Independent Auditors’ Report

Based on a report originally issued in Korean

To the Board of Directors and Shareholders of

SK Telecom Co., Ltd.:

Opinion

We have audited the accompanying consolidated financial statements of SK Telecom Co., Ltd. and its subsidiaries (the “Group”) which comprise the consolidated statements of financial position as of December 31, 2018 and 2017, and the consolidated statements of income, comprehensive income, changes in equity and cash flows for the years then ended, and notes to the financial statements, comprising significant accounting policies and other explanatory information.

In our opinion, the accompanying consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Group as of December 31, 2018 and 2017, and its consolidated financial performance and its consolidated cash flows for the years then ended in accordance with Korean International Financial Reporting Standards (“K-IFRS”).

Basis for Opinion

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

Key Audit Matters

Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the consolidated financial statements as of and for the year ended December 31, 2018. These matters were addressed in the context of our audit of the consolidated financial statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters.

1. Accuracy of Revenue

As described in notes 3 and 4 of the consolidated financial statements, the Group has initially adopted K-IFRS No.1115, Revenue from Contracts with Customers (“K-IFRS No. 1115”), from January 1, 2018 and the Group has taken an exemption not to restate the consolidated financial statements as of and for the year ended December 31, 2017, presented for comparative purposes, in accordance with transition requirements of the standards. The financial impacts of adopting K-IFRS No. 1115 are discussed in note 3. The Group’s consolidated revenue is primarily related to the Group’s cellular and fixed-line telecommunications segments.

The Group’s revenue recognition is based on data from complex information technology systems as the Group provides a variety of telecommunications services at various rate plans to numerous subscribers which involves high volume of transactions with subscribers. In addition, the effect of changes in accounting policies upon the adoption of K-IFRS No. 1115 is significant to the consolidated financial statements. Such changes include the changes in the amount of revenue recognition related to the allocation of considerations for each performance obligation when the Group provides wireless telecommunications services and sells wireless handset to a same subscriber. The determination of stand-alone selling prices involving complex judgments applied by management. Therefore, we have identified the accuracy of revenue recognition in the Group’s cellular and fixed-line telecommunications segments as a key audit matter due to the complexity of IT systems involved and management judgments involved in the application of the new revenue recognition standard.

Table of Contents

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

• Testing certain internal controls relating to the Group’s revenue recognition process, including evaluation of the environment of the IT systems supporting the accounting for revenue, including data records, rating and invoicing systems.

• Testing the reconciliation of the Group’s revenue among rating system, billing system and the general ledger.

• Inspecting a sample of contracts with subscribers to assess the Group’s revenue recognition policies upon initial adoption of K-IFRS No. 1115 based on the terms and conditions as set out in the contracts, with reference to the requirements of the relevant accounting standards.

• Assessing whether the Group’s determination of accounting treatments for bundled transactions for wireless telecommunication services and sales of wireless handsets are made in accordance with relevant accounting standards.

• Testing the accuracy of the stand-alone selling price by comparing to the published rates for each wireless handset and wireless telecommunications services on a sample basis.

• Testing the accuracy of the allocation of considerations to revenues from the Group’s wireless telecommunications services and sale of wireless handsets by performing recalculation.

• Testing the mathematical accuracy of the cumulative effect of initially applying K-IFRS No. 1115 in relation to multiple performance obligations as of January 1, 2018 by performing recalculation.

1. Recognition of Incremental Costs of Obtaining a Contract

As described in notes 3 and 8 of the consolidated financial statements, the Group incurs costs, such as commissions to retails stores and authorized dealers based on the number of subscribers retained and newly obtained. Costs that would not have been paid if there had been no binding new or renewed contracts with subscribers are capitalized and amortized over the estimated service periods. As of December 31, 2018, capitalized costs to obtain contracts amount to W 2,377,599 million.

Determination of whether certain costs of obtaining a contract could be capitalized as well as the amortization period involves a number of key judgments made by the Group and the incremental costs of obtaining contracts are significant in the Group’s consolidated financial statements. Therefore we have identified the recognition of incremental costs of obtaining contracts as a key audit matter.

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

• Testing certain controls relating to the Group’s process to account for incremental costs of obtaining contracts.

• Obtaining an understanding of the marketing programs communicated to retail stores and authorized dealers and assessing the Group’s determination of whether the costs should be capitalized with reference to the requirements of the relevant accounting standards. In addition, on a sample basis, we also compared the capitalized costs with payments to retail stores and authorized dealers.

• Testing the mathematical accuracy of the cumulative effect of initially applying K-IFRS No. 1115 in relation to the incremental costs of obtaining contracts as of January 1, 2018 by performing recalculation.

• Assessing the estimated service periods that are used in amortizing the capitalized incremental costs of obtaining contracts by testing the completeness and accuracy of data used in the analysis, and by comparing the data used in estimating the estimated service periods with the Group’s historical subscriber churn rates and publicly available statistical data.

1. Assessment of Goodwill Impairment

As described in note 4 of the consolidated financial statements, the Group performs impairment test for goodwill at least annually by comparing the recoverable amount and the carrying amount of a cash generating unit (“CGU”) to which goodwill is allocated. The amount of goodwill that is allocated to the CGUs in cellular and fixed-line segments is W 1,664,679 million as of December 31, 2018.

In carrying out the impairment assessment of goodwill, management determined the recoverable amount based on the value-in-use (“VIU”). Determining the VIU of the above CGUs involves significant judgments in estimating the expected future cash flows including the estimates of revenue, operating expense, perpetual growth rate, and discount rate for each CGU. Considering the significant degree of the judgment in estimating the VIU of the cellular and fixed-line telecommunication CGUs and the potential impact of the impairment on the Group’s consolidated financial statements, we identified the assessment of goodwill impairment as a key audit matter.

