(d) Use of Estimates and Judgments The preparation of the consolidated financial statements in conformity with IFRSs 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 in which the estimates are revised and in any future periods affected. Information about critical judgments in applying accounting policies that have the most significant effect on the amounts recognized in the consolidated financial statements is included in the following notes: • Classification of financial instruments (note 3.(e)) Information about assumptions and estimation uncertainties that have a significant risk of resulting in a material adjustment within the next 12 months is included in the following notes: • Recognition and measurement of provisions (note 3.(k), 13 and 15.(a)) • Measurement of defined benefit obligations (note 12) • Deferred tax assets and liabilities (note 24) |

Summary of Significant Accounting Policies | 3. Summary of Significant Accounting Policies The significant accounting policies followed by the Group in preparation of its consolidated financial statements are as follows: (a) Consolidation (i) Business combinations The Group accounts for business combinations using the acquisition method when control is transferred to the Group. The consideration transferred in the acquisition is generally measured at fair value, as are the identifiable net assets acquired. Any goodwill that arises is tested annually for impairment. Any gain on a bargain purchase is recognized in profit or loss immediately. Transaction costs are expensed as incurred, except if related to the issue of debt or equity securities in accordance with IAS 32 and IAS 39. The consideration transferred does not include amounts related to the settlement of pre-existing (ii) Subsidiaries Subsidiaries are entities controlled by the Group. The Group controls an entity when it is exposed, or has right to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. The financial statements of subsidiaries are included in the consolidated financial statements from the date on which control commences until the date on which control ceases. (iii) Non-controlling Non-controlling Changes in the Group’s interest in subsidiaries that do not result in a loss of control are accounted for as equity transactions. (iv) Loss of control If the Controlling Company loses control of subsidiaries, the Controlling Company derecognizes the assets and liabilities of the former subsidiaries from the consolidated statement of financial position and recognizes the gain or loss associated with the loss of control attributable to the former controlling interest. Meanwhile, the Controlling Company recognizes any investment retained in the former subsidiaries at its fair value when control is lost. (v) Associates and joint ventures (equity method investees) Associates are those entities in which the Group has significant influence, but not control or joint control, over the financial and operating policies. A joint venture is an arrangement in which the Group has joint control, whereby the Group has rights to the net assets of the arrangement, rather than rights to its assets and obligations for its liabilities. Investments in associates and joint ventures are initially recognized at cost and subsequently accounted for using the equity method of accounting. The carrying amount of investments in associates and joint ventures is increased or decreased to recognize the Group’s share of the profits or losses and changes in the Group’s proportionate interest of the investee after the date of acquisition. Distributions received from an investee reduce the carrying amount of the investment. If an associate or joint ventures uses accounting policies different from those of the Controlling Company for like transactions and events in similar circumstances, appropriate adjustments are made to the consolidated financial statements. As of and during the periods presented in the consolidated financial statements, no adjustments were made in applying the equity method. When the Group’s share of losses exceeds its interest in an equity accounted investee, the carrying amount of that interest, including any long-term investments, is reduced to nil, and the recognition of further losses is discontinued except to the extent that the Group has an obligation or has made payments on behalf of the investee. (vi) Transactions eliminated on consolidation Intra-group balances and transactions, including income and expenses and any unrealized income and expenses and balance of trade accounts and notes receivable and payable arising from intra-group transactions, are eliminated. Unrealized gains arising from transactions with equity-accounted investees are eliminated against the investment to the extent of the Group’s interest in the investee. Unrealized losses are eliminated in the same way as unrealized gains, but only to the extent that there is no evidence of impairment. (b) Foreign Currency Transactions and Translation Transactions in foreign currencies are translated to the respective functional currencies of the Group at exchange rates at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are retranslated to the functional currency at the exchange rate on the reporting date. Non-monetary available-for-sale Non-monetary non-operating If the presentation currency of the Group is different from a foreign operation’s functional currency, the financial position and financial performance 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, including goodwill and fair value adjustments arising on acquisition, are translated to the Group’s functional currency at exchange rates at the reporting date. The income and expenses of foreign operations are translated to the Group’s functional currency at exchange rates at the dates of the transactions. Foreign currency differences are recognized in other comprehensive income. However, if the operation is a non-wholly-owned non-controlling 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 at each reporting date’s exchange rate. (c) Cash and Cash Equivalents Cash and cash equivalents include all cash balances and short-term highly liquid investments with an original maturity of three months or less that are readily convertible into known amounts of cash. (d) Inventories Inventories are measured at the lower of cost and net realizable value. The cost of inventories is based on the weighted-average method, and includes expenditures incurred in acquiring the inventories, production or conversion costs and other costs incurred in bringing them to their existing location and condition. Net realizable value is the estimated selling price in the ordinary course of business less the estimated costs of completion and the estimated selling expenses. In the case of manufactured inventories and work-in-process, cost includes an appropriate share of production overheads based on the actual capacity of production facilities. However, the normal capacity is used for the allocation of fixed production overheads if the actual level of production is lower than the normal capacity. (e) Financial Instruments (i) Non-derivative The Group initially recognizes loans and receivables and deposits on the date they are originated. All other non-derivative The Group 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 of 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 a transfer does not result in derecognition because the Group has retained substantially all the risks and rewards of ownership of the transferred asset, the Group continues to recognize the transferred asset and recognizes a financial liability for the consideration received. In subsequent periods, the Group recognizes any income on the transferred assets and any expense incurred on the financial liability. Financial assets and liabilities are offset and the net amount presented in the consolidated statement of financial position when, and only when, the Group has a legal right to offset the amounts and intends either to settle them on a net basis or to realize the asset and settle the liability simultaneously. The Group has the following non-derivative available-for-sale Financial assets at fair value through profit or loss A financial asset is classified at FVTPL if it is classified as held for trading or is designated as such upon initial recognition. If a contract contains one or more embedded derivatives, the Group designates the entire hybrid (combined) contract as a financial asset at FVTPL unless: the embedded derivative(s) does not significantly modify the cash flows that otherwise would be required by the contract; or it is clear with little or no analysis when a similar hybrid (combined) instrument is first considered that separation of the embedded derivative(s) is prohibited. Upon initial recognition, attributable transaction costs are recognized in profit or loss as incurred. Financial assets at FVTPL are measured at fair value, and changes therein are recognized in profit or loss. Loans and receivables Loans and receivables are financial assets with fixed or determinable payments that are not quoted in an active market. When loans and receivables are recognized initially, the Group measures them at their fair value plus transaction costs that are directly attributable to the acquisition or issue of the financial asset. Subsequent to initial recognition, loans and receivables are measured at amortized cost using the effective interest method, less any impairment losses. Loans and receivables comprise trade accounts and notes receivable and other accounts receivable. Available-for-sale Available-for-sale non-derivative available-for-sale held-to-maturity available-for-sale available-for-sale available-for-sale Investments in equity instruments that do not have a quoted market price in an active market and whose fair value cannot be reliably measured and whose derivatives are linked to and must be settled by delivery of such unquoted equity instruments are measured at cost. (ii) Non-derivative The Group classifies financial liabilities into two categories, financial liabilities at FVTPL and other financial liabilities, in accordance with the substance of the contractual arrangement and the definitions of financial liabilities, and recognizes them in the consolidated statement of financial position when the Group becomes a party to the