Basis of Preparation | 2. Basis of Preparation (1) Statement of compliance These consolidated financial statements were prepared in accordance with International Financial Reporting Standards (“IFRS”), as issued by the International Accounting Standards Board (“IASB”). These consolidated financial statements were authorized for issue by the Board of Directors on February 2, 2021 for statutory shareholders’ approval purpose, and re-authorized for issue by management in connection with the filing with the U.S. Securities Exchange Commission on April 29, 2021. (2) 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 (3) 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. (4) Use of estimates and judgments The preparation of the consolidated financial statements in conformity with 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), determination of stand-alone selling prices. 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 36), 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 (17) and 20), measurement of defined benefit liabilities (notes 4 (16) and 21), and recognition of deferred tax assets (liabilities) (notes 4 (24) and 32). 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 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 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 36. |

Changes in accounting policies | 3. Changes in accounting policies The Group has initially adopted the amendments to the ’Definition of a Business’(Amendments to IFRS 3, Business Combination Financial Instruments, Financial Instrument — Recognition and Measurement, Financial Instruments — Disclosures) The Group applied Definition of a Business (Amendments to IFRS 3) 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 36 for related disclosures about risks and hedge accounting. The Group has applied IFRS 16, Leases from January 1, 2019 using the modified retrospective method with the cumulative effect of initially applying this standard recognized as an adjustment to the retained earnings as at January 1, 2019. Accordingly, the comparative information presented for 2018 has been presented, as previously reported, under IAS 17, Leases and has not been restated. 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 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 The Group has retrospectively applied the changes in its accounting policies in connection with the IFRIC agenda decision in accordance with IAS 8, Accounting Policies, Changes in Accounting Estimates and Errors The following table summarizes the impacts of the change in accounting policies on the Group’s consolidated financial statements on the current and prior period.

Significant Accounting Policies | 4. Significant Accounting Policies The significant accounting policies applied by the Group in the preparation of its consolidated financial statements in accordance with IFRS are included below. The significant accounting policies applied by the Group in these consolidated financial statements have been consistently applied for all periods presented, except for the changes described in note 3 and below. (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 (a) 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, identical to the measurement of identifiable net assets acquired at fair value. The difference between the acquired company’s fair value and the consideration transferred is accounted for 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 excluding costs to issue debt or equity securities recognized based on IAS 32 and IFRS 9. Consideration transferred does not include the amount settled in relation to the pre-existing 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. (b) Non-controlling Non-controlling 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. (c) 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. (d) 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. (e) 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. The investment in an associate and a joint venture is impaired if objective evidence indicates that a loss event has occurred after the initial recognition of the asset, and that the loss event had a negative effect on the estimated future cash flows of that asset that can be estimated reliably. • significant financial difficulty of the associate or joint venture; • a breach of contract, such as a default or delinquency in payments by the associate or joint venture; • the entity, for economic or legal reasons relating to its associate’s or joint venture’s financial difficulty, granting to the associate or joint venture a concession that the entity would not otherwise consider; • it becoming probable that the associate or joint venture will enter bankruptcy or other financial reorganization; or • the disappearance of an active market for the net investment because of financial difficulties of the associate or joint venture. (f) 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. (g) 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 (a) 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. (b) 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. 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 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 polices apply 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. (c) 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 assets. (d) 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. (e) 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 it 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 is 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, including 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. (a) 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 cash flow risk of 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 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. 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. (b) 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 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 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 Right-of-use 1 ~ 50 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. 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 The carrying amounts of the Group’s non-financial non-current 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 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 - Policies applicable from January 1, 2019 The Group has applied IFRS 16, Leases from January 1, 2019 using the modified retrospective method with the cumulative effect of initially applying this standard recognized as an adjustment to the retained earnings as at January 1, 2019. Accordingly, the comparative information presented for 2018 has been presented, as previously reported, under IAS 17, Leases and has not been restated. A contract is or contains a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. To assess whether a contract transfers the right to control the identified asset, the Group uses the definition of a lease in IFRS 16, Leases. (a) 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 non-lease The Group recognizes a right-of-use right-of-use The right-of-use straight-line right-of-use right-of-use right-of-use 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 • 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 • 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 or termination option or if there is a revised in-substance When the lease liability is remeasured in this way, a corresponding adjustment is made to the carrying amount of the right-of-use right-of-use The Group presents right-of-use The Group has elected not to recognize right-of-use low-value (b) 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 sub-lease right-of-use sub-lease If an arrangement contains lease and non-lease The Group applies derecognition and impairment requirements in IFRS 9 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) Leases — Policies applied before January 1, 2019 The Group classifies and accounts for leases as either a finance or operating lease, depending on the terms. Leases under which the Group assumes substantially all of the risks and rewards of ownership are classified as finance leases. All other leases are classified as operating leases. (a) Finance leases — lessee At the commencement of the lease term, the Group recognizes as finance assets and finance liabilities in its consolidated statement of financial position, the lower amount of the fair value of the leased property and the present value of the minimum lease payments, each determined at the inception of the lease. Any initial direct costs are added to the amount recognized as an asset. Minimum lease payments are apportioned between the finance cost and the reduction of the outstanding liability. The finance cost is allocated to each period during the lease term so as to produce a constant periodic rate of interest on the remaining balance of the liability. Contingent rents are charged as expenses in the periods in which they are incurred. The depreciable amount of a leased asset is allocated to each accounting period during the period of expected use on a systematic basis consistent with the depreciation policy the Group adopts for depreciable assets that are owned. If there is no reasonable certainty that the Group will obtain ownership by the end of the lease term, the asset is fully depreciated over the shorter of the lease term and its useful life. The Group reviews to determine whether the leased assets are impaired at the reporting date. (b) Operating leases Leases where the lessor retains a significant portion of the risks and rewards of ownership are classified as operating leases. Payments made under operating leases (net of any incentives received from the lessor) are recognized in profit or loss on a straight-line basis over the lease term. (c) Determining whether an arrangement contains a lease Determining whether an arrangement is, or contains, a lease is based on the substance of the arrangement and requires an assessment of whether fulfillment of the arrangement is dependent on the use of a specific asset and the arrangement conveys a right to use the asset. At inception or reassessment of the arrangement, the Group separates payments and other consideration required by such an arrangement into those for the lease and those for other elements on the basis of their relative fair values. If the Group concludes for a financial lease that it is impracticable to separate the payments reliably, the Group recognizes an asset and a liability at an amount equal to the fair value of the underlying asset that was identified as the subject of the lease. Subsequently, the liability is reduced as payments are made and an imputed finance charge on the liabili |

