[Wireless Business]

A. Industry Characteristics

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

The Korean mobile communication market is considered to have reached its maturation stage with more than a 100% penetration rate. However, the Korean mobile communications market continues to improve in the quality of services with the help of advances in network-related technology and the development of highly advanced LTE-A, LTE and 3G smartphones which enable the provision of convergence services for multimedia contents, mobile commerce, telematics, new media and other related services. In addition, through the commercialization of LTE network in July 2011 and LTE-A network in June 2013, B2B businesses, such as the corporate connected workforce business which can directly contribute to an enhancement in productivity, are expected to grow rapidly.

In the first half of 2014, wideband LTE-A service was commercialized and on December 29, 2014, tri-band LTE-A service with a maximum speed of 300 Mbps was also commercialized. Since June 2017, through the commercialization of 5band CA technology, which is considered the final stage of LTE development, we have provided 4.5G service at the speed of 700Mbps to 900Mbps. Such achievements were the building blocks towards the Companys LTE penetration reaching 75.7% as of December 31, 2017.

Sales revenue related to data services is expected to increase due to the increasing popularity of smartphones and high-speed wireless networks. There is also a growing importance to the business-to-business segment, which creates added value by selling and developing various solutions. Seasonal and economic fluctuations have much less impact on the Korean mobile communication market compared to other industries.

D. Business Overview and Competitive Strengths

The Company is seeking to transform itself from a telecommunications service provider into a comprehensive ICT service provider. It has continued to innovate the scope of its services and achieved strong growth in subscribers amid fierce competition and rate cuts. As a result, in 2017, the Company recorded Won 17,520 billion in revenue and Won 1,537 billion in operating income on a consolidated basis and Won 12,468 billion in revenue and Won 1,698 billion in operating income on a separate basis. In particular, the number of subscribers subscribing to Band Data plans, which was launched in the second quarter of 2015, has continued to steadily increase in 2017, which in turn led to an increase in data usage. The success of Luna, a smartphone launched in September 2015 that was designed to run exclusively on the Companys networks, led to the launch of various other relatively low-priced devices and became an example of successfully targeting a niche market.

By continuing to be innovative in developing core competencies, the Company has more firmly established its position as the market leader in wireless telecommunications. The competitive environment of the wireless telecommunications industry has become more focused on retention. In 2017, the average monthly churn rate was 1.4%. The number of subscribers (including MVNO subscribers) as of December 31, 2017 was 30.2 million, an increase of approximately 600,000 since December 31, 2016. In particular, the number of smartphone subscribers as of December 31, 2017, was 23.0 million, an increase of approximately 1.1 million since December 31, 2016, propelled by 22.9 million LTE subscribers, solidifying the Companys market leadership. In addition, the Company continued to sell products targeted towards second devices such as the T Kids phone Joon and T Outdoor, which the Company believes shows a level of demand that can potentially lead to growth of the lifestyle enhancement platform.

Following the launch of commercial LTE services in July 2011, the Company became the first telecommunications service provider in the world to launch commercial wideband LTE-A services in June 2014. The Company launched tri-band LTE-A services in December 2014 and 5band 4.5G services in June 2017. By launching various high quality services utilizing the LTE-A and wideband LTE networks such as group video conference call services and full high definition mobile IPTV streaming services, the Company plans to provide an innovative user experience, enhance customer satisfaction and increase profitability.

The Company has proved that it has superior network quality compared to its competitors according to the Korea Communications Commission quality evaluations. The Company has also proved to be the leader in Koreas top three customer satisfaction indices: according to the National Customer Satisfaction Index, Korean Customer Satisfaction Index and Korean Standard Service Quality Index, the Company has continued to hold the leading position for 21 years, 20 years and 18 years, respectively. The Company received the highest level of evaluation in 2016 by the Korea Commission for Corporate Partnership for the fifth consecutive year and was selected for the commissions Honored Corporation Award, demonstrating the Companys efforts to be fair and law-abiding in its path towards creating a New ICT ecosystem.

SK Telink, a consolidated subsidiary of the Company, expanded its operations to the MVNO business based on its technical expertise and know-how obtained in its international telecommunications business and launched 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. An MVNO leases the networks of an MNO and provides wireless telecommunication services under its own brand and fee structure, without owning telecommunication networks or frequencies.

Network O&S, a subsidiary of the Company responsible for the operation of the Companys 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.

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

[Fixed-line Business]

A. Industry Characteristics

The Korean fixed-line services industry is marked by a relatively low level of economic sensitivity and high level of market concentration, as the government is highly selective in granting telecommunications business licenses. 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+. Growing competition within the industry has promoted rapid technological evolution, including the convergence of fixed-line and wireless services, as well as broadcasting and telecommunications. In general, the fixed-line and wireless services markets have been characterized by relatively high profitability, cash flows and financial stability.

In the backdrop of increasing regulation in the fixed-line industry, competition to provide Giga services has intensified and the growth of high-speed internet subscribers has slowed. It is currently expected that the rate of increase of IPTV subscribers will decrease, among others, due to the conversion to digital broadcasting. In order to differentiate itself from its competitors, the Company believes that it will need to provide customers with high quality media content on its IPTV platform. Additionally, the Company expects increased demand for ultra-high definition broadcasting. Such changing trends of broadcasting consumption present opportunities to incorporate the Companys IoT, cloud and big data technologies into the Companys home platform business to achieve new growth. The Company plans to increase its subscriber base by providing differentiated services and focusing on marketing strategies centered around high value services such as Giga services and ultra-high definition broadcasting services.

C. Cyclical Nature and Seasonality

High-speed Internet, fixed-line telephone and IPTV services are mature markets that are comparatively less sensitive to cyclical economic changes as such services have become more of a necessity and the market has matured. 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.

The number of IPTV subscribers was taken from data announced by the MSIT on November 9, 2017, and the number of IPTV subscribers as of December 31, 2017, was calculated using the average number of subscribers for the first six months of 2017.

E. Business Overview and Competitive Strengths

For the year ended December 31, 2017, we recorded Won 3,526 billion in revenue, Won 127 billion in operating income and Won 30 billion in profit for the period for our fixed-line business. Revenue increased primarily due to an increase in revenue from IPTV and we achieved stable growth in profitability despite investments made for the improvement of our network infrastructure and the strengthening of our media platform. As of December 31, 2017, the number of subscribers to each of our high-speed internet, fixed-line telephones (including VoIP) and IPTV services was 5.44 million, 4.11 million and 4.37 million, respectively. In addition, our domestic and international credit ratings for SK Broadband remain unchanged from last year, and we maintained a stable financial position throughout 2017 by improving profitability.

The high-speed internet business is a relatively mature market and the number of our new subscribers decreased in 2017. However, we continued to expand growth in premium services, mainly our Giga internet service. By enhancing the efficiency of our distribution channel and upgrading our customer retention system, we solidified our market position and continued to reduce churn rates.

While the number of new IPTV subscribers has decreased due to the increased proportion of pay TV subscribers and high-speed internet users that have converted to digital broadcasting, we achieved high revenue growth with an increase in the number of subscribers of premium services including our ultra-high definition broadcasting service, the increase in sales of paid content and expansion of our platform businesses such as media advertisement. In addition, in the face of diversified customer needs and the growing trend of convergence services, we expanded efforts to differentiate content, adopt big data analysis technologies and reinforce competitiveness in business areas such as artificial intelligence. We believe that such competition in services present growth opportunities for our home platform business, particularly in connection with the fourth industrial revolution. By upgrading our user interface, strengthening content competitiveness and customer satisfaction, we expanded our market position and shifted toward a subscriber base with higher average revenue per subscriber in areas such as ultra-high definition services. In addition, we increased the platform value of Oksusu by focusing on original content competitiveness while launching a PC web version and restructuring its user interface.

In our corporate business, we employed customer-centered marketing strategies to target differentiated markets to expand our platform business and will continue efforts to maximize platform potential. In addition, we increased profitability by focusing on our core line-based business and also expanded our growth businesses.

SK Telink, a provider of international telecommunications service, has been able to establish itself as a market leader as a result of its affordable pricing, proactive marketing and the quality of its services. It launched a mobile phone-based international calling service under the brand name 00700 in 1998, creating a new niche market within the long-distance telephony market that was otherwise dominated by existing service providers. In 2003, SK Telink was designated a common carrier for international calling services, which allowed the Company to expand its international calling services to fixed-line international calling services. In 2005, SK Telink obtained a license to operate VoIP services and local calling value-added services to develop into a versatile fixed-line telecommunications service provider. SK Telink plans to strategically target the convergence of wireless and fixed-line telecommunications and strengthen its existing business, including international and long-distance calling services, value-added services for local calling and B2B services, and video conference call services while aiming to satisfy the diverse needs of customers by providing quality solutions at reasonable prices.

[Other Business]

A. Industry Characteristics

As the number of smartphones distributed in Korea exceeds 40 million, the growth in various mobile devices has spurred the rise of the service provider with a strong platform business as the leader in the ICT market. It is becoming increasingly important to enhance competitiveness by building a platform with large data capacity to handle the increase in data transmission.

A platform business acts as an intermediary by promoting interactions among various customer groups, thereby generating new values. It is important for a platform business to continually attract subscribers and users and to create an ecosystem with certain lock-in effects. A platform can exist in various forms, including as a technological standard (iOS, Android OS), a subscriber-based service platform (Facebook, Twitter) or a marketplace (Amazon, Onestore). Platform businesses are evolving and expanding globally.

A platform business has strong growth potential due to its connectivity with related services and ease of global expansion. Apple became a world-leading smartphone producer based on its innovative design and the competitive strength of its App Store platform. Google has created a new ecosystem of long-tail advertising by attracting millions of third parties to its advertising platform, as well as showing strong growth in mobile markets with its competitive platform based on Android OS. It is becoming increasingly important to enhance competitiveness through a database that can register and analyze purchase patterns of customers across all areas and a platform with large data capacity with which to utilize this database and provide differentiated services to customers.

B. Growth Potential

The scope and value generated by the platform business, including application and content marketplaces and N-screen services, continue to increase as smartphones and tablet computers become more popular and the bandwidth and speed of network infrastructure improve. As the wireless network evolves to LTE, business opportunities for the platform business exist, including multimedia streaming, N-screen service based on cloud technology and high-definition location-based services. Since the platform business realizes profit by connecting with advertisements or commerce sites after building a critical mass of subscribers and traffic, the recent growth in the advertising and commerce markets is expected to present an opportunity for platform businesses. The importance of building a platform with large data capacity that is connected to various digital contents and commerce is expected to increase in the future.

C. Domestic and Overseas Market Conditions

(1) Commerce markets

The Company expects that online/mobile commerce markets will continue to grow due to the growth potential of the Internet shopping population, the strengthening of online business models by off-line operators, and the rapid rise of mobile commerce. Recently, due to the widespread use of smartphones and social media, the commercialization of location-based services and the development of big data technology, online to offline (or, O2O) business, which is a concept of attracting customers to offline stores using online and mobile environments, is being highlighted as a new field in the online commerce market industry as new business models continue to emerge.

(2) Digital contents

The growth of application marketplaces, which started with Apples App Store, provides the platform business with new opportunities for revenue generation. The competitive paradigm is shifting from a competition among platform operators toward a competition among eco-systems that include application developers as well as platform operators.

D. Business Overview and Competitive Strengths

The Company plans to expand its platform ecosystem in operating its commerce business which includes marketplace and O2O businesses, such as 11st, Syrup and OK Cashbag, thereby ultimately increasing its enterprise value.