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

• Testing certain internal controls over the Group’s process to estimate value-in-use.

• Engaging our internal valuation specialists to assist us in evaluating the key assumptions used to determine the VIU for each CGU which included the estimated revenue, operating expenses and perpetual growth rate by comparison with the financial budgets approved by the management, historical performance and industry reports and in assessing the appropriateness of discount rate used by comparison with our expectation based on market data.

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

• Comparing the cash flow forecasts prepared in prior year with the actual results to assess the Group’s ability to accurately forecast.

1. Acquisition of Life & Security Holdings Co., Ltd.

As described in note 12 to the consolidated financial statements, during 2018, the Group obtained control of Life & Security Holdings Co., Ltd. (“LSH”) for W 696,665 million in cash. In connection with the acquisition of LSH, the fair value of identifiable intangible assets recognized amounted to W 1,019,503 million.

K-IFRS No. 1103 requires the Group, the acquirer, to recognize the acquiree’s identifiable assets, including intangible assets not previously recognized, and liabilities assumed at their fair value as of the acquisition date. Determining the fair value of the identifiable intangible assets requires management’s significant judgments in determining the valuation methodologies and estimating the expected future cash flows including the estimates of revenue, attrition rate, royalty rate, operating expense, perpetual growth rate, and discount rate. Considering the significant degree of the judgment in measuring the fair value of identifiable net assets, we identified the identification of intangible assets and measurement of their fair value for intangible assets recognized in the acquisition of LSH as a key audit matter.

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

• Engaging our internal valuation specialists to assist us in assessing the valuation methodologies adopted by the Group with reference to industry standards and the requirements of the relevant accounting standards.

• Engaging our internal valuation specialists to evaluate the discount rate applied by comparison with our expectation based on market data and the key assumptions used in estimating future cash flows, which included the estimated revenue, operating expenses, and perpetual growth rate by comparing with the financial budgets approved by the acquiree’s management, historical performance and industry reports.

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

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

In preparing the consolidated financial statements, management is responsible for assessing the Group’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless management either intends to liquidate the Group or to cease operations, or has no realistic alternative but to do so.

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

Auditors’ Responsibilities for the Audit of the Consolidated Financial Statements

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

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

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

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

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

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

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

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

Table of Contents

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

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

From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of the consolidated financial statements as of and for the year ended December 31, 2018 and are therefore the key audit matters. We describe these matters in our auditors’ report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.

The engagement partner on the audit resulting in this independent auditors’ report is Sang Hyun Han.

Notes to the Consolidated Financial Statements

For the years ended December 31, 2018 and 2017

1. Basis of Preparation, Continued

(1) Basis of measurement

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

• derivative financial instruments measured at fair value;

• financial instruments measured at fair value through profit or loss;

• financial instruments measured at fair value through other comprehensive income;

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

(2) Functional and presentation currency

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

(3) Use of estimates and judgments

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

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

1) Critical judgments

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

2) Assumptions and estimation uncertainties

Information about assumptions and estimation uncertainties that have a significant risk of resulting in a material adjustment within the next financial year are included in the following notes: loss allowance (notes 7 and 37), estimated useful lives of costs to obtain a contract (notes 3 (1) and 8), property and equipment and intangible assets (notes 4 (8), (10), 14 and 16), impairment of goodwill (notes 4 (13) and 15), recognition of provision (notes 4 (18) and 19), measurement of defined benefit liabilities (notes 4 (17) and 21), and recognition of deferred tax assets (liabilities) (notes 4 (26) and 19).

(3) Use of estimates and judgments, Continued

3) Fair value measurement, Continued

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

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

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

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

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

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

If the inputs used to measure the fair value of an asset or a liability fall into different levels of the fair value hierarchy, then the fair value measurement is categorized in its entirety in the same level of the fair value hierarchy as the lowest level input that is significant to the entire measurement.

The Group recognizes transfers between levels of the fair value hierarchy at the end of the reporting period during which the change has occurred.

Information about assumptions used for fair value measurements are included in Note 37.

1. Changes in accounting policies

The significant accounting policies applied by the Group in these consolidated financial statements are the same as those applied by the Group in its consolidated financial statements as of and for the year ended December 31, 2017, except for the changes in accounting policies described below.

(1) K-IFRS No. 1115, Revenue from Contracts with Customers

K-IFRS No. 1115, Revenue from Contracts with Customers , establishes a comprehensive framework for determining whether, how much and when revenue is recognized. K-IFRS No. 1115 replaced the revenue recognition guidance, including K-IFRS No. 1018, Revenue , K-IFRS No. 1011, Construction Contracts , K-IFRS No. 2031, Revenue: Barter Transactions Involving Advertising Services , K-IFRS No. 2113, Customer Loyalty Programs , K-IFRS No. 2115, Agreements for the Construction of Real Estate, and K-IFRS No. 2118, Transfers of Assets from Customers .

For the years ended December 31, 2018 and 2017

1. Changes in accounting policies, Continued

(1) K-IFRS No. 1115, Revenue from Contracts with Customers , Continued

The Group has initially applied K-IFRS No. 1115 from January 1, 2018 using the cumulative effect method with the effect of initially applying this standard as an adjustment to the opening balance of retained earnings as at January 1, 2018. The Group applied K-IFRS No. 1115 only to contracts that were not completed at the date of initial application, which is January 1, 2018, using the practical expedient permitted by K-IFRS No.1115.

1) Identification of performance obligations in the contract

A substantial portion of the Group’s revenue is generated from providing wireless telecommunications services. K-IFRS No. 1115 requires the Group to evaluate goods or services promised to customers to determine if there are performance obligations other than wireless telecommunications service that should be accounted for separately. In the case of providing a wireless telecommunications service and selling a handset together to one customer, the Group allocates considerations from the customer between handset sales revenue and wireless telecommunications service revenue. The handset sales revenue is recognized when handset is delivered and the wireless telecommunications service revenue is recognized as revenue over the period of the contract term as stated in the subscription contract.