(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 ~ 1 year 1 ~ 3 years More than Telecommunications service revenue Expected credit loss rate 2.04 % 70.29 % 86.21 % 99.18 % Gross amount ₩ 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 ₩ 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. |

(*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 2019) 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 2019) 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. (3) Details of the changes in goodwill for the years ended December 31, 2020 and 2019 are as follows: (In millions of won) 2020 2019 Beginning balance ₩ 2,949,530 2,938,563 Acquisition(*1) 408,531 30,962 Impairment loss(*2) (519 ) (21,065 ) Other (18 ) 1,070 Ending balance ₩ 3,357,524 2,949,530 (*1) It consists of goodwill recognized as SK Broadband Co., Ltd., a subsidiary of the Parent Company, merged with Tbroad Co., Ltd. and two other companies and goodwill recognized from ADT CAPS Co., Ltd.’s acquisition of security equipment construction and security services business from SK hystec inc. during the year ended December 31, 2020. (See Note 12) (*2) As a result of the impairment test on DREAMUS COMPANY and Incross Co., Ltd., the carrying value of the CGU exceeds the recoverable amount, thus the Group recognized ₩519 million of impairment loss. As of December 31, 2020 and 2019, accumulated impairment losses are ₩85,764 million and ₩85,245 million, respectively. |

Financial Risk Management | 36. 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 others, etc. Financial liabilities consist of accounts payable — 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 USD 84,581 ₩ 92,025 1,541,544 ₩ 1,677,200 EUR 10,903 14,591 2,519 3,370 JPY 672,311 7,088 22,778 240 Others — 2,702 — 606 ₩ 116,406 ₩ 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 (reduced) the Group’s income before income tax as follows: (In millions of won) If increased by 10% If decreased by 10% USD ₩ 5,507 (5,507 ) EUR 1,122 (1,122 ) JPY 685 (685 ) Others 210 (210 ) ₩ 7,524 (7,524 ) (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 ₩121,750 million and ₩326,400 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 ₩470 million in relation to interest expenses on floating-rate borrowings that are exposed to interest rate risk, which would also change the year-end As of December 31, 2020, the floating-rate long-term payables – other are ₩1,626,040 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 ₩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 market-wide 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 IFRS 9, Financial Instruments 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 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 ₩ 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 ₩ 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 ₩1,427,845 million of financial instruments, ₩4,154 million of investment securities and ₩1,738,003 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 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.

