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, 2022 and 2021, 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, 2022 and 2021, 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 in forming our opinion thereon, and we do not provide a separate opinion on these matters.

Cash-Generating Unit Impairment Assessment of the Controlling Company (KT Corporation) and HCN Co., Ltd.

1)	Why the matter was determined to be a key audit matter

As described in Note 2.16 and Note 13 in the consolidated financial statements, the Group assesses whether indicators of impairment on assets exist at the end of every reporting period. When an impairment indicator exists, then management performs an impairment test. This assessment is completed in accordance with Korean IFRS 1036 Impairment of Assets.

A. Cash-Generating Unit Impairment Assessment of the Controlling Company

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, 2022, the Group determined that indicators of impairment on the cash-generating units (the “CGUs”) in wire, wireless and corporate business CGUs in the Controlling Company existed as at December 31, 2022. 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 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 consolidated 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 Group’s impairment assessment of assets allocated to each of the aforementioned CGUs as a key audit matter.

B. Cash-Generating Unit Impairment Assessment of HCN Co., Ltd.

The Group performed impairment assessment as of December 31, 2022 as the amount of goodwill allocated to HCN Co., Ltd.’s cash-generating unit in the prior year was KRW 252,679 million. As a result of the assessment, the Group recognized KRW 24,005 million of impairment loss.

2)	How the matter was addressed in the audit:

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<br>relevant internal controls.
•	We obtained an understanding of the Group’s procedures to identify the CGUs and evaluated relevant internal<br>controls.
---	---
•	We evaluated the appropriateness of valuation models used by management to estimate the recoverable amounts.<br>
---	---
•	We evaluated the appropriateness of internal and external information used by management to estimate the<br>recoverable amounts.
---	---
•	We assessed the consistency of key assumptions used by management to estimate the recoverable amounts, by<br>comparing the historical results, current market conditions and future business plans.
---	---
•	We evaluated the qualifications and independence of management’s external experts.
---	---

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.

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 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<br>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<br>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<br>appropriate in the circumstances.
---	---
•	Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and<br>related disclosures made by management.
---	---
•	Conclude on the appropriateness of management’s use of the going concern basis of accounting and, based on<br>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<br>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<br>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<br>disclosures, and whether the consolidated financial statements represent the underlying transactions and events in a manner that achieves fair presentation.
---	---
•	Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business<br>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.<br>
---	---

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 Ho-Sung Han, Certified Public Accountant.

Notes to the Consolidated Financial Statements

December 31, 2022 and 2021

2.	Significant Accounting Policies

The principal accounting policies applied in the preparation of these consolidated 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 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)
•	Assets held-for-sale –<br>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, 2022.

•	Amendments to Korean IFRS 1116 Leases – Concession on COVID-19– Related Rent Concessions Beyond June 30, 2021

The application of the practical expedient, a lessee may elect not to assess whether a rent concession occurring as a direct consequence of the COVID-19 pandemic is a lease modification, is extended to lease payments originally due on or before June 30, 2022. A lessee shall apply the practical expedient consistently to eligible contracts with similar characteristics and in similar circumstances. The amendments do not have a significant impact on the consolidated financial statements.

Notes to the Consolidated Financial Statements

December 31, 2022 and 2021

•	Amendments to Korean IFRS 1103 Business Combination – Reference to the Conceptual Framework<br>

The amendments update a reference of definition of assets and liabilities to be recognized in a business combination in revised Conceptual Framework for Financial Reporting. However, the amendments add an exception for the recognition of liabilities and contingent liabilities within the scope of Korean IFRS 1037 Provisions, Contingent Liabilities and ContingentAssets, and Korean IFRS 2121 Levies. The amendments also clarify that contingent assets should not be recognized at the acquisition date. The amendments do not have a significant impact on the consolidated financial statements.

•	Amendments to Korean IFRS 1016 Property, Plant and Equipment – Proceeds Before Intended Use<br>

The amendments prohibit an entity from deducting from the cost of an item of property, plant and equipment any proceeds from selling items produced while the entity is preparing the asset for its intended use. Instead, the entity will recognize the proceeds from selling such items, and the costs of producing those items, in profit or loss. The amendments do not have a significant impact on the consolidated financial statements.

•	Amendments to Korean IFRS 1037 Provisions, Contingent Liabilities and Contingent Assets – OnerousContracts: Cost of Fulfilling a Contract

The amendments clarify that the direct costs of fulfilling a contract include both the incremental costs of fulfilling the contract and an allocation of other costs directly related to fulfilling contracts when assessing whether the contract is onerous. The amendments do not have a significant impact on the consolidated financial statements.

•	Annual improvements to Korean IFRS 2018-2020

Annual improvements of Korean IFRS 2018-2020 Cycle should be applied for annual periods beginning on or after January 1, 2022, and earlier application is permitted. The amendments do not have a significant impact on the consolidated financial statements.

•	Korean IFRS 1101 First Time Adoption of Korean International Financial Reporting Standards –<br>Subsidiaries that are first-time adopters
•	Korean IFRS 1109 Financial Instruments – Fees related to the 10% test for derecognition of financial<br>liabilities

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

The following new accounting standards and interpretations that have been published are not mandatory for December 31, 2022 reporting periods and have not been early adopted by the Group.

