Report of Independent Registered Public Accounting Firm
To the Board of Directors and Stockholders of KT Corporation
Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated statements of financial position of KT Corporation and its subsidiaries (the “Company”) as of December 31, 2024 and 2023, the related consolidated statements of profit or loss, comprehensive income, changes in equity, and cash flows, for each of the two years in the period ended December 31, 2024, and the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2024, based on criteria established in 
Internal Control—Integrated Framework (2013)
 issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2024, in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on criteria established in
Internal Control—Integrated Framework (2013) 
issued by COSO.
Basis for Opinions
The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting included in Item 15. Our responsibility is to express an opinion on the Company’s consolidated financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.
Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audits of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for

Table of Contents
external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current-period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Mobile services revenue and handset revenue for mobile services (“Mobile revenue”) – Refer to Notes 2 and 25 to the consolidated financial statements
Critical Audit Matter Description
As described in Note 2.24 to the consolidated financial statements, the Company recognizes handset revenue for mobile services at the point in time when control of the handset is transferred to the customer. The Company recognizes telecommunication services revenue over the estimated periods of each service by transferring promised services to customers. Due to the large volume of low-dollar transactions with customers, the Company needs complex and elaborate information technology systems to accurately record mobile revenue.
We identified the occurrence and accuracy of mobile revenue as a critical audit matter given the magnitude and complexity of mobile revenue recorded in the billing system of the Company, which required the involvement of professionals with expertise in information technology (IT) necessary for us to identify and test the Company’s billing system used in processing the mobile revenue transactions.
How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to the Company’s mobile revenue transactions included the following, among others:
 
 
 
We obtained an understanding of the Company’s information system and business processes, relevant to mobile revenue.
 
 
 
With the assistance of our IT specialists, we identified the relevant systems used to process mobile revenue and tested the relevant general information technology controls.
 
 
 
We reconciled the mobile revenue in the billing system with the revenue in the ledger.
 
 
 
We developed an expectation of mobile services revenue amounts using historical service revenue and subscriber information and compared it to the recorded amount.
 
F-3

Table of Contents
 
 
We performed tests of the control activities addressing the accuracy and completeness of the subscriber information used in our audit procedures.
 
 
 
To verify the occurrence and accuracy of handset revenue for mobile services, we selected transactions from the sub-ledger, reconciled the selection with contractual terms between the Company and customers of the Company, and compared the billed amounts to receipts.

1
Sum of the interests owned by the Controlling Company and subsidiaries.
2
Although the Controlling Company owns less than 50% of the interest in
Nasmedia Co., Ltd., KTCS Corporation and KTIS Corporation, Millie Seojae, and GENIE Music Corporation, these entities are consolidated as the Controlling Company can exercise the majority of voting rights in its decision-making process at all times, based on voting patterns at previous shareholders’ meetings.
3
Although the Controlling Company owns less than 50% interest in
K-Realty
Qualified Private Real Estate Investment Trust No. 1, this entity is consolidated by comprehensively considering the criteria for determining control, such as ‘power’, ‘variable profit’, and ‘relationship between power and variable profit’, rather than simply judging by the interests owned by the Controlling Company.
4
The number of treasury stock held by subsidiaries are deducted from the total number of shares when calculating the controlling percentage interest.

Material 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 consolidated financial statements of the Group have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”).
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 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 and interpretations adopted by the Group
The Group has the following standards and interpretations for the first time for their annual reporting period commencing January 1, 2024.
- IAS 1
Presentation of Financial Statements
(Amendment in 2020) – Classification of Liabilities as Current or
Non-current
The amendments clarify that the classification of liabilities as current or
non-current
is based on rights that are in existence at the end of the reporting period, specify that classification is unaffected by expectations about whether an entity will exercise its right to defer settlement of a liability, explain that rights are in existence if covenants are complied with at the end of the reporting period, and introduce a definition of ‘settlement’ to make clear that settlement refers to the transfer to the counterparty of cash, equity instruments, other assets or services.
- IAS 1
Presentation of Financial Statements
Non-current
Liabilities with Covenants (Amendment)
The amendments specify that only covenants that an entity is required to comply with on or before the end of the reporting period affect the entity’s right to defer settlement of a liability for at least twelve months after the reporting date.
The amendments also specifies that the right to defer settlement of a liability for at least twelve months after the reporting date is not affected if an entity only has to comply with a covenant after the reporting period. However, if the entity’s right to defer settlement of a liability is subject to the
 
