Managements Responsibility for the Separate Financial Statements

Management is responsible for the preparation and fair presentation of these separate financial statements in accordance with Korean International Financial Reporting Standards, and for such internal control as management determines is necessary to enable the preparation of separate financial statements that are free from material misstatement, whether due to fraud or error.

Auditors Responsibility

Our responsibility is to express an opinion on these separate financial statements based on our audits. We conducted our audits in accordance with Korean Standards on Auditing. Those standards require that we comply with ethical requirements and plan and perform the audit to obtain reasonable assurance about whether the separate financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the separate financial statements. The procedures selected depend on our judgment, including the assessment of the risks of material misstatement of the separate financial statements, whether due to fraud or error. In making those risk assessments, we consider internal control relevant to the entitys preparation and fair presentation of the separate financial statements 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 entitys internal control. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of accounting estimates made by management, as well as evaluating the overall presentation of the separate financial statements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the separate financial statements present fairly, in all material respects, the separate financial position of the Company as at December 31, 2016 and 2015 and of its separate financial performance and its separate cash flows for the years then ended in accordance with Korean International Financial Reporting Standards.

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

derivative financial instruments measured at fair value;

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

available-for-sale financial assets measured at fair value; and

These separate financial statements are presented in Korean won, which is the currency of the primary economic environment in which the Company operates.

Basis of Presentation, Continued

(4) Use of estimates and judgments, Continued

3) Fair value measurement

A number of the Companys accounting policies and disclosures require the measurement of fair values, for both financial and non-financial assets and liabilities. The Company has an established policies and processes with respect to the measurement of fair values. This includes a valuation team that has overall responsibility for overseeing all significant fair value measurements, including Level 3 fair values, and reports directly to the finance executives.

The valuation team regularly reviews significant unobservable inputs and valuation adjustments. If third party information, such as broker quotes or pricing services, are used to measure fair values, then the valuation team 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 Company 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 Company 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 29.

The Company applies the cost method to investments in subsidiaries and associates in accordance with K-IFRS No. 1027. Dividends from a subsidiary or associate are recognized in profit or loss when the right to receive the dividend is established.

(3) Business combinations under common control

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

(4) Cash and cash equivalents

Cash and cash equivalents comprise cash balances, call deposits and financial asset 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.

(5) 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.

(6) Non-derivative financial assets

The Company 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 Company recognizes financial assets in the separate statement of financial position when the Company 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.

(i) 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.

(ii) Held-to-maturity investments

A non-derivative financial asset with a fixed or determinable payment and fixed maturity, for which the Company has the positive intention and ability to hold to maturity, are 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.

(6) Non-derivative financial assets, Continued

(iii) 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.

(iv) 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.

(v) De-recognition of financial assets

The Company derecognizes a financial asset when the contractual rights to the cash flows from the asset expire, or it transfers the rights to receive the contractual 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 Company is recognized as a separate asset or liability. If the Company retains substantially all the risks and rewards of ownership of the transferred financial assets, the Company continues to recognize the transferred financial assets and recognizes financial liabilities for the consideration received.

(vi) Offsetting between financial assets and financial liabilities

Financial assets and liabilities are offset and the net amount is presented in the statement of financial position only when the Company currently has a legally enforceable right to offset the recognized amounts, and there is the intention 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, and changes therein are accounted for as described below.

(i) Hedge accounting

The Company holds forward exchange contracts, interest rate swaps, currency swaps and other derivative contracts to manage interest rate risk and foreign exchange risk. The Company designates derivatives as hedging instruments to hedge the risk of changes in the fair value of assets, liabilities or firm commitments (a fair value hedge) and foreign currency risk of highly probable forecasted transactions or firm commitments (a cash flow hedge).

Table of Contents

(7) Derivative financial instruments, including hedge accounting, Continued

(i) Hedge accounting, Continued

On initial designation of the hedge, the Company 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.