The Group also determined that pursuant to K-IFRS No. 1115, the installation service provided with the fixed-line telecommunication services is not distinct from the related fixed-line telecommunication services such as high speed broadband Internet or Internet Protocol TV (IPTV) services. Therefore, the Group concluded that the installation service and related fixed-line telecommunication service together represents one performance obligation. Therefore, installation fee is recognized as revenue over the contract term in which the Group has to provide fixed-line telecommunication services. The Group recognized W 23,063 million as contract liability on the consolidated statement of financial position as of January 1, 2018 due to such change in the accounting policies.

2) Allocation of the transaction price to each performance obligations

In accordance with K-IFRS No. 1115, the Group allocates the transaction price of a contract to each performance obligation on a relative stand-alone selling price basis. The Group uses “adjusted market assessment approach” method for estimating the stand-alone selling price of a good or service. However, in some circumstances, the Group uses ‘expected cost plus a margin’ approach.

In the case of providing a wireless telecommunications service and selling a handset together to one customer, the Group allocates the transaction price based on relative stand-alone selling prices. As a result of applying K-IFRS No. 1115, the Group recognized W 112,690 million and W 30,363 million of considerations allocated to handset sales revenue as contract assets and long-term contract assets, respectively, at January 1, 2018.

3) Incremental costs to acquire 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 historically were expensed as incurred and recognized as operating expenses. These commissions would not have been paid if there have been no binding contracts with subscribers. K-IFRS No. 1115 requires the Group to capitalize certain costs associated with commissions paid to obtain new customer contracts and amortize them over the expected contract periods with customers that were calculated based on the Group’s historical subscriber churn rate. As a result of applying K-IFRS No. 1115, the Group recognized W 1,695,704 and W 693,393 million of prepaid expenses and long-term prepaid expenses respectively as at the date of initial application, January 1, 2018.

4) Presentation of contract liability

Under K-IFRS No. 1115, the Group reclassified the receipts in advance and unearned revenue amounting to W 109,555 million that are related to prepaid rate plans and customer loyalty program to contract liabilities as at the date of initial application, January 1, 2018.

5) Impact of adopting K-IFRS No. 1115 on the consolidated financial statements

If the previous standards were applied to the Group’s consolidated statement of financial position as of December 31, 2018, prepaid expenses and long-term prepaid expenses would have been decreased by W 1,577,992 million and W 799,607 million, respectively, and contract assets and long-term contract assets would have been decreased by W 90,072 million and W 43,821 million. As a result, total assets would have been decreased by W 2,503,025 million with W 8,467 million increase in deferred tax assets. In addition, contract liabilities, long-term contract liabilities and deferred tax liabilities would have been decreased by W 140,711 million, W 43,102 million and W 664,240 million, respectively, while other liabilities such as receipts in advance and unearned revenue would have been increased by W 156,880 million. As a result, total liabilities would have been decreased by W 691,173 million. In relation to these changes in assets and liabilities, retained earnings and capital surplus and others would have been decreased by W 1,811,780 million, W 4,596 million respectively. Non-controlling interests would have been increased by W 4,524 million.

If the previous standards were applied to the Group’s consolidated statement of income for year ended December 31, 2018, revenues, advertising expenses and commission expenses would have been increased by W 85,801 million, W 51,204 million and W 12,714 million respectively, for which the total operating expenses would have been increased by W 66,137 million resulting in operating profit and profit before income tax to be increased by W 19,664 million. As a result, profit for the year would have been increased by W 88,197 million with decrease in income tax expense of W 68,533 million.

The adoption of K-IFRS No. 1115 did not have a material impact on the Group’s consolidated statement of cash flows for the year ended December 31, 2018.

K-IFRS No. 1109 sets out requirements for recognizing and measuring financial assets, financial liabilities and some contracts to buy or sell non-financial items. This standard replaces K-IFRS No. 1039, Financial Instruments: Recognition and Measurement . The Group adopted K-IFRS No. 1109, Financial Instruments , from January 1, 2018, and the Group has taken an exemption not to restate the consolidated financial statements for prior years with respects to transition requirements.

(2) K-IFRS No. 1109, Financial Instruments, Continued

1) Classification of financial assets and financial liabilities

K-IFRS No. 1109 largely retains the existing requirements in K-IFRS No. 1039 for the classification and measurement of financial liabilities. However, it eliminates the previous K-IFRS No. 1039 categories for financial assets of held-to-maturity, available-for-sale, and loans and receivables.

Under K-IFRS No. 1109, on initial recognition, a financial asset is classified as measured at: amortized cost; FVOCI-debt investment; FVOCI-equity investment; or FVTPL. The classification of financial assets under K-IFRS No. 1109 is generally based on the business model in which a financial asset is managed and its contractual cash flow characteristics. If a contract contains embedded derivatives and the host is an asset within the scope of K-IFRS No. 1109, then such embedded derivatives are not separated.

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 flow; 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 basis.

All financial assets not classified as measured at amortized cost or FVOCI as described above are measured at FVTPL. These include 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 FVOCI as at FVTPL if doing so eliminates or significantly reduces an accounting mismatch that would otherwise arise.

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

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.