F-22

Table of Contents
KT Corporation and Subsidiaries
Notes to the Consolidated Financial Statements
December 31, 2022, 2023 and 2024
 
 
entity complying with covenants within twelve months after the reporting period, an entity discloses information that enables users of financial statements to understand the risk of the liabilities becoming repayable within twelve months after the reporting period. This would include information about the covenants (including the nature of the covenants and when the entity is required to comply with them), the carrying amount of related liabilities and facts and circumstances, if any, that indicate that the entity may have difficulties complying with the covenants.
- IAS 7
Statement of Cash Flows
and IFRS 17
Financial Instruments
: Disclosures – Supplier Finance Arrangements (Amendment)
The amendments add a disclosure objective to IAS 7 stating that an entity is required to disclose information about its supplier finance arrangements that enables users of financial statements to assess the effects of those arrangements on the entity’s liabilities and cash flows. In addition, IFRS 17 was amended to add supplier finance arrangements as an example within the requirements to disclose information about an entity’s exposure to concentration of liquidity risk.
Note 19 provides the required disclosures related to these amendments.
- IFRS 16
Leases
– Lease Liability in a Sale and Leaseback (Amendment)
The amendments to IFRS 16 add subsequent measurement requirements for sale and leaseback transactions that satisfy the requirements in IFRS 15 Revenue from Contracts with Customers to be accounted for as a sale. The amendments require the seller-lessee to determine ‘lease payments’ or ‘revised lease payments’ such that the seller-lessee does not recognize a gain or loss that relates to the right of use retained by the seller-lessee, after the commencement date.
A seller-lessee applies the amendments retrospectively in accordance with IAS 8 to sale and leaseback transactions entered into after the date of initial application, which is defined as the beginning of the annual reporting period in which the entity first applied IFRS 16.
- IAS 1
Presentation of Financial Statements
– Disclosure of Virtual Assets (Amendment)
The amendments to IAS 1 add additional disclosure requirements required by other standards for transactions related to virtual assets, setting out disclosure requirement for each case of 1) holding virtual assets, 2) holding virtual assets on behalf of customer, and 3) issuing virtual assets.
When holding a virtual asset, disclosure on the general information about virtual assets, the accounting policy applied and each virtual asset’s acquisition method, cost and the fair value at the end of the reporting period is required. Also, when issuing a virtual asset, the entity’s obligations and status of fulfillment of the obligation related to the issued virtual asset, the timing and amount of the recognized revenue of the sold virtual asset, the number of virtual assets held after issuance, and important contract details shall be disclosed.
There is no significant impact of the amendments listed above on the consolidated financial statements.

(2) New and revised standards and interpretations in issue but not yet effective or adopted by the Group
At the date of authorization of these financial statements, the Group has not applied the following new and amended IFRS standards that have been issued but are not yet effective:
- IAS 21
The Effects of Changes in Foreign Exchange Rates
– Lack of Exchangeability
The amendments specify how to assess whether a currency is exchangeable, and how to determine the exchange rate when it is not.
The amendments state that a currency is exchangeable into another currency when an entity is able to obtain the other currency within a time frame that allows for a normal administrative delay and through a market or exchange mechanism in which an exchange transaction would create enforceable rights and obligations.
The amendments are effective for annual reporting periods beginning on or after January 1, 2025, with earlier application permitted. An entity is not permitted to apply the amendments retrospectively. Instead, an entity is required to apply the specific transition provisions included in the amendments.
- IFRS 9
Financial Instruments
and IFRS 7
Financial Instruments: Disclosures
– Classification and measurement requirements of financial instruments
The amendments clarify the conditions related to the discharge of a financial liability before the settlement date when settling such financial liabilities using an electronic payment system. They further specify an interest feature, a contingent feature, financial assets with
non-recourse
features and contractually linked instruments which should be considered in assessing whether contractual cash flows of a financial asset are consistent with a basic lending arrangement. Furthermore, the amendments include additional disclosure requirements for investments in equity instruments designated at fair value through other comprehensive income and contractual terms that could change the timing or amount of contractual cash flows. The amendments are applied retrospectively for annual reporting periods beginning on or after January 1, 2026 with earlier application permitted.
- IFRS 9 Financial Instruments – Derecognition of lease liabilities and Transaction price
The amendments clarify that when a lessee has determined that a lease liability has been extinguished in accordance with IFRS 9, the lessee is required to recognize any resulting gain or loss in profit or loss. Additionally, the amendments have replaced ‘their transaction price (as defined in IFRS 15)’ in IFRS 09:5.1.3 with ‘the amount determined by applying IFRS 15’ to remove an inconsistency between IFRS 9 and the requirements in IFRS 15.
The amendments are effective for annual reporting periods beginning on or after January 1, 2026, with earlier application permitted.
- IFRS 10 Consolidated Financial Statements – Determination of ‘de facto agent’
The amendments have amended IFRS 10:B74 to use less conclusive language and to clarify that the relationship described in IFRS 10:B74 is just one example of a circumstance in which judgement is required to determine whether a party is acting as a de facto agent.