Fair value hedge

Changes in the fair value of a derivative hedging instrument designated as a fair value hedge are recognized in profit or loss. The gain or loss from remeasuring the hedging instrument at fair value for a derivative hedging instrument and the gain or loss on the hedged item attributable to the hedged risk are recognized in profit or loss in the same line item of the statement of income. The Company discontinues fair value hedge accounting if the hedging instrument expires or is sold, terminated or exercised, or if the hedge no longer meets the criteria for hedge accounting. Any adjustment arising from gain or loss on the hedged item attributable to the hedged risk is amortized to profit or loss from the date the hedge accounting is discontinued.

Cash flow hedge

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

(ii) Separable embedded derivatives

Embedded derivatives are separated from the host contract and accounted for separately only if the following criteria have been met:

(a) the economic characteristics and risks of the embedded derivative are not closely related to those of the host contract;

(b) a separate instrument with the same terms as the embedded derivative would meet the definition of a derivative; and

(c) the hybrid (combined) instrument is not measured at fair value with changes in fair value recognized in profit or loss.

Changes in the fair value of separable embedded derivatives are recognized immediately in profit or loss.

(7) Derivative financial instruments, including hedge accounting, Continued

(iii) Other derivative financial instruments

Changes in the fair value of other derivative financial instrument not designated as a hedging instrument are recognized immediately in profit or loss.

(8) 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 that asset that can be estimated reliably. 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 borrowers 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, 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.

(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 assets original effective interest rate. The Company 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 related objectively to an event occurring after the impairment was recognized (such as an improvement in the debtors credit rating), the previously recognized impairment loss is reversed either directly or by adjusting an allowance account.

(8) Impairment of financial assets, Continued

(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 from equity 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, with the amount of the reversal recognized in profit or loss.

(9) 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.

Subsequent to initial recognition, an item of property and equipment is carried at its cost less any accumulated depreciation and any 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 Company and the cost of the item can be measured reliably. 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 assets 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.

Table of Contents

Significant Accounting Policies, Continued

(9) Property and equipment, Continued

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 Companys property and equipment are as follows:

	Useful lives (years)
Buildings and structures	15, 30
Machinery	3 ~ 6
Other property and equipment	4 ~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.

(10) Borrowing costs

The Company 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. Assets that are ready for their intended use or sale when acquired are not qualifying assets.

To the extent that the Company borrows funds specifically for the purpose of obtaining a qualifying asset, the Company 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 Company borrows funds generally and uses them for the purpose of obtaining a qualifying asset, the Company 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 Company 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 Company capitalizes during a period do not exceed the amount of borrowing costs incurred during that period.

Significant Accounting Policies, Continued

(11) 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. This intangible asset is determined as having indefinite useful lives and not amortized.

The estimated useful lives of the Companys intangible assets are as follows:

	Useful lives (years)
Frequency usage rights	5 ~ 13.1
Land usage rights	5
Industrial rights	5, 10
Development costs	5
Facility usage rights	10, 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 are accounted for as changes in accounting estimates.

Expenditures on research activities are recognized in profit or loss as incurred. Development expenditures are capitalized only if development costs can be measured reliably, the product or process is technically and commercially feasible, future economic benefits are probable, and the Company 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.

(12) Government grants

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

(i) Grants related to assets

Government grants whose primary condition is that the Company 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.

(ii) Grants related to income

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

(13) Impairment of non-financial assets

The carrying amounts of the Companys 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 assets 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 amount to their carrying amount.

The Company estimates the recoverable amount of an individual asset, if it is impossible to measure the individual recoverable amount of an asset, then the Company 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 synergies 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 assets 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 Company classifies and accounts for leases as either a finance or operating lease, depending on the terms. Leases where the Company assumes substantially all of the risks and rewards of ownership are classified as finance leases. All other leases are classified as operating leases.

