Our consolidated financial statements are expressed in Won and, solely for the convenience of the reader, the consolidated financial statements as of and for the year ended December 31, 2012 have been translated into United States dollars at the rate of ￦1,071.1 to US$1.00, the Market Average Exchange Rate in effect on December 31, 2012.

You should read the selected consolidated financial data below in conjunction with the Consolidated Financial Statements as of December 31, 2011 and 2012 and for each of the years in the

three-year period ended December 31, 2012, and the report of the independent registered public accounting firm on these statements included herein. These audited financial statements and the related notes have been prepared under International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”). The selected consolidated financial data for the three years ended December 31, 2012 have been derived from our audited consolidated financial statements.

In addition to preparing financial statements in accordance with IFRS as issued by the IASB included in this annual report, we also prepare financial statements in accordance with IFRS as adopted by the Republic of Korea (“K-IFRS”), which we are required to file with the Financial Services Commission and the Korea Exchange under the Financial Investment Services and Capital Markets Act of Korea. English translations of such financial statements are furnished to the Securities and Exchange Commission under Form 6-K. Beginning with our financial statements prepared in accordance with K-IFRS as of and for the year ended December 31, 2012, we are required to adopt certain amendments to K-IFRS No. 1001, Presentation of Financial Statements, as adopted by KASB in 2012, pursuant to which we present operating profit or loss as an amount of revenue less cost of sales and selling and administrative expenses. In our consolidated statements of income prepared in accordance with IFRS as issued by the IASB included in this annual report, such changes in presentation were not adopted. As a result, the presentation of results from operating activities in our consolidated statements of income prepared in accordance with IFRS as issued by the IASB included in this annual report differs from the presentation of operating profit or loss in the our consolidated statements of income prepared in accordance with K-IFRS. See “Item 5.A. Operating Results—Explanatory Note Regarding Presentation of Certain Financial Information under K-IFRS” for additional information. In accordance with rule amendments adopted by the U.S. Securities and Exchange Commission which became effective on March 4, 2008, we are not required to provide a reconciliation to U.S. GAAP.

The information set forth below is not necessarily indicative of the results of future operations and should be read in conjunction with “Item 5. Operating and Financial Review and Prospects” and our consolidated financial statements and related notes included in this annual report.

Item 3.B. Capitalization and Indebtedness

Not applicable

Item 3.C. Reasons for the Offer and Use of Proceeds

Not applicable.

Item 3.D. Risk Factors

You should carefully consider the following factors.

Risks Relating to Our Business

Competition in the Korean telecommunications industry is intense.

Competition in the telecommunications sector in Korea is intense. In recent years, business combinations in the telecommunications industry have significantly changed the competitive landscape of the Korean telecommunications industry. In particular, SK Telecom Co., Ltd. (or SK Telecom) acquired a controlling stake in Hanarotelecom Incorporated in 2008, which was renamed SK Broadband Co., Ltd. (or SK Broadband). The acquisition enabled SK Telecom to provide fixed-line telecommunications, broadband Internet access and Internet television (or IP-TV) services together with its mobile telecommunications services. On January 1, 2010, LG Dacom Corporation (or LG Dacom) and LG Powercom Co., Ltd. (or LG Powercom) merged into LG Telecom Co., Ltd., which subsequently changed its name to LG U+. The merger enabled LG U+ to provide a similar range of services as SK Telecom and us. Our inability to adapt to such changes in the competitive landscape could have a material adverse effect on our business, financial condition and results of operations.

In addition to our competition with integrated telecommunications service providers, we face increasing competition from specific service providers, such as Internet phone service providers, Internet text message service providers, voice resellers and call-back service providers. In recent years, the increasing popularity of Internet phone and free text message services, such as Skype and Kakao Talk, have had a negative impact on demand for our telecommunications and text message services while creating additional data transmission usage by our Internet and mobile subscribers. Our inability to adapt to such changes in the competitive landscape could have a material adverse effect on our business, financial condition and results of operations.

Mobile Service. We provide mobile services based on Wideband Code Division Multiple Access (or W-CDMA) technology and Long-Term Evolution (or LTE) technology. Competitors in the mobile telecommunications service industry are SK Telecom and LG U+. We had a market share of 30.8% as of December 31, 2012, making us the second largest mobile telecommunications service provider in Korea. SK Telecom had a market share of 50.3% as of December 31, 2012.

Mobile subscribers are allowed to switch their service provider while retaining the same mobile phone number. Mobile service providers also grant subsidies to subscribers who purchase new handsets and agree to a minimum subscription period. Mobile number portability and handset subsidies have intensified competition among the mobile service providers and increased their marketing expenses. If the mobile service providers adopt a strategy of expanding market share through price competition, it could lead to a decrease in our net profit margins.

Since 2011, SK Telecom, LG U+ and we have launched fourth-generation mobile telecommunications services based on LTE technology, which we believe has further intensified competition among the three companies and resulted in an increase in marketing expenses and capital expenditures related to implementing and providing 4G LTE services. SK Telecom and LG U+ began providing 4G LTE services in July 2011, and we commenced providing commercial 4G LTE services on January 3, 2012 utilizing our bandwidths in the 1.8 GHz spectrum that became available upon termination of our 2G services based on Code Division Multiple Access (or CDMA) technology. Although we expect that SK Telecom and LG U+ will face similar challenges to those that we expect to face in implementing this fourth-generation technology, we cannot assure you that we will continue to be able to successfully compete in fourth-generation mobile telecommunications services.

Fixed-line Telephone Services. Before December 1991, we were the sole provider of local, domestic long-distance and international long-distance telephone services in Korea. Since then, various competitors have entered the local, domestic long-distance and international long-distance telephone service markets in Korea, which have eroded our market shares. LG U+ and SK Broadband currently provide local, domestic long-distance and international long-distance telephone services. In addition, Onse Telecom Corporation and SK Telink, Inc. currently provide domestic long-distance and international long-distance telephone services. We also compete with specific service providers, such as Internet phone service providers, voice resellers and call-back service providers, that offer international long-distance service in Korea. While we offer our own Internet phone service, the entry of these and other potential competitors into the local, domestic long-distance and international long-distance telephone service markets has had and may continue to have a material adverse effect on our revenues and profitability from these businesses. As of December 31, 2012, we had a market share in local telephone service of 82.8% and a market share in domestic long distance service of 79.2%. Further increase in competition may decrease our market shares in such businesses.

Internet Services. The Korean broadband Internet access service market has experienced significant growth in the past decade. SK Broadband (formerly Hanarotelecom) entered the broadband market in 1999 offering both Hybrid Fiber Coaxial (or HFC) and Asymmetric Digital Subscriber Line (or ADSL) services. We also began offering broadband Internet access service in 1999, followed by Dreamline, Onse and LG U+. In recent years, numerous cable television operators have also begun to offer HFC-based services at rates lower than ours. We had a market share of 44.0% as of December 31, 2012. As a result of having to compete with a number of competitors and the maturing of the Internet access service market, we currently encounter, and we expect to encounter, pressure to increase marketing expenses in the future.

The market for other Internet-related services in Korea, including IP-TV and Internet phone services, is also very competitive. We anticipate that competition will continue to intensify as the usage and popularity of the Internet grows and as new domestic and international competitors enter the Internet industry in Korea. The substantial growth of the Internet industry in Korea has attracted many competitors and as a result may lead to increasing price competition to provide Internet-related services. Increased competition in the Internet industry could have a material adverse effect on the number of subscribers of our Internet-related service and on our results of operations.

Failure to renew existing bandwidth spectrum, acquire adequate additional bandwidth spectrum or use our bandwidth efficiently may adversely affect our mobile telecommunications business and results of operations.

One of the principal limitations on a wireless network’s subscriber capacity is the amount of bandwidth spectrum allocated to the service provider. We have a license to use 40 MHz of bandwidth in the 2.1 GHz spectrum that we use to provide IMT-2000 services based on W-CDMA wireless network standards. Such license expires in December 2016, and we are required to pay approximately

7

￦1.3 trillion during the license period of 15 years. In April 2010, the Korea Communications Commission announced its decision to allocate 20 MHz of bandwidth in the 900 MHz spectrum to us, which became effective in July 2011, for which we are required to pay a portion of the actual sales generated from using the bandwidth in the 900 MHz spectrum during the license period of 10 years as a usage fee for the bandwidth, as well as a portion of expected sales that was determined by the Korea Communications Commission at the time of allocation. In June 2011, our right to use 40 MHz of bandwidth in the 1.8 GHz spectrum expired, and the Korea Communications Commission allocated back to us the right to use 20 MHz of such bandwidth in the 1.8 GHz spectrum upon expiration pursuant to our application, for which we are required to pay a portion of the actual sales generated from using the bandwidth in the 1.8 GHz spectrum during the license period of 10 years as a usage fee for the bandwidth, as well as a portion of expected sales that was determined by the Korea Communications Commission at the time of allocation.

