Won 2 trillion of the loan matures in three years and Won 0.5 trillion of the loan matures in one year.

[SK Broadband]

SK Broadband, a material consolidated subsidiary of ours, acquired subscriberships of regional cable and other service providers on several different occasions. Such acquisitions were intended to secure a stable subscriber base for our broadband Internet service and, at the same time, increase the service coverage area. Because such acquisitions were conducted on a relatively small scale and involved purchase of subscriberships, we did not believe such acquisitions rose to the level of purchasing an entire business line from another company or were likely to have a material impact on our business, and therefore we believed that such acquisitions did not require resolutions of our shareholders.

[Wireless Business]

A. Industry Characteristics

As of March 31, 2013, the Korean mobile communication market can be 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 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 HSPA+ network commercialized in October 2010 and the LTE network introduced in July 2011, B2B businesses, such as the corporate connected workforce business which can directly contribute to an enhancement in productivity, are expected to grow rapidly.

C. Domestic and Overseas Market Conditions

The Korean mobile communication market includes the entire population of Korea with mobile communication service needs, and almost every Korean is considered a potential user. Sales revenue related to data services is expected to increase due to the increasing popularity of smartphones and wireless Internet. The importance of the business-to-business segment, which creates added value by selling and developing various solutions, is also growing. 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 telecommunication service provider into a comprehensive information and communication technology (ICT) service provider. It has continued to expand the scope of its services and achieved strong growth in subscribers amid fierce competition and rate cuts. For the quarter ended March 31, 2013, the Company recorded Won 4.1 trillion in operating revenue and Won 410 billion in operating income on a consolidated basis and Won 3.1 trillion in revenue and Won 420 billion in operating income on a separate basis.

The number of subscribers as of March 31, 2013 was 27.03 million, an increase of approximately 68,000 from the previous quarter. In particular, the number of smartphone subscribers as of March 31, 2013 was 16.65 million, an increase of approximately 670,000 from the previous quarter, including 9.33 million LTE subscribers, solidifying the Companys market leadership. The Company upgraded the quality of data services by providing commercial LTE services, enabling streaming of high-quality videos, high-definition voice services such as high-definition video conference calls and joyn.T, an all-IP next generation integrated communications service. The Company also plans to enhance customer satisfaction by improving network quality.

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 16 years, 15 years and 13 years, respectively.

Table of Contents

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, 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 with lower average revenue per user. An MVNO leases the networks of a mobile network operator (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 products to customers, including mobile office products to business customers.

PS&Marketing, a subsidiary of the Company involved in wholesale, retail and online sales, offers fixed-line and wireless telecommunication products and services to meet the lifestyle needs of customers.

[Fixed-line Business]

A. Industry Characteristics

Mergers among fixed-line operators and wireless operators have accelerated the convergence within the Korean telecommunications industry, creating a market structure in which groups with both fixed-line and wireless capabilities compete for greater market share to secure a more solid footing in the market by lowering rates, such as introducing plans with unlimited minutes for both inter- and intra-network calls. In addition, with the introduction of smartphones, tablet computers and other devices with enhanced mobility and the expansion of LTE service (including the planned launch of LTE-Advanced service in the second half of 2013), wireless Internet usage has become a norm. As subscribers to various bundled wireless and fixed-line products are continuing to increase, subscribers to IPTV services are rapidly increasing. The market for our corporate business is also growing with cloud computing, mobile offices and other new information and communications technologies being commercialized. The increased usage of smartphones and tablet computers has greatly increased the demand for wireless data transmissions, thereby further emphasizing the importance of fixed-line networks.

The number of subscribers of the Companys IPTV services has reached over 6.7 million in four years since the Company launched this service and the Company continues to strengthen its position in the pay television market. In addition, with the increase in the number of smartphones, tablet PCs and other mobile devices, new services such as mobile IPTV and N-screen services are expected to grow significantly in the future.

C. Cyclical Nature and Seasonality

High-speed Internet, fixed-line telephone and IPTV services are mature markets that are generally not sensitive to cyclical economic changes due to the easing of competition resulting from the decrease in differentiation between service providers and the nature of the respective services. We expect that the accelerated transition to digital TV services as a result of the termination of analog open air TV broadcasting, as well as the entrance of Google Inc. (Google) and Apple Inc. (Apple) into the television market and the introduction of smart TV products, will present opportunities by expanding the market size and increasing consumers interests. We are strengthening our competitiveness in the TV business by expanding the number of popular channels, such as kids channels and channels providing live broadcasts of MLB games, as well as strengthening mobile IPTV services using N-screen.