In addition, as derivatives embedded in contracts where the host is a financial asset in the scope of K-IFRS No. 1109 are never separated, the available-for-sale financial assets related to the redeemable convertible preferred shares of W 15,342 million and the related derivative financial assets of W 222,257 million were reclassified to financial assets measured at FVTPL which were not designated as financial assets measured at amortized cost as the contractual terms of these assets do not give rise to cash flows that are solely payments of principal and interest on the principal amount outstanding on specified dates. As a result of this reclassification, as at January 1, 2018, accumulated OCI of W 5,336 million was reclassified to retained earnings, and due to its reclassification to financial assets measured at FVTPL, retained earnings was decreased by W 4,389 million in relation to fair value measurement. In addition, change in the fair value of these financial assets of W 1,984 million was recognized in profit before income tax during the year ended December 31, 2018.

(*2) As of January 1, 2018, available-for-sale financial assets such as marketable equity instruments amounting to W 713,613 million were reclassified to equity investments at FVOCI and debt instrument at FVOCI of W 713,399 million and W 214 million, respectively. As a result of this reclassification, as at January 1, 2018, retained earnings of W (-)90,322 million was reclassified to accumulated OCI and accumulated OCI was increased by W 5,441 million due to the fair value measurement of financial assets which were stated at cost under K-IFRS No. 1039. The Group designated equity instruments that are not held for trading as FVOCI on initial application of K-IFRS No. 1109 with no subsequent recycling of amounts from OCI to profit and loss.

(*3) As of January 1, 2018, accounts receivable – other of W 1,074,063 million were reclassified to financial assets at FVTPL. Upon the initial application of K-IFRS No. 1109, the Group reclassified the debt instruments to financial assets at FVTPL whose objectives of the business model are not achieved both by collecting contractual cash flows and selling financial assets. There was no material impact on retained earnings as at January 1, 2018 as the fair values of these debt instruments were not significantly different from the carrying amounts as of December 31, 2017.

(2) K-IFRS No. 1109, Financial Instruments, Continued

2) Impairment of financial assets

K-IFRS No. 1109 sets out the ‘expected credit loss’ (ECL) impairment model which replaces the ‘incurred loss’ model under K-IFRS No. 1039 for recognizing and measuring impairment. The new impairment model applies to financial assets measured at amortized cost, contract assets and debt investments at FVOCI, but not to investments in equity instruments. Under K-IFRS No. 1109, credit losses are recognized earlier than under K-IFRS No. 1039.

ECL is a probability-weighted estimate of credit losses. Credit losses are measured as the present value of all expected 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 carried at amortized cost and debt securities 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.

3) Hedge accounting

Upon initial application of K-IFRS No. 1109, the Group elected to apply hedge accounting requirements under K-IFRS No. 1109. The Group designates derivatives such as currency swaps as hedging instruments to hedge the risk of variability in cash flows associated with the foreign currency debentures and borrowings. As the Group’s hedging instruments as of January 1, 2018 satisfy the hedge requirements of retrospective testing (80~125%) under K-IFRS No. 1039, there is no material effect of applying K-IFRS No. 1109.

Notes to the Consolidated Financial Statements

For the years ended December 31, 2018 and 2017

1. Significant Accounting Policies

The significant accounting policies applied by the Group in the preparation of its consolidated financial statements in accordance with K-IFRSs are included below. The significant accounting policies applied by the Group in these consolidated financial statements are the same as those applied by the Group in its consolidated financial statements as of and for the year ended December 31, 2017, except for the changes in accounting policies described in Note 3.

(1) Operating segments

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

(2) Basis of consolidation

1) Business combination

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

Consideration transferred is generally measured at fair value, 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 K-IFRS No. 1032 and 1109.

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

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

2) Non-controlling interests

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

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

(2) Basis of consolidation, Continued

3) Subsidiaries

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

4) Loss of control

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

5) Interest in investees accounted for using the equity method

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

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

6) Intra-group transactions

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

7) Business combinations under common control

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

(3) Cash and cash equivalents

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

(4) Inventories

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

(5) Financial assets – Policies applicable from January 1, 2018

1) Classification

The Group classifies its financial assets into one of the following categories:

• financial assets at fair value through profit or loss (“FVTPL”)

• financial assets at fair value through other comprehensive income (“FVOCI”), and

• financial assets measured at amortized cost

Financial assets are classified based on the business model in which a financial asset is managed and its contractual cash flow characteristics. The Group reclassifies a debt instrument when, and only when, the business model for managing the financial asset is changed.

2) Measurement

A financial asset is initially measured at fair value plus, for an item not at FVTPL, transaction costs that are directly attributable to the acquisition. Transaction costs for a financial asset at FVTPL are recognized in profit or loss.

A hybrid financial instrument with embedded derivatives in the contract is considered as a whole when assessing whether contractual cash flows are solely payments of principal and interest.

2) Measurement, Continued

(i) Debt investments

A financial asset is subsequently measured based on its contractual cash flow characteristics and the business model in which a financial asset is managed. The Group classifies debt investments into one of the following categories:

① Financial assets at amortized cost

A financial asset is measured at amortized cost if it is held within a business model whose objective is to collect contractual cash flows, and the contractual cash flows are solely payments of principal and interest. A gain or loss on a financial asset that is measured at amortized cost and is not part of a hedging relationship is recognized in profit or loss when the financial asset is derecognized or impaired. Interest calculated using the effective interest method is included in finance income.

② Financial assets measured at fair value through other comprehensive income (“FVOCI”)

A financial asset is classified as FVOCI when it is held within a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets, and the contractual cash flows are solely payments of principal and interest. Changes in fair value other than impairment losses and reversal of impairment losses, interest income and foreign exchange gains and losses are recognized in other comprehensive income. The amounts accumulated in other comprehensive income are recycled to profit or loss when the financial assets is derecognized. Interest income calculated using the effective interest method is included in finance income. Foreign exchange gains and losses are presented as finance income or finance costs, impairment losses are presented as other expenses.

