Independent Auditors’ Report

Based on a report originally issued in Korean

To the Board of Directors and Shareholders of

SK Telecom Co., Ltd.:

Opinion

We have audited the accompanying consolidated financial statements of SK Telecom Co., Ltd. and its subsidiaries (the “Group”) which comprise the consolidated statements of financial position as of December 31, 2020 and 2019 and the consolidated statements of income, comprehensive income, changes in equity and cash flows for the years then ended, and notes to the consolidated financial statements, comprising significant accounting policies and other explanatory information.

In our opinion, the accompanying consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Group as of December 31, 2020 and 2019, and its consolidated financial performance and its consolidated cash flows for the years then ended in accordance with Korean International Financial Reporting Standards (“K-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 Auditors’ 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 that are relevant to our audit of the consolidated financial statements in the Republic of Korea, and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Emphasis of Matter

Without qualifying our opinion, we draw attention to the following:

As described in Note 3 to the consolidated financial statements, the Group retrospectively applied changes in accounting policies regarding the method of determining lease term and restated the comparative financial statements as of and for the year ended December 31, 2019.

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 as of and for the year ended December 31, 2020. 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.

1. Revenue Recognition

As described in note 4 (21) and 5 (2) of the consolidated financial statements, the Group’s revenue from cellular services is primarily generated from the provision of a variety of telecommunications services at various rate plans and products. Revenue from wireless service amounted to W9,801,194 million in 2020. It is recognized based on data from complex information technology systems that process large volume of transactions with subscribers. Therefore, we have identified revenue recognition related to the Group’s wireless service as a key audit matter due to the complexity of information technology systems involved and the revenue recognition standard applied.

1

The primary procedures we performed to address this key audit matter included:

• Testing certain internal controls relating to the Group’s revenue recognition process, including information technology (IT) systems used for the purposes of revenue recognition. Specifically, we assessed the IT system environment for data records, rating and billing systems, which aggregate data used for revenue recognition for voice usage, text and mobile data services, generate customer bills and support measurement of revenue.

• Comparing a sample of revenue transactions to supporting evidence, such as customer bills, rating system information, subscriber contracts, and cash received, where applicable.

• Inspecting major contracts with subscribers to assess the Group’s revenue recognition policies based on the terms and conditions as set out in the contracts, with reference to the requirements of K-IFRS No. 1115.

2. Evaluation of impairment analysis for goodwill in the security services cash generating unit

As described in notes 4 (11) and 16 of the consolidated financial statements, the Group performs impairment test for goodwill at least annually or when there is an indication of possible impairment by comparing the recoverable amount and the carrying amount of a cash generating unit (“CGU”) to which goodwill is allocated. The Group’s security services-related operating segments included security services and information security services. The amount of goodwill that is allocated to the security services CGU is W1,176,274 million as of December 31, 2020. No goodwill is allocated to the information security services CGU.

In carrying out the impairment assessment of goodwill, management determined the recoverable amount based on the value in use (“VIU”). Determining the VIU of the security services CGU involves significant judgments in estimating the expected future cash flows including the estimates of revenue growth rate, labor costs, perpetual growth rate and discount rate. In the Group’s impairment test as of December 31, 2019, the VIU of security services CGU approximated its carrying value. In its impairment test as of December 31, 2020, while the Group does not expect the total carrying amount of the CGU will exceed the VIU due to reasonably possible changes in certain assumptions, there is still a high degree of uncertainty on the other significant assumptions applied, which may impact the goodwill impairment result. As such we have identified the evaluation of goodwill impairment in the security services CGU as a key audit matter.

The primary procedures we performed to address this key audit matter included:

• Involving our internal valuation professionals to assist us in evaluating estimated revenue growth rate, labor costs and perpetual growth rate by comparison with industry reports as well as historical performance and evaluating the discount rate by comparing with the discount rate that was independently developed using publicly available market data for comparable entities.

• Performing sensitivity analysis for both the discount rate and the perpetual growth rate applied to the discounted cash flow forecasts to assess the impact of changes in these key assumptions on the conclusion reached in management’s impairment assessment.

• Evaluating estimated revenue growth rate and labor costs by comparison with the financial budgets approved by the Group and comparing the cash flow forecasts prepared in prior year with the actual results to assess the Group’s ability to accurately forecast.

3. Evaluation of fair value for intangible assets – Customer relationships

As described in note 12 of the consolidated financial statements, as a result of the merger between SK Broadband Co., Ltd., a subsidiary of SK Telecom Co., Ltd., and Tbroad Co., Ltd., the Group recognized the acquired customer relationships arising from the business combination as an identifiable intangible asset. The fair value of customer relationships amounts to W374,019 million as of April 30, 2020, the acquisition date.

2

The Group estimated the fair value of customer relationships using the multi-period excess earnings method (“MPEEM”). In applying MPEEM, the Group estimates revenue and cash flows derived from the acquired customer relationships based on estimated revenue per subscriber, estimated customer attrition rate and discount rate. Considering the significant degree of the judgment in measuring the fair value of customer relationships, we identified the evaluation of fair value for customer relationships as a key audit matter.

The primary procedures we performed to address this key audit matter included:

• Involving our internal valuation professionals to assist us in:

• Assessing the MPEEM model used for the fair value estimate considering the nature of the intangible assets and requirement by K-IFRS

• Assessing the revenue per subscriber and customer attrition rate used in the cashflow estimate by comparing with the aquiree’s historical performance; and

• Evaluating the discount rate by comparing with the discount rate that was independently developed using publicly available market data.

• For historical performance used in evaluating the reasonableness of the above assumptions, evaluating the accuracy by agreeing or recalculating using public or audited information, as applicable.

Other Matter

The procedures and practices utilized 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 these consolidated financial statements in accordance with K-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, or has no realistic alternative but to do so.

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

3

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

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

• Evaluate the appropriateness of accounting policies used in the preparation of the consolidated financial statements and the reasonableness of accounting estimates and related disclosures made by management.

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

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

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

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

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

4

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 auditors’ 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.

Notes to the Consolidated Financial Statements

For the years ended December 31, 2020 and 2019

2. Basis of Preparation

These consolidated financial statements were prepared in accordance with Korean International Financial Reporting Standards (“K-IFRS”), as prescribed in the Act on External Audits of Stock Companies, Etc in the Republic of Korea.

The accompanying consolidated financial statements comprise the Group and the Group’s investments in associates and joint ventures.

The consolidated financial statements were authorized for issuance by the Board of Directors on February 2, 2021, which will be submitted for approval at the shareholders’ meeting to be held on March 25, 2021.

(1) Basis of measurement

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

• derivative financial instruments measured at fair value;

• financial instruments measured at fair value through profit or loss (“FVTPL”);

• financial instruments measured at fair value through other comprehensive income (“FVOCI”);

• liabilities (assets) for defined benefit plans recognized at the total present value of defined benefit obligations less the net of the fair value of plan assets

(2) Functional and presentation currency

Financial statements of Group entities within the Group are prepared in functional currency of each group entity, which is the currency of the primary economic environment in which each entity operates. Consolidated financial statements of the Group are presented in Korean won, which is the Parent Company’s functional and presentation currency.

(3) Use of estimates and judgments

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

Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period prospectively.

1) Critical judgments

Information about critical judgments in applying accounting policies that have the most significant effects on the amounts recognized in the consolidated financial statements is included in notes for the following areas: consolidation (whether the Group has de facto control over an investee), and determination of stand-alone selling prices.

(3) Use- of estimates and judgments, Continued

2) Assumptions and estimation uncertainties

Information about assumptions and estimation uncertainties that have a significant risk of resulting in a material adjustment within the next financial year are included in the following notes: loss allowance (notes 7 and 37), estimated useful lives of costs to obtain a contract (notes 8), property and equipment and intangible assets (notes 4 (7), (9), 14 and 17), impairment of goodwill (notes 4 (11) and 16), recognition of provision (notes 4 (16) and 20), measurement of defined benefit liabilities (notes 4 (15) and 21), and recognition of deferred tax assets (liabilities) (notes 4 (23) and 33).

3) Fair value measurement

A number of the Group’s accounting policies and disclosures require the measurement of fair values, for both financial and non-financial assets and liabilities. The Group has an established policies and processes with respect to the measurement of fair values including Level 3 fair values, and the measurement of fair values is reviewed and is directly reported to the finance executives.

The Group regularly reviews significant unobservable inputs and valuation adjustments. If third party information, such as broker quotes or pricing services, is used to measure fair values, then the Group assesses the evidence obtained from the third parties to support the conclusion that such valuations meet the requirements of K-IFRS, including the level in the fair value hierarchy in which such valuations should be classified.

