personnel, designed to provide reasonable assurance regarding the preparation of reliable financial statements in accordance with International Financial Reporting Standards as adopted by the Republic of Korea. An entity’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 entity; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with International Financial Reporting Standards as adopted by the Republic of Korea, and that receipts and expenditures of the entity are being made only in accordance with authorizations of management and those charged with governance; and (3) provide reasonable assurance regarding prevention, or timely detection and correction of unauthorized acquisition, use, or disposition of the entity’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 and correct, misstatements. Also, projections of any assessment 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.

The engagement partner on the audit resulting in this independent auditor’s report isJin-Kyu Lee, Certified Public Accountant.