③ Financial assets at fair value through profit or loss (“FVTPL”)

Debt investments that are not classified at amortized cost or FVOCI are classified as FVTPL. A gain or loss on debt investments that are not part of a hedging relationship is recognized in profit or loss and is presented in finance income or costs in the statement of income for the period.

(ii) Equity investments

The Group subsequently measures all of its equity investments at fair value. The Group elected to recognize the changes in fair value of the equity investments that are held for long-term or strategic purposes in other comprehensive income. The amounts accumulated in other comprehensive income are not reclassified into profit or loss upon derecognition. Dividends from these equity investments are recognized as finance income when the right to receive the dividends is established.

Changes in the value of equity investments measured at FVTPL are presented in finance income or costs in the statement of income for the period.

(5) Financial assets – Policies applicable from January 1, 2018, Continued

3) Impairment

The Group estimates the expected credit losses (ECL) for the debt instruments that are measured at amortized cost and FVOCI based on the forward-looking data. The impairment approach is decided based on the assessment of significant increase in credit risk. However, the Group applies a practical expedient and recognizes impairment losses equal to lifetime ECLs for Accounts receivables – trade and lease receivables from the initial recognition.

4) Recognition and derecognition

A regular way purchase or sale of financial assets is recognized and derecognized using trade date accounting. A financial asset is derecognized when the contractual rights to the cash flows from the financial asset expire or when the Group transfers substantially all the risks and rewards of ownership of the financial asset.

If the Group retains substantially all the risks and rewards of ownership of a transferred asset due to a non-recourse features or others, the Group continues to recognize the transferred asset in its entirety and recognizes a financial liability for the consideration received.

5) Offsetting

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

(6) Financial assets – Policies applied before January 1, 2018

The Group recognizes and measures non-derivative financial assets by the following four categories: financial assets at fair value through profit or loss, held-to-maturity investments, loans and receivables and available-for-sale financial assets. The Group recognizes financial assets in the consolidated statement of financial position when the Group becomes a party to the contractual provisions of the instrument.

Upon initial recognition, non-derivative financial assets not at fair value through profit or loss are measured at their fair value plus transaction costs that are directly attributable to the acquisition of asset.

1) Financial assets at fair value through profit or loss

A financial asset is classified as financial asset at fair value through profit or loss if it is held for trading or is designated as such upon initial recognition. Upon initial recognition, transaction costs are recognized in profit or loss when incurred. Financial assets at fair value through profit or loss are measured at fair value, and changes therein are recognized in profit or loss.

2) Held-to-maturity investments

A non-derivative financial asset with a fixed or determinable payment and fixed maturity, for which the Group has the positive intention and ability to hold to maturity, is classified as held-to-maturity investment. Subsequent to initial recognition, held-to-maturity investments are measured at amortized cost using the effective interest rate method.

3) Loans and receivables

Loans and receivables are financial assets with fixed or determinable payments that are not quoted in an active market. Subsequent to initial recognition, loans and receivables are measured at amortized cost using the effective interest method except for loans and receivables of which the effect of discounting is immaterial.

4) Available-for-sale financial assets

Available-for-sale financial assets are those non-derivative financial assets that are designated as available-for-sale or are not classified as financial assets at fair value through profit or loss, held-to-maturity investments or loans and receivables. Subsequent to initial recognition, they are measured at fair value, with changes in fair value, net of any tax effect, recorded in other comprehensive income (OCI) in equity. Investments in equity instruments that do not have a quoted market price in an active market and whose fair value cannot be reliably measured are measured at cost.

5) Impairment of financial assets

A financial asset not carried at fair value through profit or loss is assessed at each reporting date to determine whether there is objective evidence that it is impaired. A financial asset 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 the asset that can be reliably estimated. However, losses expected as a result of future events, regardless of likelihood, are not recognized.

Objective evidence that a financial asset is impaired includes following loss events:

• significant financial difficulty of the issuer or obligor;

• a breach of contract, such as default or delinquency in interest or principal payments;

• the lender, for economic or legal reasons relating to the borrower’s financial difficulty, granting to the borrower a concession that the lender would not otherwise consider;

• it becoming probable that the borrower will enter bankruptcy or other financial reorganization;

• the disappearance of an active market for that financial asset because of financial difficulties; or

• observable data indicating that there is a measurable decrease in the estimated future cash flows from a group of financial assets since the initial recognition of those assets, although the decrease cannot yet be identified with the individual financial assets in the group.

In addition, for an investment in an equity security classified as available-for-sale financial asset, a significant or prolonged decline in its fair value below its cost is objective evidence of impairment.

If financial assets have objective evidence that they are impaired, impairment losses are measured and recognized.

(6) Financial assets – Policies applied before January 1, 2018, Continued

5) Impairment of financial assets, Continued

(i) Financial assets measured at amortized cost

An impairment loss in respect of a financial asset measured at amortized cost is calculated as the difference between its carrying amount and the present value of its estimated future cash flows discounted at the asset’s original effective interest rate. The Group can recognize impairment losses directly or by establishing an allowance account. If, in a subsequent period, the amount of the impairment loss decreases and the decrease can be objectively related to an event occurring after the impairment was recognized (such as an improvement in the debtor’s credit rating), the previously recognized impairment loss is reversed either directly or by adjusting an allowance account.

(ii) Financial assets carried at cost

If there is objective evidence that an impairment loss has occurred on an unquoted equity instrument that is not carried at fair value because its fair value cannot be reliably measured, or on a derivative asset that is linked to and must be settled by delivery of such an unquoted equity instrument, the amount of the impairment loss is measured as the difference between the carrying amount of the financial asset and the present value of estimated future cash flows discounted at the current market rate of return for a similar financial asset. Such impairment losses are not reversed.