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

• Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities;

• Level 2: inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices); and

• Level 3: inputs for the asset or liability that are not based on observable market data (unobservable inputs).

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

Information about assumptions used for fair value measurements are included in note 22 and note 37.

3. Changes in Accounting Policies

The Group has initially adopted the amendments to the ’Definition of a Business’(Amendments to K-IFRS No. 1103, Business Combination) and ‘Interest Rate Benchmark Reform’(Amendments to K-IFRS No. 1109, Financial Instruments, K-IFRS No. 1039, Financial Instrument – Recognition and Measurement, K-IFRS No. 1107, Financial Instruments – Disclosures) from January 1, 2020. A number of other amended standards are effective from January 1, 2020, but they do not have a material effect on the Group’s consolidated financial statements.

The Group applied Definition of a Business (Amendments to K-IFRS No. 1103) to business combinations whose acquisition dates are on or after January 1, 2020 in assessing whether it had acquired a business or a group of assets. Details of the accounting policies are summarized in Note 4 (2).

The Group applied the interest rate benchmark reform amendments retrospectively to hedging relationships that existed at January 1, 2020 or were designated thereafter and that are directly affected by interest rate benchmark reform. The amendment also applied to the gain or loss accumulated in the cash flow hedging reserve that existed at January 1, 2020. The details of the accounting policies are disclosed in Note 4 (6). See also Note 37 for related disclosures about risks and hedge accounting.

During the annual period ended December 31, 2020, the Group changed its accounting policy by applying agenda decision, Lease Term and Useful Life of Leasehold Improvements (IFRS 16 Leases and IAS 16 Property, Plant and Equipment)—November 2019, published by International Financial Reporting Interpretations Committee (“IFRIC”) on December 16, 2019.

Prior to the change in accounting policy, the Group determined the lease term based on the assumption that the right to extent or terminate the lease is no longer enforceable if a lease contract requires the counterparty’s consent to be extended. The Group now determines the lease term as the non-cancellable period of a lease, together with both: periods covered by an option to extend the lease if the lessee is reasonably certain to exercise that option; and periods covered by an option to terminate the lease if the lessee is reasonably certain not to exercise that option. In the assessing the periods covered by an option to extend the lease if the lessee is reasonably certain to exercise that option, the Company considered if it would incur a penalty on termination that is more than insignificant.

The Group has retrospectively applied the changes in its accounting policies in connection with the IFRIC agenda decision in accordance with K-IFRS No. 1008 Accounting Policies, Changes in Accounting Estimates and Errors and restated its comparative consolidated financial statements.

4. Significant Accounting Policies

The significant accounting policies applied by the Group in the preparation of its consolidated financial statements in accordance with K-IFRS are included below. The significant accounting policies applied by the Group in these consolidated financial statements are the same as those applied by the Group in its consolidated financial statements as of and for the year ended December 31, 2019, except for the changes in accounting policies described in note 3.

(1) Operating segments

An operating segment is a component of the Group that engages in business activities from which it may earn revenues and incur expenses, including revenues and expenses that relate to transactions with any of the Group’s other components. The Group’s operating segments have been determined to be each business unit, for which the Group generates separately identifiable financial information that is regularly reported to the chief operating decision maker for the purpose of resource allocation and assessment of segment performance. The Group has five reportable segments as described in note 5. Segment results that are reported to the chief operating decision maker include items directly attributable to a segment as well as those that can be allocated on a reasonable basis.

(2) Basis of consolidation

1) Business combination

A business combination is accounted for by applying the acquisition method, unless it is a combination involving entities or businesses under common control.

Consideration transferred is generally measured at fair value, as are the identifiable net assets acquired. The amount of consideration in excess of the fair value of identifiable net assets acquired is recognized as goodwill. Any goodwill that arises is tested annually for impairment. Any gain on a bargain purchase is recognized in profit or loss immediately. Acquisition-related costs are expensed in the periods in which the costs are incurred and the services are received, except if related to the costs to issue debt or equity securities recognized based on K-IFRS No. 1032 and 1109.

Consideration transferred does not include the amount settled in relation to the pre-existing relationship. Such amounts are generally recognized through profit or loss.

Contingent consideration is measured at fair value at the acquisition date. Contingent consideration classified as equity is not remeasured and its subsequent settlement is accounted for within equity. If contingent consideration is not classified as equity, the Group subsequently recognizes changes in fair value of contingent consideration through profit or loss.

2) Non-controlling interests

Non-controlling interests are measured at their proportionate share of the acquiree’s identifiable net assets at the date of acquisition.

Changes in a Controlling Company’s ownership interest in a subsidiary that do not result in the Controlling Company losing control of the subsidiary are accounted for as equity transactions.

3) Subsidiaries

Subsidiaries are entities controlled by the Group. The Group controls an investee when it is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Consolidation of an investee begins from the date the Group obtains control of the investee and cease when the Group loses control of the investee.

4) Loss of control

If the Group loses control of a subsidiary, the Group derecognizes the assets and liabilities of the former subsidiary from the consolidated statement of financial position and recognizes gain or loss associated with the loss of control attributable to the former controlling interest. Any investment retained in the former subsidiary is recognized at its fair value when control is lost.

(2) Basis of consolidation, Continued

5) Interest in investees accounted for using the equity method

Interest in investees accounted for using the equity method composed of interest in associates and joint ventures. An associate is an entity in which the Group has significant influence, but not control, over the entity’s financial and operating policies. A joint venture is a joint arrangement whereby the Group that has joint control of the arrangement has rights to the net assets of the arrangement.

The investment in an associate and a joint venture is initially recognized at cost including transaction costs and the carrying amount is increased or decreased to recognize the Group’s share of the profit or loss and changes in equity of the associate or the joint venture after the date of acquisition.

6) Intra-group transactions

Intra-group balances and transactions, and any unrealized income and expenses arising from intra-group transactions, are eliminated in preparing the consolidated financial statements. The Group’s share of unrealized gain incurred from transactions with investees accounted for using the equity method are eliminated and unrealized loss are eliminated using the same basis if there are no evidence of asset impairments.

7) Business combinations under common control

SK Holdings Co., Ltd. is the ultimate controlling entity of the Group. The assets and liabilities acquired under business combination under common control are recognized at the carrying amounts in the ultimate controlling shareholder’s consolidated financial statements. The difference between consideration and carrying amount of net assets acquired is added to or subtracted from capital surplus and others.

(3) Cash and cash equivalents

Cash and cash equivalents comprise cash balances, call deposits and investment securities with maturities of three months or less from the acquisition date that are easily convertible to cash and subject to an insignificant risk of changes in their fair value.

(4) Inventories

Inventories are initially recognized at the acquisition cost and subsequently measured using the weighted average method. During the period, a perpetual inventory system is used to track inventory quantities, which is adjusted based on the physical inventory counts performed at the period end. When the net realizable value of inventories is less than cost, the carrying amount is reduced to the net realizable value, and any difference is charged to current period as operating expenses.

(5) Non-derivative financial assets

1) Recognition and initial measurement

Accounts receivable – trade and debt investments issued are initially recognized when they are originated. All other financial assets and financial liabilities are initially recognized when the Group becomes a party to the contractual provisions of the instrument.

A financial asset (unless an accounts receivable – trade without a significant financing component) or financial liability is initially measured at fair value plus, for an item not at FVTPL, transaction costs that are directly attributable to its acquisition or issue. An accounts receivable – trade without a significant financing component is initially measured at the transaction price.

2) Classification and subsequent measurement

On initial recognition, a financial asset is classified as measured at:

• FVTPL

• FVOCI – equity investment

• FVOCI – debt investment

• Financial assets at amortized cost

A financial asset is classified based on the business model in which a financial asset is managed and its contractual cash flow characteristics.

Financial assets are not reclassified subsequent to their initial recognition unless the Group changes its business model for managing financial assets, in which case all affected financial assets are reclassified on the first day of the first reporting period following the change in the business model.

A financial asset is measured at amortized cost if it meets both of the following conditions and is not designated as at FVTPL:

• it is held within a business model whose objective is to hold assets to collect contractual cash flows; and

• its contractual terms give rise to cash flows that are solely payments of principal and interest on the principal amount outstanding on specified dates.

2) Classification and subsequent measurement, Continued

A debt investment is measured at FVOCI if it meets both of the following conditions and is not designated as at FVTPL:

• it is held within a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets; and

• its contractual terms give rise to cash flows that are solely payments of principal and interest on the principal amount outstanding on specified dates.

On initial recognition of an equity investment that is not held for trading, the Group may irrevocably elect to present subsequent changes in the investment’s fair value in other comprehensive income (“OCI”). This election is made on an investment-by-investment basis.