contractual provisions of the instrument. Financial liabilities at FVTPL include financial liabilities held for trading or designated as such upon initial recognition at FVTPL. After initial recognition, financial liabilities at FVTPL 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 issuance of financial liabilities are recognized in profit or loss as incurred. Non-derivative non-derivative The Group derecognizes a financial liability when its contractual obligations are discharged, cancelled or expired. (iii) Share capital The Group only issued common stocks and they are classified as equity. Incremental costs directly attributable to the issuance of common stocks are recognized as a deduction from equity, net of tax effects. Capital contributed in excess of par value upon issuance of common stocks is classified as share premium within equity. (iv) Derivative financial instruments 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. Hedge accounting If necessary, the Group designates derivatives as hedging items 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). On initial designation of the hedge, the Group’s management formally designates and 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, both at the inception of the hedge relationship as well as on an ongoing basis. i) Fair value hedges Change in the fair value of a derivative hedging instrument designated as a fair value hedge and the hedged item is recognized in profit or loss, respectively. The gain or loss from remeasuring the hedging instrument at fair value 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 comprehensive income. The Group discontinues fair value hedge accounting if it does not designate the derivative hedging instrument and the hedged item as the hedge relationship between them anymore or 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. ii) Cash flow hedges When a derivative designated as a cash flow hedging instrument meets the criteria of cash flow hedge accounting, the effective portion of changes in the fair value of the derivative is recognized in other comprehensive income and the ineffective portion of changes in the fair value of the derivative is recognized in profit or loss. The Group discontinues cash flow hedge accounting if it does not designate the derivative hedging instrument and the hedged item as the hedge relationship between them any more or if the hedging instruments expires or is sold, terminated or exercised, or if the hedge no longer meets the criteria for hedge accounting. 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. Embedded derivative Embedded derivatives are separated from the host contract and accounted for separately if the economic characteristics and risks of the host contract and the embedded derivative are not closely related, a separate instrument with the same terms as the embedded derivative would meet the definition of a derivative, and the combined instrument is not measured at FVTPL. Changes in the fair value of separable embedded derivatives are recognized immediately in profit or loss. Other derivative financial instruments Derivative financial instruments are measured at fair value and changes of them not designated as a hedging instrument or not effective for hedging are recognized in profit or loss. (f) Property, Plant and Equipment (i) Recognition and measurement Items of property, plant and equipment are measured at cost less accumulated depreciation and accumulated impairment losses. Cost includes an expenditure that is directly attributable to the acquisition of the asset. The cost of self-constructed assets includes the cost of materials and direct labor, any costs directly attributable to bringing the assets to a working condition for their intended use, the costs of dismantling and removing the items and restoring the site on which they are located and borrowing costs on qualifying assets. The gain or loss arising from the derecognition of an item of property, plant and equipment is determined as the difference between the net disposal proceeds, if any, and the carrying amount of the item and recognized in other non-operating non-operating (ii) Subsequent costs Subsequent expenditure on an item of property, plant and equipment is recognized as part of its cost only 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 measured reliably. The costs of the day-to-day (iii) Depreciation Depreciation is recognized in profit or loss on a straight-line basis, reflecting the pattern in which the asset’s future economic benefits are expected to be consumed by the Group. The residual value of property, plant and equipment is zero. Land is not depreciated. Estimated useful lives of the assets are as follows: Useful lives (years) Buildings and structures 20, 40 Machinery 4, 5 Furniture and fixtures 4 Equipment, tools and vehicles 4, 12 Depreciation methods, useful lives and residual values are reviewed at each financial year-end (g) Borrowing Costs The Group capitalizes borrowing costs, which includes interests and exchange differences arising from foreign currency borrowings to the extent that they are regarded as an adjustment to interest costs, directly attributable to the acquisition, construction or production of a qualifying asset as part of the cost of that asset. A qualifying asset is an asset that necessarily takes a substantial period of time to get ready for its intended use or sale. 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. The Group immediately recognizes other borrowing costs as an expense. (h) Government Grants In case there is reasonable assurance that the Group will comply with the conditions attached to a government grant, the government grant is recognized as follows: (i) Grants related to the purchase or construction of assets A government grant related to the purchase or construction of assets is 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 reduced depreciation expense and cash related to grant received is presented in investing activities in the statement of cash flows. (ii) Grants for compensating the Group’s expenses incurred A government grant that compensates the Group for expenses incurred is recognized in profit or loss as a deduction from relevant expenses on a systematic basis in the periods in which the expenses are recognized. (iii) Other government grants A government grant that becomes receivable for the purpose of giving immediate financial support to the Group with no compensation for expenses or losses already incurred or no future related costs is recognized as income of the period in which it becomes receivable. (i) Intangible Assets Intangible assets are initially measured at cost. Subsequently, intangible assets are measured at cost less accumulated amortization and accumulated impairment losses. (i) Goodwill Goodwill arising from business combinations is recognized as the excess of the acquisition cost of investments in subsidiaries, associates and joint ventures over the Group’s share of the net fair value of the identifiable assets acquired and liabilities assumed. Any deficit is a bargain purchase that is recognized in profit or loss. Goodwill is measured at cost less accumulated impairment losses. (ii) Research and development Expenditure on research activities, undertaken with the prospect of gaining new scientific or technical knowledge and understanding, is recognized in profit or loss as incurred. Development activities involve a plan or design of the production of new or substantially improved products and processes. Development expenditure is capitalized only if the Group can demonstrate all of the following: • the technical feasibility of completing the intangible asset so that it will be available for use or sale, • its intention to complete the intangible asset and use or sell it, • its ability to use or sell the intangible asset, • how the intangible asset will generate probable future economic benefits. Among other things, the Group can demonstrate the existence of a market for the output of the intangible asset or the intangible asset itself or, if it is to be used internally, the usefulness of the intangible asset, • the availability of adequate technical, financial and other resources to complete the development and to use or sell the intangible asset, and • its ability to measure reliably the expenditure attributable to the intangible asset during its development. The expenditure capitalized includes the cost of materials, direct labor, overhead costs that are directly attributable to preparing the asset for its intended use, and borrowing costs on qualifying assets. (iii) Other intangible assets Other intangible assets include intellectual property rights, software, customer relationships, technology, memberships and others. (iv) Subsequent costs Subsequent expenditure is capitalized only when it increases the future economic benefits embodied in the specific intangible asset to which it relates. All other expenditure, including expenditure on internally generated goodwill and brands, is recognized in profit or loss as incurred. (v) Amortization Amortization is calculated on a straight-line basis over the estimated useful lives of intangible assets, other than goodwill, from the date that they are available for use. The residual value of intangible assets is zero. However, as there are no foreseeable limits to the periods over which condominium and golf club memberships are expected to be available for use, these intangible assets are regarded as having indefinite useful lives and not amortized. Estimated useful lives (years) Intellectual property rights 5, 10 Rights to use electricity, water and gas supply facilities 10 Software 4 Customer relationships 7, 10 Technology 10 Development costs (*) Condominium and golf club memberships Not amortized (*) Capitalized development costs are amortized over the useful life considering the life cycle of the developed products. Amortization of capitalized development costs is recognized in research and development expenses in the consolidated statement of comprehensive income. Amortization periods and the amortization methods for intangible assets with finite useful lives are reviewed at each financial year-end. (j) Impairment (i) Financial assets A financial asset not carried at FVTPL 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. Objective evidence that