(i) Finance leases

At the commencement of the lease term, the Company recognizes as finance assets and finance liabilities in its separate 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 Company adopts for depreciable assets that are owned. If there is no reasonable certainty that the Company 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 Company reviews to determine whether the leased assets are impaired at the reporting date.

(ii) 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 period of the lease.

(iii) 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 Company 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 Company concludes for a financial lease that it is impracticable to separate the payments reliably, the Company 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 Companys incremental borrowing rate of interest.

Significant Accounting Policies, Continued

(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 sale rather than through continuing use, are classified as held for sale. In order to be classified as held for sale, the asset (or disposal group) must be available for immediate sale in its present condition and its sale must be highly probable. The assets or disposal group that are classified as non-current assets held for sale are measured at the lower of their carrying amount and fair value less cost to sell. The Company recognizes an impairment loss for any initial or subsequent write-down of an asset (or disposal group) 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 Company 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 Company recognizes financial liabilities in the separate statement of financial position when the Company becomes a party to the contractual provisions of the financial liability.

(i) 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, financial liabilities at fair value through profit or loss 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.

(ii) 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 using the effective interest method.

The Company derecognizes a financial liability from the separate statement of financial position when it is extinguished (i.e. when the obligation specified in the contract is discharged, cancelled or expires).

(17) Employee benefits

(i) 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 the related service. When an employee has rendered service to the Company during an accounting period, the Company recognizes the undiscounted amount of short-term employee benefits expected to be paid in exchange for that service.

(ii) 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 the related service. The Companys 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.

(iii) Retirement benefits: defined contribution plans

When an employee has rendered service to the Company during a period, the Company 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 Company 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.

(iv) Retirement benefits: defined benefit plans

At 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 Company 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 Company 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 Company recognizes gain or loss on a settlement when the settlement of defined benefit plan occurs.

Table of Contents

Significant Accounting Policies, Continued

(17) Employee benefits, Continued

(v) Termination benefits

The Company recognizes a liability and expense for termination benefits at the earlier of the period when the Company can no longer withdraw the offer of those benefits and the period when the Company 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 Company 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. Where the effect of the time value of money is material, provisions are determined at the present value of the expected future cash flows.

Where 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

Transactions in foreign currencies are translated to the functional currency of the Company 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 reporting dates exchange rate. 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.

(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 Company repurchases its own shares, the amount of the consideration paid is recognized as a deduction from equity and classified as treasury shares. The profits 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 Company recognizes a financial instrument issued by the Company as an equity instrument if it does not include contractual obligation to deliver financial assets including cash to the counter party.

(22) Revenue

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.

(i) 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. Revenues received for the activation of service are deferred and recognized over the average customer retention period.

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.

(ii) 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.

(22) Revenue, Continued

(iii) Customer loyalty programmes

For customer loyalty programmes, 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 programmes 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 Company 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.

(23) Finance income and finance costs

Finance income comprises interest income on funds invested (including available-for-sale financial assets), dividend income, gains on disposal of available-for-sale financial assets, changes in fair value of financial assets at fair value through profit or loss, 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 on the date that the Companys right to receive payment is established.

Finance costs comprise interest expense on borrowings, unwinding of the discount on provisions, changes in fair value of financial assets at fair value through profit or loss, and losses on hedging instruments that are recognized in profit or loss. Interest expense on borrowings and debentures are recognized in profit or loss using the effective interest rate method.

(24) Income taxes

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

The Company prepares consolidated income tax returns under the tax-consolidation system and its economically unified wholly owned subsidiaries.

(i) Current tax

In accordance with the tax-consolidation system, the Company calculates current taxes on the consolidated taxable income for the Company and its wholly owned domestic subsidiaries and recognizes the income tax payable as current tax liabilities of the 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 any adjustment to tax payable in respect of previous years. 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.

Significant Accounting Policies, Continued

(24) Income taxes, Continued

(ii) 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 Company recognizes a deferred tax liability for all taxable temporary differences, except for the difference associated with investments in subsidiaries and associates that the Company is able to control the timing of the reversal of the temporary difference and it is probable that the temporary difference will not reverse in the foreseeable future. The Company 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.