(iii) Available-for-sale financial assets

When a decline in the fair value of an available-for-sale financial asset has been recognized in other comprehensive income and there is objective evidence that the asset is impaired, the cumulative loss that had been recognized in other comprehensive income is reclassified to profit or loss as a reclassification adjustment even though the financial asset has not been derecognized. Impairment losses recognized in profit or loss for an investment in an equity instrument classified as available-for-sale is not reversed through profit or loss subsequently. If, in a subsequent period, the fair value of a debt instrument classified as available-for-sale increases and the increase can be objectively related to an event occurring after the impairment loss was recognized in profit or loss, the impairment loss is reversed to the amount of amortized cost that would otherwise have been recognized as of the recovery date.

6) De-recognition of financial assets

The Group derecognizes a financial asset when the contractual rights to the cash flows from the asset expire or the Group transfers the rights to receive the cash flows on the financial asset in a transaction in which substantially all the risks and rewards of ownership of the financial asset are transferred. Any interest in transferred financial assets that is created or retained by the Group is recognized as a separate asset or liability. If the Group retains substantially all the risks and rewards of ownership of the transferred financial assets, the Group continues to recognize the transferred financial assets and recognizes financial liabilities for the consideration received.

7) Offsetting between financial assets and financial liabilities

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

(7) 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.

1) Hedge accounting

The Group holds forward exchange contracts, interest rate swaps, currency swaps and other derivative contracts to manage interest rate risk and foreign exchange risk. The Group designates derivatives as hedging instruments to hedge the foreign currency 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.

Cash flow hedge

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

2) Other derivative financial instruments

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

(8) Property and equipment

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

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

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

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

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

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
Other property and equipment	2 ~10

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

(9) 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 that period.

(10) Intangible assets

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

Amortization of intangible assets except for goodwill is calculated 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 are expected to be available for use as there are no foreseeable limits to the periods. These intangible assets including brand are determined as having indefinite useful lives and not amortized.

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

	Useful lives (years)
Frequency usage rights	5 ~ 13
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.

(10) Intangible assets, Continued

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.

(11) 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.

(12) Investment property

Property held for the purpose of earning rentals or benefiting from capital appreciation is classified as investment property. Investment property is initially measured at its cost. Transaction costs are included in the initial measurement. Subsequently, investment property is carried at depreciated cost less any accumulated impairment loss.

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

Investment properties, except for land, are depreciated on a straight-line basis over 15~40 years as estimated useful lives.

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.

(13) Impairment of non-financial assets

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

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

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

Goodwill acquired in a business combination is allocated to each CGU that is expected to benefit from the synergy arising from the business acquired. Any impairment identified at the CGU level will first reduce the carrying value 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.

(14) Leases

The Group classifies and accounts for leases as either a finance or operating lease, depending on the terms. Leases where 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.

1) Finance leases

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 charge and the reduction of the outstanding liability. The finance charge 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.

2) 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.

3) 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.

(15) Non-current assets held for sale

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

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

(16) Non-derivative financial liabilities

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

1) Financial liabilities at fair value through profit or loss

Financial liabilities at fair value through profit or loss include financial liabilities held for trading or designated as such upon initial recognition. Subsequent to initial recognition, these liabilities are measured at fair value, and changes therein are recognized in profit or loss. Upon initial recognition, transaction costs that are directly attributable to the issue of the financial liability are recognized in profit or loss as incurred.

2) Other financial liabilities

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

3) Derecognition of financial liability

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

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

(17) Employee benefits

1) Short-term employee benefits

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

2) Other long-term employee benefits

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

3) Retirement benefits: defined contribution plans

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

4) Retirement benefits: defined benefit plans

At of the end of reporting period, defined benefits 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, 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.

5) Termination benefits

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

(18) 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.

(19) Transactions in foreign currencies

1) 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 assets and liabilities denominated in foreign currencies that are measured at fair value are retranslated to the functional currency at the exchange rate at the date that the fair value was determined.

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

(19) Transactions in foreign currencies, Continued

2) Foreign operations

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

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

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

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

(20) 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 Group 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

(21) Hybrid bond

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

(22) Share-based Payment

For equity-settled share-based payment transaction, if the fair value of the goods or services received cannot be reliably estimated, the Group measures the value indirectly by reference to the fair value of the equity instruments granted. The related expense with a corresponding increase in capital surplus and others is recognized over the vesting period of the awards. The amount recognized as an expense is adjusted to reflect the number of awards for which the related service and non-market performance conditions are expected to be met, such that the amount ultimately recognized is based on the number of awards that meet the related service and non-market performance conditions at the vesting date.

(23) Revenue - Policies applicable from January 1, 2018

The Group has initially adopted K-IFRS No. 1115, Revenue from Contracts with Customers, from January 1, 2018. See note 3 (1) for additional information.

1) Identification of performance obligations in contracts with customers

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

2) Allocation of the transaction price to each performance obligation

In accordance with K-IFRS No. 1115, the Group allocates the transaction price of a contract to each performance obligation identified on a relative stand-alone selling price basis. The Group uses “adjusted market assessment approach” for estimating the stand-alone selling price of a good or service. As an exception, the Group uses “Expected cost plus a margin approach” for insignificant transactions.

3) 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 allocated to the loyalty program is deferred and is recognized as revenue when loyalty points are redeemed. The deferred revenue is included in contract liabilities.

(24) Revenue - Policies applied before January 1, 2018

Revenue from the sale of goods, rendering of services or use of assets is measured at the fair value of the consideration received or receivable. Returns, trade discounts and volume rebates are recognized as a reduction of revenue.

When two or more revenue generating activities or deliverables are sold under a single arrangement, each deliverable that is considered to be a separate unit of account is accounted for separately. The allocation of consideration from a revenue arrangement to its separate units of account is based on the relative fair values of each unit.