In August 2011, the Korea Communications Commission auctioned the right to use the remaining 20 MHz of bandwidth in the 1.8 GHz spectrum that we relinquished, 10 MHz of additional bandwidth in the 800 MHz spectrum and 20 MHz of additional bandwidth in the 2.1 GHz spectrum. We acquired the right to use the 10 MHz of bandwidth in the 800 MHz spectrum, for which we are required to pay a total usage fee of ￦261 billion during the license period of 10 years, SK Telecom acquired the right to use the 20 MHz of bandwidth in the 1.8 GHz spectrum and LG U+ acquired the right to use the 20 MHz bandwidth in the 2.1 GHz spectrum. We began using the 20 MHz of bandwidth in the 1.8 GHz spectrum, which became available upon termination of our 2G PCS services, to provide our 4G LTE services starting in January 2012, and expect to utilize the newly allocated bandwidths in the 800 MHz and 900 MHz spectrums to further expand our 4G LTE services in the future, if necessary. The Korea Communications Commission announced in December 2012 that it will further auction 60 MHz of bandwidth in the 1.8 GHz spectrum, which had been used by governmental entities such as the military, and 80 MHz of bandwidth in the 2.6 GHz spectrum, which had been used for digital multimedia broadcasting services. The auction is expected to take place in June 2013.

The growth of our mobile telecommunications business and the increase in usage of wireless data transmission services have been significant factors in the increased utilization of our bandwidth, since wireless data applications are generally more bandwidth-intensive than voice services. The current trend of increasing data transmission use and the increasing sophistication of multimedia contents are likely to put additional strain on the bandwidth capacity of mobile service providers. In the event we are unable to maintain sufficient bandwidth capacity by renewing existing bandwidth spectrum, receiving additional bandwidth allocation, or cost-effectively implementing technologies that enhance bandwidth usage efficiency, our subscribers may perceive a general decrease in quality of mobile telecommunications services. No assurance can be given that bandwidth constraints will not adversely affect the growth of our mobile telecommunications business.

Introduction of new services, including our 4G LTE services, poses challenges and risks to us.

The telecommunications industry is characterized by continual advances and improvements in telecommunications technology, and we have been continually researching and implementing technology upgrades and additional telecommunication services to maintain our competitiveness. For example, in March 2005, we acquired a license to provide wireless broadband Internet access (or WiBro) service for ￦126 billion, and commercially launched our service in June 2006. We completed the upgrade of our 4G WiBro network and expanded our WiBro service coverage to 84 cities nationwide and major highways in March 2011, which we believe allows us to provide WiBro services at speeds that are approximately three times faster than our previous 3G network at a lower cost, and had approximately 934,000 subscribers as of December 31, 2012. We are also upgrading our broadband network to enable FTTH connection, which enhances downstream speed and connection

8

quality. FTTH is a telecommunication architecture in which a communication path is provided over optical fiber cables extending from the telecommunications operator’s switching equipment to the boundary of home or office. FTTH uses fiber optic cable, which is able to carry a high-bandwidth signal for longer distances without degradation. FTTH enables us to deliver enhanced products and services that require high bandwidth, such as IP-TV service and delivery of other digital media content.

In addition, we have been building more advanced mobile telecommunications networks based on LTE technology, which is generally referred to as a 4G technology, and commenced providing commercial 4G LTE services in the Seoul metropolitan area on January 3, 2012. We completed the expansion of our 4G LTE service coverage nationwide in October 2012. Several wireless carriers in the United States, Europe and Asia commenced LTE services in recent years and LTE technology is expected to be widely accepted as the standard 4G technology. LTE technology enables data to be transmitted faster than W-CDMA, up to 75 Mbps for downloading and up to 37.5 Mbps for uploading. We believe that the faster data transmission speed of the LTE network, combined with our existing 4G nationwide WiBro network, allows us to offer significantly improved wireless data transmission services, providing our subscribers with faster wireless access to multimedia content. No assurance can be given that our new services will gain broad market acceptance such that we will be able to derive revenues from such services to justify the license fee, capital expenditures and other investments required to provide such services.

Termination of our second generation Personal Communications Service (or 2G PCS) services may pose risks to us.

As part of our decision to apply for reallocation of the 20 MHz bandwidth in the 1.8 GHz spectrum, we applied to the Korea Communications Commission to terminate our 2G PCS services, and on November 23, 2011, the Korea Communications Commission approved our plan. However, on November 30, 2011, approximately 900 of our 2G PCS service subscribers filed a class-action suit against the Korea Communications Commission for its approval of our plan, claiming that we used improper means to reduce our 2G PCS subscribers to comply with regulatory requirements before terminating the 2G PSC services and that the Korea Communications Commission did not consider such factor in approving our plan. On December 6, 2011, the Seoul Administrative Court issued a preliminary injunction, which temporarily suspended our termination of the 2G PCS services until the case went to trial. We immediately appealed the decision and the Seoul High Court overruled the preliminary injunction on December 26, 2011 and reinstated the Korea Communications Commission’s approval. Accordingly, we terminated our 2G PCS services in the Seoul metropolitan area and began the termination process for the rest of Korea on January 3, 2012. On January 12, 2012, the 2G subscribers filed an appeal of the Seoul High Court’s decision with the Supreme Court of Korea, and on February 1, 2012, the Supreme Court of Korea denied such appeal. On January 17, 2012, trial for the original class-action suit filed by the 2G subscribers began in the Seoul Administrative Court. On May 8, 2012, the Seoul Administrative court ruled in our favor on all claims and the plaintiffs subsequently filed an appeal with the Seoul High Court. On September 15, 2012, the Seoul High Court denied the plaintiffs’ appeal, and the plaintiffs appealed the decision to the Supreme Court of Korea. On February 15, 2013, the Supreme Court of Korea denied the plaintiffs’ appeal. There are currently three other similar appeals pending in the Supreme Court of Korea. While we expect these appeals to also be resolved in our favor, there can be no assurance that we will not incur reputational damage from terminating our 2G PCS services, or that further complaints and other potential actions of our 2G PCS subscribers will not adversely affect our business, financial condition and results of operations.

We may not be able to successfully pursue our strategy to acquire businesses and enter into joint ventures that complement or diversify our current business, and we may need to incur additional debt to finance such expansion activities.

One key aspect of our overall business strategy calls for acquisitions of businesses and entering into joint ventures that complement or diversify our current business. In October 2011, we, through our subsidiary KT Capital Co., Ltd., acquired 1,622,520 common shares of BC Card Co., Ltd. to further diversify our business and to create synergies through utilization of our mobile telecommunications network in financial services. In January 2011, we acquired 5,600,000 shares of redeemable convertible preferred stock with voting rights and convertible bonds that were convertible into 5,600,000 shares of common stock of KT Skylife Co., Ltd., a provider of satellite TV service which may also be packaged with our IP-TV services, from Dutch Savings Holdings B.V. for approximately ￦246 billion. We exercised the conversion rights on the redeemable convertible preferred stock and the convertible bonds in March 2011, and owned a 50.2% interest in KT Skylife Co., Ltd. as of December 31, 2012. In December 2012, we submitted a non-binding bid for Vivendi SA’s 53.0% controlling stake in Maroc Telecom SA, a telecommunications service provider based in Rabat, Morocco. While we announced our decision in March 2013 not to submit a formal bid for Maroc Telecom SA, we may consider various investment options with Maroc Telecom SA.

While we plan to continue our search for other suitable acquisition and joint venture opportunities, we cannot provide assurance that we will be able to identify additional attractive opportunities or that we will successfully complete the transactions, including the bid for Maroc Telcom SA, without encountering administrative, technical, political, financial or other difficulties, or at all. Even if we were to successfully complete the transactions, success of an acquisition or a joint venture depends largely on our ability to achieve the anticipated synergies, cost savings and growth opportunities from integrating the business of the acquired company or the joint venture with our business. There can be no assurance that we will achieve the anticipated benefits of the transaction, which may adversely affect our business, financial condition and results of operations.

Pursuing acquisitions or joint venture transactions also requires significant capital, and as we pursue further growth opportunities for the future, we may need to raise additional capital through incurring loans or through issuances of bonds or other securities in the international capital markets. The bid for Maroc Telcom SA may also require significant capital resources if our bid is eventually successful. However, we cannot guarantee that such capital will be available when needed due to conditions in the capital markets, or that even if such capital is available, it will be available on commercially acceptable terms or in sufficient amounts to make the expenditures required.

Disputes with our labor union may disrupt our business operations.

In the past, we have experienced opposition from our labor union for our strategy of restructuring to improve our efficiency and profitability by disposing of non-core businesses and reducing our employee base. Although we have not experienced any significant labor disputes or unrests in recent years, there can be no assurance that we will not experience labor disputes or unrests in the future, including expanded protests and strikes, which could disrupt our business operations and have an adverse effect on our financial condition and results of operations.

We also negotiate collective bargaining agreements every two years with our labor union and annually negotiate a wage agreement. Our current collective bargaining agreement expires on May 23, 2013. Although we have been able to reach collective bargaining agreements and wage agreements with our labor union in recent years, there can be no assurance that we will not experience labor disputes and unrests resulting from disagreements with the labor union in the future.

