The total number of the Company’s consolidated subsidiaries as of December 31, 2021 was 23, including SK Broadband Co., Ltd. and PS&Marketing Co., Ltd.

(1)	Wireless business

Wireless telecommunications companies provide services based on competitive strengths in handheld devices, affordable pricing, network coverage and an extensive contents library. The Company continues to maintain its reputation as the unparalleled premium network operator in the 3G, 4G and 5G markets on the basis of its technological leadership and network management technology. With the world’s first commercialization of 5G technology in 2019, the Company continues to maintain its position as the top network operator in the 5G era and strives to provide differentiated services to its customers.

In order to strengthen its sales channels, the Company has been offering a variety of fixed-line and wireless telecommunication convergence products through its subsidiary, PS&Marketing Co., Ltd. (“PS&Marketing”). PS&Marketing provides differentiated service to customers through the establishment of new sales channels and product development. Through its subsidiaries Service Ace Co., Ltd. (“Service Ace”) and Service Top Co., Ltd., the Company operates customer service centers in Seoul and provides telemarketing services. Additionally, SK O&S Co., Ltd. (“SK O&S”), the Company’s subsidiary responsible for the operation of the Company’s networks, including its 5G network, provides customers with quality network services and provides the Company with technological know-how in network operations.

The Company plans to maintain stable growth in the sales of its wireless business based on a solid expansion in the number of 5G subscribers, while continuously enhancing profitability by pursuing efficient investments in, and operation of, its wireless networks and the stabilization of market competition.

The Company has been expanding the subscriber base of its subscription business by providing competitive subscription products in cooperation with various domestic and international partners. The Company’s metaverse business has also been steadily growing by offering social community functions. In addition, the Company is continuing to develop optimally personalized product packages leveraging artificial intelligence (“AI”) capabilities that integrate the Company’s various wireless services.

(2)	Fixed-line business

SK Broadband Co., Ltd. (“SK Broadband”) is engaged in providing telecommunications, broadcasting and new media services and various other services that are permitted to be carried out by SK Broadband under relevant regulations, as well as business activities that are directly or indirectly related to providing those services. In 1999, SK Broadband launched its high-speed Internet service in Seoul, Busan, Incheon and Ulsan and currently provides such services nationwide. SK Broadband also commercialized its TV-Portal service in July 2006 and its IPTV service in January 2009 upon receipt of permit in September 2008. In addition, SK Broadband’s merger with Tbroad Co., Ltd. (“Tbroad”) obtained all requisite regulatory approvals in January 2020, and the merger became effective as of April 30, 2020. In 2021, sales of the Company’s fixed-line business amounted to Won 4.05 trillion, primarily due to increases in the number of IPTV and high-speed internet subscribers, data traffic and new corporate customers.

(3)	Other businesses

The commercial retail data broadcasting channel business offers an interactive service that integrates television home shopping and data shopping services. Such service allows television viewers to use video-on-demand (“VOD”) services to purchase products sold on television home shopping channels, which were previously only available for purchase in real-time when such relevant programming was being broadcast.

In order to secure core competencies at an early stage and achieve differentiation, the Company has been actively searching for high-efficiency television channels while increasing the competitiveness of its content production capacity by building the Company’s own media center and adopting a media wall with the objective of transforming it into an eco-friendly digital studio. In addition to enhancing the convenience of shopping experience by offering various media content on its mobile live platform, the Company was the first in the industry to launch a cloud-based television application service, “Stoa ON,” which provides personalized digital television shopping services. Furthermore, the Company has been establishing itself as a leading shopping channel service provider by securing a diverse product portfolio and engaging in product development in areas ranging from fashion to health food. Within three years following the spin-off of SK stoa Co., Ltd. (“SK Stoa”) into a separate entity, its commercial retail data broadcasting channel business has attained a leading position in the television commerce (“T-commerce”) market. In 2021, sales of the Company’s commercial retail data broadcasting channel business amounted to Won 316.2 billion.

[Wireless Business]

A.	Industry Characteristics

The telecommunications services market can be categorized into telecommunications services (such as fixed-line, wireless, leased line and value-added services) and broadcasting and telecommunications convergence services. Pursuant to the Telecommunications Business Act, the telecommunications services market can be further classified into basic telecommunications (fixed-line and wireless telecommunications), special category telecommunications (resale of telecommunications equipment, facilities and services) and value-added telecommunications (Internet connection and management, media contents and others). The size of the domestic telecommunications services market is determined based on various factors specific to Korea, including size of population that uses telecommunication services and telecommunications expenditures per capita. While it is possible for Korean telecommunication service providers to provide services abroad through acquisitions or otherwise, foreign telecommunication services markets have their own characteristics depending, among others, on the regulatory environment and demand for telecommunication services.

The Korean mobile communication market is considered to have reached its maturation stage with more than a 100% penetration rate. However, the Korean mobile communications market continues to improve in the quality of services with the help of advances in network-related technology and the development of highly advanced smartphones which enable the provision of New ICT services for advanced multimedia contents, mobile commerce, mobility and other related services.

The Korean mobile communication market includes the entire population of Korea with mobile communication service needs, and almost every Korean is considered a potential user. Sales revenue related to data services has been growing due to the increasing popularity of smartphones and high-speed wireless networks. There is also a growing importance to the B2B segment, which creates added value by selling and developing various solutions. The telecommunications industry is a regulated industry requiring license and approval from the MSIT.

In the wireless business, industry players compete on the basis of the following three main competitive elements:

(i) brand competitiveness, which refers to the overall sense of recognition and loyalty experienced by customers with respect to services and values provided by a company, including the images created by a company’s comprehensive activities and communications on top of the actual services rendered;

(ii) product and service competitiveness, which refers to the fundamental criteria for wireless telecommunications services, including voice quality, service coverage, broad ranges of rate plans, diversified mobile Internet services, price and quality of devices and customer service quality, as well as the ability to develop new services that meet customer needs in a market environment defined by convergence; and

(iii) sales competitiveness, which refers to novel and diversified marketing methods and the strength of the distribution network.

D.	Business Overview and Competitive Strengths
---	---

In 2021, the Company successfully completed the Spin-off of its ICT portfolio, including its security, commerce and mobility businesses, and engaged in corporate reorganization with the vision of becoming a “fixed-line and wireless telecommunication-based service company.” Despite the Spin-off, the Company managed to record Won 16.7 trillion in operating revenue and Won 1.39 trillion in operating profit for the year ended December 31, 2021 on a consolidated basis and Won 12.1 trillion in operating revenue and Won 1.1 trillion in operating profit for the period on a separate basis by maintaining a leading position in the 5G market improving the operations and profit margin of its fixed-line and media businesses.

In the MNO business, the Company secured 9.87 million 5G subscribers as of December 31, 2021 through innovations and quality enhancements in its 5G services. The Company also solidified its status as the top MNO service operator while maintaining market stability through innovations in its distribution channels in response to the contactless environment and rational market operations. The Company was also ranked as the top service provider with respect to certain key metrics such as transmission speed in several 5G service quality evaluations conducted by the MSIT to date.

SK Telink, a consolidated subsidiary of the Company, operates its MVNO service, “SK 7Mobile,” which is offered at reasonable rates and provides excellent quality. SK Telink is increasing its efforts to develop low-cost distribution channels and create niche markets through targeted marketing towards customers including foreign workers, middle-aged adults and students.

SK O&S, a subsidiary of the Company responsible for the operation of the Company’s base stations and related transmission and power facilities, offers quality fixed-line and wireless network services to customers, including mobile office products to business customers. In addition, Service Ace is developing its competence as a marketing company while providing top-quality customer service.

PS&Marketing, a subsidiary of the Company, provides a sales platform for products of the Company and SK Broadband including fixed-line and wireless telecommunication products that address customers’ needs for various convergence products. PS&Marketing provides differentiated service to clients through the establishment of new sales channels and product development.

[Fixed-line Business]

A.	Industry Characteristics

The domestic telecommunication service industry displays the typical characteristics of a domestic industry given that its coverage area is limited to Korea. As a result, the size of the industry is greatly affected by the domestic economic factors including the domestic user population and the level of telecommunication service expenditures in light of the domestic income level. Domestic telecommunication companies may expand overseas through acquisitions or direct expansion, but the overseas telecommunication service industries are subject to inherently different industry characteristics from the domestic one, depending on the regulatory and demand characteristics of each country.

The broadcasting business involves the planning, programming or production of broadcasting programs and transmission to viewers through telecommunication facilities. The broadcasting market can be categorized into terrestrial broadcasting, fixed-line TV broadcasting, satellite broadcasting and programming-providing businesses, in each case pursuant to the Broadcasting Act, as well as Internet multimedia broadcasting business pursuant to the Internet Multimedia Broadcast Services Act. The Company engages in the fixed-line TV broadcasting business, which is defined as the business of managing and operating fixed-line TV broadcasting stations (including their facilities and employees for the purpose of providing multi-channel broadcasting) and providing broadcasts through transmission and line facilities. The Internet multimedia broadcasting refers to the broadcasting of programs through a combination of various contents including data, video, voice, sound and/or e-commerce, including real-time broadcasting, while guaranteeing a consistent service quality through a bidirectional Internet protocol using a broadband integrated information network.

As a result of the government’s direct and indirect control over the fixed-line telecommunications industry, ranging from service licensing to business activities, the industry’s overall growth potential and degree of competition are greatly affected by the government’s regulatory policies. The fixed-line telecommunications industry is also a technology-intensive industry that evolves rapidly and continuously through the development of communications technology and equipment, which requires proactive responses in meeting the needs of subscribers by developing new services and penetrating the market. Fixed-line telecommunications services have become universal and essential means of communication and act as the foundation for integration and convergence with various other services. The essential nature of such services provides stable demand, resulting in low sensitivity to economic conditions.

In addition, the Korean fixed-line services industry is marked by a high level of market concentration, as the government is highly selective in granting telecommunications business licenses. While the competitive landscape of the fixed-line and wireless services markets is dominated by its three leading operators, the Company (including SK Broadband), KT and LG U+, the intensity of competition is growing as digitalization of communication technologies and devices leads to the convergence of fixed-line and wireless services, as well as broadcasting and telecommunications, and technology for faster data communication services is developed.

In the high speed internet services market, the demand for faster and more reliable premium Giga Internet services is increasing due to the growth in usage of home mobile networks using Wi-Fi and an increased consumption of high-definition large media content.

With the mergers and acquisitions among IPTV service providers and multiple service operators, the paid broadcasting market has reorganized around IPTV operators, and companies are moving away from competition based on subscriber base expansion to competition based on media platform services. The transition to a contactless service society due to COVID-19 has led to increased consumption of paid content by viewers, accelerating competition through the ability to source unique contents. The Company expects new growth in the home platform domain by providing customized services using ICT convergence technologies such as AI and big data in addition to differentiated contents.

In the corporate business market, the Company is continuing its efforts to generate stable returns by securing growth drivers in new service areas such as cloud computing, while also strengthening its competitiveness in the traditional fixed line-based business through expansion of core infrastructure including internet data centers, which have seen an increase in market demand recently.

C.	Cyclical Nature and Seasonality
---	---

High-speed Internet and fixed-line telephone services operate in mature markets that are comparatively less sensitive to cyclical economic changes as the services provided by different operators have become less differentiated. TV services have become necessities that provide broadcasting, and the market, which is subject to a subscriber-based business model, has little sensitivity to cyclical economic changes. The telecommunications services market overall is not expected to be particularly affected by economic downturns due to the low income elasticity of demand for telecommunication services.

2. Dividends and Others

A.	Dividend Policy

Our fundamental shareholder distribution policy seeks to enhance long-term shareholder returns through stable cash dividends based on the Company’s performance and through the enhancement of corporate value based on sustained growth. To this end, the Company strives to enhance its corporate value under its capital management principle of balancing investment for growth and shareholder returns.

The Company plans to set 30% to 40% of its “EBITDA – capital expenditures” on a separate basis as the total amount of dividends, subject to each fiscal year’s business environment and market conditions. The final determination of such dividends will be subject to approval at the Board of Directors’ meeting and general meeting of shareholders.

In addition, the Company determines its shareholder return in consideration of a comprehensive set of factors including its business performance, investment plans, financial status and prospects, and the Company may make shareholder return in the form of cash or shares in accordance with its articles of incorporation. Cash dividends are determined based on the Company’s consideration of investment needs for its continued future growth as well as its annual business performance and overall cash flow status. In the case of share dividends, the type of the shares to be distributed may be determined pursuant to the resolution of the Company’s general meeting of shareholders, to the extent there are multiple classes of shares outstanding.

The Company distributes annual dividends to shareholders or pledgees registered on its shareholder’s register as of the end of each fiscal year, and the Company distributed an interim dividend as of June 30 pursuant to the resolution of the Board of Directors. In order to further enhance the Company’s policy to provide continual shareholder return and in accordance with the global trend towards stable dividend distribution, the Company adopted a quarterly dividend distribution policy in place of its previous interim dividend distribution policy through the approval of certain amendments to the Company’s articles of incorporation at the 37^th^ General Meeting of Shareholders held on March 25, 2021. On July 22, 2021, the Board of Directors resolved to approve the first quarterly dividends.

Furthermore, the Company repurchases its own shares from time to time to enhance its corporate value in consideration of the market price of the Company’s shares and its financial resources. In 2020 and 2021 to date, the Company purchased approximately Won 500 billion of treasury shares through a trustee. In May 2021, the Company canceled 8,685,568 units of previously acquired treasury shares, which represented 10.76% of the total number of shares issued at the time, to enhance shareholder value.