(1) Commerce business

11st, an online marketplace, has continued its growth through effective marketing and customer satisfaction. Despite its later entry into the online commerce market (launched in 2008) which was already divided between Auction and G-Market, it is leading the domestic e-commerce market. Furthermore, 11st has established itself as the domestic market leader in mobile commerce, following its successful entry into and rapid growth in this market. Growth plans involving overseas joint ventures based on 11sts business expertise have resulted in the successful launch of an open online commerce market in Turkey in partnership with Doğuş Group in March 2013. In October 2014, SK Planet and Celcom Axiata Berhad, which is a leading telecommunications service provider in Malaysia, established a joint venture, Celcom Planet, and launched online commerce services tailored to the Malaysian market in April 2015. 11st is not only actively engaged in operating such business in Malaysia, but has also launched its service in Thailand in February 2017.

Syrup is a consumer-oriented commerce service with the goal of minimizing its customers time and efforts while maximizing the economic benefits by providing information about coupons and events based on time, place and occasion. To achieve this goal, Syrup combines location-based services, such as geo-fencing, a virtual perimeter technology using a global positioning system (or, GPS) and Bluetooth Low Energy (or, BLE), with big data analysis of consumption patterns. Syrups business partners can benefit from cost-effective marketing through Syrup by utilizing statistics and analysis regarding consumers frequency of visits, preferred products, and consumption patterns.

OK Cashbag is a point-based loyalty marketing program which has grown to become a global top-tier loyalty marketing program since its inception in 1999. Customers have access to increased benefits through accumulation of loyalty reward points and partner companies use OK Cashbag as a marketing resource. As Koreas largest loyalty mileage program, OK Cashbag maintains a leading position in the industry. The Company is continuing to develop its service in light of market conditions and customers needs to enhance its customers perception of point value and is reviewing and pursuing various plans to develop OK Cashbag into a service that goes beyond a mileage program that leverages the key competitiveness of OK Cashbag such as its platform and partnership network.

(2) Location-based services

T-Map Navigation provides map, local information, real-time traffic information and navigation services. T-Map Navigation is one of the leading location-based service platforms in Korea. By entering the Online to Offline service area with T map Taxi, T map Public Transportation and others, the Company is expanding its mobile platform foundation that connects day to day life. In September 2016, the Company launched T-Map x NUGU, which provides a new form of intelligent car infortainment service in collaboration with the Companys artificial intelligence (AI) service, NUGU. The Company has continued to secure subscribers by differentiating its product T-map x NUGU as a unique artificial intelligence driving assistant. The Company has also focused on providing effective info-tainment platforms to commercial vehicle businesses as well as providing localized content, including region-specific information and advertisements. The Company plans to further develop the T-Map Navigation platform by initiating open application programming interface-based services, providing services to more diverse types of devices and providing local area-based services.

(3) Digital contents

Onestore, an application platform launched in 2016 through a joint venture between SK Telecom, KT, LG U+ and Navers app store, launched Onestore 2.0, which showcases the particular benefits of the application platform. The Company intends to further develop Onestore into a personalized gateway and mobile playground through enhanced product and brand competitiveness, expansion of the scope of serviceable devices, reinforcement of digital content offerings and enhancement of search services, among other things.

(4) Social networking services (SNS) and Internet portal services

(3) Policies for Allowance for Doubtful Accounts

The Company establishes allowances for doubtful accounts 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 two 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 customers service has been terminated or is continued). For such trade receivables that have been overdue for more than two years after the customers service has been terminated, the Company records an allowance of 100% of such receivables. For such trade receivables that have been overdue for less than two years after the customers service has been terminated or relates to a customer that is continuing his service, the Company records an allowance of a certain percentage of such receivable. 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.

Overview

In 2017, the Company built a solid foundation for its successful growth as Koreas representative new ICT company. Despite rapid changes in the domestic and overseas environment, the MNO business acheived both stability and growth, recording a turnaround revenue growth in three years and broadening its portfolio to new areas such as media, IoT, commerce and artificial intelligence.

In particular, the wireless telecommunications business recorded a 0.5% growth in revenue compared to the previous year, primarily through reinforcing its handset subscription base with systematic segment marketing and providing differentiated products and services that target the increasing data needs of customers and demand for other benefits. In addition, the Company maintained its annual churn rate at 1.4% through effective marketing that prioritizes retaining existing subscribers and avoiding unncessary competition over market share.

With respect to its digital network technology, the Company continues research and development activities with the aim of pioneering the worlds first commercialization of 5G technology, which is expected to become the fundamental basis of the fourth industrial revolution. The Company has been awarded multiple Global 5G Awards for its contribution to the global standardization of key technologies such as 5G fronthaul and network slicing. The Company successfully demonstrated the worlds first 5G communication technology toward the end of 2017 and has since been at the forefront of the global standardization process of 5G technology.

In addition to its wireless telecommunications business, the Company has continued growth in terms of its IPTV subscription volume and ARPU, while Oksusus market position has solidified as the number one mobile OTT (over-the-top) service in Korea. The Company expanded its IoT business and LoRa-based operations by entering into a comprehensive IoT cooperation agreement with the city of Seoul. The e-commerce business continued to remain profitable and recorded revenue growth driven by its mobile platform, while the Companys AI business broadened its platform and customer base and upgraded user value with the launch of T-map x NUGU.

In 2018, the ICT industry is expected to face new competition due to full-scale digitalization and accelerated convergence of other industries. The Company plans to utilize such growth opportunities with proactive development of key areas in new ICT such as AI and infrastructure, based on which it expects to innovate its wireless telecommunications business and achieve important breakthroughs in its media, IoT and platform service businesses.

The Companys operating revenue, on a consolidated basis, was Won 17,520.0 billion for the year ended December 31, 2017, a 2.5% increase from 2016 due to an increase in revenue from its wireless business and growth in its subsidiaries, among other reasons. The Companys operating income, on a consolidated basis, was Won 1,536.6 billion for the year ended December 31, 2017, a 0.1% increase from 2016 due to improved performance of its subsidiaries. For the year ended December 31, 2017, the Companys EBITDA (as further explained below) and profit for the year were Won 4,783.6 billion and Won 2,657.6 billion, respectively.

In 2017, the Companys capital expenditures, on a separate basis, were Won 1.98 trillion, which is consistent with the capital expenditure budget set at the beginning of the year. The Company expects to reduce and stabilize network capital expenditure, while expanding investment for the development of improved technologies in growth areas.

B. Average Monthly Revenue per Subscriber

Billing Average Monthly Revenue per Subscriber (Won)	35,209	35,355	146	(0.4	%)

The billing average monthly revenue per subscriber (ARPU) is derived by dividing total SK Telecom revenues from voice service and data service (but excluding revenue from MVNO subscribers) for the period by the monthly average number of subscribers that are not MVNO subscribers for the period, then dividing that number by the number of months in the period. Although the definition of ARPU may vary by company, it is a measure that is widely used in the telecommunications industry for revenue comparison purposes.

In 2017, despite the continued increase in average customer data usage, average revenue per subscriber decreased to Won 35,209, a 0.4% decrease compared to the previous year, primarily due to increases in the number of subscribers who elected to receive discounted rates in lieu of handset subsidies.

Guidance for Fiscal Year 2018

The Company announced the following guidance for fiscal year 2018 during its earnings release conference call on February 5, 2018.

Operating revenue (consolidated): Won 17.5 trillion

The Company expects operating revenue to be approximately Won 17.5 trillion in 2018. While there are factors that may lead to a decrease in revenue such as reduction in our rates, we expect revenue growth to continue in the new ICT area, including media and IoT businesses. On a separate basis, the Companys revenue is expected to decline compared to the previous year, primarily due to the decrease in wireless services revenue as a result of reduced rates, offset in part by growth in the IoT and data businesses. With respect to the Companys subsidiaries, SK Broadband is expected to continue revenue growth driven by the growth in IPTV, while SK Planet is expected to maintain a stable trajectory of growth driven by its 11st business, despite the existence of factors that may lead to a decrease in revenue such as the sale and streamlining of its non-core advertising business in October 2017.

SK Telecoms capital expenditures (separate): Won 2.1 trillion

The Company expects a slight increase in capital expenditures in 2018. It plans to reduce network capital expenditure while expanding investments for technology development in growth areas such as AI and IoT.

Cash dividends: The Company will decide on the level of cash dividends taking into consideration various factors such as the overall business environment and the Companys financial condition.
Corporate Reorganization

On December 7, 2017, SK Telecom undertook a corporate reorganization in order to innovate and grow as a leading new ICT company. SK Telecom organized its businesses into four business divisions: MNO, media, IoT/data and platform services, so that each business division can independently focus on growing its respective business and innovating and meeting its business goals. Within the MNO business division, SK Telecom established a new department in charge of joint sales and logistics of the four business divisions to create synergies for its B2B and B2C sales channels. A new AI research center was also established to increase its core technological competencies in AI and research and development of other growth areas. A new technology insight group that reports directly to the CEO has been established so SK Telecom can continue to pursue growth in new business areas. SK Telecoms main research center was renamed the ICT Research and Technology Center and it plans to increase the level of technological support to the core products of each of the four business divisions. In order to change its corporate image to be more innovative, SK Telecom established a new Creativity Center and plans for its renamed Open Collaboration Center to be more proactive in utilizing innovative ideas from start-ups and universities as well as creating social value.

Basis of Presentation, Continued

(3) 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.

(4) Use of estimates and judgments

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

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

1) Critical judgments

Information about critical judgments in applying accounting policies that have the most significant effect on the amounts recognized in the separate financial statements is included in Note 4 for classification of lease.

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: allowance for doubtful accounts, estimated useful lives of property and equipment and intangible assets, impairment of goodwill, recognition of provision, measurement of defined benefit liabilities, and recognition of deferred tax assets (liabilities).

3) Fair value measurement

A number of the Companys accounting policies and disclosures require the measurement of fair values, for both financial and non-financial assets and liabilities. The Company has an established policies and processes with respect to the measurement of fair values. This includes a valuation team that has overall responsibility for overseeing all significant fair value measurements, including Level 3 fair values, and reports directly to the finance executives.

The valuation team regularly reviews significant unobservable inputs and valuation adjustments. If third party information, such as broker quotes or pricing services, are used to measure fair values, then the valuation team 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:

Basis of Presentation, Continued

(4) Use of estimates and judgments, Continued

3) Fair value measurement, Continued

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 are included in Note 31.

Dividends from a subsidiary or associate are recognized in profit or loss when the right to receive the dividend is established.

The assets and liabilities acquired under business combination under common control are recognized at the carrying amounts in the ultimate controlling shareholders 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 financial asset 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 stated at the acquisition cost using the average method. During the period, a perpetual inventory system is used to track inventory quantities, which is adjusted to the physical inventory counts performed at the period end. When the net realizable value of inventories is less than the acquisition cost, the carrying amount is reduced to the net realizable value and any difference is charged to current operations as operating expenses.

(5) Non-derivative financial assets

The Company recognizes and measures non-derivative financial assets by the following four categories: financial assets at fair value through profit or loss, held-to-maturity investments, loans and receivables and available-for-sale financial assets. The Company recognizes financial assets in the separate statement of financial position when the Company becomes a party to the contractual provisions of the instrument.

Upon initial recognition, non-derivative financial assets not at fair value through profit or loss are measured at their fair value plus transaction costs that are directly attributable to the acquisition of asset.