financial assets are impaired can include default or delinquency in interest or principal payments by an issuer or a debtor, for economic reasons relating to the borrower’s financial difficulty, granting to the borrower a concession that the Group would not otherwise consider, or the disappearance of an active market for that financial asset. In addition, for an investment in an equity security, objective evidence of impairment includes significant financial difficulty of the issuer and a significant or prolonged decline in its fair value below its cost. Management considers evidence of impairment for loans and receivables at both a specific asset and collective level. All individually significant loans and receivables are assessed for specific impairment. All individually significant receivables found not to be specifically impaired are then collectively assessed for any impairment that has been incurred but not yet identified. Loans and receivables that are not individually significant are collectively assessed for impairment by grouping together receivables with similar risk characteristics. In assessing collective impairment the Group uses historical trends of the probability of default, timing of recoveries and the amount of loss incurred, adjusted for management’s judgment as to whether current economic and credit conditions are such that the actual losses are likely to be greater or less than suggested by historical trends. If there is objective evidence that an impairment loss has been incurred on financial assets carried at amortized cost, the amount of the impairment loss is measured as the difference between its carrying amount and the present value of the estimated future cash flows discounted at the asset’s original effective interest rate. Impairment losses are recognized in profit or loss and reflected in an allowance account against loans and receivables. The amount of the impairment loss on financial assets including equity securities carried at cost is measured as the difference between the carrying amount 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. When a decline in the fair value of an available-for-sale In a subsequent period, for the financial assets recorded at fair value, if the fair value increases and the increase can be objectively related to an event occurring after the impairment loss was recognized, the previously recognized impairment loss is reversed. The amount of the reversal in financial assets carried at amortized cost and a debt instrument classified as available for sale is recognized in profit or loss. However, impairment loss recognized for an investment in an equity instrument classified as available-for-sale (ii) Non-financial The carrying amounts of the Group’s non-financial For the purpose of impairment testing, assets that cannot be tested individually are grouped together into the smallest group of assets that generates cash inflows from continuing use that are largely independent of the cash inflows of other assets or groups of assets (the “cash-generating unit”, or “CGU”). The recoverable amount of an asset or cash-generating unit is determined as the greater of its value in use and its fair value less costs to sell. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax An impairment loss is recognized if the carrying amount of an asset or its CGU exceeds its estimated recoverable amount. Impairment losses are recognized in profit or loss. Goodwill acquired in a business combination is allocated to CGUs that are expected to benefit from the synergies of the combination. Impairment losses recognized in respect of a CGU are allocated first to reduce the carrying amount of any goodwill allocated to the unit, and then to reduce the carrying amounts of the other assets in the unit on a pro rata basis. In respect of other assets, impairment losses recognized in prior periods are assessed at each reporting date for any indications that the loss has decreased or no longer exists. 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 accumulated depreciation or amortization, if no impairment loss had been recognized. An impairment loss in respect of goodwill is not reversed. A provision is recognized if, as a result of a past event, the Group has a present legal or constructive obligation that can be estimated reliably, and it is probable that an outflow of economic benefits will be required to settle the obligation. The risks and uncertainties that inevitably surround 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. The unwinding of the discount is recognized as finance cost. Provisions are reviewed at the end of each reporting period and adjusted to reflect the current best estimate. 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. The Group recognizes a liability for warranty obligations based on the estimated costs expected to be incurred under its basic limited warranty. This warranty covers defective products and is normally applicable for eighteen months from the date of purchase. These liabilities are accrued when product revenues are recognized. Factors that affect the Group’s warranty liability include historical and anticipated rates of warranty claims on those repairs and cost per claim to satisfy the Group’s warranty obligation. Warranty costs primarily include raw materials and labor costs. As these factors are impacted by actual experience and future expectations, management periodically assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary. Accrued warranty obligations are included in the current and non-current Liabilities for loss contingencies arising from claims, assessments, litigation, fines, and penalties and other sources, are recorded when it is probable that a liability has been incurred and the amount of the assessment and/or remediation can be reasonably estimated. (l) Employee Benefits (i) Short-term employee benefits Short-term employee benefits that are due to be settled within twelve months after the end of the period in which the employees render the related service are recognized in profit or loss on an undiscounted basis. The expected cost of profit-sharing and bonus plans and others are recognized when the Group has a present legal or constructive obligation to make payments as a result of past events and a reliable estimate of the obligation can be made. (ii) Other long-term employee benefits The Group’s net obligation in respect of long-term employee benefits other than pension plans is the amount of future benefit that employees have earned in return for their service in the current and prior periods. (iii) Defined contribution plan A defined contribution plan is a post-employment benefit plan under which an entity pays fixed contributions into a separate entity and will have no legal or constructive obligation to pay further amounts. Obligations for contributions to defined contribution pension plans are recognized as an employee benefit expense in profit or loss in the periods during which services are rendered by employees. (iv) Defined benefit plan A defined benefit plan is a post-employment benefit plan other than defined contribution plans. The Group’s net obligation in respect of its defined benefit plan is calculated by estimating 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. The fair value of any plan assets is deducted. The calculation is performed annually by an independent actuary using the projected unit credit method. The discount rate is the yield at the reporting date on high quality corporate bonds that have maturity dates approximating the terms of the Group’s obligations and that are denominated in the same currency in which the benefits are expected to be paid. The Group recognizes all actuarial gains and losses arising from defined benefit plans in retained earnings immediately. The Group determines the net interest expense (income) on the net defined benefit liability (asset) for the period by applying the discount rate used to measure the defined benefit obligation at the beginning of the annual period to the then-net When the benefits of a plan are changed or when a plan is curtailed, the resulting change in benefit that relates to past service or the gain or loss on curtailment is recognized immediately in profit or loss. The Group recognizes gains and losses on the settlement of a defined benefit plan when the settlement occurs. (m) Revenue Revenue from the sale of goods in the course of ordinary activities is measured at the fair value of the consideration received or receivable, net of estimated returns, earned trade discounts, volume rebates and other cash incentives paid to customers. Revenue is recognized when persuasive evidence exists that the significant risks and rewards of ownership have been transferred to the buyer, generally on delivery and acceptance at the customers’ premises, recovery of the consideration is probable, the associated costs and possible return of goods can be estimat |