The Company establishes loss allowances based on the likelihood of recoverability of trade and other receivables based on their aging at the end of the period and past customer default experience for the past three years. With respect to trade receivables relating to wireless telecommunications services, the Company considers the likelihood of recovery based on past customer default experience and the length of default in connection with the type of default (e.g., whether the customer’s service has been terminated or is continued). Consistent with customary practice, the Company writes off trade and other receivables for which the prescription period has passed or that are determined to be impossible or economically too costly to collect, including receivables that are less than Won 200,000 and more than six months overdue and receivables that have been determined to be the subject of identity theft.

2. Overview

In 2021, the Company successfully completed the Spin-off of its ICT portfolio, including its security, commerce and mobility businesses, and engaged in corporate reorganization with the vision of becoming a “fixed-line and wireless telecommunication-based service company.” Consolidated revenue increased by 4.1% from 2020 to Won 16.7 trillion mainly due to an increase in the proportion of the Company’s 5G plan subscribers and steady growth in the number of IPTV and high-speed internet subscribers. Operating profit increased by 11.1% from 2020 to Won 1.4 trillion as a result of increased sales and enhanced cost efficiency.

5G services, which the Company was the first to commercialize in the world in 2019, are propelling the growth of the Company’s wireless business. As of December 31, 2021, the Company secured 9.87 million 5G subscribers and a 47% share of the 5G services market in Korea. As a result, cellular services revenue increased by 3% compared to 2020 despite adverse market conditions, including a decrease in roaming services revenue. The Company is continuing to expand its online distribution channels to promote sustainable growth through its subscription, metaverse and enterprise businesses while adapting to the increasingly contactless social environment in a timely manner.

In the case of the Company’s fixed-line and media business, the Company recorded its best financial results to date primarily due to the synergy achieved from the merger with Tbroad as well as the growth in pay TV subscribers and B2B businesses. In particular, the Company has achieved the highest annual growth in the market in terms of net increase in IPTV subscribers.

The Company also plans to strengthen the competitiveness of its media platform by focusing on securing media content and has started to prepare for future growth in the field of connected intelligence, which adds connectivity and intelligence to various future devices.

7. Discontinued Operations

Pursuant to the resolution of the extraordinary general meeting of shareholders on October 12, 2021, the Company conducted the Spin-off of certain of its operations for the purpose of managing the Company’s equity investments in semiconductor and new ICT companies as well as making new investments relating thereto. The date of the Spin-off transaction was November 1, 2021.

As a result of the Spin-off, the Company discontinued certain of its security, commerce and other businesses, which were transferred to the newly established company. Accordingly, certain of the Company’s material subsidiaries, including One Store Co., Ltd., SK Planet Co., Ltd., Eleven Street Co., Ltd., Dreamus Company, SK shieldus Co., Ltd., Incross, T Map Mobility and SK M&Service Co., Ltd., have become excluded from the Company’s consolidation scope.

See note 42 of the notes to the Company’s audited consolidated financial statements attached hereto for more information on profit and loss from discontinued operations.

8. Corporate Reorganization

•	Corporate reorganization of SK Telecom

As of November 1, 2021, the Company conducted the Spin-off in order to transform into a fixed-line and wireless telecommunication-based “AI & Digital Infrastructure Service Company.”

By introducing the Company-in-Company (“CIC”) systems for business-to-consumers (“B2C”) and B2B businesses that encompass SK Telecom and SK Broadband, the Company plans to maximize the synergy between the two companies’ businesses through an integrated, one-body operation that transcends the boundaries between the two companies. In addition, by introducing the “Chief Office” system, the Company strengthened expertise and responsibility management in each key business segment.

•	Corporate reorganization of SK Broadband

On January 1, 2022, SK Broadband engaged in corporate reorganization and adopted CIC, CO (Company) and CP (Camp) systems.

The former business and marketing division was reorganized into “AI & Customer CIC” for B2C customers and “Enterprise CIC” for B2B customers. Each CIC is composed of a CO, which is a division responsible for unit business, and a CP, which is a specialized marketing division.

The former “Service Headquarter” was renamed “ICT Infra,” and certain divisions were integrated or newly established for organizational efficiency and specialization.

9. Liquidity

Interest coverage ratio (EBITDA divided by interest expense) was 14.8, 13.8 and 12.7 at the end of each of 2021, 2020 and 2019. The Company continues to have sufficient liquidity.

10. Financing

Independent Auditors’ Report

Based on a report originally issued in Korean

To the Board of Directors and Shareholders of

SK Telecom Co., Ltd.:

Opinion

We have audited the accompanying consolidated financial statements of SK Telecom Co., Ltd. and its subsidiaries (the “Group”) which comprise the consolidated statements of financial position as of December 31, 2021 and 2020 and the consolidated statements of income, comprehensive income, changes in equity and cash flows for the years then ended, and notes to the consolidated financial statements, comprising significant accounting policies and other explanatory information.

In our opinion, the accompanying consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Group as of December 31, 2021 and 2020, and its consolidated financial performance and its consolidated cash flows for the years then ended in accordance with Korean International Financial Reporting Standards (“K-IFRS”).

Basis for Opinion

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

Emphasis of Matter

Without qualifying our opinion, we draw attention to the following:

As described in Note 3 and Note 42, pursuant to the resolution of shareholders’ meeting held on October 12, 2021, the SK Telecom Co., Ltd. completed the spin-off of certain businesses on November 1, 2021. The spin-off company will engage in managing investments in semiconductor, New Information and Communication Technologies(“ICT”) and other businesses and making new investments and the surviving company will continue to engage in the remaining businesses of SK Telecom Co., Ltd. and certain subsidiaries, primarily cellular and fixed-line telecommunications businesses. The spin-off businesses are presented as discontinued operations, and the comparative consolidated statements of income and comprehensive income have been re-presented to show the discontinued operations separately from continuing operations.

Key Audit Matters

Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the consolidated financial statements as of and for the year ended December 31, 2021. These matters were addressed in the context of our audit of the consolidated financial statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters.

1.	Revenue Recognition

As described in note 3 (23) and 4 (2) of the consolidated financial statements, the Group’s revenue from cellular services is primarily generated from the provision of a variety of telecommunications services at various rate plans and products. Revenue from wireless service amounted to ~~W~~10,100,368 million in 2021. It is recognized based on data from complex information technology systems that process large volume of transactions with subscribers. Therefore, we have identified revenue recognition related to the Group’s wireless service as a key audit matter due to the complexity of information technology systems involved and the revenue recognition standard applied.

LOGO

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

•	Testing certain internal controls relating to the Group’s revenue recognition process, including information<br>technology (IT) systems used for the purposes of revenue recognition. Specifically, we assessed the IT system environment for data records, rating and billing systems, which aggregate data used for revenue recognition for voice usage, text and<br>mobile data services, generate customer bills and support measurement of revenue.
•	Comparing a sample of revenue transactions to supporting evidence, such as customer billing statements, rating<br>system information, subscriber contracts, and cash received, where applicable.
---	---
•	Inspecting major contracts with subscribers to assess the Group’s revenue recognition policies based on the<br>terms and conditions as set out in the contracts, with reference to the requirements of K-IFRS No. 1115.
---	---
2.	Evaluation of goodwill impairment for the fixed-line telecommunication services cash generating unit
---	---

As described in notes 3 (12) and 16 of the consolidated financial statements, the Group performs impairment test for goodwill at least annually or when there is an indication of possible impairment by comparing the recoverable amount and the carrying amount of a cash generating unit (“CGU”) to which goodwill is allocated. In the Group’s impairment test as of December 31, 2021, the Group does not expect the total carrying amount of the CGU will exceed the value in use (“VIU”) due to reasonably possible changes in certain assumptions. The amount of goodwill that is allocated to the fixed-line telecommunication services CGU is ~~W~~764,082 million as of December 31, 2021.

In carrying out the impairment assessment of goodwill, management determined the recoverable amount based on the value in use (“VIU”). Determining the VIU of the fixed-line telecommunication services CGU involves significant judgments in estimating the expected future cash flows including the estimates of future operating revenue, perpetual growth rate and discount rate. We have identified the evaluation of goodwill impairment in the fixed-line telecommunication services CGU as a key audit matter due to the uncertainty of and the significance of the impact of assumptions applied in determining the recoverable amount.

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

•	Involving our internal valuation professionals to assist us in evaluating estimated future operating revenue and<br>perpetual growth rate by comparison with industry reports as well as historical performance and evaluating the discount rate by comparing with the discount rate that was independently developed using publicly available market data for comparable<br>entities.
•	Performing sensitivity analysis for both the discount rate and the perpetual growth rate applied to the<br>discounted cash flow forecasts to assess the impact of changes in these key assumptions on the conclusion reached in management’s impairment assessment.
---	---
•	Evaluating estimated operating revenue by comparison with the financial budgets approved by the Group and<br>comparing the cash flow forecasts prepared in prior year with the actual results to assess the Group’s ability to accurately forecast.
---	---

Other Matter

The procedures and practices utilized in the Republic of Korea to audit such consolidated financial statements may differ from those generally accepted and applied in other countries.

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

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

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

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

Auditors’ Responsibilities for the Audit of the Consolidated Financial Statements

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

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

•	Identify and assess the risks of material misstatement of the consolidated financial statements, whether due to<br>fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is<br>higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.
•	Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are<br>appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Group’s internal control.
---	---
•	Evaluate the appropriateness of accounting policies used in the preparation of the consolidated financial<br>statements and the reasonableness of accounting estimates and related disclosures made by management.
---	---
•	Conclude on the appropriateness of management’s use of the going concern basis of accounting and, based on<br>the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Group’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are<br>required to draw attention in our auditors’ report to the related disclosures in the consolidated financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to<br>the date of our auditors’ report. However, future events or conditions may cause the Group to cease to continue as a going concern.
---	---
•	Evaluate the overall presentation, structure and content of the consolidated financial statements, including the<br>disclosures, and whether the consolidated financial statements represent the underlying transactions and events in a manner that achieves fair presentation.
---	---
•	Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business<br>activities within the Group to express an opinion on the consolidated financial statements. We are responsible for the direction, supervision and performance of the group audit. We remain solely responsible for our audit opinion.<br>
---	---

LOGO

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

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

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

The engagement partner on the audit resulting in this independent auditors’ report is In Hye Kang.

Notes to the Consolidated Financial Statements

For the years ended December 31, 2021 and 2020

2.	Basis of Preparation

These consolidated financial statements were prepared in accordance with Korean International Financial Reporting Standards (“K-IFRS”), as prescribed in the Act on External Audits of Stock Companies, Etc. in the Republic of Korea.

The accompanying consolidated financial statements comprise the Group and the Group’s investments in associates and joint ventures.

The consolidated financial statements were authorized for issuance by the Board of Directors on February 8, 2022, which will be submitted for approval at the shareholders’ meeting to be held on March 25, 2022.

(1)	Basis of measurement

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

•	derivative financial instruments measured at fair value;
•	financial instruments measured at fair value through profit or loss (“FVTPL”);
---	---
•	financial instruments measured at fair value through other comprehensive income (“FVOCI”);<br>
---	---
•	liabilities (assets) for defined benefit plans recognized at the total present value of defined benefit<br>obligations less the net of the fair value of plan assets
---	---
(2)	Functional and presentation currency
---	---

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

(3)	Use of estimates and judgments

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

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

1)	Critical judgments

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

(3)	Use of estimates and judgments, Continued
---	---
2)	Assumptions and estimation uncertainties
---	---

Information about assumptions and estimation uncertainties that have a significant risk of resulting in a material adjustment within the next financial year are included in the following notes: loss allowance (notes 6 and 36), estimated useful lives of costs to obtain a contract (notes 7), property and equipment and intangible assets (notes 3 (7), (9), 13 and 17), impairment of goodwill (notes 3 (12) and 16), recognition of provision (notes 3 (17) and 20), measurement of defined benefit liabilities (notes 3 (16) and 21), transaction of derivative instruments (notes 3 (6) and 22) and recognition of deferred tax assets (liabilities) (notes 3 (25) and 32).

3)	Fair value measurement

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

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

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

•	Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities;<br>
•	Level 2: inputs other than quoted prices included in Level 1 that are observable for the asset or<br>liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices); and
---	---
•	Level 3: inputs for the asset or liability that are not based on observable market data (unobservable<br>inputs).
---	---

If the inputs used to measure the fair value of an asset or a liability fall into different levels of the fair value hierarchy, then the fair value measurement is categorized in its entirety in the same level of the fair value hierarchy as the lowest level input that is significant to the entire measurement. The Group recognizes transfers between levels of the fair value hierarchy at the end of the reporting period during which the change has occurred.

Information about assumptions used for fair value measurements are included in note 22 and note 36.

•	when the basis of determining the contractual cash flows of a financial asset or financial liability measured at<br>amortized cost changed as a result of interest rate benchmark reform (“IBOR reform”), the Group updates the effective interest rate of the financial asset or financial liability rather than the carry amount and,
•	when the basis for determining the contractual cash flows of the hedged item or hedging instrument changes as a<br>result of the IBOR reform, the exception permits the hedge relationship to be continued while the Group amends the hedge documentation of that hedging relationship to reflect the changes required by IBOR reform.
---	---

These amended standards are not expected to have a significant impact on the Group’s consolidated financial statements.