•	Amendments to Korean IFRS 1001 Presentation of Financial Statements – Classification of Liabilities asCurrent or Non-Current

The amendments clarify that liabilities are classified as either current or non-current, depending on the substantive rights that exist at the end of the reporting period. Classification is unaffected by the likelihood that an entity will exercise right to defer settlement of the liability or the expectations of management. Also, the settlement of liability include the transfer of the entity’s own equity instruments, however, it would be excluded if an option to settle them by the entity’s own equity instruments if compound financial instruments is met the definition of equity instruments and recognized separately from the liability. The amendments should be applied for annual periods beginning on or after January 1, 2024, and earlier application is permitted. The Group is in review for the impact of these amendments on the consolidated financial statements.

•	Korean IFRS 1001 Presentation of Financial Statements – Disclosure of Accounting Policies<br>

The amendments to Korean IFRS 1001 define and require entities to disclose their material accounting policies. The IASB amended IFRS Practice Statement 2 Disclosure of Accounting Policies to provide guidance on how to apply the concept of materiality to accounting policy disclosures. The amendments should be applied for annual periods beginning on or after January 1, 2023, and earlier application is permitted. The Group is in review for the impact of these amendments on the consolidated financial statements.

•	Korean IFRS 1008 Accounting Policies, Changes in Accounting Estimates and Errors – Definition ofAccounting Estimates

The amendments define accounting estimates and clarify how to distinguish them from changes in accounting policies. The amendments should be applied for annual periods beginning on or after January 1, 2023, and earlier application is permitted. The Group does not expect that these amendments have a significant impact on the consolidated financial statements.

•	Korean IFRS 1012 Income Taxes – Deferred Tax Related to Assets and Liabilities Arising From a SingleTransaction

The amendments include an additional condition to the exemption to initial recognition of an asset or liability that a transaction does not give rise to equal taxable and deductible temporary differences at the time of the transaction. The amendments should be applied for annual periods beginning on or after January 1, 2023, and earlier application is permitted. The Group is in review for the impact of these amendments on the consolidated financial statements.

•	Korean IFRS 1001 Presentation of Financial Statements–Disclosure of Gain or Loss on Valuation ofFinancial Liabilities Subject to Adjustment of Exercise Price

If the entire or a part of financial instrument, whose exercise price is subject to change due to the issuer’s share price, is classified as a financial liability, the carrying amount of the financial liability and related gains and losses shall be disclosed. The amendments should be applied for annual periods beginning on or after January 1, 2023, and earlier application is permitted. The Group does not expect that these amendments have a significant impact on the consolidated financial statements.

2.3	Consolidation

The Group has prepared the consolidated financial statements in accordance with Korean IFRS 1110 Consolidated 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 any non-controlling interest in the acquired entity on an acquisition-by-acquisition basis either at fair value or at the non-controlling interest’s proportionate share of the acquired entity’s net identifiable assets. All other non-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 any non-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 among 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 loss of control

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

KT Corporation and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2022 and 2021

(c)	Disposal of subsidiaries

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

(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 arrangements

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 35). 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 Controlling Company’s functional and presentation currency.

KT Corporation and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2022 and 2021

(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 financial instruments 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 expense’.

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 on non-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 on non-monetary assets, such as equities classified as available-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.

KT Corporation and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2022 and 2021

(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.

Financial assets 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<br>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<br>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<br>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<br>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<br>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<br>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<br>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<br>loss and presented net in the statement of profit or loss within ‘finance income’ or ‘finance costs’ in the period in which it arises.
---	---

Notes to the Consolidated Financial Statements

December 31, 2022 and 2021

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. Dividend income from such investments continue to be recognized in profit or loss as ‘finance income’ when the Group’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 (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.

Notes to the Consolidated Financial Statements

December 31, 2022 and 2021

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 treatment 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<br>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 38.

The full fair value of a hedging derivative is classified as a non-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. A non-derivative financial asset and a non-derivative financial liability is classified as a current or non-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 to the limit of the cumulative change in fair value (present value) of the hedge item (the present value of the cumulative change in the future expected cash flows of the hedged item) from the inception of the hedge. 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 a non-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.

December 31, 2022 and 2021

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 treatment for trade receivables and Note 2.6 (c) for a description of the Group’s accounting policy on impairment.

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 inventories in-transit.

2.10	Non-Current Assets Held-for-Sale

Non-current assets (or disposal groups) 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<br><br><br>(Telecommunications equipment and others)		2 – 40 years
Vehicles		4 – 10 years
Tools		2 – 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.

Notes to the Consolidated Financial Statements

December 31, 2022 and 2021

2.12	Investment Property

Real estate held for rental income or investment gains is classified as investment property and right-of-use asset. 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 5 to 40 years.

2.13	Intangible Assets
(a)	Goodwill
---	---

Goodwill is measured as explained in Note 2.3 (a) and goodwill arising from acquisition of subsidiaries and businesses is 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 businesses 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.

(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), subscription rights, broadcast license, facility-use rights, and transportation rights that have 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	3 – 7 years
Software	3 – 7 years
Frequency usage rights	5 –10 years
Others^1^	1 – 50 years
^1^	Membership rights (condominium membership and golf membership), subscription rights, broadcast license,<br>facility usage rights and transportation 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 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.