The amendments are effective for annual reporting periods beginning on or after January 1, 2026, with earlier application permitted.
- IFRS 1 First-time adoption of International Financial Reporting Standards – Hedging accounting by a first-time adopter
The amendments have improved the consistency of the wording of IFRS 1:B6 with the requirements for hedge accounting in IFRS 9 and added cross-references to IFRS 9:6.4.1 to improve the understandability of IFRS 1.
The amendments are effective for annual reporting periods beginning on or after January 1, 2026, with earlier application permitted.
- IFRS 7 Financial Instruments: Disclosures – Gain or loss on derecognition
The amendments have updated the obsolete cross-reference in IFRS 7:B38 and aligned the wording of this paragraph with the terms used in IFRS.
The amendments are effective for annual reporting periods beginning on or after January 1, 2026, with earlier application permitted.
- IAS 7 Statement of Cash Flows: Cost method
The amendments have replaced the term ‘cost method’ with ‘at cost’ in IAS 7:37.
The amendments are effective for annual reporting periods beginning on or after January 1, 2026, with earlier application permitted.
- IFRS 18 Presentation and Disclosures in Financial Statements
IFRS 18 replaces IAS 1, carrying forward many of the requirements in IAS 1 unchanged and complementing them with new requirements. In addition, some IAS 1 paragraphs have been moved to IAS 8 and IFRS 7. Furthermore, IASB has made minor amendments to IAS 7 and IAS 33 Earnings per Share.
IFRS 18 introduces new requirements to:
 
 
 
present specified categories and defined subtotals in the statement of profit or loss;
 
 
 
provide disclosures on management-defined performance measures (MPMs) in the notes to the financial statements; and
 
 
 
improve aggregation and disaggregation.
An entity is required to apply IFRS 18 for annual reporting periods beginning on or after January 1, 2027, with earlier application permitted. The amendments to IAS 7 and IAS 33, as well as the revised IAS 8 and IFRS 7, become effective when an entity applies IFRS 18. IFRS 18 requires retrospective application with specific transition provisions.
The directors of the Company anticipate that the application of these amendments may have an impact on the Group’s consolidated financial statements in future periods.
The Group is reviewing the impact of the above-listed amendments on the consolidated financial statements.

2.3
Consolidation
The Group has prepared the consolidated financial statements in accordance with IFRS 10 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.
(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
 
F-26

Table of Contents
KT Corporation and Subsidiaries
Notes to the Consolidated Financial Statements
December 31, 2022, 2023 and 2024
 
 
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 34). 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 entities in the Group are measured using the currency of the primary economic environment in which each entity operates (its functional currency). The consolidated financial statements are presented in Korean won, which is the presentation currency for the consolidated financial statements.
(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.
 
F-27

KT Corporation and Subsidiaries
Notes to the Consolidated Financial Statements
December 31, 2022, 2023 and 2024
 
 
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.
(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.
 
F-28

KT Corporation and Subsidiaries
Notes to the Consolidated Financial Statements
December 31, 2022, 2023 and 2024
 
 
A. Debt instruments
Subsequent measurement of debt instruments depends on the Group’s business model for managing the asset and the cash flow characteristics of the asset. The Group classifies its debt instruments into one of the following three measurement categories:
 
  
Amortized cost: Assets that are held for collection of contractual cash flows where those cash flows represent solely payments of principal and interest are measured at amortized cost. A gain or loss on a debt investment that is subsequently measured at amortized cost and is not part of a hedging relationship is recognized in profit or loss when the asset is derecognized or impaired. Interest income from these financial assets is included in ‘finance income’ using the effective interest rate method.
 