Meanwhile, as described in note 42, the Parent Company carried out spin-off of its business of managing investments in semiconductor, New Information and Communication Technologies(“ICT”) and other businesses and making new investments pursuant to the resolution of the Board of Directors on June 10, 2021 and approval of shareholders’ meeting on October 12, 2021. The Group has applied K-IFRS No. 1105, Non-current assets held for sale and discontinued operations, and accordingly, presented profit or loss of the spin-off business as discontinued operations. The comparative consolidated statements of income and comprehensive income have been re-presented to show the discontinued operations separately from continuing operations.

(1)	Operating segments

An operating segment is a component of the Group that engages in business activities from which it may earn revenues and incur expenses, including revenues and expenses that relate to transactions with any of the Group’s other components. The Group’s operating segments have been determined to be each business unit, for which the Group generates separately identifiable financial information that is regularly reported to the chief operating decision maker for the purpose of resource allocation and assessment of segment performance. The Group has three reportable segments as described in note 4. Segment results that are reported to the chief operating decision maker include items directly attributable to a segment as well as those that can be allocated on a reasonable basis.

(2)	Basis of consolidation
---	---
1)	Business combination
---	---

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

In determining whether a particular set of activities and assets is a business, the Group assesses whether the set of assets and activities acquired includes, at a minimum, an input and substantive process and whether the acquired set has the ability to produce outputs.

The Group has an option to apply a ‘concentration test’ that permits a simplified assessment of whether an acquired set of activities and assets is not a business. The optional concentration test is met if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets.

Consideration transferred is generally measured at fair value, identical to the measurement of identifiable net assets acquired at fair value. The difference between the acquired company’s fair value and the consideration transferred is accounted for goodwill. Any goodwill that arises is tested annually for impairment. Any gain on a bargain purchase is recognized in profit or loss immediately. Acquisition- related costs are expensed in the periods in which the costs are incurred and the services are received, except if related to the costs to issue debt or equity securities recognized based on K-IFRS No. 1032 and K-IFRS No. 1109.

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

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

2) Non-controlling interests

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

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

3)	Subsidiaries

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

---	---
4)	Loss of control
---	---

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

5)	Interest in investees accounted for using the equity method

Interest in investees accounted for using the equity method composed of interest in associates and joint ventures.

An associate is an entity in which the Group has significant influence, but not control, over the entity’s financial and operating policies. A joint venture is a joint arrangement whereby the Group that has joint control of the arrangement has rights to the net assets of the arrangement.

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

6)	Intra-group transactions

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

7)	Business combinations under common control

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

(3)	Cash and cash equivalents

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

(4)	Inventories

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

(5)	Non-derivative financial assets
---	---
1)	Recognition and initial measurement
---	---

Accounts receivable – trade and debt investments issued are initially recognized when they are originated. All other financial assets and financial liabilities are initially recognized when the Group becomes a party to the contractual provisions of the instrument.

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

2)	Classification and subsequent measurement

On initial recognition, a financial asset is classified as measured at:

•	FVTPL
•	FVOCI – equity investment
---	---
•	FVOCI – debt investment
---	---
•	Financial assets at amortized cost
---	---

A financial asset is classified based on the business model in which a financial asset is managed and its contractual cash flow characteristics.

Financial assets are not reclassified subsequent to their initial recognition unless the Group changes its business model for managing financial assets, in which case all affected financial assets are reclassified on the first day of the first reporting period following the change in the business model.

A financial asset is measured at amortized cost if it meets both of the following conditions and is not designated as at FVTPL:

•	it is held within a business model whose objective is to hold assets to collect contractual cash flows; and<br>
•	its contractual terms give rise to cash flows that are solely payments of principal and interest on the principal<br>amount outstanding on specified dates.

2)	Classification and subsequent measurement, Continued
---	---

A debt investment is measured at FVOCI if it meets both of the following conditions and is not designated as at FVTPL:

•	it is held within a business model whose objective is achieved by both collecting contractual cash flows and<br>selling financial assets; and
•	its contractual terms give rise to cash flows that are solely payments of principal and interest on the principal<br>amount outstanding on specified dates.
---	---

On initial recognition of an equity investment that is not held for trading, the Group may irrevocably elect to present subsequent changes in the investment’s fair value in other comprehensive income (“OCI”). This election is made on an investment-by-investment basis.

All financial assets not classified as measured at amortized cost or FVOCI as described above are measured at FVTPL. This includes all derivative financial assets. On initial recognition, the Group may irrevocably designate a financial asset that otherwise meets the requirements to be measured at amortized cost or at FVOCI as at FVTPL if doing so eliminates or significantly reduces an accounting mismatch that would otherwise arise.

The following accounting policies are applied to the subsequent measurement of financial assets.

Financial assets at FVTPL	These assets are subsequently measured at fair value. Net gains and losses, including any interest or dividend income, are recognized in profit or loss.
Financial assets at amortized cost	These assets are subsequently measured at amortized cost using the effective interest method. The amortized cost is reduced by impairment losses. Interest income, foreign exchange gains and losses and impairment are recognized in<br>profit or loss. Any gain or loss on derecognition is recognized in profit or loss.
Debt investments at FVOCI	These assets are subsequently measured at fair value. Interest income calculated using the effective interest method, foreign exchange gains and losses and impairment are recognized in profit or loss. Other net gains and losses are<br>recognized in OCI. On derecognition, gains and losses accumulated in OCI are reclassified to profit or loss.
Equity investments at FVOCI	These assets are subsequently measured at fair value. Dividends are recognized as income in profit or loss unless the dividend clearly represents a recovery of the cost of the investment. Other net gains and losses are recognized in<br>OCI and are never reclassified to profit or loss.

3)	Impairment
---	---

The Group estimates the expected credit losses (“ECL”) for the debt instruments measured at amortized cost and FVOCI based on the Group’s historical experience and informed credit assessment that includes forward-looking information. The impairment approach is decided based on the assessment of whether the credit risk of a financial asset has increased significantly since initial recognition. However, the Group applies a practical expedient and recognizes impairment losses equal to lifetime ECLs for accounts receivable – trade and lease receivables from the initial recognition.

ECL is a probability-weighted estimate of credit losses. Credit losses are measured as the present value of all cash shortfalls (i.e. the difference between the cash flows due to the entity in accordance with the contract and the cash flows that the Group expects to receive).

At each reporting date, the Group assesses whether financial assets measured at amortized cost and debt investments at FVOCI are credit-impaired. A financial asset is ‘credit-impaired’ when one or more events that have a detrimental impact on the estimated future cash flows of the financial asset have occurred.

Loss allowance on financial assets measured at amortized cost is deducted from the carrying amount of the respective assets, while loss allowance on debt instruments at FVOCI is recognized in OCI, instead of reducing the carrying amount of the transferred assets.

4)	Derecognition
Financial	assets
---	---

The Group derecognizes a financial asset when:

•	the contractual rights to the cash flows from the financial asset expire; or
•	it transfers the rights to receive the contractual cash flows in a transaction in which either:<br>
---	---
•	substantially all of the risks and rewards of ownership of the financial asset are transferred; or<br>
---	---
•	the Group neither transfers nor retains substantially all of the risks and rewards of ownership and it does not<br>retain control of the financial asset.
---	---

The Group enters into transactions whereby it transfers assets recognized in its consolidated statement of financial position, but retains either all or substantially all of the risks and rewards of the transferred assets. In these cases, the transferred assets are not derecognized.

Interest rate benchmark reform

When the basis for determining the contractual cash flows of a financial asset or financial liability measured at amortized cost changed as a result of interest rate benchmark reform, the Group updated the effective interest rate of the financial asset or financial liability to reflect the change that is required by the reform. A change in the basis for determining the contractual cash flows is required by interest rate benchmark reform if the following conditions are met:

•	the change is necessary as a direct consequence of the reform; and
•	the new basis for determining the contractual cash flows is economically equivalent to the previous basis –<br>i.e. the basis immediately before the change.
---	---

When changes were made to a financial asset or financial liability in addition to changes to the basis for determining the contractual cash flows required by interest rate benchmark reform, the Group first updated the effective rate of the financial asset or financial liability to reflect the change that is required by interest rate benchmark reform. After that, the Group applied the policies on accounting for modifications to the additional changes.

5)	Offsetting

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

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

(6)	Derivative financial instruments, including hedge accounting

Derivatives are initially recognized at fair value. Subsequent to initial recognition, derivatives are measured at fair value at the end of each reporting period, and changes therein are accounted for as described below.

1)	Hedge accounting

The Group holds forward exchange contracts, interest rate swaps, currency swaps and other derivative contracts to manage interest rate risk and foreign exchange risk. The Group designates derivatives as hedging instruments to hedge the variability in cash flow associated with highly probable forecasted transactions or firm commitments (a cash flow hedge).

On initial designation of the hedge, the Group formally documents the relationship between the hedging instrument(s) and hedged item(s), including the risk management objectives and strategy in undertaking the hedge transaction, together with the methods that will be used to assess the effectiveness of the hedging relationship.

Hedges directly affected by interest rate benchmark reform

When uncertainty arises about the interest rate benchmark designated as a hedged risk and the timing or the amount of the interest rate benchmark-based cash flows of the hedged item or of the hedging instrument as a result of IBOR reform, for the purpose of evaluating whether there is an economic relationship between the hedged items and the hedging instruments, the Group assumes that the interest rate benchmark on which the hedged items and the hedging instruments are based is not altered as a result of interest rate benchmark reform.

For a cash flow hedge of a forecast transaction, the Group assumes that the benchmark interest rate will not be altered as a result of interest rate benchmark reform for the purpose of assessing whether the forecast transaction is highly probable and determining whether a previously designated forecast transaction in a discontinued cash flow hedge is still expected to occur.

The Group will cease applying the specific policy for assessing the economic relationship between the hedged item and the hedging instrument

•	to a hedged item or hedging instrument when the uncertainty arising from interest rate benchmark reform is no<br>longer present with respect to the timing and the amount of the interest rate benchmark-based cash flows of the respective item or instrument; or
•	when the hedging relationship is discontinued.
---	---

When the basis for determining the contractual cash flows of the hedged item or hedging instrument changes as a result of IBOR reform and therefore there is no longer uncertainty arising about the cash flows of the hedged item or the hedging instrument, the Group amends the hedge documentation of that hedging relationship to reflect the change(s) required by IBOR reform.

The Group amends the formal hedge documentation by the end of the reporting period during which a change required by IBOR reform is made to the hedged risk, hedged item or hedging instrument. These amendments in the formal hedge documentation do not constitute the discontinuation of the hedging relationship or the designation of a new hedging relationship.

If changes are made in addition to those changes required by interest rate benchmark reform to the financial asset or financial liability designated in a hedging relationship or to the designation of the hedging relationship, the Group determines whether those additional changes result in the discontinuation of hedging accounting. If the additional changes do not result in the discontinuation of hedging accounting, the Group amend the formal designation of the hedging relationship.

When the interest rate benchmark on which the hedged future cash flows had been based is changed as required by IBOR reform, for the purpose of determining whether the hedged future cash flows are expected to occur, the Group deems that the hedging reserve recognized in OCI for that hedging relationship is based on the alternative benchmark rate on which the hedged future cash flows will be based.

Cash flow hedge

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

2)	Other derivative financial instruments

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

(7)	Property and equipment
---	---

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

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

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

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

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

The estimated useful lives of the Group’s property and equipment are as follows:

	Useful lives (years)
Buildings and structures	15 ~ 40
Machinery	3 ~ 15, 30
Other property and equipment	3 ~10

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

(8)	Borrowing costs
---	---

The Group capitalizes borrowing costs directly attributable to the acquisition, construction or production of a qualifying asset as part of the cost of that asset. Other borrowing costs are recognized in expense as incurred. A qualifying asset is an asset that requires a substantial period of time to get ready for its intended use or sale. Financial assets are not qualifying assets, and assets that are ready for their intended use or sale when acquired are not qualifying assets either.

To the extent that the Group borrows funds specifically for the purpose of obtaining a qualifying asset, the Group determines the amount of borrowing costs eligible for capitalization as the actual borrowing costs incurred on that borrowing during the period less any investment income on the temporary investment of those borrowings. To the extent that the Group borrows funds generally and uses them for the purpose of obtaining a qualifying asset, the Group determines the amount of borrowing costs eligible for capitalization by applying a capitalization rate to the expenditures on that asset. The capitalization rate is the weighted average of the borrowing costs applicable to the borrowings of the Group that are outstanding during the period other than borrowings made specifically for the purpose of obtaining a qualifying asset. The amount of borrowing costs that the Group capitalizes during a period do not exceed the amount of borrowing costs incurred during the period.

(9)	Intangible assets

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

Intangible assets, except for goodwill, are amortized on a straight-line basis over the estimated useful lives of intangible assets from the date that they are available for use. The residual value of intangible assets is zero. However, club memberships and brand are expected to be available for use as there are no foreseeable limits to the periods. These intangible assets are determined as having indefinite useful lives and, therefore, not amortized.

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

	Useful lives (years)
Frequency usage rights	2.9 ~ 10
Land usage rights	5
Industrial rights	5, 10
Development costs	5
Facility usage rights	10, 20
Customer relations	3 ~ 15
Other	3 ~ 20

Amortization periods and the amortization methods for intangible assets with finite useful lives are reviewed at the end of each reporting period. The useful lives of intangible assets that are not being amortized are reviewed at the end of each reporting period to determine whether events and circumstances continue to support indefinite useful life assessments for those assets. Changes, if appropriate, are accounted for as changes in accounting estimates.

