dart.fss.or.kr Page 22 II. Business Activities

1. Business Overview

A. System IC The Company is in the business of manufacturing and selling core parts (System IC) that drive display panels, and consists of a single display business division.

1) Characteristics of the industry The products have been growing in scale with the development of the display industry as a key component to drive the display panel. The key competitive factor in the display parts market is to strengthen technological competitiveness based on the original technology and to enter the market in the early stage of display technology development. As the complex product designing technology is demanded recently, technology gap is getting bigger between companies that accomplished differentiated technology and those who have not.

2) Market scale and growth The medium and large scale (TV/IT/automotive) display IC market is growing in size thanks to qualitative growth due to the increasing proportion of premium products such as high-resolution (8K) LCDs and OLED TVs, as well as aggressive investments made by Chinese panel makers in LCD TVs. In addition, in the small (smart phone/smart watch) display IC market, starting with Apple's first P-OLED phone release (2017), Chinese panel producers are accelerating their entry into the P-OLED market, and it is expected to have a continuous growth centered on P-OLED products in the future. As such, the display IC market is expected to grow continuously due to the rapid growth of Chinese panel makers and the trend of panel generation conversion.

[Annual panel sales]

① Medium and large sized (TV/ IT/Auto) Display IC The display IC market for LCD TVs is growing on the rise of the number of ICs per panel with the increased panel volume due to aggressive investments by Chinese panel makers and the increase in the proportion of UHD panels. The UHD TV penetration rate in 2020 is expected to be about 53% on a global average, and in particular, the spread of 8K TVs is also growing, leading the growth of display ICs for LCD TVs.

dart.fss.or.kr Page 23 In addition, the proportion of OLED TVs in the premium TV market is increasing steadily, and the number of TV set makers who have selected OLED panels as a strategy for product differentiation is increasing. The display IC market for large OLED TVs is also showing high growth. The market size is small as LG Display is the only company that is mass-producing OLED TV panels so far. However, rapid growth is expected in the future as Chinese panel producers are making aggressive facility investments based on enormous capital power. Unlike LCD products, display ICs for OLED TVs are based on panel compensation technology in addition to driving technology, so companies with competitive power are expected to lead the market. IT products are expected to increase in short-term demand due to the expansion of the non-face-to-face living environment caused by COVID-19. In addition, some premium brands are increasing the added value by adding new functions such as increasing the resolution and utilizing the touch panel.

② Small (smart phone/smart watch) Display IC The smartphone market has entered the stage of maturity. The smartphone panel market size was about 1.6 billion units in 2018 and 2019, and is expected to reach about 1.5 billion units by 2020 with a decreased demand caused by the global economic downturn. The smartphone market in developed countries is expected to grow less than that of the emerging market, and the growth of the emerging market is driving the growth of the overall smartphone market. In particular, global mobile demand is greatly affected by the trend of the Chinese domestic market. Furthermore, as the market share of local set makers in the Chinese market is increasing, the Chinese set customers are becoming important, and this is expected to continue as the market conditions change due to the trade dispute between the US and China. Major global set makers are actively pursuing Form Factor evolution strategies to create new demand, so it is expected that the proportion of smartphones equipped with P-OLED panels will increase continuously. Domestic and overseas panel makers are expanding investment in P-OLED facilities. Currently, domestic panel makers are leading the P-OLED market due to the technological gap between Korean and Chinese panel makers, but Chinese makers' share in the P-OLED panel market is expected to gradually increase as the makers expand their capacity. Unlike the decline in demand in the smartphone market, the smart watch market is expected to continue to grow at a high level every year, and the size of the related market is expected to increase continuously through services linked to various devices such as IoT in the future.

(3) Characteristics of economic fluctuations and competitive elements The core competitive element in the display component market is the market entry at the initial stage with the development of display, as well as the strengthening technological competitiveness based on original technologies. It is to create a barrier to entry with differentiation through technological competitiveness by securing a meaningful share in a new market where new technologies are applied. The display industry is a field that requires both technology and capital-intensive characteristics and economies of scale, and has the characteristic that the barrier to entry increases as the degree of technical completion increases. In the past, the supply capacity has improved through fierce competition among panel makers, and in line with the increase in demand, the overall display industry has recorded a high growth rate. However, due to the high maturity of the market and limited demand in recent years, it has entered a low-growth phase. Due to its high sensitivity to economic fluctuations, replacement demand does not increase significantly. Without creating new demand through innovative products, it is difficult to expect continuous growth in the market.

dart.fss.or.kr Page 24 (4) Market share According to a market research firm Omdia, based on the year 2019, we maintained the 60th place in the global semiconductor companies ranking, and in the top 3 among display driver IC companies. In recent years, securing competitive power in new technologies rather than the size of sales itself has become an important criterion for determining the Company's competitive advantage. Thus, we are successfully entering the premium market such as OLED/P-OLED through close cooperation with panel and set customers. In addition to the display, we are also continuing to expand our business to new areas such as home appliances and automobiles.

(5) Strength of the Company The company not only provides the core components of Display System Semiconductor as a total solution, but also localizes the products that have been highly dependent on imports, contributing to stable parts procurement and price competitiveness of domestic downstream companies. We are also actively supporting customer's market by providing customized premium products by making continuous technology development. The win-win strategy based on trust with forward-looking companies plays a major role in our strong competitive power. Through these efforts, we have secured technological response power to comply with market change in more prompt and flexible ways than other companies, which includes new product development and delivery. Accordingly, the Company is realizing customer diversification through securing domestic and overseas customers based on our unique design technological power.

B. Silicon Works Inc. (USA), Silicon Works China Co., Ltd. (China) The Company has overseas subsidiaries in the US and China to open up new markets and support existing customers. Please refer to "A. System IC" for the characteristics of the two overseas subsidiaries and the size of their markets.

3) Sales strategy The Company is expected to maintain its competitive power in the market through the development of new products and technologies as well as differentiated customer support for strengthening the customer base and expanding new customers. Also, it will keep its market status by providing the optimum solutions requested by customers as tailor made products.

6. Order Situation

Driver chips for displays manufactured by the Company have various types based on the size and characteristics of display panels. Based on the characteristics of purchase policies of major panel providers, order for the necessary amount is placed in a cycle of about 10 weeks, followed by additional requests made at any given time thereafter.

7. Market Risk and Risk Management

The Group is exposed to credit risk, liquidity risk and market risk with regard to financial products. Information on the risk to which the Group is exposed is disclosed in the notes with the goal, policy, risk evaluation and management procedure, and capital management of the Group. Additional quantitative information is also disclosed throughout these financial statements.

dart.fss.or.kr Page 27 A. Credit risk management Credit risk refers to risk where the Group may have financial losses as customers or transactional counterpart fails to fulfill contractual obligations for financial products, and it mainly occurs at account receivables for customers and investment assets. The Company is trading with customers with the certain level or higher of credit rating in an effort to reduce financial losses due to default, while reviewing the credit ratings of customers with exposure to credit risk periodically. Credit risk may break out even from transactions with financial institutions as well, and in principle, the Company is trading only with the banks of higher credit ranking in an effort to reduce this risk. The Company ensures that new transactions are carried out for deposits with the higher likelihood of credit risk such as trust deposits only after approval by the executive in charge. The exposure level of the Group to credit risk in the current quarter is maximum 489.6 billion KRW, including cash, cashable assets, trade receivables and other receivables.

B. Liquidity risk management Maintaining and managing adequate liquidity is a very important matter for the Company. The Company currently maintains non-debt management and has an adequate cash level. In addition, we are making every effort to maintain and manage appropriate liquidity through periodic forecasting of funds balance, estimating the required cash level, and managing income and expenses. Separately, we are actively communicating with the financial market to secure early liquidity in preparation for liquidity risks, and also reviewing overdraft and other borrowing limits to secure abundant liquidity.

C. Market risk Market risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate due to changes in market prices.

1) Exchange rate risk management The Group is exposed to the exchange rate risk related to the sales profits and costs indicated in KRW, which is the functioning currency. The major presentation currency for these transactions is USD. The following are the carrying amounts of the cash assets and liabilities presented in foreign currency other than the functioning currency at the end of the current and last years: (Unit: million won) End of the current year End of the last year Division USD JPY CNY USD JPY CNY Assets in foreign 131,674.0 0.0 0.0 81,228.8 0.0 0.0 currency Liabilities in 28,619.7 0.1 0.2 19,536.8 0.4 0.2 foreign currency The following are the effect of the changes in foreign exchange rate for Korean won (before income tax) on the losses and gains for the current and last years: (Unit: million won) End of the current year End of the last year Division (If 5% changed) (If 5% changed) USD ±5,153 ±3,085

dart.fss.or.kr Page 28 JPY ±0 ±0 CNY ±0 ±0

2) Interest rate risk management The Group is not treating the fixed interest rate financial products as the financial products for which the profits or losses should be recognized in the current fiscal year. Therefore, the revenues and operating cash flows of the Group are actually independent of variations in the market interest rate.

D. Capital risk management The capital management of the Group is for maintaining the existence of the Company as a going concern, minimizing the capital cost for funding, maximizing the profits of the shareholders, and maintaining an appropriate equity structure. The Group is managing its capital based on the liability ratio. The Group manages the capital based on the ratio of liability, which is calculated by dividing the total liability in the financial statement with capital. In the current quarter, the Group maintains a proper liability ratio at 41.02%.

2. Preparation standards of the consolidated financial statements The consolidated financial statements of the Company and its subsidiaries (hereinafter referred to as the "Group") were prepared in accordance with K-IFRS. Important accounting policies that were applied to preparation of the consolidated financial statements are described below, and the policies applied to preparation of the consolidated financial statements of the current year are the same as those adopted in the preparation of the annual consolidated financial statements for the fiscal year ending 31 December 2019, except for impacts related to the introduction of the standard or interpretation described below. The consolidated financial statements have been prepared on a historical cost basis, excluding certain non- current assets and financial assets that are measured at revaluation or fair value at the end of each reporting period, as described in the accounting policies below. In general, the historical cost is measured at the fair value of the consideration paid to acquire the asset. Fair value is the price that will be received on the sale of an asset or paid on the transfer of liabilities in the normal transaction between market participants at the measurement date, regardless of whether the price is directly observable or estimated using a valuation technique. In estimating the fair value of an asset or liability, the Group takes into account the characteristics of the assets or liabilities that the market participant considers when determining the price of the assets or liabilities at the measurement date. Fair

dart.fss.or.kr Page 41 value for measurement or disclosure purposes is determined in accordance with the principles described above, except for measurements that are in part similar to fair value but not fair value such as stock-based payment transactions included in the scope of application of Statement of Korea Accounting Standards (hereinafter referred to as SKAS) No.1102 ‘Stock-based payment’, lease transactions included in the scope of application of SKAS No.1116 'Lease’, net realizable value of SKAS No.1002 'Inventories’, and value in use of SKAS No.1036 'Impairment of assets’. Management has a reasonable expectation that at the time of approval of the financial statements, the Group will have sufficient resources to survive as a going concern for the foreseeable future period. Therefore, management has prepared the consolidated financial statements based on the premise that the Group is a going concern. The Group's consolidated financial statements is approved by the board of directors on 27 January 2021 and will finally approved by the shareholder’s meeting which will be held at 18 March 2021.

1) The new standards and interpretations introduced from current quarter and the resulting changes in accounting policies are as follows: - K-IFRS No.1109 ‘financial instruments’ and K-IFRS No.1107 ‘financial instruments: disclosure’ (revision) - Impact of the initial application of interest rate index reform This amendment revised specific hedging accounting requirements to ensure that hedging accounting can continue to be applied for a period of uncertainty before the hedged items or hedging instruments affected by the current interest rate indicator is changed as a result of the ongoing interest rate indicator reform. This amendment is not related to the Group, since the Group does not apply hedging accounting.

- SKAS No.1116 Lease (amendment) - practical and simple method for rent discounts related to COVID- 19 This amendment provides practical relief for lessees to account for rent discounts, etc., arising as a direct result of COVID-19. The practical and simple method allows the lessee to choose not to evaluate whether the COVID-19-related rental discount, etc., qualifies as a lease change. The lessee who has made this choice will account for changes in lease fees due to the COVID-19-related rental fee discount, etc., consistent with the method that the lessee accounts for when such changes are not lease changes. • The practical and simple method applies only to rental discount discounts, etc., which have occurred as a direct result of COVID 19, and is applied when all of the following conditions are met. • The lease consideration corrected due to the change in lease payments is substantially the same as or less than the lease consideration before the change. • The lease fee reduction only affects the lease payments due before 30 June 2021 (for example, these conditions are met if a rent discount decreases the lease payment owed before 30 May 2021, and increases the lease after 30 May 2021). • Other lease periods and conditions are not practically changed.

- Reference to the 'Conceptual System' in the K-IFRS (amendment) Refer to the fully revised 'Conceptual System' (2018) of SKAS for this amendment. However, not all amendments will require that phrases related to such references or citations that refers to the fully revised

dart.fss.or.kr Page 42 'Conceptual System' (2018). Some phrases indicate whether the referenced ‘Conceptual System' is a 'Conceptual System’ for the preparation and presentation of financial statements' (2007), a 'Conceptual System' (2010), or a newly revised Conceptual System' (2018). For clarification, some other text has been revised to clarify that the definition in the K-IFRS has not been changed to the new definition developed in the fully revised 'Conceptual System' (2018). This document contains revisions to K-IFRS No.1102, No.1103, No.1106, No.1114, No.1001, No.1008, No.1034, No.1037, No.1038, No.2112, No.2119, No.2120, No.2122 and No.2032.

- Business definition under K-IFRS No.1103 (amendment) This amendment clarifies that although projects generally have deliverables, outputs are not essential for an integrated set of activities and assets to meet the definition of a business. In order for the set of acquired activities and assets to be considered a business, they must at least contain inputs and substantive processes that have the ability to contribute significantly together in the creation of outputs. This amendment removes the evaluation of whether market participants can replace missing inputs or processes and continue to produce output. It also provides guidelines for judgment to help the participants to decide whether or not a substantial course has been acquired. This amendment introduced an optional intensive test that can briefly evaluate whether a set of acquired activities and assets is a business. In this selective intensive test, if the fair value of the total assets acquired is substantially concentrated in a single identifiable asset or a group of identifiable similar assets, this is not a business. This amendment applies to business combinations after the commencement date of the business year for which the acquisition date first begins on or after 1 January 2020, and is applied prospectively to all business combinations and asset acquisition transactions.

- Definition of materiality of K-IFRS No.1001 and K-IFRS No.1008 (revision) This amendment is intended to make the materiality defined in SKAS No.1001 easier to understand, and are not intended to change the basic concept of materiality in SKAS. The notion that non-critical information makes sensitive information 'obscure' is included as part of the new definition. The definition of materiality in SKAS No.1008 is replaced with reference to the definition of materiality in SKAS No.1001. In addition, the International Accounting Standards Committee has revised other standards and 'concept frameworks' that include definitions of materiality or reference the term 'materiality', in order to ensure consistency. The Group does not expect the enactments and amendments to have a significant effect on the amounts recognized in the Group's financial statements.

2) The following are the details of the K-IFRS which were enacted and announced as of the date of approval for the financial statements but the effective date has not yet arrived, and the Group has not been applied in advance:

- K-IFRS No.1001 ‘Classification of current and non-current liabilities’ (amendment) This amendment only affects the indication of current and non-current liabilities in the financial statements, and does not affect the amount of assets, liabilities and gains or losses, the time of recognition, or the

dart.fss.or.kr Page 43 disclosure information for those items. This amendment clarify that the classification of current and non-current liabilities is based on the entity's rights that exist at the end of the reporting period, and also highlights that it is irrelevant to expectations of whether the entity will exercise its right to defer settlement of the debt. At the end of the reporting period, if the loan agreement is complied with, the right exists, and settlement is clarified as the transfer of cash, equity instruments, or other assets or services to the counterparty. This amendment is applied retroactively after the commencement date of the first fiscal year starting on or after 1 January 2023, and early application is permitted.

