B. Industry Characteristics

The telecommunications services market can be categorized into telecommunications services (such as fixed-line, wireless and leased line services, as well as sales intermediary services relating thereto and value-added services) and broadcasting and telecommunications convergence services (including IPTV and integrated fixed-line and mobile telecommunications 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 the size of the population that uses telecommunications services and telecommunications expenditures per capita. While it is possible for Korean telecommunications service providers to provide services abroad through acquisitions or otherwise, foreign telecommunications services markets have their own characteristics depending, among others, on the regulatory environment and demand for telecommunications services.

C. Growth Potential

The Korean mobile communications 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. In addition, the ultra-low latency and high capacity characteristics of 5G networks as well as the advancement of AI are expected to accelerate the introduction of new services and the growth of IoT-based B2B businesses.

D. Domestic and Overseas Market Conditions

The Korean mobile communications market includes the entire population of Korea with mobile communications 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 of 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.

Set forth below is the historical market share of the Company (excluding MVNO subscribers).

E. Competitive Strengths

In 2021, the Company successfully completed the Spin-off in order to maximize shareholder value. In the same year, the Company also unveiled its “SKT 2.0” vision to pursue the maximization of its overall enterprise value centered around five major business areas. In November 2022, the Company announced its differentiated “AI Company” vision to further organize and clarify the direction of SKT 2.0 and combine AI with connectivity technologies based on its main telecommunications business. In September 2023, as part of the Company’s effort to transform into a “global AI company,” the Company announced its new “AI Pyramid” strategy, which aims to bring innovation across various industrial and lifestyle areas centered around three key aspects. The AI Pyramid strategy is in the form of a pyramid and integrates a “self-reinforcement model,” which seeks to strengthen the Company’s relationship with its customers through advances in the Company’s AI technology and the creation of AI services, with a “cooperation model,” which focuses on AI-related alliances. Through these initiatives, the Company is striving to transform into a global AI company.

For the year ended December 31, 2023, the Company recorded Won 17.6 trillion in operating revenue and Won 1.75 trillion in operating profit on a consolidated basis. The increased competitiveness of telecommunications services and the rapid progress in new growth businesses such as B2B have enabled the Company to continue to improve its operating results.

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.

14

PS&Marketing, a subsidiary of the Company, provides a sales platform for products of the Company and SK Broadband including fixed-line and wireless telecommunications 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. Overview

For the year ended December 31, 2023, SK Broadband recorded Won 4.27 trillion in revenue on a consolidated basis, which represented a 2.9% increase from Won 4.16 trillion for the year ended December 31, 2022. Such increase was primarily attributable to the growth of SK Broadband’s media business resulting from an increase in the number of subscribers and the growth of its B2B business primarily focused on new data centers.

SK Broadband’s business is divided into the media business segment, which provides IPTV and cable TV services, and the fixed-line business segment, which provides high-speed Internet, telecommunications, leased lines and data center services.

For the year ended December 31, 2023, the media business segment recorded Won 1.91 trillion in revenue, which represented a 1.2% increase compared to the year ended December 31, 2022. For the year ended December 31, 2023, the fixed-line business segment recorded Won 2.37 trillion in revenue, which represented a 4.2% increase compared to the year ended December 31, 2022.

B. Industry Characteristics

The domestic telecommunications 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 telecommunications service expenditures in light of the domestic income level. Domestic telecommunications companies may expand overseas through acquisitions or direct expansion, but the overseas telecommunications 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 telecommunications 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.

15

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 communications services is developed.

In the high-speed Internet services market, the demand for Giga Internet services has been continuing to increase due to the popularization of mobile and home IoT devices and the expansion of large media services including video streaming services.

In the paid broadcasting market, competition for content has been intensifying, at the center of which are large over-the-top operators with strength in exclusive content. Reflecting a rapid change in content consumption patterns and behaviors of viewers, the Company is preparing for 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 expects to see growth in new business areas, following the emergence of new services powered by new technologies including AI and metaverse. The Company is continuing its efforts to generate stable returns by strengthening its competitiveness in the traditional fixed line-based business through expansion of core infrastructure including data centers and leased lines, for which market demand has been continually growing.

** High-speed Internet and fixed-line telephone subscribers represent the number of subscribers as of December 31, 2023, while IPTV and cable TV subscribers represent the average number of subscribers in the first half of 2023.

D. 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. Overall, the telecommunications services market is not expected to be particularly affected by economic downturns due to the low income elasticity of demand for telecommunications services.

16

The Company is engaged in a number of business areas including high-speed Internet, home telephone, corporate business, IPTV and cable TV pursuant to the relevant communications regulations such as the Telecommunications Business Act, the Internet Multimedia Broadcast Services Act and the Broadcasting Act. In each of its principal business areas, the Company competes on the basis of price, service quality and speed. In the IPTV business, the ability to offer complex services and differentiated contents are becoming increasingly important. General telecommunications businesses operate in a licensed industry with a high barrier of entry, which is dominated by the Company, KT and LG U+.

[Other Businesses]

A. Other businesses

The commercial retail data broadcasting channel business offers an interactive service that integrates television home shopping and data home shopping services. Such integrated service allows television viewers to organize various product categories on the television screen and select and purchase desired products using a television remote control or mobile device, unlike traditional home shopping services that only allowed for real-time purchase through the relevant 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 provides personalized digital television shopping services through “Stoa ON,” the industry’s first cloud-based television application service. 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.

Sapeon, an AI semiconductor company, launched “X330,” its next-generation inference AI chip. Sapeon has been in discussions with global server manufacturers regarding potential cooperation to expand the sales of X330, and it plans to cooperate with businesses relating to next-generation AI data centers.

[Fixed-line Business]

On May 15, 2023, SK Broadband newly launched the Internet Protocol Cable TV (“IP CATV”) product. Existing cable TV services were allowed to transmit broadcasting contents only through the radio frequency (“RF”) method. However, pursuant to recent amendments to the Broadcasting Act which recognize technology neutrality, cable TV services are now allowed to transmit broadcasting contents through non-RF methods, thereby allowing the Company to introduce the new IP CATV product.

Compared to the RF method, the Internet protocol method provides diverse and high-quality services on a more stable basis. The Company expects these factors will lead to greater customer satisfaction and competitiveness of its cable TV services products through improvement in broadcasting quality.

In order to cater to the diverse needs of the customers, the IP CATV product is offered through three plans. The “B tv pop 100” plan offers basic channels (109 channels), the “B tv pop 180” plan offers channels with high viewer ratings (184 channels) and the “B tv pop 230” plan offers all cable TV channels (231 channels). Based on a three-year contract, the plans cost Won 7,700, Won 11,000, and Won 13,200, respectively. As for the B tv pop 180 and B tv pop 230 plans, customers can receive an additional discount of Won 3,300 if they combine the plans with the broadband Internet service.

In addition, in October 2023, SK Broadband launched the “Cable Family Combination” plan which offers a discount when bundling cable Internet and wireless subscription plans. This plan is similar to its “Modern Family Combination” plan which bundles Internet and IPTV services, and provides enhanced benefits compared to the existing “Whole Family Cable” plan which bundles fixed-line and wireless services. Depending on the chosen cable Internet subscription product (cable optical local area network, cable Giga light and cable Giga), subscribers are eligible for a discount ranging between 20% and 30% of the three-year contract fee for cable Internet services. Subscribers are also eligible for a discount ranging between Won 3,500 for one wireless telephone line and Won 24,000 for five lines.

SK Broadband also provides a variety of other subscription plans based on consumer demand, which may be reviewed on SK Broadband’s website at www.skbroadband.com.

The number of registered patents and trademarks is subject to continual change due to the acquisition of new rights, expiration of terms, abandonments and dispositions.

C. Business-related Pollutants and Environmental Protection

[SK Telecom]

The Company does not directly engage in any manufacturing and therefore does not undertake any industrial processes that emit pollutants into the air or industrial processes in which hazardous materials are used. Nevertheless, the Company clearly recognizes the severity of the climate crisis and has been diligently fulfilling its social obligations by establishing a systematic and practical environmental management strategy system. Under the vision of “realizing a sustainable future based on ICT” and to achieve Net Zero by 2050, the Company is making efforts to (1) preemptively respond to climate change, (2) improve its environmental management system and (3) create an eco-friendly green culture. To this end, the Company was one of the first information technology companies in Korea to join the RE100 (Renewable Electricity 100%) initiative and signed a green premium contract with Korea Electric Power Corporation. The Company has been implementing company-wide adoption of renewable energy through efforts such as installing solar power generation equipment in its office buildings and base stations. In addition, the Company leads in energy savings and environmental protections based on ICT technology, and recently became the first company in the telecommunications industry to obtain carbon emission rights by reducing greenhouse gas through integration of telecommunications equipment and technology upgrades.

[SK Broadband]

SK Broadband does not directly engage in any manufacturing processes that emit environmental pollutants, and more than 99% of its greenhouse gas emissions is indirect emissions from its use of external electricity. SK Broadband was selected as a business subject to allocation of emission permits as part of Korea’s greenhouse gas emissions trading scheme that commenced in 2015, and it actively fulfills its obligations and consistently achieves the targets set by the government.

In 2021, SK Broadband declared its goal to achieve Net Zero by 2045 in an effort to actively participate in the international community’s response to climate change. Prior to the declaration, SK Broadband had already subscribed to the RE100 initiative in 2020. Since 2021, SK Broadband has participated in Korea Electrical Power Corporation’s renewable energy power purchase program, “Green Premium,” to purchase renewable energy and has installed additional solar power generation facilities to increase the self-production and use of renewable energy.

2. Dividends and Others

A. Dividend Policy

The Company seeks to enhance its enterprise value through distribution of cash dividends based on stable business performance and by increasing long-term shareholder returns based on sustainable growth. To this end, the Company has been prioritizing its capital management principle of balancing investment for growth and shareholder returns.

The Company determines the amount of 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.

24

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 in March 2021 and has been distributing quarterly dividends since the second quarter of 2021.

In August 2021, the Company disclosed its medium- to long-term dividend policy aimed at enhancing the predictability of shareholder returns, according to which the total amount of dividends is determined within 30% to 40% of its “EBITDA – capital expenditures” on a separate basis. Since then, the Board of Directors have made determinations on dividends in accordance with such policy.

Furthermore, the Company has engaged in repurchases and cancelations of its own shares from time to time to enhance its enterprise value in consideration of the market price of the Company’s shares and its financial resources. From 2020 to 2021, the Company purchased approximately Won 500 billion of treasury shares, and in May 2021, the Company canceled 8,685,568 units of previously acquired treasury shares (10.76% of the total number of shares issued at the time) to enhance shareholder value. In addition, in 2023, the Company purchased approximately Won 300 billion of treasury shares, and in February 2024, the Company canceled 4,043,091 units of treasury share (1.85% of the total number of shares issued at the time).

4. Other Matters Related to Financial Information

A. Restatement of the Financial Statements

Pursuant to the resolutions of the Board of Directors and the General Meeting of Shareholders on June 10, 2021 and October 12, 2021, respectively, the Company conducted the Spin-off effective as of November 1, 2021. As a result of the Spin-off, the Company discontinued certain parts of the security, commerce and other businesses operated by its major subsidiaries, 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, were excluded from the scope of the Company’s consolidation. The Company classified and separately showed profit (loss) from such discontinued businesses in its consolidated statement of profit and loss for the year ended December 31, 2021 in the Company’s audit report and annual business report as of and for the year ended December 31, 2021 pursuant to the application of K-IFRS 1105. The consolidated statement of profit and loss for the year ended December 31, 2020 was restated accordingly for comparative purposes. Furthermore, the Spin-off caused a change in the Company’s business segments, which led to a restatement of prior years’ segment information, and the business of SK Stoa, which had previously been classified as part of the Company’s commerce segment, was reclassified as part of the Company’s other business segment.

(3) Policies for Loss Allowance

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

A. Summary of Business Performance

In 2023, difficult business conditions persisted in light of high interest and inflation rates and a slowdown in economic growth. Despite such adverse conditions, the Company’s revenue increased by 1.8% from 2022 to Won 17.61 trillion in 2023, and operating profit increased by 8.8% from 2022 to Won 1.75 trillion in 2023, mainly due to a continual increase in the number of the Company’s 5G wireless subscribers and visible realization of growth businesses such as B2B.

The Company’s 5G wireless services, which recorded over 15.67 million subscribers as of December 31, 2023, accounted for 68% of the Company’s total number of subscribers. The Company also maintained the growth of its paid television subscribers at 9.55 million subscribers and high-speed Internet subscribers at 6.93 million subscribers, in each case as of December 31, 2023.

The Company’s assets as of December 31, 2023 decreased by 3.8% from the end of the previous year mainly due to a decrease in current assets including cash and cash equivalents, as well as a decrease in non-current assets including property and equpment and intangible assets. Liabilities as of December 31, 2023 decreased by 6.6% from the end of the previous year mainly due to a decrease in current liabilities including short-term borrowings and accounts payable — trade.

Although an overall slowdown in economic growth is expected to continue in 2024, the Company plans to navigate through such headwinds by focusing on enhancing profitability through operational efficiency, while nurturing growth businesses, including data centers, based on innovations in AI technology.

C. Analysis of Change in Key Indicators

The Company’s revenue increased in 2023 due mainly to increases in the number of SK Telecom’s 5G subscribers and SK Broadband’s paid-TV subscribers, as well as growth in sales centered around the B2B business, resulting in a 1.8% increase compared to 2022.

The Company’s operating profit increased by 8.8% in 2023 compared to 2022 due mainly to the growth of the Company’s businesses and the Company’s efforts in stabilizing key costs.

3. Analysis of Consolidated Financial Position

A. General Factors Impacting Financial Position

In 2023, the global economy experienced mild growth as the impact of high interest rates continued, and a rapid turnaround of this trend appears unlikely in 2024. Future macroeconomic environment is expected to be affected by various uncertainties including monetary policies of major countries, geopolitical conflicts, international oil prices and fluctuations in the prices of raw material.

Under such circumstances, the Company has set forth its vision to transform into an “AI Company,” and systemized its businesses into three key aspects of AI infrastructure, AI transformation and AI service. The Company has redefined its core business as AI and has been focusing its capabilities in maximizing enterprise value by enhancing its AI technology and service capabilities.

Although it is possible that the Company’s growth rate may slow down as the 5G market approaches maturity, the Company aims to maintain its competitiveness by providing differentiated products and services to users and to develop growth businesses such as B2B into key sources of revenue.

(a) Wireless Communications Business

[1] Market Conditions

Wireless communications service has the characteristics of a domestic industry because its business area is limited to Korea. As a result, the size of the industry is greatly affected by domestic market conditions, including the population using domestic telecommunications services and the level of telecommunications expenditures by income level.

The Korean mobile communications market is considered to have reached its maturation stage with more than a 100% penetration rate.

(b) Fixed-Line Communications Business

[1] Market Conditions

The domestic telecommunications service industry is a domestic industry whose coverage area is limited to Korea, and the size of the industry is significantly affected by domestic economic factors, including the domestic user population and the level of telecommunications service expenditures by income level.

42

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. It is a mature market where the impact of general economic fluctuations is relatively low as the level of competition has stabilized due to a reduced degree of differentiation among players.

The price, quality and speed of services are the primary competitive factors, and in the case of IPTV business, advanced services based on new technology and content differentiation are emerging as competitive factors.

• Fixed-line Telecommunications

SK Broadband’s fixed-line telecommunications business consists of high-speed internet services, corporate business and residential telephone services. In its high-speed internet services, the number of subscribers to premium plans such as Giga Internet has been increasing, reaching 6.93 million as of December 31, 2023.

See Note 36(1) of the notes to the Company’s audited consolidated financial statements attached hereto for further information regarding the company’s exchange rate risk.

G. Asset Impairment and Write-downs

(1) Impairment assessment of goodwill in cash-generating units of fixed-line businesses

As described in Notes 3(10) and 16 of the notes to the Company’s audited consolidated financial statements attached hereto, the Company assesses impairment of goodwill allocated to a cash generating unit (“CGU”) at least annually or when there is an indication of possible impairment by comparing the carrying amount of a CGU to its recoverable amount based on value-in-use (“VIU”). The amount of goodwill allocated to the fixed-line telecommunications services CGU was Won 764,082 million as of December 31, 2023.

In carrying out the goodwill impairment assessment, the Company compares the carrying amount of the fixed-line telecommunications services CGU and its VIU based on discounted cash flow forecasts. The Company’s independent auditor has identified the goodwill impairment assessment for the fixed-line telecommunications services CGU as a key audit matter due to inherent uncertainties and significant judgment involved in management’s estimates of major assumptions such as estimates of future operating revenue, perpetual growth rate and discount rate, all of which have a significant impact on the determination of a VIU. The primary audit procedures performed by the independent auditor for this key audit matter include:

• Assessing the competence and objectivity of the external specialist utilized by management;

• Evaluating the appropriateness of the valuation method and assumptions applied by management by involving the independent auditor’s internal specialist;

• Performing a sensitivity analysis for both the discount rate and the perpetual growth rate applied to discounted cash flow forecasts to assess the impact of changes in these key assumptions on the conclusion reached by management in its impairment assessment;

• Evaluating the reasonableness of management’s future cash flow forecasts by comparison with financial budgets approved by management; and

• Performing a retroactive assessment of the prior periods’ cash flow forecasts by comparison with the actual results.

(2) Impairment assessment 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.

For more information on asset impairment, see the notes to the Company’s audited consolidated financial statements attached hereto.

H. Annual Business Plan for 2024

The Company released the following management plan for 2024 through its earnings announcement on February 5, 2024.

C. Equity Compensation Plans

(1) PSUs

Since 2023, the Company has been granting PSUs to certain registered officers (including the representative director), unregistered officers and officers of subsidiaries in order to align management and shareholder interests and further align growth in the Company’s enterprise value with management compensation. Future performance targets are set when entering into the relevant stock compensation agreement, and the final number of shares to be received by each grantee will be determined based on the achievement levels of such targets, subject to approval by the Board of Directors.

64

PSUs ranging between 0% and 100% of a grantee’s annual salary is initially granted, and such units are converted into shares ranging between 0% and 200% of the grantee’s annual salary at the time of the PSU grant after a three-year vesting period based on the rates of increase in the Company’s share price and the KOSPI 200 Index. In consideration of the representative director’s role and importance, additional shares of up to 100% of the representative director’s annual salary at the time of the PSU grant may be granted in recognition of his or her outstanding achievements if the share price increases by more than 100% and such increase has outpaced the increase in the KOSPI 200 Index by more than 50%. The validity of the PSUs is dependent on the grantee meeting a minimum term of incumbency under his or her title until the end of the year in which the PSUs were granted. The number of shares granted is subject to adjustments in cases of certain events including capital increases, stock splits, reverse stock splits and distribution of stock dividends.

(As of December 31, 2023)
Number of grantees	Number of PSUs granted		Shares granted in the year ended December 31, 2023		Cumulative shares granted as of December 31, 2023		Remaining shares to be granted
194		228,708		—		—		228,708

(2) Stock Appreciation Rights (“SARs”)

In 2021 and 2022, the Company granted SARs to certain executive officers as equity compensation following approval by the Board of Directors.

SARs entitle the grantee to receive in cash the product of (a) the difference between the share price at the time of grant and the share price after a three-year vesting period and (b) the number of shares of the Company’s common stock equal to 100% of a grantee’s annual salary.

If the grantee’s employment with the Company is terminated within two years of the grant date, no such payment is made. If a grantee’s employment with the Company is terminated at a date between two and three years after the grant date, settlement is made based on the share price on the termination date. The maximum payout is capped at 100% of the grantee’s annual salary at the time of grant.

(3) Shareholder Participation Program

Since 2021, pursuant to Article 342 of the Korean Commercial Code, the Company has been operating the “Shareholder Participation Program” as equity compensation in order to align management and shareholder interests and strengthen commitment to enhance enterprise value.

All employees of the Company, including the representative director, are eligible to participate in the Shareholder Participation Program, under which the Company grants treasury shares equal to a portion of a participating employee’s bonus, upon individual application. The grant of treasury shares is subject to resolution by the Board of Directors.

The participating employee must be employed with the Company at the time of actual grant and there is no transfer restriction period. The number of treasury shares granted is subject to adjustments in cases of certain events including capital increases, stock splits, reverse stock splits and distribution of stock dividends.

Independent Auditor’s Report

(English Translation of a Report Originally Issued in Korean)

The Shareholders and Board of Directors

SK Telecom Co., Ltd.

Opinion

We have audited the accompanying consolidated financial statements of SK Telecom Co., Ltd. and its subsidiaries (collectively referred to as the “Group”) which comprise the consolidated statement of financial position as of December 31, 2023 and 2022, and the consolidated statements of income, comprehensive income, changes in equity and cash flows for each of the two years in the period ended December 31, 2023, and notes to the consolidated financial statements, including a summary of material accounting policies.

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, 2023 and 2022, and its consolidated financial performance and its consolidated cash flows for each of the two years in the period ended December 31, 2023 in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (“KIFRS”).

We also have audited the Group’s internal control over financial reporting as of December 31, 2023, based on the criteria established in Conceptual Framework for Designing and Operating Internal Control over Financial Reporting in accordance with the Korean Standards on Auditing (“KSA”) issued by the Operating Committee of internal control over financial reporting, and our report dated March 6, 2024 expressed an unqualified opinion thereon.

Basis for Opinion

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

Key Audit Matters

Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the consolidated financial statements of the current period. 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. For each matter below, our description of how our audit addressed the matter is provided in that context.

1. Cut-off of revenue from wireless services.

As described in notes 3 (21) and 4 (2) to the consolidated financial statements, the Group’s revenue from the wireless services is recognized based on data from a complex array of information technology systems which process a significant volume of transactions with its customers. Furthermore, the transactions involve a variety of contractual terms from new subscriptions to deactivations or churn, and changes of rate plans during the period. Therefore, we have identified timing of revenue recognition related to the Group’s wireless services as a key audit matter. Related revenue from the wireless services amounted toW10,328,980 million in 2023.

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

• Inspecting major contracts with subscribers to assess whether the Group’s revenue recognition policies based on the terms and conditions as set out in the contracts, are consistent with reference to the requirements of KIFRS 1115;

• Testing internal controls relating to the timing of revenue recognition for the wireless services; and

• Evaluating the appropriateness of the timing of revenue recognition by recalculating the prorated revenue based on the subscribed rate plan and comparing it with the billing information.

2. Impairment assessment of goodwill for the fixed-line telecommunication services cash generating unit

As described in notes 3 (10) and 16 to the consolidated financial statements, the Group assesses impairment of goodwill allocated to a cash generating unit (“CGU”), at least, annually or when there is an indication of possible impairment by comparing the carrying amount of the CGU to its recoverable amount based on value-in-use (”VIU”). The amount of goodwill allocated to the fixed-line telecommunication services CGU isW764,082 million as of December 31, 2023.

In carrying out the goodwill impairment assessment, the Group compared the carrying amount of the fixed-line telecommunication services CGU and its value in use (“VIU”) based on discounted cash flow forecasts. We have identified the goodwill impairment assessment for the fixed-line telecommunication services CGU as a key audit matter due to the inherent uncertainties and significant judgement involved in management’s estimates around the major assumptions such as estimates of future operating revenue, perpetual growth rate and discount rate, all of which have a significant impact on the determination of the VIU.

The primary audit procedures we have performed for this key audit matter include:

• Assessing the competence and objectivity of the external specialist utilized by management;

• Evaluating the appropriateness of the valuation method and assumptions applied by management by involving our internal specialist;

• Performing a sensitivity analysis for both the discount rate and the perpetual growth rate applied to the discounted cash flow forecasts to assess the impact of changes in these key assumptions on the conclusion reached by management in its impairment assessment;

• Evaluating the reasonableness of management’s future cash flow forecasts by comparison with financial budgets approved by management; and

• Performing a retroactive assessment of the prior periods’ cash flow forecasts by comparison with the actual results.

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

Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with KIFRS, 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.

Auditor’s 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 auditor’s 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 KSA 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 KSA, we exercise professional judgment and maintain professional skepticism throughout the audit. We also:

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

• Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances.

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

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

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

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

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 auditor’s 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 auditor’s report is Yoo, Jung Ho.

2. Basis of Preparation

These consolidated financial statements were prepared in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (“KIFRS”), as prescribed in the Act on External Audits of Stock Companies of Korea. The accompanying consolidated financial statements have been translated into English from Korean financial statements. In the event of any differences in interpreting the financial statements or the independent auditor’s report thereon, Korean version, which is used for regulatory reporting purposes, shall prevail.

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 2, 2024, which will be submitted for final approval at the shareholder’s meeting to be held on March 26, 2024.

(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”);

• liabilities measured at fair value for cash-settled share-based payment arrangement; and

• liabilities (assets) for defined benefit plans recognized at the total present value of defined benefit obligations less 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 KIFRS 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 8), property and equipment and intangible assets (notes 3 (7), (8), 13 and 17), impairment of goodwill (notes 3 (10) and 16), recognition of provision (notes 3 (15) and 20), measurement of defined benefit liabilities (assets) (notes 3 (14) and 21), transaction of derivative instruments (notes 3 (6) and 22) and recognition of deferred tax assets (liabilities) (notes 3 (23) 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 KIFRS, including the level in the fair value hierarchy in which such valuations should be classified.

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

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

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

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

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

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

3. Material Accounting Policies

The material accounting policies applied by the Group in the preparation of its consolidated financial statements in accordance with KIFRS are included below. Except for certain standards and amendments which are effective for annual periods beginning on or after January 1, 2023, the material accounting policies applied by the Group in these consolidated financial statements are the same as those applied by the Group in its consolidated financial statements as of and for the year ended December 31, 2022. The Group has not early adopted any standards, interpretations or amendments that have been issued but are not yet effective.

The new and amended standards and interpretations that are effective for annual periods beginning on or after January 1, 2023 are as follows. These amended standards had no material impact on the Group’s consolidated financial statements.

• Disclosure of Accounting Polices (Amendments to KIFRS 1001)

• Disclosures of Profit or Loss on Financial Liabilities with Conditions for Adjusting an Exercise Price (Amendments to KIFRS 1001)

• Definition of Accounting Estimates (Amendments to KIFRS 1008)

• Deferred Tax related to Assets and Liabilities Arising from a Single Transaction (Amendments to KIFRS 1012)

• KIFRS 1117 Insurance Contracts and its amendments

• International tax reform - Pillar Two model rules (Amendments to KIFRS 1012)

The Pillar Two model rules is scheduled to take effect for the Group’s fiscal year beginning January 1, 2024. As the Group falls within the scope of the enacted Pillar Two model rules, it has assessed the potential exposure to Pillar Two income tax. The assessment of potential exposure to Pillar Two income tax is based on the most recent tax returns of the Group’s ultimate controlling entity group, country-by-country reporting, and financial statements. The Group expects that the exposure to Pillar Two income tax will be immaterial.

(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 KIFRS 1032 and KIFRS 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.

(2) Basis of consolidation, Continued

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

• its contractual terms give rise to cash flows that are solely payments of principal and interest on the principal amount outstanding on specified dates.

(5) Non-derivative financial assets, Continued

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 selling financial assets; and

• its contractual terms give rise to cash flows that are solely payments of principal and interest on the principal amount outstanding on specified dates.

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

All financial assets not classified as measured at amortized cost or FVOCI as described above are measured at FVTPL. 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 profit or loss. Any gain or loss on derecognition is recognized in profit or loss.
Debt investments at FVOCI	These assets are subsequently measured at fair value. Interest income calculated using the effective interest method, foreign exchange gains and losses and impairment are recognized in profit or loss. Other net gains and losses are recognized in OCI. On derecognition, gains and losses accumulated in OCI are reclassified to profit or loss.
Equity investments at FVOCI	These assets are subsequently measured at fair value. Dividends are recognized as income in profit or loss unless the dividend clearly represents a recovery of the cost of the investment. Other net gains and losses are recognized in OCI and are never reclassified to profit or loss.

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:

• substantially all of the risks and rewards of ownership of the financial asset are transferred; or

• the Group neither transfers nor retains substantially all of the risks and rewards of ownership and it does not 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 – 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 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.

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

1) Hedge accounting, Continued

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

The Group reviews estimated residual values, expected useful lives, and depreciation methods annually at the end of each reporting date and adjusts, if appropriate. The change is accounted for as a change in an accounting estimate.

(8) 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	5 ~ 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.

(8) Intangible assets, Continued

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

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

(9) 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.

(10) 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.

(11) 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) Group 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.

(11) Leases, Continued

1) Group as a lessee, Continued

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;

• variable lease payments that depend on an index or a rate, initially measured using the index or rate as at the 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 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 on short-term leases and leases of low value assets as an expense on a straight-line basis over the lease term.

2) Group 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 KIFRS 1115 to allocate the consideration in the contract.

The Group applies derecognition and impairment requirements in KIFRS 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’.

(12) 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.

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).

(13) 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.

(14) 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 (assets) 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.

(15) 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.

(16) 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.

(17) 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.

(18) 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.

(19) 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.

(20) 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.

(21) 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.

(22) 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 and debentures, 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.

(23) 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.

(23) Income taxes, Continued

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 KIFRS 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.

(24) 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.

(25) 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 of business or geographic area of operations; or

• is a subsidiary acquired only for a purpose of 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.

6. Trade and Other Receivables, Continued

(2) Changes in the loss allowance on accounts receivable – trade measured at amortized costs for the years ended December 31, 2023 and 2022 are as follows:

(In millions of won)
	Beginning balance		Impair ment		Write-offs (*)			Collection of receivables previously written-off		Business combination		Ending balance
2023	W	234,923		37,906		(40,236	)		10,144		—		242,737
2022	W	238,881		27,053		(42,296	)		11,282		3		234,923

(*) The Group writes off the trade and other receivables that are determined to be uncollectable due to reasons 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 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 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, 2023 are as follows:

(In millions of won)
		Less than 6 months			6 months ~ 1 year			1 ~ 3 years			More than 3 years
Telecommunications service revenue	Expected credit loss rate		1.51	%		69.24	%		88.55	%		99.99	%
	Gross amount	W	1,467,781			48,329			139,925			21,545
	Loss allowance		22,130			33,461			123,906			21,542
Other revenue	Expected credit loss rate		2.30	%		28.27	%		53.39	%		93.51	%
	Gross amount	W	516,401			4,100			11,378			24,127
	Loss allowance		11,903			1,159			6,075			22,561

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, 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.

(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, 2023, floating-rate borrowings and debentures amount toW90,000 million andW386,820 million, respectively, and the Group has entered into interest rate swaps to hedge interest rate risk related to the floating-rate debentures. Therefore, profit before income tax for the year ended December 31, 2023 would not have been affected by the changes in interest rates of floating-rate debentures.

If the interest rate increases (decreases) 1%p with all other variables held constant, profit before income tax and equity for the year ended December 31, 2023 would change byW900 million in relation to the floating-rate borrowings which have not entered into interest rate swaps.

As of December 31, 2023, the floating-rate long-term payables – other areW1,290,225 million. If the interest rate increases (decreases) 1%p with all other variables held constant, profit before income tax and equity for the year ended December 31, 2023 would change byW12,902 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

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, thereby making it unclear when and how the transition to KOFR will take place.

Non-derivative financial liabilities

The Parent Company’s non-derivative financial liabilities subject to interest rate benchmark reform as of December 31, 2022 were floating-rate bonds indexed to USD LIBOR. The Group completed discussion with the counterparty about including the fallback clauses as of December 31, 2023.

Derivatives

Most of the Group’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 alternative 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 executed after January 25, 2021, and the transaction parties are required to adhere to ISDA protocol to include the same fallback clause into derivative contracts executed 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.

(iii) Price fluctuations risk

As of December 31, 2023, the Group holds equity instruments in an active trading market, exposing it to price fluctuation risk. Assuming all other variables remain constant, the impact on the Group’s profit before income tax and equity resulting from a 10% fluctuation in the per-share stock price of the equity securities for the year ended December 31, 2023 is as follows.

(In millions of won)
	December 31, 2023		December 31, 2022
Cash and cash equivalents	W	1,454,773		1,882,093

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 by 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, 2023 are included in note 6.

(ii) Debt investments

The credit risk arises from debt investments included inW295,309 million of financial instruments, andW1,055,102 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. Inputs used in such valuation methods include swap rate, interest rate, and risk premium, and the Group performs valuation using the inputs which are consistent with natures of assets and liabilities measured.

Interest rates used by the Group for the fair value measurement as of December 31, 2023 are as follows:

	Interest rate
Derivative instruments	2.18% ~ 6.25%
Borrowings and debentures	3.84% ~ 18.12%
Long-term payables – other	3.72% ~ 3.85%

We are independent of the Group in accordance with the ethical requirements that are relevant to our audit of ICFR 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 and Those Charged with Governance for ICFR

Management is responsible for designing, operating, and maintaining effective ICFR, and for its assessing the effectiveness of ICFR, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting.

Those charged with governance are responsible for overseeing the Group’s ICFR.

Auditor’s Responsibilities for the Audit of ICFR

Our responsibility is to express an opinion of the Group’s ICFR based on our audit. We conducted our audit in accordance with KSA. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective ICFR was maintained in all material respects.

An audit of the ICFR involves performing procedures to obtain audit evidence as to 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. An audit also includes testing and evaluating the design and operation of ICFR based on obtaining an understanding of ICFR and the assessed risk.

ICFR definition and Inherent Limitations

A company’s ICFR is implemented by those charged with governance, management, and other employees and is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (“KIFRS”). A company’s ICFR 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 consolidated financial statements in accordance with KIFRS, 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, ICFR may not prevent or detect misstatements of the financial statements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that ICFR 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 auditor’s report is Yoo, Jung Ho.

Independent Auditor’s Report

(English Translation of a Report Originally Issued in Korean)

The Shareholders and Board of Directors

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, 2023 and 2022, and the separate statements of income, comprehensive income, changes in equity and cash flows for each of the two years in the period ended December 31, 2023, and notes to the separate financial statements, including a summary of material accounting policies.

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, 2023 and 2022, and its separate financial performance and its separate cash flows for each for each of the two years in the period ended December 31, 2023 in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (“KIFRS”).

We also have audited the Company’s internal control over financial reporting as of December 31, 2023, based on the criteria established in Conceptual Framework for Designing and Operating Internal Control over Financial Reporting in accordance with the Korean Standards on Auditing (“KSA”) issued by the Operating Committee of internal control over financial reporting, and our report dated March 6, 2024 expressed an unqualified opinion thereon.

Basis for Opinion

We conducted our audits in accordance with KSA. Our responsibilities under those standards are further described in the Auditor’s 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.

Key Audit Matter

Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the separate financial statements of the current period. These matters were 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 these matters. For each matter below, our description of how our audit addressed the matter is provided in that context.

Cut-off of revenues from the wireless services

As described in notes 3 (21) and 27 to the separate financial statements, the Company’s revenue from the wireless services is recognized based on data from a complex array of information technology systems which process a significant volume of transactions with its customers. Furthermore, the transactions involve a variety of contractual terms from new subscriptions to deactivations or churn, and changes of rate plans during the period. Therefore, we have identified timing of revenue recognition related to the Company’s wireless services as a key audit matter. Related revenue from the wireless services amounted toW10,554,390 million in 2023.

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

• Inspecting major contracts with subscribers to assess whether the Company’s revenue recognition policies based on the terms and conditions as set out in the contracts, are consistent with reference to the requirements of KIFRS 1115;

• Testing internal controls relating to the timing of revenue recognition for the wireless services; and

• Evaluating the appropriateness of the timing of revenue recognition by recalculating the prorated revenue based on the subscribed rate plan and comparing it with the billing information.

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

Management is responsible for the preparation and fair presentation of the separate financial statements in accordance with KIFRS, 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.

Auditor’s 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 auditor’s 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 KSA 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 KSA, 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 or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.

• Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances.

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

• Conclude on the appropriateness of management’s use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Company’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor’s 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 the date of our auditor’s 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 disclosures, and whether the separate financial statements represent the underlying transactions and events in a manner that achieves fair presentation.

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 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 auditor’s 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 auditor’s report is Yoo, Jung Ho.

Accordingly, certain material subsequent events or circumstances may have occurred during the period from the date of independent auditor’s report date to the time this report is used.

		218,833,144		100.00

2. Basis of Preparation

These separate financial statements were prepared in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (“KIFRS”), as prescribed in the Act on External Audits of Stock Companies of Korea. The accompanying separate financial statements have been translated into English from Korean financial statements. In the event of any differences in interpreting the financial statements or the independent auditor’s report thereon, Korean version, which is used for regulatory reporting purposes, shall prevail.

These financial statements are separate financial statements prepared in accordance with KIFRS 1027, Separate Financial Statements, presented by a parent and an investor with joint control of or significant influence over an investee, in which the investments are accounted for at cost less impairment, if any.

The separate financial statements were authorized for issuance by the Board of Directors on February 2, 2024, which will be submitted for final approval at the shareholders’ meeting to be held on March 26, 2024.

(1) Basis of measurement

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

• derivative financial instruments measured at fair value;

• financial instruments measured at fair value through profit or loss (“FVTPL”);

• financial instruments measured at fair value through other comprehensive income (“FVOCI”);

• liabilities measured at fair value for cash-settled share-based payment arrangement; and

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

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 KIFRS 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 (21), and 6), property and equipment and intangible assets (notes 3 (7), (8), 10 and 14), impairment of goodwill (notes 3 (10) and 13), recognition of provision (notes 3 (15) and 17), measurement of defined benefit liabilities (notes 3 (14) and 18), transaction of derivative instruments (notes 3 (6) and 19) and recognition of deferred tax assets (liabilities) (notes 3 (23) and 31).

3) Fair value measurement

A number of the Company’s accounting policies and disclosures require the measurement of fair values, for both financial and non-financial assets and liabilities. The Company has 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 Company 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 Company assesses the evidence obtained from the third parties to support the conclusion that such valuations meet the requirements of KIFRS, 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;

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

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

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

Information about assumptions used for fair value measurements is included in note 19 and note 35.

3. Material Accounting Policies

The material accounting policies applied by the Company in the preparation of its separate financial statements in accordance with KIFRS are included below. Except for certain standards and amendments which are effective for annual periods beginning on or after January 1, 2023, the material 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, 2022. The Company has not early adopted any standards, and interpretations or amendments that have been issued but are not yet effective.

The new and amended standards and interpretations that are effective for annual periods beginning on or after January 1, 2023 are as follows. These amended standards had no material impact on the Company’s separate financial statements.

• Disclosure of Accounting Polices (Amendments to KIFRS 1001)

• Disclosures of Profit or Loss on Financial Liabilities with Conditions for Adjusting an Exercise Price (Amendments to KIFRS 1001)

• Definition of Accounting Estimates (Amendments to KIFRS 1008)

• Deferred Tax related to Assets and Liabilities Arising from a Single Transaction (Amendments to KIFRS 1012)

• KIFRS 1117 Insurance Contracts and its amendments

• International tax reform – Pillar Two model rules (Amendments to KIFRS 1012)

The Pillar Two model rules is scheduled to take effect for the Company’s fiscal year beginning January 1, 2024. As the Company falls within the scope of the enacted Pillar Two model rules, it has assessed the potential exposure to Pillar Two income tax. The assessment of potential exposure to Pillar Two income tax is based on the most recent tax returns of the Company’s ultimate controlling entity group, country-by-country reporting, and financial statements. The Company expects that the exposure to Pillar Two income tax will be immaterial.

(1) Operating segments

The Company presents disclosures relating to operating segments on its consolidated financial statements in accordance with KIFRS 1108, Operating Segments, and such disclosures are not separately disclosed on these separate financial statements.

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

These separate financial statements are prepared and presented in accordance with KIFRS 1027, Separate Financial Statements. The Company applies the cost method to investments in subsidiaries, associates and joint ventures in accordance with KIFRS 1027. Dividends from subsidiaries, associates, and joint ventures are recognized in profit or loss when the right to receive the dividends is established.

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 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 Company 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 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

• its contractual terms give rise to cash flows that are solely payments of principal and interest on the principal amount outstanding on specified dates.

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

• it is held within a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets; and

• its contractual terms give rise to cash flows that are solely payments of principal and interest on the principal amount outstanding on specified dates.

On initial recognition of an equity investment that is not held for trading, the 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 profit or loss. Any gain or loss on derecognition is recognized in profit or loss.
Debt investments at FVOCI	These assets are subsequently measured at fair value. Interest income calculated using the effective interest method, foreign exchange gains and losses and impairment are recognized in profit or loss. Other net gains and losses are recognized in OCI. On derecognition, gains and losses accumulated in OCI are reclassified to profit or loss.
Equity investments at FVOCI	These assets are subsequently measured at fair value. Dividends are recognized as income in profit or loss unless the dividend clearly represents a recovery of the cost of the investment. Other net gains and losses are recognized in OCI and are never reclassified to profit or loss.

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.

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 Company expects to receive).

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.

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

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:

• substantially all of the risks and rewards of ownership of the financial asset are transferred; or

• the Company neither transfers nor retains substantially all of the risks and rewards of ownership and it does not 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 – 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.

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 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 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.

1) Hedge accounting, Continued

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.

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 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.

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).

(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

The Company reviews estimated residual values, expected useful lives, and depreciation methods annually at the end of each reporting date and adjusts, if appropriate. The change is accounted for as a change in an accounting estimate.

(8) 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	5 ~ 10
Land usage rights	5
Industrial rights	5, 10
Facility usage rights	10, 20
Other	3 ~ 20

Amortization periods and the amortization methods for intangible assets with finite useful lives are reviewed at the end of each reporting period. The useful lives of intangible assets that are not being amortized are reviewed at the end of each reporting period to determine whether events and circumstances continue to support indefinite useful life assessments for those assets. Changes, 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 Company intends to and has sufficient resources to complete development and to use or sell the asset. Other development expenditures are recognized in profit or loss as incurred.

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

(9) 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 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.

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.

(10) 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.

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.

(11) 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) Company 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 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 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.

(11) Leases, Continued

1) Company 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.

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 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 on short-term leases and leases of low value assets as an expense on a straight-line basis over the lease term.

2) Company 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 KIFRS 1115 to allocate the consideration in the contract.

The Company applies derecognition and impairment requirements in KIFRS 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’.

(12)  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.

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).

(13)  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

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 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.

(14)  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 (assets) 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.

(15)  Provisions

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

The risks and uncertainties that inevitably surround many events and circumstances are taken into account in reaching the best estimate of a provision. 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.

(16)  Emissions Rights

The Company 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 Company 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.

(17)  Transactions in foreign currencies

Transactions in foreign currencies are translated to the functional currency of the Company at exchange rates at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are retranslated to the functional currency using the 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.

(18)  Share capital

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

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

(19)  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.

(20)   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.

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.

(21)  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.

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 and debentures, 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.

(23)  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 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.

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 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 KIFRS 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.

(24)  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.

(25)  Standards issued but not yet effective

The new and amended standards and interpretations that are issued, but not yet effective for annual period beginning after January 1, 2023 are disclosed below. The following amendments are not expected to have a material impact on the Company’s separate financial statements.

• Classification of Liabilities as Current or Non-current (Amendments to KIFRS 1001).

(3) The Company applies the practical expedient that allows the Company to estimate the loss allowance for accounts 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 Company uses its historical credit loss experience over the past three 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, 2023 are as follows:

(In millions of won)
		Less than 6 months			6 months ~ 1 year			1 ~ 3 years			More than 3 years
Telecommunications service revenue	Expected credit loss rate		0.46	%		48.91	%		73.36	%		99.98	%
	Gross amount	W	1,144,931			18,062			47,666			17,412
	Loss allowance		5,288			8,835			34,970			17,409
Other revenue	Expected credit loss rate		2.20	%		50.30	%		56.58	%		97.32	%
	Gross amount	W	336,220			2,199			8,583			14,789
	Loss allowance		7,389			1,106			4,856			14,392

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.

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, interest rates and price fluctuations. 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, long-term investment securities, accounts receivable – trade and others, etc. Financial liabilities consist of accounts payable – other and others, borrowings, debentures, lease liabilities and others.

1) Market risk

(i) Currency risk

The Company’s currency risk is mainly related to changes in recognized assets and liabilities due to exchange rate fluctuations. If the Company determines that it is necessary to hedge currency risk for business purposes, the Company manages currency risk by using currency swaps, etc. Currency risk occurs 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, 2023 are as follows:

(In millions of won, thousands of foreign currencies)
	Assets				Liabilities
	Foreign currencies		Won equivalent		Foreign currencies		Won equivalent
USD		24,551	W	31,656		706,572	W	911,054
EUR		654		933		3		4
Others		—		336		—		—
			W	32,925			W	911,058

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

As of December 31, 2023, a hypothetical change in exchange rates by 10% would have increased (decreased) the Company’s profit before income tax and equity as follows:

(In millions of won)
	Profit before income tax					Equity
	If increased by 10%		If decreased by 10%			If increased by 10%		If decreased by 10%

(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, 2023, floating-rate borrowings and debentures amount toW40,000 million andW386,820 million, respectively, and the Company has entered into interest rate swaps to hedge interest rate risk related to the floating-rate debentures. Therefore, profit before income tax for the year ended December 31, 2023 would not have been affected by the changes in interest rates of floating-rate debentures. If the interest rate increases (decreases) by 1%p with all other variables held constant, profit before income tax and equity for the year ended December 31, 2023 would change byW400 million in relation to the floating-rate borrowings which have not entered into interest rate swaps.

As of December 31, 2023, the floating-rate long-term payables – other areW1,290,225 million. If the interest rate increases (decreases) by 1%p with all other variables held constant, profit before income tax and equity for the year ended December 31, 2023, would change byW12,902 million in relation to the floating-rate long-term payables – other that are exposed to interest rate risk.

Non-derivative financial liabilities

The Company’s non-derivative financial liabilities subject to interest rate benchmark reform as of December 31, 2022 were floating-rate bonds indexed to USD LIBOR. The Company completed discussion with the counterparty about including the fallback clauses as of December 31, 2023.

Derivatives

The Company’s derivative instruments designated as cash flow hedge are governed by contracts based on the International Swaps and Derivatives Association (“ISDA”) 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 are required to adhere to ISDA protocol to include the same fallback clause into derivative contracts executed 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.

(iii) Price fluctuations risk

As of December 31, 2023, the Company holds equity instruments in an active trading market, exposing it to price fluctuation risk. Assuming all other variables remain constant, the impact on the Company’s profit before income tax and equity resulting from a 10% fluctuation in the per-share stock price of the equity securities for the year ended December 31, 2023 is as follows.

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 by 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.

2) Credit risk, Continued

(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, 2023 are included in note 5.

(ii) Debt investments

The credit risk arises from debt investments included inW186,718 million of financial instruments, andW886,377 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, 2023 are as follows:

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

The impairment on cash and cash equivalents was measured using a 12-month expected credit loss, taking into account the short-term exposure. The Company assessed the risk of cash and cash equivalents based on the counterparty’s external credit rating, determining it to be low.

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 in 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, 2023 are as follows:

	Interest rate
Derivative instruments		3.80% ~ 4.43%
Borrowings and debentures		3.84% ~ 3.84%
Long-term payables – other		3.72% ~ 3.85%

Independent auditor’s report on Internal Control over Financial Reporting

(Based on a report originally issued in Korean)

SK Telecom Co., Ltd.:

The Shareholders and Board of Directors

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting (“ICFR”) of SK Telecom Co., Ltd.’s (the “Company”) based on the Conceptual Framework for Designing and Operating ICFR (“ICFR Design and Operation Framework”) established by the Operating Committee of ICFR in Korea (the “ICFR Committee”) as of December 31, 2023.

In our opinion, the Company’s ICFR has been effectively designed and operated, in all material respects, as of December 31, 2023, in accordance with the ICFR Design and Operation Framework.

We also have audited, in accordance with Korean Standards on Auditing (“KSA”), the separate statement of financial position as of December 31, 2023, the separate statements of income, comprehensive income, changes in equity, and cash flows for the year then ended, and notes to the separate financial statements, including a summary of material accounting policies, of the Company, and our report dated March 6, 2024 expressed an unqualified opinion thereon.

Basis for Opinion on ICFR

We conducted our audit in accordance with KSA. Our responsibilities under those standards are further described in the Auditor’s Responsibilities for the Audit of ICFR section of our report. We are independent of the Company in accordance with the ethical requirements that are relevant to our audit of ICFR 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 and Those Charged with Governance for ICFR

Management is responsible for designing, operating, and maintaining effective ICFR, and for its assessing the effectiveness of ICFR, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting.

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

Auditor’s Responsibilities for the Audit of ICFR

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

An audit of ICFR involves performing procedures to obtain audit evidence as to 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 An audit also includes testing and evaluating the design and operation of ICFR based on obtaining an understanding of ICFR and the assessed risk.

112

ICFR definition and Inherent Limitations

A company’s ICFR is implemented by those charged with governance, management, and other employees and is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (“KIFRS”). A company’s ICFR 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 KIFRS, 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, ICFR may not prevent, or detect misstatements of the financial statements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that ICFR 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 auditor’s report is Yoo, Jung Ho.

March 6, 2024

This report is effective as of March 6, 2024, the independent auditor’s report date. Accordingly, certain material subsequent events or circumstances may have occurred during the period from the auditor’s report date to the time this report is used.