All financial assets not classified as measured at amortized cost or FVOCI as described above are measured at FVTPL. This includes all derivative financial assets. On initial recognition, the Group may irrevocably designate a financial asset that otherwise meets the requirements to be measured at amortized cost or at FVOCI as at FVTPL if doing so eliminates or significantly reduces an accounting mismatch that would otherwise arise.

The following accounting policies are applied to the subsequent measurement of financial assets.

Financial assets at FVTPL	These assets are subsequently measured at fair value. Net gains and losses, including any interest or dividend income, are recognized in profit or loss.
Financial assets at amortized cost	These assets are subsequently measured at amortized cost using the effective interest method. The amortized cost is reduced by impairment losses. Interest income, foreign exchange gains and losses and impairment are recognized in profit or loss. Any gain or loss on derecognition is recognized in profit or loss.
Debt investments at FVOCI	These assets are subsequently measured at fair value. Interest income calculated using the effective interest method, foreign exchange gains and losses and impairment are recognized in profit or loss. Other net gains and losses are recognized in OCI. On derecognition, gains and losses accumulated in OCI are reclassified to profit or loss.
Equity investments at FVOCI	These assets are subsequently measured at fair value. Dividends are recognized as income in profit or loss unless the dividend clearly represents a recovery of the cost of the investment. Other net gains and losses are recognized in OCI and are never reclassified to profit or loss.

3) Impairment

The Group estimates the expected credit losses (ECL) for the debt instruments measured at amortized cost and FVOCI based on the Group’s historical experience and informed credit assessment that includes forward-looking information. The impairment approach is decided based on the assessment of whether the credit risk of a financial asset has increased significantly since initial recognition. However, the Group applies a practical expedient and recognizes impairment losses equal to lifetime ECLs for accounts receivable – trade and lease receivables from the initial recognition.

ECL is a probability-weighted estimate of credit losses. Credit losses are measured as the present value of all cash shortfalls (i.e. the difference between the cash flows due to the entity in accordance with the contract and the cash flows that the Group expects to receive).

At each reporting date, the Group assesses whether financial assets measured at amortized cost and debt investments at FVOCI are credit-impaired. A financial asset is ‘credit-impaired’ when one or more events that have a detrimental impact on the estimated future cash flows of the financial asset have occurred.

Loss allowance on financial assets measured at amortized cost is deducted from the carrying amount of the respective assets, while loss allowance on debt instruments at FVOCI is recognized in OCI, instead of reducing the carrying amount of the transferred assets.

4) Derecognition

Financial assets are derecognized if the Group’s contractual rights to the cash flows from the financial assets expire or if the Group transfers the financial asset to another party without retaining control or transfers substantially all of the risks and rewards of asset.

The transferred assets are not derecognized when the Group enters into transactions whereby it transfers assets recognized in its statement of financial position but retains substantially all of the risks and rewards of the transferred assets.

5) Offsetting

Financial assets and financial liabilities are offset and the net amount is presented in the statement of financial position when the Group currently has a legally enforceable right to offset the recognized amounts and intends either to settle on a net basis or to settle the liability and realize the asset simultaneously.

A financial asset and a financial liability are offset only when the right to set off the amount is not contingent on future event and legally enforceable even on the event of default, insolvency or bankruptcy.

(6) Derivative financial instruments and hedge accounting

Derivatives are initially recognized at fair value. Subsequent to initial recognition, derivatives are measured at fair value at the end of each reporting period, and changes therein are accounted for as described below.

1) Hedge accounting

The Group holds forward exchange contracts, interest rate swaps, currency swaps and other derivative contracts to manage interest rate risk and foreign exchange risk. The Group designates derivatives as hedging instruments to hedge the variability in cash flow associated with highly probable forecasted transactions or firm commitments (a cash flow hedge).

On initial designation of the hedge, the Group formally documents the relationship between the hedging instrument(s) and hedged item(s), including the risk management objectives and strategy in undertaking the hedge transaction, together with the methods that will be used to assess the effectiveness of the hedging relationship.

Hedges directly affected by interest rate benchmark reform

For the purpose of evaluating whether there is an economic relationship between the hedged items and the hedging instruments, the Group assumes that the interest rate benchmark on which the hedged items and the hedging instruments are based is not altered as a result of interest rate benchmark reform.

For a cash flow hedge of a forecast transaction, the Group assumes that the benchmark interest rate will not be altered as a result of interest rate benchmark reform for the purpose of assessing whether the forecast transaction is highly probable and presents an exposure to variations in cash flows that could ultimately affect profit and loss. In determining whether a previously designated forecast transaction in a discontinued cash flow hedge is still expected to occur, the Group assumes that the interest rate benchmark cash flows designated as a hedge will not be altered as a result of interest rate benchmark reform.

The Group will cease applying the specific policy for assessing the economic relationship between the hedged item and the hedging instrument (i) to a hedged item or hedging instrument when the uncertainty arising from interest rate benchmark reform is no longer present with respect to the timing and the amount of the interest rate benchmark-based cash flows of the respective item or instrument or (ii) when the hedging relationship is discontinued.

For its highly probable assessment of the hedged item, the Group will no longer apply the specific policy when the uncertainty arising from interest rate benchmark reform about the timing and the amount of the interest rate benchmark-based future cash flows of the hedged item is no longer present, or when the hedging relationship is discontinued.

(6) Derivative financial instruments and hedge accounting, Continued

1) Hedge accounting, Continued

Cash flow hedge

When a derivative is designated to hedge the variability in cash flows attributable to a particular risk associated with a recognized asset or liability or a highly probable forecasted transaction that could affect profit or loss, the effective portion of changes in the fair value of the derivative is recognized in other comprehensive income, net of tax, and presented in the hedging reserve in equity. Any ineffective portion of changes in the fair value of the derivative is recognized immediately in profit or loss. If the hedging instrument no longer meets the criteria for hedge accounting, expires or is sold, terminated, exercised, or the designation is revoked, then hedge accounting is discontinued prospectively. The cumulative gain or loss on the hedging instrument that has been recognized in other comprehensive income is reclassified to profit or loss in the periods during which the forecasted transaction occurs. If the forecasted transaction is no longer expected to occur, then the balance in other comprehensive income is recognized immediately in profit or loss.

2) Other derivative financial instruments

Other derivative financial instrument not designated as a hedging instrument are measured at fair value, and the changes in fair value of the derivative financial instrument is recognized immediately in profit or loss.

(7) Property and equipment

Property and equipment are initially measured at cost. The cost of property and equipment includes expenditures arising directly from the construction or acquisition of the asset, any costs directly attributable to bringing the asset to the location and condition necessary for it to be capable of operating in the manner intended by management and the initial estimate of the costs of dismantling and removing the item and restoring the site on which it is located.

Property and equipment, subsequently, are carried at cost less accumulated depreciation and accumulated impairment losses.

Subsequent costs are recognized in the carrying amount of property and equipment at cost or, if appropriate, as a separate item if it is probable that future economic benefits associated with the item will flow to the Group and the cost of the item can be reliably measured. The carrying amount of the replaced part is derecognized. The costs of the day-to-day servicing are recognized in profit or loss as incurred.

Property and equipment, except for land, are depreciated on a straight-line basis over estimated useful lives that appropriately reflect the pattern in which the asset’s future economic benefits are expected to be consumed. A component that is significant compared to the total cost of property and equipment is depreciated over its separate useful life.

Gains and losses on disposal of an item of property and equipment are determined by comparing the proceeds from disposal with the carrying amount of property and equipment and are recognized as other non-operating income (loss).

(7) Property and equipment, Continued

The estimated useful lives of the Group’s property and equipment are as follows:

	Useful lives (years)
Buildings and structures	15 ~ 40
Machinery	3 ~ 15, 30
Other property and equipment	2 ~10

Depreciation methods, useful lives, and residual values are reviewed at the end of each reporting date and adjusted, if appropriate. The change is accounted for as a change in an accounting estimate.

(8) Borrowing costs

The Group capitalizes borrowing costs directly attributable to the acquisition, construction or production of a qualifying asset as part of the cost of that asset. Other borrowing costs are recognized in expense as incurred. A qualifying asset is an asset that requires a substantial period of time to get ready for its intended use or sale. Financial assets are not qualifying assets, and assets that are ready for their intended use or sale when acquired are not qualifying assets either.