The Korean telecommunications and Internet protocol broadcasting industries are subject to extensive Government regulations, and changes in Government policy relating to these industries could have a material adverse effect on our operations and financial condition.

The Government, primarily through the Ministry of Science, ICT & Future Planning (the “MSIP”) (ICT standing for Information & Communication Technology) and the Korea Communications Commission, has authority to regulate the telecommunications industry. Until recently, regulation of the telecommunications industry has mainly been the responsibility of the Korea Communications Commission. With the establishment of the newly created MSIP on March 23, 2013, however, such regulatory responsibility has mostly been transferred to the MSIP. The MSIP’s policy is to promote competition in the Korean telecommunications markets through measures designed to prevent the dominant service provider in any such market from exercising its market power in such a way as to prevent the emergence and development of viable competitors.

Under current Government regulations, if a network service provider has the largest market share for a specified type of service and its revenue from that service for the previous year exceeds a specific revenue amount set by the MSIP, it must obtain prior approval from the MSIP for the rates and the general terms for that service. Each year the MSIP designates service providers the rates and the general terms of which must be approved by the Korea Communications Commission. In recent years, the Korea Communications Commission had so designated us for local telephone service and SK Telecom for mobile service, and the MSIP, in consultation with the Ministry of Strategy and Finance, currently approves rates charged by us and SK Telecom for such services.

The MSIP currently does not regulate our domestic long-distance, international long-distance, broadband internet access and mobile service rates, but the inability to freely set our local telephone service rates may hurt profits from such business and impede our ability to compete effectively against our competitors. See “Item 4. Information on the Company—Item 4.B. Business Overview—Regulation—Rates.” The form of our standard agreement for providing local network service and each agreement for interconnection with other service providers are also subject to approval by the MSIP. In addition, the MSIP may periodically announce public policy guidelines or suggestions that we take into consideration in setting our tariff for non-regulated services. In June 2011, upon recommendation of the Korea Communications Commission, SK Telecom announced tariff reduction measures, including a reduction of the monthly fee by ￦1,000 for every subscriber, an exemption of usage charges for short text message service, or SMS, up to 50 messages per month and the introduction of flexible service plans for smartphone users. In August 2011, after discussions with the Korea Communications Commission, we announced the adoption of various tariff reduction measures, including a reduction of the monthly fee by ￦1,000 for every mobile subscriber (effective October 21, 2011), an exemption of usage charges for SMS, of up to 50 messages per month (effective November 1, 2011) and the introduction of customized fixed rate plans for smartphone users (effective October 24, 2011). There can be no assurance that we will not adopt other tariff-reducing measures in the future to comply with the Government’s public policy guidelines or suggestions.

Based on investigations conducted in December 2012 and January 2013, the Korea Communications Commission imposed a combined fine of approximately ￦12 billion on SK Telecom, LG U+ and us in January 2013 (our fine being approximately ￦2.9 billion), for providing subsidies that were higher than those allowed under current regulations to new mobile phone purchasers and subscribers, and also imposed temporary suspensions from recruiting new customers ranging from 20 days to 24 days from signing new subscribers. In March 2013, the Korea Communications Commission again imposed a combined fine of approximately ￦5 billion on SK Telecom, LG U+ and us (our fine being approximately ￦1.6 billion), for continuing to offer subsidies during the suspension period.

President Park Geun-hye, who took office on February 25, 2013 as the 18th President of Korea, announced that the new Government will work toward reducing telecommunications service

11

charges and promoting transparency in the decision making of telecommunications service providers. Accordingly, the new Government has set detailed policy objectives to (1) gradually reduce and abolish initial subscription fees by 2015, (2) expand mobile virtual network operator and mobile voice over Internet protocol (“m-VoIP”) service, (3) intensify regulations on handset subsidies and (4) construct a data-based tariff system. If the new Government goes forward with its new telecommunications policy, it will increase competition among wireless service providers and our business and our profitability may be adversely affected.

The Government also sets the policies regarding the use of radio frequencies and allocates the spectrum of radio frequencies used for wireless telecommunications. For a discussion of the Government’s recent policies and practices on bandwidth spectrum allocation, see “Item 3. Key information—Item 3.D. Risk Factors—“Failure to renew existing bandwidth spectrum, acquire adequate additional bandwidth spectrum or use our bandwidth efficiently may adversely affect our mobile telecommunications business and results of operations.” The new allocations of bandwidth could increase competition among wireless service providers, which may have an adverse effect on our business.

We also plan to put more focus on the Internet protocol (or IP) media market, and we began offering IP-TV service in November 2008. IP-TV is a service which combines video-on-demand services with real-time high definition broadcasting via broadband networks. The MSIP and the Korea Communications Commission have the authority to regulate the IP media market, including IP-TV services. Under the Internet Multimedia Broadcasting Business Act, anyone intending to engage in the IP media broadcasting business must obtain a license from the MSIP, and anyone intending to engage in the production and dissemination of contents focused on news or contents generally combining news, culture, entertainment and other similar contents must obtain an additional approval from the Korea Communications Commission, and anyone intending to engage in the production and dissemination of contents relating to introduction of consumer products and other similar marketing contents must obtain an additional approval from the MSIP. In addition, KT Skylife Co. (formerly Korea Digital Satellite Broadcasting Co., Ltd.), which became our consolidated subsidiary starting in January 2011, offers satellite TV services, which may also be packaged with our IP-TV services. KT Skylife is also subject to the regulation of the MSIP pursuant to the Korea Broadcasting Act.

Government policies and regulations relating to the above as well as other regulations involving the Korean telecommunications and IP broadcasting industries (including as a result of the implementation of free trade agreements between Korea and other countries, including the United States and the European Union) may change, which could have a material adverse effect on our operations and financial condition. See “Item 4. Information on the Company—Item 4.B. Business Overview—Regulation.”

We are subject to various regulations under the Monopoly Regulation and Fair Trade Act.

The Monopoly Regulation and Fair Trade Act provides for various regulations and restrictions on large business groups enforced by the Korea Fair Trade Commission. The Korea Fair Trade Commission initially designated us as a large business group under the Monopoly Regulation and Fair Trade Act on April 1, 2002. Our business relationships and transactions with our subsidiaries, affiliates and other companies within the KT Group are subject to ongoing scrutiny by the Fair Trade Commission as to, among other things, whether such relationships and transactions constitute undue financial support among companies of the same business group. We are also subject to the fair trade regulations limiting debt guarantees for other domestic member companies of the same group and cross-shareholdings among domestic member companies of the same group. Any future determination

12

by the Korea Fair Trade Commission that we have engaged in transactions that violate the fair trade laws and regulations may result in fines or other punitive measures and may have a material adverse effect on our reputation and our business.

Concerns that radio frequency emissions may be linked to various health concerns could adversely affect our business and we could be subject to litigation relating to these health concerns.

In the past, allegations that serious health risks may result from the use of wireless telecommunications devices or other transmission equipment have adversely affected share prices of some wireless telecommunications companies in the United States. In May 2011, the International Agency for Research on Cancer (“IARC”) announced that it has classified radiofrequency electromagnetic fields associated with wireless phone use as possibly carcinogenic to humans, based on an increased risk for glioma, a malignant type of brain cancer. The IARC is part of the World Health Organization that conducts research on the causes of human cancer and the mechanisms of carcinogenesis, and aims to develop scientific strategies for cancer control. We cannot assure you that such health concerns will not adversely affect our business. Several class action and personal injury lawsuits have been filed in the United States against several wireless phone manufacturers and carriers, asserting product liability, breach of warranty and other claims relating to radio transmissions to and from wireless phones. Certain of these lawsuits have been dismissed. We could be subject to liability or incur significant costs defending lawsuits brought by our subscribers or other parties who claim to have been harmed by or as a result of our services. In addition, the actual or perceived risk of wireless telecommunications devices could have an adverse effect on us by reducing our number of subscribers or our usage per subscriber.

Depreciation of the value of the Won against the Dollar and other major foreign currencies may have a material adverse effect on the results of our operations and on the prices of our securities.

Substantially all of our revenues are denominated in Won. Depreciation of the Won may materially affect the results of our operations because, among other things, it causes an increase in the amount of Won required by us to make interest and principal payments on our foreign-currency-denominated debt, the costs of telecommunications equipment that we purchase from overseas sources, net settlement payments to foreign carriers and certain payments related to our derivative instruments entered into for foreign exchange risk hedging purposes. Of the ￦8,237 billion total principal amount of long-term borrowings (less current portion) outstanding as of December 31, 2012, ￦2,749 billion was denominated in foreign currencies with an average weighted interest rate of 3.90%. The interest rates of such long-term debt denominated in foreign currencies ranged from 1.36% (for US$100 million floating rate notes due 2013 with an interest rate of three month London Interbank Offered Rate plus 1.05%) to 6.50% (for US$100 million fixed rate notes due 2034 issued under our medium-term note program). Upon identification and evaluation of our currency risk exposures, we, having considered various circumstances, enter into derivative financial instruments to try to manage some of such risks. Although the impact of exchange rate fluctuations has in the past been partially mitigated by such strategies, our results of operations have historically been affected by exchange rate fluctuations and there can be no assurance that such strategies will be sufficient to reduce or eliminate the adverse impact of such fluctuations in the future. See “Item 3. Key Information—Item 3.A. Select Financial Data—Exchange Rate Information”, “Item 5. Operating and Financial Review and Prospects—Item 5.B. Liquidity and Capital Resources” and “Item 11. Quantitative and Qualitative Disclosures About Market Risk—Interest Rate Risk.”