Impairment on cash and cash equivalents has been measured on a 12-month 3) Liquidity risk The Group’s approach to managing liquidity is to ensure that it will always maintain sufficient cash and cash equivalents balances and have enough liquidity through various committed credit lines.

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% 3) There have been no transfers between Level 2 and Level 1 for year ended December 31, 2020.

In connection with those legal claims and litigation for which no provision was recognized, management does not believe the Group has a present obligation, nor is it expected any of these claims or litigation will have a significant impact on the Group’s financial position or operating results in the event an outflow of resources is ultimately necessary. Meanwhile, the pending litigation over the validity of partnership contract that SK Planet Co., Ltd., a subsidiary of the Parent Company, was involved as the defendant (Plaintiff: Nonghyup Bank) was settled by the agreement between the parties during the year ended December 31, 2018. As a result of the settlement, the credit card business partnership between SK Planet Co., Ltd. and Nonghyup Bank will be maintained until April 2021, and the Group is obligated to pay the commission fees based on the customers’ credit card usage until September 2021, the expiration date of the credit cards. The Group determined that the contract and the subsidiary agreements meet the definition of an onerous contract according to IAS 37, for which the Group recognized provisions with the best estimate of the expenditure required to settle the present obligation at the end of the reporting period. In this regard, ₩18,717 million are recognized as current provisions as of December 31, 2020. (3) Accounts receivable from sale of handsets The sales agents of the Parent Company sell handsets to the Parent Company’s subscribers on an installment basis. The Parent Company entered into comprehensive agreements to purchase accounts receivables from handset sales with retail stores and authorized dealers and to transfer the accounts receivables from handset sales to special purpose companies which were established with the purpose of liquidating receivables, respectively. The accounts receivables from sale of handsets amounting to ₩571,004 million and ₩646,837 million as of December 31, 2020 and 2019, respectively, which the Parent Company purchased according to the relevant comprehensive agreement are recognized as accounts receivable – other and long-term accounts receivable — other. |

Operating segments | (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. |
Basis of consolidation | (2) Basis of consolidation (a) 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, identical to the measurement of identifiable net assets acquired at fair value. The difference between the acquired company’s fair value and the consideration transferred is accounted for 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 excluding costs to issue debt or equity securities recognized based on IAS 32 and IFRS 9. Consideration transferred does not include the amount settled in relation to the pre-existing 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. (b) Non-controlling Non-controlling 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. (c) 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. (d) 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. (e) 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. The investment in an associate and a joint venture is impaired if objective evidence indicates that a loss event has occurred after the initial recognition of the asset, and that the loss event had a negative effect on the estimated future cash flows of that asset that can be estimated reliably. • significant financial difficulty of the associate or joint venture; • a breach of contract, such as a default or delinquency in payments by the associate or joint venture; • the entity, for economic or legal reasons relating to its associate’s or joint venture’s financial difficulty, granting to the associate or joint venture a concession that the entity would not otherwise consider; • it becoming probable that the associate or joint venture will enter bankruptcy or other financial reorganization; or • the disappearance of an active market for the net investment because of financial difficulties of the associate or joint venture. (f) 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. (g) 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. |
Cash and cash equivalents | (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. |
Inventories | (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. |
Derivative financial instruments, including hedge accounting | (6) Derivative financial instruments, including 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. (a) 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 cash flow risk of 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 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. 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. (b) 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. |
Property and equipment | (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 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 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 Right-of-use 1 ~ 50 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. |
Borrowing costs | (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. |
Intangible assets | (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. 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. |
Government grants | (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. |
Impairment of non-financial assets | (11) Impairment of non-financial The carrying amounts of the Group’s non-financial non-current 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 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. |
Leases - Policies applicable from January 1, 2019 | (12) Leases - Policies applicable from January 1, 2019 The Group has applied IFRS 16, Leases from January 1, 2019 using the modified retrospective method with the cumulative effect of initially applying this standard recognized as an adjustment to the retained earnings as at January 1, 2019. Accordingly, the comparative information presented for 2018 has been presented, as previously reported, under IAS 17, Leases and has not been restated. A contract is or contains a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. To assess whether a contract transfers the right to control the identified asset, the Group uses the definition of a lease in IFRS 16, Leases. (a) 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 non-lease The Group recognizes a right-of-use right-of-use The right-of-use straight-line right-of-use right-of-use right-of-use 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 • 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 • 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 or termination option or if there is a revised in-substance When the lease liability is remeasured in this way, a corresponding adjustment is made to the carrying amount of the right-of-use right-of-use The Group presents right-of-use The Group has elected not to recognize right-of-use low-value (b) 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 sub-lease right-of-use sub-lease If an arrangement contains lease and non-lease The Group applies derecognition and impairment requirements in IFRS 9 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’. |