D. Business Overview and Competitive Strengths

SK Broadband, which in 1999 became the first company in the world to commence commercial ADSL services, has strengthened its co-marketing efforts with SK Telecom. The co-marketing efforts and the enhanced competitiveness of the bundled products have resulted in an expanded subscriber base across all of our businesses, including broadband Internet, telephone and IPTV. In particular, we have positioned ourselves to focus on corporate customer services as one of the key strategic areas for mid- to long-term growth, and our efforts to exploit new information and communications technology-based businesses have led to revenue growth and strengthening of our competitiveness in the emerging business-to-business market.

SK Telink, a material consolidated subsidiary of the Company, provides international telecommunications service. SK Telink 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 us to expand our international calling services to fixed-line international calling services. SK Telink plans to strengthen its existing business, including international and long-distance calling services, value-added services for local calling and B2B services, while satisfying customers diverse needs for new services.

[Other Business]

A. Industry Characteristics

As the number of smartphones distributed in Korea exceeds 30 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.

Table of Contents

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, T Store). Platform businesses are evolving and expanding globally. It is becoming increasingly important to enhance competitiveness by creating a database that can register and analyze purchase patterns of customers across all areas and building a platform with large data capacity to utilize this database to provide differentiated services.

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.

B. Growth Potential

The Company expects that the scope and value generated by the platform business, including application and content marketplaces and N-screen services, will 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 are growing, which include 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. We expect that in the future, the importance of building a platform with large data capacity that is connected to various digital contents and commerce will increase.

C. Domestic and Overseas Market Conditions

(1) Competition

Application Marketplace

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.

Commerce Markets

The Company expects that on-line commerce markets will continue to grow due to the growth potential of the Internet shopping population and the strengthening of on-line business models by off-line operators. The Korean advertising market is expected to grow from Won 9.8 trillion in 2012 to Won 11.7 trillion in 2015. In particular, mobile advertising is expected to grow rapidly to Won 1.0 trillion in 2015, primarily due to the popularity of smartphones and convergence with location-based advertising.

Media Contents Market

Due to an increase in the number of devices owned by each user and an increase in network speed, each user can now enjoy music or video files anywhere and anytime by storing them in cloud servers, which is called N-screen service. Users can recommend music to other users through social networking services and this is expected to become a distribution model for digital media contents. Various service providers are competing in this market expecting a strong growth in the on-line and mobile video market.

Table of Contents

Although Internet portal service providers provide more or less identical types of services, including search, social networking, email, news and other content services, for each type of service, a small number of service providers with specialized expertise are enjoying relatively large market shares. However, the portal services market has a relatively low entry barrier and there is increased competition from new entrants. In addition, the ease of access to services provided by competitive foreign providers is also adding to a highly competitive market environment.

(2) Market Share

CyWorld service, our social networking website in Korea, had 26 million cumulative subscribers, 13 million net users and a page view of 500 million as of March 2013. Our Nate-On service had the largest market share of 73.6% in the instant messenger market in Korea with 8 million net users as of March 2013. Our Nate search portal service had a market share of 1.8% as of March 2013. (Source: Korean Click, Company data).

D. Business Overview and Competitive Strengths

The Companys Hoppin service, which provides N-screen media service enabling subscribers to enjoy video on demand through a number of N-screen compatible devices, including smartphones, tablets and PCs. Through continual service improvements and stable service provision, Hoppin has become the leading mobile video on demand service with over 300 million subscribers as of October 2012. The Company plans to market this service globally based on its experience in the Korean IT infrastructure environment.

Commerce (Open Market)

11th Street, 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 and is also firmly establishing its position as the leader in the mobile commerce market. Growth plans involving overseas joint ventures based on 11th Streets business expertise have resulted in the successful launch of an open online commerce market in Turkey in partnership with Doğuş Group.

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. With 36 million subscribers, OK Cashbag maintains a leading position in the industry and plans to continue strengthening its position by providing customized services befitting customers needs and market conditions.

Table of Contents

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.