- Reference to SKAS No.1103 'Conceptual System’ (amendment) This amendment includes the content that SKAS No.1103 refers to the 'Conceptual System' (2018) instead of the previous system ('Conceptual System' (2007)). In addition, this amendment also adds a requirement that in the case of provisions or contingent liabilities that fall within the scope of application of SKAS No.1037, the acquirer applies SKAS No.1037 to determine whether a current obligation exists as a result of past events at the acquisition date. In the case of contributions that fall within the scope of application of Interpretation of SKAS No.2121, the acquirer applies interpretation of SKAS No.2121 to determine whether an obligatory event that creates a payment liability for the contribution has occurred by the acquisition date. This amendment adds an explicit statement that the acquirer does not recognize contingent assets in a business combination. This amendment applies to business combinations after the commencement date of the business year for which the acquisition date first begins on or after 1 January 2022. Early application of the amendments is allowed only when all the amendments under the 'Amendments to the Conceptual System References in the K-IFRS' published together with the amendments are applied before or simultaneously with the amendments.

- SKAS No.1016 ‘Tangible assets’ (amendment) This amendment prohibits that the sales amount of goods produced before the tangible assets become usable, the sale of goods produced before it reaches the place and condition necessary to operate in the manner intended by management, is deducted from the cost of the tangible assets. Accordingly, such sales amount and related costs are recognized in profit or loss, and the costs are measured in accordance with SKAS No.1002. In addition, this amendment clarifies the meaning of 'testing whether tangible assets operate normally', and states it for evaluating whether the technical and physical performance of an asset can be used for the production or provision of goods or services, lease to others, or management activities. Unless the goods produced are the output of the entity's ordinary activities and the sales amount and costs included in profit or loss are separately indicated in the statement of comprehensive income, the Company should disclose the amount and cost of the sale, as well as an account in the statement of comprehensive income that includes the amount and cost of the sale. This amendment applies retrospectively only to tangible assets that has reached a location and condition capable of operating in the manner intended by management after the commencement date of the earliest period indicated in the financial statements for which this amendment is first applied. The cumulative effect

dart.fss.or.kr Page 44 of the initial application of this amendment is recognized by adjusting the opening balance of retained earnings (or other components of equity, if appropriate) at the beginning of the earliest indicated period. This amendment will be applied from the first fiscal year beginning on or after 1 January 2022, and early application is permitted.

- Loss-bearing contract and contract execution cost under SKAS No.1037 (amendment) This amendment clarifies that the cost of executing a contract consists of costs directly related to the contract. Costs directly related to a contract consist of the incremental costs (e.g. direct labor cost and direct material cost) to perform the contract and any other cost allocations (e.g. depreciation of tangible assets used in the performance of the contract) directly related to the performance of the contract. This amendment applies to contracts for which all obligations have not been fulfilled on the commencement date of the fiscal year in which this amendment is first applied. The comparative financial statements are not rewritten, but instead, the cumulative effect by the first adoption of the amendments is recognized as retained earnings at the date of initial application or, as appropriate, other elements of equity. This amendment will be first applied to the fiscal year beginning on or after 1 January 2022, and early application is permitted. - Annual improvements of 2018-2020 cycle based on K-IFRS This annual improvement includes some amendments to SKAS No.1101 ‘The first adoption of K-IFRS’, SKAS No.1109 “Financial instruments’, SKAS No.1116 ‘Lease’ and SKAS No.1041 'Agricultural, forestry and fisheries businesses’.

① SKAS No.1101 ‘The first adoption of K-IFRS’

This amendment provides an additional exemption from accounting for cumulative translation differences in subsidiaries that become first adopters later than the controlling company. Subsidiaries subject to the exemption provisions in paragraph D16(1) of SKAS No.1101 may choose to measure the cumulative translation difference of all overseas operations at the carrying amount to be included in the parent's consolidated financial statements on the basis of the date of transition of the controlling company to the K-IFRS. However, the effect of the business combination in which the controlling company acquires a subsidiary and adjustments in accordance with the consolidation procedure are excluded. A similar choice may be made if an associate or joint venture applies the exemption provisions in paragraph D16(1) of SKAS No.1101. This amendment will be applied from the first fiscal year beginning on or after 1 January 2022, and early application is permitted. ② SKAS No.1109 ‘Financial instruments’ This amendment includes only fees received or paid between the entity (borrower) and the lender when applying the '10%' test to assess whether financial liabilities have been removed, which clarifies that it includes fees paid or received by businesses or lenders on behalf of other parties. This amendment will be applied prospectively to changes and exchanges that have occurred after the initial application date. This amendment will be applied from the first fiscal year beginning on or after 1 January 2022, and early application is permitted.

dart.fss.or.kr Page 45 ③ SKAS No.1116 ‘Lease’

This amendment deleted the contents of the lease improvement reimbursement amount in case 13 of SKAS No.11116. Since this amendment is only relevant to applicable cases, the effective date has not been specified separately.

④ SKAS No.1041 ‘Agricultural, forestry and fisheries businesses’ under SKAS No.1041

This amendment deleted the requirement to exclude tax-related cash flows when measuring the fair value of biological assets. This is in line with the requirements of SKAS No.1113 to ensure the use of an internally consistent cash flow and discount rate with the fair value measurement in SKAS No.1041, and the entity can choose whether to use pre-tax or post-tax cash flows and discount rates to determine the most appropriate fair value. This amendment will be applied from the first fiscal year beginning on or after 1 January 2022, and early application is permitted. The Group is reviewing the impact of the enactments and amendments listed above on the financial statements.

3. Significant accounting policies Significant accounting policies applied by the Group to prepare the consolidated financial statements in accordance with the K-IFRS are described below, and the consolidated financial statements of the current and previous years for comparison were prepared by applying the same accounting policies.

(1) Sales division The Group classifies divisions based on internal reporting data, which is periodically reviewed by the chief operating decision maker to make decisions on resources to be allocated to divisions and to evaluate division performance. The Group identifies and reports the sales division as a single division.

(2) Consolidation

① Business combinations Business combinations are accounted for using the acquisition method, except for combinations of entities and businesses under common control. Transfer considerations are generally measured at fair value as the same way that identifiable net assets are measured at fair value. When goodwill is generated as a result of a business combination, impairment tests are conducted annually, and the bargain purchase gain is immediately recognized as net income. Acquisition-related costs are expensed in the period in which they are incurred and provided for services, except for the cost of issuance of debt securities and equity securities, which are recognized in accordance with K-IFRS No.1032 and K-IFRS No.1109. Transfer considerations do not include any amounts related to the settlement of existing relationships. The settlement of existing relationships is generally recognized in profit or loss. Contingent consideration is measured at fair value on the acquisition date. Contingent consideration classified as equity are not remeasured and subsequent settlements are accounted for in equity. When the contingent consideration is not classified as equity, the change in fair value of the conditional consideration

dart.fss.or.kr Page 46 is subsequently recognized in profit or loss. In the case of an acquirer's share-based payment exchanged for compensation held by the acquiree's employees, all or part of the market-based measurement of the acquirer's replacement compensation is included in measurement of the transfer conditions for the business combination. Substitutional remuneration and remuneration for post-combination services, which are part of the consideration transferred to the acquiree, are determined by comparing market-based measurements of the acquiree's remuneration with the amount of replacement compensation for pre-combination services.

② Non-controlling interests Non-controlling interests are measured as the proportionate share of the current equity instruments among recognized amounts of the acquiree's identifiable net assets at the acquisition date. Changes in the parent's ownership interest in subsidiaries that do not lose control are treated as equity transactions.

③ Subsidiaries Subsidiaries are entities controlled by the Group. The Group controls an investee when it is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Subsidiaries' financial statements are included in consolidated financial statements from the date the parent acquires control over the subsidiaries until they lose control.

④ Loss of control If the controlling company loses control of a subsidiary, the Group eliminates assets and liabilities of the previous subsidiary from the consolidated statement of financial position and recognizes gains and losses on control of the control. Remaining investments in subsidiaries are recognized at fair value when control is lost.

⑤ Equity in the investee under equity method The Group's equity interest in the investee under equity method consists of equity interests of associates and joint ventures. Associates are those entities in which the Group has significant influence, but not control or joint control, over financial and operating policies. Joint ventures are entities in which the Group does not have a right to assets or liabilities for contracts, but rather net assets to the contracts. Investments in associates and joint ventures are recognized initially at cost, including transaction costs. After acquisition, they are accounted for using the equity method. In other words, the carrying amount of the investee's profit or loss and other comprehensive income after the acquisition date is added to or subtracted from the carrying amount. The distribution received from the investee is deducted from the carrying amount.

⑥ Elimination of internal transactions Transactions in the Group, related balances, income and expenses, and unrealized gains and losses are all eliminated during the preparation of the consolidated financial statements. On the other hand, the Group removes the unrealized gains from unrealized gains from transactions with the investee with equity method. Unrealized losses are eliminated in the same manner as unrealized gains unless there is evidence of impairment.

dart.fss.or.kr Page 47 ⑦ Business combinations under the same control In the case of a combination of an entity or business under the same control, acquired assets and liabilities are recognized as the carrying amount in the consolidated financial statements of the highest controlling company. The difference between the consideration transferred and the carrying amount of net assets acquired is added or subtracted from the capital surplus.

(3) Cash and cash equivalents The Group is classifying investments with cash and cash equivalents with maturities of three months or less after the acquisition date. Equity securities are excluded from cash and cash equivalents, but are included in it if the equity securities are practical cash and cash equivalents just like preferred shares, which have a designated redemption date as well as a short-term period from the date of acquisition to redemption date.

(4) Inventories The unit cost of inventories is determined by the moving average method, and the cost of acquisition includes acquisition costs, conversion costs and other costs necessary to prepare the inventory for use. Inventories are stated at the lower amount between cost or net realizable value. The valuation losses and net loss on the reduction of inventories to net realizable value are recognized as expenses in the period in which the reduction or loss occurs, and reversal of the loss on the valuation of inventories caused by the increase in net realizable value of the inventory is reversed. It is deducted from the cost of sales of the inventory recognized as an expense in the period in which it occurred.

(5) Non-derivative financial assets

① Recognition and initial measurement Trade receivables and issued debt securities are recognized for the first time when they are issued. Other financial instruments and financial liabilities are recognized only when the Group becomes a contracting party for financial instruments. Except for trade receivables that do not include any significant financial elements, financial assets or liabilities are measured at fair value at the date of initial recognition, and are not measured at fair value through profit or loss or financial assets at FVTPL. In such cases, transaction costs that are directly attributable to the acquisition of the financial asset or the issue of that financial liability are added to or deducted from the fair value. Trade receivables that do not contain significant financial factors are initially measured at the transaction price.

② Classification and follow-up measurement At initial recognition, financial assets are classified to be measured at amortized cost, debt instruments at FVTOCI, equity instruments at FVTOCI, or financial assets at FVTPL. Financial assets are not reclassified after initial recognition unless the Group changes the business model that manages them. In this case, all affected financial assets are reclassified on the first day of the first reporting period after the business model is changed.

dart.fss.or.kr Page 48 When a financial asset meets both conditions specified below and is not designated as at FVTPL, the asset is measured at amortized cost. - Debt instruments that are held within a business model with the objective of collecting the contractual cash flows. - In accordance with the terms of the financial asset contract, cash flows consisting only of interest payments on the principal and the balance of the principal are generated on a specific date. When the debt instrument meets both conditions specified below and is not designated as at FVTPL, the asset is measured at FVTPL. - Debt instruments that are held within a business model with the objective achieved both by collecting contractual cash flows and selling financial assets - In accordance with the terms of the financial asset contract, cash flows consisting only of interest payments on the principal and the balance of the principal are generated on a specific date. Upon initial recognition of an equity instrument that is not held for trading, the Group may choose to present, in other comprehensive income, the subsequent change in the fair value of the investment. However, the designation is irrevocable. These designations are made on a per-investment basis. All financial assets that are not measured at fair value through amortized cost or other comprehensive income described above are measured at FVTOCI. These financial assets include all derivative financial assets. If a financial asset carried at amortized cost or FVTOCI at initial recognition is designated as at FVTPL and the accounting inconsistency is eliminated or significantly reduced, the Group may designate the financial asset as to be measured at FVTPL. However, the designation is irrevocable.

1) Business model The Group evaluates the way business is being managed, and the purpose of the business model for managing a financial asset best reflects the way information is provided to the management at its portfolio level. Such information takes the followings into account: - The accounting policies and purpose specified for the portfolio, the actual operation of such policies. This includes management's strategy of obtaining or realizing expected cash flows through the acquisition of contractual interest income, maintenance of interest return at a certain level, and the matching of the duration of the liability that procures financial assets and the duration of the financial assets. - The way the performance of a financial asset held under the business model is evaluated, and the way such evaluation is being reported to the management - The risk affecting the performance of the business model (and financial assets held under the business model), and the way such risk is being managed - The compensation plan for the management (e.g. whether the management is being compensated based on the fair value of assets or based on the received contractual cash flows) - Frequency, amount, timing and reason for sale of financial assets in the past, and forecast of future sale activities. For these purposes, a transaction that transfers a financial asset to a third party is not considered to be sold if the transaction does not meet the elimination requirement. A portfolio of financial assets that meets the definition of short-term trading or whose performance is evaluated at fair value is measured at FVTPL.

2) Valuation of whether the contractual cash flow consists solely of principal and interest

dart.fss.or.kr Page 49 The principal is defined to be the fair value of a financial assets at initial recognition. Interest does not only consist of consideration for the time value of money, consideration for the credit risk related to remaining principal at a certain period of time, consideration for other cost (e.g. liquidity risk and cost of operation) and fundamental risk associated with lending, but also profit. When evaluating whether contractual cash flows are solely payments of principal and interests, the Group considers the contractual terms of the financial instrument. When a financial asset contains contractual conditions that modify the timing and amount of contractual cash flows, it is required to determine whether contractual cash flows, which arise during the remaining life of the financial instrument due to such contractual condition, are solely payments of principal and interest. The Group considers the followings when evaluating the above-mentioned items: - Conditional situations that change the amount or timing of cash flows - Provisions for adjusting the par value interest rate under the contract, including variable rate characteristics - Intermediate repayment characteristics and maturity extension characteristics - Contractual terms that limit the Group’s claim on cash flows arising from certain asset If the prepayment amount represents the interest on the unpaid principal and the remaining principal, and includes additional reasonable compensation for the early settlement of the contract, the early repayment characteristics are consistent with the conditions for paying principal and interest on a specific date. Also, for financial assets acquired by significant discounts or premiums on contractual par value, the intermediate repayment amount substantially represents the contractual par value and contractual interest accruals (but not paid) (in this case, upon early settlement of the contract). If the fair value of the characteristic is minor at the time of initial recognition, it is determined that the condition is satisfied.

③ Follow-up measurement and profit or loss

1) Financial assets at FVTPL These assets are subsequently valued at fair value. Net gain or loss including interest or dividend income is recognized in profit or loss.

2) Financial assets measured at amortized cost They are subsequently measured at amortized cost using the effective interest method. Amortized cost is reduced by impairment loss. Interest income, gain or loss on foreign currency translation and impairment loss are recognized in profit or loss. Gains or losses arising from removals are recognized in net income.

3) Debt instruments at FVTOCI These assets are subsequently valued at fair value. Interest income is calculated using the effective interest method, and foreign currency translation gains/losses as well as impairment loss are recognized in profit or loss. Other net gains and losses shall be recognized in other comprehensive income. Gains or losses on disposal are reclassified into profit or loss from other comprehensive income.

4) Equity instruments at FVOCI These assets are subsequently valued at fair value. Dividends are recognized in net income unless they expressly recover the investment. Other net income is recognized in other comprehensive income and will not be reclassified into profit or loss.

dart.fss.or.kr Page 50 ④ Removal of financial assets When the contractual right related to cash flows of a financial asset expires, the Group transfers the contractual right to receive the cash flows of the financial asset, and substantially transfers most of the risks and rewards of ownership of the transferred financial asset., or removes financial assets if the Group does not control its financial assets, and does not retain or transfer most of its risks and rewards. The Group does not remove a transferred asset if the Company has made a transaction that transfers the assets recognized in the statement of financial position, but holds most of the risks and rewards of ownership of the transferred asset.

⑤ Offset of financial assets The Group offsets financial assets with financial liabilities and indicates them in the consolidated financial statements on a net basis only if it currently has a legally enforceable offset right for both the financial assets and financial liabilities being recognized, and intends to make their repayment with the differences or to repay the liabilities as soon as possible to realize the assets.