December 31, 2022 and 2021

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 deferred and are presented as a credit in the statement of profit or loss within ‘other income’.

2.16	Impairment of Non-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 Group 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 on non-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 classifies non-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 and other payables’, ‘borrowings’ and ‘other financial liabilities’ in the statement of financial position.

Notes to the Consolidated Financial Statements

December 31, 2022 and 2021

Borrowings are initially recognized as the amount obtained by subtracting the transaction cost incurred from the fair value and is then measured as amortized cost. The difference between the consideration received (net of transaction cost) and the redemption amount is recognized as profit or loss over the period using the effective interest rate method. Fees paid to receive the borrowing limit are recognized as transaction costs for loans to the extent that they are likely to be borrowed as part or all of the borrowing limit. In this case, the fee will be deferred until the draw-down occurs. There is a high possibility that borrowings will be executed as part or all of the borrowing limit agreement (relevant fees to the extent that there is no evidence) are recognized as assets as advance payments for liquidity services and amortized over the relevant borrowing limit period.

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.

Borrowings are classified as current liabilities unless the Group has an unconditional right to defer settlement of the liability for at least 12 months after the reporting period.

(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 any non-cash assets transferred or liabilities assumed) is recognized in profit or loss.

The Group’s financial liabilities at fair value through profit or loss are financial instruments held for trading and financial liabilities designated as at fair value through profit or loss. A financial liability is held for trading if it is incurred principally for the purpose of repurchasing in the near term. A derivative that is not a designated as hedging instruments and an embedded derivative that is separated are also classified as held for trading. Financial liabilities designed as at fair value through profit or loss are structured financial liabilities containing embedded derivatives issued by the Group.

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 the following amount, and the related liability is recognized as ‘other financial liabilities’ in the consolidated statement of financial position:

•	the amount determined in accordance with the expected credit loss model under Korean IFRS 1109 FinancialInstruments
•	the amount initially recognized less, where appropriate, the cumulative amount of income recognized in accordance<br>with Korean IFRS 1115 Revenue from Contracts with Customers

December 31, 2022 and 2021

2.20	Compound Financial Instruments

Compound financial instruments are convertible notes that can be converted into equity instruments at the option of the holder.

The liability component of a compound financial instrument is recognized initially at the fair value of a similar liability that does not have an equity conversion option, and subsequently measured at amortized cost until extinguished on conversion or maturity of the bonds. The equity component is recognized initially on the difference between the fair value of the compound financial instrument as a whole and the fair value of the liability component. Any directly attributable transaction costs are allocated to the liability and equity components in proportion to their initial carrying amounts.

2.21	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.

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.

Notes to the Consolidated Financial Statements

December 31, 2022 and 2021

(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.

2.22	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 the non-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.

The acquiree may have outstanding share-based payment transactions that the acquirer does not exchange for its share-based payment transactions. If vested, those acquiree share-based payment transactions are part of the non-controlling interest in the acquiree and are measured at their market-based measure. If unvested, the market-based measure of unvested share-based payment transactions is allocated to the non-controlling interest on the basis of the ratio of the portion of the vesting period completed to the greater of the total vesting period and the original vesting period of the share-based payment transaction. The balance is allocated to post-combination service.

2.23	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.

2.24	Leases
(a)	Lessee
---	---

The Group leases various repeater server racks, offices, communication line facilities, machinery, cars, and others.

Contracts may contain both lease and non-lease components. The Group allocates the consideration in the contract to the lease and non-lease components based on their relative stand-alone prices.

KT Corporation and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2022 and 2021

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 (including in-substance fixed payments), less any lease<br>incentives receivable
•	Variable lease payment that are based on an index or a rate, initially measured using the index or rate as at the<br>commencement date
---	---
•	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,<br>and
---	---
•	Payments of penalties for terminating the lease, if the lease term reflects the Group (the lessee) exercising<br>that option
---	---

Measurement of lease liability also includes payments to be made in optional periods if the lessee is reasonably certain to exercise an option to extend the lease.

The Group determines the lease term as the non-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 the right-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:

•	the amount of the initial measurement of lease liability
•	any lease payments made at or before the commencement date less any lease incentives received<br>
---	---
•	any initial direct costs (leasehold deposits)
---	---
•	restoration costs
---	---

KT Corporation and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2022 and 2021

The right-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, the right-of-use asset is depreciated over the underlying asset’s useful life.

Payments associated with short-term leases and leases of low-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 vehicles, machinery, and others. Low-value assets are comprised of tools, office 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.

(c)	Extension and termination option

Extension and termination options are included in a number of property and equipment leases across the Group. These terms are used to maximize operational flexibility in terms of managing contracts. The majority of extension and termination options held are exercisable only by the Group and not by the respective lessor. Information on critical accounting estimates and assumptions related to the determination of the lease term is presented in Note 3.

2.25	Share Capital

The Controlling Company 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.

2.26	Revenue Recognition
(a)	Identifying performance obligations
---	---

The Group mainly provides telecommunication services and sells handsets. The Group identifies performance obligations with a customer such as providing telecommunication services, selling handsets, and others. 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.

KT Corporation and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2022 and 2021

(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.

(c)	Incremental contract acquisition costs

The Group pays commission fees when new customers subscribe to 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.