Fluctuations in the exchange rate between the Won and the Dollar will also affect the Dollar equivalent of the Won price of the shares of our common stock on the KRX KOSPI Market and, as a

13

result, will likely affect the market price of the ADSs. These fluctuations will also affect the Dollar conversion by the depositary for the ADRs of cash dividends, if any, paid in Won on shares of common stock represented by the ADSs.

Risks Relating to Korea

Korea is our most important market, and our current business and future growth could be materially and adversely affected if economic conditions in Korea deteriorate.

Substantially all of our operations, customers and assets are located in Korea. Accordingly, the performance and successful fulfillment of our operational strategies are necessarily dependent on the overall Korean economy and the resulting impact on the demand for telecommunications services. The economic indicators in Korea in recent years have shown mixed signs of growth and uncertainty, and future growth of the Korean economy is subject to many factors beyond our control, including developments in the global economy.

In recent years, adverse conditions and volatility in the worldwide financial markets, fluctuations in oil and commodity prices and the general weakness of the U.S. and global economy have contributed to the uncertainty of global economic prospects in general and have adversely affected, and may continue to adversely affect, the Korean economy. From the second half of 2008 to the first half of 2010, the value of the Won relative to major foreign currencies in general and the U.S. dollar in particular fluctuated widely. While the value of the Korean Won generally stabilized starting in the second half of 2010, there have been signs of relative increase in the volatility of exchange rates starting in the fourth quarter of 2012. Given the lingering uncertainty in the global economic environment, there is no guarantee that exchange rates will not once again fluctuate in the future at such levels as we experienced in the second half 2008 through the first half of 2010. See “Item 3.A. Selected Financial Data—Exchange Rates.” A depreciation of the Won increases the cost of imported goods and services and the Won revenue needed by Korean companies to service foreign currency denominated debt. An appreciation of the Won, on the other hand, causes export products of Korean companies to be less competitive by raising their prices in terms of the relevant foreign currency and reduces the Won value of such export sales. Furthermore, as a result of adverse global and Korean economic conditions, there has been an overall decline and continuing volatility in the stock prices of Korean companies. The Korea Composite Stock Price Index, or KOSPI, declined from 1,897.1 on December 31, 2007 to 938.8 on October 24, 2008. While the KOSPI has recovered since 2008, closing at 1,944.6 on April 26, 2013, there is no guarantee that the stock prices of Korean companies will not decline again in the future. Future declines in the KOSPI and large amounts of sales of Korean securities by foreign investors and subsequent repatriation of the proceeds of such sales may continue to adversely affect the value of the Won, the foreign currency reserves held by financial institutions in Korea, and the ability of Korean companies to raise capital. Any future deterioration of the Korean or global economy could adversely affect our business, financial condition and results of operations.

Developments that could have an adverse impact on Korea’s economy in the future include:

• difficulties in the financial sectors in Europe and elsewhere and increased sovereign default risks in selected countries and the resulting adverse effects on the global financial markets;

• adverse changes or volatility in foreign currency reserve levels, commodity prices (including oil prices), exchange rates (including fluctuation of the U.S. dollar or Japanese Yen exchange rates or revaluation of the Chinese Renminbi), interest rates, inflation rates or stock markets;

• continuing adverse conditions in the economies of countries that are important export markets for Korea, such as the United States, Japan and China, or in emerging market economies in Asia or elsewhere;

14

• further decreases in the market prices of Korean real estate;

• increasing delinquencies and credit defaults by consumer and small- and medium-sized enterprise borrowers;

• declines in consumer confidence and a slowdown in consumer spending;

• the continued emergence of the Chinese economy, to the extent its benefits (such as increased exports to China) are outweighed by its costs (such as competition in export markets or for foreign investment and the relocation of the manufacturing base from Korea to China);

• social and labor unrest;

• a decrease in tax revenues and a substantial increase in the Korean government’s expenditures for fiscal stimulus measures, unemployment compensation and other economic and social programs that, together, would lead to an increased Korean government budget deficit;

• financial problems or lack of progress in the restructuring of large troubled companies, their suppliers or the financial sector;

• loss of investor confidence arising from corporate accounting irregularities or corporate governance issues at certain Korean companies;

• the economic impact of any pending or future free trade agreements;

• geo-political uncertainty and risk of further attacks by terrorist groups around the world;

• the occurrence of severe health epidemics in Korea or other parts of the world;

• deterioration in economic or diplomatic relations between Korea and its trading partners or allies, including deterioration resulting from territorial or trade disputes or disagreements in foreign policy;

• political uncertainty or increasing strife among or within political parties in Korea;

• natural disasters that have a significant adverse economic or other impact on Korea or its major trading partners;

• hostilities or political or social tensions involving oil producing countries in the Middle East or North Africa and any material disruption in the supply of oil or increase in the price of oil; and

• an increase in the level of tensions or an outbreak of hostilities between North Korea and Korea or the United States.

Escalations in tensions with North Korea could have an adverse effect on us.

Relations between Korea and North Korea have been tense throughout Korea’s modern history. The level of tension between the two Koreas has fluctuated and may increase abruptly as a result of future events. In particular, since the death of Kim Jong-il in December 2011, there has been increased uncertainty with respect to the future of North Korea’s political leadership and concern regarding its implications for political and economic stability in the region. Although Kim Jong-il’s third son, Kim Jong-eun, has assumed power as his father’s designated successor, the long-term outcome of such leadership transition remains uncertain.

15

In addition, there have been heightened security concerns in recent years stemming from North Korea’s nuclear weapon and long-range missile programs as well as its hostile military actions against Korea. Some of the significant incidents in recent years include the following:

• In early April 2013, North Korea blocked access to the inter-Korean industrial complex in its border city of Gaeseong to South Koreans, while the U.S. deployed nuclear-capable stealth bombers and destroyers to Korean air and sea space;

• In late March 2013, North Korea stated that it had entered “a state of war” with Korea, declaring the 1953 armistice invalid, and put its artillery at the highest level of combat readiness to protest the Korea-United States allies’ military drills and additional sanctions imposed on North Korea for its missile and nuclear tests;

• North Korea renounced its obligations under the Nuclear Non-Proliferation Treaty in January 2003 and conducted three rounds of nuclear tests between October 2006 to February 2013, which increased tensions in the region and elicited strong objections worldwide. In response, the United Nations Security Council unanimously passed resolutions that condemned North Korea for the nuclear tests and expanded sanctions against North Korea, most recently in March 2013;

• In December 2012, North Korea launched a satellite into orbit using a long-range rocket, despite concerns in the international community that such a launch would be in violation of the agreement with the United States as well as United Nations Security Council resolutions that prohibit North Korea from conducting launches that use ballistic missile technology; and

• In March 2010, a Korean naval vessel was destroyed by an underwater explosion, killing many of the crewmen on board. The Government formally accused North Korea of causing the sinking, while North Korea denied responsibility. Moreover, in November 2010, North Korea fired more than one hundred artillery shells that hit Korea’s Yeonpyeong Island near the Northern Limit Line, which acts as the de facto maritime boundary between Korea and North Korea on the west coast of the Korean peninsula, causing casualties and significant property damage. The Government condemned North Korea for the attack and vowed stern retaliation should there be further provocation.

North Korea’s economy also faces severe challenges. For example, in November 2009, the North Korean government redenominated its currency at a ratio of 100 to 1 as part of a currency reform undertaken in an attempt to control inflation and reduce income gaps. In tandem with the currency redenomination, the North Korean government banned the use or possession of foreign currency by its residents and closed down privately run markets, which led to severe inflation and food shortages. Such developments may further aggravate social and political tensions within North Korea.

There can be no assurance that the level of tension on the Korean peninsula will not escalate in the future. Any further increase in tensions, which may occur, for example, if North Korea experiences a leadership crisis, high level contacts between Korea and North Korea break down or military hostilities occur, could have a material adverse effect on our business, results of operations and financial condition.

Risks Relating to the Securities

If an investor surrenders his ADSs to withdraw the underlying shares, he may not be allowed to deposit the shares again to obtain ADSs.