⑥ Impairment of financial assets

1) The Group recognizes loss allowance for expected credit losses on the following assets. - Financial assets measured at amortized cost - Other debt instruments measured at FVTOCI - Lease receivables Provisions for losses on trade receivables and other receivables measured at amortized cost are always measured at an amount equal to the expected credit loss for the entire period. When determining whether the credit risk of a financial asset has increased significantly since the initial recognition, and when estimating expected credit losses, the Group considers available, reasonable, and supportable information without the need of using excessive cost or effort. This includes qualitative and quantitative information and analysis based on our past experience and known credit ratings, including forward-looking information. Expected credit loss for the entire period is expected credit loss for all potential defaults for the expected life of a financial instrument. The longest period the Group consider when measuring expected credit loss is the longest contract period in which we are exposed to credit risk.

2) Measuring expected credit losses The expected credit loss is the probability weight of the credit loss. Credit loss is measured as the present value of all cash deficits (e.g. the difference between all contractual cash flows that are expected to be paid under the contract, and all contractual cash flows that are expected to be received). The expected credit loss is discounted at the effective interest rate of the financial asset.

3) Financial assets with damaged credit At the end of each reporting period, the Company assesses whether credits of the financial assets measured at amortized cost are impaired. The financial asset is impaired if one or more events have occurred, which adversely affect the estimated future cash flows of a financial asset.

dart.fss.or.kr Page 51 Evidence of credit-impaired financial assets includes the following observable information: - Significant financial difficulties of the issuer or borrower

4) Indication of allowance for credit loss on the consolidated financial statements Loss allowances for financial assets and lease payment receivables measured at amortized cost are deducted from the carrying amount of those assets.

5) Disengagement If there is no reasonable expectation for the recovery of all or part of the contractual cash flows of the financial assets, the asset is removed. The Group evaluates the timing and cost of each break by assessing whether the corporate customer has reasonable expectations for recovery. The Group does not expect the eliminated amount to be recovered significantly. However, each eliminated financial assets may be subject to recovery activities in accordance with the recovery process for the mature amount of the Group.

(6) Tangible assets Tangible assets are initially recognized to be measured at cost. The cost of tangible assets includes costs that are directly attributable to the management's intentional method of bringing the asset to its place and condition, and what is estimated to be incurred in the decommissioning, removal, or restoration of the property. After initial recognition, the carrying amount of the tangible assets are recognized as the cost subtracted by depreciation addition amount and accumulated depreciation. Costs incurred when a part of a tangible asset is replaced are included in the asset's carrying amount, if it is probable that future economic benefits arising from the asset will flow into the Group and the cost can be measured reliably. Where appropriate, it is recognized as a separate asset. At this time, the carrying amount of the replaced portion is not recognized. Other costs incurred in connection with routine repairs and maintenance are recognized in profit or loss as incurred. Land is not depreciated among tangible assets, and other tangible assets are amortized using the straight- line method, which best reflects the expected consumption pattern of inherent future economic benefits in the asset over its useful life. If the cost of a part of the tangible assets is significant in relation to the total cost of the tangible assets, the part is depreciated separately. The gain or loss arising from the removal of the tangible assets is determined by the difference between the net sale and the carrying amount, and the difference is recognized in other profits or expenses. The following are the estimated useful lives of tangible assets for the current and last years: Division Durable years Buildings and structures 20, 40 years Machinery 5 years Equipment 4 years Other tangible assets 2 to 5 years At the end of each reporting period, the Group reviews residual value of assets, useful life and depreciation method, and if it is determined to be appropriate to change these, the Group treats it as a change of the accounting estimate.

dart.fss.or.kr Page 52 (7) Intangible assets At the initial recognition, intangible assets are measured as costs, and the accumulated depreciation after deducting accumulated impairment losses is recorded as the carrying amount. Intangible assets are amortized using the straight-line method with zero (“0”) residual value over their estimated useful lives as of the date of their availability. However, for some intangible assets, since there is no foreseeable limit on the period in which this method is available to use, the useful life of such intangible assets is deemed as indefinite and not amortized.

dart.fss.or.kr Page 53 The estimated useful lives of intangible assets for the current and last years are as follows: Division Durable years Goodwill Indefinite Industrial property rights 10 years Software 5 years Membership Indefinite Other intangible assets 5 years Amortization period and amortization method for finite intangible assets are reviewed at the end of each reporting period. Intangible assets with indefinite useful lives are reviewed at the end of each reporting period, in order to determine whether the assessment of their useful life as indefinite. If it is deemed appropriate to change this, it is treated as a change in the accounting estimate. The subsequent expenditures are capitalized only if the future economic benefits of the related asset are increased. Other expenses, including internally generated goodwill and trade names, are immediately expensed.

(8) Goodwill The goodwill corresponds to the consideration paid for the amount paid more than the fair value regarding net identifiable assets acquired at the time of the business combination, and it is counted as intangible assets. Although goodwill is not amortized, it is tested for impairment every year and displayed as a cost calculated by deducting accumulated impairment loss from the principal amount.

(9) Government subsidies Government subsidies are recognized only if the Company have reasonable assurance that the Company will comply with the conditions attached to it.

① Asset-related subsidies The Group receives government subsidy with a necessary basic standard that the subsidy should be used for acquiring or building intangible assets. When calculating the asset’s carrying amount, the subsidy is deducted, and it is recognized as profits or losses over the useful life of the depreciable assets.

② Income-related government subsidies The Group recognizes the income-related government subsidies as the profit or loss of the current year using a method of deducting it from relevant cost, throughout the period of recognizing the cost as relevant cost that intends to be preserved as the government subsidies.

(10) Damage of nonfinancial assets For all non-financial assets except for the assets arising from employee benefits, inventories, deferred tax assets and non-current assets held for sale, we review whether there are indications that the asset is impaired and, if so, we estimate the recoverable amount of the asset. However, we test impairment annually by comparing the recoverable amount with the carrying amount regardless of the indication of impairment for intangible assets with indefinite useful lives and intangible assets that are not yet available. Recoverable amount is estimated for each asset, or if the recoverable amount of an individual asset cannot be estimated, it is estimated for each cash generating unit to which the asset belongs to. Recoverable amount

dart.fss.or.kr Page 54 is decided as the higher amount between the pure fair value or value in use. The value in use is discounted by discounting future cash flows expected to be generated from the asset, or cash-generating unit at an appropriate discount rate that reflects the current market's assessment of the specific risks of the asset (which have not been adjusted in estimating the time value of the money and future cash flows). If the recoverable amount of an asset or cash generating unit is less than its carrying amount, the carrying amount of the asset is reduced and immediately recognized in profit or loss. At the end of each reporting period, the Company reviews for assets excluding goodwill that there are indications that the impairment loss recognized in the past does notexist anymore or has been reduced. Subsequently, reversal is made only if there is a change in the estimate used to determine recoverable amount from the date of the impairment loss. The carrying amount increased by reversal of an impairment loss cannot exceed the depreciation or amortization of the carrying amount prior to the impairment loss being recognized in the past. Goodwill acquired in a business combination is allocated to each cash-generating unit that is expected to benefit from the synergies of the business combination. Impairment losses on cash-generating units reduce the carrying amount of goodwill allocated to the cash-generating unit first, and then reduce the carrying amount of the asset in proportion to the carrying amount of each of the other assets in the cash-generating unit. The impairment losses recognized for goodwill cannot be reversed later. At the end of each reporting period, the Company reviews for assets excluding goodwill that there are indications that the impairment loss recognized in the past does not exist anymore or has been reduced. Subsequently, reversal is made only if there is a change in the estimate used to determine recoverable amount from the date of the impairment loss. The carrying amount increased by reversal of an impairment loss cannot exceed the depreciation or amortization of the carrying amount prior to the impairment loss being recognized in the past.

(11) Lease

1) In a case where the Group is a lessee On the date of entering into the contract, the Group identifies whether the contract is a lease or includes a lease. In the case of a lessee, the Group recognizes right-of-use assets and corresponding lease liabilities for all lease arrangements, excluding short-term leases (less than 12 months) and leases on small underlying assets. The Group recognizes lease payments related to short-term leases and leases on small underlying assets as a straight-line expense over the lease term, unless other systematic criteria describe the form of the lessee's benefits in a better way. Lease liabilities are initially measured at the lease commencement date at the present value of the unpaid lease payments as of that day, discounted at the lease's intrinsic interest rate. If the lease's intrinsic interest rate cannot be calculated easily, the lessee's incremental borrowing rate is used. The lease payments included in the lease liability measurement consist of the followings: - Fixed lease (including substantial fixed lease payments and deducting any lease incentives to be received) - Fluctuating lease rates that depend on the index or rate (interest rate). Initially measured using an index or rate (interest rate) on the starting day of lease. - Amount expected to be paid in accordance with the residual value guarantee - The exercise price of the purchase option when it is fairly certain that the lessee will exercise the purchase option. - The amount borne to terminate the lease when the lease term reflects the lessee's exercise of the

dart.fss.or.kr Page 55 option to terminate. The Group presents leased liabilities separately from other liabilities in the financial statements. Lease liabilities are measured by subsequently increasing (using the effective interest method) the carrying amount by reflecting interest on the lease liabilities, and decreasing the carrying amount by reflecting the paid lease payments. The Group remeasures the lease liabilities and makes a corresponding adjustment to the related right to use assets in the following cases. - When the lease period is changed or a change in circumstances or a significant event occurs that causes a change in the evaluation of the exercise of the purchase option. In this case, the lease liabilities are re-measured by discounting the revised lease payments at the revised discount rate. - When the lease fee changes due to a change in the index or rate (interest rate) or due to a change in the amount expected to be paid in accordance with the residual value guarantee, the lease liabilities are remeasured by discounting the revised lease payments at the unchanged discount rate. However, if there is a change in the lease due to a change in the variable interest rate, a modified discount rate will be used, which reflects the change in the interest rate. - When the lease contract is changed and it is not accounted for as a separate lease, the lease liability is remeasured by discounting the revised lease payments at the revised discount rate as of the effective date of the lease change based on the lease term of the revised lease. Licensed assets consist of the initial measurement of the lease liabilities, the lease payments paid on or before the lease commencement date (deducting lease incentives received), and the lease opening direct costs borne by the lessee. Licensed assets are measured subsequently by deducting accumulated depreciation and accumulated impairment losses from cost. The estimates of the costs incurred by the Group when dismantling and removing the underlying asset, restoring the premises on which the underlying asset is located, or restoring the underlying asset itself are recognized and measured in accordance with SKAS No.1037 as required by the terms of the lease. If such costs are not incurred to produce inventory, the cost of the licensed asset is recognized as part of the cost of the licensed assets when the cost is related to the licensed assets. If ownership of the underlying asset is transferred to the lessee prior to the end of the lease term, or if the cost of the licensed assets reflects that the lessee will exercise the purchase option, the lessee depreciates the licensed assets from the lease commencement date to the end of the useful life of the licensed assets. In other cases, the lessee depreciates the licensed assets from the lease commencement date to the end of the useful life of the licensed assets or the end of the lease term, whichever is earlier. The Group presents licensed assets separately from other assets in the financial statements. The Group applies SKAS No.1036 to determine whether the licensed assets are impaired, and accounting for the identified impairment loss is described in the accounting policy of 'Tangible assets' (Note 3.(6)). The Group does not include variable lease payments (excluding variable lease fees that vary depending on the index or rate (interest rate)) in the measurement of licensed assets and lease liabilities, and such lease payments are recognized in profit or loss during the period in which the event or condition occurs where the variable lease payment occurs. As a practical and simple method, the lessee can choose the method of accounting for each leased element and related non-lease elements as a single leased element, not separating the non-lease element from the leased element, for each type of underlying asset. However, the Group is currently not using the practical and simple method. In a contract that contains one leased element and one or more additional leased or

dart.fss.or.kr Page 56 non-lease elements, the lessee allocates the contract consideration to each leased element, based on the relative individual price of the leased element and the total individual price of the non-lease element.

2) In a case where the Group is a lease provider The Group classifies each lease as an operating lease or a finance lease. Leases that transfer most of the risks and rewards of owning the underlying asset are classified as financial leases, and leases that do not transfer most of the risks and rewards of owning the underlying asset are classified as operating leases. When the Group is an intermediate lease provider, the Group accounts for the upper lease and the sublease lease as two separate contracts. The Group classifies sublease leases as financial leases or operating leases based on the licensed assets arising from higher leases rather than underlying assets. The Group recognizes lease payments from operating leases on a straight-line or other systematic basis. If other systematic criteria represent a form of diminishing returns from the use of the underlying asset in a better way, the Group applies those criteria. The Group adds the direct cost of opening a lease in the process of concluding an operating lease to the carrying amount of the underlying asset, and recognizes it as an expense over the lease term on the same basis as lease income. In finance leases, the amount received from the lessee is recognized as receivables as net investment on the lease. The Group distributes financial income over the lease term in a way that reflects a certain periodic rate of return to the Group's net investment on leases. After initial recognition, the Group regularly reviews the estimated non-guaranteed residual value, and recognizes the expected credit loss on lease receivables as a provision for loss, by applying the requirements for derecognition and impairment specified in SKAS No.1109. Finance lease income is calculated by referring to the total carrying amount of lease receivables. However, for financial lease receivables with impaired credit, financial income is calculated by referring to amortized cost (i.e., the amount after deducting allowance for losses from it). If the contract includes lease and non-lease elements, the Group allocates the contract consideration to each component using SKAS No.1115.

(12) Non-derivative financial liabilities The Group classifies financial liabilities into financial liabilities and other financial liabilities in accordance with the contents of the contract and definition of financial liabilities, and recognizes them in the financial statementsas part of the contract.

① Financial liabilities recognized in the current profit or loss Financial liabilities at FVTPL include short-term trading financial liabilities or financial liabilities designated as financial liabilities at FVTPL upon initial recognition. Financial liabilities at FVTPL are measured at fair value after initial recognition, and changes therein are recognized in profit or loss. On the other hand, transaction expenses incurred in connection with the issuance of financial liabilities at FVTPL at the time of initial recognition are recognized in profit or loss as soon as they are incurred.

② Other financial liabilities Non-derivative financial liabilities that are not classified as financial liabilities at fair value through profit or loss are classified as other financial liabilities. At the initial recognition, other financial liabilities are measured at the amount deducted by transaction cost directly related to issue at fair value. Subsequently,

dart.fss.or.kr Page 57 other financial liabilities are measured at amortized cost through the application of the effective interest method, and the associated interest cost is recognized. Financial liabilities are derecognized from the financial statements only when they cease to exist. That is, when the contractual obligation is fulfilled, canceled or expired.

(13) Employee benefits

① Short-term employee benefits Short-term employee benefits, which will be settled within 12 months from the end of the reporting period when an employee provides related service, are recognized in profit or loss once the service is provided. Short-term employee benefits are measured at undiscounted amount.

② Other long-term employee benefits For other long-term employee benefits that are not to be paid within 12 months from the end of the reporting period, in which the employee provided related service services, future benefits earned in exchange for the service provided in the current and past periods are discounted to the present value. Changes from remeasurement are recognized in profit or loss in the period in which they arise.

③ Pensions: Defined benefit plan As of the end of the reporting period, defined benefit obligations related to defined benefit plans are recognized by deducting the fair value of plan assets from the present value of the defined benefit obligation. The defined benefit liability is calculated annually by an independent actuary, using the projected unit credit method. In a case where the net amount calculated by subtracting the fair value of plan assets from the present value of defined benefit obligations is an asset, the asset is recognized only to the extent of its present value of available annual benefits, either in the form of a refund from the plan or a reduction in future contributions to the plan. The remeasurement component of net defined benefit liabilities is a change in the upper limit on recognition of assets, except for actuarial gains and losses, net interest on net defined benefit liabilities, and net interest on defined benefit liabilities. It is immediately recognized in other comprehensive income. The Group's net interest in the defined benefit liabilities (assets) is determined by multiplying the net defined benefit liabilities (assets) by the discount rate, which is determined at the beginning of the annual reporting period. During in consideration of changes in net defined benefit liabilities (assets) due to contributions and payments. Net interest expense and other expenses related to the defined benefit plan are recognized in profit or loss. In the event of a plan amendment or reduction, gains or losses resulting from changes or reductions in benefits for past work are immediately recognized in profit or loss. The Group recognizes gains or losses on the settlement of a defined benefit plan when the cumulative settlement occurs.