Media Platform

The Companys media platform business started with its Hoppin service, which provides N-screen media service enabling subscribers to enjoy contents through a number of devices. Hoppin has expanded its services to more types of smartphones and tablets and has 3.73 million subscribers as of March 31, 2013. The Company plans to develop Hoppin service into a media platform acting as an intermediary of various N-screen services. It also plans to provide media platform services in overseas markets in stages.

Music Business

The Companys online music site, MelOn, has continued to increase its sales and, for the past five years, has been recognized as having the largest market share and the highest brand recognition in the digital music sales market in Korea. As of March 31, 2013, the Company supports all major smartphone and tablet devices introduced in Korea. The Company is quickly and flexibly responding to the mobile environment by improving the usability of its mobile applications, proactively responding to the release of new devices and continuing to improve its service and maintain its stable operation. The Company has also established a multi-device environment in which users can use MelOn anywhere and anytime, by among other things supporting all five major web browsers, including Explorer, Google Chrome and Safari. The Company is leading the growth of the music industry while respecting the rights of copyright holders. Despite changes in licensing fee requirements, the Company is pioneering new business areas by creating new products and services to meet the needs of a wide range of customers and partnering with various companies. The Company plans to strengthen its leadership in the mobile market and increase the number of its subscribers by providing reliable service operations and continually improving service, offering relevant and special music related contents to its customers and engaging in diverse and differentiated marketing promotion activities.

※ Satellite DMB

The Company launched its Hanbyul satellite in 2004 and received government approval in December 30, 2004 to provide satellite DMB services. Broadcasting through satellite DMB commenced in May 2005 and satellite DMB services expanded nationwide thereafter. On August 23, 2012, the board of directors resolved to discontinue operation of its satellite DMB services due to the rapid decrease in satellite DMB subscribers and the continued burden of fixed costs.

(2) Presentation of Financial Statements

The Company adopted the amendments pursuant to the amended K-IFRS No. 1001, Presentation of Financial Statements starting with the year ended December 31, 2012. The Companys operating income is calculated as operating revenue less operating expense.

The standard introduces a single control model to determine whether an investee should be consolidated. Subsidiary is an entity that is controlled by a controlling entity or a subsidiary of a controlling company.

Table of Contents

(3) Joint Arrangements

The Company has applied the amendments to K-IFRS No. 1111, Joint Arrangements since January 1, 2013. The standard classifies joint arrangements into two types - joint operations and joint ventures. A joint operation is a joint arrangement whereby the parties that have joint control of the arrangement (i.e. joint operators) have rights to the assets, and obligations for the liabilities, relating to the arrangement. A joint venture is a joint arrangement whereby the parties that have joint control of the arrangement (i.e. joint ventures) have rights to the net assets of the arrangement. The standard requires a joint operator to recognize and measure the assets and liabilities (and recognize the related revenues and expenses) in relation to its interest in the arrangement in accordance with relevant IFRSs applicable to the particular assets, liabilities, revenues and expenses. The standard requires a joint venture to recognize an investment and to account for that investment using the equity method.

(4) Disclosure of Interests in Other Entities

The Company has applied the amendments to K-IFRS No. 1112, Disclosure of Interests in Other Entities since January 1, 2013. The standard brings together into a single standard all the disclosure requirements about an entitys interests in subsidiaries, joint arrangements, associates and unconsolidated structured entities. The Company is currently assessing the disclosure requirements for interests in subsidiaries, interests in joint arrangements and associates and unconsolidated structured entities in comparison with the existing disclosures. The standard requires the disclosure of information about the nature, risks and financial effects of these interests.

(5) Employee Benefits

The Company has applied the amendments to K-IFRS No. 1019, Employee Benefits since January 1, 2013. The standard requires recognition of actuarial gains and losses immediately in other comprehensive income and to calculate expected return on plan assets based on the rate used to discount the defined benefit obligation.

(6) Fair Value Measurement

The Company has applied the amendments to K-IFRS No. 1113, Fair Value Measurement since January 1, 2013. The standard defines fair value and a single framework for fair value, and requires disclosures about fair value measurements.

D. Impact of Changes in Accounting Policies

(3) Joint Arrangements

The Company has applied the amendments to K-IFRS No. 1111, Joint Arrangements since January 1, 2013. The standard classifies joint arrangements into two types - joint operations and joint ventures. A joint operation is a joint arrangement whereby the parties that have joint control of the arrangement (i.e. joint operators) have rights to the assets, and obligations for the liabilities, relating to the arrangement. A joint venture is a joint arrangement whereby the parties that have joint control of the arrangement (i.e. joint venturers) have rights to the net assets of the arrangement. The standard requires a joint operator to recognize and measure the assets and liabilities (and recognize the related revenues and expenses) in relation to its interest in the arrangement in accordance with relevant IFRSs applicable to the particular assets, liabilities, revenues and expenses. The standard requires a joint venturer to recognize an investment and to account for that investment using the equity method.

Contingent Liabilities

[SK Telecom]

A. Material Legal Proceedings

(1) Claim for Copyright License Fees regarding Coloring Services

On May 7, 2010, Korea Music Copyright Association (KOMCA) filed a lawsuit with the court demanding that the Company pay KOMCA license fees for the Companys Coloring services. The court rendered a judgment against the Company ordering the Company to pay Won 570 million to KOMCA, which was affirmed by the appellate court on October 26, 2011. The Company appealed to the Supreme Court on November 8, 2011. The Company plans to vigorously defend itself in the Supreme Court by supplementing legal analysis relating to the interpretation of legal actions. While the Company does not expect this litigation to have an immediate impact on its business or results of operation because the judgment amount is Won 570 million and the final outcome of the litigation has not been decided, the Company may be required to pay increased on-going license fees in the future if the final judgment is rendered against it.

Actual impact on the Companys business and financial condition from the litigation may be different from the Companys expectation stated above.

B. Other Matters

(1) Pledged Assets and Covenants

SK Broadband has provided geun mortgage amounting to Won 15.2 billion to others, including Ilsan Guksa, on a part of its buildings in connection with the leasing of the buildings.

In 2011, PS&Marketing, a consolidated subsidiary of the Company, entered into a loan agreement to borrow up to Won 40 billion of working capital from Shinhan Bank. In connection with the loan agreement, it pledged Won 52 billion of its inventories to Shinhan Bank as collateral.

(2) Payment Guarantee by the Company

The Company is participating in the tactical aeronautics project of the Defense Acquisition Program Administration of Korea (the DAPA), together with the Joint Defense Corporation. The Company has guaranteed the payment of US$3,897,196 that the DAPA has prepaid to the Joint Defense Corporation.

Independent Auditors Review Report

Based on a report originally issued in Korean

To The Board of Directors and Shareholders

SK Telecom Co., Ltd.:

Reviewed financial statements

We have reviewed the accompanying condensed consolidated interim financial statements of SK Telecom Co., Ltd. and its subsidiaries (the Group), which comprise the condensed consolidated statement of financial position as of March 31, 2013, the related condensed consolidated statements of income, comprehensive income, changes in equity and cash flows for the three-month periods ended March 31, 2013 and 2012 and notes, comprising a summary of significant accounting policies and other explanatory information.

We did not review the financial statements of SK Broadband Co., Ltd., a domestic subsidiary, and an associate, whose financial statements constitute 19.6% of the Groups consolidated total assets as of March 31, 2013 and 11.9% (2012: 15.2%) of the Groups consolidated operating revenue for the three-month period ended March 31, 2013. Other auditors reviewed those financial statements and our report, insofar as it relates to the amounts included for these entities, is based solely on the reports of other auditors.

Managements responsibility

Management is responsible for the preparation and fair presentation of these condensed consolidated interim financial statements in accordance with Korean International Financial Reporting Standards (K-IFRS) No.1034, Interim Financial Reporting, and for such internal controls as management determines necessary to enable the preparation of condensed consolidated interim financial statements that are free from material misstatement, whether due to fraud or error.

Auditors responsibility

Our responsibility is to issue a report on these condensed consolidated interim financial statements based on our reviews.

We conducted our reviews in accordance with the Review Standards for Quarterly and Semiannual Financial Statements established by the Securities and Futures Commission of the Republic of Korea. A review consists principally of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with auditing standards generally accepted in the Republic of Korea and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

Based on our reviews and the reports of other auditors, nothing has come to our attention that causes us to believe that the accompanying condensed consolidated interim financial statements referred to above are not prepared fairly, in all material respects, in accordance with K-IFRS No.1034 Interim Financial Reporting.

Table of Contents

Highlights

As discussed in note 35, during the three-month period ended June 30, 2012 the Group decided to discontinue the broadcasting business operation due to the accumulating losses resulting from the continuing decline in satellite digital multimedia broadcasting subscribers. The Group has presented operating results of this broadcasting business as loss from discontinued operation and accordingly restated the comparative information of the statement of income for the three-month period ended March 31, 2012.

As discussed in note 3 to the condensed consolidated interim financial statements, the Group adopted amendments to K-IFRS No.1001, Presentation of Financial Statements from the interim period ended September 30, 2012 and separately presents operating income on the consolidated statements of income, which is calculated as operating revenue less operating expense. The Group applied this change in accounting policies retrospectively and accordingly restated the comparative information of the consolidated statement of income for the three-month period ended March 31, 2012.

Other matters

The statement of financial position of the Group as of December 31, 2012, and the related consolidated statements of income, comprehensive income, changes in equity and cash flows for the year then ended, which are not accompanying this report, were audited by us and our report thereon, dated February 22, 2013, expressed an unqualified opinion. The accompanying condensed consolidated statement of financial position of the Group as of December 31, 2012, presented for comparative purposes, is not different from that audited by us in all material respects.

The procedures and practices utilized in the Republic of Korea to review such condensed consolidated interim financial statements may differ from those generally accepted and applied in other countries. Accordingly, this report and the accompanying condensed consolidated interim financial statements are for use by those knowledgeable about Korean review standards and their application in practice.

Certain subsequent events or circumstances, which may occur between the review report date and the time of reading this report, could have a material impact on the accompanying condensed consolidated interim financial statements and notes thereto. Accordingly, the readers of the review report should understand that the above review report has not been updated to reflect the impact of such subsequent events or circumstances, if any.

Basis of Preparation

(1) Statement of compliance

The condensed consolidated interim financial statements have been prepared in accordance with Korean International Financial Reporting Standards (K-IFRS), as prescribed in the Act on External Audits of Stock Companies .

These condensed consolidated interim financial statements were prepared in accordance with K-IFRS No. 1034, Interim Financial Reporting as part of the period covered by the Groups K-IFRS annual financial statements. Selected explanatory notes are included to explain events and transactions that are significant to an understanding of the changes in financial position and performance of the Group since the last annual consolidated financial statements as at and for the year ended December 31, 2012. These condensed consolidated interim financial statements do not include all of the disclosures required for full annual financial statements.

(2) Use of estimates and judgments

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

In preparing these condensed consolidated interim financial statements, the significant judgments made by management in applying the Groups accounting policies and the key sources of estimation uncertainty were the same as those that applied to the consolidated financial statements as of and for the year ended December 31, 2012.

(3) Common control transactions

SK Holdings Co., Ltd. (the Ultimate Controlling Entity) is the Ultimate Controlling Entity of the Parent Company because it has de facto control of the Parent Company. Accordingly, gains and losses from business acquisitions and dispositions involving entities that are under the control of the Ultimate Controlling Entity are accounted for as common control transactions within equity.

Significant Accounting Policies

Except as described below, the accounting policies applied by the Group in these condensed consolidated interim financial statements are the same as those applied by the Group in its consolidated financial statements as of and for the year ended December 31, 2012. The following changes in accounting policy are also expected to be reflected in the Groups consolidated financial statements as at and for the year ending December 31, 2013.

(1) Changes in accounting policies

1) K-IFRS No. 1001, Presentation of Financial Statements

The Group has applied the amendments to K-IFRS No. 1001, Presentation of Financial Statements since January 1, 2013, classified items within other comprehensive income by nature and presented items that are not subsequently recycled through profit or loss and items that are subsequently reclassified if certain conditions are met as a group.

2) K-IFRS No.1110, Consolidated Financial Statements

The Group has applied the amendments to K-IFRS No. 1110, Consolidated Financial Statements since January 1, 2013. The standard introduces a single control model to determine whether an investee should be consolidated. Subsidiary is an entity that is controlled by a controlling entity or a subsidiary of a controlling company. A controlling entity or a subsidiary of a controlling company controls a subsidiary when the controlling entity or the subsidiary of the controlling company is exposed, or has rights, to variable returns from its involvement with the subsidiary and has the ability to affect those returns through its power over the subsidiary.

3) K-IFRS No.1111, Joint Arrangements

The Group has applied the amendments to K-IFRS No. 1111, Joint Arrangements since January 1, 2013. The standard classifies joint arrangements into two types - joint operations and joint ventures. A joint operation is a joint arrangement whereby the parties that have joint control of the arrangement (i.e. joint operators) have rights to the assets, and obligations for the liabilities, relating to the arrangement. A joint venture is a joint arrangement whereby the parties that have joint control of the arrangement (i.e. joint ventures) have rights to the net assets of the arrangement. The standard requires a joint operator to recognize and measure the assets and liabilities (and recognize the related revenues and expenses) in relation to its interest in the arrangement in accordance with relevant IFRSs applicable to the particular assets, liabilities, revenues and expenses. The standard requires a joint venture to recognize an investment and to account for that investment using the equity method.

4) K-IFRS No.1112, Disclosure of Interests in Other Entities

The Group has applied the amendments to K-IFRS No. 1112, Disclosure of Interests in Other Entities since January 1, 2013. The standard brings together into a single standard all the disclosure requirements about an entitys interests in subsidiaries, joint arrangements, associates and unconsolidated structured entities. The Group is currently assessing the disclosure requirements for interests in subsidiaries, interests in joint arrangements and associates and unconsolidated structured entities in comparison with the existing disclosures. The standard requires the disclosure of information about the nature, risks and financial effects of these interests.

The standard requires recognition of actuarial gains and losses immediately in other comprehensive income and to calculate expected return on plan assets based on the rate used to discount the defined benefit obligation.

6) Amendments to K-IFRS No. 1113, Fair Value Measurement

The Group has applied the amendments to K-IFRS No. 1113, Fair Value Measurement since January 1, 2013. The standard defines fair value and a single framework for fair value, and requires disclosures about fair value measurements.

(2) Impact of changes in accounting policies

1) K-IFRS No.1110, Consolidated Financial Statements

In accordance with the transitional provision on K-IFRS No. 1110, the Group assessed control on investees as of January 1, 2013, the initial adoption date of the standard, and there have been no changes in subsidiaries upon adoption of the standard.

2) K-IFRS No. 1001, Presentation of Financial Statements

The Group early adopted the amendments to K-IFRS No. 1001, Presentation of Financial Statements since the interim period ended September 30, 2012 and separately present its operating income as operating revenue less operating expense on the consolidated statement of income.

As of March 31, 2013, effects on income (loss) before income tax as a result of change in exchange rate by 10% are as follows:

(iii) Interest rate risk

Since the Groups interest bearing assets are mostly fixed-interest bearing assets, as such, the Groups revenue and operating cash flow are not influenced by the changes in market interest rates. However, the Group still has interest rate risk arising from borrowings and debentures.

Accordingly, the Group performs various analysis of interest rate risk, which includes refinancing, renewal, alternative financing and hedging instrument option, to reduce interest rate risk and to optimize its financing.

(1) Financial risk management, Continued

The Groups interest rate risk arises from floating-rate borrowings and payables. As of March 31, 2013, floating-rate borrowings and debentures amount to ￦669,913 million and ￦111,210 million respectively, the Group has entered into interest rate swaps to hedge interest rate risk related to floating-rate borrowings and debentures. (Refer to Note 21) If interest rate only increases (decreases) by 1%, income before income taxes for the three-month period ended March 31, 2013 would not have been changed due to the interest expense from floating-rate borrowings and debentures.

2) Credit risk

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. The maximum credit exposure as of March 31, 2013 and December 31, 2012 are as follows:

(In millions of won)	March 31, 2013	December 31, 2012
Cash and cash equivalents	￦	1,124,348	920,125

Financial assets at fair value through profit or loss		16,983	16,045
	￦	6,089,650	5,461,163

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.

For the three-month period ended March 31, 2013, the Group has no trade and other receivables or loans which have indications of significant impairment loss or are overdue for a prolonged period. As a result, the Group believes that the possibility of default is remote. Also, the Groups credit risk can rise due to transactions with financial institutions related to its cash and cash equivalents, financial instruments and derivates. To minimize such risk, the Group has a policy to deal with high credit worthy financial institutions. The amount of maximum exposure to credit risk of the Group is the carrying amount of financial assets as of March 31, 2013.

In addition, the aging of trade and other receivables that are overdue at the end of the reporting period but not impaired is stated in Note 6 and the analysis of financial assets that are individually determined to be impaired at the end of the reporting period is stated in Note 28.

(3) Fair value

Fair value of the financial instruments that are traded in an active market is measured based on the quoted market price at the end of the reporting date. Disclosed market price of the financial assets held by the Group is the bid price.

Fair value of the financial instruments that are not traded in an active market is determined using the valuation method. The Group uses the various valuation methods and makes assumptions that are mainly based on market conditions existing at the end of each reporting period. Fair value of financial instruments such as long-term liabilities is measured using the various methods including estimated discounted cash flow method.

Fair values of accounts receivable trade, and accounts payable - trade are considered to be carrying amount less impairment and fair value of financial liabilities for the disclosure purpose is estimated by discounting contractual future cash flows using the current market interest rate used for the similar financial instruments by the Group.

Interest rates used by the Group for the fair value measurement as of March 31, 2013 are as follows:

	Interest rate
Derivative instruments	2.55~4.26%
Borrowings and debentures	2.81~2.82%

Conclusion

Based on our reviews, nothing has come to our attention that causes us to believe that the accompanying condensed separate interim financial statements referred to above are not prepared fairly, in all material respects, in accordance with K-IFRS No.1034 Interim Financial Reporting.

Highlights

As discussed in Note 3 to the condensed separate interim financial statements, the Company adopted amendments to K-IFRS No.1001, Presentation of Financial Statements from the interim period ended September 30, 2012 and separately presents operating income on the separate statements of income, which is calculated as operating revenue less operating expense. The Company applied this change in accounting policies retrospectively and accordingly restated the comparative information of the separate statement of income for the three-month ended March 31, 2012.

SK Telecom Co., Ltd. (the Company) was incorporated in March 1984 under the laws of Republic of Korea (Korea) to engage in providing cellular telephone communication services in Korea. The Company mainly provides wireless telecommunications in Korea. The Companys common shares and depositary receipts (DRs) are listed on the Stock Market of Korea Exchange, the New York Stock Exchange and the London Stock Exchange. As of March 31, 2013, the Companys total issued shares are held by the following:

Treasury stock	11,050,712	13.69
Total number of shares	80,745,711	100.00

Basis of Presentation

(1) Statement of compliance

The condensed separate interim financial statements have been prepared in accordance with Korean International Financial Reporting Standards (K-IFRS), as prescribed in the Act on External Audits of Stock Companies.

These condensed separate interim financial statements were prepared in accordance with K-IFRS No. 1034, Interim Financial Reporting as part of the period covered by the Companys K-IFRS annual financial statements. Selected explanatory notes are included to explain events and transactions that are significant to an understanding of the changes in financial position and performance of the Company since the last annual separate financial statements as at and for the year ended December 31, 2012. These condensed separate interim financial statements do not include all of the disclosures required for full annual financial statements.

These condensed interim financial statements are separate interim financial statements prepared in accordance with K-IFRS No.1027, Separate Financial Statements presented by a parent, an investor in an associate or a venture in a jointly controlled entity, in which the investments are accounted for on the basis of the direct equity interest rather than on the basis of the reported results and net assets of the investees.

(2) Use of estimates and judgments

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

In preparing these condensed separate interim financial statements, the significant judgments made by management in applying the Companys accounting policies and the key sources of estimation uncertainty were the same as those that applied to the financial statements as of and for the year ended December 31, 2012.

Basis of Presentation, Continued

(3) Common control transactions

SK Holdings Co., Ltd. (the Ultimate Controlling Entity) is the Ultimate Controlling Entity of the Company because it has de facto control of the Company. Accordingly, gains and losses from business acquisitions and dispositions involving entities that are under the control of the Ultimate Controlling Entity are accounted for as common control transactions within equity.

Significant Accounting Policies

Except as described below, the accounting policies applied by the Company in these condensed separate interim financial statements are the same as those applied by the Company in its separate financial statements as of and for the year ended December 31, 2012. The following changes in accounting policy are also expected to be reflected in the Companys separate financial statements as at and for the year ending December 31, 2013.