Korean law currently limits foreign ownership of the ADSs and our shares. In addition, under our deposit agreement, the depositary bank cannot accept deposits of shares and deliver ADSs representing those shares unless (1) we have consented to such deposit or (2) Korean counsel has advised the depositary bank that the consent required under (1) is no longer required under Korean laws and regulations. Under current Korean laws and regulations, the depositary bank is required to obtain our prior consent for the number of shares to be deposited in any given proposed deposit which exceeds the difference between (1) the aggregate number of shares deposited by us or with our consent for the issuance of ADSs (including deposits in connection with the initial and all subsequent offerings of ADSs and stock dividends or other distributions related to these ADSs) and (2) the number of shares on deposit with the depositary bank at the time of such proposed deposit. The depositary bank has informed us that, at a time it considers to be appropriate, the depositary bank plans to start accepting deposits of shares without our consent and to deliver ADSs representing those shares up to the amount allowed under current Korean laws and regulations. Until such time, however, the depositary bank will continue to obtain our consent for such deposits of shares and delivery of ADSs, which we may not provide. Consequently, if an investor surrenders his ADSs to withdraw the underlying shares, he may not be allowed to deposit the shares again to obtain ADSs. See “Item 10. Additional Information—Item 10.D. Exchange Controls.”

A foreign investor may not be able to exercise voting rights with respect to common shares exceeding the number of common shares held by our largest domestic shareholder.

Under the Telecommunications Business Act, a foreign shareholder who holds 5.0% or more of our total shares is prohibited from becoming our largest shareholder. However, any foreign shareholder who held 5.0% or more of our total shares and was our largest shareholder on or prior to May 9, 2004 is exempt from the regulations, provided that such foreign shareholder may not acquire any more of our shares. Under the Telecommunications Business Act, the MSIP may, if it deems it necessary to preserve substantial public interests, prohibit a foreign shareholder from being our largest shareholder. In addition, the Foreign Investment Promotion Act prohibits any foreign shareholder from being our largest shareholder if such shareholder owns 5.0% or more of our shares with voting rights. In the event that any foreigner or foreign government acquires our shares in violation of the above provisions, such foreign shareholder may not be able to exercise voting rights with respect to common shares exceeding such threshold. The MSIP may also order us or the foreign shareholder to take corrective measures in respect of the excess shares within a specified period of six months or less.

Holders of ADSs will not be able to exercise appraisal rights unless they have withdrawn the underlying common stock and become our direct shareholders.

In some limited circumstances, including the transfer of the whole or any significant part of our business and our merger or consolidation with another company, dissenting shareholders have the right to require us to purchase their shares under Korean law. A holder of ADSs will not be able to exercise appraisal rights unless he has withdrawn the underlying common stock and become our direct shareholder. See “Item 10. Additional Information—Item 10.B. Memorandum and Articles of Association.”

An investor may not be able to exercise preemptive rights for additional shares and may suffer dilution of his equity interest in us.

The Commercial Code of Korea and our articles of incorporation require us, with some exceptions, to offer shareholders the right to subscribe for new shares in proportion to their existing

17

ownership percentage whenever new shares are issued. If we offer any rights to subscribe for additional shares of our common stock or any rights of any other nature, the depositary bank, after consultation with us, may make the rights available to an ADS holder or use reasonable efforts to dispose of the rights on behalf of the ADS holder and make the net proceeds available to the ADS holder. The depositary bank, however, is not required to make available to an ADS holder any rights to purchase any additional shares unless it deems that doing so is lawful and feasible and:

• a registration statement filed by us under the Securities Act of 1933, as amended, is in effect with respect to those shares; or

• the offering and sale of those shares is exempt from or is not subject to the registration requirements of the Securities Act.

We are under no obligation to file any registration statement. If a registration statement is required for an ADS holder to exercise preemptive rights but is not filed by us, the ADS holder will not be able to exercise his preemptive rights for additional shares. As a result, the ADS holder may suffer dilution of his equity interest in us.

Item 4.  Information on the Company

Item 4.A.  History and Development of the Company

In 1981, the Government established us under the Korea Telecom Act to operate the telecommunications services business that it previously directly operated. Under the Korea Telecom Act and the Government-Invested Enterprises Management Basic Act, the Government exercised substantial control over our business and affairs. Effective October 1, 1997, the Korea Telecom Act was repealed and the Government-Invested Enterprises Management Basic Act became inapplicable to us. As a result, we became a corporation under the Commercial Code, and our corporate organization and shareholders’ rights were governed by the Privatization Law and the Commercial Code. Among other things, we began to exercise greater autonomy in setting our annual budget and making investments in the telecommunications industry, and our shareholders began electing our directors, who had previously been appointed by the Government under the Korea Telecom Act.

18

Prior to 1993, the Government owned all of the issued shares of our common stock. From 1993 through May 2002, the Government disposed of all of its equity interest in us, and the Privatization Law ceased to apply to us in August 2002. We amended our legal name from Korea Telecom Corp. to KT Corporation in March 2002.

Before December 1991, we were the sole provider of local, domestic long-distance and international long-distance telephone services in Korea. The Government began to introduce competition in the telecommunications services market in the early 1990’s. As a result, including ourselves, there are currently three local telephone service providers, five domestic long-distance carriers and numerous international long-distance carriers (including voice resellers) in Korea. In addition, the Government awarded licenses to several service providers to promote competition in other telecommunications business areas such as mobile telephone services and data network services. On June 1, 2009, KTF, a subsidiary providing mobile telephone services, merged into KT Corporation, with KT Corporation surviving the merger, with the objective of maximizing management efficiencies of our fixed-line and mobile telecommunications operations as well as more effectively responding to the convergence trends in the telecommunications industry. See “Item 4.B. Business Overview—Competition.”

Our legal and commercial name is KT Corporation. Our principal executive offices are located at 206 Jungja-dong, Bundang-gu, Sungnam-si, Gyeonggi-do, Korea, and our telephone number is (8231) 727-0114.

Item 4.B.  Business Overview

We are the leading telecommunications service provider in Korea and one of the largest and most advanced in Asia. As an integrated telecommunications service provider, our principal services include:

• mobile telecommunications services;

• telephone services, including local, domestic long-distance and international long-distance fixed-line and VoIP telephone services and interconnection services to other telecommunications companies;

• broadband Internet access service and other Internet-related services, including IP-TV services;

• credit card and other financial services through KT Capital Co., Ltd. and BC Card Co., Ltd.;

• automobile rental services through KT Rental Co., Ltd.; and

• various other services, including leased line service and other data communication service, satellite service and information technology, real estate business, satellite TV service, media contents business and network services such as cloud computing services.

Leveraging on our dominant position in the fixed-line telephone services market and our established customer base in Korea, we have successfully pursued new growth opportunities during the past decade and obtained strong market positions in each of our principal lines of business. In particular:

• in the mobile services market in Korea, we achieved a market share of 30.8% with approximately 16.5 million subscribers as of December 31, 2012;

• in the fixed-line telephone services market in Korea, we continue to be the dominant provider with approximately 25.2 million installed lines, of which 15.1 million lines were in service as of December 31, 2012. As of such date, our market share of the local market was 82.8% and our market share of the domestic long-distance market was 79.2%;

19

• we are Korea’s largest broadband Internet access provider with 8.0 million subscribers as of December 31, 2012, representing a market share of 44.0%; and

• we are also the leading provider of data communication services in Korea.

For the year ended December 31, 2012, our operating revenues were ￦24,578 billion, our profit for the period was ￦1,111 billion and our basic earnings per share was ￦4,341. As of December 31, 2012, our total assets were ￦34,479 billion, total liabilities were ￦21,315 billion and total equity was ￦13,165 billion.

Business Strategy

We believe the telecommunications market in Korea is nearing saturation, despite certain areas of growth remaining due to Korea’s growing economy, consumers’ willingness to adopt new technologies, relatively high income and a relatively large middle class. To maintain our competitiveness, we believe we need to pursue growth in other areas, while maintaining our strength in existing businesses. In order to enhance the management efficiencies of our mobile and fixed-line telecommunications operations as well as more effectively respond to the convergence trends in the telecommunications industry, KTF merged into KT Corporation on June 1, 2009, with KT Corporation surviving the merger. In 2012, we restructured our organization into three business groups, the Telecommunication & Convergence Group, the Customer Group and the Global & Enterprise Group, so that we may achieve higher synergies, more effectively address differing needs of our customer segments, as well as strengthening our competitiveness.

We also established subsidiaries to oversee our media contents, satellite and real estate operations, and expanded the number of specialized employees for each business, to further strengthen such operations and to pursue strategic alliances with other global corporates. To seek further growth in a stagnant telecommunications market, we aim to become a global media distribution company, and utilizing our synergies, we intend to focus on developing the media contents, finance, security and automobile rental business and the expanding convergence market, as well as diversifying our portfolio into the advertising, education, health care and energy industries. Using our strong wired/wireless and clouding technologies, we also aim to contribute to a global market environment for active distribution of media contents, applications and solutions. Consistent with our overall goals, we aim to pursue the following strategy for our business groups:

• Telecommunication & Convergence Group. Through our Telecommunication & Convergence Group, we aim to expand our telecommunication and convergence operations by (i) improving our wired and wireless telecommunication market shares and average revenue per user, (ii) developing business strategies and plans specifically related to telecommunications and convergence, (iii) strengthening our competitiveness over products, customer service and other related services and (iv) developing and executing efficient marketing strategies. We also focus on expanding our wireless data communication business to meet the rising demand for broadband Internet access using advanced wireless data communications devices such as smartphones. We are working closely with handset manufacturers to expand our offerings of smartphones and handsets designed to promote convergence of fixed-line and mobile telecommunications services, as well as promote development of various applications for such devices.

In line with this strategy, we began offering Apple’s iPhone for the first time in Korea in November 2009 and have expanded our offerings of smartphones from other mobile handset manufacturers. We believe that our WiBro network, which enables two-way wireless broadband Internet access to portable computers, mobile phones and other

20

portable devices, as well as our extensive wireless LAN networks installed nationwide, enable our subscribers to maximize effective usage of their smartphones. We plan to take advantage of our industry-leading network infrastructure to attract more customers as this market further develops. In addition, we aim to further enhance our position in the mobile telecommunications market by leveraging on our strong brand, nationwide marketing network, competitive data usage rates, call centers dedicated to smartphone users, creative marketing strategies that address our potential customers’ needs and ability to bundle various mobile and fixed-line services. We also plan to further expand our contents and applications for smartphone users and mobile data users by cooperating with application developers in Korea and abroad, in order to further solidify our position as a leader in the convergence market.

In 2010, we launched a new brand “olleh” to promote our bundled products, which include broadband Internet access service, IP-TV service, Internet phone service and fixed-line telephone service. We aim to differentiate ourselves from our competitors by providing broadband Internet access service using high-speed fiber-to-the-home (or FTTH) connection and offering Internet phone service with value-added features such as video communication, short message service and phone banking. We also began offering real-time broadcasting service on our IP-TV service starting in November 2008.

We believe that convergence of fixed-line and mobile communications technologies provides a competitive advantage to us because we have the technological know-how and experience to design and construct a unified delivery platform for a new generation of value-added services. We plan to make such platform more readily available to others so that they may create additional contents and convenience solutions such as electronic commerce and digital transaction applications that can be utilized anywhere using various media and communications devices.

• Customer Group. Through our Customer Group, we aim to improve our marketing and customer service efforts for all of our products and services by (i) planning and executing strategy for each product that we offer and our marketing efforts, (ii) contributing to expanding our market share by strengthening our marketing and customer service efforts, and (iii) maximizing customer satisfaction by providing high quality customer service.

• Global & Enterprise Group. Through our Global & Enterprise Group, we aim to provide our corporate, small- and medium-sized enterprise and government agency customers with one-stop solution services, including designing data communications and information technology infrastructure and overseeing their day-to-day operations with the objective of achieving operational efficiencies and cost savings, as well as establishing and executing business plans for our global operations by (i) establishing active marketing strategy for expanding into the global market and (ii) entering into alliances and joint ventures with international corporates and agencies.

To that end, we provide solutions specifically tailored for individual clients, as well as Internet-based computing services, whereby shared resources, software and information are delivered from our data centers and servers. For example, we designed an urban transit infrastructure maintenance system for the Seoul Metropolitan Rapid Transit Corporation, in which workers are able to utilize their smartphones to report back their maintenance results to the headquarters remotely from the maintenance site. Leveraging our extensive customer base, we plan to further expand the range of innovative solutions for our enterprise customers.

The Telecommunications Industry in Korea

The Korean telecommunications industry is one of the most developed in Asia. According to the Korea Communications Commission, the number of mobile subscribers in Korea was 53.6 million and the number of broadband Internet access subscribers in Korea was 18.3 million as of December 31, 2012. As of December 31, 2012, the mobile penetration rate, which is calculated by dividing the number of mobile subscribers (including multiple counting of those who subscribe to more than one mobile service) by the population of Korea, was 105.3%, and the broadband Internet penetration rate, which is calculated by dividing the number of broadband Internet access service subscribers (including multiple counting of those who subscribe to more than one broadband Internet access service) by the number of households in Korea, was 103.6%.

Mobile Telecommunications Service Market

The Korean cellular market was formally established in 1984 when SK Telecom, formerly Korea Mobile Telecom, became the first mobile telephone operator in Korea. SK Telecom remained the only cellular operator in Korea until Shinsegi Telecom began service in 1994. In order to encourage further market growth and competition, the Government awarded three PCS licenses in June 1996. KTF was awarded a license alongside LG U+ and Hansol M.com, and commercial PCS service was launched in October 1997.

Since the introduction of three new operators in 1997, the Korean mobile market has undergone consolidation and significant growth. Following SK Telecom’s purchase of a controlling stake in Shinsegi, we acquired a 47.9% interest in Hansol M.com in 2000 and renamed the company KT M.com. KT M.com merged into KTF in May 2001 and Shinsegi merged into SK Telecom in January 2002. On June 1, 2009, KTF merged into KT Corporation, with KT Corporation surviving the merger. KT Corporation and SK Telecom offer third-generation, high-capacity HSDPA-based IMT-2000 wireless Internet and video multimedia communications services that use significantly greater bandwidth capacity. In July 2011, SK Telecom and LG U+ began offering fourth-generation communications services based on LTE technology, which enables data transmission at a speed faster than W-CDMA or WiBro networks, and we began our 4G LTE services in January 2012.

The table below gives the subscription and penetration information of the mobile telecommunications industry for the periods indicated:

	As of December 31,
	2008			2009			2010			2011			2012
Total Korean Population (1)		49,540			49,773			50,516			50,734			50,948
Mobile Subscribers (2)		45,607			47,944			50,767			52,507			53,624
Mobile Subscriber Growth Rate		4.9	%		5.1	%		5.9	%		3.4	%		2.1	%
Mobile Penetration (3)		92.1	%		96.3	%		100.5	%		103.5	%		105.3	%

(1) In thousands, based on the number of registered residents as published by the Ministry of Security and Public Administration of Korea.

(2) In thousands, based on information announced by the Korea Communications Commission.

(3) Penetration is determined by dividing mobile subscribers by total Korean population.

Broadband Internet Access Market

With the advancement of broadband technology, the Korean broadband Internet access market has experienced significant growth. The principal technologies used in providing high speed Internet access services are xDSL, HFC and fiber optic LAN. xDSL refers to various types of digital subscriber lines, including ADSL and VDSL. xDSL offers an access solution over existing telephone

22

lines using a specialized modem while HFC service involves the use of two-way cable networks. Fiber optic LAN is a technology that combines fiber optic cables and Unshielded Twisted Pair (or UTP) cables. Fiber optic cables are connected to residential and commercial buildings with UTP cable-based LAN capabilities. While xDSL and HFC are more widely used technologies because of their relative reliability, ease of provisioning and cost effectiveness, fiber optic LAN usage in Korea has been steadily increasing in recent years.

Since the subscribers of two-way cable networks share a limited bandwidth, the downstream speed tends to slow down as the number of subscribers increases, thereby decreasing the quality of HFC-based service. While xDSL technology was commercially introduced after HFC technology, it has surpassed HFC to become the prevalent broadband access platform in Korea. VDSL, ADSL-based technology with enhanced downstream speed, became commercialized in 2002. Some of the service providers have upgraded their broadband network to provide fiber optic LAN-based service to their subscribers, which further enhances data transmission speed up to 100 Mbps as well as improves connection quality, and enables such service providers to offer video-on-demand services with real-time high definition broadcasting.

In recent years, broadband Internet access service providers and mobile telecommunications service providers have focused their attention to provide wireless Internet connection capabilities. They have introduced wireless LAN service with speeds of up to 155 Mbps, which is designed to integrate fixed-line and wireless services by offering high speed wireless Internet access to laptops, PDAs and smartphones in hot-spot zones and at home. Some service providers have also developed wireless Internet networks to provide WiBro service, which enables two-way wireless broadband Internet access to portable computers, mobile phones and other portable devices at a speed averaging 3 Mbps.

Our Services

Mobile Service

We provide mobile services based on W-CDMA technology and LTE technology. Prior to the merger of KTF into KT Corporation, we provided such services through KTF, which was formerly a consolidated subsidiary. KTF obtained one of the three licenses to provide nationwide PCS service in June 1996 and began offering PCS service in October 1997. On June 1, 2009, KTF merged into KT Corporation, with KT Corporation surviving the merger, with the objective of maximizing management efficiencies of our fixed-line and mobile telecommunications operations as well as more effectively responding to the convergence trends in the telecommunications industry. We currently offer HSDPA-based IMT-2000 services, which are third-generation, high-capacity wireless Internet and video multimedia communications services based on W-CDMA wireless network standards. In January 2012, we also began offering 4G LTE services under the brand name “WARP,” following the termination of our 2G PCS services. We completed the expansion of our 4G LTE service coverage nationwide in October 2012.