(14) Estimated liabilities Estimated liabilities are present (legal or statutory) obligation that exists as a result of a past event, and it is recognized that resources with economic benefits are likely to be leaked in order to fulfill the obligation, and the amount required to fulfill the obligation can be estimated reliably. The amount recognized as estimated liabilities is the optimum estimate of the expenditures required to carry out the present obligation at the end of the reporting period, taking into account the inevitable risks and

dart.fss.or.kr Page 58 uncertainties associated with the events and circumstances. If the time value effect of money is significant, the estimated liabilities are valued at the present value of the expenditures expected to settle the obligation. When it is expected that a third party will reimburse some or all of the expenditure required to settle the estimated liabilities, the Company recognizes the reimbursement amount and accounts for it as a separate asset only when it is almost certain that the entity will be reimbursed. The balance of the estimated liabilities is reviewed at the end of each reporting period and adjusted to reflect the best estimate as of the reporting date. If it is no longer highly possible that the outflow will occur to resources in which economic benefits are embedded for the performance of the obligation, the related estimated liabilities are reversed. Estimated liabilities for sales guarantees is recognized when a product or service is sold or provided, and is estimated by weighting average of all possible outcomes and associated probabilities based on past guarantee data. Estimated liabilities are used only for expenditures related to initial recognition.

(15) Foreign currency transaction In the preparation of the consolidated financial statement, transactions in currencies other than functional currencies are recorded at the exchange rate on the trading day. At the end of each reporting period, foreign currency monetary items are translated at the closing rate at the end of the reporting period. Non-monetary foreign currency items measured at fair value are converted at the exchange rate at the date when the fair value is determined, and non-monetary items measured at historical cost are converted at the exchange rate at the transaction date. The foreign exchange differences generated at the time of monetary item's payment and those arising from the conversion of monetary items are recognized as profit or loss's other non-operating income and other non-operating expenses category when they are related to business activities. If the differences are related to non-operating activities, then they are recognized as profit or loss' financial income and financial expense items. When gains or losses on non-monetary items are recognized in other comprehensive income, the effect of foreign exchange fluctuations included in the gain or loss is recognized in other comprehensive income, and any gains or losses are recognized in profit or loss.

(16) Paid-in capital Common stock is classified as equity, and incremental costs directly attributable to equity transactions are deducted from equity as a tax effects-reflected net amount. If the Group reacquires its own equity instruments, such instruments are directly deducted from the capital as reacquired shares. The gain or loss is not recognized in profit or loss when the entity purchases, sells, issues or incinerates its equity instruments. When the Group acquires and retains treasury stock, the consideration paid or received is directly recognized in equity.

(17) Revenue from contracts with customers As of 1 January 2018, the Group first applies SKAS No.1115 to all types of contracts by applying a five- step revenue recognition model (① identifying contracts → ② identifying performance obligations → ③

dart.fss.or.kr Page 59 identifying transaction price → ④ allocating transaction prices to performance obligations → ⑤ recognizing revenue during the fulfillment of performance obligations).

① Contract identification The Group identifies the contract with customer when it meets all of the following criteria: - The parties of contract approve the contract and commit to perform their respective obligations. - The rights of each party relating to the goods or services to be transferred can be identified. - The payment terms of the goods or services to be transferred can be identified. - There is a commercial practicality in the contract. - There is a high possibility of collecting the consideration entitled to be received from customer for the goods or services to be transferred. The Group identifies a supply and service contract that meets all of the above criteria as a contract with customer.

② Performance obligations identification At contract inception, the Group reviews the promised goods or services in the contract with the customer to identify the promise to transfer either of the following to the customer as a performance obligation: - A distinguishable good or service (or a bundle of goods or services) - A series of distinguishable goods or services that are substantially the same and have the same transfer method to the customer The performance obligation of the consolidated group identified in the contract with the customer is the provision of the promised product and service.

③ Transaction price calculation The Group refers to the terms of the contract and the business practices of the Company to determine the transaction price. The transaction price is the amount that the entity expects to receive in return of the transfer of promised goods or services to customer, and it excludes the amount collected on behalf of a third party. The Group calculates the transaction price as the consideration received from customer for supply and service of the product. However, the consideration received from customer may change because the Group allows returning of products as stated in the contract for product supply. The Group estimates the variable consideration using an expected value method that it expects to better predict the consideration to be entitled to. In addition, the Group recognizes revenue by including the variable consideration in the transaction price only to an amount which is highly probable that it will not reverse a significant portion of the cumulative revenue already recognized at the time of expiration of the return period. The amount of consideration received or to be received by the Group, to which the Group is not expected to be entitled to, shall be counted as a refund liability and recognized as a new asset for the recovery right for the returned asset.

④ Allocating transaction price to performance obligation The Group assigns the transaction price to each performance obligation in an amount indicating the right to receive payments in return of the transfer of promised goods or services to customer.

dart.fss.or.kr Page 60 In the contract with the customer, the Group's performance obligation is provision of products and services, which consists of a single performance obligation for the identified distinguishable goods and services. Thus, the transaction price is not allocated.

⑤ Recognition of revenue during the fulfillment of performance obligations The Group satisfies its performance obligation by transferring promised goods or services to the customer, and recognizes transaction price allocated to performance obligation as revenue when the customer controls goods or services. The Group recognizes revenue by viewing the performance obligation of supplying products and providing services as being satisfied at a point in time. In particular, as for service provision, the Group shall recognize revenue as a performance obligation satisfied from the time when the assets created by the Group's performance do not have an alternative use to the entity itself. In addition, it shall be deemed to be satisfied if the performance completed to date does not meet the requirements of the performance obligation that requires performance to be carried out over a period during which payment claim is enforceable.

(18) Financial revenues and financial costs Financial earnings include interest income, converted profit and foreign exchange gains on foreign currency financial instruments, and net profit on financial assets measured at FVTPL. Interest income is recognized in profit or loss using the effective interest method over the period. Financial expenses include interest costs on borrowings, and converted loss and foreign exchange loss on foreign currency financial instruments and net profit on financial assets measured at FVTPL. Interest expense on borrowings is recognized in profit or loss using the effective interest rate method. The effective interest method accurately matches the future cash payment estimated during the expected duration of the financial instrument or the current value of the received amount with the total carrying amount of the financial asset or the amortized cost of the financial liability. When calculating the interest income or interest expenses, the effective interest is applied to the total carrying amount of the assets (if the credit of the asset is undamaged) or to the amortized cost of the liabilities. However, for financial assets that have subsequently been credit-impaired since initial recognition, interest income is calculated by applying the effective interest rate to the amortized cost of the financial asset. If the asset is no longer considered as credit-impaired, the interest income shall be calculated by applying the effective interest rate to the total carrying amount.

(19) Income tax Income tax expense consists of current and deferred taxes and is recognized in profit or loss, except to the extent that it is recognized in other comprehensive income or directly in equity or in transactions or events.

① Current income tax Current income tax is calculated based on taxable income for the year. Taxable income differs from profit or loss in the consolidated statement of income because it excludes profit or loss, tax exempt items and non-taxable items that are added to or deducted from other taxable income in the statement. Accrued income taxes payable related to the Group's current income tax are calculated using enacted or substantively enacted tax rates.

② Deferred income tax

dart.fss.or.kr Page 61 When measuring the deferred tax liabilities and the deferred tax assets, the Group reflects the tax effects based on the expected method of collecting or paying the carrying amount of the assets or liabilities at the end of the reporting period. For the temporary differences to add for subsidiaries, associates and joint venture investment equity, the Group can control the extinction time point of the temporary differences, and deferred tax liabilities are recognized for all cases except where there is a high possibility that the temporary differences would not be extinct within the predictable future. Also, deferred tax assets that arise due to temporary differences to deduct are recognized in cases where there is a high possibility that the temporary differences will be extinct in predictable future, and that taxable income for which the temporary differences can be used will occur. The carrying amount of a deferred income tax asset is reviewed at the end of each reporting period. The carrying amount of the deferred income tax asset is reduced when it is no longer probable that sufficient taxable profit will be available against which the deductible temporary difference can be utilized. Deferred tax assets and liabilities are measured using tax rates that are expected to apply to the period that the asset is realized or the liability is settled, based on tax legislation enacted or substantively enacted at the end of the reporting period. Deferred tax assets and liabilities are the income tax levied by the same tax office and are offset only when the Group has the right to offset the recognized amounts, and is willing to pay the net amount of the income tax liabilities and assets for the current year. If there exists income tax amount that occurs additionally from dividend payment, it is recognized at the time point when the dividend payment-related liabilities are recognized.

(20) Earnings per share The Group calculates basic and diluted earnings per common share for the year and net profit for the period, and presents it in the consolidated income statement. Basic earnings per share is calculated by dividing the net profit or loss of controlling shareholder for the common shares by the weighted average common shares of the common shares circulated during the reporting period. Diluted EPS is calculated by adjusting the profit or loss and the weighted average number of common shares attributable to common stock to reflect the effect of dilutive potential ordinary shares, such as share-based compensation granted to employees.

(21) Business combinations Business combinations are accounted for using the acquisition method, except for combinations of entities and businesses under common control. Transfer considerations are generally measured at fair value as the same way that identifiable net assets are measured at fair value. When goodwill is generated as a result of a business combination, impairment tests are conducted annually, and the excess is recognized immediately in net income as a bargain purchase gain. Acquisition-related costs are expensed in the period in which they are incurred and provided for services, except for the cost of issuance of debt securities and equity securities, which are recognized in accordance with K-IFRS No.1032 and K-IFRS No.1109. Transfer considerations do not include any amounts related to the settlement of existing relationships. The settlement of existing relationships is generally recognized in profit or loss. Contingent consideration is measured at fair value on the acquisition date, and those classified as equity are not remeasured, and subsequent settlements are accounted for in equity. When the contingent consideration is not classified as equity, the change in fair value of the conditional consideration is recognized in profit or loss subsequently.

dart.fss.or.kr Page 62 4. Important judgment and the major source of estimated uncertainty In applying our accounting policies described in Note 3, management should make decisions (except for matters pertaining to the estimates) that have a significant effect on the amounts recognized in the consolidated financial statements, and make estimates and assumptions about the carrying amount of assets and liabilities that cannot be easily identified from other sources. The estimates and relevant assumptions are based on past experiences and other factors deemed relevant. Moreover, actual results may differ from these estimates. Estimates and basic assumptions are reviewed continuously. Amendments to accounting estimates are recognized in the period in which the amendment is made, if the amendment affects only that period, in the period in which the amendment was made and, and if it affects both the current and future periods.

(1) Management's judgment The following notes include information on key management judgments related to the application of accounting policies, which have a significant effect on the amounts recognized in the consolidated financial statements: - Note 3: Significant accounting policies

(2) Uncertainty of assumptions and estimates The following notes include information about uncertainties in the assumptions and estimates, which have significant risk of material adjustment within the next reporting period: - Note 13: Inventory - assumption on inventory valuation allowance setting - Note 18: Lease liability - judgment on lease duration - Note 20: Estimated liabilities - Assumptions about the likelihood and amount of outflow of resources - Note 32: Measurement of defined benefit obligation - Main actuarial assumptions

(3) Fair value measurement As the accounting policy and disclosure of the Group require the measurement of fair value for many financial and non-financial assets and liabilities, the Group established the policies and procedures for the evaluation of fair value. The policies and procedures include the operations of the evaluation department responsible for the review on the measurement of every significance fair value, which includes fair value classified as Level 3 in the hierarchy system of fair value, and the results are directly reported to the financial executive. The evaluation department is regularly reviewing significant input variables and evaluation adjustment which cannot be observed. If any third party information, such as the broker price or evaluation organization, is used in fair value measurement, the evaluation based on information acquired by the evaluation department from the third party includes the classification per level in the hierarchy system of fair value, and we are making a decision on whether or not to conclude if requirement in the applicable standard are met. If the fair value of an asset or liability is measured, the Group uses the input variable which can be observed from the market as much as possible. The fair values are classified within the hierarchy system of fair values based on input variables used in the valuation techniques as below: - Level 1: Publicly announced price not adjusted in the active market, which is accessible to the same

dart.fss.or.kr Page 63 asset or liability on the measured day - Level 2: Input variable on the asset or liability other than publicly announced price which can be observed directly or indirectly - Level 3: Input variable on the asset or liability which cannot be observed If many input variables used for measuring the fair value of an asset or liability are classified into different levels within the hierarchy system of fair values, the Group classifies the entire fair value measurements into the same level with the lowest level of an input variable in the hierarchy system of significant fair values. In addition, at the end of the reporting period when the variation occurred, the Group recognizes the transfer between levels in the hierarchy system of fair values. Detailed information on the assumptions used in measuring fair value is included in the comments below: - Note 7: Financial risk management

5. Sales division The Group consists of a single research and development organization, while applying the same marketing strategy. It also identifies the sales division as a single division and provides reporting on such a basis. There are two companies whose sales from a single external customer account for more than 10% of the Group's sales, and sales for the current and last years are 861,761 million won (712,570 million won in the previous year) and 143,322 million won (86,154 million won in the previous year), respectively.

dart.fss.or.kr Page 65 (2) Financial incomes and costs by financial instrument category Details of financial incomes and financing costs recognized in the current profit or loss in the current and last years are as follows; (Unit: KRW) Interest revenue (costs) Other income (*) Division Current year Last year Current year Last year Financial liabilities at FVTPL - - (107,886,362) (139,919,764) Financial assets at FVTOCI - - (8,524,015,184) - Financial assets measured at amortized 2,594,003,650 3,822,068,929 1,568,032,952 21,234,005 cost Lease receivables 124,192,931 59,986,441 - - Financial liabilities measured at - - 2,838,403,354 (71,923,722) amortized cost Lease liabilities (216,065,535) (251,687,433) - - Total 2,502,131,046 3,630,367,937 (4,225,465,240) (190,609,481) (*) Other gains or losses include profit or loss arising from financial instruments at FVTPL and losses on disposition of accounts receivable and losses on foreign currency translation, and profits and losses on foreign exchange differences at FVTOCI, financial assets measured at amortized cost and financial liabilities measured at amortized cost.

(3) Transfer of financial assets The Group transferred account receivables in accordance with the account receivable factoring contract with the Export-Import Bank, etc. In this transaction, if the relevant trade receivables are not recovered at maturity, the Group is not obligated to pay the unrecovered amount of trade receivables to banks. There is no carrying amount of trade receivables accounted for as collateralized borrowing. This is because the Group transferred all or part of the transferred financial assets through factoring of accounts receivable as of the end of current year.

7. Financial risk management

(1) Credit risk Credit risk refers to research risk where clients or the contractual other party can inflict a financial loss on the Group, due to failure to fulfill contractual obligations regarding financial instruments. Primarily, this arises from trade receivables and investment assets.

① Exposure to credit risk The carrying amount of a financial asset refers to the maximum level of exposure to credit risks. The maximum exposure to credit risk as of the end of the current and last years is as follows: (Unit: KRW) Division End of the current year End of the last year Cash and cash equivalents 100,567,267,243 109,686,194,681 Short-term financial instruments 150,846,049,384 100,000,000,000 Trade receivables (*1) 210,368,392,594 159,275,850,982 Other receivables (*2) 27,649,816,660 16,123,373,031

② Impairment loss The Group maintains a reserve to prepare for losses that may arise from trade receivables and investment assets. Reserves from financial asset groups are determined based on past data on collection of similar financial assets. Trade receivables are indicated in the consolidated financial statement with the allowance for losses deducted. The following are the details on the allowance for losses related to the accounts receivables, as well as the accounts receivable in their entire amount before deduction at the end of current and last years: (Unit: KRW) Division End of the current year End of the last year Trade receivables 210,368,392,594 159,275,850,982 Allowance for bad debts - - Net carrying amount of account 210,368,392,594 159,275,850,982 receivables The following are the age of receivables and impaired amounts for each age at the end of current and last years: (Unit: KRW) End of the current year End of the last year Division Total of Total of Impaired amount Carrying amount Impaired amount Carrying amount receivables receivables Within maturity 187,909,227,718 - 187,909,227,718 156,795,235,163 - 156,795,235,163 Maturity ~ 22,211,033,246 - 22,211,033,246 2,480,615,819 - 2,480,615,819 within 3 months 3 ~ 6 months 19,651,630 - 19,651,630 - - - Over 6 months 228,480,000 - 228,480,000 - - - Total 210,368,392,594 - 210,368,392,594 159,275,850,982 - 159,275,850,982 There is no change in provision for bad debts for the current and last years.

dart.fss.or.kr Page 67 (2) Liquidity risk The liquidity risks refer to the risks involved in difficulties in fulfilling the financial liabilities to be repaid by transfer of cash or other financial assets of the Group. The management method of liquidity for the Group focuses on maintaining sufficient liquidity in order to repay the debts within the due date, without damaging the reputation of the Group or suffering excessive losses even during financial hardships. The Group manages liquidity risk by maintaining sufficient cash and cash equivalents and short-term financial instruments.