Expenditures on research activities are recognized in profit or loss as incurred. Development expenditures are capitalized only if development costs can be reliably measured, the product or process is technically and commercially feasible, future economic benefits are probable, and the Group intends to and has sufficient resources to complete development and to use or sell the asset. Other development expenditures are recognized in profit or loss as incurred.

Subsequent expenditures are capitalized only when they increase the future economic benefits embodied in the specific asset to which it relates. All other expenditures, including expenditures on internally generated goodwill and brands, are recognized in profit or loss as incurred.

(10)	Government grants

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

1)	Grants related to assets

Government grants whose primary condition is that the Group purchases, constructs, or otherwise acquires a long-term asset are deducted in calculating the carrying amount of the asset. The grant is recognized in profit or loss over the life of a depreciable asset as a reduction to depreciation expense.

2)	Grants related to income

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

(11)	Investment property

Investment properties are properties held to earn rentals and/or for capital appreciation. Investment properties are measured initially at cost, including transaction costs. Subsequent to initial recognition, investment properties are reported at cost less accumulated depreciation and accumulated impairment losses.

Subsequent expenditures are recognized in carrying amount of an asset or as a separate asset if it is probable that future economic benefits associated with the assets will flow into the Group and the cost of an asset can be measured reliably. The carrying amount of those parts that are replaced is derecognized. The costs associated with routine maintenance and repairs are recognized in profit or loss as incurred.

Investment property, except for land, is depreciated on a straight-line basis over estimated useful lives of 30 years. In addition, right-of-use asset classified as investment property is depreciated using the straight-line basis from the commencement date to the end of the lease term.

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

(12)	Impairment of non-financial assets
---	---

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

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

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

Goodwill acquired in a business combination is allocated to each CGU that is expected to benefit from the synergy arising from the business acquired. Any impairment identified at the CGU level will first reduce the carrying amount of goodwill and then be used to reduce the carrying amount of the other assets in the CGU on a pro rata basis. Except for impairment losses in respect of goodwill which are never reversed, an impairment loss is reversed if there has been a change in the estimates used to determine the recoverable amount. An impairment loss is reversed only to the extent that the asset’s carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortization, if no impairment loss had been recognized.

(13)	Leases

A contract is or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration.

1)	As a lessee

At commencement or on modification of a contract that contains a lease component, the Group allocates the consideration in the contract to each lease component on the basis of its relative stand-alone prices. However, the Group has elected not to separate non-lease components and account for the lease and non-lease components as a single lease component.

The Group recognizes a right-of-use asset and a lease liability at the lease commencement date. The right-of-use asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for any lease payments made at or before the commencement date, plus any initial direct costs incurred and an estimate of costs to dismantle and remove the underlying asset or to restore the underlying asset or the site on which it is located, less any lease incentives received.

---	---

The right-of-use asset is subsequently depreciated using the straight-line basis from the commencement date to the end of the lease term, unless the lease transfers ownership of the underlying asset to the Group by the end of the lease term or the cost of the right-of-use asset reflects that the Group will exercise a purchase option. In that case the right-of-use asset will be depreciated over the useful life of the underlying asset, which is determined on the same basis as those of property and equipment. In addition, the right-of-use asset is periodically reduced by impairment losses, if any, and adjusted for certain remeasurements of the lease liability.

The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the Group’s incremental borrowing rate. Generally, the Group uses its incremental borrowing rate as the discount rate.

The Group determines its incremental borrowing rate by obtaining interest rates from various external financing sources and makes certain adjustments to reflect the terms of the lease and type of the asset leased.

Lease payments included in the measurement of the lease liability comprise the following:

•	fixed payments, including in-substance fixed payments;<br>
•	variable lease payments that depend on an index or a rate, initially measured using the index or rate as at the<br>commencement date;
---	---
•	amounts expected to be payable under a residual value guarantee; and
---	---
•	the exercise price under a purchase option that the Group is reasonably certain to exercise, lease payments in an<br>optional renewal period if the Group is reasonably certain to exercise an extension option, and penalties for early termination of a lease unless the Group is reasonably certain not to terminate early.
---	---

The lease liability is measured at amortized cost using the effective interest method. It is remeasured when there is a change in future lease payments arising from a change in an index or rate, if there is a change in the Group’s estimate of the amount expected to be payable under a residual value guarantee, if the Group changes its assessment of whether it will exercise a purchase, extension of termination option of if there is a revised in-substance fixed lease payment.

When the lease liability is remeasured in this way, a corresponding adjustment is made to the carrying amount of the right-of-use asset, or is recorded in profit or loss if the carrying amount of the right-of-use asset has been reduced to zero.

The Group presents right-of-use assets that do not meet the definition of investment property in ‘property and equipment’ in the statement of financial position.

The Group has elected not to recognize right-of-use assets and lease liabilities for leases of low-value assets and short-term leases. The Group recognizes the lease payments associated with lease as an expense on a straight-line basis over the lease term.

(13)	Leases, Continued
---	---
2)	As a lessor
---	---

At inception or on modification of a contract that contains a lease component, the Group allocates the consideration in the contract to each lease component on the basis of their relative stand-alone prices.

When the Group acts as a lessor, it determines at lease inception whether each lease is a finance lease or an operating lease.

To classify each lease, the Group makes an overall assessment of whether the lease transfers substantially all of the risks and rewards incidental to ownership of the underlying asset. If this is the case, then the lease is a finance lease; if not, then it is an operating lease. As part of this assessment, the Group considers certain indicators such as whether the lease is for the major part of the economic life of the asset.

When the Group is an intermediate lessor, is accounts for its interests in the head lease and the sub- lease separately. It assesses the lease classification of a sub-lease with reference to the right-of-use asset arising from the head lease, not with reference to the underlying asset. If a head lease is a short-term lease to which the Group applies the exemption described above, then it classifies the sub-lease as an operating lease.

If an arrangement contains lease and non-lease components, then the Group applies K-IFRS No. 1115 to allocate the consideration in the contract.

The Group applies derecognition and impairment requirements in K-IFRS No. 1109 to the net investment in the lease. The Group further regularly reviews estimated unguaranteed residual values used in calculating the gross investment in the lease.

The Group recognizes lease payments received under operating leases as income on a straight-line basis over the lease term as part of ‘other revenue’.

(14)	Non-current assets held for sale

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

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

(15)	Non-derivative financial liabilities
---	---

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

1)	Financial liabilities at fair value through profit or loss

Financial liabilities at fair value through profit or loss include financial liabilities held for trading or designated as such upon initial recognition. Subsequent to initial recognition, these liabilities are measured at fair value. The amount of change in fair value of financial liability that is attributable to changes in the credit risk of that liability shall be presented in other comprehensive income, and the remaining amount of change in the fair value of the liability shall be presented in profit or loss. Upon initial recognition, transaction costs that are directly attributable to the issue of the financial liability are recognized in profit or loss as incurred.

2)	Other financial liabilities

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

3)	Derecognition of financial liability

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

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

(16)	Employee benefits
---	---
1)	Short-term employee benefits
---	---

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

2)	Other long-term employee benefits

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

3)	Retirement benefits: defined contribution plans

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

4)	Retirement benefits: defined benefit plans

At the end of reporting period, defined benefit liabilities relating to defined benefit plans are recognized at present value of defined benefit obligations net of fair value of plan assets.

The calculation is performed annually by an independent actuary using the projected unit credit method. When the fair value of plan assets exceeds the present value of the defined benefit obligation, the Group recognizes an asset, to the extent of the present value of any economic benefits available in the form of refunds from the plan or reduction in the future contributions to the plan.

Remeasurements of the net defined benefit liability (asset), which comprise actuarial gains and losses, the return on plan assets (excluding interest) and the effect of the asset ceiling (if any, excluding interest), are recognized immediately in other comprehensive income. The Group determines net interests on net defined benefit liability (asset) by multiplying discount rate determined at the beginning of the annual reporting period and considers changes in net defined benefit liability (asset) from contributions and benefit payments. Net interest costs and other costs relating to the defined benefit plan are recognized through profit or loss.

When the plan amendment or curtailment occurs, gains or losses on amendment or curtailment in benefits for the past service provided are recognized through profit or loss. The Group recognizes a gain or loss on a settlement when the settlement of defined benefit plan occurs.

5)	Termination benefits
---	---

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

(17)	Provisions

Provisions are recognized when the Group has a present legal or constructive obligation as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation, and a reliable estimate can be made of the amount of the obligation.

The risks and uncertainties that inevitably surround many events and circumstances are taken into account in reaching the best estimate of a provision. If the effect of the time value of money is material, provisions are determined at the present value of the expected future cash flows.

If some or all of the expenditures required to settle a provision are expected to be reimbursed by another party, the reimbursement is recognized when, and only when, it is virtually certain that reimbursement will be received if the entity settles the obligation. The reimbursement is treated as a separate asset.

Provisions are reviewed at the end of each reporting period and adjusted to reflect the current best estimates. If it is no longer probable that an outflow of resources embodying economic benefits will be required to settle the obligation, the provision is reversed.

A provision is used only for expenditures for which the provision was originally recognized.

(18)	Emissions Rights
---	---

The Group accounts for greenhouse gases emission right and the relevant liability as below pursuant to the Act on Allocation and Trading of Greenhouse Gas Emission in Korea.

1)	Greenhouse Gases Emission Right

Greenhouse Gases Emission Right consists of emission allowances, which are allocated from the government free of charge or purchased from the market. The cost includes any directly attributable costs incurred during the normal course of business.

The Group derecognizes an emission right asset when the emission allowance is unusable, disposed or submitted to government in which the future economic benefits are no longer expected to be probable.

2)	Emissions liability

Emission liability is a present obligation of submitting emission rights to the government with regard to emission of greenhouse gas. The emission liability is measured based on the expected quantity of emission for the performing period in excess of emission allowance in possession and the unit price for such emission rights in the market at the end of the reporting period. The emissions liabilities are derecognized when they are surrendered to the government.

(19)	Transactions in foreign currencies
---	---
1)	Foreign currency transactions
---	---

Transactions in foreign currencies are translated to the functional currency of the Group at exchange rates at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are retranslated to the functional currency using the exchange rate at the reporting date. Non-monetary assets and liabilities denominated in foreign currencies that are measured at fair value are retranslated to the functional currency at the exchange rate at the date that the fair value was determined.

Exchange differences arising from monetary items except for financial liabilities designated cashflow hedging instruments are recognized in profit or loss. If a gain or loss on a non-monetary item is recognized in other comprehensive income, any foreign exchange differences are also recognized in other comprehensive income. When a gain or loss on a non-monetary item is recognized in profit or loss, any foreign exchange differences are also recognized in profit or loss.

2)	Foreign operations

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

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

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

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

(20)	Share capital

Ordinary shares are classified as equity. Incremental costs directly attributable to the issuance of ordinary shares and share options are recognized as a deduction from equity, net of any tax effects.

When the Parent Company repurchases its own shares, the amount of the consideration paid is recognized as a deduction from equity and classified as treasury shares. The gains or losses from the purchase, disposal, reissue, or retirement of treasury shares are directly recognized in equity being as transaction with owners.

(21)	Hybrid bond
---	---

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

(22)	Share-based payment

For equity-settled share-based payment transaction, if the fair value of the goods or services received cannot be reliably estimated, the Group measures the value indirectly by reference to the fair value of the equity instruments granted. The related expense with a corresponding increase in capital surplus and others is recognized over the vesting period of the awards.

The amount recognized as an expense is adjusted to reflect the number of awards for which the related service and non-market performance conditions are expected to be met, such that the amount ultimately recognized is based on the number of awards that meet the related service and non-market performance conditions at the vesting date.

The fair value of the amount payable to employees in respect of share appreciation rights, which are settled in cash, is recognized as an expense with a corresponding increase in liabilities, over the period in which the employees become unconditionally entitled to payment. The liability is remeasured at each reporting date and at settlement date based on the fair value of the share appreciation rights. Any changes in the fair value of the liability are recognized in profit or loss.

(23)	Revenue
1)	Identification of performance obligations in contracts with customers
---	---

The Group identifies the distinct services or goods as performance obligations in contracts with customers such as (1) providing wireless and fixed-line telecommunications services, (2) sale of handsets and (3) providing other goods and services. In the case of providing both wireless telecommunications service and selling a handset together to one customer, the Group allocates considerations from the customer between the separate performance obligations for handset sale and wireless telecommunications service. The handset sale revenue is recognized when handset is delivered, and the wireless telecommunications service revenue is recognized over the period of the contract term as stated in the subscription contract.

2)	Allocation of the transaction price to each performance obligation

The Group allocates the transaction price of a contract to each performance obligation identified on a relative stand-alone selling price basis. The Group uses “adjusted market assessment approach” for estimating the stand-alone selling price of a good or service.

3)	Incremental costs of obtaining a contract

The Group pays commissions to its retail stores and authorized dealers in connection with acquiring service contracts. The commissions paid to these parties constituted a significant portion of the Group’s operating expenses. These commissions would not have been paid if there have been no binding contracts with subscribers and, therefore, the Group capitalizes certain costs associated with commissions paid to obtain new customer contracts and amortize them over the expected contract periods.

4)	Customer loyalty programs
---	---

The Group provides customer loyalty points to customers based on the usage of the service to which the Group allocates a portion of consideration received as a performance obligation distinct from wireless telecommunications services. The amount to be allocated to the loyalty program is measured according to the relative stand-alone selling price of the customer loyalty points. The amount allocated to the loyalty program is deferred as a contract liability and is recognized as revenue when loyalty points are redeemed.