2.27	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 current income tax expense is measured at the amount expected to be paid to 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 positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation, and considers whether it is probable that a taxation authority will accept an uncertain tax treatment. The Group measures its tax balances either based on the most likely amount or the expected value, depending on which method provides a better prediction of the resolution of the uncertainty.

KT Corporation and Subsidiaries

Notes to the Consolidated Financial Statements

December 31, 2022 and 2021

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.

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.

2.28	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.

2.29	Approval on Issuance of the Consolidated Financial Statements

The consolidated financial statements of 2022 were approved for issuance by the Board of Directors on February 9, 2023 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 actual results, it poses significant risk of resulting in a material adjustment.

Estimates and assumptions that have significant risks 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 or value-in-use calculations to assess non-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 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 forRecirculation 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 increase, there is 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 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 38).

3.4	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).

Notes to the Consolidated Financial Statements

December 31, 2022 and 2021

3.5	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.

3.6	Critical Judgments in Determining the Lease Term

In determining the lease term, management considers all facts and circumstances that create an economic incentive to exercise an extension option, or not exercise a termination option. Extension options (or periods after termination options) are only included in the lease term if the lease is reasonably certain to be extended (or not terminated).

For leases of property, machinery, and communication line facilities, the following factors are normally the most relevant:

•	If there are significant penalties to terminate (or not extend), the Group is typically reasonably certain to<br>extend (or not terminate).
•	If any leasehold improvements are expected to have a significant remaining value, the Group is typically<br>reasonably certain to extend (or not terminate).
---	---
•	Otherwise, the Group considers other factors including historical lease durations and the costs and business<br>disruption required to replace the leased asset.
---	---

Most extension options in offices, retail stores and vehicles leases have not been included in the lease liability, because the Group can replace the assets without significant cost or business disruption.

The lease term is reassessed if an option is actually exercised (or not exercised) or the Group becomes obliged to exercise (or not exercise) it. The assessment of reasonable certainty is only revised if a significant event or a significant change in circumstances occurs, which affects this assessment, and that is within the control of the lessee.

The fair values of trade and other receivables with original maturities less than one year are equal to their carrying amounts because the discounting effect is immaterial. The fair value of trade and other receivables with original maturities longer than one year, which are mainly from sales of goods, is determined by discounting the expected future cash flow at the weighted average interest rate.

The carrying amount of membership rights with an indefinite useful life not subject to amortization, except for goodwill, is ~~W~~ 210,114 million as at December 31, 2022 (December 31, 2021: ~~W~~ 219,204 million).

Goodwill is allocated to the Group’s cash-generating unit, which is identified by operating segments. As at December 31, 2022, goodwill allocated to each cash-generation unit is as follows:

(In millions of Korean won)
Cash-Generating Unit	Amount
Mobile services	~~W~~	65,057
BC Card Co., Ltd.^^		41,234
HCN Co., Ltd.		228,674

Epsilon Global Communications Pte. Ltd.		160,033
KT MOS Bukbu Co., Ltd. and others		50,124
	~~W~~	708,224

The recoverable amount of goodwill has been determined based on the fair value obtained by calculating the value in use or deducting the cost of disposal. The pre-tax cash flow estimate was used to calculate the value of use based on the financial budget, such as the budget for the next five years. Cash flows after the estimated period were estimated using the expected growth rate, and the growth rate does not exceed the long-term average growth rate of the industry to which the cash-generating unit belongs. The Group determines the growth margin rate based on past performance and expectations of future market changes. The Group has determined pre-tax cash flow estimates based on past earnings and market growth forecasts, and the discount rate used reflects the specific risks of related operations.

The pre-tax discount rates applied to the calculation of the value in use of major goodwill related to HCN Co., Ltd., Epsilon Global Communications Pte. Ltd., ICT, etc. are 10.14%, 9.74%, 8.48%, etc., and the permanent growth rates are 0.00%, 1.00%, 0.00%, etc., respectively.

As a result of the impairment evaluation of goodwill, the recoverable amount of HCN Co., Ltd. is ~~W~~ 228,674 million, less than the carrying amount, and the impairment loss of ~~W~~ 24,006 million is allocated in full to goodwill and recognized as other expenses.

Notes to the Consolidated Financial Statements

December 31, 2022 and 2021

Amounts recognized in the consolidated statement of profit or loss for the years ended December 31, 2022 and 2021, are as follows:

(in millions of Korean won)	2022			2021
Current service cost	~~W~~	238,068		~~W~~	249,125
Net interest cost		3,139			5,047
Changes due to settlements of plan		(701	)		(681	)
Transfer out		(15,102	)		(16,660	)
Total expenses	~~W~~	225,404		~~W~~	236,831

Principal actuarial assumptions used are as follows:

	December 31, 2022	December 31, 2021
Discount rate	5.05%	2.55%
Salary growth rate	5.15%	5.10%

The sensitivity of the defined benefit obligations as at December 31, 2022, to changes in the principal assumptions is:

(in percentage, in millions of Korean won)	Effect on defined benefit obligation
	Changes inassumption		Increase inassumption		Decrease inassumption
Discount rate		0.5% point		~~W~~ (108,725)	~~W~~	117,362
Salary growth rate		0.5% point		113,037		(105,541	)

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 analysis is based on changes in 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, 2023, are ~~W~~281,118 million.