① The contractual due dates for financial liabilities held by the Group at the end of the current year are as follows. The amounts do not reflect the effects of offsetting agreements. (Unit: KRW) Cash flow per Over 1 year and Division Carrying amount Less than a year contract less than 5 years Trade liabilities 144,000,394,513 144,000,394,513 144,000,394,513 - Other liabilities (*) 19,263,163,367 19,263,163,367 19,243,163,367 20,000,000 Total 163,263,557,880 163,263,557,880 163,243,557,880 20,000,000 (*) Employee-related liabilities not included in financial liabilities are excluded, and the contractual maturity of lease liabilities is indicated in Note 18.

dart.fss.or.kr Page 68 (3) Market risk Market risk refers to the risk where the fair value or future cash flows of a financial instrument will fluctuate due to changes in market prices.

① Exchange rate risk The Group is exposed to the exchange rate risk related to the sales profits and costs indicated in KRW, which is the functioning currency. The major presentation currency for these transactions is USD. A) Exposure to exchange rate risks The following are the carrying amounts of the cash assets and liabilities presented in foreign currency other than the functioning currency at the end of the current and last years: (Unit: KRW) End of the current year End of the last year Division USD JPY CNY USD JPY CNY Assets in foreign currency: Cash and cash 449,195,683 - - 14,132,907,264 255 12 equivalents Trade receivables 129,387,804,356 - - 66,920,020,785 - - Outstanding balance 1,837,010,274 - - 175,917,985 - - Total 131,674,010,313 - - 81,228,846,034 255 12 Liabilities in foreign currency: Trade liabilities 26,023,632,422 - - 16,330,430,832 - - Payables 2,596,042,625 79,734 158,612 3,206,404,068 350,945 152,703 Total 28,619,675,047 79,734 158,612 19,536,834,900 350,945 152,703 The following are the foreign exchange rates applied to the conversion of monetary assets and liabilities in foreign currency: (Unit: KRW) Division End of the current year End of the last year USD 1,088.00 1,157.80 JPY 10.54 10.63 CNY 166.96 165.74

dart.fss.or.kr Page 69 B) Sensitivity analysis If the exchange rates of the key foreign currency, which make up a large part of the financial assets and liabilities of the Group, are increased at the end of current year and last year, the capital, incomes and losses of the consolidated entity would have changed. Such an analysis is based on the assumption of fluctuation, which the Group believes to be reasonably possible at the end of current year. The sensitivity analysis also assumes that no changes are made to other variables, such as the interest rate, etc. The following are the effect of the changes in foreign exchange rate for Korean won (before income tax) for the current and the last years on the losses and gains: (Unit: KRW) End of the current year End of the last year Division Increase by 5% Decrease by 5% Increase by 5% Decrease by 5% point point point point USD 5,152,716,763 (5,152,716,763) 3,084,600,557 (3,084,600,557) JPY (3,987) 3,987 (17,535) 17,535 CNY (7,931) 7,931 (7,635) 7,635

② Interest rate risk The Group's interest-bearing assets are determined at a fixed interest rate, and the Group does not treat fixed interest rate financial instruments as financial instruments measured at fair value. Therefore, the profit and operating cash flows of the Group are actually independent from variations in the market interest rates.

dart.fss.or.kr Page 70 (4) Fair values The following are the carrying amount and fair value of financial assets and liabilities, which include current fair value rank system, as of the end of the current and last years.

(5) Capital management The purpose of the Group’s capital management is for maintaining the existence of the Group as a going concern, minimizing the capital cost for funding, maximizing the profits of the shareholders, and maintaining an appropriate equity structure. The Group is managing its capital based on the liability ratio. The Group manages the capital based on the liability ratio, which is calculated by dividing the total liability in the consolidated financial statement with capital. The following are the liability ratio of the Group at the end of current and last years: (Unit: KRW) Division End of the current year End of the last year Total liabilities 218,317,834,580 157,526,494,823 Total capital 532,284,504,293 472,206,795,494 Liability ratio 41.0% 33.4%

5. Notes on Financial Statements

1. Company overview Silicon Works Co., Ltd. (hereinafter referred to as the “the Company”) was established on 11 November 1999 for the purpose of manufacturing and designing FPD (flat panel display) semiconductor IC, and it is located at 222 Techno 2-ro, Daedeok-gu, Daejeon, Korea. The Company was certified by the Korea Institute for Advance of Technology as a corporate subsidiary research facility in accordance with Article 16 of the Technology Development Promotion Act and Clause 1 of Article 15 of the Enforcement Decree of the same Act on 19 October 2001. The Company has also been designated as a high-tech company in accordance with Clause 1 of Article 9 of the Special Law on the Cultivation of the Special Research and Development Daedeok-gu and more on 23 October 2011. The Company was then listed on KOSDAQ market as of 8 June 2010. After several increases in capital with or without considerations, the amount of paid-in capital of the Company as of the end of the current year is 8,132,150,000 won (16,264,300 issued shares and 50,000,000 authorized shares). The following are the current status of the shareholders of the Company as of the end of the current year: (Unit: Note) Shareholder No. of shares held Ownership stake Remarks LG Corp. 5,380,524 33.08% Largest shareholder National Pension Service 663,664 4.20% - Others 10,220,112 62.72% - Total 16,264,300 100.00%

dart.fss.or.kr Page 116 2. Standards for the preparation of financial statements The Company has prepared financial statements using the K-IFRS, which are separate financial statements based on SKAS No.1027 Separate Financial Statements, and they refer to the financial statements expressed by an investor with joint control or significant influence over the controlling company or the investee, applying any one of the cost methods specified in the followings: the method pursuant to SKAS No.1109 'Financial instrument’, or SKAS No. 1028 ‘Investment in associates and joint ventures’. The significant accounting policies applied to the preparation of the financial statements are described below, and the accounting policies used in the preparation of the financial statements for the current year are the same as those adopted in the preparation of the financial statements for the last year, except for the impacts related to the introduction of the standards and interpretations described below. As described in the accounting policies below, the financial statements have been prepared on a historical cost basis, excluding certain non-current assets and financial assets that are measured at revaluation or fair value at the end of each reporting period. Historical cost is generally measured at the fair value of the consideration paid for acquisition of asset. Fair value is the price that will be received on the sale of an asset or paid on the transfer of liabilities in the normal transaction between market participants at the measurement date. Fair value is determined regardless of whether the price is directly observable or estimated using a valuation technique. In estimating the fair value of an asset or liability, the Company takes into account the characteristics of the assets or liabilities that the market participant considers when determining the price of the assets or liabilities at the measurement date. Fair value for measurement or disclosure purposes is determined in accordance with the principles described above, except for measurements that are in part similar to fair value but not fair value, which include the following: stock-based payment transactions included in the scope of application of Statement of Korea Accounting Standards (hereinafter referred to as SKAS) No.1102 Stock-based payment, lease transactions included in the scope of application of SKAS No.1116 'Lease’, net realizable value of SKAS No.1002 'Inventories’, and value in use of SKAS No.1036 'Impairment of assets’. The executives have a reasonable expectation that the Company has sufficient resources to survive as a going concern for the foreseeable future period at the time of approving the financial statements. Therefore, the executives prepared the financial statements on the premise of a going concern. The Company's financial statements is certified by the board of directors on 27 January 2021, and will be finally approved by the general shareholders’ meeting scheduled to be held on 18 March 2021.

1) The following are the new standards and interpretations introduced from this year and the resulting changes in accounting policies: - SKAS No.1109 ‘Financial instruments’ and SKAS No.1107 ‘Financial instruments’: disclosure (revision) - Effects of the initial application of interest rate indicator reform The hedged items or hedging instruments affected by the current interest rate indicator is changed due to the ongoing interest rate indicator reform. Thus, this amendment revised specific hedging accounting requirements to ensure that hedging accounting can continue to be applied for a period of uncertainty before the hedged items or hedging instruments are changed. However, this amendment is not related to the Company, as the Company does not apply the hedge accounting.

dart.fss.or.kr Page 117 - SKAS No.1116 Lease (revision) - practical and simple method for rent discounts related to COVID-19 This amendment provides practical relief for lessees to account for rent discounts, etc., arising as a direct result of COVID-19. The practical and simple method allows the lessee to choose not to evaluate whether the COVID-19-related rental discount, etc., qualifies as a lease change. The lessee who has made this choice will account for changes in lease fees due to the COVID-19-related rental fee discount, etc., consistent with the method that the lessee accounts for when such changes are not lease changes. The practical and simple method applies only to rental discount discounts, etc., which have occurred as a direct result of COVID 19, and is applied when all of the following conditions are met. - The lease consideration corrected due to the change in lease payments is substantially the same as or less than the lease consideration before the change. - The lease fee reduction only affects the lease payments due before 30 June 2021 (for example, if a rent discount decreases the lease payment owed before 30 May 2021, and increases the lease after 30 May 2021, these conditions are met). - Other lease terms and conditions are not substantially changed.

- Reference to the 'Conceptual System' in the K-IFRS (revision) Refer to the fully revised 'Conceptual System' (2018) of SKAS. However, not all revisions refer to the fully revised ‘Conceptual System’ (2018) where such reference or phrases related to citation are revised. Some phrases are revised in order to clarify whether the referenced ‘Conceptual System' is a 'Conceptual System’ for the preparation and presentation of financial statements' (2007), a 'Conceptual System' (2010), or a newly revised Conceptual System' (2018). Revised for clarity, some other text has been revised to clarify that the definition in the K-IFRS has not been changed to the new definition specified in the fully revised 'Conceptual System' (2018). This document contains revisions to SKAS No.1102, No.1103, No.1106, No.1114, No.1001, No.1008, No.1034, No.1037, No.1038, No.2112, No.2119, No.2120, No.2122 and No.2032.

- Business definition under SKAS No.1103 (revision) This amendment clarifies that although projects generally have deliverables, outputs are not essential for an integrated set of activities and assets to meet the definition of a business. In order for the set of acquired activities and assets to be considered a business, they must at least contain inputs and substantive processes that have the ability to contribute significantly together in the creation of outputs. This amendment removes the evaluation of whether market participants can replace missing inputs or processes and continue to produce output. It also provides guidelines for judgment to help you decide whether or not a substantial course has been acquired. This amendment introduces an optional intensive test that can briefly evaluate whether a set of acquired activities and assets is not a business. In this selective intensive test, if the fair value of the total assets acquired is substantially concentrated in a single identifiable asset or a group of identifiable similar assets, this is not defined as a business. This amendment applies to business combinations with the acquisition date later than the commencement date of the business year which first begins after 1 January 2020, and is applied prospectively to all business combinations and asset acquisition transactions.

dart.fss.or.kr Page 118 - Definition of materiality of SKAS No.1001 and No.1008 (revision) This amendment is intended to make the materiality defined in SKAS No.1001 easier to understand, and not intended to change the basic concept of materiality in SKAS. The notion that non-critical information makes critical information 'uncertain' is included as part of the new definition. The definition of materiality in SKAS No.1008 is replaced with reference to the definition of materiality in SKAS No.1001. In addition, to ensure consistency, the International Accounting Standards Committee has revised other standards and 'concept frameworks' that include definitions of materiality or reference the term 'materiality'. The Company does not expect the enactments and amendments to have a significant effect on the amounts recognized in the Company's financial statements.

2) The financial statements have been enacted and published as of the date of approval, but the effective date has not yet arrived, and the details of the K-IFRS that the Company has not applied in advance are as follows: - Classification of current liabilities and non-current liabilities under SKAS No.1001 (revision) This amendment only affects the presentation of current and non-current liabilities in the financial statement, and does not affect the amount of assets, liabilities and gains or losses, at the time of recognition, or the disclosure information for those items. This amendment clarifies that the classification of current and non-current liabilities is based on the entity's rights that exist at the end of the reporting period, and highlights that it is irrelevant to expectations of whether the entity will exercise its right to delay payment of the debt. Moreover, the revision states that if the loan agreement is complied with at the end of the reporting period, the right exists, and definition of payment is clarified as the transfer of cash, equity instruments, or other assets or services to the counterparty. This amendment is applied retroactively after the commencement date of the first fiscal year starting after 1 January 2023, and early application is permitted.

- Reference to SKAS No.1103 'Conceptual System’ (amendment) This amendment includes the content that SKAS No.1103 refers to the 'Conceptual System' (2018) instead of the previous system ('Conceptual System' (2007)). In addition, it also adds a requirement that in the case of provisions or contingent liabilities that fall within the scope of application of SKAS No.1037, the acquirer applies SKAS No.1037 on the acquisition date in order to determine whether a current obligation exists as a result of past events. In the case of contributions that fall within the scope of application of Interpretation of SKAS No.2121, the acquirer applies interpretation of SKAS No.2121 on the acquisition date in order to determine whether an obligatory event that creates a liability to pay the contribution has occurred. This amendment adds an explicit statement that the acquirer does not recognize contingent assets in a business combination. This amendment applies to business combinations with the acquisition date later than the commencement date of the business year which first begins after 1 January 2020. Early application of the amendments is allowed only when all the amendments under the 'Amendments to the Conceptual System References in the K-IFRS' published together with the amendments are applied before or simultaneously with the amendments.

- SKAS No.1016 ‘Tangible assets’ (revision) This amendment prohibits deducting the sale of goods produced before the tangible assets become usable, i.e., the sale of goods produced before it reaches the place and condition necessary to operate in the manner intended by the executives, from the cost of the tangible asset. Accordingly, such sales and related costs are recognized in profit or loss, and the costs are measured in accordance with SKAS No.1002. In addition, this amendment clarifies the meaning of 'testing whether tangible assets operate normally', and states to evaluate whether the technical and physical performance of an asset can be used for the production or provision of goods or services, lease to others, or management activities. Unless the goods produced are the output of the entity's ordinary activities and the sale amount and costs included in profit or loss are separately indicated in the statement of comprehensive income, the entity should disclose an account in the statement of comprehensive income that includes the amount and cost of the sale, and the amount and cost of the sale. This amendment applies retrospectively only to tangible assets that has reached a location and condition capable of operating in the manner intended by the executives after the commencement date of the earliest period, which is indicated in the financial statements that this amendment is first applied to. The cumulative effect of the initial application of this amendment is recognized by adjusting the opening balance of retained earnings (or other components of equity, if appropriate) at the beginning of the earliest indicated period. This amendment will be applied from the first fiscal year beginning after 1 January 2022, and early application is permitted.

- SKAS No.1037 ‘Loss-bearing contract and contract execution cost’ (amendment) This amendment clarifies that the cost of executing a contract consists of costs directly related to the contract. Costs directly related to a contract consist of the incremental costs (e.g. direct labor cost and direct material cost) to perform the contract and any other cost allocations (e.g. depreciation of tangible assets used in the performance of the contract) which is directly related to the performance of the contract. This amendment applies to contracts for which all obligations have not been fulfilled on the commencement date of the fiscal year that this amendment is first applied to. The comparative financial statements are not rewritten, but instead, the cumulative effect by the first adoption of the amendments is recognized as retained earnings at the date of initial application or, as appropriate, other elements of equity. This amendment will be applied from the first fiscal year beginning after 1 January 2022, and early application is permitted.