5)	Consideration payable to a customer

Based on the subscription contract, a customer who uses the Group’s wireless telecommunications services may receive a discount for purchasing goods or services from a designated third party. The Group pays a portion of the price discounts that the customer receives to the third party which is viewed as consideration payable to a customer. The Group accounts for the amounts payable to the third party as a reduction of the wireless telecommunications service revenue.

(24)	Finance income and finance costs

Finance income comprises interest income on funds invested (including financial assets measured at fair value), dividend income, gains on disposal of financial assets at FVTPL, changes in fair value of financial instruments at FVTPL, and gains on hedging instruments that are recognized in profit or loss. Interest income is recognized as it accrues in profit or loss, using the effective interest rate method. Dividend income is recognized in profit or loss when the right to receive the dividend is established.

Finance costs comprise interest expense on borrowings, changes in fair value of financial instruments at FVTPL, and losses on hedging instruments that are recognized in profit or loss. Interest expense on borrowings and debentures is recognized as it accrues in profit or loss using the effective interest rate method.

(25)	Income taxes

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

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

1)	Current tax

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

---	---
2)	Deferred tax
---	---

Deferred tax is recognized by using the asset-liability method in respect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. The Group recognizes a deferred tax liability for all taxable temporary differences, except for the difference associated with investments in subsidiaries and associates that the Group is able to control the timing of the reversal of the temporary difference and it is probable that the temporary difference will not reverse in the foreseeable future. The Group recognizes a deferred tax asset for all deductible temporary differences to the extent that it is probable that the temporary difference will reverse in the foreseeable future and taxable profit will be available against which the temporary difference can be utilized.

A deferred tax asset is recognized for the carryforward of unused tax losses and unused tax credits to the extent that it is probable that future taxable profit will be available against which the unused tax losses and unused tax credits can be utilized. Future taxable profit is dependent on the reversal of taxable temporary differences. If there are insufficient taxable temporary differences to recognize the deferred tax asset, the business plan of the Group and the reversal of existing temporary differences are considered in determining the future taxable profit.

The Group reviews the carrying amount of a deferred tax asset at the end of each reporting period and reduces the carrying amount to the extent that it is no longer probable that sufficient taxable profit will be available to allow the benefit of part or all of that deferred tax asset to be utilized.

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the period when the asset is realized, or the liability is settled based on tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period. The measurement of deferred tax liabilities and deferred tax assets reflects the tax consequences that would follow from the manner in which the Group expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities.

Deferred tax assets and liabilities are offset only if the Group has a legally enforceable right to offset the amount recognized and intends to settle the current tax liabilities and assets on a net basis. Income tax expense in relation to dividend payments is recognized when liabilities relating to the dividend payments are recognized.

3)	Uncertainty over income tax treatments

The Group assesses the uncertainty over income tax treatments pursuant to K-IFRS No. 1012. If the Group concludes it is not probable that the taxation authority will accept an uncertain tax treatment, the Group reflects the effect of uncertainty for each uncertain tax treatment by using either of the following methods, depending on which method the entity expects to better predict the resolution of the uncertainty:

•	The most likely amount: the single most likely amount in a range of possible outcomes.
•	The expected value: the sum of the probability-weighted amounts in a range of possible outcomes.<br>

(26)	Earnings per share
---	---

The Group presents basic and diluted earnings per share (EPS) data for its ordinary shares. Basic EPS is calculated by dividing the profit or loss attributable to ordinary shareholders of the Parent Company by the weighted average number of ordinary shares outstanding during the period, adjusted for own shares held. Diluted EPS is determined by adjusting the profit or loss attributable to ordinary shareholders and the weighted average number of ordinary shares outstanding, adjusted for own shares held, for the effects of all dilutive potential ordinary shares, which comprise share options granted to employees, if any.

(27)	Discontinued operation

A discontinued operation is a component of the Group’s business, the operations and cash flows of which can be clearly distinguished from the rest of the Group and which:

•	represents a separate major line of business or geographic area of operations;
•	is part of a single co-ordinated plan to dispose of a separate major line<br>of business or geographic area of operations; or
---	---
•	is a subsidiary acquired exclusively with a view to resale.

When an operation is classified as a discontinued operation, the comparative statements of income and comprehensive income are re-presented as if the operation had been discontinued from the start of the comparative year.

(28)	Standards issued but not yet effective

The following new standards are effective for annual periods beginning after January 1, 2021. The following new and amended standards are not expected to have a significant impact on the Group’s consolidated financial statements.

(1)	Segment information for the years ended December 31, 2021 and 2020 are as follows, Continued:<br>
---	---
(*)	The Parent Company carried out spin-off of its business of managing<br>investments in semiconductor, New Information and Communication Technologies(“ICT”) and other business and making new investments for the year ended December 31, 2021. Accordingly, the Group reclassified SK stoa Co., Ltd. from<br>Commerce Services segment to Others segment.
---	---

The Group has restated the previously reported segment information for the year ended December 31, 2020 to reflect reclassification of operating segments due to spin-off.

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

No single customer contributed 10% or more to the Group’s total revenue for the years ended December 31, 2021 and 2020.

(*1) Includes amounts related to discontinued operations.

(*2)	The Group writes off the trade and other receivables that are determined to be uncollectable due to reasons<br>such as termination of operations or bankruptcy.
(3)	The Group applies the practical expedient that allows the Group to estimate the loss allowance for accounts<br>receivable – trade at an amount equal to the lifetime expected credit losses. The expected credit losses include the forward-looking information. To make the assessment, the Group uses its historical credit loss experience over the past three<br>years and classifies the accounts receivable - trade by their credit risk characteristics and days overdue. Details of loss allowance on accounts receivable – trade as of December 31, 2021 are as follows:
---	---
(In millions of won)
---	---	---	---	---	---	---	---	---	---	---	---	---	---

	Loss allowance		13,789			498			4,382			15,278

As the Group is a wireless and fixed-line telecommunications service provider, the Group’s financial assets measured at amortized cost primarily consist of receivables from numerous individual customers, and, therefore, no significant credit concentration risk arises.

Receivables related to other revenue mainly consist of receivables from corporate customers. The Group transacts only with corporate customers with credit ratings that are considered to be low at credit risk. In addition, the Group is not exposed to significant credit concentration risk as the Group regularly assesses their credit risk by monitoring their credit rating. While the contract assets are under the impairment requirements, no significant credit risk has been identified.

(2)	Details of the impairment testing of Goodwill as of December 31, 2021 is as follows:<br>
---	---

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

•	goodwill related to Shinsegi Telecom, Inc.(*1): Cellular services;
•	goodwill related to SK Broadband Co., Ltd.(*2): Fixed-line telecommunication services; and
---	---
•	other goodwill: Others.
---	---
(*1)	Goodwill related to merger of Shinsegi Telecom, Inc.
---	---

The recoverable amount of the CGU is based on its value in use calculated by applying the post-tax annual discount rate of 6.6% (2020: 6.3%) (pre-tax annual discount rate: 9.0%) to the estimated future post-tax cash flows based on financial budgets for the next five years. An annual growth rate of 0.5% (2020: (-)0.2%) was applied for the cash flows expected to be incurred after five years and is not expected to exceed the long-term wireless telecommunication industry growth rate. Management of the Group does not expect the total carrying amount of the CGU will exceed the total recoverable amount due to reasonably possible changes from the major assumptions used to estimate the recoverable amount.

(*2)	Goodwill related to acquisition of SK Broadband Co., Ltd.

The recoverable amount of the CGU is based on its value in use calculated by applying the post-tax annual discount rate of 7.1% (2020: 6.9%) (pre-tax annual discount rate: 9.2%) to the estimated future post-tax cash flows based on financial budgets for the next five years. An annual growth rate of 1.0% (2020: 1.0%) was applied for the cash flows expected to be incurred after five years and is not expected to exceed the long-term fixed-line telecommunication industry growth rate. Management of the Group does not expect the total carrying amount of the CGU will exceed the total recoverable amount due to reasonably possible changes from the major assumptions used to estimate the recoverable amount.

The Group is exposed to market risk, credit risk and liquidity risk. Market risk is the risk related to the changes in market prices, such as foreign exchange rates and interest rates. The Group implements a risk management system to monitor and manage these specific risks.

The Group’s financial assets consist of cash and cash equivalents, financial instruments, investment securities, accounts receivable – trade and other, etc. Financial liabilities consist of accounts payable – trade and other, borrowings, debentures, lease liabilities and others.

1)	Market risk
(i)	Currency risk
---	---

The Group incurs exchange position due to revenue and expenses from its global operations. Major foreign currencies where the currency risk occur are USD, EUR and JPY. The Group determines the currency risk management policy after considering the nature of business and the presence of methods that mitigate the currency risk for each Group entities. Currency risk occurs on forecasted transactions and recognized assets and liabilities which are denominated in a currency other than the functional currency of each Group entity. The Group manages currency risk arising from business transactions by using currency forwards, etc.

Monetary assets and liabilities denominated in foreign currencies as of December 31, 2021 are as follows:

In addition, the Group has entered into cross currency swaps to hedge against currency risk related to foreign currency borrowings and debentures. (See note 22)

As of December 31, 2021, a hypothetical change in exchange rates by 10% would have increased (decreased) the Group’s income before income tax as follows:

(ii)	Interest rate risk
---	---

The interest rate risk of the Group arises from borrowings, debentures and long-term payables – other. Since the Group’s interest bearing assets are mostly fixed-interest bearing assets, the Group’s revenue and operating cash flows from the interest-bearing assets are not influenced by the changes in market interest rates.

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

As of December 31, 2021, floating-rate borrowings and debentures amount to ~~W~~37,500 million and ~~W~~355,650 million, respectively, and the Group has entered into interest rate swaps to hedge interest rate risk related to the floating-rate borrowings and debentures as described in note 22. Therefore, income before income taxes for the year ended December 31, 2021 would not have been affected by the changes in interest rates of floating-rate borrowings and debentures.

As of December 31, 2021, the floating-rate long-term payables – other are ~~W~~2,090,715 million. If the interest rate increases (decreases) 1%p with all other variables held constant, income before income taxes for the year ended December 31, 2021, would change by ~~W~~20,907 million in relation to the floating-rate long-term payables - other that are exposed to interest rate risk.

Interest rate benchmark reform and associated risks

A fundamental reform of major interest rate benchmarks is being undertaken globally, including the replacement of some interbank offered rates (IBORs) with alternative nearly risk-free rates (referred to as ‘IBOR reform’). Especially, in the case of LIBOR, all of the calculations were suspended as of December 31, 2021, except for the overnight, one month, three months, six months, and 12 months of USD LIBOR, and the aforementioned five USD LIBORs will also be suspended as of June 30, 2023. The alternative interest rate benchmark of USD LIBOR is the Secured Overnight Financing Rate(“SOFR”). Meanwhile, in case of Korean CD rate, the alternative interest rate benchmark has selected as Korea Overnight Financing Repo Rate(“KOFR”) and as part of interest rate benchmark reform, the interest rate has been disclosed through Korea Securities Depository since November 26, 2021. KOFR is calculated using the overnight RP rate as collateral for government bonds and monetary stabilization bonds. However, unlike LIBOR, calculation of CD rate will not be suspended, it is unclear when and how the transition to KOFR will take place.

The Group plans to include fallback clauses into financial instruments relating to LIBOR to which calculation has not been suspended yet, or change their LIBOR directly to alternative interest rates before the calculation is suspended. Meanwhile, The Group is closely monitoring market trends for CD rate-related financial instruments.

The Group’s financial instruments exposed to the risk arising from interest rate benchmark reform as of December 31, 2021 are indexed to the USD LIBOR. The Group is exposed to legal risk to amend the terms of contracts on the financial instruments subject to interest rate benchmark reform as well as process and operation risks to manage such amendments. In addition, the Group is exposed to the risk of monitoring the market trend regarding the alternative interest rate and establishing the corresponding risk management strategy. If the IBOR is designated as the hedged item, the Group is required to replace it to an alternative benchmark interest and review the effects on the hedging relationship. In addition, the Group is exposed to the risk of minimizing hedge ineffectiveness by aligning the method and timing of the transition to the alternative benchmark interest applied to the hedged item and the hedging instrument.

The Group evaluates the extent to which contracts reference IBOR cash flows, whether such contracts will need to be amended as a result of IBOR reform and how to manage communication about IBOR reform with counterparties.

Non-derivative	financial liabilities

The Parent Company’s non-derivative financial liabilities subject to Interest rate benchmark reform as of December 31, 2020 were floating-rate bonds indexed to USD LIBOR. As explained above, the Group is discussing with the counterparty about including the fallback clauses as of December 31, 2021.

Derivatives

The Group’s most derivative instruments designated as cash flow hedge are governed by contracts based on the International Swaps and Derivatives Association (ISDA)’s master agreements. As part of interest rate benchmark reform, ISDA has included a new fallback clause regarding which alterative benchmark interest rate to be applied when the calculation of major IBOR is suspended in the master agreement. The master agreement is applied to derivative contracts after January 25, 2021 and the transaction parties is required to adhere to ISDA protocol to include the same fallback clause to derivative contracts before January 25, 2021. The Group has adhered to ISDA protocol for transition to the alternative benchmark interest rate and the fallback clause will be included when counterparties adhere to the protocol to include. The Group’s counterparties have adhered to ISDA protocol and agreed to include the fallback clause.

Hedge	accounting

The Group’s hedged items and hedging instruments as of December 31, 2021 are indexed to USD LIBOR. These benchmark rates are quoted each day and the IBOR cash flows are exchanged with counterparties as usual.