(5) Non-derivative financial assets, Continued

(i) Financial assets at fair value through profit or loss

A financial asset is classified as financial asset at fair value through profit or loss if it is held for trading or is designated as such upon initial recognition. Upon initial recognition, transaction costs are recognized in profit or loss when incurred. Financial assets at fair value through profit or loss are measured at fair value, and changes therein are recognized in profit or loss.

(ii) Held-to-maturity investments

A non-derivative financial asset with a fixed or determinable payment and fixed maturity, for which the Company has the positive intention and ability to hold to maturity, are classified as held-to-maturity investment. Subsequent to initial recognition, held-to-maturity investments are measured at amortized cost using the effective interest rate method.

(iii) Loans and receivables

Loans and receivables are financial assets with fixed or determinable payments that are not quoted in an active market. Subsequent to initial recognition, loans and receivables are measured at amortized cost using the effective interest method except for loans and receivables of which the effect of discounting is immaterial.

(iv) Available-for-sale financial assets

Available-for-sale financial assets are those non-derivative financial assets that are designated as available-for-sale or are not classified as financial assets at fair value through profit or loss, held-to-maturity investments or loans and receivables. Subsequent to initial recognition, they are measured at fair value, with changes in fair value, net of any tax effect, recorded in other comprehensive income (OCI) in equity. Investments in equity instruments that do not have a quoted market price in an active market and whose fair value cannot be reliably measured are measured at cost.

(v) De-recognition of financial assets

The Company derecognizes a financial asset when the contractual rights to the cash flows from the asset expire, or it transfers the rights to receive the contractual cash flows on the financial asset in a transaction in which substantially all the risks and rewards of ownership of the financial asset are transferred. Any interest in transferred financial assets that is created or retained by the Company is recognized as a separate asset or liability. If the Company retains substantially all the risks and rewards of ownership of the transferred financial assets, the Company continues to recognize the transferred financial assets and recognizes financial liabilities for the consideration received.

(vi) Offsetting between financial assets and financial liabilities

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

(6) Derivative financial instruments, including hedge accounting

Derivatives are initially recognized at fair value. Subsequent to initial recognition, derivatives are measured at fair value, and changes therein are accounted for as described below.

(i) 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 risk of changes in the fair value of assets, liabilities or firm commitments (a fair value hedge) and foreign currency risk of highly probable forecasted transactions or firm commitments (a cash flow hedge).

On initial designation of the hedge, the 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.

Fair value hedge

Changes in the fair value of a derivative hedging instrument designated as a fair value hedge are recognized in profit or loss. The gain or loss from remeasuring the hedging instrument at fair value for a derivative hedging instrument and the gain or loss on the hedged item attributable to the hedged risk are recognized in profit or loss in the same line item of the statement of income. The Company discontinues fair value hedge accounting if the hedging instrument expires or is sold, terminated or exercised, or if the hedge no longer meets the criteria for hedge accounting. Any adjustment arising from gain or loss on the hedged item attributable to the hedged risk is amortized to profit or loss from the date the hedge accounting is discontinued.

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.

(ii) Separable embedded derivatives

Embedded derivatives are separated from the host contract and accounted for separately only if the following criteria have been met:

(a) the economic characteristics and risks of the embedded derivative are not closely related to those of the host contract;

(b) a separate instrument with the same terms as the embedded derivative would meet the definition of a derivative; and

(c) the hybrid (combined) instrument is not measured at fair value with changes in fair value recognized in profit or loss.

Changes in the fair value of separable embedded derivatives are recognized immediately in profit or loss.

(iii) Other derivative financial instruments

Changes in the fair value of other derivative financial instrument not designated as a hedging instrument are recognized immediately in profit or loss.

(7) Impairment of financial assets

A financial asset not carried at fair value through profit or loss is assessed at each reporting date to determine whether there is objective evidence that it is impaired. A financial asset is impaired if objective evidence indicates that a loss event has occurred after the initial recognition of the asset, and that the loss event had a negative effect on the estimated future cash flows of that asset that can be estimated reliably. However, losses expected as a result of future events, regardless of likelihood, are not recognized.

Objective evidence that a financial asset is impaired includes following loss events:

significant financial difficulty of the issuer or obligor;

a breach of contract, such as default or delinquency in interest or principal payments;

the lender, for economic or legal reasons relating to the borrowers financial difficulty, granting to the borrower a concession that the lender would not otherwise consider;

it becoming probable that the borrower will enter bankruptcy or other financial reorganization;

the disappearance of an active market for that financial asset because of financial difficulties; or

observable data indicating that there is a measurable decrease in the estimated future cash flows from a group of financial assets since the initial recognition of those assets, although the decrease cannot yet be identified with the individual financial assets in the group.

In addition, for an investment in an equity security, a significant or prolonged decline in its fair value below its cost is objective evidence of impairment.

If financial assets have objective evidence that they are impaired, impairment losses are measured and recognized.

(7) Impairment of financial assets, Continued

(i) Financial assets measured at amortized cost

An impairment loss in respect of a financial asset measured at amortized cost is calculated as the difference between its carrying amount and the present value of its estimated future cash flows discounted at the assets original effective interest rate. The Company can recognize impairment losses directly or by establishing an allowance account. If, in a subsequent period, the amount of the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized (such as an improvement in the debtors credit rating), the previously recognized impairment loss is reversed either directly or by adjusting an allowance account.

(ii) Financial assets carried at cost

If there is objective evidence that an impairment loss has occurred on an unquoted equity instrument that is not carried at fair value because its fair value cannot be reliably measured, or on a derivative asset that is linked to and must be settled by delivery of such an unquoted equity instrument, the amount of the impairment loss is measured as the difference between the carrying amount of the financial asset and the present value of estimated future cash flows discounted at the current market rate of return for a similar financial asset. Such impairment losses are not reversed.

(iii) Available-for-sale financial assets

When a decline in the fair value of an available-for-sale financial asset has been recognized in other comprehensive income and there is objective evidence that the asset is impaired, the cumulative loss that had been recognized in other comprehensive income is reclassified from equity to profit or loss as a reclassification adjustment even though the financial asset has not been derecognized. Impairment losses recognized in profit or loss for an investment in an equity instrument classified as available-for-sale is not reversed through profit or loss subsequently. If, in a subsequent period, the fair value of a debt instrument classified as available-for-sale increases and the increase can be objectively related to an event occurring after the impairment loss was recognized in profit or loss, the impairment loss is reversed, with the amount of the reversal recognized in profit or loss.

(8) 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.

Subsequent to initial recognition, an item of property and equipment is carried at its cost less any accumulated depreciation and any accumulated impairment losses.

(8) Property and equipment, Continued

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 measured reliably. 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 assets 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 Companys property and equipment are as follows:

	Useful lives (years)
Buildings and structures	15, 30
Machinery	3 ~ 6
Other property and equipment	4 ~ 10

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

(9) Borrowing costs

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

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

(10) Intangible assets

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

Amortization of intangible assets except for goodwill is calculated 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. This intangible asset is determined as having indefinite useful lives and not amortized.

The estimated useful lives of the Companys intangible assets are as follows:

	Useful lives (years)
Frequency usage rights	5 ~ 13
Land usage rights	5
Industrial rights	5, 10
Development costs	5
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 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 measured reliably, 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.

(11) Government grants

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

(i) Grants related to assets

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

(ii) Grants related to income

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

(12) Impairment of non-financial assets

The carrying amounts of the Companys non-financial assets, other than assets arising from 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 assets 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 amount to their carrying amount.

The Company estimates the recoverable amount of an individual asset, if it is impossible to measure the individual recoverable amount of an asset, then 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 synergies arising from the business acquired. Any impairment identified at the CGU level will first reduce the carrying value 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 assets carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortization, if no impairment loss had been recognized.

(13) Leases

The Company classifies and accounts for leases as either a finance or operating lease, depending on the terms. Leases where the Company assumes substantially all of the risks and rewards of ownership are classified as finance leases. All other leases are classified as operating leases.

(i) Finance leases

At the commencement of the lease term, the Company recognizes as finance assets and finance liabilities in its separate statement of financial position, the lower amount of the fair value of the leased property and the present value of the minimum lease payments, each determined at the inception of the lease. Any initial direct costs are added to the amount recognized as an asset.

Minimum lease payments are apportioned between the finance charge and the reduction of the outstanding liability. The finance charge is allocated to each period during the lease term so as to produce a constant periodic rate of interest on the remaining balance of the liability. Contingent rents are charged as expenses in the periods in which they are incurred.

The depreciable amount of a leased asset is allocated to each accounting period during the period of expected use on a systematic basis consistent with the depreciation policy the Company adopts for depreciable assets that are owned. If there is no reasonable certainty that the Company will obtain ownership by the end of the lease term, the asset is fully depreciated over the shorter of the lease term and its useful life. The Company reviews to determine whether the leased assets are impaired at the reporting date.

(ii) Operating leases

Leases where the lessor retains a significant portion of the risks and rewards of ownership are classified as operating leases. Payments made under operating leases (net of any incentives received from the lessor) are recognized in profit or loss on a straight-line basis over the period of the lease.

(iii) Determining whether an arrangement contains a lease

Determining whether an arrangement is, or contains, a lease is based on the substance of the arrangement and requires an assessment of whether fulfillment of the arrangement is dependent on the use of a specific asset and the arrangement conveys a right to use the asset.

At inception or reassessment of the arrangement, the Company separates payments and other consideration required by such an arrangement into those for the lease and those for other elements on the basis of their relative fair values. If the Company concludes for a financial lease that it is impracticable to separate the payments reliably, the Company recognizes an asset and a liability at an amount equal to the fair value of the underlying asset that was identified as the subject of the lease. Subsequently, the liability is reduced as payments are made and an imputed finance charge on the liability is recognized using the Companys incremental borrowing rate of interest.

(14) Non-current assets held for sale

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

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

(15) Non-derivative financial liabilities

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

(i) 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, financial liabilities at fair value through profit or loss are measured at fair value, and changes therein are recognized in profit or loss. Upon initial recognition, transaction costs that are directly attributable to the issue of the financial liability are recognized in profit or loss as incurred.

(ii) 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 liability. Subsequent to initial recognition, other financial liabilities are measured at amortized cost using the effective interest method.

The Company derecognizes a financial liability from the separate statement of financial position when it is extinguished (i.e. when the obligation specified in the contract is discharged, cancelled or expires).

(16) Employee benefits

(i) 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 the related service. When an employee has rendered 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.

(ii) 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 the related service. The Companys 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.

(iii) Retirement benefits: defined contribution plans

When an employee has rendered 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.

(iv) Retirement benefits: defined benefit plans

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

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

Remeasurements of the net defined benefit liability, 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 gain or loss on a settlement when the settlement of defined benefit plan occurs.

(v) Termination benefits

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

(17) Provisions

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

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

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

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

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

(18) 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 reporting dates exchange rate. 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.

Foreign currency differences arising on retranslation are recognized in profit or loss, except for differences arising on the retranslation of available-for-sale equity instruments.

(19) 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 profits or losses from the purchase, disposal, reissue, or retirement of treasury shares are directly recognized in equity being as transaction with owners.

(20) 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.

(21) 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 their value indirectly by reference to the fair value of the equity instruments granted. 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.

(22) Revenue

Revenue from the sale of goods, rendering of services or use of assets is measured at the fair value of the consideration received or receivable. Returns, trade discounts and volume rebates are recognized as a reduction of revenue.

When two or more revenue generating activities or deliverables are sold under a single arrangement, each deliverable that is considered to be a separate unit of account is accounted for separately. The allocation of consideration from a revenue arrangement to its separate units of account is based on the relative fair values of each unit.