- K-IFRS 2018-2020 ‘Annual improvements’ This annual improvement includes some amendments to the first adoption of K-IFRS under SKAS No.1101, SKAS No.1109 “Financial instruments’, SKAS No.1116 ‘Lease’ and SKAS No.1041 'Agricultural, forestry and fisheries businesses'.

dart.fss.or.kr Page 120 ① The first adoption of K-IFRS under SKAS No.1101

This amendment provides an additional exemption with respect to accounting for cumulative translation differences in subsidiaries that become first adopters later than the controlling company. Subsidiaries subject to the exemption provisions in paragraph D16(1) of SKAS No.1101 may choose to measure the cumulative translation difference of all overseas operations by the carrying amount, which is to be included in the controlling company’s consolidated financial statements based on the date of transition of the controlling company in accordance with the K-IFRS. However, the effect of the business combination in which the controlling company acquires a subsidiary as well as adjustments based on the consolidation procedure are excluded. A similar choice may be made if an associate or joint venture applies the exemption provisions in paragraph D16(1) of SKAS No.1101. This amendment will be applied from the first fiscal year beginning after 1 January 2022, and early application is permitted.

② SKAS No.1109 ‘Financial instruments’

This amendment includes only fees received or paid between the entity (borrower) and the lender when applying the '10%' test for assessing whether financial liabilities have been removed. This clarifies that it includes fees paid or received by businesses or lenders on behalf of other parties. This amendment will be applied prospectively to changes and exchanges that have occurred after the initial application date. This amendment will be applied from the first fiscal year beginning after 1 January 2022, and early application is permitted.

③ SKAS No.1116 ‘Lease’

This amendment deleted the contents of the lease improvement reimbursement amount in case 13 of SKAS No.11116. Since this amendment is only relevant to applicable cases, the effective date has not been specified.

④ SKAS No.1041 ‘Agricultural, forestry and fisheries businesses’

This amendment deleted the requirement to exclude tax-related cash flows when measuring the fair value of biological assets. This is in line with the requirements of SKAS No.1113 for ensuring the use of an internally consistent cash flow and discount rate with the fair value measurement in SKAS No.1041, and the entity can determine the most appropriate fair value by choosing whether to use pre-tax or post-tax cash flows and discount rates. This amendment will be applied from the first fiscal year beginning after 1 January 2022, and early application is permitted. The Company is reviewing the effect of the enactments and amendments listed above on the financial statements.

dart.fss.or.kr Page 121 3. Significant accounting policies Significant accounting policies applied by the Company to the preparation of financial statements in accordance with the K-IFRS are described below.

(1) Cash and cash equivalents The Company is classifying investments with cash and cash equivalents with maturities of three months or less after the acquisition date. Equity securities are excluded from cash and cash equivalents, but are included if the redemption date is fixed and the period from acquisition date to redemption date is short- term preferred shares such as preferred shares.

(2) Inventory assets The unit cost of inventory assets is determined by the moving average method. The cost of acquisition includes acquisition costs, conversion costs and other costs necessary to prepare the inventory assets for use. Inventory assets are stated at the lower of cost or net realizable value. The valuation losses and net loss that reduce inventory assets to net realizable value are recognized as expenses in the period where the reduction or loss occurs, and reversal of the loss on the valuation of inventory assets resulting from the increase in net realizable value of the inventory is reversed. It is deducted from the cost of sales of the inventory assets recognized as an expense in the period in which it occurred.

(3) Non-derivative financial assets

① Recognition and initial measurement Trade receivables and debt securities issued are recognized for the first time when they are issued. Other financial instruments and financial liabilities are recognized only when the Company becomes a contracting party for financial instruments. Except for trade receivables that do not include any significant financial elements, financial assets or liabilities are measured at fair value at the date of initial recognition. In the case other than financial assets at FVTPL or financial liabilities at FVTPL, transaction costs, which are directly related to the acquisition of the financial asset or the issue of that financial liability, are added to or deducted from fair value. Trade receivables that do not contain significant financial factors are initially measured at the transaction price.

② Classification and follow-up measurement At initial recognition, financial assets are classified as measured at amortized cost, debt instruments at FVTOCI, equity instruments at FVTOCI, or financial assets at FVTPL. Financial assets are not reclassified after initial recognition unless the Company changes the business model that manages them. In this case, all affected financial assets are reclassified on the first day of the first reporting period after the business model has changed. When a financial asset meets both of the following conditions and is not designated as at FVTPL, the asset is measured at amortized cost. - The financial asset is held under a business model that is intended to hold the asset to receive contractual cash flows. - In accordance with the terms of the financial asset contract, cash flows consisting only of interest payments on the principal and the balance of the principal are generated on a specific date.

dart.fss.or.kr Page 122 When the debt instrument meets both of the following conditions and is not designated as at FVTPL, the asset is measured at FVTOCI. - The debt instrument is held within a business model whose objective is achieved both by collecting contractual cash flows and selling financial assets - In accordance with the terms of the financial asset contract, cash flows consisting only of interest payments on the principal and the balance of the principal are generated on a specific date. Upon initial recognition of an equity instrument that is not held for short swing, the Company may choose to present the subsequent change in the fair value of the investment as other comprehensive income. However, the choice is irrevocable, and is made on a per-investment basis. All financial assets that are not measured at fair value through amortized cost or other comprehensive income described above are measured at FVTOCI. These financial assets include all derivative financial assets. At initial recognition, if a financial asset carried at amortized cost or FVTOCI is designated as at FVTPL and the accounting inconsistency is eliminated or significantly reduced, the Company may designate the financial asset as measured at FVTPL. However, the designation is irrevocable.

1) Business model Since the Company best reflects the way the business is managed and the way information is provided to the executives, it evaluates the purpose of the business model held at the financial asset’s portfolio level. Such information considers the following: - The accounting policies and purpose specified for the portfolio, the actual operation of such policies. This includes the executive's strategy of obtaining or realizing expected cash flows through the acquisition of contractual interest income, maintenance of a certain level of interest return, matching of the duration of the liability that procures financial assets, and the duration of the financial assets. - A method of assessing the performance of financial assets held in a business model, and reporting the assessment to key executives - A method of managing risks that affect the performance of the business model (and the financial assets held in the business model) - Compensation method for the executives (e.g. whether it is based on the fair value of the assets managed or on the contractual cash flows received) - The frequency, amount, timing and reason of sales of the financial assets in the past period, and expectation of future sales activities of financial assets For this purpose, a transaction that transfers a financial asset to a third party in a transaction that does not meet the elimination requirement is not considered as sales. A portfolio of financial assets that meets the definition of short swing or whose performance is assessed based on the fair value is measured at FVTPL.

2) Valuation of whether the contractual cash flow consists solely of principal and interest The principal is defined to be the fair value of a financial assets at initial recognition. Interest is not only composed of consideration for the time value of money, consideration for the credit risk related to remaining principal at a certain period of time, consideration for other cost (e.g. liquidity risk and cost of operation) and fundamental risk associated with lending, but also profit. When evaluating whether contractual cash flows are solely payments of principal and interests, the Company considers the contractual conditions of the financial instrument. When a financial asset contains contractual conditions that modify the timing and amount of contractual cash flows, it is required to

dart.fss.or.kr Page 123 determine whether contractual cash flows that arise during the remaining life of the financial instrument due to such contractual condition are solely payments of principal and interest. The Company considers the following elements when evaluating the above - Conditional circumstances that change the amount or timing of cash flows - Provisions that adjust the contractual coupon rate by including variable interest rate characteristics - Prepayment and maturity extension characteristics - Terms and conditions that limit the Company's claim on cash flows arising from a particular asset If the prepayment amount represents interest on the principal and the remaining principal that are practically unredeemed and includes reasonable additional compensation for the early liquidation of the contract, the early repayment characteristics are consistent with the conditions of paying the principal and interest on a particular date. In addition, the conditions are determined to be satisfied in the following case: for financial assets acquired by significant discounts or premiums on contractual par value, if the intermediate repayment amount substantially represents the contractual par value and contractual interest accruals (but not paid) (in this case, a reasonable additional compensation for early settlement of the contract may be included) and the fair value of the characteristic is minor at the time of initial recognition.

③ Follow-up measurement and profit or loss

1) Financial assets measured at FVTPL These assets are subsequently valued at fair value. Net gain or loss that includes interest or dividend income is recognized in current profit or loss.

2) Financial assets measured at amortized cost These assets are subsequently measured at fair value by using effective interest method. Amortized cost is reduced by impairment loss. Interest income, foreign currency translation gains/losses and impairment loss are recognized in current profit or loss. Any gain or loss arising from disposition shall be recognized in current profit or loss.

3) Debt instruments at FVOCI These assets are subsequently valued at fair value. Interest income is calculated using the effective interest method, and foreign currency translation gains/losses and impairment loss are recognized in current profit or loss. Other net gains and losses shall be recognized in other comprehensive income. Gains or losses on disposition are reclassified into current profit or loss from other comprehensive income.

4) Equity instruments at FVOCI These assets are subsequently valued at fair value. Dividends are recognized in net income unless they expressly recover the investment. Other net income is recognized in other comprehensive income and is never reclassified into current profit or loss.

④ Removal of financial assets The Company shall transfer the contractual right to collect the cash flows of the financial asset if the contractual right to the cash flows of the financial asset is extinguished. If it practically transferred most of the risk and rewards based on ownership of transferred financial asset or if the Group does not hold or

dart.fss.or.kr Page 124 transfer much of the risks and rewards of ownership, then it shall remove the financial asset. The transferred asset shall not be removed if the Company has carried out the transaction to transfer the assets that are recognized in the financial statement, but it holds most of the risks and rewards of ownership of the asset being transferred.

⑤ Offset of financial assets The Company may offset financial assets and financial liabilities and display them on a net basis in the statement of financial position only if it currently has a legally enforceable right of set-off on the assets and liabilities recognized or if it intends to settle them on a net basis, while realizing the assets.

⑥ Impairment of financial assets

1) The Company recognizes loss allowance for expected credit losses on the following assets. - Financial assets measured at amortized cost - Debt instruments measured at FVTOCI - Lease receivables Provisions for losses on trade receivables and other receivables measured at amortized cost are always measured at an amount equal to the expected credit loss for the entire period. When determining whether the credit risk of a financial asset has increased significantly since the initial recognition and when estimating expected credit losses, the Company considers information that is available, reasonable, and supportable without excessive cost or effort. This includes qualitative and quantitative information and analysis based on our past experience and known credit ratings, including forward-looking information. Expected credit loss for the entire period is expected credit loss for all defaults that can occur during the expected life of a financial instrument. The longest period the Company consider when measuring expected credit loss is the longest contract period in which the Company is exposed to credit risk.

2) Measuring expected credit losses The expected credit loss is the probability weight of the credit loss. Credit loss is measured as the present value of all cash deficits (ie, the difference between all contractual cash flows that are expected to be paid under the contract, and all contractual cash flows that are expected to be received). The expected credit loss is discounted at the effective interest rate of the financial asset.

3) Financial assets with damaged credit At the end of each reporting period, the Group assesses whether credits of the financial assets measured at amortized cost are impaired. If one or more events that adversely affect the estimated future cash flows of a financial asset have occurred, the financial asset is impaired. Evidence of credit-impaired financial assets includes the following observable information: - Significant financial difficulties of the issuer or borrower

4) Indication of allowance for credit loss on the financial statement Loss allowances for financial assets and lease payment receivables measured at amortized cost are deducted

dart.fss.or.kr Page 125 from the carrying amount of those assets.

5) Disengagement If there is no reasonable expectation for the recovery of all or part of the financial asset's contractual cash flows, the asset is removed. The Company evaluates the timing and cost of each removal by assessing whether the corporate customer has reasonable expectations for recovery. The Company does not expect that the eliminated amount will be collected significantly. However, each eliminated financial assets may be subject to recovery activities in accordance with the recovery process for the Company's mature amount.

(4) Investment in subsidiaries and associates in separate financial statements The Company's financial statement is a separate financial statement in accordance with SKAS No.1027. The Company accounts for investment assets in subsidiaries and affiliates by selecting the cost method in accordance with SKAS No. 1027. However, as for the K-IFRS separate financial statement on the transition date, 'SKAS's initial selection' of the SKAS No.1101 is applied and the values are measured by using the carrying amount of the past accounting standards as deemed cost. On the other hand, the dividends from the subsidiaries are recognized as profit or loss at the time the right to receive the dividend is defined.

(5) Tangible assets Tangible assets are initially measured at principal amount. The principal amount of tangible assets includes the principal amounts that are directly attributable to the executive's intentional method of bringing the asset to its place and condition, and what is estimated to be incurred in the decommissioning, removal, or restoration of the property. After initial recognition, the carrying amount of tangible assets is designated as accumulated depreciation deducted by accumulated impairment losses. Costs incurred when replacing a part of a tangible asset are included in the asset's carrying amount, if it is probable that future economic benefits arising from the asset will flow to the Company, and the cost can be measured reliably. Where appropriate, it is recognized as a separate asset. At this time, the carrying amount of the replaced portion is derecognized. Other costs incurred in connection with routine repairs and maintenance are recognized in current profit or loss as when they are incurred. Land is not depreciated among tangible assets, and other tangible assets are amortized using the straight- line method, which best reflects the expected consumption pattern of future economic benefits inherent in the asset over its useful life. If the cost of a part of the tangible assets is significant in relation to the total cost of the tangible assets, the part is depreciated separately. The gain or loss arising from the removal of the tangible assets is determined by the difference between the net sale and the carrying amount, and the difference is recognized in other profits or expenses.

dart.fss.or.kr Page 126 The following are the estimated useful lives of tangible assets for the current and last years: Division Durable years Buildings and structures 20, 40 years Machinery 5 years Equipment 4 years Other tangible assets 2~5 years Amortization periods and the amortization methods for intangible assets with finite useful lives are reviewed at the end of each reporting period.

(6) Intangible assets At initial recognition, intangible assets are measured at costs, and the accumulated depreciation after deducting accumulated impairment losses is recognized as the carrying amount. As of the date of their availability, intangible assets are amortized using the straight-line method with no residual value over their estimated useful lives. However, for some intangible assets, since there is no foreseeable limit on the period in which this method is available to use, the useful life of such intangible assets is deemed as indefinite and are not amortized. The following are the estimated useful lives of intangible assets for the current and last years: Division Durable years Goodwill Indefinite Industrial property rights 10 years Software 5 years Membership Indefinite Other intangible assets 5 years Amortization period and amortization method for finite intangible assets are reviewed at the end of each reporting period. Intangible assets with indefinite useful lives are reviewed at the end of each reporting period to determine whether the assessment of their useful life is indefinite. If it is deemed appropriate to change this, it is treated as a change in the accounting estimate. The subsequent expenditures are capitalized only if the future economic benefits of the related asset are increased. Other expenses, including internally generated goodwill and trade names, are immediately expensed.

(7) Goodwill The goodwill corresponds to the consideration paid more than the fair value on net identifiable assets acquired at the time of the business combination, and is counted as intangible assets. Although goodwill is not amortized, it is tested for impairment every year, and displayed as the amount calculated by deducting accumulated impairment loss from the principal amount.

(8) Government subsidies Government subsidies are recognized only if the Company have reasonable assurance that the Company will comply with the conditions attached to it and receive the subsidies.

dart.fss.or.kr Page 127 ① Asset-related subsidies The Company receives government subsidies with a basic condition that the subsidies should be used for acquiring or building intangible assets. When calculating the asset’s carrying amount, the subsidy is deducted, and it is recognized as profits or losses over the useful life of the depreciable assets.

② Income-related subsidies The Company recognizes the government subsidies as current losses and gains, by deducting the subsidies from relevant costs throughout a period of recognizing the relevant principal amount as the cost.