The maximum credit exposure as of December 31, 2021 and 2020 are as follows:

(In millions of won)

Cash and cash equivalents	~~W~~	872,550		1,369,423

Credit risk is the risk of financial loss to the Group if a customer or counterparty to a financial instrument fails to meet its contractual obligations. To manage credit risk, the Group evaluates the credit worthiness of each customer or counterparty considering the party’s financial information, its own trading records and other factors. Based on such information, the Group establishes credit limits for each customer or counterparty.

(i)	Accounts receivable – trade and contract assets

The Group establishes a loss allowance in respect of accounts receivable – trade and contract assets. The main components of this allowance are a specific loss component that relates to individually significant exposures and a collective loss component established for groups of similar assets in respect of losses that are expected to occur. The collective loss allowance is determined based on historical data of collection statistics for similar financial assets. Details of changes in loss allowance for the year ended December 31, 2021 are included in note 6.

(ii)	Debt investments

The credit risk arises from debt investments included in ~~W~~509,052 million of financial instruments, ~~W~~2,077 million of investment securities and ~~W~~1,195,917 million of loans and other receivables. To limit the exposure to this risk, the Group transacts only with financial institutions with credit ratings that are considered to be low credit risk.

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

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

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

Fair value of the financial instruments that are traded in an active market (financial assets at FVOCI and financial assets at FVTPL) is measured based on the bid price at the end of the reporting date.

The Group uses various valuation methods for determination of fair value of financial instruments that are not traded in an active market. Derivative financial contracts and long-term liabilities are measured using the discounted present value methods. Other financial assets are determined using the methods such as discounted cash flow and market approach.

Independent Auditors’ Report

Based on a report originally issued in Korean

To the Board of Directors and Shareholders of

SK Telecom Co., Ltd.:

Opinion

We have audited the accompanying separate financial statements of SK Telecom Co., Ltd. (the “Company”) which comprise the separate statements of financial position as of December 31, 2021 and 2020 and the separate statements of income, comprehensive income, changes in equity and cash flows for the years then ended, and notes to the separate financial statements, comprising significant accounting policies and other explanatory information.

In our opinion, the accompanying separate financial statements present fairly, in all material respects, the separate financial position of the Company as of December 31, 2021 and 2020, and its separate financial performance and its separate cash flows for the years then ended in accordance with Korean International Financial Reporting Standards (“K-IFRS”).

We also have audited, in accordance with the Korean Standards on Auditing, the Company’s Internal Control over Financial Reporting as of December 31, 2021, based on the criteria established in Conceptual Framework for Designing and Operating Internal Control over Financial Reporting issued by the Operating Committee of Internal Control over Financial Reporting in the Republic of Korea, and our report dated March 10, 2022 expressed an unmodified opinion on the effectiveness of the Company’s internal control over financial reporting.

Basis for Opinion

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

Emphasis of Matter

Without qualifying our opinion, we draw attention to the following:

As described in Note 41, pursuant to the resolution of shareholders’ meeting held on October 12, 2021, the SK Telecom Co., Ltd. completed the spin-off of certain businesses on November 1, 2021. The spin-off company will engage in managing investments in semiconductor, New Information and Communication Technologies(“ICT”) and other businesses and making new investments and the surviving company will continue to engage in the remaining businesses of SK Telecom Co., Ltd. and certain subsidiaries, primarily cellular and fixed-line telecommunications businesses.

Key Audit Matter

Key audit matter communicated below is a matter that, in our professional judgment, was of most significance in our audit of the separate financial statements as of and for the year ended December 31, 2021. This matter was addressed in the context of our audit of the separate financial statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on this matter.

LOGO

1.	Revenue Recognition

As described in note 3 (23) and 27 of the separate financial statements, the Company’s revenue from cellular services is primarily generated from the provision of a variety of telecommunications services at various rate plans and products. Revenue from wireless service amounted to ~~W~~10,257,440 million in 2021. It is recognized based on data from complex information technology systems that process large volume of transactions with subscribers. Therefore, we have identified revenue recognition related to the Company’s wireless service as a key audit matter due to the complexity of information technology systems involved and the revenue recognition standard applied.

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

•	Testing certain internal controls relating to the Company’s revenue recognition process, including<br>information technology (IT) systems used for the purposes of revenue recognition. Specifically, we assessed the IT system environment for data records, rating and billing systems, which aggregate data used for revenue recognition for voice usage,<br>text and mobile data services, generate customer bills and support measurement of revenue.
•	Comparing a sample of revenue transactions to supporting evidence, such as customer billing statements, rating<br>system information, subscriber contracts, and cash received where applicable.
---	---
•	Inspecting major contracts with subscribers to assess the Company’s revenue recognition policies based on<br>the terms and conditions as set out in the contracts, with reference to the requirements of K-IFRS No. 1115.
---	---

Other Matter

The procedures and practices utilized in the Republic of Korea to audit such separate financial statements may differ from those generally accepted and applied in other countries.

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

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

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

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

LOGO

Auditors’ Responsibilities for the Audit of the Separate Financial Statements

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

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

•	Identify and assess the risks of material misstatement of the separate financial statements, whether due to fraud<br>or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is<br>higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.
•	Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are<br>appropriate in the circumstances.
---	---
•	Evaluate the appropriateness of accounting policies used in the preparation of the separate financial statements<br>and the reasonableness of accounting estimates and related disclosures made by management.
---	---
•	Conclude on the appropriateness of management’s use of the going concern basis of accounting and, based on<br>the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Company’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we<br>are required to draw attention in our auditors’ report to the related disclosures in the separate financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to<br>the date of our auditors’ report. However, future events or conditions may cause the Company to cease to continue as a going concern.
---	---
•	Evaluate the overall presentation, structure and content of the separate financial statements, including the<br>disclosures, and whether the separate financial statements represent the underlying transactions and events in a manner that achieves fair presentation.
---	---

LOGO

From the matters communicated with those charged with governance, we determine this matter that was of most significant in the audit of the separate financial statements of the current period and is therefore the key audit matter. We describe this matter in our auditors’ report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.

The engagement partner on the audit resulting in this independent auditors’ report is In Hye Kang.

2.	Basis of Preparation, Continued

(2) Functional and presentation currency

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

(3) Use of estimates and judgments

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

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

1) Critical judgments

Information about critical judgments in applying accounting policies that have the most significant effects on the amounts recognized in the separate financial statements is included in notes for the following areas: financial risk management.

2) Assumptions and estimation uncertainties

Information about assumptions and estimation uncertainties that have a significant risk of resulting in a material adjustment within the next financial year is included in the following notes: loss allowance (notes 5 and 35), estimated useful lives of costs to obtain a contract (notes 3 (23), and 6), property and equipment and intangible assets (notes 3 (7), (9), 10 and 14), impairment of goodwill (notes 3 (12) and 13), recognition of provision (notes 3 (17) and 17), measurement of defined benefit liabilities (notes 3 (16) and 18), transaction of derivative instruments (notes 3 (6) and 19) and recognition of deferred tax assets (liabilities) (notes 3 (24) and 31).

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

2.	Basis of Preparation, Continued

(3) Use of estimates and judgments, Continued

3) Fair value measurement, Continued

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

•	Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities;<br>
•	Level 2: inputs other than quoted prices included in Level 1 that are observable for the asset or<br>liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices); and
---	---
•	Level 3: inputs for the asset or liability that are not based on observable market data (unobservable inputs).<br>
---	---

If the inputs used to measure the fair value of an asset or a liability fall into different levels of the fair value hierarchy, then the fair value measurement is categorized in its entirety in the same level of the fair value hierarchy as the lowest level input that is significant to the entire measurement. The Company recognizes transfers between levels of the fair value hierarchy at the end of the reporting period during which the change has occurred.

Information about assumptions used for fair value measurements is included in note 35.

3.	Significant Accounting Policies

The significant accounting policies applied by the Company in the preparation of its separate financial statements in accordance with K-IFRS are included below. The significant accounting policies applied by the Company in these separate financial statements are the same as those applied by the Company in its separate financial statements as of and for the year ended December 31, 2020.

The Company has initially adopted Interest Rate Benchmark Reform Phase 2 – Amendments to K-IFRS No. 1109, Financial Instruments, K-IFRS No. 1039, Financial Instrument: Recognition and Measurement, K-IFRS No. 1107, Financial Instruments: Disclosures and K-IFRS No. 1116, Leases from January 1, 2021.

Interest Rate Benchmark Reform Phase 2 – Amendments provide exceptions as follows:

•	when the basis of determining the contractual cash flows a financial asset or financial liability measured at<br>amortized cost changed as a result of interest rate benchmark reform (“IBOR reform”), the Company updates the effective interest rate of the financial asset or financial liability rather than the carry amount and,
•	when the basis for determining the contractual cash flows of the hedged item or hedging instrument changes as a<br>result of the IBOR reform, the exception permits the hedge relationship to be continued while the Company amends the hedge documentation of that hedging relationship to reflect the changes required by IBOR reform.
---	---

These amended standards are not expected to have a significant impact on the Company’s separate financial statements.

(1) Operating segments

The Company presents disclosures relating to operating segments on its consolidated financial statements in accordance with K-IFRS No. 1108, Operating Segments, and such disclosures are not separately disclosed on these separate financial statements.

(2) Investments in subsidiaries, associates, and joint ventures

(3) Cash and cash equivalents

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

(4) Inventories

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

(5) Non-derivative financial assets

1) Recognition and initial measurement

3.	Significant Accounting Policies, Continued

(5) Non-derivative financial assets, Continued

2) Classification and subsequent measurement

On initial recognition, a financial asset is classified as measured at:

•	FVTPL
•	FVOCI – equity investment
---	---
•	FVOCI – debt investment
---	---
•	Financial assets at amortized cost
---	---

A financial asset is classified based on the business model in which a financial asset is managed and its contractual cash flow characteristics.

Financial assets are not reclassified subsequent to their initial recognition unless the Company changes its business model for managing financial assets, in which case all affected financial assets are reclassified on the first day of the first reporting period following the change in the business model.

A financial asset is measured at amortized cost if it meets both of the following conditions and is not designated as at FVTPL:

•	it is held within a business model whose objective is to hold assets to collect contractual cash flows; and<br>
•	its contractual terms give rise to cash flows that are solely payments of principal and interest on the principal<br>amount outstanding on specified dates.
---	---

A debt investment is measured at FVOCI if it meets both of the following conditions and is not designated as at FVTPL:

•	it is held within a business model whose objective is achieved by both collecting contractual cash flows and<br>selling financial assets; and
•	its contractual terms give rise to cash flows that are solely payments of principal and interest on the principal<br>amount outstanding on specified dates.

On initial recognition of an equity investment that is not held for trading, the Company may irrevocably elect to present subsequent changes in the investment’s fair value in other comprehensive income (“OCI”). This election is made on an investment-by-investment basis.

All financial assets not classified as measured at amortized cost or FVOCI as described above are measured at FVTPL. This includes all derivative financial assets. On initial recognition, the Company may irrevocably designate a financial asset that otherwise meets the requirements to be measured at amortized cost or at FVOCI as at FVTPL if doing so eliminates or significantly reduces an accounting mismatch that would otherwise arise.

2) Classification and subsequent measurement, Continued

The following accounting policies are applied to the subsequent measurement of financial assets.

Financial assets at FVTPL	These assets are subsequently measured at fair value. Net gains and losses, including any interest or dividend income, are recognized in profit or loss.
Financial assets at amortized cost	These assets are subsequently measured at amortized cost using the effective interest method. The amortized cost is reduced by impairment losses. Interest income, foreign exchange gains and losses and impairment are recognized in<br>profit or loss. Any gain or loss on derecognition is recognized in profit or loss.
Debt investments at FVOCI	These assets are subsequently measured at fair value. Interest income calculated using the effective interest method, foreign exchange gains and losses and impairment are recognized in profit or loss. Other net gains and losses<br>are recognized in OCI. On derecognition, gains and losses accumulated in OCI are reclassified to profit or loss.
Equity investments at FVOCI	These assets are subsequently measured at fair value. Dividends are recognized as income in profit or loss unless the dividend clearly represents a recovery of the cost of the investment. Other net gains and losses are recognized<br>in OCI and are never reclassified to profit or loss.

3) Impairment

The Company estimates the expected credit losses (“ECL”) for the debt instruments measured at amortized cost and FVOCI based on the Company’s historical experience and informed credit assessment that includes forward-looking information. The impairment approach is decided based on the assessment of whether the credit risk of a financial asset has increased significantly since initial recognition. However, the Company applies a practical expedient and recognizes impairment losses equal to lifetime ECLs for accounts receivable – trade and lease receivables from the initial recognition.

At each reporting date, the Company assesses whether financial assets measured at amortized cost and debt investments at FVOCI are credit-impaired. A financial asset is ‘credit-impaired’ when one or more events that have a detrimental impact on the estimated future cash flows of the financial asset have occurred.

4) Derecognition

Financial assets

The Company derecognizes a financial asset when:

•	the contractual rights to the cash flows from the financial asset expire; or
•	it transfers the rights to receive the contractual cash flows in a transaction in which either:<br>
---	---
•	substantially all of the risks and rewards of ownership of the financial asset are transferred; or<br>
---	---
•	the Company neither transfers nor retains substantially all of the risks and rewards of ownership and it does not<br>retain control of the financial asset.
---	---

The Company enters into transactions whereby it transfers assets recognized in its statement of financial position, but retains either all or substantially all of the risks and rewards of the transferred assets. In these cases, the transferred assets are not derecognized.