(i) Services rendered

Revenue from cellular services consists of revenue from basic charges, voice charges, data charges, data-roaming services and interconnection charges. Such revenues are recognized as services are performed.

Revenue from other services rendered is recognized in profit or loss in proportion to the stage of completion of the transaction at the reporting date. The stage of completion is assessed by reference to surveys of work performed.

(ii) Goods sold

Revenue is recognized when persuasive evidence exists, usually in the form of an executed sales agreement, that the significant risks and rewards of ownership have been transferred to the buyer, recovery of the consideration is probable, the associated costs and possible return of goods can be estimated reliably, there is no continuing management involvement with the goods, and the amount of revenue can be measured reliably.

(iii) Customer loyalty programs

For customer loyalty programs, the fair value of the consideration received or receivable in respect of the initial sale is allocated between the award credits and the other components of the sale. The amount allocated to the award credits is estimated by reference to the fair value of the services to be provided with respect to the redeemable award credits. The fair value of the services to be provided with respect to the redeemable portion of the award credits granted to the customers in accordance with customer loyalty programs is estimated taking into account the expected redemption rate and timing of the expected redemption. Considerations allocated to the award credits are deferred and revenue is recognized when the award credits are recovered and the Company performs its obligation to provide the service. The amount of revenue recognized is based on the relative size of the total award credits that are expected to be redeemed and the redeemed award credits in exchange for services.

(23) Finance income and finance costs

Finance income comprises interest income on funds invested (including available-for-sale financial assets), dividend income, gains on disposal of available-for-sale financial assets, changes in fair value of financial assets at fair value through profit or loss, 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 on the date that the Companys right to receive payment is established.

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

(24) 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 other comprehensive income.

The Company prepares consolidated income tax returns under the tax-consolidation system and its economically unified wholly owned subsidiaries.

(i) Current tax

In accordance with the tax-consolidation system, the Company calculates current taxes on the consolidated taxable income for the Company and its wholly owned domestic subsidiaries 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.

(ii) Deferred tax

Deferred tax is recognized, 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.

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.

(ii) Deferred tax, Continued

Deferred tax assets and liabilities are offset only if there is a legally enforceable right to offset the related current tax liabilities and assets, and they relate to income taxes levied by the same tax authority and they are intended to be settled 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.

(25) 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.

(26) Standards issued but not yet effective

The following new standards are effective for annual periods beginning after January 1, 2017 and earlier application is permitted; however, the Company has not early adopted the following new standards in preparing the accompanying separate financial statements.

1) K-IFRS No. 1109, Financial Instruments

K-IFRS No. 1109, published on September 25, 2015 which will replace the K-IFRS No. 1039 Financial Instruments: Recognition and Measurement , is effective for annual periods beginning on or after January 1, 2018, with early adoption permitted. The Company currently plans to apply K-IFRS No.1109 in the period beginning on January 1, 2018.

K-IFRS No. 1109 will be applied retrospectively with exemption allowing the Company not to restate comparative information for prior periods with respect to classification and measurement changes. The Company will recognize any difference on the measurement of financial assets and liabilities in the opening balance of retained earnings of the year beginning January 1, 2018. In the case of hedge accounting, the prospective application is allowed except for those specified in K-IFRS No. 1109 such as accounting for the time value of options and the forward element of forward contracts which requires retrospective application.

Key features of K-IFRS No. 1109 includes new classification and measurement approach for financial assets that reflects the business model in which assets are managed and their cash flow characteristics, impairment model based on changes in expected credit losses, and new approach to hedge qualification and methods for assessing hedge effectiveness.

1) K-IFRS No. 1109, Financial Instruments , Continued

To ensure smooth implementation of K-IFRS No.1109, the Company needs to assess the financial impact of adopting K-IFRS No. 1109, to formulate the accounting policy, and to design, implement and enhance the accounting system and related controls. The expected quantitative impact of adopting K-IFRS No. 1109 on the Companys financial statements cannot be reliably estimated because it will be dependent on the financial instruments that the Company holds and economic conditions at that time as well as accounting elections and judgments that it will make in the future.

Based on the circumstances and information available as of December 31, 2017, the Company preliminary assessed the financial impact on its separate financial statements resulting from the adoption of K-IFRS No. 1109. The results of the preliminary assessment are as follows. The results are subject to change according to the additional information available in subsequent periods.

i) Classification and measurement of financial assets

Classification of financial assets under K-IFRS No. 1109 is driven by the entitys business model for managing financial assets and their contractual cash flows. This contains three principal classification categories: financial assets measured at amortized cost, fair value through other comprehensive income (FVOCI) and fair value through profit or loss (FVTPL). Derivatives embedded in contracts where the host is a financial asset are never bifurcated. Instead, the hybrid financial instrument as a whole is assessed for classification. Details of the classification based on business models and contractual cash flows are as follows;

| Business model assessment(1) | Contractual cash flow
characteristics | |
| --- | --- | --- |
| | Solely payments of principal and interest | Others |
| Hold to collect contractual cash flows | Amortized cost(2) | |
| Hold to collect contractual cash flows and sell financial assets | FVOCI- measured at fair value(2) | FVTPL-measured at fair value(3) |
| Hold to sell financial assets and others | FVTPL-measured at fair value | |

(*1) The business model will be assessed at portfolio level.

(*2) To eliminate or significantly reduce the accounting mismatch, the Company may irrevocably designate a financial asset as measured at FVTPL using the fair value option at initial recognition.

(*3) Equity instruments that are not held for trading may be irrevocably designated as FVOCI using the fair value option. This election will be made on an investment-by-investment basis.

As new classification requirements for financial assets under K-IFRS No. 1109 are more stringent than requirements under K-IFRS No. 1039, the adoption of the new standard may result in increase in financial assets designated as FVTPL and higher volatility in profit or loss of the Company. As of December 31, 2017, the Companys financial assets consist of W 4,019,888 million of loans and receivables, W 771,986 million of available-for-sale financial assets, and W 9,054 million of financial assets at fair value through profit or loss.

1) K-IFRS No. 1109, Financial Instruments, Continued

i) Classification and measurement of financial assets, Continued

A financial asset is measured at amortized cost under K-IFRS No. 1109 if the asset is held by the Company to collect its contractual cash flows and the assets contractual cash flows represent solely payments of principal and interest. As of December 31, 2017, the Company has W 4,019,888 million of loans and receivables measured at amortized cost.

Based on preliminary assessment, most of the Companys loans and receivables are held to collect their contractual cash flows and the assets contractual cash flows represent solely payments of principal and interest. Though some are held for collecting the assets contractual cash flows and sale, management does not expect this to have a significant impact due to the short term nature of the receivables.

A financial asset is measured at FVOCI under K-IFRS No. 1109 if the objective of the business model is achieved both by collecting contractual cash flows and selling financial assets; and the assets contractual cash flows represent solely payments of principal and interest. As of December 31, 2017, the Company has W 900 million of debt instruments classified as available-for-sale financial assets.

Most of the debt instruments held by the Company classified as available-for-sale financial assets are expected to be classified as financial assets measured at FVOCI upon adoption of K-IFRS No. 1109 as at January 1, 2018. Therefore, management does not expect there to be a significant impact.

Under K-IFRS No. 1109, equity instruments that are not held for trading may be irrevocably designated as FVOCI on initial recognition with no recycling of amounts from OCI to profit and loss. As of December 31, 2017, the Company has W 771,086 million of available-for-sale equity instruments.

As the Company plans to classify the equity instruments with long-term investment purposes to financial assets measured at FVOCI under K-IFRS No. 1109, the Companys preliminary assessment did not indicate any material impact on the Companys separate financial statements except no recycling of amounts from OCI to profit and loss is allowed.

All other financial assets are measured at FVTPL. As of December 31, 2017, the Company has no debt and equity instruments designated as FVTPL using the fair value option.

ii) Classification and measurement of financial liabilities

Under K-IFRS No. 1109, for the financial liabilities designated as FVTPL using the fair value option, the element of gains or losses attributable to changes in the own credit risk should normally be recognized in OCI, with the remainder recognized in profit or loss. These amounts recognized in OCI are not recycled to profit or loss even when the liability is derecognized. However, if presentation of the fair value change in respect of the liabilitys credit risk in OCI results in or enlarges an accounting mismatch in profit or loss, gains and losses are entirely presented in profit or loss.

As of December 31, 2017, the Companys total financial liability amounts to W 9,663,649 million, among which the financial liabilities designated as FVTPL using fair value option amount to W 60,278 million.

As of December 31, 2017, most of the financial liabilities designated as FVTPL of the Company have short-term maturities with no significant changes in their credit risks. The Companys preliminary assessment did not indicate any material impact on the Companys separate financial statements if K-IFRS No. 1109 were applied at December 31, 2017.

iii) Impairment: financial assets and contract assets

The current impairment requirements under K-IFRS No. 1039 are based on an incurred loss model, where the impairment exists if there is objective evidence as a result of one or more events that occurred after the initial recognition of an asset. However, K-IFRS No. 1109 replaces the incurred loss model in K-IFRS No. 1039 with an expected credit loss model which applies to debt instruments measured at amortized cost or at fair value through other comprehensive income.

Under K-IFRS No. 1109, the Company should recognize a loss allowance or provision at an amount equal to 12-month expected credit losses or lifetime expected credit losses for financial assets determined by the extent of probable credit deterioration since initial recognition as explained below. Therefore, the new impairment requirements are expected to result in earlier recognition of credit losses compared to the incurred loss model of K-IFRS No. 1039.

Stages (*1)		Loss allowances
Stage 1	No significant increase in credit risk since initial recognition (*2)	Loss allowances are determined for the amount of the expected credit losses that result from default events that are possible within 12 months after the reporting date.
Stage 2	Significant increase in credit risk since initial recognition	Loss allowances are determined for the amount of the expected credit losses that result from all possible default events over the expected life of the financial instrument.
Stage 3	Objective evidence of credit risk impairment

iii) Impairment: financial assets and contract assets, Continued

(*1) Under K-IFRS No. 1115, Revenue from Contracts with Customers (see note 4 (26) (2)), for trade receivables and contract assets arising with no significant credit risk, loss allowances are recognized at an amount equal to lifetime expected credit losses. However, for trade receivables and contract assets with a significant financing component arising under K-IFRS No. 1115, the Company may choose as its accounting policy to recognize loss allowances at an amount equal to lifetime expected credit losses. In addition, for receivables under lease arrangement, the Company may choose to recognize loss allowances at an amount equal to lifetime expected credit losses. The Company expects to perform the analysis on whether there was a significant increase in credit risk on collective basis instead of on individual instrument basis. In addition, when information that is more forward-looking than past due status is not available without undue cost or effort, the Company expects to use past due information to determine whether there have been significant increases in credit risk since initial recognition.

(*2) The Company may determine that a financial assets credit risk has not increased significantly if the asset has low credit risk at the reporting date.

K-IFRS No. 1109 allows the Company to only recognize the cumulative changes in lifetime expected credit losses since initial recognition as a loss allowance for purchased or originated credit-impaired financial assets at the reporting date. As of December 31, 2017, the Company has W 4,019,888 million of debt instrument financial assets measured at amortized cost and W 205,374 million as loss allowances for these assets. The Companys preliminary assessment did not indicate any material impact on the Companys separate financial statements upon adoption of K-IFRS No.1109 on January 1, 2018.

iv) Hedge accounting

K-IFRS No. 1109 maintains the mechanics of hedge accounting from those in K-IFRS No. 1039. However, K-IFRS No. 1109 replaces existing rule-based requirements under K-IFRS No. 1039 that are complex and difficult to apply with principle based requirement focusing more on the Companys risk management purposes and procedures. Under K-IFRS No. 1109, more hedging instruments and hedged items are permitted and 80%-125% effectiveness requirement is removed.