(9) Damage of non-financial assets For all non-financial assets except for the assets arising from employee benefits, inventories, deferred tax assets and non-current assets held for sale, the Company reviews whether there are indications that the asset is impaired and, if so, estimates the recoverable amount of the asset. However, the Company tests impairment annually by comparing the recoverable amount with the carrying amount regardless of the indication of asset impairment for intangible assets with indefinite useful lives and intangible assets that are not yet available. Recoverable amount is estimated for each asset or each cash-generating unit to which the asset belongs if the recoverable amount of an individual asset cannot be estimated. Recoverable amount is decided as the higher between the pure fair value or value in use. The value in use is estimated by discounting future cash flows expected to be generated from the asset or cash-generating unit at an appropriate discount rate, which reflects the current market's assessment on the specific risks of the asset not adjusted when estimating the time value of the money and future cash flows. If the recoverable amount of an asset or cash-generating unit is less than its carrying amount, the carrying amount of the asset is reduced and recognized immediately in current profit or loss. At the end of each reporting period, the Company reviews for assets, excluding goodwill, that there are indications that the impairment loss recognized in past periods no longer exists or has been reduced. Subsequently, reversal is made only if there is a change in the estimate, which is used to determine recoverable amount since the date of the impairment loss. The carrying amount increased by reversal of an impairment loss cannot exceed the depreciation or amortization of the carrying amount, before the impairment loss is recognized in the past. Goodwill acquired in a business combination is allocated to each cash-generating unit that is expected to benefit from the synergies of the business combination. Impairment losses on cash-generating units reduce the carrying amount of goodwill allocated to the cash-generating unit first, and then reduce the carrying amount of the asset in proportion to the carrying amount of each of the other assets in the cash-generating unit. The impairment losses recognized for goodwill cannot be reversed later. At the end of each reporting period, the Company reviews for assets, excluding goodwill, that there are indications that the impairment loss recognized in past periods no longer exists or has been reduced. Subsequently, reversal is made only if there is a change in the estimate, which is used to determine recoverable amount since the date of the impairment loss. The carrying amount increased by reversal of an impairment loss cannot exceed the depreciation or amortization of the carrying amount before the impairment loss is recognized in the past.

dart.fss.or.kr Page 128 (10) Lease

1) In the case where the Company is a lessee The Company evaluates whether the contract is a lease or includes a lease at the contract's commitment date. In the case of a lessee, the Company recognizes right-of-use assets and corresponding lease liabilities for all lease arrangements, excluding short-term leases (less than 12 months) and leases on small underlying assets. The Company recognizes lease payments related to short-term leases and leases on small underlying assets as a straight-line expense over the lease term, unless other systematic criteria better describe the form of the lessee's benefits. Lease liabilities are initially measured at the lease commencement date at the present value of the lease payments not paid as of that day, discounted at the lease's intrinsic interest rate. If the lease's intrinsic interest rate cannot be easily calculated, the lessee's incremental borrowing rate is used. The lease payments included in the lease liability measurement consist of the following items: - Fixed lease (including substantial fixed lease payments and deducting any lease incentives to be received) - Fluctuating lease rates that depend on the index or rate (interest rate). Initially measured using an index or rate (interest rate) on the starting day of lease - Amount expected to be paid in accordance with the residual value guarantee - The exercise price of the purchase option when it is fairly certain that the lessee will exercise the purchase option - The amount borne to terminate the lease if the lease term reflects the lessee's exercise of the option to terminate. The Company presents leased liabilities separately from other liabilities in the financial statement. Lease liabilities are measured by subsequently increasing (using the effective interest method) the carrying amount by reflecting interest on the lease liabilities, and decreasing the carrying amount by reflecting the lease payments paid. The Company remeasures the lease liabilities and makes a corresponding adjustment to the related right to use assets in the following cases: - When the lease period is changed or a change in circumstances or a significant event occurs that causes a change in the evaluation of the exercise of the purchase option. In this case, the lease liabilities are re-measured by discounting the revised lease payments at the revised discount rate. - When the lease fee changes due to a change in the index or rate (interest rate) or due to a change in the amount expected to be paid in accordance with the residual value guarantee. In this case, the lease liabilities are re-measured by discounting the revised lease payments at the unchanged discount rate. However, if there is a change in the lease due to a change in the variable interest rate, a modified discount rate that reflects the change in the interest rate is used. - When the lease contract is changed, and it is not accounted for as a separate lease. In this case, the lease liability is re-measured by discounting the revised lease payments at the revised discount rate as of the effective date of the lease change based on the lease term of the revised lease. Licensed assets consist of the initial measurement of the lease liabilities, the lease payments paid on or before the lease commencement date (deducting the received lease incentives), and the lease opening direct costs borne by the lessee. Licensed assets are measured subsequently by deducting accumulated depreciation and accumulated impairment losses from prime amount.

dart.fss.or.kr Page 129 The estimates of the prime amount incurred by the Company when dismantling and removing the underlying asset, restoring the premises on which the underlying asset is located, or restoring the underlying asset itself as required by the terms of the lease, are recognized and measured in accordance with SKAS No.1037. If such prime amount is not incurred to produce inventory assets, the prime amount of the licensed asset is recognized as part of the prime amount of the licensed assets if the amount is related to the licensed assets. If ownership of the underlying asset is transferred to the lessee prior to the end of the lease term, or if the prime amount of the licensed assets reflects that the lessee will exercise the purchase option, the lessee depreciates the licensed assets from the lease commencement date to the end of the licensed assets’ useful life. In other cases, the lessee depreciates the licensed assets from the lease commencement date to the end of the licensed assets’ useful life or the end of the lease term, whichever is earlier. The Company presents licensed assets separately from other assets in the financial statement. The Company applies SKAS No.1036 to determine whether the licensed assets are impaired, and accounting treatment for the identified impairment loss is described in the accounting policy of 'tangible assets' (refer to Note 3. (5)). The Company does not include variable lease fees (excluding variable lease fees that vary depending on the index or rate (interest rate)) in the measurement of licensed assets and lease liabilities. Such lease fees are recognized in current profit or loss during the period in which the event or condition causing the variable lease fees occurs. As a practical and simple method, the lessee can choose the method of accounting for each leased element and related non-lease elements as a single leased element, not separating the non-lease element from the leased element, for each type of underlying asset. However, the Company does not use the practical and simple method. In a contract that contains one leased element and one or more additional leased or non- lease elements, the lessee allocates the contract consideration to each leased element based on the relative individual price of the leased element, and the total individual price of the non-lease element.

2) In the case where the Company is a lease provider The Company classifies each lease as an operating lease or a finance lease. Leases that transfer most of the risks and rewards of owning the underlying asset are classified as financial leases, and leases that do not transfer most of the risks and rewards of owning the underlying asset are classified as operating leases. In case of an intermediate lessor, the Company accounts for the upper and sub-leases in two separate contracts. The Company classifies sub-leases as financial leases or operating leases based on the licensed assets arising from higher leases rather than underlying assets. The Company recognizes lease fees from operating leases as profits on a straight-line basis or other systematic basis. If other systematic criteria better represent a form of diminishing returns from the use of the underlying asset, the Company applies those criteria. The Company adds the direct cost of opening a lease in the process of concluding an operating lease to the carrying amount of the underlying asset, and recognizes it as an expense over the lease term on the same basis as lease income. In financial leases, the amount received from the lessee is the Company’s net investment on the lease, thus it is recognized as receivables. The Company distributes financial income over the lease term in a way that reflects a certain periodic rate of return to the Company's net investment on leases. After initial recognition, the Company regularly reviews the estimated non-guaranteed residual value, and

dart.fss.or.kr Page 130 recognizes the expected credit loss on lease receivables as a provision for loss, by applying the requirements for derecognition and impairment in SKAS No.1109. Financial lease income is calculated by referring to the total carrying amount of lease receivables. However, in case of financial lease receivables with impaired credit, financial income is calculated by referring to amortized cost (i.e., the amount after deducting allowance for losses). If the contract includes lease and non-lease elements, the Company allocates the contract consideration to each component using SKAS No.1115.

(11) Non-derivative financial liabilities According to the substance of the contract and the definition of financial liabilities, the Company classifies financial liabilities into financial liabilities at fair value through profit or loss and other financial liabilities. These are recognized in the financial statement upon becoming a party to the contract.

① Financial liabilities at FVTPL Financial liabilities at FVTPL include short-term trading financial liabilities or financial liabilities designated as financial liabilities at FVTPL upon initial recognition. Financial liabilities at FVTPL are measured at fair value after initial recognition, and changes therein are recognized in current profit or loss. On the other hand, transaction expenses incurred in connection with the issuance of financial liabilities at FVTPL at the time of initial recognition are recognized in current profit or loss as soon as they are incurred.

② Other financial liabilities Non-derivative financial liabilities other than financial liabilities at fair value through profit or loss are classified as other financial liabilities. At initial recognition, other financial liabilities are measured at fair value deducted by transaction costs directly related to issuance. Subsequently through the application of the effective interest method, other financial liabilities are measured at amortized cost and the associated interest cost is recognized. Financial liabilities are derecognized from the financial statement only when they cease to exist, that is, when the contractual obligation is fulfilled, canceled or expired.

(12) Employee benefits

① Short-term employee benefits Short-term employee benefits that will be settled within 12 months from the end of the reporting period when an employee provides related service are recognized in profit or loss when the service is provided. Short-term employee benefits are measured at undiscounted amount.

② Other long-term employee benefits For other long-term employee benefits that are not to be paid within 12 months from the end of the reporting period in which the employee provided related service, future benefits earned in exchange for the service provided in the current and past years are discounted to the present value. Changes from remeasurement are recognized in current profit or loss in the period in which they arise.

③ Pensions: Defined benefit plan As of the end of the reporting period, defined benefit obligations related to defined benefit plans are

dart.fss.or.kr Page 131 recognized by deducting the fair value of plan assets from the present value of the defined benefit obligation. The defined benefit liability is calculated annually by an independent actuary using the projected unit credit method. Where the net amount calculated by subtracting the fair value of plan assets from the present value of defined benefit obligations is an asset, the asset is recognized only to the extent of its present value of available annual benefits, either in the form of a refund from the plan or a reduction in future contributions to the plan. The remeasurement component of net defined benefit liabilities is a change in the upper limit on recognition of assets, except for actuarial gains and losses, net interest on net defined benefit liabilities, and net interest on defined benefit liabilities. It is immediately recognized in other comprehensive income. The Company's net interest in the defined benefit liabilities (assets) is determined by multiplying the net defined benefit liabilities (assets) by the discount rate determined at the beginning of the annual reporting period, And also by considering changes in net defined benefit liabilities (assets) due to contributions and payments. Net interest expense and other expenses related to the defined benefit plan are recognized in current profit or loss. In the event of a plan amendment or reduction, gains or losses resulting from changes or reductions in benefits for past work are immediately recognized in current profit or loss. The Company recognizes gains and losses on the settlement of a defined benefit plan when the cumulative settlement occurs.

(13) Provisions Estimated liabilities are present (legal or statutory) obligation that exists as a result of a past event, and it is recognized that resources with economic benefits are likely to be leaked in order to fulfill the obligation, and the amount of money required to fulfill the obligation can be estimated reliably. The amount recognized as estimated liabilities is the best estimate of the expenditures required to carry out the present obligation at the end of the reporting period, taking into account the inevitable risks and uncertainties associated with the events and circumstances. When the time value effect of money is significant, the estimated liabilities are valued at the present value of the expenditures expected to carry out the obligation. When a third party is expected to reimburse part or all of the expenditure required to settle the estimated liabilities, the Company recognizes the reimbursement amount and recognize it as a separate asset only when it is almost certain that the entity will be reimbursed. The Company reviews the balance of the estimated liabilities at the end of each reporting period, and adjusts it by reflecting the best estimate as of the reporting date. If the possibility of the outflow of resources in which economic benefits are embedded for the performance of the obligation is no longer high, the related estimated liabilities are reversed. Provision for sales guarantees is recognized when a product or service is sold or provided, and is estimated by weighting average of all possible outcomes and associated probabilities based on past guarantee data. Provisions are used only for expenditures related to initial recognition.

(14) Foreign currency exchange In the preparation of the consolidated financial statement, exchanges in currencies other than functional currencies are recorded at the exchange rate on the date of exchange. At the end of each reporting period, foreign currency monetary items are translated at the closing rate at the end of the reporting period. Non- monetary foreign currency items measured at fair value are translated at the exchange rate at the date the

dart.fss.or.kr Page 132 fair value is determined, and non-monetary items measured at historical cost are translated at the exchange rate at the date of exchange. The foreign exchange differences generated at the time of monetary item's payment and those arising from the conversion of monetary items are recognized as profit or loss's other non-operating income, and other non-operating expenses category when they are related to business activities and when the differences are related to non-operating activities. Then, they are recognized as profit or loss' financial income and financial expense items. When gains or losses on non-monetary items are recognized in other comprehensive income, the effect of foreign exchange fluctuations included in the gain or loss is recognized in other comprehensive income, and any gains or losses are recognized in profit or loss.

(15) Paid-in capital Ordinary shares are classified as equity. Incremental costs directly attributable to equity transactions are deducted from equity as a net amount reflecting tax effects. If the Company reacquires its own equity instruments, such instruments are directly deducted from the capital as reacquired shares. The gain or loss is not recognized in current profit or loss when the entity purchases, sells, issues or incinerates its equity instruments. If the Company or another entity in the Company acquires and retains treasury stock, the consideration paid or received is recognized directly in equity.

(16) Revenue from contracts with customers As of 1 January 2018, the Company first applies SKAS No.1115 to apply a five-step revenue recognition model (① identifying contracts → ② identifying performance obligations → ③ identifying market price → ④ allocating market prices to performance obligations → ⑤ recognizing revenue when fulfilling performance obligations) to all types of contracts and recognize its profits.

① Contract identification The Company identifies the contract with customer when it meets all of the following criteria: - The contractual parties approve the contract and commit to perform their respective obligations. - The rights of each party relating to the goods or services to be transferred are identified. - The payment terms of the goods or services to be transferred are identified. - There is a commercial practicality in the contract. - There is a high possibility of collecting the consideration entitled to be received from customer for the goods or services to be transferred. The Company identifies a supply and service contract that meets all of the above criteria as contract with customer.

② Identifying performance obligations At contract inception, the Company reviews the promised goods or services in the contract with the customer to identify the promise to transfer either of the following to the customer as a performance obligation: - A distinguishable good or service (or a bundle of goods or services)

dart.fss.or.kr Page 133 - A series of distinguishable goods or services that are substantially the same and have the same transfer method to the customer The performance obligation of the Company identified in the contract with the customer is the provision of the promised product and service.

③ Market price calculation The Company refers to the terms of the contract and the business practices of the Company to determine the market price. The transaction prices are the amounts from the rights to receive the payments after the Company transfers the goods or services promised to the customer, but the amounts collected on behalf of the third party are excluded. The Company calculates the market price as the consideration received from customer for supply and service of the product. However, the consideration received from customer may change because the Company allows returning of products as stated in the contract for product supply. The Company estimates the variable consideration using an expected value method that it expects to better predict the consideration to be entitled to, and recognizes revenue by including the variable consideration in the transaction price only to an amount that is highly probable that it will not reverse a significant portion of the cumulative revenue already recognized when the return period has expired. Among the amount of consideration received or to be received by the Company, the Company appropriates it as a refund liability and recognizes it as a new asset for the right to recover the returned asset. In addition, the Company recognizes it as a new asset for the right to collect the returned assets.

④ Allocating transaction price to performance obligation The Company allocates the transaction price to each performance obligations in an amount, which indicates the right to receive payments in return of the transfer of promised goods or services to customer. Since the performance obligations of the Group specified in the contract that the Company has entered into with customer are product supply and service provision, and consist of a single performance obligation identified by distinguished goods and services, the transaction price shall not be allocated.

⑤ Recognition of revenue when fulfilling performance obligations The Company satisfies its performance obligation by transferring promised goods or services to the customer, and recognizes transaction price allocated to performance obligation as revenue when the customer controls goods or services. The Company recognizes revenue by viewing the performance obligation of product supply and service provision as being satisfied at a point in time. In particular, as for service provision, the Company shall recognize revenue as a performance obligation satisfied at a point in time since the assets created by the Group's performance do not have an alternative use to the entity itself, and that the performance completed to date does not meet the requirements of the performance obligation, which requires performance to be carried out over a period during which payment claim is enforceable.

(17) Financial revenues and financial costs Financial earnings include interest income, converted profit, foreign exchange gains on foreign currency financial instruments, and net profit on financial assets measured at FVTPL. Interest income is recognized in current profit or loss using the effective interest method over the period. Financial expenses include interest costs on borrowings and converted loss and foreign exchange loss on

dart.fss.or.kr Page 134 foreign currency financial instruments, and net profit on financial assets measured at FVTPL. Interest expense on borrowings is recognized in current profit or loss by using the effective interest rate method. The effective interest method accurately matches the future cash payment estimated during the expected duration of the financial instrument or the current value of the received amount with the total carrying amount of the financial asset or the amortized cost of the financial liability. When calculating the interest income or interest expenses, the effective interest is applied to the total carrying amount of the assets (if the credit of the asset is undamaged) or to the amortized cost of the liabilities. However, for financial assets that have subsequently been credit-impaired since initial recognition, interest income is calculated by applying the effective interest rate to the amortized cost of the financial asset. If the asset is no longer considered credit-impaired, the interest income shall be calculated by applying the effective interest rate to the total carrying amount.