 
Fair value through other comprehensive income: Assets that are held for collection of contractual cash flows and for selling the financial assets, where the assets’ cash flows represent solely payments of principal and interest, are measured at fair value through other comprehensive income. Movements in the carrying amount are taken through other comprehensive income, except for the recognition of impairment loss (and reversal of impairment loss), interest income and foreign exchange gains and losses which are recognized in profit or loss. When the financial asset is derecognized, the cumulative gain or loss previously recognized in other comprehensive income is reclassified from equity to profit or loss. Interest income from these financial assets is included in ‘finance income’ using the effective interest rate method. Foreign exchange gains and losses are presented in ‘finance income’ or ‘finance costs’ and impairment loss in ‘finance costs’ or ‘operating expenses’.
 
  
Fair value through profit or loss: Assets that do not meet the criteria for amortized cost or fair value through other comprehensive income are measured at fair value through profit or loss. A gain or loss on a debt investment that is subsequently measured at fair value through profit or loss and is not part of a hedging relationship is recognized in profit or loss and presented net in the statement of profit or loss within ‘finance income’ or ‘finance costs’ in the period in which it arises.
B. Equity instruments
The Group subsequently measures all equity investments at fair value. Where the Group’s management has elected to present fair value gains and losses on equity investments in other comprehensive income, there is no subsequent reclassification of fair value gains and losses to profit or loss following the derecognition of the investment. 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.
 
F-29

KT Corporation and Subsidiaries
Notes to the Consolidated Financial Statements
December 31, 2022, 2023 and 2024
 
 
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.
 
 
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 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 37.
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.
 
F-30

KT Corporation and Subsidiaries
Notes to the Consolidated Financial Statements
December 31, 2022, 2023 and 2024
 
 
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.
 
 
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(specific
identification method).
 
 
2.10
Property and Equipment
Property and equipment are stated at historical cost less accumulated depreciation and accumulated impairment losses. Historical cost includes expenditures that is directly attributable to the acquisition of the items.
Depreciation of all property and equipment, except for land, is calculated using the straight-line method to allocate their cost, net of their residual values, over their estimated useful lives as follows:
 
   
Useful Life
Buildings
  5 – 40 years
Structures
  5 – 40 years
Machinery and equipment
(Telecommunications equipment and others)
  2 – 40 years
Vehicles
  4 – 10 years
Tools
  3 – 6 years
Office equipment
  2 – 10 years
 
F-31

KT Corporation and Subsidiaries
Notes to the Consolidated Financial Statements
December 31, 2022, 2023 and 2024
 
 
The depreciation method, residual values, and useful lives of property and equipment are reviewed at the end of each reporting period and, if appropriate, accounted for as changes in accounting estimates.
 
 
2.11
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.
 
 
2.12
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 – 10 years  
Software
   3 – 10 years  
Frequency usage rights
   5 – 10 years  
Others
1
   1 – 50 years  
 
 1
Membership rights (condominium membership and golf membership), subscription rights, broadcast license, facility usage rights and transportation license included in others are classified as intangible assets with indefinite useful life.
 
 
2.13
Borrowing Costs
General and specific borrowing costs that are directly attributable to the acquisition, construction or production of a qualifying asset are capitalized during the period of time that is required to

complete and prepare the asset for its intended use or sale. Investment income earned on the temporary investment of specific borrowings on qualifying assets is deducted from the borrowing costs eligible for capitalization. Other borrowing costs are expensed in the period in which they are incurred.
 
 
2.14
Government Grants
Grants from the government are recognized at their fair value where there is a reasonable assurance that the grant will be received and the 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’.

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.
 
 
2.16
Trade and Other Payables
Trade and other payables 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.
 
 
2.17
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 and other payables’, ‘borrowings’ and ‘other financial liabilities’ in the statement of financial position.
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.
 
 
2.18
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 IFRS 9 Financial Instruments
 
 
the amount initially recognized less, where appropriate, the cumulative amount of income recognized in accordance with IFRS 15 Revenue from Contracts with Customers

2.19
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.
(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.
 
 
2.20
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.
 