Financial Risk Management | 26. Financial Risk Management The Group is exposed to credit risk, liquidity risk and market risks. The Group identifies and analyzes such risks, and controls are implemented under a risk management system to monitor and manage these risks at below a threshold level. (a) Market Risk Market risk is the risk that changes in market prices, such as foreign exchange rates, interest rates and equity prices, will affect the Group’s income or the value of its holdings of financial instruments. The objective of market risk management is to manage and control market risk exposures within acceptable parameters, while optimizing the return. (i) Currency Risk The Group is exposed to currency risk on sales, purchases and borrowings that are denominated in a currency other than the functional currency of the Controlling Company, Korean won (KRW). The currencies in which these transactions primarily are denominated are USD, CNY, JPY, etc. Interest on borrowings is denominated in the currency of the borrowing. Generally, borrowings are denominated in currencies that match the cash flows generated by the underlying operations of the Group, primarily KRW and USD. In respect of other monetary assets and liabilities denominated in foreign currencies, the Group adopts policies to ensure that its net exposure is kept to an acceptable level by buying or selling foreign currencies at spot rates when necessary to address short-term imbalances. i) Exposure to currency risk The Group’s exposure to foreign currency risk based on notional amounts at the reporting date is as follows: (In millions) December 31, 2016 USD JPY CNY TWD EUR PLN VND Cash and cash equivalents 518 308 3,785 36 1 77 338,770 Deposits in banks — — 500 — — — — Trade accounts and notes receivable 3,558 10 1,776 — — — — Non-trade 52 2,434 199 12 — 2 — Long-term non-trade 2 — — — — — — Other assets denominated in foreign currencies 1 259 210 6 — — 506 Trade accounts and notes payable (1,204 ) (14,940 ) (2,567 ) — — — — Other accounts payable (397 ) (9,836 ) (771 ) (7 ) (2 ) (5 ) (665,869 ) Borrowings (1,251 ) — (3,264 ) — — — — Net exposure 1,279 (21,765 ) (132 ) 47 (1 ) 74 (326,593 ) (In millions) December 31, 2017 USD JPY CNY TWD EUR PLN VND Cash and cash equivalents 1,228 152 6,940 16 3 165 342,063 Deposits in banks — — 750 — — — — Trade accounts and notes receivable 3,316 11 1,453 — — — — Non-trade 62 1,340 136 2 9 — 13,405 Other assets denominated in foreign currencies 1 206 596 7 — — 1,882 Trade accounts and notes payable (1,345 ) (14,898 ) (2,843 ) — — — (102,398 ) Other accounts payable (285 ) (14,653 ) (2,403 ) (11 ) (8 ) (4 ) (2,138,370 ) Borrowings (1,500 ) — (3,263 ) — — — — Net exposure 1,477 (27,842 ) 1,366 14 4 161 (1,883,418 ) Significant exchange rates applied during the reporting periods are as follows: (In won) Average rate Reporting date spot rate 2015 2016 2017 December 31, December 31, USD W 1,131.30 1,159.83 1,131.08 1,208.50 1,071.40 JPY 9.35 10.67 10.09 10.37 9.49 CNY 179.47 174.40 167.52 173.26 163.65 TWD 35.64 35.97 37.16 37.41 35.92 EUR 1,256.17 1,283.95 1,277.01 1,267.60 1,279.25 PLN 300.22 294.41 299.98 287.62 306.07 VND 0.0516 0.0518 0.0498 0.0531 0.0472 ii) Sensitivity analysis A weaker won, as indicated below, against the following currencies which comprise the Group’s assets or liabilities denominated in a foreign currency as of December 31, 2016 and 2017, would have increased (decreased) equity and profit or loss by the amounts shown below. This analysis is based on foreign currency exchange rate variances that the Group considers to be reasonably possible as of the end of the reporting period. The analysis assumes that all other variables, in particular interest rates, would remain constant. The changes in equity and profit or loss would have been as follows: (In millions of won) December 31, 2016 December 31, 2017 Equity Profit or Equity Profit or USD (5 percent weakening) W 57,111 63,337 50,040 91,238 JPY (5 percent weakening) (8,972 ) (7,237 ) (10,294 ) (9,141 ) CNY (5 percent weakening) (3,410 ) 7,077 13,212 (6,396 ) TWD (5 percent weakening) 88 — 23 1 EUR (5 percent weakening) (40 ) (79 ) 16 594 PLN (5 percent weakening) 1,129 (167 ) 2,515 (120 ) VND (5 percent weakening) (867 ) — (4,445 ) — A stronger won against the above currencies as of December 31, 2016 and 2017 would have had the equal but opposite effect on the above currencies to the amounts shown above, on the basis that all other variables remain constant. (ii) Interest rate risk Interest rate risk arises principally from the Company’s bonds and borrowings. The Company establishes and applies its policy to reduce uncertainty arising from fluctuations in the interest rate and to minimize finance cost and manages interest rate risk by monitoring of trends of fluctuations in interest rate and establishing plan for countermeasures. i) Profile The interest rate profile of the Group’s interest-bearing financial instruments at the reporting date is as follows: (In millions of won) December 31, 2016 December 31, 2017 Fixed rate instruments Financial assets W 2,722,600 3,360,800 Financial liabilities (2,203,378 ) (2,962,671 ) W 519,222 398,129 Variable rate instruments Financial liabilities W (2,575,392 ) (2,640,447 ) ii) Equity and profit or loss sensitivity analysis for variable rate instruments For the years ended December 31, 2016 and 2017 a change of 100 basis points in interest rates at the reporting date would have increased (decreased) equity and profit or loss by the amounts shown below for the respective following years. This analysis assumes that all other variables, in particular foreign currency rates, remain constant. (In millions of won) Equity Profit or loss 1% increase 1% decrease 1% increase 1% decrease December 31, 2016 Variable rate instruments(*) W (16,868 ) 16,868 (16,868 ) 16,868 December 31, 20167 Variable rate instruments(*) W (17,362 ) 17,362 (17,362 ) 17,362 (*) Financial instruments subject to interest rate swap not qualified for hedging are excluded. (b) Credit risk Credit risk is the risk of financial loss to the Group if a customer or counterparty to a financial instrument fails to meet its contractual obligations, and arises principally from the Group’s receivables from customers. The Group’s exposure to credit risk of trade and other receivables is influenced mainly by the individual characteristics of each customer. However, management believes that the demographics of the Group’s customer base, including the default risk of the country in which customers operate, do not have a significant influence on credit risk since the majority of the customers are global electronic appliance manufacturers operating in global markets. The Group establishes credit limits for each customer and each new customer is analyzed quantitatively and qualitatively before determining whether to utilize third party guarantees, insurance or factoring as appropriate. The Group does not establish allowances for receivables under insurance or receivables from customers with a high credit rating. For the rest of the receivables, the Group establishes an allowance for impairment of trade and other receivables that have been individually or collectively evaluated for impairment and estimated on the basis of historical loss experience for assets. The carrying amount of financial assets represents the maximum credit exposure. The maximum exposure to credit risk at the reporting date are as follows: (In millions of won) December 31, 2016 December 31, 2017 Cash and cash equivalents W 1,558,696 2,602,560 Deposits in banks 1,163,763 758,089 Trade accounts and notes receivable, net 4,957,993 4,325,120 Non-trade 134,161 150,554 Accrued income 9,431 14,273 Available-for-sale 154 162 Financial assets at fair value through profit or loss 1,382 1,552 Deposits 47,954 30,378 Short-term loans 7,696 16,766 Long-term loans 34,760 32,408 Long-term non-trade 2,619 8,738 Derivatives 244 842 W 7,918,853 7,941,442 Credit risk is the risk of financial loss to the Group if a customer or counterparty to a financial instrument fails to meet its contractual obligations, and arises primarily from the sales and investing activities. Trade accounts and notes receivables are insured in order to manage credit risk and uninsured trade accounts and notes receivables are managed in accordance with the Group’s management policy. (c) Liquidity Risk Liquidity risk is the risk that the Group will encounter difficulty in meeting the obligations associated with its financial liabilities that are settled by delivering cash or another financial asset. The Group’s approach to managing liquidity is to ensure, as far as possible, that it will always have sufficient liquidity to meet its liabilities when due, under both normal and stressed conditions, without incurring unacceptable losses or risking damage to the Group’s reputation. The Group has historically been able to satisfy its cash requirements from cash flows from operations and borrowings and equity financing. To the extent that the Group does not generate sufficient cash flows from operations to meet its capital requirements, the Group may rely on other financing activities, such as external long-term borrowings and offerings of debt securities, equity-linked and other debt securities. In addition, the Group maintains a line of credit with various banks. The following are the contractual maturities of financial liabilities, including estimated interest payments, as of December 31, 2017. (In millions of won) Contractual cash flows Carrying Total 6 months 6-12 1-2years 2-5 More than Non-derivative Secured bank borrowings W 642,172 660,540 258,027 145,804 256,709 — — Unsecured bank borrowings 2,950,184 3,112,199 36,579 596,101 1,107,718 1,176,097 195,704 Unsecured bond issues 2,010,762 2,124,147 413,307 134,829 592,031 983,980 — Trade accounts and notes payable 2,875,090 2,875,090 2,875,090 — — — — Other accounts payable 3,169,937 3,170,157 3,169,790 367 — — — Long-term other accounts payable 2 2 — — 2 — — W 11,648,147 11,942,135 6,752,793 877,101 1,956,460 2,160,077 195,704 It is not expected that the cash flows included in the maturity analysis could occur significantly earlier, or at significantly different amounts. (d) Capital Management Management’s policy is to maintain a capital base so as to maintain investor, creditor and market confidence and to sustain future development of the business. Liabilities to equity ratio, net borrowings to equity ratio and other financial ratios are used by management to achieve an optimal capital structure. Management also monitors the return on capital as well as the level of dividends to ordinary shareholders. (In millions of won) December 31, 2016 December 31, 2017 Total liabilities W 11,421,948 14,178,177 Total equity 13,462,388 14,981,510 Cash and deposits in banks (*1) 2,722,446 3,360,638 Borrowings (including bonds) 4,778,770 5,603,118 Total liabilities to equity ratio 85% 95% Net borrowings to equity ratio (*2) 15% 15% (*1) Cash and deposits in banks consist of cash and cash equivalents and current deposit in banks. (*2) Net borrowings to equity ratio is calculated by dividing total borrowings (including bonds) less cash and current deposits in banks by total equity. (e) Determination of fair value (i) Measurement of fair value A number of the Group’s accounting policies and disclosures require the determination of fair value, for both financial and non-financial i) Other current financial assets and liabilities The carrying amounts approximate fair value because of the short maturity of these instruments. ii) Trade Receivables and Other Receivables The fair value of trade and other receivables is estimated as the present value of future cash flows, discounted at the market rate of interest at the reporting date.