Non-derivative financial liabilities | (15) Non-derivative The Group classifies non-derivative (a) 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. (b) Other financial liabilities Non-derivative (c) 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 |
Employee benefits | (16) Employee benefits (a) 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. (b) 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. (c) 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. (d) 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. (e) 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. |
Provisions | (17) 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. |
Transactions in foreign currencies | (18) Transactions in foreign currencies (a) Foreign currency transactions Transactions in foreign currencies are translated to the functional currency of 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 Foreign currency differences arising on retranslation are recognized in profit or loss, except for differences arising on the retranslation of available-for-sale (b) 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 |
Share capital | (19) 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. |
Hybrid bond | (20) 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 part y. |
Share-based Payment | (21) 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 award s. The amount recognized as an expense is adjusted to reflect the number of awards for which the related service and non-market non-market 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. |
Finance income and finance costs | (23) 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. |
Income taxes | (24) 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 (a) 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 non-deductible (b) 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. (c) Uncertainty over income tax treatments The Group assesses the uncertainty over income tax treatments pursuant to IAS 12. 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 |
Earnings per share | (25) 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. |
Standards issued but not yet effective | (26) 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 IFRS 9, Financial Instruments Financial Instrument—Recognition and Measurement Financial Instruments- Disclosures Insurance Contracts Leases The amendments address issued 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 IFRS 9, Financial Instruments Financial Instrument- Recognition and Measurement Financial Instruments- Disclosures Insurance Contracts Leases The amendment 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 ₩326,400 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 requirement 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- • 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 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 consolidated financial statements. • COVID-19-Related • Property, Plant and Equipment: Proceeds before Intended Use (Amendments to IAS 16). • Reference to Conceptual Framework (Amendments to IFRS 3). • Classification of Liabilities as Current or Non-current • IFRS 17 Insurance Contracts |

Financial assets - Policies applicable from January 1, 2018 | (5) Non-derivative (a) 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. (b) 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. 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 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 polices apply 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. (c) 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 assets. (d) 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. (e) 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 it 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 is 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. |
Leases - Policies applicable from January 1, 2019 | (13) Leases — Policies applied before January 1, 2019 The Group classifies and accounts for leases as either a finance or operating lease, depending on the terms. Leases under which the Group assumes substantially all of the risks and rewards of ownership are classified as finance leases. All other leases are classified as operating leases. (a) Finance leases — lessee At the commencement of the lease term, the Group recognizes as finance assets and finance liabilities in its consolidated statement of financial position, the lower amount of the fair value of the leased property and the present value of the minimum lease payments, each determined at the inception of the lease. Any initial direct costs are added to the amount recognized as an asset. Minimum lease payments are apportioned between the finance cost and the reduction of the outstanding liability. The finance cost is allocated to each period during the lease term so as to produce a constant periodic rate of interest on the remaining balance of the liability. Contingent rents are charged as expenses in the periods in which they are incurred. The depreciable amount of a leased asset is allocated to each accounting period during the period of expected use on a systematic basis consistent with the depreciation policy the Group adopts for depreciable assets that are owned. If there is no reasonable certainty that the Group will obtain ownership by the end of the lease term, the asset is fully depreciated over the shorter of the lease term and its useful life. The Group reviews to determine whether the leased assets are impaired at the reporting date. (b) Operating leases Leases where the lessor retains a significant portion of the risks and rewards of ownership are classified as operating leases. Payments made under operating leases (net of any incentives received from the lessor) are recognized in profit or loss on a straight-line basis over the lease term. (c) Determining whether an arrangement contains a lease Determining whether an arrangement is, or contains, a lease is based on the substance of the arrangement and requires an assessment of whether fulfillment of the arrangement is dependent on the use of a specific asset and the arrangement conveys a right to use the asset. At inception or reassessment of the arrangement, the Group separates payments and other consideration required by such an arrangement into those for the lease and those for other elements on the basis of their relative fair values. If the Group concludes for a financial lease that it is impracticable to separate the payments reliably, the Group recognizes an asset and a liability at an amount equal to the fair value of the underlying asset that was identified as the subject of the lease. Subsequently, the liability is reduced as payments are made and an imputed finance charge on the liability is recognized using the Group’s incremental borrowing rate of interest. |
Revenue — Policies applicable from January 1, 2018 | (22) Revenue (a) 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. (b) 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. (c) 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. (d) 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. (e) Consideration payable to a customer Based on the subscription contract, a customer who uses the Group’s wireless telecommunications services may receive 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. |