By complying with the hedging rules in K-IFRS No. 1109, the Company may apply hedge accounting for transactions that currently do not meet the hedging criteria under K-IFRS No. 1039 thereby reducing volatility in profit or loss. As of December 31, 2017, the Company recognized the total amount of W 1,548,247 million as hedged liabilities that applied hedge accounting and changes in fair value of cash flow hedge in the amount of W 70,572 million was recognized in OCI for the year ended December 31, 2017.

Upon initial application of K-IFRS No. 1109, the Company may choose as its accounting policy to continue to apply hedge accounting requirements under K-IFRS No. 1039 instead of the requirements in K-IFRS No. 1109.

iv) Hedge accounting, Continued

The Company is yet to decide on its accounting policy whether to continuously apply the hedge accounting requirements of K-IFRS No. 1039 instead of the requirements in K-IFRS No. 1109 when initially applying K-IFRS No. 1109. The Company designates derivatives such as currency swaps as hedging instruments to hedge the risk of variability in cash flows associated with the foreign currency debentures and borrowings. As the Companys hedging instruments as of December 31, 2017 satisfy the hedge requirements of retrospective testing (80~125%) under K-IFRS No. 1039, the adoption of K-IFRS No. 1109 is not expected to have material impact on the Companys separate financial statements.

2) K-IFRS No. 1115, Revenue from Contracts with Customers

K-IFRS No. 1115, Revenue from Contracts with Customers , published on November 6, 2015 is effective for annual periods beginning on or after January 1, 2018, with early adoption permitted. It replaces existing revenue recognition guidance, including K-IFRS No. 1018, Revenue , K-IFRS No. 1011, Construction Contracts , K-IFRS No. 2031, Revenue: Barter Transactions Involving Advertising Services , K-IFRS No. 2113, Customer Loyalty Programs , K-IFRS No. 2115, Agreements for the Construction of Real Estate , and K-IFRS No. 2118, Transfers of Assets from Customers . The Company plans to adopt K-IFRS No. 1115 on January 1, 2018. The Company plans to apply K-IFRS No. 1115 by recognizing the cumulative effect of initially applying K-IFRS No. 1115 as an adjustment to the opening balance of retained earnings (or other component of equity, as appropriate) of the year beginning January 1, 2018. The Company elected to apply K-IFRS No. 1115 retrospectively only to contracts that are not completed contracts at the date of initial application (January 1, 2018) using the transition method permitted by K-IFRS No. 1115.

K-IFRS No. 1018 provides separate revenue recognition criteria by transaction type which include sale of goods, rendering of services, and use of entity assets by others yielding interest, royalties and dividends. However, K-IFRS No. 1115 introduces a five-step model for revenue recognition that focuses on the transfer of control rather than the transfer of risks and rewards. The steps in five-step model are as follows:

identification of the contract with a customer;

identification of the performance obligations in the contract;

determination of the transaction price;

allocation of the transaction price to the performance obligations in the contract; and

recognition of revenue when (or as) the entity satisfies a performance obligation.

The Company updated its accounting system and related controls based on the understanding of the revenue stream of the Company with the assistance of external information technology and accounting specialists. The Company is assessing the financial impact of the adoption of K-IFRS No. 1115 on its separate financial statements and plans to complete the assessment by March 31, 2018. The results of the assessment will be disclosed in the Companys condensed separate interim financial statements for the three-month period ending March 31, 2018.

Based on the circumstances and information available as of December 31, 2017, the Company preliminary assessed the financial impact on its separate financial statements resulting from the adoption of K-IFRS No. 1115. The results of the preliminary assessment are as follows. The results are subject to change according to the additional information available to use in subsequent periods.

Incremental costs to acquire a contract

The Company has exclusive contracts with its sales agents to sell the Companys wireless telecommunications services to subscribers. These agents receive commissions depending on the number of subscribers newly added and retained. The commissions paid to the agents constitute a significant portion of the Companys operating expenses. Currently, the portion of these commissions that would not have been incurred if there have been no binding contracts with the subscribers are expensed.

Under K-IFRS No. 1115, for the Companys incremental costs to acquire a subscription contract, the Company expects to capitalize such amounts and amortized over the expected subscription period estimated based on historical experience. However, as a practical expedient, the Company plans to expense the incremental cost as incurred if the amortization period of the contract acquisition and fulfillment cost is considered to be not longer than one year.

As of December 31, 2017, the Company is assessing the impact of capitalizing the incremental costs associated with obtaining customer contracts. Based on the preliminary assessment, the Company expects commission expenses to decrease, while corresponding assets capitalized (incremental costs of obtaining a contract) and amortization expenses to be recognized and incurred, respectively.

3) K-IFRS No. 1116, Leases

K-IFRS No. 1116, published on May 22, 2017, is effective for annual periods beginning on or after January 1, 2019, with early adoption permitted. K-IFRS No. 1116 replaces existing leases guidance including K-IFRS No. 1017, Leases , K-IFRS No. 2104, Determining whether an Arrangement contains a Lease , K-IFRS No. 2015, Operating Leases Incentives, and K-IFRS No. 2027, Evaluating the Substance of Transactions Involving the Legal Form of a Lease .

K-IFRS No. 1116, at the inception date of a contract and the first implementation of the standard, requires the Company to determine whether a contract is, or contains, a lease unless the Company applies the practical expedient for the existing lease contract at the date of adoption of the standard.

When accounting for lease, lessee and lessor should account for each lease component within the contract as a lease separately from non-lease components of the contract.

Lessee recognizes a right-of-use asset representing its right to use the underlying asset and a lease liability representing its obligation to make lease payments. However, there are optional exemptions for short-term leases and leases of low value items. As a practical expedient, a lessee may elect, by class of underlying asset, not to separate non-lease components from lease components, and, instead, account for each lease component and any associated non-lease components as a single lease component.

3) K-IFRS No. 1116, Leases, Continued

Lessor accounting remains similar to the current standard K-IFRS No. 1017. For a sale and leaseback arrangement, K-IFRS No. 1116 requires the Company to apply the requirements for determining when a performance obligation is satisfied in K-IFRS No. 1115 to determine whether the transfer of an asset is accounted for as a sale of that asset. However, sale and leaseback arrangements entered into before the adoption of K-IFRS No. 1116 may not be reassessed.

(1) Lease accounting for lessees

As a lessee, the Company can either apply the K-IFRS No. 1116 using a full retrospective approach; or modified retrospective approach. The full retrospective approach requires the Company to retrospectively apply the new standard to each prior reporting period presented, while modified retrospective approach requires the lessee to recognize the cumulative effect of initial application at the date of initial application of the new leases standard.

(2) Lease accounting for lessors

In case where the Company is an intermediate lessor, the Company should reassess subleases that were classified as operating leases applying K-IFRS No. 1017 and are ongoing at the date of initial application, whether each sublease should be classified as an operating lease or a finance lease applying K-IFRS No. 1116. For subleases that were classified as operating leases applying K-IFRS No. 1017 but finance leases applying K-IFRS No. 1116, the Company should accounts for such sublease as a new finance lease entered into at the date of initial application of K-IFRS No. 1116.

The Company plans to update its accounting system and related controls and complete the assessment of impact on its separate financial statements resulting from the adoption of K-IFRS No. 1116 by December 31, 2018.

Financial assets at fair value through profit or loss			7,359
	W	4,051,354	3,909,429

Credit risk is the risk of financial loss to the Company if a customer or counterparty to a financial instrument fails to meet his/her contractual obligations.

To manage credit risk, the Company evaluates the credit worthiness of each customer or counterparty considering the partys 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 an allowance for doubtful account that represents its estimate of incurred losses in respect of trade and other receivables. 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 have been incurred but not yet identified. The collective loss allowance is determined based on historical data of payment statistics for similar financial assets. Also, the Companys credit risk can arise due to 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 amount of maximum exposure to credit risk of the Company is the carrying amount of financial assets as of December 31, 2017.

(3) Fair value, Continued

Fair value of the financial instruments that are traded in an active market (available-for-sale financial assets, financial liabilities at fair value through profit or loss, etc.) 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. Fair value of available-for-sale securities is determined using the market approach methods and financial assets through profit or loss are measured using the option pricing model. In addition, derivative financial contracts and long-term liabilities are measured using the discounted present value methods. Inputs used to such valuation methods include swap rate, interest rate, and risk premium, and the Company performs valuation using the inputs which are consistent with natures of assets and liabilities measured.

Interest rates used by the Company for the fair value measurement as of December 31, 2017 are as follows:

	Interest rate
Derivative instruments	1.54% ~ 2.24%
Borrowings and debentures	2.48% ~ 2.55%
Long-term payables other	2.23% ~ 2.60%

3) There have been no transfers from Level 2 to Level 1 in 2017 and changes of financial assets classified as Level 3 for the year ended December 31, 2017 are as follows:

Independent Accountants Review Report on Internal Accounting Control System

English translation of a Report Originally Issued in Korean

To the Representative Director of

SK Telecom Co., Ltd.

We have reviewed the accompanying Report on the Operations of Internal Accounting Control System (IACS) of SK Telecom Co., Ltd. (the Company) As of December 31, 2017. The Companys management is responsible for designing and maintaining effective IACS and for its assessment of the effectiveness of IACS. Our responsibility is to review managements assessment and issue a report based on our review. In the accompanying report of managements assessment of IACS, the Companys management stated: Based on the assessment on the operations of the IACS, the Companys IACS has been effectively designed and is operating as of December 31, 2017, in all material respects, in accordance with the IACS Framework issued by the Internal Accounting Control System Operation Committee.

We conducted our review in accordance with IACS Review Standards, issued by the Korean Institute of Certified Public Accountants. Those Standards require that we plan and perform the review to obtain assurance of a level less than that of an audit as to whether Report on the Operations of Internal Accounting Control System is free of material misstatement. Our review consists principally of obtaining an understanding of the Companys IACS, inquiries of company personnel about the details of the report, and tracing to related documents we considered necessary in the circumstances. We have not performed an audit and, accordingly, we do not express an audit opinion.

A companys IACS 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 generally accepted accounting principles. Because of its inherent limitations, however, IACS may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Based on our review, nothing has come to our attention that Report on the Operations of Internal Accounting Control System as of December 31, 2017 is not prepared, in all material respects, in accordance with IACS Framework issued by the Internal Accounting Control System Operation Committee.

This report applies to the Companys IACS in existence as of December 31, 2017. We did not review the Companys IACS subsequent to December 31, 2017. This report has been prepared for Korean regulatory purposes, pursuant to the External Audit Law, and may not be appropriate for other purposes or for other users.

Independent Auditors Report

Based on a report originally issued in Korean

To The Board of Directors and Shareholders

SK Telecom Co., Ltd.:

We have audited the accompanying consolidated financial statements of SK Telecom Co., Ltd. and its subsidiaries (the Group), which comprise the consolidated statements of financial position as at December 31, 2017 and 2016, the consolidated statements of income, comprehensive income, changes in equity and cash flows for the years then ended, and notes, comprising a summary of significant accounting policies and other explanatory information.

Managements Responsibility for the Consolidated Financial Statements

Management is responsible for the preparation and fair presentation of these consolidated financial statements in accordance with Korean International Financial Reporting Standards, 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.