1) Services rendered

Revenue from cellular services consists of revenue from basic charges, voice charges, data charges, data-roaming services and interconnection charges. Such revenues are recognized as services are performed.

Revenue from fixed-line services includes domestic and long-distance call charges, international phone connection charges, installation service and broadband internet services. Such revenues are recognized as the related services are performed.

Revenue from other services rendered is recognized in profit or loss in proportion to the stage of completion of the transaction at the reporting date. The stage of completion is assessed by reference to surveys of work performed.

2) Goods sold

Revenue is recognized when persuasive evidence exists, usually in the form of an executed sales agreement, that the significant risks and rewards of ownership have been transferred to the buyer, recovery of the consideration is probable, the associated costs and possible return of goods can be estimated reliably, there is no continuing management involvement with the goods, and the amount of revenue can be measured reliably.

3) Commission revenue

In connection with the commission revenue from e-commerce services, the Group has determined that it is acting as an agent due to the followings:

• The Group does not bear inventory risk or have responsibility for the delivery goods;

• All of the credit risks are borne by suppliers of goods though the Group collects the proceeds from end customers on behalf of the suppliers; and

• The Group has no latitude in establishing prices regarding goods sold in e-commerce.

4) Customer loyalty programs

For customer loyalty programs, the fair value of the consideration received or receivable in respect of the initial sale is allocated between the award credits and the other components of the sale. The amount allocated to the award credits is estimated by reference to the fair value of the services to be provided with respect to the redeemable award credits. The fair value of the services to be provided with respect to the redeemable portion of the award credits granted to the customers in accordance with customer loyalty programs is estimated taking into account the expected redemption rate and timing of the expected redemption. Considerations allocated to the award credits are deferred and revenue is recognized when the award credits are recovered and the Group performs its obligation to provide the service. The amount of revenue recognized is based on the relative size of the total award credits that are expected to be redeemed and the redeemed award credits in exchange for services.

(25) 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 are recognized as it accrues in profit or loss using the effective interest rate method.

(26) Income taxes

Income tax expense comprises current and deferred tax. Current tax and deferred tax are recognized in profit or loss except for transactions or events directly recognized in other comprehensive income or equity.

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

1) Current tax

In accordance with the tax-consolidation system, the Parent Company calculates current taxes for the Parent Company and its wholly owned domestic subsidiaries and recognizes the income tax payable as current tax liabilities of the Parent Company.

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

2) Deferred tax

Deferred tax is recognized 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.

2) Deferred tax, Continued

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.

(27) 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.

(28) Standards issued but not yet effective

The following new standards are effective for annual periods beginning after January 1, 2018 and earlier application is permitted; however, the Group has not adopted the following new standards early in preparing the accompanying consolidated financial statements.

(28) Standards issued but not yet effective, Continued

K-IFRS No. 1116 Leases

K-IFRS No. 1116, published on May 22, 2017 is effective for annual periods beginning on or after January 1, 2019, with early adoption permitted. K-IFRS No. 1116, replaces existing leases guidance including K-IFRS No. 1017, Leases , K-IFRS No. 2104, Determining whether an Arrangement contains a Lease , K-IFRS No.2015, Operating Leases - Incentives and K-IFRS No. 2027, Evaluating the Substance of Transactions Involving the Legal Form of a Lease.

The Group will assess at inception of a contract whether that contract is, or contains, a lease. 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. However, the Group can apply a practical expedient to grandfather their previous assessment of whether existing contracts are, or contain, leases.

A lessee recognizes a right-of-use asset representing its right to use the underlying assets and a lease liability representing its obligation to make lease payments. There are recognition exemptions for short-term leases (lease term ends within 12 months at the commencement date of the lease) or leases of low-value items (assets with a value of KRW 6 million or less). As a practical expedient, a lessee can elect, by class of underlying asset, not to separate lease components from any associated non-lease components. A lessee that takes this election accounts for the lease component and the associated non-lease components as a single lease component.

A lessor’s accounting remains similar to current requirements, K-IFRS No. 1017 Leases .

1) A lessee’s accounting - application and financial impacts

A lessee is permitted to adopt the standard retrospectively according to K-IFRS No. 1008, Accounting Policies, Changes in Accounting Estimates and Errors, (‘Full retrospective approach’) or to follow a modified retrospective approach in which the lessee recognizes the cumulative effect of initial application of the standard as an adjustment to equity at the date of initial application. (‘Modified retrospective approach’)

The Group plans to apply K-IFRS No.1116 initially on January 1, 2019 by using the modified retrospective approach. Therefore, the cumulative effect of adopting K-IFRS No.1116 will be recognized as an adjustment to the opening balance of retained earnings at January 1, 2019 with no restatement of comparative information.

The Group is assessing the financial impact of the adoption of K-IFRS No. 1116 on its consolidated financial statements. It is impractical to provide a reasonable estimate of the financial impact until the Group completes this analysis.

The Group plans to account for the lease component and the associated non-lease components as a single lease component applying the practical expedient. In addition, the Group plans to account for leases for which the lease term ends within 12 months of the date of initial application as short-term leases.

According to the Group’s preliminary analysis of application of the K-IFRS 1116, right-of-use assets and lease liabilities are expected to increase as of January 1, 2019. Based on the preliminary assessment, the Group expects lease expenses to decrease and depreciation expenses of the right-of-use assets and interest expenses of lease liabilities to increase.

(*) Segment information for the year ended December 31, 2017 was restated as Eleven Street Co., Ltd. was spun off from SK Planet Co., Ltd., and newly established during the year ended December 31, 2018, and is only included in the E-Commerce Services segment.

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

No single customer contributed 10% or more to the Group’s total revenue for the years ended December 31, 2018 and 2017.