Consolidation | (a) Consolidation (i) Business combinations The Group accounts for business combinations using the acquisition method when control is transferred to the Group. The consideration transferred in the acquisition is generally measured at fair value, as are the identifiable net assets acquired. Any goodwill that arises is tested annually for impairment. Any gain on a bargain purchase is recognized in profit or loss immediately. Transaction costs are expensed as incurred, except if related to the issue of debt or equity securities in accordance with IAS 32 and IAS 39. The consideration transferred does not include amounts related to the settlement of pre-existing (ii) Subsidiaries Subsidiaries are entities controlled by the Group. The Group controls an entity when it is exposed, or has right to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. The financial statements of subsidiaries are included in the consolidated financial statements from the date on which control commences until the date on which control ceases. (iii) Non-controlling Non-controlling Changes in the Group’s interest in subsidiaries that do not result in a loss of control are accounted for as equity transactions. (iv) Loss of control If the Controlling Company loses control of subsidiaries, the Controlling Company derecognizes the assets and liabilities of the former subsidiaries from the consolidated statement of financial position and recognizes the gain or loss associated with the loss of control attributable to the former controlling interest. Meanwhile, the Controlling Company recognizes any investment retained in the former subsidiaries at its fair value when control is lost. (v) Associates and joint ventures (equity method investees) Associates are those entities in which the Group has significant influence, but not control or joint control, over the financial and operating policies. A joint venture is an arrangement in which the Group has joint control, whereby the Group has rights to the net assets of the arrangement, rather than rights to its assets and obligations for its liabilities. Investments in associates and joint ventures are initially recognized at cost and subsequently accounted for using the equity method of accounting. The carrying amount of investments in associates and joint ventures is increased or decreased to recognize the Group’s share of the profits or losses and changes in the Group’s proportionate interest of the investee after the date of acquisition. Distributions received from an investee reduce the carrying amount of the investment. If an associate or joint ventures uses accounting policies different from those of the Controlling Company for like transactions and events in similar circumstances, appropriate adjustments are made to the consolidated financial statements. As of and during the periods presented in the consolidated financial statements, no adjustments were made in applying the equity method. When the Group’s share of losses exceeds its interest in an equity accounted investee, the carrying amount of that interest, including any long-term investments, is reduced to nil, and the recognition of further losses is discontinued except to the extent that the Group has an obligation or has made payments on behalf of the investee. (vi) Transactions eliminated on consolidation Intra-group balances and transactions, including income and expenses and any unrealized income and expenses and balance of trade accounts and notes receivable and payable arising from intra-group transactions, are eliminated. Unrealized gains arising from transactions with equity-accounted investees are eliminated against the investment to the extent of the Group’s interest in the investee. Unrealized losses are eliminated in the same way as unrealized gains, but only to the extent that there is no evidence of impairment. |
Foreign Currency Transactions and Translation | (b) Foreign Currency Transactions and Translation Transactions in foreign currencies are translated to the respective functional currencies of the Group at exchange rates at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are retranslated to the functional currency at the exchange rate on the reporting date. Non-monetary available-for-sale Non-monetary non-operating If the presentation currency of the Group is different from a foreign operation’s functional currency, the financial position and financial performance 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, including goodwill and fair value adjustments arising on acquisition, are translated to the Group’s functional currency at exchange rates at the reporting date. The income and expenses of foreign operations are translated to the Group’s functional currency at exchange rates at the dates of the transactions. Foreign currency differences are recognized in other comprehensive income. However, if the operation is a non-wholly-owned non-controlling 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 at each reporting date’s exchange rate. |
Cash and Cash Equivalents | (c) Cash and Cash Equivalents Cash and cash equivalents include all cash balances and short-term highly liquid investments with an original maturity of three months or less that are readily convertible into known amounts of cash. |
Inventories | (d) Inventories Inventories are measured at the lower of cost and net realizable value. The cost of inventories is based on the weighted-average method, and includes expenditures incurred in acquiring the inventories, production or conversion costs and other costs incurred in bringing them to their existing location and condition. Net realizable value is the estimated selling price in the ordinary course of business less the estimated costs of completion and the estimated selling expenses. In the case of manufactured inventories and work-in-process, cost includes an appropriate share of production overheads based on the actual capacity of production facilities. However, the normal capacity is used for the allocation of fixed production overheads if the actual level of production is lower than the normal capacity. |
Financial Instruments | (e) Financial Instruments (i) Non-derivative The Group initially recognizes loans and receivables and deposits on the date they are originated. All other non-derivative The Group 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 of 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 a transfer does not result in derecognition because the Group has retained substantially all the risks and rewards of ownership of the transferred asset, the Group continues to recognize the transferred asset and recognizes a financial liability for the consideration received. In subsequent periods, the Group recognizes any income on the transferred assets and any expense incurred on the financial liability. Financial assets and liabilities are offset and the net amount presented in the consolidated statement of financial position when, and only when, the Group has a legal right to offset the amounts and intends either to settle them on a net basis or to realize the asset and settle the liability simultaneously. The Group has the following non-derivative available-for-sale Financial assets at fair value through profit or loss A financial asset is classified at FVTPL if it is classified as held for trading or is designated as such upon initial recognition. If a contract contains one or more embedded derivatives, the Group designates the entire hybrid (combined) contract as a financial asset at FVTPL unless: the embedded derivative(s) does not significantly modify the cash flows that otherwise would be required by the contract; or it is clear with little or no analysis when a similar hybrid (combined) instrument is first considered that separation of the embedded derivative(s) is prohibited. Upon initial recognition, attributable transaction costs are recognized in profit or loss as incurred. Financial assets at FVTPL are measured at fair value, and changes therein are recognized in profit or loss. Loans and receivables Loans and receivables are financial assets with fixed or determinable payments that are not quoted in an active market. When loans and receivables are recognized initially, the Group measures them at their fair value plus transaction costs that are directly attributable to the acquisition or issue of the financial asset. Subsequent to initial recognition, loans and receivables are measured at amortized cost using the effective interest method, less any impairment losses. Loans and receivables comprise trade accounts and notes receivable and other accounts receivable. Available-for-sale Available-for-sale non-derivative available-for-sale held-to-maturity available-for-sale available-for-sale available-for-sale Investments in equity instruments that do not have a quoted market price in an active market and whose fair value cannot be reliably measured and whose derivatives are linked to and must be settled by delivery of such unquoted equity instruments are measured at cost. (ii) Non-derivative The Group classifies financial liabilities into two categories, financial liabilities at FVTPL and other financial liabilities, in accordance with the substance of the contractual arrangement and the definitions of financial liabilities, and recognizes them in the consolidated statement of financial position when the Group becomes a party to the contractual provisions of the instrument. Financial liabilities at FVTPL include financial liabilities held for trading or designated as such upon initial recognition at FVTPL. After initial recognition, financial liabilities at FVTPL 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 issuance of financial liabilities are recognized in profit or loss as incurred. Non-derivative non-derivative The Group derecognizes a financial liability when its contractual obligations are discharged, cancelled or expired. (iii) Share capital The Group only issued common stocks and they are classified as equity. Incremental costs directly attributable to the issuance of common stocks are recognized as a deduction from equity, net of tax effects. Capital contributed in excess of par value upon issuance of common stocks is classified as share premium within equity. (iv) Derivative financial instruments 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. Hedge accounting If necessary, the Group designates derivatives as hedging items 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). On initial designation of the hedge, the Group’s management formally designates and 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, both at the inception of the hedge relationship as well as on an ongoing basis. i) Fair value hedges Change in the fair value of a derivative hedging instrument designated as a fair value hedge and the hedged item is recognized in profit or loss, respectively. The gain or loss from remeasuring the hedging instrument at fair value 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 comprehensive income. The Group discontinues fair value hedge accounting if it does not designate the derivative hedging instrument and the hedged item as the hedge relationship between them anymore or 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. ii) Cash flow hedges When a derivative designated as a cash flow hedging instrument meets the criteria of cash flow hedge accounting, the effective portion of changes in the fair value of the derivative is recognized in other comprehensive income and the ineffective portion of changes in the fair value of the derivative is recognized in profit or loss. The Group discontinues cash flow hedge accounting if it does not designate the derivative hedging instrument and the hedged item as the hedge relationship between them any more or if the hedging instruments expires or is sold, terminated or exercised, or if the hedge no longer meets the criteria for hedge accounting. 