Auditors Responsibility

Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with Korean Standards on Auditing. Those standards require that we comply with ethical requirements and plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the consolidated financial statements. The procedures selected depend on our judgment, including the assessment of the risks of material misstatement of the consolidated financial statements, whether due to fraud or error. In making those risk assessments, we consider internal control relevant to the entitys preparation and fair presentation of the consolidated financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entitys internal control. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of accounting estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Group as at December 31, 2017 and 2016 and of its consolidated financial performance and its consolidated cash flows for the years then ended in accordance with Korean International Financial Reporting Standards.

(3) 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 Companys functional and presentation currency.

(4) Use of estimates and judgments

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

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

1) Critical judgments

Information about critical judgments in applying accounting policies that have the most significant effect on the amounts recognized in the consolidated financial statements is included in Note 4 for the following areas: consolidation: whether the Group has de facto control over an investee, and classification of lease.

2) Assumptions and estimation uncertainties

3) Fair value measurement

A number of the Groups 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. This includes a valuation team that has overall responsibility for overseeing all significant fair value measurements, including Level 3 fair values, and reports directly to the finance executives.

The valuation team 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 valuation team 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.

3) Fair value measurement, Continued

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).

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 34.

Changes in accounting policies

1) K-IFRS No. 1007, Cash Flow Statements

The Group adopted the amendments to K-IFRS No. 1007, which form a part of the IASBs broader disclosure in the period beginning on January 1, 2017. The amendment requires the Group to provide disclosures that enable users of financial statements to evaluate changes in liabilities arising from financing activities, including both changes arising from cash flows and non-cash changes. The Group disclosed the reconciliation of the opening and closing balances of liabilities arising from financing activities including changes from financing cash flows; changes arising from obtaining or losing control of subsidiaries or other businesses; the effect of changes in foreign exchange rates; changes in fair values; and other changes in Note 37.

2) K-IFRS No. 1012, Income Taxes

The Group adopted the amendments to K-IFRS No. 1012 in the period beginning January 1, 2017. The amendments clarify the necessity to consider whether there are restrictions on tax laws on the sources of taxable profits which may be used for the reversal of deductible temporary difference. In addition, the amendments provide the guidance on how to estimate the probable future taxable profit and specify the circumstances where an asset can be recovered for more than its carrying amount. These amendments have no impact on the Groups consolidated financial statements.

Significant Accounting Policies

The significant accounting policies applied by the Group in the preparation of its consolidated financial statements in accordance with K-IFRSs are included below. The accounting policies set out below have been applied consistently to all periods presented in these consolidated financial statements.

(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 Groups other components. The Groups 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 four reportable segments which consist of cellular services, fixed-line telecommunication services, e-commerce services and others, as described in Note 5. 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

(i) 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.

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 companys 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 excluding costs to issue debt or equity securities recognized based on K-IFRS No. 1032 and 1039.

Consideration transferred does not include the amount settled in relation to the pre-existing relationship and the amount settled in relation to the pre-existing relationship is 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) Basis of consolidation, Continued

(ii) Non-controlling interests

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

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

(iii) 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.

(iv) 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.

(v) 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 entitys 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 Groups share of the profit or loss and changes in equity of the associate or the joint venture after the date of acquisition.

(vi) 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 Groups 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.

(vii) Business combinations under common control

SK Holdings Co., Ltd. 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 shareholders 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

(4) Inventories

(5) Non-derivative financial assets

The Group recognizes and measures non-derivative financial assets by the following four categories: financial assets at fair value through profit or loss, held-to-maturity investments, loans and receivables and available-for-sale financial assets. The Group recognizes financial assets in the consolidated statement of financial position when the Group becomes a party to the contractual provisions of the instrument.

(i) Financial assets at fair value through profit or loss

(ii) Held-to-maturity investments

A non-derivative financial asset with a fixed or determinable payment and fixed maturity, for which the Group has the positive intention and ability to hold to maturity, are classified as held-to-maturity investment. Subsequent to initial recognition, held-to-maturity investments are measured at amortized cost using the effective interest rate method.

(iii) Loans and receivables

(iv) Available-for-sale financial assets

Available-for-sale financial assets are those non-derivative financial assets that are designated as available-for-sale or are not classified as financial assets at fair value through profit or loss, held-to-maturity investments or loans and receivables. Subsequent to initial recognition, they are measured at fair value with changes in fair value, net of any tax effect, recorded in other comprehensive income (OCI) in equity. Investments in equity instruments that do not have a quoted market price in an active market and whose fair value cannot be reliably measured are measured at cost.

(v) De-recognition of financial assets

The Group derecognizes a financial asset when the contractual rights to the cash flows from the asset expire, or it transfers the rights to receive the contractual cash flows on the financial asset in a transaction in which substantially all the risks and rewards of ownership of the financial asset are transferred. Any interest in transferred financial assets that is created or retained by the Group is recognized as a separate asset or liability. If the Group retains substantially all the risks and rewards of ownership of the transferred financial assets, the Group continues to recognize the transferred financial assets and recognizes financial liabilities for the consideration received.

(vi) Offsetting between financial assets and financial liabilities

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

(6) Derivative financial instruments, including hedge accounting

Derivatives are initially recognized at fair value. Subsequent to initial recognition, derivatives are measured at fair value, and changes therein are accounted for as described below.

(i) 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 risk of changes in the fair value of assets, liabilities or firm commitments (a fair value hedge) and foreign currency risk of highly probable forecasted transactions or firm commitments (a cash flow hedge).

On initial designation of the hedge, the Group 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.

(i) Hedge accounting, Continued

Fair value hedge

Changes in the fair value of a derivative hedging instrument designated as a fair value hedge are recognized in profit or loss. The gain or loss from remeasuring the hedging instrument at fair value for a derivative hedging instrument and the gain or loss on the hedged item attributable to the hedged risk are recognized in profit or loss in the same line item of the consolidated statement of income. The Group discontinues fair value hedge accounting if the hedging instrument expires or is sold, terminated or exercised, or if the hedge no longer meets the criteria for hedge accounting. Any adjustment arising from gain or loss on the hedged item attributable to the hedged risk is amortized to profit or loss from the date the hedge accounting is discontinued.

Cash flow hedge

(ii) Separable embedded derivatives

Embedded derivatives are separated from the host contract and accounted for separately only if the following criteria have been met:

(a) the economic characteristics and risks of the embedded derivative are not closely related to those of the host contract;

(b) a separate instrument with the same terms as the embedded derivative would meet the definition of a derivative; and

(c) the hybrid (combined) instrument is not measured at fair value with changes in fair value recognized in profit or loss.

Changes in the fair value of separable embedded derivatives are recognized immediately in profit or loss.

(iii) Other derivative financial instruments

Changes in the fair value of other derivative financial instrument not designated as a hedging instrument are recognized immediately in profit or loss.

(7) Impairment of financial assets

Objective evidence that a financial asset is impaired includes following loss events:

significant financial difficulty of the issuer or obligor;

a breach of contract, such as default or delinquency in interest or principal payments;

the lender, for economic or legal reasons relating to the borrowers financial difficulty, granting to the borrower a concession that the lender would not otherwise consider;

it becoming probable that the borrower will enter bankruptcy or other financial reorganization;

the disappearance of an active market for that financial asset because of financial difficulties; or

In addition, for an investment in an equity security, a significant or prolonged decline in its fair value below its cost is objective evidence of impairment.

If financial assets have objective evidence that they are impaired, impairment losses are measured and recognized.

(i) Financial assets measured at amortized cost

An impairment loss in respect of a financial asset measured at amortized cost is calculated as the difference between its carrying amount and the present value of its estimated future cash flows discounted at the assets original effective interest rate. The Group can recognize impairment losses directly or by establishing an allowance account. If, in a subsequent period, the amount of the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized (such as an improvement in the debtors credit rating), the previously recognized impairment loss is reversed either directly or by adjusting an allowance account.

(ii) Financial assets carried at cost

(8) Property and equipment

Subsequent to initial recognition, an item of property and equipment is carried at its cost less any accumulated depreciation and any 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 measured reliably. 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.

The estimated useful lives of the Groups property and equipment are as follows:

	Useful lives (years)
Buildings and structures	15 ~ 40
Machinery	3 ~ 15
Other property and equipment	2 ~ 10

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

(9) Borrowing costs

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

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

(10) Intangible assets

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

The estimated useful lives of the Groups intangible assets are as follows:

	Useful lives (years)
Frequency usage rights	5 ~ 13
Land usage rights	5
Industrial rights	5, 10
Development costs	3 ~ 5
Facility usage rights	10, 20
Customer relations	3 ~ 7
Other	3 ~ 20

(10) 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 measured reliably, 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.

(11) Government grants

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

(i) Grants related to assets

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

(ii) Grants related to income

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

(12) Investment property

Property held for the purpose of earning rentals or benefiting from capital appreciation is classified as investment property. Investment property is initially measured at its cost. Transaction costs are included in the initial measurement. Subsequently, investment property is carried at depreciated cost less any accumulated impairment losses.

Subsequent costs are recognized in the carrying amount of investment property 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 measured reliably. 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.

Investment property except for land, are depreciated on a straight-line basis over 15~40 years as estimated useful lives.

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

(13) Impairment of non-financial assets

The carrying amounts of the Groups non-financial assets, other than assets arising from 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 assets 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 amount to their carrying amount.

The Group estimates the recoverable amount of an individual asset, if it is impossible to measure the individual recoverable amount of an asset, then 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.

(14) Leases

The Group classifies and accounts for leases as either a finance or operating lease, depending on the terms. Leases where the Group assumes substantially all of the risks and rewards of ownership are classified as finance leases. All other leases are classified as operating leases.

(i) Finance leases

At the commencement of the lease term, the Group recognizes as finance assets and finance liabilities in its consolidated statement of financial position, the lower amount of the fair value of the leased property and the present value of the minimum lease payments, each determined at the inception of the lease. Any initial direct costs are added to the amount recognized as an asset.

(14) Leases, Continued

(i) Finance leases, Continued

The depreciable amount of a leased asset is allocated to each accounting period during the period of expected use on a systematic basis consistent with the depreciation policy the Group adopts for depreciable assets that are owned. If there is no reasonable certainty that the Group will obtain ownership by the end of the lease term, the asset is fully depreciated over the shorter of the lease term and its useful life. The Group reviews to determine whether the leased assets are impaired at the reporting date.

(ii) Operating leases

(iii) Determining whether an arrangement contains a lease

At inception or reassessment of the arrangement, the Group separates payments and other consideration required by such an arrangement into those for the lease and those for other elements on the basis of their relative fair values. If the Group concludes for a financial lease that it is impracticable to separate the payments reliably, the Group recognizes an asset and a liability at an amount equal to the fair value of the underlying asset that was identified as the subject of the lease. Subsequently, the liability is reduced as payments are made and an imputed finance charge on the liability is recognized using the Groups incremental borrowing rate of interest.

(15) Non-current assets held for sale

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

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

(16) 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 liability.

(i) Financial liabilities at fair value through profit or loss

(ii) Other financial liabilities

The Group derecognizes a financial liability from the consolidated statement of financial position when it is extinguished (i.e. when the obligation specified in the contract is discharged, cancelled or expires).

(17) Employee benefits

(i) 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 the related service. When an employee has rendered 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.

(ii) 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 the related service. The Groups 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.

(iii) Retirement benefits: defined contribution plans

When an employee has rendered 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.

(iv) Retirement benefits: defined benefit plans

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

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

Remeasurements of the net defined benefit liability, 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 gain or loss on a settlement when the settlement of defined benefit plan occurs.

(v) Termination benefits

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

(18) 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.