To the extent that the Group borrows funds specifically for the purpose of obtaining a qualifying asset, the Group determines the amount of borrowing costs eligible for capitalization as the actual borrowing costs incurred on that borrowing during the period less any investment income on the temporary investment of those borrowings. To the extent that the Group borrows funds generally and uses them for the purpose of obtaining a qualifying asset, the Group determines the amount of borrowing costs eligible for capitalization by applying a capitalization rate to the expenditures on that asset. The capitalization rate is the weighted average of the borrowing costs applicable to the borrowings of the Group that are outstanding during the period other than borrowings made specifically for the purpose of obtaining a qualifying asset. The amount of borrowing costs that the Group capitalizes during a period do not exceed the amount of borrowing costs incurred during the period.

(9) Intangible assets

Intangible assets are measured initially at cost and, subsequently, are carried at cost less accumulated amortization and accumulated impairment losses.

Intangible assets, except for goodwill, are amortized on a straight-line basis over the estimated useful lives of intangible assets from the date that they are available for use. The residual value of intangible assets is zero. However, club memberships and brand are expected to be available for use as there are no foreseeable limits to the periods. These intangible assets are determined as having indefinite useful lives and, therefore, not amortized.

(9) Intangible assets, Continued

The estimated useful lives of the Group’s intangible assets are as follows:

	Useful lives (years)
Frequency usage rights	5 ~ 10
Land usage rights	5
Industrial rights	5, 10
Development costs	3 ~ 5
Facility usage rights	10, 20
Customer relations	3 ~ 20
Other	3 ~ 20

Amortization periods and the amortization methods for intangible assets with finite useful lives are reviewed at the end of each reporting period. The useful lives of intangible assets that are not being amortized are reviewed at the end of each reporting period to determine whether events and circumstances continue to support indefinite useful life assessments for those assets. Changes, if appropriate, are accounted for as changes in accounting estimates.

Expenditures on research activities are recognized in profit or loss as incurred. Development expenditures are capitalized only if development costs can be reliably measured, the product or process is technically and commercially feasible, future economic benefits are probable, and the Group intends to and has sufficient resources to complete development and to use or sell the asset. Other development expenditures are recognized in profit or loss as incurred.

Subsequent expenditures are capitalized only when they increase the future economic benefits embodied in the specific asset to which it relates. All other expenditures, including expenditures on internally generated goodwill and brands, are recognized in profit or loss as incurred.

(10) Government grants

Government grants are not recognized unless there is reasonable assurance that the Group will comply with the grant’s conditions and that the grant will be received.

1) Grants related to assets

Government grants whose primary condition is that the Group purchases, constructs, or otherwise acquires a long-term asset are deducted in calculating the carrying amount of the asset. The grant is recognized in profit or loss over the life of a depreciable asset as a reduction to depreciation expense.

2) Grants related to income

Government grants which are intended to compensate the Group for expenses incurred are deducted from the related expenses.

(11) Impairment of non-financial assets

The carrying amounts of the Group’s non-financial assets other than contract assets recognized for revenue arising from contracts with a customer, assets recognized for the costs to obtain or fulfill a contract with a customer, employee benefits, inventories, deferred tax assets, and non-current assets held for sale are reviewed at the end of the reporting period to determine whether there is any indication of impairment. If any such indication exists, then the asset’s recoverable amount is estimated. Goodwill and intangible assets that have indefinite useful lives or that are not yet available for use, irrespective of whether there is any indication of impairment, are tested for impairment annually by comparing their recoverable amounts to their carrying amounts.

The Group estimates the recoverable amount of an individual asset, and if it is impossible to measure the individual recoverable amount of an asset, the Group estimates the recoverable amount of cash-generating unit (“CGU”). A CGU is the smallest identifiable group of assets that generates cash inflows that are largely independent of the cash inflows from other assets or groups of assets. The recoverable amount of an asset or CGU is the greater of its value in use and its fair value less costs to sell. The value in use is estimated by applying a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset or CGU for which estimated future cash flows have not been adjusted, to the estimated future cash flows expected to be generated by the asset or CGU.

An impairment loss is recognized in profit or loss to the extent the carrying amount of the asset exceeds its recoverable amount.

Goodwill acquired in a business combination is allocated to each CGU that is expected to benefit from the synergy arising from the business acquired. Any impairment identified at the CGU level will first reduce the carrying amount of goodwill and then be used to reduce the carrying amount of the other assets in the CGU on a pro rata basis. Except for impairment losses in respect of goodwill which are never reversed, an impairment loss is reversed if there has been a change in the estimates used to determine the recoverable amount. An impairment loss is reversed only to the extent that the asset’s carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortization, if no impairment loss had been recognized.

(12) Leases

A contract is or contains, a lease if the contract transfers a right to control the identified asset for a period of time in exchange for consideration.

1) As a lessee

At commencement or on modification of a contract that contains a lease component, the Group allocates the consideration in the contract to each lease component on the basis of its relative stand-alone prices. However, the Group has elected not to separate non-lease components and account for the lease and non-lease components as a single lease component.

The Group recognizes a right-of-use asset and a lease liability at the lease commencement date. The right-of-use asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for any lease payments made at of before the commencement date, plus any initial direct costs incurred and an estimate of costs to dismantle and remove the underlying asset or to restore the underlying asset or the site on which it is located, less any lease incentives received.

The right-of-use asset is subsequently depreciated using the straight-line method from the commencement date to the end of the lease term, unless the lease transfers ownership of the underlying asset to the Group by the end of the lease term or the cost of the right-of-use asset reflects that the Group will exercise a purchase option. In that case the right-of-use asset will be depreciated over the useful life of the underlying asset, which is determined on the same basis as those of property and equipment. In addition, the right-of-use asset is periodically reduced by impairment losses, if any, and adjusted for certain remeasurements of the lease liability.

The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the Group’s incremental borrowing rate. Generally, the Group uses its incremental borrowing rate as the discount rate.

The Group determines its incremental borrowing rate by obtaining interest rates from various external financing sources and makes certain adjustments to reflect the terms of the lease and type of the asset leased.

Lease payments included in the measurement of the lease liability comprise the following:

• fixed payments, including in-substance fixed payments;

• variable lease payments that depend on an index or a rate, initially measured using the index or rate as at the commencement date;

• amounts expected to be payable under a residual value guarantee; and

• the exercise price under a purchase option that the Group is reasonably certain to exercise, lease payments in an optional renewal period if the Group is reasonably certain to exercise an extension option, and penalties for early termination of a lease unless the Group is reasonably certain not to terminate early.

The lease liability is measured at amortized cost using the effective interest method. It is remeasured when there is a change in future lease payments arising from a change in an index or rate, if there is a change in the Group’s estimate of the amount expected to be payable under a residual value guarantee, if the Group changes its assessment of whether it will exercise a purchase, extension of termination option of if there is a revised in-substance fixed lease payment.

(12) Leases, Continued

1) As a lessee, Continued

When the lease liability is remeasured in this way, a corresponding adjustment is made to the carrying amount of the right-of-use asset, or is recorded in profit or loss if the carrying amount of the right-of-use asset has been reduced to zero.

The Group presents right-of-use assets that do not meet the definition of investment property in ‘property and equipment’ in the statement of financial position.

The Group has elected not to recognize right-of-use assets and lease liabilities for leases of low-value assets and short-term leases. The Group recognizes the lease payments associated with lease as an expense on a straight-line basis over the lease term.

2) As a lessor

At inception or on modification of a contract that contains a lease component, the Group allocates the consideration in the contract to each lease component on the basis of their relative stand-alone prices.

When the Group acts as a lessor, it determines at lease inception whether each lease is a finance lease or an operation lease.

To classify each lease, the Group makes an overall assessment of whether the lease transfers substantially all of the risks and rewards incidental to ownership of the underlying asset. If this is the case, then the lease is a finance lease; if not, then it is an operating lease. As part of this assessment, the Group considers certain indicators such as whether the lease is for the major part of the economic life of the asset.

When the Group is an intermediate lessor, is accounts for its interests in the head lease and the sub-lease separately. It assesses the lease classification of a sub-lease with reference to the right-of-use asset arising from the head lease, not with reference to the underlying asset. If a head lease is a short-term lease to which the Group applies the exemption described above, then it classifies the sub-lease as an operating lease.

If an arrangement contains lease and non-lease components, then the Group applies K-IFRS No. 1115 to allocate the consideration in the contract.

The Group applies derecognition and impairment requirements in K-IFRS No. 1109 to the net investment in the lease. The Group further regularly reviews estimated unguaranteed residual values used in calculating the gross investment in the lease.

The Group recognizes lease payments received under operating leases as income on a straight-line basis over the lease term as part of ‘other revenue’.