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. Embedded derivative Embedded derivatives are separated from the host contract and accounted for separately if the economic characteristics and risks of the host contract and the embedded derivative are not closely related, a separate instrument with the same terms as the embedded derivative would meet the definition of a derivative, and the combined instrument is not measured at FVTPL. Changes in the fair value of separable embedded derivatives are recognized immediately in profit or loss. Other derivative financial instruments Derivative financial instruments are measured at fair value and changes of them not designated as a hedging instrument or not effective for hedging are recognized in profit or loss. |
Property, Plant and Equipment | (f) Property, Plant and Equipment (i) Recognition and measurement Items of property, plant and equipment are measured at cost less accumulated depreciation and accumulated impairment losses. Cost includes an expenditure that is directly attributable to the acquisition of the asset. The cost of self-constructed assets includes the cost of materials and direct labor, any costs directly attributable to bringing the assets to a working condition for their intended use, the costs of dismantling and removing the items and restoring the site on which they are located and borrowing costs on qualifying assets. The gain or loss arising from the derecognition of an item of property, plant and equipment is determined as the difference between the net disposal proceeds, if any, and the carrying amount of the item and recognized in other non-operating non-operating (ii) Subsequent costs Subsequent expenditure on an item of property, plant and equipment is recognized as part of its cost only 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 measured reliably. The costs of the day-to-day (iii) Depreciation Depreciation is recognized in profit or loss on a straight-line basis, reflecting the pattern in which the asset’s future economic benefits are expected to be consumed by the Group. The residual value of property, plant and equipment is zero. Land is not depreciated. Estimated useful lives of the assets are as follows: Useful lives (years) Buildings and structures 20, 40 Machinery 4, 5 Furniture and fixtures 4 Equipment, tools and vehicles 4, 12 Depreciation methods, useful lives and residual values are reviewed at each financial year-end |
Borrowing Costs | (g) Borrowing Costs The Group capitalizes borrowing costs, which includes interests and exchange differences arising from foreign currency borrowings to the extent that they are regarded as an adjustment to interest costs, directly attributable to the acquisition, construction or production of a qualifying asset as part of the cost of that asset. A qualifying asset is an asset that necessarily takes a substantial period of time to get ready for its intended use or sale. 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. The Group immediately recognizes other borrowing costs as an expense. |
Government Grants | (h) Government Grants In case there is reasonable assurance that the Group will comply with the conditions attached to a government grant, the government grant is recognized as follows: (i) Grants related to the purchase or construction of assets A government grant related to the purchase or construction of assets is 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 reduced depreciation expense and cash related to grant received is presented in investing activities in the statement of cash flows. (ii) Grants for compensating the Group’s expenses incurred A government grant that compensates the Group for expenses incurred is recognized in profit or loss as a deduction from relevant expenses on a systematic basis in the periods in which the expenses are recognized. (iii) Other government grants A government grant that becomes receivable for the purpose of giving immediate financial support to the Group with no compensation for expenses or losses already incurred or no future related costs is recognized as income of the period in which it becomes receivable. |
Intangible Assets | (i) Intangible Assets Intangible assets are initially measured at cost. Subsequently, intangible assets are measured at cost less accumulated amortization and accumulated impairment losses. (i) Goodwill Goodwill arising from business combinations is recognized as the excess of the acquisition cost of investments in subsidiaries, associates and joint ventures over the Group’s share of the net fair value of the identifiable assets acquired and liabilities assumed. Any deficit is a bargain purchase that is recognized in profit or loss. Goodwill is measured at cost less accumulated impairment losses. (ii) Research and development Expenditure on research activities, undertaken with the prospect of gaining new scientific or technical knowledge and understanding, is recognized in profit or loss as incurred. Development activities involve a plan or design of the production of new or substantially improved products and processes. Development expenditure is capitalized only if the Group can demonstrate all of the following: • the technical feasibility of completing the intangible asset so that it will be available for use or sale, • its intention to complete the intangible asset and use or sell it, • its ability to use or sell the intangible asset, • how the intangible asset will generate probable future economic benefits. Among other things, the Group can demonstrate the existence of a market for the output of the intangible asset or the intangible asset itself or, if it is to be used internally, the usefulness of the intangible asset, • the availability of adequate technical, financial and other resources to complete the development and to use or sell the intangible asset, and • its ability to measure reliably the expenditure attributable to the intangible asset during its development. The expenditure capitalized includes the cost of materials, direct labor, overhead costs that are directly attributable to preparing the asset for its intended use, and borrowing costs on qualifying assets. (iii) Other intangible assets Other intangible assets include intellectual property rights, software, customer relationships, technology, memberships and others. (iv) Subsequent costs Subsequent expenditure is capitalized only when it increases the future economic benefits embodied in the specific intangible asset to which it relates. All other expenditure, including expenditure on internally generated goodwill and brands, is recognized in profit or loss as incurred. (v) Amortization Amortization is calculated on a straight-line basis over the estimated useful lives of intangible assets, other than goodwill, from the date that they are available for use. The residual value of intangible assets is zero. However, as there are no foreseeable limits to the periods over which condominium and golf club memberships are expected to be available for use, these intangible assets are regarded as having indefinite useful lives and not amortized. Estimated useful lives (years) Intellectual property rights 5, 10 Rights to use electricity, water and gas supply facilities 10 Software 4 Customer relationships 7, 10 Technology 10 Development costs (*) Condominium and golf club memberships Not amortized (*) Capitalized development costs are amortized over the useful life considering the life cycle of the developed products. Amortization of capitalized development costs is recognized in research and development expenses in the consolidated statement of comprehensive income. Amortization periods and the amortization methods for intangible assets with finite useful lives are reviewed at each financial year-end. |
Impairment | (j) Impairment (i) Financial assets A financial asset not carried at FVTPL 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. Objective evidence that financial assets are impaired can include default or delinquency in interest or principal payments by an issuer or a debtor, for economic reasons relating to the borrower’s financial difficulty, granting to the borrower a concession that the Group would not otherwise consider, or the disappearance of an active market for that financial asset. In addition, for an investment in an equity security, objective evidence of impairment includes significant financial difficulty of the issuer and a significant or prolonged decline in its fair value below its cost. Management considers evidence of impairment for loans and receivables at both a specific asset and collective level. All individually significant loans and receivables are assessed for specific impairment. All individually significant receivables found not to be specifically impaired are then collectively assessed for any impairment that has been incurred but not yet identified. Loans and receivables that are not individually significant are collectively assessed for impairment by grouping together receivables with similar risk characteristics. In assessing collective impairment the Group uses historical trends of the probability of default, timing of recoveries and the amount of loss incurred, adjusted for management’s judgment as to whether current economic and credit conditions are such that the actual losses are likely to be greater or less than suggested by historical trends. If there is objective evidence that an impairment loss has been incurred on financial assets carried at amortized cost, the amount of the impairment loss is measured as the difference between its carrying amount and the present value of the estimated future cash flows discounted at the asset’s original effective interest rate. Impairment losses are recognized in profit or loss and reflected in an allowance account against loans and receivables. The amount of the impairment loss on financial assets including equity securities carried at cost is measured as the difference between the carrying amount 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. When a decline in the fair value of an available-for-sale In a subsequent period, for the financial assets recorded at fair value, if the fair value increases and the increase can be objectively related to an event occurring after the impairment loss was recognized, the previously recognized impairment loss is reversed. The amount of the reversal in financial assets carried at amortized cost and a debt instrument classified as available for sale is recognized in profit or loss. However, impairment loss recognized for an investment in an equity instrument classified as available-for-sale (ii) Non-financial The carrying amounts of the Group’s non-financial For the purpose of impairment testing, assets that cannot be tested individually are grouped together into the smallest group of assets that generates cash inflows from continuing use that are largely independent of the cash inflows of other assets or groups of assets (the “cash-generating unit”, or “CGU”). The recoverable amount of an asset or cash-generating unit is determined as the greater of its value in use and its fair value less costs to sell. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax An impairment loss is recognized if the carrying amount of an asset or its CGU exceeds its estimated recoverable amount. Impairment losses are recognized in profit or loss. Goodwill acquired in a business combination is allocated to CGUs that are expected to benefit from the synergies of the combination. Impairment losses recognized in respect of a CGU are allocated first to reduce the carrying amount of any goodwill allocated to the unit, and then to reduce the carrying amounts of the other assets in the unit on a pro rata basis. In respect of other assets, impairment losses recognized in prior periods are assessed at each reporting date for any indications that the loss has decreased or no longer exists. 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 accumulated depreciation or amortization, if no impairment loss had been recognized. An impairment loss in respect of goodwill is not reversed. |
Provisions | A provision is recognized if, as a result of a past event, the Group has a present legal or constructive obligation that can be estimated reliably, and it is probable that an outflow of economic benefits will be required to settle the obligation. The risks and uncertainties that inevitably surround 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. The unwinding of the discount is recognized as finance cost. Provisions are reviewed at the end of each reporting period and adjusted to reflect the current best estimate. 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. The Group recognizes a liability for warranty obligations based on the estimated costs expected to be incurred under its basic limited warranty. This warranty covers defective products and is normally applicable for eighteen months from the date of purchase. These liabilities are accrued when product revenues are recognized. Factors that affect the Group’s warranty liability include historical and anticipated rates of warranty claims on those repairs and cost per claim to satisfy the Group’s warranty obligation. Warranty costs primarily include raw materials and labor costs. As these factors are impacted by actual experience and future expectations, management periodically assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary. Accrued warranty obligations are included in the current and non-current Liabilities for loss contingencies arising from claims, assessments, litigation, fines, and penalties and other sources, are recorded when it is probable that a liability has been incurred and the amount of the assessment and/or remediation can be reasonably estimated. |
Employee Benefits | (l) Employee Benefits (i) Short-term employee benefits Short-term employee benefits that are due to be settled within twelve months after the end of the period in which the employees render the related service are recognized in profit or loss on an undiscounted basis. The expected cost of profit-sharing and bonus plans and others are recognized when the Group has a present legal or constructive obligation to make payments as a result of past events and a reliable estimate of the obligation can be made. (ii) Other long-term employee benefits The Group’s net obligation in respect of long-term employee benefits other than pension plans is the amount of future benefit that employees have earned in return for their service in the current and prior periods. (iii) Defined contribution plan A defined contribution plan is a post-employment benefit plan under which an entity pays fixed contributions into a separate entity and will have no legal or constructive obligation to pay further amounts. Obligations for contributions to defined contribution pension plans are recognized as an employee benefit expense in profit or loss in the periods during which services are rendered by employees. (iv) Defined benefit plan A defined benefit plan is a post-employment benefit plan other than defined contribution plans. The Group’s net obligation in respect of its defined benefit plan is calculated by estimating 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. The fair value of any plan assets is deducted. The calculation is performed annually by an independent actuary using the projected unit credit method. The discount rate is the yield at the reporting date on high quality corporate bonds that have maturity dates approximating the terms of the Group’s obligations and that are denominated in the same currency in which the benefits are expected to be paid. The Group recognizes all actuarial gains and losses arising from defined benefit plans in retained earnings immediately. The Group determines the net interest expense (income) on the net defined benefit liability (asset) for the period by applying the discount rate used to measure the defined benefit obligation at the beginning of the annual period to the then-net When the benefits of a plan are changed or when a plan is curtailed, the resulting change in benefit that relates to past service or the gain or loss on curtailment is recognized immediately in profit or loss. The Group recognizes gains and losses on the settlement of a defined benefit plan when the settlement occurs. |
Revenue | (m) Revenue Revenue from the sale of goods in the course of ordinary activities is measured at the fair value of the consideration received or receivable, net of estimated returns, earned trade discounts, volume rebates and other cash incentives paid to customers. Revenue is recognized when persuasive evidence exists that the significant risks and rewards of ownership have been transferred to the buyer, generally on delivery and acceptance at the customers’ premises, 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. If it is probable that discounts will be granted and the amount can be measured reliably, then the discount is recognized as a reduction of revenue when the sales are recognized. Sales taxes collected from customers and remitted to governmental authorities are accounted for on a net basis and therefore are excluded from revenues in the consolidated statements of comprehensive income. |
Operating Segments | (n) Operating Segments An operating segment is a component of the Group that: 1) engages in business activities from which it may earn revenues and incur expenses, including revenues and expenses that relate to transactions with other components of the group, 2) whose operating results are reviewed regularly by the Group’s chief operating decision maker (“CODM”) in order to allocate resources and assess its performance, and 3) for which discrete financial information is available. Management has determined that the CODM of the Group is the Board of Directors. The CODM does not receive and therefore does not review discrete financial information for any component of the Group. Consequently, no operating segment information is included in these consolidated financial statements. Entity wide disclosures of geographic and product revenue information are provided in note 17 to these consolidated financial statements. |
Finance Income and Finance Costs | (o) Finance Income and Finance Costs Finance income comprises interest income on funds invested (including available-for-sale available-for-sale Finance costs comprise interest expense on borrowings, unwinding of the discount on provisions, changes in the fair value of financial assets at FVTPL, impairment losses recognized on financial assets, and losses on hedging instruments that are recognized in profit or loss. Borrowing costs directly attributable to the acquisition, construction or production of a qualifying asset are capitalized as part of the cost of that asset. |
Income Tax | (p) Income Tax 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. (i) Current tax Current tax is the expected tax payable or receivable on the taxable profit or loss for the year, using tax rates enacted or substantively enacted at the reporting date 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 non-deductible (ii) Deferred tax Deferred tax is recognized, using the 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. 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. However, deferred tax is not recognized for taxable temporary differences arising on the initial recognition of goodwill. The Group recognizes a deferred tax liability for all taxable temporary differences associated with investments in subsidiaries, associates, and interests in joint ventures, except to the extent that the Group is able to control the timing of the reversal of the temporary differences and it is probable that the temporary differences will not reverse in the foreseeable future. A deferred tax asset is recognized for all deductible temporary differences to the extent that it is probable that the differences relating to investments in subsidiaries, associates and joint ventures will reverse in the foreseeable future and taxable profit will be available against which the temporary difference can be utilized. Deferred tax assets are reviewed at each reporting date and are reduced to the extent that it is no longer probable that the related tax benefit will be realized. The Group offsets deferred tax assets and deferred tax liabilities if, and only if the Group has a legally enforceable right to set off current tax assets against current tax liabilities and the deferred tax assets and the deferred tax liabilities relate to income taxes levied by the same taxation authority on either the same taxable entity or different taxable entities which intend either to settle current tax liabilities and assets on a net basis, or to realize the assets and settle the liabilities simultaneously. |