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

(19) Transactions in foreign currencies

(i) Foreign currency transactions

Transactions in foreign currencies are translated to the functional currency of 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 reporting dates exchange rate. 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.

Foreign currency differences arising on retranslation are recognized in profit or loss, except for differences arising on the retranslation of available-for-sale equity instruments.

(ii) Foreign operations

If the presentation currency of the Group is different from a foreign operations 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.

(19) Transactions in foreign currencies, Continued

(ii) Foreign operations, Continued

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

(20) Share capital

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

(21) Hybrid bond

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

(22) Share-based Payment

For equity-settled share-based payment transaction, if the fair value of the goods or services received cannot be reliably estimated, the Group measures their value indirectly by reference to the fair value of the equity instruments granted. 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.

(23) Revenue

Revenue from the sale of goods, rendering of services or use of the Group assets is measured at the fair value of the consideration received or receivable. Returns, trade discounts and volume rebates are recognized as a reduction of revenue.

(i) Services rendered

Revenue from fixed-line services includes domestic and long-distance call charges, international phone connection charges, and broadband internet services. Such revenues are recognized as the related services are performed.

(ii) Goods sold

(iii) Commission revenue

In connection with the commission revenue from e-commerce services, the Group has determined that it is acting as an agent due to the followings:

The Group does not bear inventory risk or have responsibility for the delivery goods;

All of the credit risks are borne by suppliers of goods though the Group collects the proceeds from end customers on behalf of the suppliers; and

The Group has no latitude in establishing prices regarding goods sold in e-commerce.

(iv) Customer loyalty programs

For customer loyalty programs, the fair value of the consideration received or receivable in respect of the initial sale is allocated between the award credits and the other components of the sale. The amount allocated to the award credits is estimated by reference to the fair value of the services to be provided with respect to the redeemable award credits. The fair value of the services to be provided with respect to the redeemable portion of the award credits granted to the customers in accordance with customer loyalty programs is estimated taking into account the expected redemption rate and timing of the expected redemption. Considerations allocated to the award credits are deferred and revenue is recognized when the award credits are recovered and the Group performs its obligation to provide the service. The amount of revenue recognized is based on the relative size of the total award credits that are expected to be redeemed and the redeemed award credits in exchange for services.

(24) Finance income and finance costs

(25) Income taxes

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

(i) Current tax

In accordance with the tax-consolidation system, the Parent Company calculates current taxes for the Parent Company and its wholly owned domestic subsidiaries and recognizes the income tax payable as current tax liabilities of the Parent 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.

(ii) Deferred tax

Deferred tax is recognized, 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.

(ii) Deferred tax, Continued

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.

(26) Earnings per share

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

(27) Standards issued but not yet effective

The following new standards are effective for annual periods beginning after January 1, 2017 and earlier application is permitted; however, the Group has not early adopted the following new standards in preparing the accompanying consolidate financial statements.

1) K-IFRS No. 1109, Financial Instruments

K-IFRS No. 1109, published on September 25, 2015 which will replace the K-IFRS No. 1039 Financial Instruments: Recognition and Measurement , is effective for annual periods beginning on or after January 1, 2018, with early adoption permitted. The Group currently plans to apply K-IFRS No.1109 in the period beginning on January 1, 2018.

K-IFRS No. 1109 will be applied retrospectively with exemption allowing the Group not to restate comparative information for prior periods with respect to classification and measurement changes. The Group will recognize any difference on the measurement of financial assets and liabilities in the opening balance of retained earnings of the year beginning January 1, 2018. In the case of hedge accounting, the prospective application is allowed except for those specified in K-IFRS No. 1109 such as accounting for the time value of options and the forward element of forward contracts which requires retrospective application.

To ensure smooth implementation of K-IFRS No.1109, the Group needs to assess the financial impact of adopting K-IFRS No. 1109, to formulate the accounting policy, and to design, implement and enhance the accounting system and related controls. The expected quantitative impact of adopting K-IFRS No. 1109 on the Groups financial statements cannot be reliably estimated because it will be dependent on the financial instruments that the Group holds and economic conditions at that time as well as accounting elections and judgments that it will make in the future.

Based on the circumstances and information available as of December 31 2017, the Group preliminary assessed the financial impact on its consolidated financial statements resulting from the adoption of K-IFRS No. 1109. The results of the preliminary assessment are as follows. The results are subject to change according to the additional information available in subsequent periods.

| --- | --- | --- |
| | Solely payments of principal and
interest | Others |
| Hold to collect contractual cash flows | Amortized cost(2) | FVTPL-measured at fair value (3) |
| Hold to collect contractual cash flows and sell financial assets | FVOCI- measured at fair value (2) | |
| Hold to sell financial assets and others | FVTPL-measured at fair value | |

(*1) The business model will be assessed at portfolio level.

(*2) To eliminate or significantly reduce the accounting mismatch, the Group may irrevocably designate a financial asset as measured at FVTPL using the fair value option at initial recognition.

(*3) Equity instruments that are not held for trading may be irrevocably designated as FVOCI using the fair value option. This election will be made on an investment-by-investment basis.

As new classification requirements for financial assets under K-IFRS No. 1109 are more stringent than requirements under K-IFRS No. 1039, the adoption of the new standard may result in increase in financial assets designated as FVTPL and higher volatility in profit or loss of the Group. As of December 31, 2017, the Groups financial assets consist of W 6,176,575 million of loans and receivables, W 934,390 million of available-for-sale financial assets, and W 328,314 million of financial assets at fair value through profit or loss.

A financial asset is measured at amortized cost under K-IFRS No. 1109 if the asset is held by the Group to collect its contractual cash flows and the assets contractual cash flows represent solely payments of principal and interest. As of December 31, 2017, the Group has W 6,176,575 million of loans and receivables measured at amortized cost.

Based on preliminary assessment, most of the Groups loans and receivables are held to collect their contractual cash flows and the assets contractual cash flows represent solely payments of principal and interest. Though some are held for collecting the assets contractual cash flows and sale, management does not expect this to have a significant impact due to the short term nature of the receivables.

A financial asset is measured at FVOCI under K-IFRS No. 1109 if the objective of the business model is achieved both by collecting contractual cash flows and selling financial assets; and the assets contractual cash flows represent solely payments of principal and interest. As of December 31, 2017, the Group has W 19,928 million of debt instruments classified as available-for-sale financial assets.

i) Classification and measurement of financial assets, Continued

Most of the debt instruments held by the Group classified as available-for-sale financial assets are expected to be classified as financial assets measured at FVOCI upon adoption K-IFRS No. 1109 as at January 1, 2018. Therefore, management does not expect there to be a significant impact.

Under K-IFRS No. 1109, equity instruments that are not held for trading may be irrevocably designated as FVOCI on initial recognition with no recycling of amounts from OCI to profit and loss. As of December 31, 2017, the Group has W 914,462 million of available-for-sale equity instruments.

As the Group plans to classify the equity instruments with long-term investment purposes to financial assets measured at FVOCI under K-IFRS No. 1109, the Groups preliminary assessment did not indicate any material impact on the Groups consolidated financial statements except no recycling of amounts from OCI to profit and loss is allowed.

All other financial assets are measured at FVTPL. As of December 31, 2017, the Group has W 97,003 million of debt instruments classified as financial assets at FVTPL.

Most of the financial assets classified as FVTPL under K-IFRS No. 1039 of the Group are expected to be designated as financial assets measured at FVTPL under K-IFRS No. 1109. Therefore, the Groups preliminary assessment did not indicate any material impact on the Groups consolidated financial statements upon adoption of K-IFRS No. 1109 as at January 1, 2018.

ii) Classification and measurement of financial liabilities

As of December 31, 2017, the Groups total financial liability amounts to W 12,725,704 million, among which the financial liabilities designated as FVTPL using fair value option amount to W 60,278 million.

As of December 31, 2017, most of the financial liabilities designated as FVTPL of the Group have short-term maturities with no significant changes in their credit risks. The Groups preliminary assessment did not indicate any material impact on the Groups consolidated financial statements if K-IFRS No. 1109 were applied at December 31, 2017.

iii) Impairment: financial assets and contract assets

Under K-IFRS No. 1109, the Group should recognize a loss allowance or provision at an amount equal to 12-month expected credit losses or lifetime expected credit losses for financial assets determined by the extent of probable credit deterioration since initial recognition as explained below. Therefore, the new impairment requirements are expected to result in earlier recognition of credit losses compared to the incurred loss model of K-IFRS No. 1039.

Stages (*1)		Loss allowances
Stage 1	No significant increase in credit risk since initial recognition (*2)	Loss allowances are determined for the amount of the expected credit losses that result from default events that are possible within 12 months after the reporting date.
Stage 2	Significant increase in credit risk since initial recognition	Loss allowances are determined for the amount of the expected credit losses that result from all possible default events over the expected life of the financial instrument.
Stage 3	Objective evidence of credit risk impairment

(*1) Under K-IFRS No. 1115, Revenue from Contracts with Customers (see note 4 (27) (2)), for trade receivables and contract assets arising with no significant credit risk, loss allowances are recognized at an amount equal to lifetime expected credit losses. However, for trade receivables and contract assets with a significant financing component arising under K-IFRS No. 1115, the Group may choose as its accounting policy to recognize loss allowances at an amount equal to lifetime expected credit losses. In addition, for receivables under lease arrangement, the Group may choose to recognize loss allowances at an amount equal to lifetime expected credit losses. The Group expects to perform the analysis on whether there was a significant increase in credit risk on collective basis instead of on individual instrument basis. In addition, when information that is more forward-looking than past due status is not available without undue cost or effort, the Group expects to use past due information to determine whether there have been significant increases in credit risk since initial recognition.

(*2) The Group may determine that a financial assets credit risk has not increased significantly if the asset has low credit risk at the reporting date.

iii) Impairment: financial assets and contract assets, Continued

K-IFRS No. 1109 allows the Group to only recognize the cumulative changes in lifetime expected credit losses since initial recognition as a loss allowance for purchased or originated credit-impaired financial assets at the reporting date. As of December 31, 2017, the Group has W 6,176,575 million of debt instrument financial assets measured at amortized cost and W 362,171 million as loss allowances for these assets. The Groups preliminary assessment did not indicate any material impact on the Groups consolidated financial statements upon adoption of K-IFRS No. 1109 on January 1, 2018.

iv) Hedge accounting

K-IFRS No. 1109 maintains the mechanics of hedge accounting from those in K-IFRS No. 1039. However, K-IFRS No. 1109 replaces existing rule-based requirements under K-IFRS No. 1039 that are complex and difficult to apply with principle based requirement focusing more on the Groups risk management purposes and procedures. Under K-IFRS No. 1109, more hedging instruments and hedged items are permitted and 80%-125% effectiveness requirement is removed.

By complying with the hedging rules in K-IFRS No. 1109, the Group may apply hedge accounting for transactions that currently do not meet the hedging criteria under K-IFRS No. 1039 thereby reducing volatility in profit or loss. As of December 31, 2016, the Group recognized the total amount of W 2,026,434 million as hedged liabilities that applied hedge accounting and changes in fair value of cash flow hedge in the amount of W 73,828 million was recognized in OCI for the year ended December 31, 2017.

Upon initial application of K-IFRS No. 1109, the Group may choose as its accounting policy to continue to apply hedge accounting requirements under K-IFRS No. 1039 instead of the requirements in K-IFRS No. 1109.