The Company 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 Company 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 there is a legally enforceable right to offset the related current tax liabilities and assets, and they relate to income taxes levied by the same tax authority and they are intended to be settled 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.

(25) Earnings per share

The Company 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 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 convertible notes and share options granted to employees, if any.

(26) Standards issued but not yet effective

The following new standards are effective for annual periods beginning after January 1, 2016 and earlier application is permitted; however, the Company has not early adopted the following new standards in preparing these financial statements.

1) K-IFRS No. 1109, Financial Instruments

K-IFRS No. 1109, published on September 25, 2015 which will replace the K-IFRS No. 1039 Financial Instruments: Recognition and Measurement , is effective for annual periods beginning on or after January 1, 2018, with early adoption permitted. The Company currently plans to apply K-IFRS No.1109 in the period beginning on January 1, 2018.

Adoption of K-IFRS No. 1109 will generally be applied retrospectively, except for the following:

exemption allowing the Company not to restate comparative information for prior periods with respect to classification and measurement (including impairment) changes; and

Prospective application of new hedge accounting except for those specified in K-IFRS 1109 for retrospective application such as accounting for the time value of options and the forward element of forward contracts.

Key features of K-IFRS No. 1109 includes new classification and measurement approach for financial assets that reflects the business model in which assets are managed and their cash flow characteristics, impairment model based on changes in expected credit losses, and new approach to hedge qualification and methods for assessing hedge effectiveness.

To ensure smooth implementation of K-IFRS No.1109, the Company needs to assess the financial impact of adopting K-IFRS No. 1109, to formulate the accounting policy, and to design, implement and enhance the accounting system and related controls. The expected quantitative impact of adopting K-IFRS No. 1109 on the Companys financial statements cannot be reliably estimated because it will be dependent on the financial instruments that the Company holds and economic conditions at that time as well as accounting elections and judgments that it will make in the future.

The Company plans to change the accounting process and internal control and to assess the financial impact on its financial statements resulting from the adoption of K-IFRS No. 1109 by December 31, 2017. Qualitative impacts on its financial statements upon adoption of K-IFRS No. 1109 are as follows:

i) Classification and measurement of financial assets

Classification of for financial assets under K-IFRS No. 1109 is driven by the entitys business model for managing financial assets and their contractual cash flows. This contains three principal classification categories: financial assets measured at amortized cost, fair value through other comprehensive income (FVOCI) and fair value through profit or loss (FVTPL). Derivatives embedded in contracts where the host is a financial asset are never bifurcated. Instead, the hybrid financial instrument as a whole is assessed for classification. Details of the classification based on business models and contractual cash flows are as follows;

| Business model assessment | Contractual cash flow
characteristics — Solely payments of principal and interest | Others |
| --- | --- | --- |
| Hold to collect contractual cash flows | Amortized cost(1) | FVTPL-measured at fair value (2) |
| Hold to collect contractual cash flows and sell financial assets | FVOCI- measured at fair value (*1) | |
| Hold to sell financial assets and others | FVTPL-measured at fair value | |

(*1) To eliminate or significantly reduce the accounting mismatch, the Company may irrevocably designate a financial asset as measured at FVTPL using the fair value option at initial recognition.

(*2) Equity instruments that are not held for trading may be irrevocably designated as FVOCI using the fair value option.

As new classification requirements for financial assets under K-IFRS No. 1109 are more stringent than requirements under K-IFRS No. 1039, the adoption of the new standard may result in increase in financial assets designated as FVTPL and higher volatility in profit or loss of the Company. As of December 31, 2016, the Companys financial assets consist of W 3,722,715 million of loans and receivables, W 650,947 million of available-for-sale financial assets, and W 14,727 million of financial assets at fair value through profit or loss.