Notes to the Consolidated Financial Statements

December 31, 2022 and 2021

The Group has an obligation to invest in Real Estate Investment Company No.167, a related party, and others according to the agreement. As at December 31, 2022, the Group is planning to make an additional investment of ~~W~~ 53,120 million.

As at December 31, 2022, the limit of the credit card contract provided by the Group to K Bank, Inc. is ~~W~~ 1,000 million (December 31, 2021: ~~W~~ 1,000 million).

37.	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.

(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, 2022 and 2021, if the foreign exchange rate had strengthened of 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<br><br><br>foreign exchange rate			Impact on profitbefore income tax^1^			Impact on equity
2022.12.31		+ 10	%	~~W~~	(5,841	)	~~W~~	(15,836	)

		- 10	%		3,433			(8,692	)
^1^	Computed with considering derivatives hedging effect applied by the Group to hedge foreign exchange risk of<br>liabilities in foreign currencies
---	---

The analysis above 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 significant financial assets and liabilities in foreign currencies as at December 31, 2022 and 2021, are as follows:

(iii)	Price risk

As at December 31, 2022 and 2021, the Group is exposed to equity securities price risk because the securities held by the Group are traded in active markets. If the stock index increased or 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)
2022.12.31	+ 10	%	~~W~~111,288		~~W~~113,948
	- 10	%	(111,288	)	(113,948	)
2021.12.31	+ 10	%	~~W~~2,000		~~W~~4,588
	- 10	%	(2,000	)	(4,588	)

The analysis above is based on the assumption that the equity index increased or decreased by 10% with all other variables held constant and all the Group’s marketable equity instruments moved according to the historical correlation with the index. Equity would increase or 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 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 changes in interest rates and financial costs.

As at December 31, 2022 and 2021, if the market interest rate had increased or 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)
2022.12.31	+ 100 bp	~~W~~635		~~W~~(2,045	)
	- 100 bp	(669	)	2,100
2021.12.31	+ 100 bp	~~W~~753		~~W~~5,549
	- 100 bp	(731	)	(5,675	)

The analysis above 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 financial institutions with strong credit ratings are accepted.

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 defaults 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 expected credit loss is immaterial.

Total	~~W~~	13,027,594	~~W~~	11,578,687

The Group is exposed to credit risk for financial guarantee contracts. As at December 31, 2022, the Group’s maximum exposure amount is ~~W~~ 26,206 million (2021: ~~W~~ 71,697 million).

(i)	Trade receivables at amortized costs

The Group applies a simplified method of recognizing the expected credit loss allowance, which uses lifetime expected credit loss for all trade 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, 2022. Meanwhile, the credit sales assets of BC Card Co., Ltd., a subsidiary, were judged to have low credit risk, so the expected 12-month credit loss was applied.

(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 considers ‘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.

Details of changes in provisions for impairment of other financial assets at amortized costs for the years ended December 31, 2022 and 2021, are as follows:

Financial assets at fair value through other comprehensive income include available-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.

(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.

The debt-to-equity ratios as at December 31, 2022 and 2021, are as follows:

(in millions of Korean won)	December 31,2022			December 31,2021
Total liabilities	~~W~~	22,565,958		~~W~~	20,592,180
Total equity		18,414,723			16,567,161
Debt-to-equity ratio		123	%		124	%

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 consolidated statement of financial position plus net debt.

The gearing ratios as at December 31, 2022 and 2021, are as follows:

(in millions of Korean won)	December 31,2022			December 31,2021

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

(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, 2022 and 2021, are as follows:

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 separate financial statements of KT Corporation (the Company), which comprise the separate statements of financial position as at December 31, 2022 and 2021, 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, 2022 and 2021, 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 of December 31, 2022, based on Conceptual Framework for Designing and Operating Internal Control over Financial Reporting, and our report dated March 8, 2023 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.

Cash-Generating Unit Impairment Assessment

•	Why the matter was determined to be a key audit matter

As described in Note 2.14 and Note 12 in the separate financial statements, the Company assesses whether indicators of impairment on assets exist at the end of every reporting period in accordance with Korean IFRS 1036 Impairment of Assets, and tests for impairment whenever there is an impairment indicator. Given that there is a significant difference between the market value of the Company and the total net assets of the Company, the Company determined that indicators of impairment on the cash-generating units (“CGUs”) with respect to the wire, wireless, and corporate business existed as at December 31, 2022. 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 separate financial statements. Management’s assumptions have a significant impact on determining the recoverable amounts. This results in a high degree of judgment, 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.

•	How the matter was addressed in the audit:

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<br>relevant internal controls.
•	We obtained an understanding of the Company’s procedures to identify the CGUs and evaluated relevant<br>internal controls.
---	---
•	We evaluated the appropriateness of valuation models used by management to estimate the recoverable amounts.<br>
---	---
•	We evaluated the appropriateness of internal and external information used by management to estimate the<br>recoverable amounts.
---	---
•	We assessed the consistency of key assumptions used by management to estimate the recoverable amounts, by<br>comparing the historical results, current market conditions and future business plans.
---	---
•	We evaluated the qualifications and independence of management’s external experts.
---	---

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 withGovernance 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<br>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<br>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<br>appropriate in the circumstances.
---	---
•	Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and<br>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.

•

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.

---

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 is Ho-Sung Han, 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.

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

The preparation of the separate financial statement 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, 2022.

•	Amendments to Korean IFRS 1001 Presentation of Financial Statements – Classification of Liabilities asCurrent or Non-Current

KT Corporation

Notes to the Separate Financial Statements

December31, 2022 and 2021

The amendments clarify that liabilities are classified as either current or non-current, depending on the substantive rights that exist at the end of the reporting period. Classification is unaffected by the likelihood that an entity will exercise right to defer settlement of the liability or the expectations of management. Also, the settlement of liability includes the transfer of the entity’s own equity instruments, however, it would be excluded if an option to settle them by the entity’s own equity instruments if compound financial instruments is met the definition of equity instruments and recognized separately from the liability. The amendments should be applied for annual periods beginning on or after January 1, 2023, and earlier application is permitted. The Company is in review for the impact of these amendments on the separate financial statements.

•	Korean IFRS 1001 Presentation of Financial Statements – Disclosure of Accounting Policies<br>

The amendments to Korean IFRS 1001 define and require entities to disclose their material accounting policies. The amendments should be applied for annual periods beginning on or after January 1, 2023, and earlier application is permitted. The Company is in review for the impact of these amendments on the separate financial statements.

•	Korean IFRS 1008 Accounting Policies, Changes in Accounting Estimates and Errors – Definition ofAccounting Estimates

The amendments define accounting estimates and clarify how to distinguish them from changes in accounting policies. The amendments should be applied for annual periods beginning on or after January 1, 2023, and earlier application is permitted. The Company does not expect that these amendments have a significant impact on the separate financial statements.

•	Korean IFRS 1012 Income Taxes – Deferred Tax Related to Assets and Liabilities Arising From aSingle Transaction

The amendments include an additional condition to the exemption to initial recognition of an asset or liability that a transaction does not give rise to equal taxable and deductible temporary differences at the time of the transaction. The amendments should be applied for annual periods beginning on or after January 1, 2023, and earlier application is permitted. The Company does not expect that these amendments have a significant impact on the separate financial statements.

•	Korean IFRS 1001 Presentation of Financial Statements – Disclosure of Gain or Loss on Valuation ofFinancial Liabilities Subject to Adjustment of Exercise Price

If the entire or a part of financial instrument, whose exercise price is subject to change due to the issuer’s share price, is classified as a financial liability, the carrying amount of the financial liability and related gains and losses shall be disclosed. The amendments should be applied for annual periods beginning on or after January 1, 2023, and earlier application is permitted. The Company does not expect that these amendments have a significant impact on the separate financial statements.

KT Corporation

Notes to the Separate Financial Statements

December31, 2022 and 2021

2.3	Subsidiaries, Associates and Joint Ventures

The financial statements of the Company are the separate financial statements prepared in accordance with Korean IFRS 1027 SeparateFinancial Statements. Investments in subsidiaries, joint ventures and associates are recognized at cost under the direct equity method. Management applied the carrying amounts under the previous K-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

KT Corporation

Notes to the Separate Financial Statements

December31, 2022 and 2021

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.

(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.

KT Corporation

Notes to the Separate Financial Statements

December31, 2022 and 2021

•	Fair value through other comprehensive income: Assets that are held for collection of contractual cash flows and<br>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<br>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<br>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<br>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<br>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<br>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 instrument
---	---

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. Dividend income from such investments continue to be recognized in profit or loss as ‘finance income’ when the Company’s right to receive payments is established.

(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.

KT Corporation

Notes to the Separate Financial Statements

December31, 2022 and 2021

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

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 treatment 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<br>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 a non-current asset or non-current 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. A non-derivative financial asset and a non-derivative financial liability is classified as a current or non-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)’.

KT Corporation

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 treatment for trade receivables and Note 2.5 (c) for a description of the Company’s accounting policy on impairment.

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 inventories in-transit.

2.9	Property and Equipment

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

KT Corporation

Notes to the Separate Financial Statements

December31, 2022 and 2021

2.10	Investment Property

Real estate held for rental income or investment gains is classified as investment property and right—of-use asset. 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.

2.11	Intangible Assets
(a)	Goodwill
---	---

Goodwill represents the excess of the aggregate of the consideration transferred, the amount of any non-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.

(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 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
Others^1^	2 – 50 years
^1^	Membership rights (condominium membership and golf membership) included in others are classified as intangible<br>assets with indefinite useful life.

KT Corporation

Notes to the Separate Financial Statements

December31, 2022 and 2021

2.12	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.

2.13	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 deferred and presented as a credit in the statement of profit or loss within ‘other income’.

2.14	Impairment of Non-Financial Assets

Goodwill and intangible assets that have an indefinite useful life are not subject to amortization and are tested annually for impairment, or more frequently if events or changes in circumstances indicate that they might be impaired. The Company estimates the recoverable amount for each asset, and, in cases when the recoverable amount cannot be estimated for an individual 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 on non-financial assets other than goodwill are evaluated for reversal at the end of each reporting period.

2.15	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.

2.16	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 classifies non-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 and other payables’, ‘borrowings’, and ‘other financial liabilities’ in the statement of financial position.