 
2.21
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.
 

 
2.22
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.
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 incentives receivable
 
  
Variable lease payment that are based on an index or a rate, initially measured using the index or rate as at the commencement date
 
  
Amounts expected to be payable by the Group (the lessee) under residual value guarantees
 
  
The exercise price of a purchase option if the Group (the lessee) is reasonably certain to exercise that option, and
 
  
Payments of penalties for terminating the lease, if the lease term reflects the Group (the lessee) exercising that option
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.
 
F-36

KT Corporation and Subsidiaries
Notes to the Consolidated Financial Statements
December 31, 2022, 2023 and 2024
 
 
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
 
  
any initial direct costs (leasehold deposits)
 
  
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 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.
 
 
2.23
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.
 
 
2.24
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 service by transferring promised services to customers.
(b) Allocation the transaction price and revenue recognition
The Group allocates the transaction price to each performance obligation identified in the contract based on a relative stand-alone selling prices of the goods or services being provided to the customer. To allocate the transaction price to each performance obligation on a relative stand-alone price basis, the Group determines the stand-alone selling price at contract inception of the distinct good or service underlying each performance obligation in the contract and allocates the transaction price on a relative stand-alone selling price basis. 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.
 
 
2.25
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.

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 for 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.
 
2.26
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.

Critical Accounting Estimates and Assumptions
The preparation of financial statements requires the Group to make estimates and assumptions about the future. Management also needs to exercise judgment in applying the Group’s accounting policies. Estimates and assumptions are evaluated continuously and are based on historical experience and other factors, including reasonable expectations of future events under the given circumstances. As it is rare for the results of accounting estimates to be identical to actual results, significant risks exist that may lead to material adjustments.
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 12, 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 29).
If a certain portion of the taxable income is not used for investments or increase in wages or dividends in accordance with the
Tax System for Recirculation of Corporate Income
,
the Group is liable to pay additional income tax calculated based on the tax laws. Accordingly, the measurement of current and deferred income tax is affected by the tax effects from the new tax system. As the Group’s income tax is dependent on the investments as well as wage increase, there is uncertainty in measuring the final tax effects (Note 29).
 
 
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 37).
 
 
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
Contract assets, contract liabilities and contract cost assets recognized under the application of IFRS 15 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 extend (or not terminate).
 
  
If any leasehold improvements are expected to have a significant remaining value, the Group is typically reasonably certain to extend (or not terminate).
 
  
Otherwise, the Group considers other factors including historical lease durations and the costs and business 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 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.

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.

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 of December 31, 2022, 2023 and 2024, if the foreign exchange rate had strengthened/weakened by 10% with all other variables held constant, the effects on profit before income tax and shareholders’ equity would have been as follows:

Computed with considering derivatives hedging effect applied by the Group to hedge foreign exchange risk of liabilities in foreign currencies.
The above analysis is a simple sensitivity analysis which assumes that all the variables other than foreign exchange rates are held constant. Therefore, the analysis does not reflect any correlation between foreign exchange rates and other variables, nor the management’s decision to decrease the risk.

(iii) Price risk
As of December 31, 2022, 2023 and 2024, the Group is exposed to equity securities price risk because the securities held by the Group are traded in active markets. If the market prices had increased/decreased by 10% with all other variables held constant, the effects on profit before income tax and equity would have been as follows:
 
(in millions of Korean won)

price
 
Impact on profit

2024.12.31
  10% 
519  
129,404 
  -10%  (519  (129,404
The analysis above is based on the assumption that the equity index had increased/decreased by 10% with all other variables held constant and all the Group’s marketable equity instruments had moved according to the historical correlation with the index. Gain or loss on equity securities classified as financial assets at fair value through profit or loss and financial assets at fair value through other comprehensive income can increase or decrease equity.
(iv) Cash flow and fair value interest rate risk
The Group’s interest rate risk arises from liabilities in foreign currency such as foreign currency debentures. Debentures in foreign currency issued at variable rates expose the Group to cash flow interest rate risk which is partially offset by swap transactions. Debentures and borrowings issued at fixed rates expose the Group to fair value interest rate risk. The Group sets the policy and operates to minimize the uncertainty of the changes in interest rates and financial costs.
As of December 31, 2022, 2023 and 2024, if the market interest rate had increased/decreased by 100 bp with other variables held constant, the effects on profit before income tax and shareholders’ equity would be as follows:
 
(in millions of Korean won)
  
Fluctuation of
interest rate

   + 100 bp   
(1,658 
(11,903
   - 100 bp    1,665   12,337 
The above analysis is a simple sensitivity analysis which assumes that all the variables other than market interest rates are held constant. Therefore, the analysis does not reflect any correlation between market interest rates and other variables, nor the management’s decision to decrease the risk.