Interest rate benchmark reform

When the basis for determining the contractual cash flows of a financial asset or financial liability measured at amortized cost changed as a result of interest rate benchmark reform, the Company updated the effective interest rate of the financial asset or financial liability to reflect the change that is required by the reform. A change in the basis for determining the contractual cash flows is required by interest rate benchmark reform if the following conditions are met:

•	the change is necessary as a direct consequence of the reform; and
•	the new basis for determining the contractual cash flows is economically equivalent to the previous basis –<br>i.e. the basis immediately before the change.
---	---

When changes were made to a financial asset or financial liability in addition to changes to the basis for determining the contractual cash flows required by interest rate benchmark reform, the Company first updated the effective interest rate of the financial asset or financial liability to reflect the change that is required by interest rate benchmark reform. After that, the Company applied the policies on accounting for modifications to the additional changes.

5) Offsetting

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

(6) Derivative financial instruments, including hedge accounting

1) Hedge accounting

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

On initial designation of the hedge, the Company formally documents the relationship between the hedging instrument(s) and hedged item(s), including the risk management objectives and strategy in undertaking the hedge transaction, together with the methods that will be used to assess the effectiveness of the hedging relationship.

Hedges directly affected by interest rate benchmark reform

When uncertainty arises about the interest rate benchmark designated as a hedged risk and the timing or the amount of the interest rate benchmark-based cash flows of the hedged item or of the hedging instrument as a result of IBOR reform, for the purpose of evaluating whether there is an economic relationship between the hedged items and the hedging instruments, the Company assumes that the interest rate benchmark on which the hedged items and the hedging instruments are based is not altered as a result of interest rate benchmark reform.

For a cash flow hedge of a forecast transaction, the Company assumes that the benchmark interest rate will not be altered as a result of interest rate benchmark reform for the purpose of assessing whether the forecast transaction is highly probable and determining whether a previously designated forecast transaction in a discontinued cash flow hedge is still expected to occur.

The Company will cease applying the specific policy for assessing the economic relationship between the hedged item and the hedging instrument

•	to a hedged item or hedging instrument when the uncertainty arising from interest rate benchmark reform is no<br>longer present with respect to the timing and the amount of the interest rate benchmark-based cash flows of the respective item or instrument; or
•	when the hedging relationship is discontinued.
---	---

When the basis for determining the contractual cash flows of the hedged item or hedging instrument changes as a result of IBOR reform and therefore there is no longer uncertainty arising about the cash flows of the hedged item or the hedging instrument, the Company amends the hedge documentation of that hedging relationship to reflect the change(s) required by IBOR reform.

The Company amends the formal hedge documentation by the end of the reporting period during which a change required by IBOR reform is made to the hedged risk, hedged item or hedging instrument. These amendments in the formal hedge documentation do not constitute the discontinuation of the hedging relationship or the designation of a new hedging relationship.

Hedges directly affected by interest rate benchmark reform, Continued

If changes are made in addition to those changes required by interest rate benchmark reform to the financial asset or financial liability designated in a hedging relationship or to the designation of the hedging relationship, the Company determines whether those additional changes result in the discontinuation of hedging accounting. If the additional changes do not result in the discontinuation of hedging accounting, the Company amend the formal designation of the hedging relationship.

When the interest rate benchmark on which the hedged future cash flows had been based is changed as required by IBOR reform, for the purpose of determining whether the hedged future cash flows are expected to occur, the Company deems that the hedging reserve recognized in OCI for that hedging relationship is based on the alternative benchmark rate on which the hedged future cash flows will be based.

(7) Property and equipment

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

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

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

(7) Property and equipment, Continued

The estimated useful lives of the Company’s property and equipment are as follows:

	Useful lives (years)
Buildings and structures	15, 30
Machinery	3 ~ 8, 10, 30
Other property and equipment	4 ~10

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

(8) Borrowing costs

The Company capitalizes borrowing costs directly attributable to the acquisition, construction or production of a qualifying asset as part of the cost of that asset. Other borrowing costs are recognized in expense as incurred. A qualifying asset is an asset that requires a substantial period of time to get ready for its intended use or sale. Financial assets are not qualifying assets, and assets that are ready for their intended use or sale when acquired are not qualifying assets either.

To the extent that the Company borrows funds specifically for the purpose of obtaining a qualifying asset, the Company determines the amount of borrowing costs eligible for capitalization as the actual borrowing costs incurred on that borrowing during the period less any investment income on the temporary investment of those borrowings. To the extent that the Company borrows funds generally and uses them for the purpose of obtaining a qualifying asset, the Company determines the amount of borrowing costs eligible for capitalization by applying a capitalization rate to the expenditures on that asset. The capitalization rate is the weighted average of the borrowing costs applicable to the borrowings of the Company that are outstanding during the period other than borrowings made specifically for the purpose of obtaining a qualifying asset. The amount of borrowing costs that the Company capitalizes during a period do not exceed the amount of borrowing costs incurred during the period.

(9) Intangible assets

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

Intangible assets, except for goodwill, are amortized on a straight-line basis over the estimated useful lives of intangible assets from the date that they are available for use. The residual value of intangible assets is zero. However, club memberships are expected to be available for use as there are no foreseeable limits to the periods. These intangible assets are determined as having indefinite useful lives and, therefore, not amortized.

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

	Useful lives (years)
Frequency usage rights	2.9 ~ 10
Land usage rights	5
Industrial rights	5, 10
Facility usage rights	10, 20
Other	3 ~ 20

Expenditures on research activities are recognized in profit or loss as incurred. Development expenditures are capitalized only if development costs can be reliably measured, the product or process is technically and commercially feasible, future economic benefits are probable, and the Company intends to and has sufficient resources to complete development and to use or sell the asset. Other development expenditures are recognized in profit or loss as incurred.

(10) Government grants

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

1) Grants related to assets

Government grants whose primary condition is that the Company purchases, constructs or otherwise acquires a long-term asset are deducted in calculating the carrying amount of the asset. The grant is recognized in profit or loss over the life of a depreciable asset as a reduction to depreciation expense.

2) Grants related to income

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

(11) Investment property

Subsequent expenditures are recognized in carrying amount of an asset or as a separate asset if it is probable that future economic benefits associated with the assets will flow into the Company and the cost of an asset can be measured reliably. The carrying amount of those parts that are replaced is derecognized. The costs associated with routine maintenance and repairs are recognized in profit or loss as incurred.

(12) Impairment of non-financial assets

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

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

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

(13) Leases

A contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration.

1) As a lessee

At commencement or on modification of a contract that contains a lease component, the Company allocates the consideration in the contract to each lease component on the basis of its relative stand-alone prices. However, the Company has elected not to separate non-lease components and account for the lease and non-lease components as a single lease component.

The Company recognizes a right-of-use asset and a lease liability at the lease commencement date. The right-of-use asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for any lease payments made at or before the commencement date, plus any initial direct costs incurred and an estimate of costs to dismantle and remove the underlying asset or to restore the underlying asset or the site on which it is located, less any lease incentives received.

The right-of-use asset is subsequently depreciated using the straight-line basis from the commencement date to the end of the lease term, unless the lease transfers ownership of the underlying asset to the Company by the end of the lease term or the cost of the right-of-use asset reflects that the Company will exercise a purchase option. In that case the right-of-use asset will be depreciated over the useful life of the underlying asset, which is determined on the same basis as those of property and equipment. In addition, the right-of-use asset is periodically reduced by impairment losses, if any, and adjusted for certain remeasurements of the lease liability.

The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the Company’s incremental borrowing rate. Generally, the Company uses its incremental borrowing rate as the discount rate.

The Company determines its incremental borrowing rate by obtaining interest rates from various external financing sources and makes certain adjustments to reflect the terms of the lease and type of the asset leased.

Lease payments included in the measurement of the lease liability comprise the following:

•	fixed payments, including in-substance fixed payments;
•	variable lease payments that depend on an index or a rate, initially measured using the index or rate as at the<br>commencement date;
---	---
•	amounts expected to be payable under a residual value guarantee; and
---	---
•	the exercise price under a purchase option that the Company is reasonably certain to exercise, lease payments in<br>an optional renewal period if the Company is reasonably certain to exercise an extension option, and penalties for early termination of a lease unless the Company is reasonably certain not to terminate early.

(13) Leases, Continued

1) As a lessee, Continued

The lease liability is measured at amortized cost using the effective interest method. It is remeasured when there is a change in future lease payments arising from a change in an index or rate, if there is a change in the Company’s estimate of the amount expected to be payable under a residual value guarantee, if the Company changes its assessment of whether it will exercise a purchase, extension or termination option or if there is a revised in-substance fixed lease payment.

The Company presents right-of-use assets that do not meet the definition of investment property in ‘property and equipment’ in the statement of financial position.

The Company has elected not to recognize right-of-use assets and lease liabilities for leases of low value assets and short-term leases. The Company recognizes the lease payments associated with these leases as an expense on a straight-line basis over the lease term.

2) As a lessor

At inception or on modification of a contract that contains a lease component, the Company allocates the consideration in the contract to each lease component on the basis of their relative stand-alone prices.

When the Company acts as a lessor, it determines at lease inception whether each lease is a finance lease or an operating lease.

To classify each lease, the Company makes an overall assessment of whether the lease transfers substantially all of the risks and rewards incidental to ownership of the underlying asset. If this is the case, then the lease is a finance lease; if not, then it is an operating lease. As part of this assessment, the Company considers certain indicators such as whether the lease is for the major part of the economic life of the asset.

When the Company is an intermediate lessor, it accounts for its interests in the head lease and the sub-lease separately. It assesses the lease classification of a sub-lease with reference to the right-of-use asset arising from the head lease, not with reference to the underlying asset. If a head lease is a short-term lease to which the Company applies the exemption described above, then it classifies the sub-lease as an operating lease.

If an arrangement contains lease and non-lease components, then the Company applies K-IFRS No. 1115 to allocate the consideration in the contract.

The Company applies derecognition and impairment requirements in K-IFRS No. 1109 to the net investment in the lease. The Company further regularly reviews estimated unguaranteed residual values used in calculating the gross investment in the lease.

The Company recognizes lease payments received under operating leases as income on a straight-line basis over the lease term as part of ‘other revenue’.

(14) Non-current assets held for sale

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

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

(15) Non-derivative financial liabilities

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

1) Financial liabilities at fair value through profit or loss

2) Other financial liabilities

3) Derecognition of financial liability

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

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

(16) Employee benefits

1) Short-term employee benefits

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

2) Other long-term employee benefits

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

3) Retirement benefits: defined contribution plans

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

4) Retirement benefits: defined benefit plans

At the end of reporting period, defined benefit liabilities relating to defined benefit plans are recognized at present value of defined benefit obligations net of fair value of plan assets.

The calculation is performed annually by an independent actuary using the projected unit credit method. When the fair value of plan assets exceeds the present value of the defined benefit obligation, the Company recognizes an asset, to the extent of the present value of any economic benefits available in the form of refunds from the plan or reduction in the future contributions to the plan.

Remeasurements of the net defined benefit liability (asset), which comprise actuarial gains and losses, the return on plan assets (excluding interest) and the effect of the asset ceiling (if any, excluding interest), are recognized immediately in other comprehensive income. The Company determines net interests on net defined benefit liability (asset) by multiplying discount rate determined at the beginning of the annual reporting period and considers changes in net defined benefit liability (asset) from contributions and benefit payments. Net interest costs and other costs relating to the defined benefit plan are recognized through profit or loss.

When the plan amendment or curtailment occurs, gains or losses on amendment or curtailment in benefits for the past service provided are recognized through profit or loss. The Company recognizes a gain or loss on a settlement when the settlement of defined benefit plan occurs.

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

(17) Provisions

Provisions are recognized when the Company has a present legal or constructive obligation as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation, and a reliable estimate can be made of the amount of the obligation.

A provision is used only for expenditures for which the provision was originally recognized.

Transactions in foreign currencies are translated to the functional currency of the Company at exchange rates at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are retranslated to the functional currency using the exchange rate at the reporting date. Non-monetary assets and liabilities denominated in foreign currencies that are measured at fair value are retranslated to the functional currency at the exchange rate at the date that the fair value was determined.

(20) Share capital

When the Company repurchases its own shares, the amount of the consideration paid is recognized as a deduction from equity and classified as treasury shares. The gains or losses from the purchase, disposal, reissue, or retirement of treasury shares are directly recognized in equity being as transaction with owners.

(21) Hybrid bond

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

(22) Share-based payment

For equity-settled share-based payment transaction, if the fair value of the goods or services received cannot be reliably estimated, the Company measures the value indirectly by reference to the fair value of the equity instruments granted. The related expense with a corresponding increase in capital surplus and others is recognized over the vesting period of the awards.

(23) Revenue

1) Identification of performance obligations in contracts with customers

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

2) Allocation of the transaction price to each performance obligation

The Company allocates the transaction price of a contract to each performance obligation identified on a relative stand-alone selling price basis. The Company uses “adjusted market assessment approach” for estimating the stand-alone selling price of a good or service.

3) Incremental costs of obtaining a contract

The Company pays commissions to its retail stores and authorized dealers in connection with acquiring service contracts. The commissions paid to these parties constituted a significant portion of the Company’s operating expenses. These commissions would not have been paid if there have been no binding contracts with subscribers and, therefore, the Company capitalizes certain costs associated with commissions paid to obtain new customer contracts and amortize them over the expected contract periods

4) Customer loyalty programs

The Company provides customer loyalty points to customers based on the usage of the service to which the Company allocates a portion of consideration received as a performance obligation distinct from wireless telecommunications services. The amount to be allocated to the loyalty program is measured according to the relative stand-alone selling price of the customer loyalty points. The amount allocated to the loyalty program is deferred as a contract liability and is recognized as revenue when loyalty points are redeemed.