Borrowings are is initially recognized as the amount obtained by subtracting the transaction cost incurred from the fair value and is then measured as amortized cost. The difference between the consideration received (net of transaction cost) and the redemption amount is recognized as profit or loss over the period using the effective interest rate method. Fees paid to receive the borrowing limit are recognized as transaction costs for loans to the extent that they are likely to be borrowed as part or all of the borrowing limit. In this case, the fee will be deferred until draw-down occurs. There is a high possibility that borrowings will be executed as part or all of the borrowing limit agreement (relevant fees to the extent that there is no evidence) are recognized as assets as advance payments for liquidity services and amortized over the relevant borrowing limit period.

Borrowings are classified as current liabilities unless the Company has an unconditional right to defer settlement of the liability for at least 12 months after the reporting period.

Notes to the Separate Financial Statements

December31, 2022 and 2021

The Company’s financial liabilities at fair value through profit or loss are financial instruments held for trading and financial liabilities designated as at fair value through profit or loss. A financial liability is held for trading if it is incurred principally for the purpose of repurchasing in the near term. A derivative that is not a designated as hedging instruments and an embedded derivative that is separated are also classified as held for trading. Financial liabilities designed as at fair value through profit or loss are structured financial liabilities containing embedded derivatives issued by the Company.

2.17	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.

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.

December31, 2022 and 2021

(c)	Long-term employee benefits

Certain entities within the Company provide long-term employee benefits that are entitled to employees with service period at least five 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.

2.18	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 the non-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.

2.19	Provisions

Provisions for service warranties, make good obligation, and legal claims are recognized when the Company has a present legal or constructive obligation as a result of past events, 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.

2.20	Leases
(a)	Lessee
---	---

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

Contracts may contain both lease and non-lease components. The Company allocates the consideration in the contract to the lease and non-lease components based on their relative stand-alone prices.

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 (including in-substance fixed payments), less any lease<br>incentives receivable
•	Variable lease payment that are based on an index or a rate, initially measured using the index or rate as at the<br>commencement date
---	---
•	Amounts expected to be payable by the Company (the lessee) under residual value guarantees
---	---

KT Corporation

Notes to the Separate Financial Statements

December31, 2022 and 2021

•	The exercise price of a purchase option if the Company (the lessee) is reasonably certain to exercise that<br>option, and
•	Payments of penalties for terminating the lease, if the lease term reflects the Company (the lessee) exercising<br>that option
---	---

Measurement of lease liability also includes payments to be made in optional periods if the lessee is reasonably certain to exercise an option to extend the lease.

The Company determines the lease term as the non-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 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 the right-of-use asset.

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

•	the amount of the initial measurement of lease liability
•	any lease payments made at or before the commencement date less any lease incentives received<br>
---	---
•	any initial direct costs
---	---
•	restoration costs
---	---

The right-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, the right-of-use asset is depreciated over the underlying asset’s useful life.

KT Corporation

Notes to the Separate Financial Statements

December31, 2022 and 2021

(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.

(c)	Extension and termination options

Extension and termination options are included in a number of property and equipment leases across the Company. These terms are used to maximize operational flexibility in terms of managing contracts. The majority of extension and termination options held are exercisable only by the Company and not by the respective lessor. Information on critical accounting estimates and assumptions related to the determination of the lease term is presented in Note 3.

2.21	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.

2.22	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 others. 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.

KT Corporation

Notes to the Separate Financial Statements

December31, 2022 and 2021

(c)	Incremental contract acquisition costs

The Company pays commission fees when new customers subscribe to 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.

2.23	Current and Deferred Tax

Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation, and considers whether it is probable that a taxation authority will accept an uncertain tax treatment. The Company measures its tax balances either based on the most likely amount or the expected value, depending on which method provides a better prediction of the resolution of the uncertainty.

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.

2.24	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.

2.25	Approval on Issuance of the Separate Financial Statements

The separate financial statements of 2022 were approved for issuance by the Board of Directors on February 9, 2023 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 actual results, it poses significant risk of resulting in a material adjustment.

3.1	Impairment of Non-Financial Assets (including Goodwill)

The Company determines the recoverable amount of a cash generating unit (CGU) based on fair value or value-in-use calculations to assess non-financial assets (including goodwill) for impairment (Notes 12 and 13).

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 29).

If certain portion of the taxable income is not used for investments or increase in wages or dividends in accordance with the Tax System forRecirculation 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 increase, there is uncertainty in measuring the final tax effects.

KT Corporation

Notes to the Separate Financial Statements

December31, 2022 and 2021

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 36).

3.4	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 17).

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

3.6	Critical Judgements in Determining the Lease Term

For leases of properties, machinery, and communication line facilities, the following factors are normally the most relevant:

•	If there are significant penalties to terminate (or not extend), the Company is typically reasonably certain to<br>extend (or not terminate).
•	If any leasehold improvements are expected to have a significant remaining value, the Company is typically<br>reasonably certain to extend (or not terminate).
---	---
•	Otherwise, the Company considers other factors including historical lease durations and the costs and business<br>disruption required to replace the leased asset.
---	---

The lease term is reassessed if an option is actually exercised (or not exercised) or the Company becomes obliged to exercise (or not exercise) it. The assessment of reasonable certainty is only revised if a significant event or a significant change in circumstances occurs, which affects this assessment, and that is within the control of the lessee.