(13) Non-current assets held for sale

Non-current assets, or disposal groups comprising assets and liabilities, that are expected to be recovered primarily through sales rather than through continuing use, are classified as held for sale. In order to be classified as held for sale, the assets (or disposal groups) must be available for immediate sale in their present condition and their sale must be highly probable. The assets or disposal groups that are classified as non-current assets held for sale are measured at the lower of their carrying amounts and fair value less cost to sell. The Group recognizes an impairment loss for any initial or subsequent write-down of assets (or disposal groups) to fair value less costs to sell and a gain for any subsequent increase in fair value less costs to sell up to the cumulative impairment loss previously recognized in accordance with K-IFRS No. 1036, Impairment of Assets.

A non-current asset that is classified as held for sale or part of a disposal group classified as held for sale is not depreciated (or amortized).

(14) Non-derivative financial liabilities

The Group classifies non-derivative financial liabilities into financial liabilities at fair value through profit or loss or other financial liabilities in accordance with the substance of the contractual arrangement. The Group recognizes financial liabilities in the consolidated statement of financial position when the Group becomes a party to the contractual provisions of the financial liabilities.

1) Financial liabilities at fair value through profit or loss

Financial liabilities at fair value through profit or loss include financial liabilities held for trading or designated as such upon initial recognition. Subsequent to initial recognition, these liabilities are measured at fair value. The amount of change in fair value of financial liability that is attributable to changes in the credit risk of that liability shall be presented in other comprehensive income, and the remaining amount of change in the fair value of the liability shall be presented in profit or loss. Upon initial recognition, transaction costs that are directly attributable to the issue of the financial liability are recognized in profit or loss as incurred.

2) Other financial liabilities

Non-derivative financial liabilities other than financial liabilities at fair value through profit or loss are classified as other financial liabilities. At the date of initial recognition, other financial liabilities are measured at fair value minus transaction costs that are directly attributable to the issue of the financial liabilities. Subsequent to initial recognition, other financial liabilities are measured at amortized cost and the interest expenses are recognized using the effective interest method.

3) Derecognition of financial liability

The Group extinguishes a financial liability only when the contractual obligation is fulfilled, canceled or expires. The Group recognizes new financial liabilities at fair value based on new contracts and eliminates existing liabilities when the contractual terms of the financial liabilities change and the cash flows change substantially.

When a financial liability is derecognized, the difference between the carrying amount and the consideration paid (including any transferred non-cash assets or liabilities assumed) is recognized in profit or loss.

4 Significant Accounting Policies, Continued

(15) Employee benefits

1) Short-term employee benefits

Short-term employee benefits are employee benefits that are due to be settled within 12 months after the end of the period in which the employees render related services. When an employee has rendered a service to the Group during an accounting period, the Group recognizes the undiscounted amount of short-term employee benefits expected to be paid in exchange for that service.

2) Other long-term employee benefits

Other long-term employee benefits include employee benefits that are settled beyond 12 months after the end of the period in which the employees render related services. The Group’s net obligation in respect of long-term employee benefits is the amount of future benefit that employees have earned in return for their service in the current and prior periods. That benefit is discounted to determine its present value. Remeasurements are recognized in profit or loss in the period in which they arise.

3) Retirement benefits: defined contribution plans

When an employee has rendered a service to the Group during a period, the Group recognizes the contribution payable to a defined contribution plan in exchange for that service as a liability (accrued expense), after deducting any contribution already paid. If the contribution already paid exceeds the contribution due for service before the end of the reporting period, the Group recognizes that excess as an asset (prepaid expense) to the extent that the prepayment will lead to a reduction in future payments or a cash refund.

4) Retirement benefits: defined benefit plans

At the end of reporting period, defined benefit liabilities relating to defined benefit plans are recognized at present value of defined benefit obligations net of fair value of plan assets.

The calculation is performed annually by an independent actuary using the projected unit credit method. When the fair value of plan assets exceeds the present value of the defined benefit obligation, the Group recognizes an asset, to the extent of the present value of any economic benefits available in the form of refunds from the plan or reduction in the future contributions to the plan.

Remeasurements of the net defined benefit liability (asset), which comprise actuarial gains and losses, the return on plan assets (excluding interest) and the effect of the asset ceiling (if any, excluding interest), are recognized immediately in other comprehensive income. The Group determines net interests on net defined benefit liability (asset) by multiplying discount rate determined at the beginning of the annual reporting period and considers changes in net defined benefit liability (asset) from contributions and benefit payments. Net interest costs and other costs relating to the defined benefit plan are recognized through profit or loss.

When the plan amendment or curtailment occurs, gains or losses on amendment or curtailment in benefits for the past service provided are recognized through profit or loss. The Group recognizes a gain or loss on a settlement when the settlement of defined benefit plan occurs.

(15) Employee benefits, Continued

5) Termination benefits

The Group recognizes a liability and expense for termination benefits at the earlier of the period when the Group can no longer withdraw the offer of those benefits and the period when the Group recognizes costs for a restructuring that involves the payment of termination benefits. If benefits are payable more than 12 months after the reporting period, they are discounted to their present value.

(16) Provisions

Provisions are recognized when the Group has a present legal or constructive obligation as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation, and a reliable estimate can be made of the amount of the obligation.

The risks and uncertainties that inevitably surround many events and circumstances are taken into account in reaching the best estimate of a provision. If the effect of the time value of money is material, provisions are determined at the present value of the expected future cash flows.

If some or all of the expenditures required to settle a provision are expected to be reimbursed by another party, the reimbursement is recognized when, and only when, it is virtually certain that reimbursement will be received if the entity settles the obligation. The reimbursement is treated as a separate asset.

Provisions are reviewed at the end of each reporting period and adjusted to reflect the current best estimates. If it is no longer probable that an outflow of resources embodying economic benefits will be required to settle the obligation, the provision is reversed.

A provision is used only for expenditures for which the provision was originally recognized.

(17) Transactions in foreign currencies

1) Foreign currency transactions

Transactions in foreign currencies are translated to the functional currency of the Group at exchange rates at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are retranslated to the functional currency using the exchange rate at the reporting date. Non-monetary assets and liabilities denominated in foreign currencies that are measured at fair value are retranslated to the functional currency at the exchange rate at the date that the fair value was determined.

Foreign currency differences arising on retranslation are recognized in profit or loss, except for the differences arising on the retranslation of available-for-sale equity instruments.

(17) Transactions in foreign currencies, Continued

2) Foreign operations

If the presentation currency of the Group is different from a foreign operation’s functional currency, the financial statements of the foreign operation are translated into the presentation currency using the following methods:

The assets and liabilities of foreign operations, whose functional currency is not the currency of a hyperinflationary economy, are translated to presentation currency at exchange rates at the reporting date. The income and expenses of foreign operations are translated to functional currency at exchange rates at the dates of the transactions. Foreign currency differences are recognized in other comprehensive income.

Any goodwill arising on the acquisition of a foreign operation and any fair value adjustments to the carrying amounts of assets and liabilities arising on the acquisition of that foreign operation is treated as assets and liabilities of the foreign operation. Thus, they are expressed in the functional currency of the foreign operation and translated at the closing rate at the reporting date.

When a foreign operation is disposed, the relevant amount in the translation is transferred to profit or loss as part of the profit or loss on disposal. On the partial disposal of a subsidiary that includes a foreign operation, the relevant proportion of such cumulative amount is reattributed to non-controlling interest. In any other partial disposal of a foreign operation, the relevant proportion is reclassified to profit or loss.

(18) Share capital

Ordinary shares are classified as equity. Incremental costs directly attributable to the issuance of ordinary shares and share options are recognized as a deduction from equity, net of any tax effects.

When the Parent Company repurchases its own shares, the amount of the consideration paid is recognized as a deduction from equity and classified as treasury shares. The gains or losses from the purchase, disposal, reissue, or retirement of treasury shares are directly recognized in equity being as transaction with owners.

(19) Hybrid bond

The Group recognizes a financial instrument issued by the Group as an equity instrument if it does not include contractual obligation to deliver financial assets including cash to the counter party.

(20) Share-based Payment

For equity-settled share-based payment transaction, if the fair value of the goods or services received cannot be reliably estimated, the Group measures the value indirectly by reference to the fair value of the equity instruments granted. The related expense with a corresponding increase in capital surplus and others is recognized over the vesting period of the awards.

The amount recognized as an expense is adjusted to reflect the number of awards for which the related service and non-market performance conditions are expected to be met, such that the amount ultimately recognized is based on the number of awards that meet the related service and non-market performance conditions at the vesting date.

(20) Share-based Payment, Continued

The fair value of the amount payable to employees in respect of share appreciation rights, which are settled in cash, is recognized as an expense with a corresponding increase in liabilities, over the period during which the employees become unconditionally entitled to payment. The liability is remeasured at each reporting date and at settlement date based on the fair value of the share appreciation rights. Any changes in the liability are recognized in profit or loss.