2) Credit risk
Credit risk is the risk of financial loss to the Group if a customer or counterparty to a financial instrument fails to meet its contractual obligations and arises principally from the Group’s trade receivables from customers, debt securities and others.
 
 -
Risk management
Credit risk is managed on the Group basis with the purpose of minimizing financial loss. Credit risk arises from the normal transactions and investing activities, where clients or other party fails to discharge an obligation on contract conditions. To manage credit risk, the Group considers the counterparty’s credit based on the counterparty’s financial conditions, default history and other important factors.
Credit risk arises from cash and cash equivalents, derivative financial instruments and deposits with banks and financial institutions, as well as outstanding receivables. To minimize such risk, only the financial institutions with strong credit ratings are accepted.
The Group’s investments in debt instruments are considered to be low risk investments. The credit ratings of the investments are monitored for credit deterioration.
 
 -
Security
For some trade receivables, the Group may obtain security in the form of guarantees or letters of credit, etc. which can be called upon if the counterparty is in default under the terms of the agreement.
 
 -
Impairment of financial assets
The Group has four types of financial assets that are subject to the expected credit loss model:
 
  
trade receivables for sales of goods and provision of services,
 
  
contract assets relating to provision of services,
 
  
debt investments carried at fair value through other comprehensive income, and
 
  
other financial assets carried at amortized cost.
While cash equivalents are also subject to the impairment requirement, the identified expected credit loss was immaterial.

The Group is exposed to credit risk for financial guarantee contracts. As of December 31, 2024, the Group’s maximum exposure amount is
108,881 million (December 31, 2023:
116,719 million).
(i) Trade receivables and contract assets
The Group applies the simplified approach to measuring expected credit losses which uses a lifetime expected loss allowance for all trade receivables and contract assets.
The Group measures the expected credit loss by considering the future unrecoverable 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, 2024. 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.

During the year ended December 31, 2024, derivative liabilities
held-for-trading are
classified under the ‘more than one year to less than five years’ category as they are relevant to the fair value of derivatives liabilities related to
shareholder-to-share
contracts (Note 19).
As these derivatives
held-for-trading
are managed based on net fair value, their contractual maturities are not necessarily taking into consideration to understand the timing of cash flows.

Cash outflow and inflow of gross-settled derivatives are undiscounted contractual cash flow and may differ from the amount in the consolidated statement of financial position.
(2) Management of Capital Risk
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 capital component.
The
debt-to-equity
ratios as of December 31, 2023 and 2024, are as follows:

Total equity
   18,542,575   17,967,561 
Debt-to-equity
ratio
   131  134
The Group manages capital on the basis of the gearing ratio. This ratio is calculated as net debt divided by total capital. Net debt is calculated as total borrowings less cash and cash equivalents. Total capital is calculated as ‘equity’ in the statement of financial position plus net debt.
The gearing ratios as of December 31, 2023 and 2024, are as follows:

Fair Value Hierarchy
To provide an indication about the reliability of the inputs used in determining fair value, the Group classifies its financial instruments into the three levels prescribed under the accounting standards. Financial instruments that are measured at fair value are categorized by the fair value hierarchy, and the defined levels are as follows:
 
  
Level 1: The fair value of financial instruments traded in active markets is based on quoted market prices at the end of the reporting period. The quoted market price used for financial assets held by the Group is the current bid price. These instruments are included in level 1.
 
  
Level 2: The fair value of financial instruments that are not traded in active markets is determined using valuation techniques which maximize the use of observable market data and rely as little as possible on entity-specific estimates. If all significant inputs required to fair value an instrument are observable, the instrument is included in level 2.
 
  
Level 3: If one or more of the significant inputs is not based on observable market data, the instrument is included in level 3.
Fair value hierarchy classifications of the financial assets and financial liabilities that are measured at fair value disclosed in fair value as of December 31, 2023 and 2024, are as follows:
