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

A. Industry Characteristics

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

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

C. Domestic and Overseas Market Conditions

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

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

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

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

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

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

D. Competitive Strengths

The Company successfully completed the Spin-off of SK Square Co., Ltd. (“SK Square”) from SK Telecom (the “Spin-off”) in 2021 to maximize shareholder value and launched “SKT 2.0.” Concurrently, the Company reorganized its business to center around five major business segments and is seeking maximization of overall corporate value by establishing and executing strategies optimized for each business segment and pursuing growth in each segment. For the three months ended March 31, 2022, the Company recorded Won 4.28 trillion in operating revenue and Won 4.32 trillion in operating profit on a consolidated basis and Won 3.08 trillion in operating revenue and Won 0.36 trillion in operating profit for the period on a separate basis. The Company is continuing to improve sales growth and profit margin by leveraging its competitiveness in the 5G market and secured 10.88 million 5G subscribers as of March 31, 2022. The Company was also ranked as the top service provider in the MNO service sector in the National Customer Satisfaction Index (“NCSI”) in April 2022 and became the first across all industries in Korea to rank first for 25 consecutive years since the commencement of NCSI in 1998. The Company is actively striving to achieve tangible growth in new businesses in addition to maintaining its competitiveness in the fixed-line and wireless businesses.

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

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

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

[Fixed-line Business]

For the three months ended March 31, 2022, SK Broadband Co., Ltd. (“SK Broadband”) recorded Won 1.03 trillion in revenue on a consolidated basis, which represented a 6.1% increase from Won 967.0 billion for the three months ended March 31, 2021. The sales growth was primarily attributable to continued expansion of the subscriber base, increase in sales of media platforms including home shopping and advertisements, business acquisition of SK Telink and growth of our B2B business.

The Company’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 and Internet data center services. For the three months ended March 31, 2022, the media business segment recorded Won 470.4 billion in revenue, which represented a 3.9% increase compared to the three months ended March 31, 2021. For the three months ended March 31, 2022, the fixed-line business segment recorded Won 555.6 billion in revenue, which represented an 8% increase compared to the three months ended March 31, 2021.

A. Industry Characteristics

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

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

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

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

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

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

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

C.Cyclical Nature and Seasonality

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

SK Broadband 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, SK Broadband principally 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 SK Broadband, KT and LG U+.

[Other Businesses]

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

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

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 is committed to fulfilling its social obligations with a sense of responsibility for its impact on the society and the environment on a company-wide basis. Under the vision of “realizing a sustainable future based on ICT,” 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, in December 2020, the Company was one of the first companies in Korea to join the RE100 (Renewable Energy 100%) initiative, which aims to source 100% of its energy needs from renewable energy sources by 2050. 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 addition, SK Broadband continues to invest in environment-friendly facilities for its data centers and improve the stability and efficiency of its services.

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.

Report on review of interim consolidated financial statements

The Shareholders and Board of Directors

SK TelecomCo., Ltd.

Report on the financial statements

We have reviewed the accompanying interim consolidated financial statements of SK Telecom Co., Ltd. and its subsidiaries (the “Group”), which comprise the interim consolidated statement of financial position as of March 31, 2022, and the related interim consolidated statements of profit or loss, comprehensive income, changes in equity and cash flows for the three-month period then ended, and a summary of significant accounting policies and other explanatory information.

Management’s responsibility for the interim consolidated financial statements

Management is responsible for the preparation and fair presentation of these interim consolidated financial statements in accordance with Korean International Financial Reporting Standards (“K-IFRS”) 1034 Interim Financial Reporting, and for such internal controls as management determines is necessary to enable the preparation of interim consolidated financial statements that are free from material misstatement, whether due to fraud or error.

Auditor’s responsibility

Our responsibility is to express a conclusion on these interim consolidated financial statements based on our review.

We conducted our review in accordance with the review standards for interim financial statements in the Republic of Korea. A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with Korean Auditing Standards (“KGAAS”) and, consequently, does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe that the accompanying interim consolidated financial statements are not prepared fairly, in all material respects, in accordance with K-IFRS 1034 Interim FinancialReporting.

Emphasis of matter

We draw to attention to Notes 3 and 36, which describes that pursuant to the resolution of shareholders’ meeting held on October 12, 2021, the SK Telecom Co., Ltd. completed the spin-off of certain businesses as of November 1, 2021. The businesses spun off are presented as discontinued operations, and the comparative interim consolidated statement of profit or loss for the three-month period ended March 31, 2021 and related notes have been restated to present the discontinued operations separately from continuing operations. Our conclusion is not modified in respect of this matter.

Notes to the Interim Consolidated Financial Statements

For the three-month periods ended March 31, 2022 and 2021 (Unaudited)

2.	Basis of Preparation
(1)	Statement of compliance
---	---

These interim condensed consolidated financial statements were prepared in accordance with Korean International Financial Reporting Standard (“K-IFRS”) 1034 Interim Financial Reporting as part of the period covered by the Group’s K-IFRS annual financial statements. Selected explanatory notes are included to explain events and transactions that are significant to an understanding of the changes in financial position and performance of the Group since December 31, 2021. These interim consolidated financial statements do not include all of the disclosures required for full annual financial statements.

(2)	Use of estimates and judgments

1) Critical judgments, assumptions and estimation uncertainties

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

In preparing these interim consolidated financial statements, the significant judgments made by management in applying the Group’s accounting policies and the key sources of estimation uncertainty were the same as those that applied to the consolidated financial statements as of and for the year ended December 31, 2021.

(2)	Use of estimates and judgments, Continued
---	---

2) 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 established policies and processes with respect to the measurement of fair values, including Level 3 fair values, and the measurement of fair values is reviewed and is directly reported to the finance executives.

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

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

✓ Level 1:	quoted prices (unadjusted) in active markets for identical assets or liabilities;
✓ 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 30.

3.	Significant Accounting Policies

The significant accounting policies applied by the Group in these interim 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, 2021. The Group has not early applied the new and revised K-IFRS and interpretations that have been issued but are not yet effective.

The following new and amended K-IFRS and interpretations are effective from January 1, 2022, initially, but these amended standards are not expected to have a significant impact on the Group’s interim consolidated financial statements.

•	Onerous Contracts – Cost of Fulfilling a Contract (Amendments to<br>K-IFRS 1037).
•	Reference to Conceptual Framework (Amendments to K-IFRS 1103).<br>
---	---
•	Property, Plant and Equipment: Proceeds before Intended Use (Amendments to<br>K-IFRS 1016).
---	---
•	Annual Improvements to K-IFRS 2018-2020.
---	---

Meanwhile, as described in note 36, the Parent Company carried out spin-off of its businesses of managing investments in semiconductor, New Information and Communication Technologies(“ICT”) and other businesses and making new investments pursuant to the resolution of the Board of Directors on June 10, 2021 and approval of shareholders’ meeting on October 12, 2021. The Group has applied K-IFRS 1105 Non-current Assets Held for Sale and Discontinued Operations, and accordingly, presented profit or loss of the spin-off business as discontinued operations. The comparative interim consolidated statement of profit or loss for the three-month period ended March 31, 2021 and related notes have been restated to present the discontinued operations separately from continuing operations.

4.	Operating Segments, Continued
(1)	Segment information for the three-month periods ended March 31, 2022 and 2021 are as follows,<br>Continued:
---	---

(*) The Parent Company carried out spin-off of its businesses of managing investments in semiconductor, New Information and Communication Technologies(“ICT”) and other business and making new investments for the year ended December 31, 2021. Accordingly, the Group reclassified SK stoa Co., Ltd. from Commerce Services segment to Others segment.

The Group has restated the previously reported segment information for the three-month period ended March 31, 2021 to reflect reclassification of operating segments due to the spin-off.

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

No single customer contributed 10% or more to the Group’s total revenue for the three-month periods ended March 31, 2022 and 2021.

	~~W~~	365,063		7,420			(4,983	)		6,515		374,015
(*)	The Group writes off trade and other receivables that are determined to be uncollectable due to reasons, such<br>as termination of operations or bankruptcy.
---	---
(3)	The Group applies the practical expedient that allows the Group to estimate the loss allowance for accounts<br>receivable – trade at an amount equal to the lifetime expected credit losses. The expected credit losses include the forward-looking information. To make the assessment, the Group uses its historical credit loss experience over the past three<br>years and classifies accounts receivable – trade by their credit risk characteristics and days overdue.
---	---

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

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

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

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

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

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

Monetary assets and liabilities denominated in foreign currencies as of March 31, 2022 are as follows:

(In millions of won, thousands of foreign currencies)

All values are in US Dollars.

In addition, the Group has entered into currency swaps to hedge against currency risk related to foreign currency borrowings and debentures.

As of March 31, 2022, a hypothetical change in exchange rates by 10% would have increased (decreased) the Group’s profit before income tax as follows:

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

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

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

As of March 31, 2022, floating-rate borrowings and debentures amount to ~~W~~31,250 million and ~~W~~363,240 million, respectively, and the Group has entered into interest rate swaps to hedge interest rate risk related to the floating-rate borrowings and debentures. Therefore, profit before income taxes for the three-month period ended March 31, 2022 would not have been affected by the changes in interest rates of floating-rate borrowings and debentures.

As of March 31, 2022, the floating-rate long-term payables – other are ~~W~~1,690,470 million. If the interest rate increases (decreases) 1%p with all other variables held constant, profit before income taxes for the three-month period ended March 31, 2022, would change by ~~W~~4,226 million in relation to the floating-rate long-term payables – other that are exposed to interest rate risk.

Interest rate benchmark reform and associated risks

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

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

The Group’s financial instruments exposed to the risk arising from interest rate benchmark reform as of March 31, 2022 are indexed to the USD LIBOR. The Group is exposed to legal risk to amend the terms of contracts on the financial instruments subject to interest rate benchmark reform as well as process and operation risks to manage such amendments. In addition, the Group is exposed to the risk of monitoring the market trend regarding the alternative interest rate and establishing the corresponding risk management strategy. If the IBOR is designated as the hedged item, the Group is required to replace it to an alternative benchmark interest and review the effects on the hedging relationship. In addition, the Group is exposed to the risk of minimizing hedge ineffectiveness by aligning the method and timing of the transition to the alternative benchmark interest applied to the hedged item and the hedging instrument.

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

Non-derivative financial liabilities

The Parent Company’s non-derivative financial liabilities subject to interest rate benchmark reform as of December 31, 2021 were floating-rate bonds indexed to USD LIBOR. As explained above, the Group is discussing with the counterparty about including the fallback clauses as of March 31, 2022.

Derivatives

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

Hedge accounting

The Group’s hedged items and hedging instruments as of March 31, 2022 are indexed to USD LIBOR. These benchmark rates are quoted each day, and the IBOR cash flows are exchanged with counterparties as usual.

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

The Group establishes a loss allowance in respect of accounts receivable – trade. 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. Also, the Group’s credit risk can arise from transactions with financial institutions related to its cash and cash equivalents, financial instruments and derivatives. To minimize such risk, the Group has a policy to deal only with financial institutions with high credit ratings. The amount of maximum exposure to credit risk of the Group is the carrying amount of financial assets as of March 31, 2022.

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 to 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 March 31, 2022 are as follows:

	Interest rate
Derivative instruments	0.32% ~ 3.59%
Borrowings and debentures	1.74% ~ 3.30%
Long-term payables – other	2.43% ~ 3.16%

In preparing these interim separate financial statements, the significant judgments made by management in applying the Company’s accounting policies and the key sources of estimation uncertainty were the same as those that applied to the separate financial statements as of and for the year ended December 31, 2021.

2) 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 K-IFRS, including the level in the fair value hierarchy in which such valuations should be classified.

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

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

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

Information about assumptions used for fair value measurements are included in note 28.

3.	Significant Accounting Policies

The significant accounting policies applied by the Company in these interim 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, 2021, except for the adoption of new and revised K-IFRS applied from January 1, 2022, which are summarized below. The Company has not early applied the new and revised K-IFRS and interpretations that have been issued but are not yet effective.

•	Onerous Contracts – Cost of Fulfilling a Contract (Amendments to<br>K-IFRS 1037).
•	Reference to Conceptual Framework (Amendments to K-IFRS 1103).<br>
---	---
•	Property, Plant and Equipment: Proceeds before Intended Use (Amendments to<br>K-IFRS 1016).
---	---
•	Annual Improvements to K-IFRS 2018-2020.

	~~W~~	178,478		2,197		(449	)		3,231		183,457
(*)	The Company writes off trade and other receivables that are determined to be uncollectable due to reasons such<br>as termination of operations or bankruptcy.
---	---
(3)	The Company applies the practical expedient that allows the Company to estimate the loss allowance for accounts<br>receivable – trade at an amount equal to the lifetime expected credit losses. The expected credit losses include the forward-looking information. To make the assessment, the Company uses its historical credit loss experience over the past three<br>years and classifies accounts receivable – trade by their credit risk characteristics and days overdue.
---	---

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 ratings. While the contract assets are subject to the impairment requirements, no significant expected credit loss has been identified.

(1)	Financial risk management
---	---

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

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

1) Market risk

(i) Currency risk

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

Monetary assets and liabilities denominated in foreign currencies as of March 31, 2022 are as follows:

(In millions of won, thousands of foreign currencies)
				Liabilities
		Won equivalent		Foreign currencies		Won equivalent
	18,979	~~W~~	22,980		1,215,438	~~W~~	1,471,652
	110		148		—		—
Others	—		171		—		21
		~~W~~	23,299			~~W~~	1,471,673

All values are in US Dollars.

In addition, the Company has entered into currency swaps to hedge against currency risk related to foreign currency borrowings and debentures.

As of March 31, 2022, a hypothetical change in exchange rates by 10% would have increased (decreased) the Company’s profit before income tax as follows:

(In millions of won)
		If decreased by 10%
	483		(483	)
	15		(15	)
Others	15		(15	)
	513		(513	)

All values are in Euros.

1) Market risk, Continued

(ii) Interest rate risk

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

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

As of March 31, 2022, floating-rate debentures amount to ~~W~~363,240 million, and the Company has entered into interest rate swaps to hedge interest rate risk related to the floating-rate debentures. Therefore, profit before income taxes for the three-month period ended March 31, 2022 would not have been affected by the changes in interest rates of floating-rate debentures.

Interest rate benchmark reform andassociated risks

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

Interest rate benchmark reform and associated risks, Continued

The Company’s financial instruments exposed to the risk arising from interest rate benchmark reform as of March 31, 2022 are indexed to the USD LIBOR. The Company is exposed to legal risk to amend the terms of contracts on the financial instruments subject to interest rate benchmark reform as well as process and operation risks to manage such amendments. In addition, the Company is exposed to the risk of monitoring the market trend regarding the alternative interest rate and establishing the corresponding risk management strategy. If the IBOR is designated as the hedged item, the Company is required to replace it to an alternative benchmark interest and review the effects on the hedging relationship. In addition, the Company is exposed to the risk of minimizing hedge ineffectiveness by aligning the method and timing of the transition to the alternative benchmark interest applied to the hedged item and the hedging instrument.

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

Non-derivative financial liabilities

The Company’s non-derivative financial liabilities subject to interest rate benchmark reform as of December 31, 2021 were floating-rate bonds indexed to USD LIBOR. As explained above, the Company is discussing with the counterparty about including the fallback clauses as of March 31, 2022.

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

Hedge accounting

The Company’s hedged items and hedging instruments as of March 31, 2022 are indexed to USD LIBOR. These benchmark rates are quoted each day, and the IBOR cash flows are exchanged with counterparties as usual.

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

The Company establishes a loss allowance in respect of accounts receivable – trade. 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. Also, the Company’s credit risk can arise from transactions with financial institutions related to its cash and cash equivalents, financial instruments and derivatives. To minimize such risk, the Company has a policy to deal only with financial institutions with high credit ratings.

The Company’s maximum exposure to credit risk is equal to each financial asset’s carrying amount as of March 31, 2022.

---	---

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

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

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

Interest rates used by the Company for the fair value measurement as of March 31, 2022 are as follows:

	Interest rate
Derivative instruments	0.32% ~ 3.23%
Borrowings and debentures	1.74% ~ 3.11%
Long-term payables – other	2.43% ~ 3.16%