(21) Revenue

1) Identification of performance obligations in contracts with customers

The Group identifies the distinct services or goods as performance obligations in contracts with customers such as (1) providing wireless telecommunications services, (2) sale of handsets and (3) providing other goods and services. In the case of providing both wireless telecommunications service and selling a handset together to one customer, the Group allocates considerations from the customer between the separate performance obligations for handset sale and wireless telecommunications service. The handset sale revenue is recognized when handset is delivered, and the wireless telecommunications service revenue is recognized over the period of the contract term as stated in the subscription contract.

2) Allocation of the transaction price to each performance obligation

The Group allocates the transaction price of a contract to each performance obligation identified on a relative stand-alone selling price basis. The Group uses “adjusted market assessment approach” for estimating the stand-alone selling price of a good or service. As an exception, the Group uses “expected cost plus a margin approach” for insignificant transactions.

3) Incremental costs of obtaining a contract

The Group pays commissions to its retail stores and authorized dealers in connection with acquiring service contracts. The commissions paid to these parties constituted a significant portion of the Group’s operating expenses. These commissions would not have been paid if there have been no binding contracts with subscribers and, therefore, the Group capitalizes certain costs associated with commissions paid to obtain new customer contracts and amortize them over the expected contract periods.

4) Customer loyalty programs

The Group provides customer loyalty points to customers based on the usage of the service to which the Group allocates a portion of consideration received as a performance obligation distinct from wireless telecommunications services. The amount to be allocated to the loyalty program is measured according to the relative stand-alone selling price of the customer loyalty points. The amount allocated to the loyalty program is deferred as a contract liability and is recognized as revenue when loyalty points are redeemed.

5) Consideration payable to a customer

Based on the subscription contract, a customer who uses the Group’s wireless telecommunications services may receive a discount for purchasing goods or services from a designated third party. The Group pays a portion of the price discounts that the customer receives to the third party which is viewed as consideration payable to a customer.

The Group accounts for the amounts payable to the third party as a reduction of the wireless telecommunications service revenue.

(22) Finance income and finance costs

Finance income comprises interest income on funds invested (including financial assets measured at fair value), dividend income, gains on disposal of financial assets at FVTPL, changes in fair value of financial instruments at FVTPL, and gains on hedging instruments that are recognized in profit or loss. Interest income is recognized as it accrues in profit or loss, using the effective interest rate method. Dividend income is recognized in profit or loss when the right to receive the dividend is established.

Finance costs comprise interest expense on borrowings, changes in fair value of financial instruments at FVTPL, and losses on hedging instruments that are recognized in profit or loss. Interest expense on borrowings and debentures is recognized as it accrues in profit or loss using the effective interest rate method.

(23) Income taxes

Income tax expense comprises current and deferred tax. Current tax and deferred tax are recognized in profit or loss except to the extent that it relates to a business combination, or items recognized directly in equity or in OCI.

The Group pays income tax in accordance with the tax-consolidation system when the Parent Company and its subsidiaries are economically unified.

1) Current tax

Current tax is the expected tax payable or receivable on the taxable profit or loss for the year, using tax rates enacted or substantively enacted at the end of the reporting period, and includes interests and fines related to income taxes paid or payable. The taxable profit is different from the accounting profit for the period since the taxable profit is calculated excluding the temporary differences, which will be taxable or deductible in determining taxable profit (tax loss) of future periods, and non-taxable or non-deductible items from the accounting profit.

(23) Income taxes, Continued

2) Deferred tax

Deferred tax is recognized by using the asset-liability method in respect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. The Group recognizes a deferred tax liability for all taxable temporary differences, except for the difference associated with investments in subsidiaries and associates 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. The Group recognizes a deferred tax asset for all deductible temporary differences to the extent that it is probable that the temporary difference will reverse in the foreseeable future and taxable profit will be available against which the temporary difference can be utilized.

A deferred tax asset is recognized for the carryforward of unused tax losses and unused tax credits to the extent that it is probable that future taxable profit will be available against which the unused tax losses and unused tax credits can be utilized. Future taxable profit is dependent on the reversal of taxable temporary differences. If there are insufficient taxable temporary differences to recognize the deferred tax asset, the business plan of the Group and the reversal of existing temporary differences are considered in determining the future taxable profit.

The Group reviews the carrying amount of a deferred tax asset at the end of each reporting period and reduces the carrying amount to the extent that it is no longer probable that sufficient taxable profit will be available to allow the benefit of part or all of that deferred tax asset to be utilized.

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the period when the asset is realized, or the liability is settled based on tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period. The measurement of deferred tax liabilities and deferred tax assets reflects the tax consequences that would follow from the manner in which the Group expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities.

Deferred tax assets and liabilities are offset only if the Group has a legally enforceable right to offset the amount recognized and intends to settle the current tax liabilities and assets on a net basis. Income tax expense in relation to dividend payments is recognized when liabilities relating to the dividend payments are recognized.

3) Uncertainty over income tax treatments

The Group assesses the uncertainty over income tax treatments pursuant to K-IFRS No. 1012. If the Group concludes it is not probable that the taxation authority will accept an uncertain tax treatment, the Group reflects the effect of uncertainty for each uncertain tax treatment by using either of the following methods, depending on which method the entity expects to better predict the resolution of the uncertainty:

• The most likely amount: the single most likely amount in a range of possible outcomes.

• The expected value: the sum of the probability-weighted amounts in a range of possible outcomes.

(24) Earnings per share

The Group presents basic and diluted earnings per share (EPS) data for its ordinary shares. Basic EPS is calculated by dividing the profit or loss attributable to ordinary shareholders of the Parent Company by the weighted average number of ordinary shares outstanding during the period, adjusted for own shares held. Diluted EPS is determined by adjusting the profit or loss attributable to ordinary shareholders and the weighted average number of ordinary shares outstanding, adjusted for own shares held, for the effects of all dilutive potential ordinary shares, which comprise share options granted to employees, if any.

(25) Standards issued but not yet effective

The following new standards are effective for annual periods beginning after January 1, 2020 and earlier application is permitted. However, the Group has not adopted the following new standards early in preparing the accompanying consolidated financial statements.

Interest Rate Benchmark Reform — Phase 2

(Amendments to K-IFRS No. 1109, Financial Instruments, K-IFRS No. 1039, Financial Instrument-Recognition and Measurement, K-IFRS No. 1107, Financial Instruments-Disclosures, K-IFRS No. 1104 Insurance Contracts and K-IFRS No. 1116, Leases)

The amendments address issues that might affect financial reporting as a result of the reform of an interest rate benchmark, including the effects of changes to contractual cash flows or hedging relationships arising from the replacement of an interest rate benchmark with an alternative benchmark rate. The amendments provide practical relief from certain requirements in K-IFRS No. 1109, Financial Instruments, K-IFRS No. 1039, Financial Instrument-Recognition and Measurement, K-IFRS No. 1107, Financial Instruments-Disclosures, K-IFRS No. 1104 Insurance Contracts and K-IFRS No. 1116, Lease.

The amendments will require the Group to account for a change in the basis for determining the contractual cash flows of a financial asset or financial liability that is required by interest rate benchmark reform by updating the effective interest rate of the financial asset or financial liability.

As of December 31, 2020, the Group has LIBOR floating rate notes amounting to W326,400 million that will be subject to IBOR reform. The Group has not determined an alternative interest rate benchmark to LIBOR for these notes as of December 31, 2020 and these amendments are not expected to have a significant impact on the Group’s statement of income.

The amendments provide exceptions to the hedge accounting requirements in the following areas.

• Allow amendment of the designation of a hedging relationship to reflect changes that are required by the reform.

• When a hedged item in a cash flow hedge is amended to reflect the changes that are required by the reform, the amount accumulated in the cash flow hedge reserve will be deemed to be based on the alternative benchmark rate on which the hedged future cash flows are determined.

• When a group of items is designated as a hedged item and an item in the Group is amended to reflect the changes that are required by the reform, the hedged items are allocated to sub- groups based on the benchmark rates being hedged.

• If an entity reasonably expects that an alternative benchmark rate will be separately identifiable within a period of 24 months, it is not prohibited from designating the rate as a non-contractually specified risk component if it is not separately identifiable at the designation date.