5) Consideration payable to a customer

Based on the subscription contract, a customer who uses the Company’s wireless telecommunications services may receive a discount for purchasing goods or services from a designated third party. The Company pays a portion of the price discounts that the customer receives to the third party which is viewed as consideration payable to a customer. The Company accounts for the amounts payable to the third party as a reduction of the wireless telecommunications service revenue.

(25) Income taxes

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

1) Current tax

In accordance with the tax-consolidation system, the Company calculates current taxes on the consolidated taxable income for the Company and its subsidiaries that meet the criteria for the consolidated income tax returns and recognizes the income tax payable as current tax liabilities of the Company.

2) Deferred tax

Deferred tax is recognized by using the asset-liability method in respect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. The Company recognizes a deferred tax liability for all taxable temporary differences, except for the difference associated with investments in subsidiaries and associates that the Company is able to control the timing of the reversal of the temporary difference and it is probable that the temporary difference will not reverse in the foreseeable future. The Company recognizes a deferred tax asset for all deductible temporary differences, to the extent that it is probable that the temporary difference will reverse in the foreseeable future and taxable profit will be available against which the temporary difference can be utilized.

A deferred tax asset is recognized for the carryforward of unused tax losses and unused tax credits to the extent that it is probable that future taxable profit will be available against which the unused tax losses and unused tax credits can be utilized. Future taxable profit is dependent on the reversal of taxable temporary differences. If there are insufficient taxable temporary differences to recognize the deferred tax asset, the business plan of the Company and the reversal of existing temporary differences are considered in determining the future taxable profit.

The Company reviews the carrying amount of a deferred tax asset at the end of each reporting period and reduces the carrying amount to the extent that it is no longer probable that sufficient taxable profit will be available to allow the benefit of part or all of that deferred tax asset to be utilized.

2) Deferred tax, Continued

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the period when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period. The measurement of deferred tax liabilities and deferred tax assets reflects the tax consequences that would follow from the manner in which the Company expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities.

Deferred tax assets and liabilities are offset only if the Company has a legally enforceable right to offset the amount recognized and intends to settle the current tax liabilities and assets on a net basis. Income tax expense in relation to dividend payments is recognized when liabilities relating to the dividend payments are recognized.

3) Uncertainty over income tax treatments

The Company assesses the uncertainty over income tax treatments pursuant to K-IFRS No. 1012. If the Company concludes it is not probable that the taxation authority will accept an uncertain tax treatment, the Company reflects the effect of uncertainty for each uncertain tax treatment by using either of the following methods, depending on which method the entity expects to better predict the resolution of the uncertainty:

•	The most likely amount - the single most likely amount in a range of possible outcomes.
•	The expected value - the sum of the probability-weighted amounts in a range of possible outcomes.<br>
---	---

(26) Earnings per share

The Company presents basic and diluted earnings per share (EPS) data for its ordinary shares. Basic EPS is calculated by dividing the profit or loss attributable to ordinary shareholders of the Company by the weighted average number of ordinary shares outstanding during the period, adjusted for own shares held. Diluted EPS is determined by adjusting the profit or loss attributable to ordinary shareholders and the weighted average number of ordinary shares outstanding, adjusted for own shares held, for the effects of all dilutive potential ordinary shares, which comprise share options granted to employees, if any.

Details of loss allowance on accounts receivable – trade as of December 31, 2021 are as follows:

As the Company is a wireless telecommunications service provider, the Company’s financial assets measured at amortized cost primarily consist of receivables from numerous individual customers, and, therefore, no significant credit concentration risk arises.

Receivables related to other revenue mainly consist of receivables from corporate customers. The Company transacts only with corporate customers with credit ratings that are considered to be low at credit risk. In addition, the Company is not exposed to significant credit concentration risk as the Company regularly assesses their credit risk by monitoring their credit rating. While the contract assets are under the impairment requirements, no significant credit risk has been identified.

Goodwill related to merger of Shinsegi Telecom, Inc.	~~W~~	1,306,236		1,306,236

The recoverable amount of the CGU is based on its value in use calculated by applying the post-tax annual discount rate of 6.6% (2020: 6.3%) (pre-tax annual discount rate: 9.0%) to the estimated future post-tax cash flows based on financial budgets for the next five years. An annual growth rate of 0.5% (2020: (-)0.2%) was applied for the cash flows expected to be incurred after five years and is not expected to exceed the Company’s long-term wireless telecommunication industry growth rate. Management of the Company does not expect the total carrying amount of the CGU will exceed the total recoverable amount due to reasonably possible changes from the major assumptions used to estimate the recoverable amount.

35.	Financial Risk Management
(1)	Financial risk management
---	---

The Company is exposed to market risk, credit risk and liquidity risk. Market risk is the risk related to the changes in market prices, such as foreign exchange rates and interest rates. The Company implements a risk management system to monitor and manage these specific risks.

The Company’s financial assets consist of cash and cash equivalents, financial instruments, investment securities, accounts receivable – trade and others, etc. Financial liabilities consist of accounts payable – other, borrowings, debentures, lease liabilities and others.

1)	Market risk
(i)	Currency risk
---	---

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

Monetary assets and liabilities denominated in foreign currencies as of December 31, 2021 are as follows:

(In millions of won, thousands of foreign currencies)
				Liabilities
		Won<br>equivalent		Foreign<br>currencies		Won<br>equivalent
	15,785	~~W~~	18,713		1,203,788	~~W~~	1,427,091

Others	—		172		—		—
		~~W~~	18,965			~~W~~	1,427,996

All values are in US Dollars.

In addition, the Company has entered into cross currency swaps to hedge against currency risk related to foreign currency borrowings and debentures. (See Note 19)

As of December 31, 2021, a hypothetical change in exchange rates by 10% would have increased (decreased) the Company’s income before income tax as follows:

(In millions of won)
			If decreased by 10%
	1,419			(1,419	)

35.	Financial Risk Management, Continued
(1)	Financial risk management, Continued
---	---
1)	Market risk, Continued
---	---
(ii)	Interest rate risk
---	---

The interest rate risk of the Company arises from borrowings, debentures and long-term payables –other. Since the Company’s interest-bearing assets are mostly fixed-interest bearing assets, the Company’s revenue and operating cash flows from the interest-bearing assets are not influenced by the changes in market interest rates.

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

As of December 31, 2021, floating-rate debentures amount to ~~W~~355,650 million, and the Company has entered into interest rate swaps to hedge interest rate risk related to the floating-rate debentures as described in note 19. Therefore, income before income taxes for the year ended December 31, 2021 would not have been affected by the changes in interest rates of floating-rate debentures.

Interest rate benchmark reform and associated risks

The Company plans to include fallback clauses into financial instruments relating to LIBOR to which calculation has not been suspended yet, or change their LIBOR directly to alternative interest rates before the calculation is suspended.

Interest rate benchmark reform and associated risks, Continued

The Company’s financial instruments exposed to the risk arising from interest rate benchmark reform as of December 31, 2021 are indexed to the USD LIBOR. The Company is exposed to legal risk to amend the terms of contracts on the financial instruments subject to interest rate benchmark reform as well as process and operation risks to manage such amendments. In addition, the Company is exposed to the risk of monitoring the market trend regarding the alternative interest rate and establishing the corresponding risk management strategy. If the IBOR is designated as the hedged item, the Company is required to replace it to an alternative benchmark interest and review the effects on the hedging relationship. In addition, the Company is exposed to the risk of minimizing hedge ineffectiveness by aligning the method and timing of the transition to the alternative benchmark interest applied to the hedged item and the hedging instrument.

The Company evaluates the extent to which contracts reference IBOR cash flows, whether such contracts will need to be amended as a result of IBOR reform and how to manage communication about IBOR reform with counterparties.

Non-derivative financial liabilities

The Company’s non-derivative financial liabilities subject to Interest rate benchmark reform as of December 31, 2020 were floating-rate bonds indexed to USD LIBOR. As explained above, the Company is discussing with the counterparty about including the fallback clauses as of December 31, 2021.

Derivatives

The Company’s derivative instruments designated as cash flow hedge are governed by contracts based on the International Swaps and Derivatives Association (ISDA)’s master agreements. As part of interest rate benchmark reform, ISDA has included a new fallback clause regarding which alterative benchmark interest rate to be applied when the calculation of major IBOR is suspended in the master agreement. The master agreement is applied to derivative contracts after January 25, 2021 and the transaction parties is required to adhere to ISDA protocol to include the same fallback clause to derivative contracts before January 25, 2021. The Company has adhered to ISDA protocol for transition to the alternative benchmark interest rate and the fallback clause will be included when counterparties adhere to the protocol to include. The Company’s counterparties have adhered to ISDA protocol and agreed to include the fallback clause.

Hedge accounting

The Company’s hedged items and hedging instruments as of December 31, 2021 are indexed to USD LIBOR. These benchmark rates are quoted each day and the IBOR cash flows are exchanged with counterparties as usual.

Credit risk is the risk of financial loss to the Company if a customer or counterparty to a financial instrument fails to meet its contractual obligations. To manage credit risk, the Company evaluates the credit worthiness of each customer or counterparty considering the party’s financial information, its own trading records and other factors. Based on such information, the Company establishes credit limits for each customer or counterparty.

(i)	Accounts receivable – trade and contract assets
---	---

The Company establishes a loss allowance in respect of accounts receivable – trade and contract assets. The main components of this allowance are a specific loss component that relates to individually significant exposures and a collective loss component established for groups of similar assets in respect of losses that are expected to occur. The collective loss allowance is determined based on historical data of collection statistics for similar financial assets. Details of changes in loss allowance for the year ended December 31, 2021 are included in note 5.

(ii)	Debt investments

The credit risk arises from debt investments included in ~~W~~379,354 million of financial instruments, ~~W~~900 million of investment securities, and ~~W~~1,029,221 million of loans and other receivables. To limit the exposure to this risk, the Company transacts only with financial institutions with credit ratings that are considered to be low credit risk.

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

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

The Company’s maximum exposure to credit risk is equal to each financial asset’s carrying amount. The gross carrying amounts of each financial asset except for the accounts receivable – trade and derivative financial assets as of December 31, 2021 are as follows:

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

---	---

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

Fair value of the financial instruments that are traded in an active market (financial assets at FVOCI) is measured based on the bid price at the end of the reporting date.

The Company uses various valuation methods for determination of fair value of financial instruments that are not traded in an active market. Derivative financial contracts and long-term liabilities are measured using the discounted present value methods. Other financial assets are determined using the methods such as discounted cash flow and market approach. Inputs used to such valuation methods include swap rate, interest rate and risk premium, and the Company performs valuation using the inputs which are consistent with natures of assets and liabilities measured.

Interest rates used by the Company for the fair value measurement as of December 31, 2021 are as follows:

	Interest rate
Derivative instruments		0.32% ~ 1.90%
Borrowings and debentures		1.64% ~ 2.33%
Long-term payables – other		1.62% ~ 2.39%

Independent Auditors’ Report on Internal Control over FinancialReporting

Based on a report originally issued in Korean

To the Board of Directors and Shareholders of

SK Telecom Co., Ltd.:

Opinion on Internal Control over Financial Reporting

We have audited SK Telecom Co., Ltd.’s (the “Company”) Internal Control over Financial Reporting (“ICFR”) as of December 31, 2021, based on the criteria established in Conceptual Framework for Designing and Operating ICFR (“ICFR Design and Operation Framework”) issued by the Operating Committee of Internal Control over Financial Reporting in the Republic of Korea (the “ICFR Committee”).

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on ICFR Design and Operation Framework.

We also have audited, in accordance with Korean Standards on Auditing (“KSAs”), the separate financial statements of the Company, which comprise the separate statement of financial position as of December 31, 2021 and 2020, the separate statements of income, comprehensive income, changes in equity, and cash flows for the year then ended, and notes, comprising significant accounting policies and other explanatory information, and our report dated March 10, 2022 expressed an unmodified opinion on those separate financial statements.

Basis for Opinion

We conducted our audit in accordance with KSAs. Our responsibilities under those standards are further described in the Auditors’ Responsibilities for the Audit of the Internal Control over Financial Reporting section of our report. We are independent of the Company in accordance with the ethical requirements that are relevant to our audit of the internal control over financial reporting in the Republic of Korea, and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Responsibilities of Management andThose Charged with Governance for the Internal Control over Financial Reporting

The Company’s management is responsible for designing, operating, and maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Report on the Operation of Internal Control over Financial Reporting.

Those charged with governance are responsible for overseeing the Company’s internal control over financial reporting.

Auditors’ Responsibilities for the Audit of the Internal Control over Financial Reporting

Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We conducted our audit in accordance with KSAs. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit of internal control over financial reporting involves performing procedures to obtain audit evidence about whether a material weakness exists. The procedures selected depend on the auditor’s judgment, including the assessment of the risks that a material weakness exists.

Definition and Inherent Limitations of Internal Control over Financial Reporting

The Company’s internal control over financial reporting is a process effected by those charged with governance, management, and other personnel, designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with Korean International Financial Reporting Standards (“K-IFRS”). The Company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with K-IFRS, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent, or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The engagement partner on the audit resulting in this independent auditors’ report is In Hye Kang.