(1) Changes in accounting policies

1) K-IFRS No. 1001, Presentation of Financial Statements

2) K-IFRS No.1110, Consolidated Financial Statements

3) K-IFRS No.1111, Joint Arrangements

The Company has applied the amendments to K-IFRS No. 1111, Joint Arrangements since January 1, 2013. The standard classifies joint arrangements into two types - joint operations and joint ventures. A joint operation is a joint arrangement whereby the parties that have joint control of the arrangement (i.e. joint operators) have rights to the assets, and obligations for the liabilities, relating to the arrangement. A joint venture is a joint arrangement whereby the parties that have joint control of the arrangement (i.e. joint venturers) have rights to the net assets of the arrangement. The standard requires a joint operator to recognize and measure the assets and liabilities (and recognize the related revenues and expenses) in relation to its interest in the arrangement in accordance with relevant IFRSs applicable to the particular assets, liabilities, revenues and expenses. The standard requires a joint venturer to recognize an investment and to account for that investment using the equity method.

Financial Risk Management

(1) Financial risk management

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

The Companys financial assets under financial risk management consist of cash and cash equivalents, financial instruments, available-for-sale financial assets, trade and other receivables. Financial liabilities consist of trade and other payables, borrowings, and debentures.

1) Market risk

(i) Currency risk

The Company is exposed to currency risk mainly on exchange fluctuations on recognized assets and liabilities. The Company manages currency risk by currency forward, etc. if needed to hedge currency risk on business transactions. Currency risk occurs on forecasted transaction and recognized assets and liabilities which are denominated in a currency other than the functional currency of the Company.

The Company has equity securities which include listed and non-listed securities for its liquidity and operating purpose. As of March 31, 2013, available-for-sale equity instruments measured at fair value amounts to ￦696,754 million.

(iii) Interest rate risk

Since the Companys interest bearing assets are mostly fixed-interest bearing assets, as such, the Companys revenue and operating cash flow are not influenced by the changes in market interest rates. However, the Company still has interest rate risk arising from borrowings and debentures.

Accordingly, the Company performs various analysis of interest rate risk, which includes refinancing, renewal, alternative financing and hedging instrument option, to reduce interest rate risk and to optimize its financing.

Financial Risk Management, Continued

The Companys interest rate risk arises from floating-rate borrowings and payables. As of March 31, 2013, floating-rate debentures and borrowings amount to ￦669,913 million and ￦111,210 million, respectively, and the Company has entered into interest rate swaps to hedge interest rate risk related to floating-rate borrowings and debentures (Refer to Note 16). If interest rate only increases (decreases) by 1%, income before income taxes for the year ended March 31, 2013 would not have been changed due to the interest expense from floating-rate borrowings and debentures.

2) Credit risk

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. The maximum credit exposure as of March 31, 2013 and December 31, 2012 are as follows:

(In millions of won)	March 31, 2013	December 31, 2012

Financial assets at fair value through profit or loss		16,294	15,356
	￦	3,623,131	3,357,094

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.

For the three-month period ended March 31, 2013, the Company has no trade and other receivables or loans which have indications of significant impairment loss or are overdue for a prolonged period. As a result, the Company believes that the possibility of default is remote. Also, the Companys credit risk can rise due to transactions with financial institutions related to its cash and cash equivalents, financial instruments and derivates. To minimize such risk, the Company has a policy to deal with high credit worthy financial institutions. The amount of maximum exposure to credit risk of the Company is the carrying amount of financial assets as of March 31, 2013.

In addition, the aging of trade and other receivables that are overdue at the end of the reporting period but not impaired is stated in Note 5 and the analysis of financial assets that are individually determined to be impaired at the end of the reporting period is stated in Note 23.

(3) Fair value

Fair value of the financial instruments that are not traded in an active market is determined using the valuation method. The Company uses the various valuation methods and makes assumptions that are mainly based on market conditions existing at the end of each reporting period. Fair value of financial instruments such as long-term liabilities is measured using the various methods including estimated discounted cash flow method.

Fair values of accounts receivable - trade, and accounts payable - trade are considered to be carrying amount less impairment and fair value of financial liabilities for the disclosure purpose is estimated by discounting contractual future cash flows using the current market interest rate used for the similar financial instruments by the Company.

Interest rates used by the Company for the fair value measurement as of March 31, 2013 are as follows:

Derivative instruments	2.55~4.26 %
Borrowings and Debentures	2.82 %