A financial asset is measured at amortized cost under K-IFRS No. 1109 if the asset is held by the Company to collect its contractual cash flows and the assets contractual cash flows represent solely payments of principal and interest. As of December 31, 2016, the Company has W 3,722,715 million of loans and receivables measured at amortized cost.

A financial asset is measured at FVOCI under K-IFRS No. 1109 if the objective of the business model is achieved both by collecting contractual cash flows and selling financial assets; and the assets contractual cash flows represent solely payments of principal and interest. As of December 31, 2016, the Company has W 2,930 million of debt instruments classified as available-for-sale financial assets.

1) K-IFRS 1109, Financial Instruments , Continued

i) Classification and measurement of financial assets, Continued

Under K-IFRS No. 1109, equity instruments that are not held for trading may be irrevocably designated as FVOCI on initial recognition with no recycling of amounts from OCI to profit and loss. As of December 31, 2016, the Company has W 648,017 million of available-for-sale equity instruments; and unrealized valuation gain from available-for-sale equity instruments amounting to W 41,271 million is recycled from OCI to profit or loss during the year ended December 31, 2016.

All other financial assets are measured at FVTPL. As of December 31, 2016, the Company has W 7,359 million of debt instrument designated as FVTPL using the fair value option.

ii) Classification and measurement of financial liabilities

Under K-IFRS No. 1109, for the financial liabilities designated as FVTPL using the fair value option, the element of gains or losses attributable to changes in the own credit risk should normally be recognized in OCI, with the remainder recognized in profit or loss. These amounts recognized in OCI are not recycled to profit or loss even when the liability is derecognized. However, if presentation of the fair value change in respect of the liabilitys credit risk in OCI results in or enlarges an accounting mismatch in profit or loss, gains and losses are entirely presented in profit or loss.

Adoption of K-IFRS 1109 may result in decrease in profit or loss, since the amount of fair value changes that is attributable to changes in the credit risk of the liability will be presented in OCI.

As of December 31, 2016, the Companys total financial liability amounts to W 9,918,433 million, among which the financial liabilities designated as FVTPL using fair value option amount to W 59,600 million. Changes in fair value on financial liabilities designated as FVTPL using fair value option amounting to W 4,018 million was recognized as loss during the year ended December 31, 2016.

iii) Impairment: financial assets and contract assets

The current impairment requirements under K-IFRS No. 1039 are based on an incurred loss model, where the impairment exists if there is objective evidence as a result of one or more events that occurred after the initial recognition of an asset. However, K-IFRS No. 1109 replaces the incurred loss model in K-IFRS No. 1039 with an expected credit loss model which applies to debt instruments measured at amortized cost or at fair value through other comprehensive income.

Under K-IFRS No. 1109, the Company should recognize a loss allowance or provision at an amount equal to 12-month expected credit losses or lifetime expected credit losses for financial assets determined by the extent of probable credit deterioration since initial recognition as explained below. Therefore, the new impairment requirements are expected to result in earlier recognition of credit losses compared to the incurred loss model of K-IFRS No. 1039.

iii) Impairment: financial assets and contract assets, Continued

Stages (*1)		Loss allowances
Stage 1	No significant increase in credit risk since initial recognition (*2)	Loss allowances are determined for the amount of the expected credit losses that result from default events that are possible within 12 months after the reporting date.
Stage 2	Significant increase in credit risk since initial recognition	Loss allowances are determined for the amount of the expected credit losses that result from all possible default events over the expected life of the financial instrument.
Stage 3	Objective evidence of credit risk impairment

(*1) Under K-IFRS No. 1115, Revenue from Contracts with Customers (see note 3 (26) (2)), for trade receivables and contract assets arising with no significant credit risk, loss allowances are recognized at an amount equal to lifetime expected credit losses. However, for trade receivables and contract assets with a significant financing component arising under K-IFRS No. 1115, the Company may choose as its accounting policy to recognize loss allowances at an amount equal to lifetime expected credit losses. In addition, for receivables under lease arrangement, the Company may choose to recognize loss allowances at an amount equal to lifetime expected credit losses.