The Group is yet to decide on its accounting policy whether to continuously apply the hedge accounting requirements of K-IFRS No. 1039 instead of the requirements in K-IFRS No. 1109 when initially applying K-IFRS No. 1109. The Group designates derivatives such as currency swaps as hedging instruments to hedge the risk of variability in cash flows associated with the foreign currency debentures and borrowings. As the Groups hedging instruments as of December 31, 2017 satisfy the hedge requirements of retrospective testing (80~125%) under K-IFRS No. 1039, the adoption of K-IFRS No. 1109 is not expected to have material impact on the Groups consolidated financial statements.

2) K-IFRS No. 1115, Revenue from Contracts with Customers

K-IFRS No. 1115, Revenue from Contracts with Customers , published on November 6, 2015 is effective for annual periods beginning on or after January 1, 2018, with early adoption permitted. It replaces existing revenue recognition guidance, including K-IFRS No. 1018, Revenue , K-IFRS No. 1011, Construction Contracts , K-IFRS No. 2031, Revenue: Barter Transactions Involving Advertising Services , K-IFRS No. 2113, Customer Loyalty Programs , K-IFRS No. 2115, Agreements for the Construction of Real Estate , and K-IFRS No. 2118, Transfers of Assets from Customers . The Group plans to adopt K-IFRS No. 1115 on January 1, 2018. The Group plans to apply K-IFRS No. 1115 by recognizing the cumulative effect of initially applying the K-IFRS No. 1115 as an adjustment to the opening balance of retained earnings (or other component of equity, as appropriate) of the year beginning January 1, 2018. The Group elected to apply K-IFRS No. 1115 retrospectively only to contracts that are not completed contracts at the date of initial application (January 1, 2018) using the transition method permitted by K-IFRS No. 1115.

identification of the contract with a customer;

identification of the performance obligations in the contract;

determination of the transaction price;

allocation of the transaction price to the performance obligations in the contract; and

recognition of revenue when (or as) the entity satisfies a performance obligation.

The Group updated its accounting system and related controls based on the understanding of the revenue stream of the Group with the assistance of external information technology and accounting specialists. The Group is assessing the financial impact of the adoption of K-IFRS No. 1115 on its consolidated financial statements and plans to complete the assessment by March 31, 2018. The results of the assessment will be disclosed in the Groups condensed consolidated interim financial statements for the three-month period ending March 31, 2018.

Based on the circumstances and information available as of December 31, 2017, the Group preliminarily assessed the financial impact on its consolidated financial statements resulting from the adoption of K-IFRS No. 1115. The results of the preliminary assessment are as follows. The results are subject to change according to the additional information available to use in subsequent periods.

i) Identification of performance obligations in the contract

A substantial portion of the Groups revenues are generated from provision of wireless telecommunications services. K-IFRS No. 1115 requires the Group to evaluate goods or services promised to customers to determine if they are performance obligations other than wireless telecommunications service that should be accounted for separately. The amount and timing of revenue recognition under K-IFRS No. 1105 may be different from those under K-IFRS No. 1018 depending on the conclusion over the existence of separately identifiable performance obligations and the timing of satisfying each performance obligation.

2) K-IFRS No. 1115, Revenue from Contracts with Customers, Continued

i) Identification of performance obligations in the contract, Continued

In the case that the Group provides the wireless telecommunications services and a handset to one customer, the Group will allocate considerations from the customer between handset sale revenue and wireless telecommunications service revenue. The handset sales revenue is recognized when handset is sold and the wireless telecommunications service revenue is recognized as revenue over the period of the contract term as stated in the subscription contract.

ii) Allocate the transaction price to the separate performance obligations

In accordance with K-IFRS No. 1115, the Group should allocate the transaction price to each performance obligation in a contract in proportion to their stand-alone selling price. The Group plans to use adjusted market assessment method for estimating the stand-alone selling price. However, in some circumstances, expected cost plus a margin approach will be used.

The Group is in the progress of assessing the financial impact of allocating the transaction price to each performance obligation in a contract in proportion to their stand-alone selling price for the case where the Group provides the wireless telecommunications services and handset to one customer. Based on the preliminary assessment, the Group expects that wireless telecommunications service revenue will be decreased, while handset sale revenue will be increased upon adoption of K-IFRS No. 1115.

iii) Incremental costs to acquire a contract

The Group has exclusive contracts with its sales agents to sell the Groups wireless telecommunications services to subscribers. These agents receive commissions depending on the number of subscribers newly added and retained. The commissions paid to the agents constitute a significant portion of the Groups operating expenses. Currently, the portion of these commissions that would not have been incurred if there have been no binding contracts with the subscribers are expensed.

Under K-IFRS No. 1115, for the Groups incremental costs to acquire a subscription contract, the Group expects to capitalize such amounts and amortized over the expected subscription period estimated based on historical experience. However, as a practical expedient, the Group plans to expense the incremental cost as incurred if the amortization period of the contract acquisition and fulfillment cost is considered to be not longer than one year.

As of December 31, 2017, the Group is assessing the impact of capitalizing the incremental costs associated with obtaining customer contracts. Based on the preliminary assessment, the Group expects commission expenses to decrease, while corresponding assets capitalized (incremental costs of obtaining a contract) and amortization expenses to be recognized and incurred, respectively.

Significant Accounting Policies, Continued

(27) Standards issued but not yet effective, Continued

3) K-IFRS No. 1116, Leases

K-IFRS No. 1116, published on May 22, 2017 is effective for annual periods beginning on or after January 1, 2019, with early adoption permitted. K-IFRS No. 1116 replaces existing leases guidance including K-IFRS No. 1017, Leases , K-IFRS No. 2104, Determining whether an Arrangement contains a Lease , K-IFRS No.2015, Operating Leases Incentives and K-IFRS No. 2027, Evaluating the Substance of Transactions Involving the Legal Form of a Lease.

K-IFRS No. 1116, at the inception date of a contract and the first implementation of the standard, requires the Group to determine whether a contract is, or contains, a lease unless the Group applies the practical expedient for the existing lease contract at the date of adoption of the standard.

When accounting for lease, lessee and lessor should account for each lease component within the contract as a lease separately from non-lease components of the contract.

Lessee recognizes a right-of-use asset representing its right to use the underlying asset and a lease liability representing its obligation to make lease payments. However, there are optional exemptions for short-term leases and leases of low value items. As a practical expedient, a lessee may elect, by class of underlying asset, not to separate non-lease components from lease components, and instead account for each lease component and any associated non-lease components as a single lease component.

Lessor accounting remains similar to the current standard K-IFRS No. 1017. For a sale and leaseback arrangement, K-IFRS No. 1116 requires the Group to apply the requirements for determining when a performance obligation is satisfied in K-IFRS No. 1115 to determine whether the transfer of an asset is accounted for as a sale of that asset. However, sale and leaseback arrangements entered into before the adoption of K-IFRS No. 1116 may not be reassessed.

i) Lease accounting for lessees

As a lessee, the Group can either apply the K-IFRS No. 1116 using a full retrospective approach; or modified retrospective approach. The full retrospective approach requires the Group to retrospectively apply the new standard to each prior reporting period presented, while modified retrospective approach requires the lessee to recognize the cumulative effect of initial application at the date of initial application of the new leases standard.

ii) Lease accounting for lessors

In case where the Group is an intermediate lessor, the Group should reassess subleases that were classified as operating leases applying K-IFRS No. 1017 and are ongoing at the date of initial application, whether each sublease should be classified as an operating lease or a finance lease applying K-IFRS No. 1116. For subleases that were classified as operating leases applying K-IFRS No. 1017 but finance leases applying K-IFRS No. 1116, the Group should accounts for such sublease as a new finance lease entered into at the date of initial application of K-IFRS No. 1116.

The Group plans to update its accounting system and related controls and complete the assessment of impact on its consolidated financial statements resulting from the adoption of K-IFRS No. 1116 by December 31, 2018.

The recoverable amount of the CGU is based on its value in use calculated by applying the annual discount rate of 5.1% to the estimated future cash flows based on financial budgets for the next five years.

		W	160,068		W	1,949,485

In addition, the Group has entered into cross currency swaps to hedge against currency risk related to foreign currency borrowings and debentures. (Refer to Note 20)

As of December 31, 2017, a hypothetical change in exchange rates by 10% would have increase (reduce) the Groups income before income tax as follows:

(In millions of won)	If increased by 10%	If decreased by 10%

(ii) Equity price risk

The Group has listed and non-listed equity securities for its liquidity management and operating purpose. As of December 31, 2017, available-for-sale equity instruments measured at fair value amount to W 734,487 million.

(iii) Interest rate risk

The interest rate risk of the Group arises from borrowings and debenture. Since the Groups interest bearing assets are mostly fixed-interest bearing assets, the Groups revenue and operating cash flows are not influenced by the changes in market interest rates.

Accordingly, 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, 2017, the floating-rate borrowings and bonds of the Group are W 228,300 million and W 321,420 million, respectively, and the Group has entered into interest rate swap agreements, as described in Note 20, for all floating-rate rate borrowings and debentures to hedge interest rate risk.

If the interest rate increases (decreases) 1% with all other variables held constant, income before income taxes for the year ended December 31, 2017, would change by W 707 million in relation to floating-rate borrowings that are exposed to interest rate risk.

2) Credit risk

The maximum credit exposure as of December 31, 2017 and 2016 are as follows:

(In millions of won)	2017	2016
Cash and cash equivalents	W	1,457,416	1,505,082
Financial instruments		618,002	469,705

Derivative financial assets		30,956	214,770
	W	6,227,140	6,158,872

Credit risk is the risk of financial loss to the Group if a customer or counterparty to a financial instrument fails to meet his/her contractual obligations.

To manage credit risk, the Group evaluates the credit worthiness of each customer or counterparty considering the partys 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 an allowance for doubtful account that represents its estimate of incurred losses in respect of trade and other receivables. 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 have been incurred but not yet identified. The collective loss allowance is determined based on historical data of payment statistics for similar financial assets. Also, the Groups credit risk can arise due to 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 December 31, 2017.

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.

Available-for-sale financial assets amounting to W 199,903 million and W 194,600 million as of December 31, 2017 and December 31, 2016, respectively, are measured at cost in accordance with K-IFRS No. 1039 since they are equity instruments which do not have quoted price in an active market for the identical instruments and for which fair value cannot be reliably measured using other valuation methods.

The Group uses various valuation methods for determination of fair value of financial instruments that are not traded in an active market. Fair value of available-for-sale securities is determined using the market approach methods and financial assets through profit or loss are measured using the option pricing model. In addition, derivative financial contracts and long-term liabilities are measured using the discounted present value methods. 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.

Borrowings and debentures	2.48% ~ 2.55%
Long-term payables other	2.23% ~ 2.60%

(*) The Group holds redeemable convertible preferred shares issued by Bluehole INC. The conversion rights attached to the investments are bifurcated from the host contract as embedded derivatives and the Group recognized W 222,257 million as financial assets at FVTPL and gain on valuation of derivatives, respectively, as of and during the year ended December 31, 2017. The host contract was recognized as available-for-sale financial assets of W 15,342 million measured by discounting the amount of collection at maturity including the principal, guaranteed interests, and dividend. The fair value of the conversion rights were measured using the binomial option pricing model by considering inputs such as expected volatility, exercise price, and common share price.

The major inputs used and their correlations with the fair value measurements are as follows.

Significant non-observable inputs	Correlations between inputs and fair value measurements
Value of common shares	If the value of common share increases (decreases), Fair value will increase (decrease)
Exercise price	If the exercise price increases (decreases), Fair value will decrease (increase)
Discount rate	If the discount rate increases (decreases), Fair value will decrease (increase)
Volatility	If the share price volatility increases (decreases), Fair value will increase (decrease)