Earnings Per Share | (q) Earnings Per Share The Controlling Company presents basic and diluted earnings per share (“EPS”) data for its common stocks. Basic EPS is calculated by dividing the profit or loss attributable to ordinary shareholders of the Controlling Company by the weighted average number of common stocks outstanding during the period. Diluted EPS is determined by adjusting the profit or loss attributable to ordinary shareholders and the weighted average number of common stocks outstanding, adjusted for the effects of all dilutive potential common stocks such as convertible bonds and others. |
Change in Accounting Policies | The Group has consistently applied the accounting policies to the consolidated financial statements for 2016 and 2017 except for the new amendments effective for annual periods beginning on January 1, 2017 as mentioned below. (i) IAS 7, Statement of Cash Flows The Group has adopted the amendment to IAS 7, Statement of Cash Flows non-cash non-cash (ii) IAS 12, Income Taxes The Group has adopted the amendment to IAS 12, Income Taxes |
New Standards and Amendments Not Yet Adopted | (s) New Standards and Amendments Not Yet Adopted The following new standards and amendments to existing standards have been published and are mandatory for the Group for annual periods beginning after January 1, 2017, and the Group has not early adopted them. (i) IFRS 9, Financial Instruments IFRS 9, Financial Instruments Financial Instruments: Recognition and Measurement Adoption of IFRS 9 will generally be applied retrospectively, except as described below. • Advantage of exemption allowing the Group not to restate comparative information for prior periods with respect to classification, measurement and impairment changes. • Prospective application of new hedge accounting except for those specified in IFRS 9 for retrospective application such as accounting for the time value of options and others. During the year ended December 31, 2017, the Group performed analysis and identified necessary modifications to internal controls and the accounting system in preparation of adoption of IFRS 9. Management believes that the adoption of the amendment is expected to have no significant impact on the consolidated financial statements of the Group. The potential general impact on its consolidated financial statements resulting from the application of new standards are as follows. Classification and Measurement of Financial Assets IFRS 9 contains three principal classification categories for financial assets: measured at amortized cost, fair value through other comprehensive income (“FVOCI”) and fair value through profit or loss (“FVTPL”), based on the business model in which assets are managed and their cash flow characteristics. However, derivatives embedded in contracts where the host is a financial assets in the scope of the standard are never bifurcated. Instead, the hybrid financial instrument as a whole is assessed for classification. Business model assessment Contractual cash flow characteristics Solely payments of Others Hold to collect contractual cash flows Amortized cost (*1) Hold to collect contractual cash flows and sell financial assets FVOCI FVTPL (*2) Hold to sell financial assets and others FVTPL (*1) The Group may irrevocably designate a financial asset as measured at FVTPL using the fair value option at initial recognition if doing so eliminates or significantly reduces accounting mismatch. (*2) The Group may irrevocably designate an equity investment that is not held for trading as measured at FVOCI using the fair value option. The requirements to classify financial assets as amortized cost or FVOCI under IFRS 9 are more restrictive than them under IAS 39. Accordingly, increase in proportion of financial assets classified as FVTPL may result in increase of volatility in profit or loss of the Group. As of December 31, 2017, the Group recognized W W available-for-sale W A debt investment is measured at amortized cost under IFRS 9 if it meets both of the following conditions: • The asset is held within a business model whose objective is achieved by collecting contractual cash flows; and • The contractual terms of the financial asset give rise on specified dates to cash flow that are solely payments of principal and interest on the principal amount outstanding. As of December 31, 2017, the Group recognized W A debt investment is measured at FVOCI under IFRS 9 if it meets both of the following conditions: • The asset is held within a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets; and • The contractual terms of the financial asset give rise on specified dates to cash flow that are solely payments of principal and interest on the principal amount outstanding. As of December 31, 2017, the Group recognized W available-for-sale Equity investment that are not held for trading may be irrevocably designated as FVOCI on initial recognition under IFRS 9 and they are not subsequently recycled to profit or loss. As of December 31, 2017, the Group recognized W available-for-sale A financial asset is measured at FVTPL under IFRS 9, if: • The asset’s contractual cash flows do not represent solely payments of principal and interest on the principal amount outstanding; • Debt instrument is held for trading; or • Equity instrument is not designated as FVOCI. As of December 31, 2017, the Group recognized W Based on the evaluation to date, upon adoption of IFRS 9, W available-for-sale Classification and Measurement of Financial Liabilities Under IFRS 9, the amount of change in the fair value of liabilities designated as at FVTPL that is attributable to changes in the credit risk of the liability is not presented in the item of profit or loss, but in OCI and they are not subsequently recycled to profit or loss. However, if accounting mismatch is created or enlarged as a result of this accounting treatment, the amount of change in the credit risk of the financial liabilities is also recognized as profit or loss. Adoption of IFRS 9 may result in decrease of volatility in profit or loss in relation to evaluation of financial liabilities as some of change in the fair value of financial liabilities designated as at FVTPL is presented in OCI. As of December 31, 2017, there was no financial liabilities measured at FVTPL. Impairment: Financial assets and contract assets Impairment loss is recognized if there is any objective evidence that a financial asset or group of financial asset is impaired according to ‘incurred loss model’ under IAS 39. However, IFRS 9 replaces the incurred loss model in IAS 39 with an ‘expected credit loss impairment model’ which applies to debt instruments measured at amortized cost or at fair value through other comprehensive income, lease receivable, loan commitments and financial guarantee contracts. Under IFRS 9, loss allowance is classified into three stages below in accordance with increase of credit risk after initial recognition of financial assets and measured on the 12-month Classification Loss allowances Stage 1 No significant increase in credit risk since initial recognition 12-month Stage 2 Significant increase in credit risk since initial recognition Lifetime expected credit losses: 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 Under IFRS 9, cumulative change in lifetime expected credit loss since initial recognition is recognized as a loss allowance for financial asset, if it was credit-impaired at initial recognition. As of December 31, 2017, under IAS 39, the Group recognized W W Hedge accounting When initially applying IFRS 9, the Group may choose as its accounting policy to continue to apply hedge accounting requirements under IAS 39 instead of the requirements in IFRS 9. The Group determined to consistently apply hedge accounting requirements of IAS 39. (ii) IFRS 15, Revenue from contracts with customers IFRS 15, Revenue from contracts with customers Construction Contracts SIC-31, Revenue: Barter Transactions Involving Advertising Services Customer Loyalty Programmes Agreements for the Construction of Real Estate Transfers of Assets from Customers Revenue recognition criteria in IAS 18 are applied separately to each transaction including sale of goods, rendering of services, interest, royalties, dividends and construction contracts. However, IFRS 15 establishes a single new revenue recognition standard for contracts with customers and introduces a five-step model for determining whether, how much and when revenue is recognized. The steps in five-step model are as follows: a) Identify the contract with a customer. b) Identify the performance obligations in the contract. c) Determine the transaction price. d) Allocate the transaction price to the performance obligations in the contract. e) Recognize revenue when (or as) the entity satisfies a performance obligation. During the year ended December 31, 2017, the Group assessed the financial impact of the adoption of IFRS 15 on its consolidated financial statements. As a result, the potential impact on its consolidated financial statements resulting from the application of the new standard is as follows. Variable Consideration The consideration received from customers may be variable as the Group allows its customers to return their products according to the contracts. Currently, the Group recognizes a provision measured at the gross profit for products sold which are expected to be returned. Under IFRS 15, the Group shall estimate an amount of variable consideration by using the expected value or the most likely amount, depending on which method the Group expects to better predict the amount of consideration to which it will be entitled and include in the transaction price some or all of an amount of variable consideration estimated only to the extent that is highly probable that a significant reversal in the amount of cumulative revenue recognized will not occur when return period expires. The Group shall recognize refund liability measured at the amount of consideration received (or receivable) to which the Group does not expect to be entitled and a new asset for the right to recover returned goods. As a result of this change, it is expected that the refund liability and a new asset for the right to recover returned goods will be increased by W (iii) IFRS 16, Leases IFRS 16, Leases Leases Determining whether an Arrangement contains a Lease SIC-15, Operating Leases—Incentives SIC-27, valuating the Substance of Transactions Involving the Legal Form of a Lease At inception of a contract, the Group assesses whether the contract is, or contains, a lease and reassess whether a contract is, or contains, a lease at the date of initial application. However, as a practical expedient, the Group is not required to reassess for contracts entered into, or changed, on or before January 1, 2019. The Group is currently assessing the potential impact on its consolidated financial statements resulting from the application of IFRS 16. (iv) IFRIC 22, Foreign Currency Transactions and Advance Consideration According to the new interpretation, IFRIC 22, Foreign Currency Transactions and Advance Consideration non-monetary non-monetary |