(*2) The Company may determine that a financial assets credit risk has not increased significantly if the asset has low credit risk at the reporting date.

K-IFRS No. 1109 allows the Company to only recognize the cumulative changes in lifetime expected credit losses since initial recognition as a loss allowance for purchased or originated credit-impaired financial assets at the reporting date. As of December 31, 2016, the Company has W 3,722,715 million of debt instrument financial assets measured at amortized cost and W 218,827 million as loss allowances for these assets.

iv) Hedge accounting

K-IFRS No. 1109 maintains the mechanics of hedge accounting from those in K-IFRS No. 1039. However, K-IFRS No. 1109 replaces existing rule-based requirements under K-IFRS No. 1039 that are complex and difficult to apply with principle based requirement focusing more on the Companys risk management purposes and procedures. Under K-IFRS No. 1109, more hedging instruments and hedged items are permitted and 80%-125% effectiveness requirement is removed.

By complying with the hedging rules in K-IFRS No. 1109, the Company may apply hedge accounting for transactions that currently do not meet the hedging criteria under K-IFRS No. 1039 thereby reducing volatility in profit or loss. As of December 31, 2016, the Company recognized the total amount of W 2,372,464 million as hedged liabilities that applied hedge accounting and changes in fair value of cash flow hedge in the amount of W 90,756 million was recognized in OCI for the year ended December 31, 2016.

Upon initial application of K-IFRS No. 1109, the Company may choose as its accounting policy to continue to apply hedge accounting requirements under K-IFRS No. 1039 instead of the requirements in K-IFRS No. 1109. The Company is still in the process of evaluating whether to make such accounting policy election upon adoption date.

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

K-IFRS No. 1115, Revenue from Contracts with Customers , published on November 6, 2015 is effective for annual periods beginning on or after January 1, 2018, with early adoption permitted. It replaces existing 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 Programmes , K-IFRS No. 2115, Agreements for the Construction of Real Estate , and K-IFRS No. 2118, Transfers of Assets from Customers . The Company plans to adopt K-IFRS No. 1115 on January 1, 2018. In accordance with the requirements in K-IFRS No. 1008, Accounting Policies, Changes in Accounting Estimates and Errors , and the transition guidance in K-IFRS No. 1115, the Company is considering to adopt K-IFRS No. 1115 using the retrospective approach.

K-IFRS No. 1018 provides separate revenue recognition criteria by transaction type which include sale of goods, rendering of services, and use of entity assets by others yielding interest, royalties and dividends. However, K-IFRS No. 1115 introduces a five-step model for revenue recognition that focuses on the transfer of control rather than the transfer of risks and rewards. The steps in five-step model are as follows:

identification of the contract with a customer;

identification of the performance obligations in the contract;

determination of the transaction price;

allocation of the transaction price to the performance obligations in the contract; and

recognition of revenue when (or as) the entity satisfies a performance obligation.

As of December 31, 2016, the Company has not yet changed its accounting process and internal controls related to revenue recognition.

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

The Company plans to change the accounting process and internal control and to assess the financial impact on its financial statements resulting from the adoption of K-IFRS No. 1115 by December 31, 2017. The impact of accounting changes on its financial statements that may arise from the adoption of K-IFRS No. 1115 is expected to include the following:

i) Identification of the separate performance obligations in the contract

A substantial portion of the Companys revenues are generated from provision of wireless telecommunications services. K-IFRS No. 1115 requires the Company to evaluate goods or services promised to customers to determine if they are performance obligations other than wireless telecommunications service that should be accounted for separately. The amount and timing of revenue recognition under K-IFRS No. 1105 may be different from those under K-IFRS No. 1018 depending on the conclusion over the existence of separately identifiable performance obligations and the timing of satisfying each performance obligation.