(25) Standards issued but not yet effective, Continued

As of December 31, 2020, the Group has cash flow hedges of LIBOR risk. The Group has not identified the alternative interest rate benchmark to LIBOR for indexation of the hedged items and hedging instruments. When LIBOR is replaced by the alternative interest rate, the Group expects to apply the amendments related to hedge accounting. However, there is uncertainty about when and how replacement may occur. When the change occurs to the hedged item or the hedging instrument, the Group will remeasure the cumulative change in fair value of the hedged item or the fair value of the interest rate swap, respectively, based on the alternative interest rate to LIBOR. Hedging relationships may experience hedge ineffectiveness if there is a timing or other mismatch between the transition. The Group does not expect that the amounts accumulated in the cash flow hedge reserve will be immediately reclassified to profit or loss because of IBOR transition.

The amendments will require the Group to disclose additional information about the Group’s exposure to risks arising from interest rate benchmark reform and related risk management activities.

The Group plans to apply the amendments from January 1, 2021. Application will not impact amounts reported for 2020 or prior periods.

The following new and amended standards are not expected to have a significant impact on the Group’s separate financial statements.

• COVID-19-Related Rent Concessions (Amendment to K-IFRS No. 1116).

• Property, Plant and Equipment: Proceeds before Intended Use (Amendments to K-IFRS No. 1016).

• Reference to Conceptual Framework (Amendments to K-IFRS No. 1103).

• Classification of Liabilities as Current or Non-current (Amendments to K-IFRS No. 1001).

• K-IFRS No. 1117 Insurance Contracts and amendments to K-IFRS No. 1117 Insurance Contracts.

5. Operating Segments

The Group’s operating segments have been identified to be each business unit, by which the Group provides independent services and merchandise. The Group’s reportable segments are cellular services, which include cellular voice service, wireless data service and wireless internet services; fixed-line telecommunication services, which include telephone services, internet services, and leased line services; security services, which include unmanned security services, manned security services and system software development; commerce services, the open marketplace platform; and all other businesses, which include the Group’s internet portal services and other immaterial operations, each of which does not meet the quantitative threshold to be considered as a reportable segment and are presented collectively as others.

(*) During the year ended December 31, 2019, due to the change in the categorization of information reviewed by the chief operating decision maker in 2019, the Group reclassified SK stoa Co., Ltd. from Fixed-line telecommunication Service segment to Commerce Services segment. In addition, operating segment for Life & Security Holdings Co., Ltd. and SK Infosec Co., Ltd. was separately presented as a reportable segment (Security Services) and no longer included in Others segment.

In addition, as a result of change in accounting policy in connection with the determination of lease term (note 3), the Group restated the segment information for the year ended December 31, 2019.

Since there are no intersegment sales of inventory or depreciable assets, there is no unrealized intersegment profit to be eliminated on consolidation. The Group principally operates its businesses in Korea and the revenue amounts earned outside of Korea are immaterial. Therefore, no entity-wide geographical information is presented.

No single customer contributed 10% or more to the Group’s total revenue for the years ended December 31, 2020 and 2019.

7. Trade and Other Receivables, Continued

(3) The Group applies the practical expedient that allows the Group to estimate the loss allowance for accounts receivable – trade at an amount equal to the lifetime expected credit losses. The expected credit losses include the forward-looking information. To make the assessment, the Group uses its historical credit loss experience over the past three years and classified the accounts receivable – trade by their credit risk characteristics and days overdue. Details of loss allowance on accounts receivable – trade as of December 31, 2020 are as follows:

(In millions of won)
		Less than 6 months			6 months ~ 1 year			1 ~ 3 years			More than 3 years
Telecommunications service revenue	Expected credit loss rate		2.04	%		70.29	%		86.21	%		99.18	%
	Gross amount	W	1,400,316			49,583			127,275			25,195
	Loss allowance		28,574			34,854			109,727			24,988
Other revenue	Expected credit loss rate		2.82	%		77.52	%		61.76	%		56.19	%
	Gross amount	W	802,081			6,753			8,250			59,398
	Loss allowance		22,652			5,235			5,095			33,373

As the Group is a wireless and fixed-line telecommunications service provider, the Group’s financial assets measured at amortized cost primarily consist of receivables from numerous individual customers, and, therefore, no significant credit concentration risk arises.

Receivables related to other revenue mainly consist of receivables from corporate customers. The Group transacts only with corporate customers with credit ratings that are considered to be low at credit risk. In addition, the Group is not exposed to significant credit concentration risk as the Group regularly assesses their credit risk by monitoring their credit rating. While the contract assets are under the impairment requirements, no significant credit risk has been identified.

(2) Details of the impairment testing of Goodwill as of December 31, 2020 is as follows:

Goodwill is allocated to the following CGUs for the purpose of impairment testing.

• goodwill related to Shinsegi Telecom, Inc.(*1): Cellular services;

• goodwill related to SK Broadband Co., Ltd.(*2): Fixed-line telecommunication services;

• goodwill related to Life & Security Holdings Co., Ltd.(*3): Security services; and

• other goodwill: Security services and other.

(*1) Goodwill related to merger of Shinsegi Telecom, Inc.

The recoverable amount of the CGU is based on its value in use calculated by applying the annual discount rate of 6.3%(4.9% in prior year) to the estimated future cash flows based on financial budgets for the next five years. An annual growth rate of (-)0.2%((-)0.6% in prior year) was applied for the cash flows expected to be incurred after five years and is not expected to exceed the long-term wireless telecommunication industry growth rate. Management of the Group does not expect the total carrying amount of the CGU will exceed the total recoverable amount due to reasonably possible changes from the major assumptions used to estimate the recoverable amount.

(*2) Goodwill related to acquisition of SK Broadband Co., Ltd.

The recoverable amount of the CGU is based on its value in use calculated by applying the annual discount rate of 6.9%(5.0% in prior year) to the estimated future cash flows based on financial budgets for the next five years. An annual growth rate of 1.0%(1.0% in prior year) was applied for the cash flows expected to be incurred after five years and is not expected to exceed the long-term fixed-line telecommunication industry growth rate. Management of the Group does not expect the total carrying amount of the CGU will exceed the total recoverable amount due to reasonably possible changes from the major assumptions used to estimate the recoverable amount.

(*3) Goodwill related to acquisition of Life & Security Holdings Co., Ltd.

The recoverable amount of the CGU is based on its value in use, which is estimated based on using key assumptions including estimated revenue growth rates, labor costs, annual growth rate applied for the cash flows expected to be incurred after five years (“perpetual growth rate”), and discount rate. The discount rate applied for future cash flows based on financial budgets for the next five years is 7.1% (7.29% in 2019). The estimated revenue growth rates and labor costs are based on past performance, business plans and its expectation of future market changes.

In addition, an annual growth rate of 1.0% (1.0% in 2019) was applied for the cash flows expected to be incurred after five years and does not exceed the long-term growth rate in the security service industry. Management of the Group does not expect the total carrying amount of the CGU will exceed the total recoverable amount as a result of reasonably possible changes to these assumptions.

(4) In relation to the business acquisition by SK Broadband Co., Ltd. (see note 12 (1)) in 2020, the Parent Company has entered into a shareholders’ agreement with the shareholders of the acquirees. Pursuant to the agreement, when certain conditions are met within a period of time subsequent to the business combination, the shareholders of the acquirees can exercise their drag-along rights and require the Parent Company to sell its shares in SK Broadband Co., Ltd. Should the shareholders exercise their drag-along rights, the Parent Company also can exercise its call options over the shares held by those shareholders. The Group recognized a derivative financial liability of W320,984 million for the rights included in the shareholders’ agreement as of December 31, 2020.

The fair value of SK Broadband Co., Ltd.’s common stock (post-merger) was estimated using 5-year projected cash flows discounted at 6.9% per annum. The fair value of the derivative financial liability was determined by using the Binomial Model based on various assumptions including the price of common stock and its price fluctuations. The difference in fair values between the acquisition date and December 31, 2020 is insignificant. The significant unobservable inputs used in the fair value measurement and inter-relationship between significant unobservable inputs and fair value measurement are as below:

Significant unobservable inputs	Correlations between inputs and fair value measurements
Fair value of SK Broadband Co., Ltd.’s common stock	The estimated fair value of derivative liabilities would decrease (increase) if the fair value of common stock would increase (decrease)
Volatility	The estimated fair value of derivative liabilities would decrease (increase) if the volatility of stock price increase (decrease)

37. Financial Risk Management

(1) Financial risk management

The Group is exposed to credit risk, liquidity risk and market risk. Market risk is the risk related to the changes in market prices, such as foreign exchange rates and interest rates. The Group implements a risk management system to monitor and manage these specific risks.

The Group’s financial assets consist of cash and cash equivalents, financial instruments, investment securities, accounts receivable – trade and other, etc. Financial liabilities consist of accounts payable – trade and other, borrowings, debentures, lease liabilities and others.