23

Revenues related to mobile service accounted for 26.8% of our operating revenues in 2012. In addition, our goods sold, which are primarily from mobile handset sales, accounted for 18.7% of our operating revenues in 2012. The following table shows selected information concerning the usage of our network during the periods indicated and the number of our subscribers as of the end of such periods:

	As of or for the Year Ended December 31,
	2010		2011		2012
Outgoing Minutes (in millions)		34,570		36,102		34,520
Average Monthly Outgoing Minutes per Subscriber (1)		184		183		174
Average Monthly Revenue per Subscriber (2)	￦	36,801	￦	34,379	￦	33,519
Number of Subscribers (in thousands)		16,041		16,563		16,502

(1) The average monthly outgoing minutes per subscriber is computed by dividing the total minutes of usage for the period by the weighted average number of subscribers for the period and dividing the quotient by the number of months in the period. The weighted average number of subscribers is the sum of the total number of subscribers at the end of each month divided by the number of months in the period.

(2) The average monthly revenue per subscriber is computed by dividing initial activation fees, total monthly fees, usage charges, interconnection fees and value-added service fees for the period by the weighted average number of subscribers and dividing the quotient by the number of months in the period.

We compete with SK Telecom, a mobile service provider that has a longer operating history than us, and LG U+ that began its service at around the same time as KTF. As of December 31, 2012, we had approximately 16.5 million subscribers, or a market share of 30.8%, which was second largest among the three mobile service providers.

We market our mobile services primarily through independent exclusive dealers located throughout Korea. As of December 31, 2012, there were approximately 2,300 shops managed by our independent exclusive dealers. In addition to assisting new subscribers to activate mobile service and purchase handsets, authorized dealers are connected to our database and are able to assist customers with account information. Although most of these dealers sell exclusively our products and services, sub-dealers hired by exclusive dealers may sell products and services offered by other mobile telecommunications service providers. Authorized dealers are entitled to a commission for each new subscriber registered, as well as ongoing commissions for the first five years based primarily on the subscriber’s monthly fee, usage charges and length of subscription. The handsets sold by us to the dealers cannot be returned to us unless they are defective. If a handset is defective, it may be exchanged for a new one within 14 days from the date of purchase.

In response to the diversification of our customers’ demands and their increasing sophistication, we have also selectively engaged in opportunities to expand our internal sales channels in recent years. In 2007, we established a wholly-owned subsidiary, KT M&S Co., Ltd., that operates approximately 140 customer plazas that engage in mobile service sales activities as well as provide a one-stop shop for a wide range of other services and products that we offer. We also operate a website to promote and advertise our products and services to the general public and in particular to younger customers who are more familiar with the Internet.

We conduct the screening process for new subscribers with great caution. A potential subscriber must meet all minimum credit criteria before receiving mobile service. The procedure includes checking the history of non-payment and credit information from banks and credit agencies such as the National Information and Credit Evaluation Corporation. Applicants who do not meet the minimum criteria can only subscribe to the mobile service by using a pre-paid card.

24

Telephone Services

Fixed-line Telephone Services. We utilize our extensive nationwide telephone network to provide fixed-line telephone services, which consist of local, domestic long-distance, international long-distance services and land-to-mobile interconnection services. These fixed-line telephone services accounted for 13.7% of our operating revenues in 2012. Our telephone network includes exchanges, long-distance transmission equipment and fiber optic and copper cables. The following table gives some basic measures of the development of our telephone system.

	As of or for the Year Ended December 31,
	2008		2009		2010		2011		2012
Total Korean population (thousands) (1)		49,540		49,773		50,516		50,734		50,948
Lines installed (thousands) (2)		26,008		25,907		25,524		23,925		25,242
Lines in service (thousands) (2)		18,883		17,069		16,620		15,900		15,121
Lines in service per 100 inhabitants (3)		38.1		34.3		32.9		31.3		29.7
Fiber optic cable (kilometers)		312,232		405,528		448,328		527,188		584,932
Number of public telephones installed (thousands)		161		144		123		111		101
Domestic long-distance call minutes (millions) (4) (5)		11,591		9,526		7,318		6,574		6,067
Local call pulses (millions) (4)		12,449		8,406		7,973		6,697		6,071

(1) Based on the number of registered residents as published by the Ministry of Security and Public Administration of Korea.

(2) Including lines used for public telephones but excluding lines dedicated to centralized extension system services for corporate subscribers.

(3) Determined based on lines in service and total Korean population.

(4) Excluding calls placed from public telephones.

(5) Estimated by KT Corporation.

Our domestic long-distance cable network is entirely made up of fiber optic cable and can carry both voice and data transmissions. Compared to conventional materials such as coaxial cable, fiber optic cable provides significantly greater transmission capacity with less signal fading, thus requiring less frequent amplification. All of our lines are connected to exchanges capable of handling digital signal technology. A principal limitation of the older analog technology is that applications other than voice communications, such as the transmission of text and computer data, require either separate networks or conversion equipment. Digital systems permit a range of voice, text and data applications to be transmitted simultaneously on the same network.

The following table shows the number of minutes of international long-distance calls recorded by us and specific service providers utilizing our international long-distance network in each specified category for each year in the five-year period ended December 31, 2012.

	Year Ended December 31,
	2008		2009		2010		2011		2012
	(In millions of billed minutes)
Incoming international long-distance calls		603.7		442.2		523.5		541.6		520.3
Outgoing international long-distance calls		398.1		325.9		325.1		332.1		289.7
Total		1,001.8		768.1		848.7		873.6		810.0

Japan (20.7%), China (19.4%) and the United States (13.7%) accounted for the greatest percentage of our international long-distance call traffic measured in minutes in 2012. In recent years, the volume of our incoming calls has exceeded the volume of our outgoing calls. The agreed settlement rate is applied to the call minutes to determine the applicable net settlement payment.

Interconnection. Under the Telecommunications Business Act, we are required to permit other service providers to interconnect to our fixed-line network. Currently, the principal users of this

interconnection capacity include SK Broadband and LG U+ (offering local, domestic long-distance and international long-distance services), Onse and SK Telink (offering international and domestic long-distance services), and SK Telecom and LG U+ (transmitting calls to and from their mobile networks). Revenues from a landline user for a call initiated by a landline user to a mobile service subscriber (land-to-mobile interconnection) accounted for 2.7% of our operating revenues in 2012. We recognize as land-to-mobile interconnection revenue the entire amount of the usage charge collected from the landline user and recognize as an expense the amount of interconnection charge paid to the mobile service provider.

Internet phone services. The volume of calls made through Internet phone services has significantly increased since Internet phone service was first introduced in Korea in 1998. We provide Internet phone services that enable VoIP phone devices with broadband connection to make domestic and international calls. In order to differentiate our Internet phone services from our competitors’ services, we provide value-added services such as video communication, short message service, phone banking and a variety of traffic and local news information. As of December 31, 2012, we had approximately 3.3 million subscribers.

Internet Services

Broadband Internet Access Service. Leveraging on our nationwide network of 584,932 kilometers of fiber optic cable network, we have achieved a leading market position in the broadband Internet access market in Korea. We believe we have a competitive advantage over other broadband Internet access service providers because, unlike our competitors, we can utilize our existing networks nationwide to provide broadband Internet access service. Our broadband Internet access service accounted for 8.3% of our operating revenues in 2012. Our principal Internet access services include:

• ADSL, VDSL, Ethernet and FTTH services under the “olleh Internet” brand name;

• wireless LAN service (or WiFi) under the “ollehWiFi” brand name, which is designed to integrate fixed-line and wireless services by offering high speed wireless Internet access to laptops, PDAs and smartphones in hot-spot zones and olleh Internet service in fixed-line environments. OllehWiFi enables subscribers to access the Internet at up to 150 Mbps. We sponsored approximately 111,990 hot-spot zones nationwide for wireless connection as of December 31, 2012; and

• olleh 4G WiBro Internet access service, which enables two-way wireless broadband Internet access to portable computers, mobile phones and other portable devices at a speed averaging 5 Mbps per user.

We had 8.0 million fixed-line olleh Internet subscribers and approximately 183,000 ollehWiFi service subscribers as of December 31, 2012. We commercially launched our WiBro service in June 2006, and we had approximately 934,000 subscribers as of December 31, 2012. We also bundle our WiBro service with olleh Internet and ollehWiFi services at a discount in order to attract additional subscribers.

Our olleh Internet service utilizes ADSL technology, which is a technology that converts existing copper twisted-pair telephone lines into access paths for multimedia and high-speed data communications. ADSL transforms the existing public telephone network from one limited to voice, text and low-resolution graphics to a system capable of bringing multimedia to subscriber premises without new cabling. The asymmetric design optimizes the bandwidth by maximizing the downstream speed for downloading information from the Internet. While ADSL technology was commercially introduced

26

after HFC-based technology, it has surpassed HFC to become the prevalent access platform in Korea. VDSL, ADSL-based technology with enhanced downstream speed, became commercialized in July 2002. We are currently upgrading our broadband network to enable FTTH connection, which further enhances downstream speed up to 100 Mbps and connection quality. FTTH is a telecommunication architecture in which a communication path is provided over optical fiber cables extending from the telecommunications operator’s switching equipment to the boundary of home or office. FTTH uses fiber optic cable, which is able to carry a high-bandwidth signal for longer distances without degradation. FTTH enables us to deliver enhanced products and services that require high bandwidth, such as IP-TV service and delivery of other digital media content.