(3) The Group applies the practical expedient that allows the Group to estimate the loss allowance for accounts receivables - 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, 2018 are as follows:

(In millions of won)		Less than 6 months	6 months ~ 1 year	1 year ~ 3 years	More than 3 years
Telecommunications service revenue	Expected credit loss rate	W	2.70 %	58.20 %	74.10 %	86.36 %
	Gross amount		1,135,441	48,796	125,181	31,547
	Loss allowance		30,628	28,401	92,753	27,244
Other revenue	Expected credit loss rate		1.18 %	35.47 %	40.03 %	68.44 %
	Gross amount		817,201	9,126	31,345	81,453
	Loss allowance		9,603	3,237	12,546	55,745

As the Group is a wireless and fixed-line telecommunications service provider, the Group’s financial assets measured at amortized cost consist primarily 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 was 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. Prepaid expenses

As discussed in note 3, the Group adopted K-IFRS No. 1115, Revenue from Contracts with Customers, during the year beginning January 1, 2018.

The Group capitalized certain costs associated with commissions paid to retail stores and authorized dealers to obtain new and retained customer contracts as prepaid expenses, which the Group previously expensed. These prepaid expenses are amortized on a straight-line basis over the periods that the Group expects to maintain its customers based on the Group’s historical subscriber churn rate.

(1) Details of prepaid expenses as of December 31, 2018 and 2017 are as follows:

Other goodwill		118,847	250,338
	W	2,938,563	1,915,017

(2) Details of the impairment testing of Goodwill as of December 31, 2018 is as follows:

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

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

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

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

• other goodwill: e-commerce, Security services, and other.

(*1) Goodwill related to acquisition 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 6.1% (6.6% in prior year) to the estimated future cash flows based on financial budgets for the next five years. An annual growth rate of (-)0.4% was applied for the cash flows expected to be incurred after five years and is not expected to exceed the Group’s long-term wireless telecommunication business 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 6.2% (5.1% in prior year) to the estimated future cash flows based on financial budgets for the next five years. An annual growth rate of 1.0% was applied for the cash flows expected to be incurred after five years and is not expected to exceed the Group’s long-term wireless telecommunication business 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) Details of the changes in goodwill for the years ended December 31, 2018 and 2017 are as follows:

(In millions of won)
	2018		2017
Beginning balance	W	1,915,017		1,932,452

Other		(15,511	)	(19,215	)
	W 2,938,563		1,915,017

(*1) The Group classified shopkick, Inc. as a single CGU and determined the recoverable amount based on fair value less cost of disposal which is estimated based on a third party’s asking price. This fair value is classified as level 3 in the fair value hierarchy based on the inputs used in the valuation techniques. The Group recognized W 153,367 million and W 52,373 million of impairment losses for goodwill and intangible assets, respectively.

(*2) Digital contents service related goodwill of IRIVER LIMITED

The recoverable amount of the CGU was measured based on the value estimated on the present value of the future cash flows for the next five years discounted by 14.4% per annum. The cash flows expected to occur in the period exceeding five years were assumed to increase by 0.0% based on the characteristics of the business unit and of the industry it belongs to. As a result of the impairment test, the carrying value of the CGU exceeds the recoverable amount, thus the Group recognized W 13,471 million of impairment loss.

As of December 31, 2018 and 2017, accumulated impairment losses are W 217,548 million and W 50,710 million, respectively.

1. 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 and accounts receivable - trade and other. Financial liabilities consist of accounts payable - trade and other, borrowings, and debentures.

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, JPY and EUR. 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.

Assets			Liabilities
Foreign currencies		Won equivalent	Foreign currencies		Won equivalent
USD	173,560	W	194,058	1,588,522	W	1,776,126

Others	—		3,484	—		18
		W	224,431		W	1,779,433

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, 2018, a hypothetical change in exchange rates by 10% would have increase (reduce) the Group’s income before income tax as follows:

(In millions of won)	If increased by 10%	If decreased by 10%
USD	W	12,593	(12,593	)
EUR		1,856	(1,856	)
JPY		504	(504	)
Others		347	(347	)
	W	15,300	(15,300	)

(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.

Accordingly, 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, 2018, the floating-rate borrowings and bonds of the Group are W 239,000 million and W 335,430 million, respectively, and the Group has entered into interest rate swap agreements, as described in note 22, for 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 for the next year would change by W 1,400 million in relation to floating-rate borrowings that are exposed to interest rate risk.

2) Credit risk

The maximum credit exposure as of December 31, 2018 and 2017 are as follows:

(In millions of won)	December 31, 2018	December 31, 2017

Derivative financial assets		55,457	30,956
	W	6,262,329	6,227,140

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) Account receivable – trade and contract assets

The Group establishes a loss allowance in respect of account 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, 2018 are included in note 7.

(ii) Debt investments

The credit risk arises from debt investments included in W 1,046,897 million of financial instruments, W 11,672 million of investment securities and W 1,621,938 million of loans and other receivables. To limit the exposure to this risk, the Group transacts only with financial institutions with credit ratings that are considered to be low credit risk.

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

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

The Group’s maximum exposure to credit risk is equal to each financial asset’s carrying amount. The gross carrying amounts of each financial asset except for the accounts receivable – trade and derivative financial assets as of December 31, 2018 are as follows.

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

Impairment on cash and cash equivalents has been measured on a 12-month expected loss basis and reflects the short maturities of the exposures. The Group considered that its cash and cash equivalents have low credit risk based on the credit ratings of the counterparties assigned by external credit rating agencies.

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

Available-for-sale financial assets amounting to W 199,903 million as of December 31, 2017 is measured at cost in accordance with K-IFRS No. 1039 since they are equity instruments which do not have quoted price in an active market for the identical instruments and for which fair value cannot be reliably measured using other valuation methods.

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.