1) Market risk

(i) Currency risk

The Group incurs exchange position due to revenue and expenses from its global operations. Major foreign currencies where the currency risk occur are USD, EUR and JPY. The Group determines the currency risk management policy after considering the nature of business and the presence of methods that mitigate the currency risk for each Group entities. Currency risk occurs on forecasted transactions and recognized assets and liabilities which are denominated in a currency other than the functional currency of each Group entity. The Group manages currency risk arising from business transactions by using currency forwards, etc.

Monetary assets and liabilities denominated in foreign currencies as of December 31, 2020 are as follows:

(In millions of won, thousands of foreign currencies)
	Assets				Liabilities
	Foreign currencies		Won equivalent		Foreign currencies		Won equivalent
USD		84,581	W	92,025		1,541,544	W	1,677,200
EUR		10,903		14,591		2,519		3,370
JPY		672,311		7,088		22,778		240
Others		—		2,702		—		606
			W	116,406			W	1,681,416

In addition, the Group has entered into cross currency swaps to hedge against currency risk related to foreign currency borrowings and debentures. (See note 22)

As of December 31, 2020 a hypothetical change in exchange rates by 10% would have increased (decreased) the Group’s income before income tax as follows:

(In millions of won)
	If increased by 10%		If decreased by 10%
USD	W	5,507		(5,507	)
EUR		1,122		(1,122	)
JPY		685		(685	)
Others		210		(210	)
	W	7,524		(7,524	)

37. Financial Risk Management, Continued

1) Market risk, Continued

(ii) Interest rate risk

The interest rate risk of the Group arises from borrowings, debenture and long-term payables – other. Since the Group’s interest bearing assets are mostly fixed-interest bearing assets, the Group’s revenue and operating cash flows from the interest-bearing assets are not influenced by the changes in market interest rates.

The Group performs various analysis to reduce interest rate risk and to optimize its financing. To minimize risks arising from changes in interest rates, the Group takes various measures such as refinancing, renewal, alternative financing and hedging.

As of December 31, 2020, the floating-rate borrowings and bonds of the Group are W121,750 million and W326,400 million, respectively, and the Group has entered into interest rate swap agreements, as described in note 22, for the most of all floating-rate borrowings and debentures to hedge interest rate risk. If the interest rate increases (decreases) 1% with all other variables held constant, income before income taxes would change by W470 million in relation to interest expenses on floating-rate borrowings that are exposed to interest rate risk, which would also change the year-end balance of shareholder’s equity by the same amount.

As of December 31, 2020, the floating-rate long-term payables – other are W1,626,040 million. If the interest rate increases (decreases) 1% with all other variables held constant, income before income taxes for the year ended December 31, 2020 would change by W 16,260 million in relation to floating-rate long-term payables - other that are exposed to interest rate risk.

A fundamental reform of major interest rate benchmarks is being undertaken globally, including the replacement of some interbank offered rates (“IBOR”s) with alternative nearly risk-free rates (referred to as “IBOR reform”). The Group has exposures to IBORs on its financial instruments that will be replaced or reformed as part of these market-wide initiatives. There is uncertainty over the timing and the methods of transition in some jurisdictions that the Group operates in. The Group anticipates that IBOR reform will impact its risk management and hedge accounting.

Derivatives

The Group holds interest rate swaps for risk management purposes which are designated in cash flow hedging relationships. The interest rate swaps have floating legs that are indexed to LIBOR. The Group’s derivative instruments are governed by contracts based on the International Swaps and Derivatives Association (“ISDA”)’s master agreements.

ISDA is currently reviewing its standardized contracts in the light of IBOR reform and plans to amend certain floating-rate options in the 2006 ISDA definitions to include fallback clauses that would apply on the permanent discontinuation of certain key IBORs. ISDA is expected to publish an IBOR fallback supplement to amend the 2006 ISDA definitions and an IBOR fallback protocol to facilitate multilateral amendments to include the amended floating-rate options in derivative transactions that were entered into before the date of the supplement. The Group currently plans to adhere to the protocol if and when it is finalized and to monitor whether its counterparties will also adhere. If this plan changes or there are counterparties who will not adhere to the protocol, the Group will negotiate with them bilaterally about including new fallback clauses.

Hedge accounting

The Group has evaluated the extent to which its cash flow hedging relationships are subject to uncertainty driven by IBOR reform as of December 31, 2020. The Group’s hedged items and hedging instruments continue to be indexed to LIBOR. These benchmark rates are quoted each day and the IBOR cash flows are exchanged with counterparties as usual.

However, the Group’s LIBOR cash flow hedging relationships extend beyond the anticipated cessation date for LIBOR. The Group expects that LIBOR will be discontinued after the end of 2021. As of December 31, 2020, the Group has not determined the alternative interest rate benchmark to LIBOR and there is uncertainty about when and how replacement may occur with respect to the relevant hedged items and hedging instruments. Such uncertainty may impact the hedging relationship. The Group applies the amendments to K-IFRS No. 1109, Financial Instruments issued in 2020 to those hedging relationships directly affected by IBOR reform.

Hedging relationships impacted by IBOR reform may experience ineffectiveness attributable to market participants’ expectations of when the shift from the existing IBOR benchmark rate to an alternative benchmark interest rate will occur. This transition may occur at different times for the hedged item and hedging instrument, which may lead to hedge ineffectiveness. The Group has measured its hedging instruments indexed to LIBOR using available quoted market rates for LIBOR-based instruments of the same tenor and similar maturity and has measured the cumulative change in the present value of hedged cash flows attributable to changes in LIBOR on a similar basis.

2) Credit risk

The maximum credit exposure as of December 31, 2020 and 2019 are as follows:

(In millions of won)
	December 31, 2020		December 31, 2019
Cash and cash equivalents	W	1,369,423		1,270,572
Financial instruments		1,427,845		831,637
Investment securities		4,154		13,548
Accounts receivable – trade		2,214,353		2,247,895
Contract assets		148,281		191,858
Loans and other receivables		1,738,003		1,668,557
Derivative financial assets		164,695		150,960
	W	7,066,754		6,375,027

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. To manage credit risk, the Group evaluates the credit worthiness of each customer or counterparty considering the party’s financial information, its own trading records and other factors. Based on such information, the Group establishes credit limits for each customer or counterparty.

(i) Accounts receivable – trade and contract assets

The Group establishes a loss allowance in respect of accounts receivable – trade and contract assets. The main components of this allowance are a specific loss component that relates to individually significant exposures and a collective loss component established for groups of similar assets in respect of losses that are expected to occur. The collective loss allowance is determined based on historical data of collection statistics for similar financial assets. Details of changes in loss allowance during the year ended December 31, 2020 are included in note 7.

(ii) Debt investments

The credit risk arises from debt investments included in W1,427,845 million of financial instruments, W4,154 million of investment securities and W1,738,003 million of loans and other receivables. To limit the exposure to this risk, the Group transacts only with financial institutions with credit ratings that are considered to be low credit risk.

Most of the Group’s debt investments are considered to have a low risk of default and the borrower has a strong capacity to meet its contractual cash flow obligations in the near term. Thus the Group measured the loss allowance for the debt investments at an amount equal to 12-month expected credit losses.

Meanwhile, the Group monitors changes in credit risk at each reporting date. The Group recognized the loss allowance at an amount equal to lifetime expected credit losses when the credit risk on the debt investments is assumed to have increased significantly if it is more than 30 days past due.

The Group’s maximum exposure to credit risk is equal to each financial asset’s carrying amount. The gross carrying amounts of each financial asset except for the accounts receivable – trade and derivative financial assets as of December 31, 2020 are as follows.

(In millions of won)
	Financial assets at FVTPL		Financial assets at FVOCI		At amortized cost
					12-month ECL			Lifetime ECL – not credit impaired			Lifetime ECL – credit impaired

The above information does not include fair values of financial assets and liabilities of which fair values have not been measured as carrying amounts are reasonable approximation of fair values.

Fair value of the financial instruments that are traded in an active market (financial assets at FVOCI) is measured based on the bid price at the end of the reporting date.

The Group uses various valuation methods for determination of fair value of financial instruments that are not traded in an active market. Derivative financial contracts and long-term liabilities are measured using the discounted present value methods. Other financial assets are determined using the methods such as discounted cash flow and market approach. Inputs used to such valuation methods include swap rate, interest rate, and risk premium, and the Group performs valuation using the inputs which are consistent with natures of assets and liabilities measured.

Interest rates used by the Group for the fair value measurement as of December 31, 2020 are as follows:

	Interest rate
Derivative instruments		0.14% ~ 3.90%
Borrowings and debentures		0.99% ~ 2.21%
Long-term payables – other		0.90% ~ 1.72%