The fair values of trade and other receivables with original maturities less than one year are equal to their carrying amount because the discounting effect is immaterial. The fair value of trade and other receivables with original maturities longer than one year, which are mainly from sales of goods, is determined by discounting the expected future cash flow at the weighted average interest rate.

Notes to the Separate Financial Statements

December31, 2022 and 2021

The Company annually performs an assessment of goodwill impairment. The recoverable amount of all CGUs has been determined based on value-in-use. These calculations use cash flow projections based on financial budgets approved by management covering a five-year period. Cash flows beyond the five-year period are extrapolated using the estimated growth rates of 0%. The growth rate does not exceed the long-term average growth rate included in industry report specific to the industry in which the CGU operates.

The Company determines the gross margin rate based on past performance and its expectations of market changes. The average growth rates used are estimated based on historical growth rate. In addition, the Company estimated pre-tax cash flow based on past performance and its expectation of market growth. The discount rate applied is pre-tax discount rate of 8.48%, reflecting specific risks related to the relevant CGUs.

As a result of impairment tests, the Company concluded that the carrying amount of CGUs does not exceed the recoverable amount of CGUs. Therefore, the Company did not recognize any impairment loss on goodwill for the years ended December 31, 2022 and 2021.

The sensitivity analysis of the defined benefit obligations as at December 31, 2022, to changes in the principal assumptions, is as follows:

(in millions of Korean won)	Effect on defined benefit obligation
	Changes inassumption			Increase inassumption		Decrease inassumption
Discount rate		0.50	%p	~~W~~	(37,672)	~~W~~	39,718
Future salary growth rate		0.50	%p		35,532		(34,035	)

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 analysis are based on changes in 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 Company reviews the funding level on an annual basis and has a policy of eliminating deficit from the fund. Expected contributions to post-employment benefit plans, for the year ending December 31, 2023, are ~~W~~ 106,752 million.

The expected maturity analysis of undiscounted pension benefits as at December 31, 2022, is as follows:

(in millions of Korean won)	Less than<br><br><br>1 year		Between 1-2years		Between 2-5years		Over 5 years		Total
Pension benefits	~~W~~	125,271	~~W~~	239,316	~~W~~	613,973	~~W~~	1,056,612	~~W~~	2,035,172

The weighted average duration of the defined benefit obligations is 5.4 years.

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.

As at December 31, 2022 and 2021, if the foreign exchange rate had strengthened or 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 foreignexchange rate			Impact on profitbefore income tax ^1^			Impact on equity

(iii)	Price risk

As at December 31, 2022 and 2021, the Company is exposed to equity securities price risk because the securities held by the Company are traded in active markets. If the increased or 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)			Impact on profitbefore tax			Impact on equity
2022.12.31	+ 10	%	~~W~~	—		~~W~~	112,222
	- 10	%		—			(112,222	)
2021.12.31	+ 10	%	~~W~~	20		~~W~~	3,285
	- 10	%		(20	)		(3,285	)

The analysis above is based on the assumption that the equity index increased or decreased by 10% with all other variables held constant and all the Company’s marketable equity instruments moved according to the historical correlation with the index. Equity would increase or 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 changes in interest rates and financial costs.

As at December 31, 2022 and 2021, if the market interest rate increased or 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)		Impact on profitbefore tax			Impact on equity
2022.12.31	+ 100 bp	~~W~~	(30	)	~~W~~	(2,338	)

	- 100 bp		4			(5,446	)

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.

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.

KT Corporation

Notes to the Separate Financial Statements

December31, 2022 and 2021

•	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 defaults 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 expected credit loss is immaterial.

The maximum exposure to credit risk of the Company’s financial instruments without considering the value of collaterals as at December 31, 2022 and 2021, are as follows:

(in millions of Korean won)	December 31, 2022		December 31, 2021

(i)	Trade receivables at amortized costs

The Company applies the simplified approach to measuring expected credit loss allowance, which uses lifetime expected credit loss for all trade receivables at amortized costs.

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, 2022.

The expected credit losses reflect forward-looking information. Provision for impairment as at December 31, 2022 and 2021, are as follows:

(in millions of Korean won)	December 31, 2022
	Less than<br><br><br>6 months			7-12 months			More than<br><br><br>1 years			Total

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

The Company is also exposed to credit risk in relation to cash equivalents. The maximum exposure, as at December 31, 2022, 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 considers ‘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.

Details of changes in provisions for impairment the years ended December 31, 2022 and 2021, are as follows:

(in millions of Korean won)	2022			2021

(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’s debt-to-equity ratios as at December 31, 2022 and 2021, are as follows:

(in millions of Korean won)	December 31, 2022			December 31, 2021
Total liabilities	~~W~~	15,559,694		~~W~~	15,497,475
Total equity		14,858,080			13,864,894
Debt-to-equity<br>ratio		105	%		112	%

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 separate statement of financial position plus net debt.

The Company’s gearing ratios as at December 31, 2022 and 2021, are as follows:

(in millions of Korean won)	December 31, 2022			December 31, 2021

(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.

Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

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 ofInternal 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 is Ho-Sung Han, Certified Public Accountant.