(18) Income tax Income tax expense consists of current and deferred tax and is recognized in current profit or loss, except to the extent that it is recognized in other comprehensive income or directly in equity or in transactions or events.

① Current income tax Current tax is calculated based on taxable income for the year. Taxable income differs from current profit or loss in the consolidated statement of income as it excludes profit or loss, tax exempt items and non- taxable items that are added to or deducted from other taxable income in the consolidated income statement. Accrued income taxes payable, which is related to the Company's current income tax, are calculated using enacted or substantively enacted tax rates.

② Deferred income tax When measuring the deferred tax liabilities and the deferred tax assets, the Company reflects the tax effects at the end of the reporting period based on the expected method of collecting or paying the carrying amount of the assets or liabilities. For the temporary differences to add for subsidiaries, associates and joint venture investment equity, the Company can control the extinction time point of the temporary differences, and deferred tax liabilities are recognized for all cases except where there is a high possibility that the it would not be extinct within the predictable future. Also, deferred tax assets that arise due to temporary differences to deduct are recognized in cases where there is a high possibility that the temporary differences will be extinct in predictable future, and that taxable income for which the temporary differences can be used will occur. The carrying amount of a deferred income tax asset is reviewed at the end of each reporting period and the it is reduced when it is no longer probable that sufficient taxable profit will be available against which the deductible temporary difference can be utilized. Deferred tax assets and liabilities are measured using tax rates that are expected to apply to the period that the asset is realized, or the liability is settled, based on tax legislation enacted or substantively enacted at the end of the reporting period. Deferred income tax assets and liabilities are offset against income taxes levied by the same taxation authority, and are only settled to the extent that the Company has the legal right to set off the recognized amount and the intent is to settle the current tax liabilities and assets on a net basis. If there exists income tax amount that additionally occur from dividend payment, it is recognized at the time point when the

dart.fss.or.kr Page 135 liabilities related to dividend payment are recognized.

(19) Earnings per share The Company calculates basic and diluted earnings per ordinary share for the year and net profit for the period, and presents it in the consolidated income statement. Basic earnings per share is calculated by dividing the net profit or loss of controlling shareholder for the ordinary shares by the weighted average ordinary shares of the shares circulated during the reporting period. Diluted EPS is calculated by adjusting the profit or loss and the weighted average number of ordinary shares attributable to ordinary shares, by considering the effect of dilutive potential ordinary shares, such as share-based compensation granted to employees.

(20) Business combinations Business combinations are accounted for using the acquisition method, except for combinations of entities and businesses under common control. Transfer considerations are generally measured at fair value as the same way that identifiable net assets are measured at fair value. When goodwill is generated as a result of a business combination, impairment tests are conducted annually, and the bargain purchase gain is recognized immediately in current profit or loss. Acquisition-related costs are expensed in the period in which they are incurred and provided for services, except for the cost of issuance of debt securities and equity securities, which are recognized in accordance with K-IFRS No.1032 and K-IFRS No.1109. Transfer considerations do not include any amounts related to the settlement of existing relationships. The settlement of existing relationships is generally recognized in current profit or loss. Contingent consideration is measured at fair value on the acquisition date. Contingent consideration classified as equity are not remeasured and subsequent settlements are accounted for in equity. When the contingent consideration is not classified as equity, the change in fair value of the conditional consideration is subsequently recognized in profit or loss.

dart.fss.or.kr Page 136 4. Important judgment and the major source of estimated uncertainty In applying our accounting policies described in Note 3, the executives should make decisions (except for matters pertaining to the estimates) that have a significant effect on the amounts recognized in the financial statements, and make estimates and assumptions about the carrying amount of assets and liabilities, which cannot be easily identified from other sources. The estimates and related assumptions are based on past experience and other factors deemed relevant. Additionally, actual results may differ from these estimates. Estimates and basic assumptions are continually reviewed. Amendments to accounting estimates are recognized in the period in which the amendment is made, if the amendment affects only that period. Also, if it affects both the current and future periods, it is recognized in the period in which the amendment was made and in the future.

(1) The executive's judgment The following notes include information on key executives judgments related to the application of accounting policies that have a significant effect on the amounts recognized in the consolidated financial statements: - Note 3: Significant accounting policies

(2) Uncertainty of assumptions and estimates Information about uncertainties in the assumptions and estimates that have significant risk of material adjustment within the next reporting period are included in the following notes: - Note 12: Inventory assets - assumption on inventory asset valuation allowance setting - Note 17: Lease liability - judgment on lease duration - Note 19: Provisions - assumptions on the likelihood and amount of outflow of resources - Note 31: Measurement of defined benefit obligation - main actuarial assumptions

(3) Fair value measurement As the accounting policy and disclosure of the Company require the measurement of fair value for many financial and non-financial assets and liabilities, the Company established the policies and procedures for the evaluation of fair value. The policies and procedures include the operations of the evaluation department responsible for the review on the measurement of every significance fair value, including fair value classified into Level 3 in the hierarchy system of fair value, and the results are directly reported to the financial executive. The evaluation department is regularly reviewing significant input variables and evaluation adjustment which cannot be observed. If any third party information such as the broker price or evaluation organization is used in measuring fair value, the evaluation based on information acquired from the third party by the evaluation department includes the classification per level in the hierarchy system of fair value. The Company is making a decision on whether or not to conclude if requirements in the applicable standard are met. If the fair value of an asset or liability is measured, the Company uses the input variable which can be observed from the market as much as possible. The fair values are classified within the hierarchy system of fair values based on input variables used in the valuation techniques as below; - Level 1: Publicly announced price not adjusted in the active market accessible to the same asset or liability on the measured day

dart.fss.or.kr Page 137 - Level 2: Input variable which can be observed directly or indirectly to the asset or liability other than publicly announced price - Level 3: Input variable which cannot be observed to the asset or liability If many input variables used for measuring the fair value of an asset or liability are classified into different levels within the hierarchy system of fair values, the Company classifies the entire fair value measurements into the same level with the input variable of lowest level in the hierarchy system of significant fair value system over the entire measurements. The Company also recognizes the transfer between levels in the hierarchy system at the end of the reporting period, in which the variation occurred. The following note includes detailed information on the assumptions used in measuring fair value: - Note 6: Financial risk management

There is no carrying amount of trade receivables accounted for as collateralized borrowing as the Company transferred all or part of the transferred financial assets through factoring of accounts receivable as of the end of current year.

dart.fss.or.kr Page 140 6. Financial risk management

(1) Credit risk Credit risk refers to risk of financial loss to the Company caused by clients or the other party on the contract failing to fulfill contractual obligations regarding financial instruments. It mainly occurs from trade receivables and investment assets.

① Exposure to credit risk The carrying amount of a financial asset indicates the maximum level of exposure to credit risks. The maximum exposure to credit risk as of the end of the current and last years is as follows: (Unit: KRW) Division End of the current year End of the last year Cash and cash equivalents 100,049,526,121 108,327,650,225 Short-term financial instruments 150,000,000,000 100,000,000,000 Trade receivables (*1) 210,368,392,594 159,275,850,982 Other receivables (*2) 27,506,763,596 16,000,169,213 Financial assets at FVTPL 163,039,267 270,925,629 Total 488,087,721,578 383,874,596,049

(*1) Trade receivables classified as financial assets at FVTOCI are included. (*2) Lease receivables are included.

② Impairment loss The Company maintains a reserve to prepare for losses that may be caused by trade receivables and investment assets. Reserves from financial asset groups are determined based on past data on collection of similar financial assets. Trade receivables are indicated in the financial statement with the allowance for losses deducted. The following are the details on the allowance for losses related to the accounts receivables, as well as the accounts receivable in their entire amount before deduction at the end of current and last years: (Unit: KRW) Division End of the current year End of the last year Trade receivables 210,368,392,594 159,275,850,982 Allowance for bad debts - - Net carrying amount of account 210,368,392,594 159,275,850,982 receivables

(2) Liquidity risk The liquidity risks refer to the risks to the Company having difficulties on fulfilling the financial liabilities to be repaid by transfer of cash or other financial assets. The method of management of liquidity for the Company focuses on maintaining sufficient liquidity in order to repay the debts within the due date, without damaging the reputation of the Company or suffering excessive losses even during financial hardships. The Company manages liquidity risk by maintaining sufficient cash and cash equivalents and short-term financial instruments.

① The following are the contractual due dates for financial liabilities held by the Company at the end of the current year. The amounts do not reflect the effects of offsetting agreements. (Unit: KRW) Cash flow per Over 1 year and less Division Carrying amount Less than a year contract than 5 years Trade liabilities 144,000,394,513 144,000,394,513 144,000,394,513 - Other liabilities (*) 20,253,490,483 20,253,490,483 20,233,490,483 20,000,000 Total 164,253,884,996 164,253,884,996 164,233,884,996 20,000,000

(*) Employee-related liabilities, which are not included in financial liabilities, are excluded. The contractual maturity of lease liabilities is indicated in Note 17.

dart.fss.or.kr Page 142 (3) Market risk Market risk refers to risk where the fair value or future cash flows of a financial instrument will fluctuate due to changes in market prices.

① Exchange rate risk The Company is exposed to the exchange rate risk related to the sales profits and costs indicated in KRW, which is the functioning currency. The major presentation currency for these transactions is USD. A) Exposure to exchange rate risks The following are the carrying amounts of the cash assets and liabilities presented in foreign currency other than the functioning currency at the end of the current and last years: (Unit: KRW) End of the current year End of the last year Division USD JPY CNY USD JPY CNY Assets in foreign currency: Cash and cash 21,096,102 - - 14,132,907,264 255 12 equivalents Trade receivables 129,387,804,356 - - 66,920,020,785 - - Receivables 1,837,010,274 - - 175,917,985 - - Total 131,245,910,732 - - 81,228,846,034 255 12 Liabilities in foreign currency: Trade liabilities 26,023,632,422 - - 16,330,430,832 - - Payables 2,870,986,666 79,734 785,220,580 3,403,789,031 350,945 574,291,149 Total 28,894,619,088 79,734 785,220,580 19,734,219,863 350,945 574,291,149

The following are the foreign exchange rates applied to the conversion of monetary assets and liabilities in foreign currency: (Unit: KRW) Division End of the current year End of the last year USD 1,088.00 1,157.80 JPY 10.54 10.63 CNY 166.96 165.74 B) Sensitivity analysis If the exchange rates of the key foreign currency that compose a large part of the financial assets and liabilities of the Company increase at the end of current year and last year, the capital, incomes and losses of the consolidated entity would have changed. Such an analysis is based on the assumption of fluctuation the Company reasonably believes to occur at the end of current year. The sensitivity analysis also assumes that other variables, such as the interest rate, do not change. The following are the effect of the changes in foreign exchange rate for Korean won (before income tax) for the current and the last years on the losses and gains:

dart.fss.or.kr Page 143 (Unit: KRW) End of the current year End of the last year Division Increase by 5% point Decrease by 5% point Increase by 5% point Decrease by 5% point USD 5,117,564,582 (5,117,564,582) 3,074,731,309 (3,074,731,309) JPY (3,987) 3,987 (17,535) 17,535 CNY (39,261,029) 39,261,029 (28,714,557) 28,714,557

② Interest rate risk The Company's interest-bearing assets are fixed at fixed interest rates and the Company does not treat fixed- rate financial instruments as fair value measured financial instruments. Therefore, the profit and operating cash flows of the Company are actually independent from variations in the market interest rates.

(4) Fair values The following are the carrying amount and fair value of financial assets and liabilities that include current fair value rank system as of the end of the current and last years:

① End of the current year (Unit: KRW) Division Carrying amount Level 1 Level 2 Level 3 Total Financial assets measured at fair value: Financial assets measured at FVTPL 163,039,267 - - 163,039,267 163,039,267 Trade receivables (*1) 105,806,689,122 - - - - Subtotal 105,969,728,389 - - 163,039,267 163,039,267 Financial assets not measured at fair value: Cash and cash equivalents 100,049,526,121 - - - - Short-term financial instruments 150,000,000,000 - - - - Trade receivables 104,561,703,472 - - - - Other receivables (*2) 22,653,208,915 - - - - Subtotal 377,264,438,508 - - - - Total 483,234,166,897 - - 163,039,267 163,039,267 Financial liabilities not measured at fair value: Trade liabilities 144,000,394,513 - - - - Other liabilities (*2, *3) 20,253,490,483 - - - - Total 164,253,884,996 - - - -

(1) Summary of fair value evaluation procedures [Non-derivative financial assets] The Group classifies non-derivative financial assets into four categories: financial assets recognized in the current profit or loss, financial assets held to maturity, loans and receivables, and transferable financial assets, which are recognized in the consolidated financial statement when the Group becomes a contractual party. Non-derivative financial assets are measured at fair value at initial recognition. If they are not financial assets recognized in the current profit or loss, the transactional cost directly related to the acquisition of the financial assets are added to the fair value at initial recognition.

① Financial assets recognized in the current profit or loss Short-term trading financial assets or financial assets designated as FVTPL at initial recognition are classified as financial assets at FVTPL. Financial assets recognized in the current profit or loss are measured at fair value after initial recognition, and changes in fair value are recognized in the current profit or loss. Meanwhile, transactional costs related to acquisition incurred at the time of initial recognition are recognized in the current profit or loss as soon as they are generated.

② Financial assets held to maturity They are classified as financial assets held to maturity if their maturity is fixed and the amounts to be paid are fixed or determinable for non-derivative financial assets, in the case where the Group has the active intent and ability to hold to maturity. After initial recognition, they are measured at amortized cost using the effective interest method.

③ Loans and receivables Non-derivative financial assets with fixed or determinable payments and their transaction price not quoted in an active market are classified as loans and receivables. After initial recognition, they are measured at amortized cost using the effective interest rate method.

④ AFS financial assets Non-derivative financial assets designated as available for sale or not classified as financial assets recognized in the current profit or loss, financial assets held to maturity or loans and receivables are classified as available-for-sale (AFS) financial assets. They are measured at fair value after initial recognition, and changes in fair value are recognized in other comprehensive profit or loss. However, equity securities that do not have a quoted market price in an active market and whose fair value cannot be measured reliably are measured at prime amount.

(1) Assets As of the end of 2020, the Company's total assets is 750.6 billion won, which is increased by 120.9 billion won from the last year due to the increase in sales receivables and inventories. Of these, current assets account for 83.84% of total assets and non-current assets account for 16.16% of total assets.

(2) Liabilities As of the end of 2020, the Company's total liabilities is 218.3 billion won, which is increased by 60.8 billion won from the last year due to trade liabilities resulting from an increase in volume, of which current liabilities stood at 95.77% or 209.1 billion won, and non-current liabilities reached 9.2 billion won or 4.23%.

(3) Capital As of the end of 2020, the Company's total capital was 532.3 billion won, an increase of 60.1 billion won from the last year. The main factor is that net income excluding dividends, etc., contributed to the surplus of capital.

This can be attributed to an increase in large Criver-IC sales due to an increase in OLED TV and LCD TV units, an increase in home economy demand due to the impact of Covid-19, and an increase in mobile DDI sales due to an increase in mobile units. With the increase in the proportion of the high-end product line mainly on OLED, gross profit reached 296 billion won, an increase of 83.1 billion won from the last year, and the SG&A expenses increased by 36.2 billion won from the last year due to increased personnel and R&D expenses for business expansion, and operating profit increased by 47 billion won to 94.2 billion won.

However, operating profit recorded an increase of about 99.4% compared to the last year due to the increase in sales and gross profit exceeding them.

D. Main points for consideration As the Company's sales and purchase amounts are based on USD-based unit price calculation and settlement, changes in the KRW/USD exchange rate are the main factors affecting our business performance. In addition, as the market price of the wafer varies depending on the supply and demand environment, and the share of foundries is the largest among the Company's manufacturing costs, to the Company shall continuously check changes in wafer price.