ii) Allocate the transaction price to the separate performance obligations

In accordance with K-IFRS No. 1115, the Company should allocate the transaction price to each performance obligation in a contract in proportion to their stand-alone selling price. The Company plans to use adjusted market assessment method for estimating the stand-alone selling price. However, in some circumstances, expected cost plus a margin approach will be used.

iii) Incremental costs to acquire a contract

The Company has exclusive contracts with its sales agents to sell the Companys wireless telecommunications services to subscribers. These agents receive commissions depending on the number of subscribers newly added and retained. The commissions paid to the agents constitute a significant portion of the Companys operating expenses. Currently, the portion of these commissions that would not have been incurred if there have been no binding contracts with the subscribers are expensed.

Under K-IFRS 1115, incremental costs to acquire a contract and certain costs to fulfill a contract are capitalized and amortized over the period the goods and services are delivered. However, as a practical expedient, the Company plans to expense the incremental cost as incurred if the amortization period of the contract acquisition and fulfillment cost is considered to be not longer than one year.

The recoverable amount of the CGU is based on its value in use calculated by applying the annual discount rate of 4.9% to the estimated future cash flows based on financial budgets for the next five years. An annual growth rate of 0.3% was applied for the cash flows expected to be incurred after five years and is not expected to exceed the Companys long-term wireless telecommunication business growth rate. Management of the Company 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.

Financial Risk Management

(1) Financial risk management

The Company 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, interest rates and equity prices. The Company implements a risk management system to monitor and manage these specific risks.

The Companys financial assets consist of cash and cash equivalents, financial instruments, available-for-sale financial assets, accounts receivable - trade and other. Financial liabilities consist of accounts payable - trade and other, borrowings, and debentures.

1) Market risk

(i) Currency risk

The Company is exposed to currency risk mainly on exchange fluctuations on forecasted transactions and recognized assets and liabilities which are denominated in a currency other than the functional currency of the Company.

Monetary assets and liabilities denominated in foreign currencies as of December 31, 2016 are as follows:

(In millions of won, thousands of foreign currencies)
Assets			Liabilities
Foreign currencies		Won translation	Foreign currencies		Won translation
USD	44,203	W	53,420	1,455,907	W	1,759,467
EUR	14,598		18,504	5		6
JPY	52,374		543

CHF				299,806		354,170
Others			368			299
		W	72,835		W	2,375,149

In addition, the Company has entered into cross currency swaps to hedge against currency risk related to foreign currency borrowings and debentures. (Refer to Note 15)

As of December 31, 2016, a hypothetical change in exchange rates by 10% would have increase (reduce) the Companys income before income tax as follows:

(In millions of won)	If increased by 10%	If decreased by 10%
USD	W	5,104	(5,104	)
EUR		1,850	(1,850	)
JPY		54	(54	)
Others		7	(7	)
	W	7,015	(7,015	)

(ii) Equity price risk

The Company has listed and non-listed equity securities for its liquidity management and operating purpose. As of December 31, 2016, available-for-sale equity instruments measured at fair value amount to W 522,491 million.

(iii) Interest rate risk

The interest rate risk of the Company arises from borrowings and debenture. Since the Companys interest bearing assets are mostly fixed-interest bearing assets, the Companys revenue and operating cash flows are not influenced by the changes in market interest rates.

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

As of December 31, 2016, floating-rate debentures amount to W 362,550 million and the Company has entered into interest rate swaps to hedge interest rate risk related to floating-rate borrowings and debentures (Refer to Note 15). Therefore, income before income taxes for the year ended December 31, 2016 would not have been affected by the changes in interest expenses from floating-rate borrowings and debentures in case of interest rate change.

2) Credit risk

The maximum credit exposure as of December 31, 2016 and 2015 are as follows:

(In millions of won)	2016	2015
Cash and cash equivalents	W	874,310	431,636

Financial assets at fair value through profit or loss		7,359	7,073
	W	3,909,429	2,762,698

Credit risk is the risk of financial loss to the Company if a customer or counterparty to a financial instrument fails to meet his/her contractual obligations.

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

The Company establishes an allowance for doubtful account that represents its estimate of incurred losses in respect of trade and other receivables. 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 have been incurred but not yet identified. The collective loss allowance is determined based on historical data of payment statistics for similar financial assets. Also, the Companys credit risk can arise due to transactions with financial institutions related to its cash and cash equivalents, financial instruments and derivatives. To minimize such risk, the Company has a policy to deal only with financial institutions with high credit ratings. The amount of maximum exposure to credit risk of the Company is the carrying amount of financial assets as of December 31, 2016.

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 128,456 million and W 155,849 million as of December 31, 2016 and December 31, 2015, respectively, are measured at cost in accordance with K-IFRS 1039 since they are equity instruments which do not have quoted price in an active market for the identical instruments (inputs for level 1) and for which fair value cannot be reliably measured using other valuation methods.

Table of Contents

Financial Risk Management, Continued

(3) Fair value, Continued

Fair value of the financial instruments that are traded in an active market (available-for-sale financial assets, financial liabilities at fair value through profit or loss, etc.) is measured based on the bid price at the end of the reporting date.

The Company uses various valuation methods for determination of fair value of financial instruments that are not traded in an active market. Fair value of available-for-sale securities is determined using the market approach methods and financial assets through profit or loss are measured using the option pricing model. In addition, derivative financial contracts and long-term liabilities are measured using the discounted present value methods. Inputs used to such valuation methods include swap rate, interest rate, and risk premium, and the Company performs valuation using the inputs which are consistent with natures of assets and liabilities measured.

Interest rates used by the Company for the fair value measurement as of December 31, 2016 are as follows:

	Interest rate
Derivative instruments	1.64 ~ 2.52%
Borrowings and debentures	2.09 ~ 2.14%
Long-term payables - other	1.79 ~ 2.27%

3) There have been no transfers from Level 2 to Level 1 in 2016 and changes of financial assets classified as Level 3 for the year ended December 31, 2016 are as follows:

English translation of a Report Originally Issued in Korean

To the Representative Director of

SK Telecom Co., Ltd.

We have reviewed the accompanying Report on the Operations of Internal Accounting Control System (IACS) of SK Telecom Co., Ltd. (the Company) As of December 31, 2016. The Companys management is responsible for designing and maintaining effective IACS and for its assessment of the effectiveness of IACS. Our responsibility is to review managements assessment and issue a report based on our review. In the accompanying report of managements assessment of IACS, the Companys management stated: Based on the assessment on the operations of the IACS, the Companys IACS has been effectively designed and is operating as of December 31, 2016, in all material respects, in accordance with the IACS Framework issued by the Internal Accounting Control System Operation Committee.

We conducted our review in accordance with IACS Review Standards, issued by the Korean Institute of Certified Public Accountants. Those Standards require that we plan and perform the review to obtain assurance of a level less than that of an audit as to whether Report on the Operations of Internal Accounting Control System is free of material misstatement. Our review consists principally of obtaining an understanding of the Companys IACS, inquiries of company personnel about the details of the report, and tracing to related documents we considered necessary in the circumstances. We have not performed an audit and, accordingly, we do not express an audit opinion.

A companys IACS is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Because of its inherent limitations, however, IACS may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Based on our review, nothing has come to our attention that Report on the Operations of Internal Accounting Control System as of December 31, 2016 is not prepared, in all material respects, in accordance with IACS Framework issued by the Internal Accounting Control System Operation Committee.

This report applies to the Companys IACS in existence as of December 31, 2016. We did not review the Companys IACS subsequent to December 31, 2016. This report has been prepared for Korean regulatory purposes, pursuant to the External Audit Law, and may not be appropriate for other purposes or for other users.