The high-speed downstream rates can reach up to 8 Mbps for ADSL and 100 Mbps for VDSL and FTTH. Downstream rates depend on a number of factors. For a constant wire gauge, the data rate decreases as the length of the copper wire increases. Generally, if the separation between the telephone office and the subscriber is greater than four kilometers, line attenuation is so severe that broadband speeds can no longer be achieved. Approximately 95% of the households subscribing to our basic local telephone service are located within a four kilometer radius of our telephone offices, making our olleh Internet service available to most of the Korean population. Fiber-optic cable used by FTTH, on the other hand, uses laser light to carry signals that travel long distances inside fiber optic cable without degradation.

Other Internet-related Services. Our other Internet-related services focus primarily on providing infrastructure and solutions for business enterprises, as well as IP-TV and network portal services. Our other Internet-related services accounted for 3.6% of our operating revenues in 2012.

We operate seven Internet data centers located throughout Korea and provide a wide range of computing services to companies which need servers, storages and leased lines. Internet data centers are facilities used to house, protect and maintain network server computers that store and deliver Internet and other network content, such as web pages, applications and data. Our Internet data centers are designed to meet international standards, and are equipped with temperature control systems, regulated and reliable power supplies, fire detection and suppression equipment, security monitoring and wide-bandwidth connections to the Internet. Internet data centers allow corporations to outsource their application and server hardware management.

Our Internet data centers offer network outsourcing services, server operation services and system support services. Our network outsourcing services include co-location, which is the installation of our customers’ network equipment at our Internet data centers. Co-location is designed to increase customers’ Internet connection speed and reduce connection time and costs by directly connecting the customers’ server to the Internet backbone switch at our Internet data centers. Our server operation services include optimal server management service and technical support service we provide with respect to the leased servers that are linked directly to our Internet backbone switch. We also lease servers and network equipment for a fixed monthly fee. Our system support services include providing system resources for a wide range of Internet computing services, such as application transfer, network storage, video streaming and application download, as well as sending short text messages and messages containing multimedia objects, such as images, audio and video.

We also offer a service called Bizmeka to develop and commercialize business-to-business solutions targeting small- and medium-sized business enterprises in Korea. Bizmeka is an applied application service provider which provides industry standard and specialized business solutions, including integrated business administration solutions and intranet collaboration solutions.

We also offer high definition video-on-demand and real-time broadcasting IP-TV services under the brand name “olleh TV.” Our IP-TV service offers access to an array of digital media contents,

27

including movies, sports, news, educational programs and TV replay, for a fixed monthly fee or on a pay-per-view basis. Through a digital set-top box that we rent to our customers, our customers are able to browse the catalog of digital media contents and view selected media streams on their television. A set-top box provides two-way communications on an IP network and decodes video streaming data. We expanded our IP-TV service to include real-time broadcasting in November 2008. We had 4.0 million olleh TV subscribers as of December 31, 2012.

Data Communication Service

Our data communication service involves offering exclusive lines that allow point-to-point connection for voice and data traffic between two or more geographically separate points. As of December 31, 2010, 2011 and 2012, we leased 303,009 lines, 276,147 lines and 229,062 lines to domestic and international businesses. The data communication service accounted for 5.3% of our operating revenues in 2012.

We provide dedicated and secure broadband Internet connection service to institutional customers under the “Kornet” brand name. We provide high-speed connection up to 10.0 Gbps connected to our internet backbone network with capacity of 6.6 Tbps, as well as rent to our customers and install necessary routers to ensure reliable Internet connection and enhanced security. We provide discount rates to qualified customers, including small- and medium-sized enterprises, businesses engaging in Internet access services and government agencies.

Financial Services

To further diversify our business and to create synergies through utilization of our mobile telecommunications network in financial services, we, through our subsidiary KT Capital Co., Ltd., acquired 1,622,520 additional shares of common stock of BC Card Co., Ltd. from Woori Bank for approximately ￦252 billion in October 2011. As we were deemed to have control over BC Card Co., Ltd., it became our consolidated subsidiary starting in October 2011. Our ownership interest in BC Card Co., Ltd. was 69.5% as of December 31, 2012. BC Card Co., Ltd. offers various credit card and related financial services. KT Capital had consolidated sales of ￦192 billion and net income of ￦11 billion for the year ended December 31, 2012 and consolidated assets of ￦2,084 billion and liabilities of ￦1,838 billion as of December 31, 2012. See Note 35 to the Consolidated Financial Statements. Financial Services accounted for 13.5% of our operating revenues in 2012.

Automobile Rental Services

We also operate KT Rental, a subsidiary that provides rental cars and equipment. In March 2010, MBK Partners, a private equity firm, and we jointly acquired Kumho Rent-A-Car Co., Ltd. from Korea Express Inc. for ￦263 billion, with each taking a 50% stake. Kumho Rent-A-Car was subsequently merged with the car rental business unit of KT Rental on June 1, 2010. KT Rental became a consolidated subsidiary starting in 2012, as the restriction on our controlling power over KT Rental pursuant to a shareholders’ agreement was resolved as a result of the acquisition of KT Rental’s common stock by Hana Daetoo Securities Co., Ltd. and other investors from the then-second largest shareholder in July 2012. KT Rental operated approximately 69,800 vehicles as of December 31, 2012 and has a market share of 22.3% of the domestic car rental market in 2012. See Note 35 to the Consolidated Financial Statements. Automobile rental services accounted for 1.0% of our operating revenues in 2012.

Miscellaneous Businesses

We also engage in various business activities that extend beyond telephone services and data communications services, including satellite services, information technology and network services, real estate development, satellite TV services, with the consolidation of KT Skylife Co. starting in

28

January 2011, and media contents business with the establishment of KT Media Hub Co., Ltd. in December 2012. Our miscellaneous businesses accounted for 9.1% of our operating revenues for 2012.

We provide transponder leasing, broadcasting, video distribution and data communications services through our satellites. We currently operate two satellites, Koreasat 5 and Koreasat 6 (also known as olleh 1), and own interests in two additional satellites, Koreasat 7 (also known as ABS-1) and Koreasat 8 (also known as ABS-2). In August 2006, we launched Koreasat 5. Koreasat 5, a combined civil and governmental communications satellite, is the first Korean satellite to provide commercial satellite services to neighboring countries, and the service coverage area includes Korea, Japan, Taiwan, the Philippines, the eastern part of China and the far-eastern part of Russia. The design life of Koreasat 5 is fifteen years.

We launched Koreasat 6 in December 2010, with a design life of fifteen years. Koreasat 6 began its commercial operation in February 2011 and carries transponders that are mainly used for direct-to-home satellite broadcasting, video distributions and data communications services. Most of the direct-to-home satellite broadcasting transponders are utilized by KT Skylife Co. We also lease satellite capacity from other satellite operators to offer satellite services to both domestic and international customers. In August 2010, we procured from Asia Broadcast Satellite four transponders on the ABS-1 satellite and an additional eight transponders on the ABS-2 satellite in order to provide global satellite services. ABS-1 began operation in September 2010, and ABS-2 is under construction and is expected to be launched during the third quarter of 2013.

In December 2012, we spun-off our satellite service business by establishing KT Sat Co., Ltd., in an effort to enhance operational specialization and to foster management efficiency, enabling us to respond more promptly to the changing market environments and increasing competitiveness. See Note 37 to the Consolidated Financial Statements.

We offer a broad array of integrated information technology and network services to our business customers. Our range of services include consulting, designing, building and maintaining systems and communication networks that satisfy the individual needs of our customers in the public and private sectors.

We own land and real estate in various locations nationwide. Technological developments have enhanced the coverage area of individual telecommunications facilities, which enable us to better utilize our existing land and other real estate holdings. In recent years, we have engaged in the planning and development of commercial and office buildings and condominiums on our unused sites, as well as in the leasing of buildings we own. We established KT Estate Inc. in August 2010 to oversee the planning, development and operation of our real estate assets, and established KT AMC, an asset management company, in September 2011 as a subsidiary of KT Estate Inc. to create additional synergies with our real estate assets. We made a contribution in-kind of ￦1,053 billion to KT Estate Inc. in December 2012 to further strengthen KT Estate’s competitiveness and to better utilize our assets.

To respond to the trend of convergence in the telecommunications and broadcasting industries, and to seek additional synergies with our existing operations, we acquired 5,600,000 shares of redeemable convertible preferred stock with voting rights and convertible bonds that were convertible into 5,600,000 shares of common stock of KT Skylife Co., Ltd. from Dutch Savings Holdings B.V. in January 2011 for approximately ￦246 billion. We exercised the conversion rights on the redeemable convertible preferred stock and the convertible bonds in March 2011, and owned a 50.2% interest in KT Skylife Co., Ltd. as of December 31, 2012. KT Skylife offers satellite TV services, which may also be packaged with our IP-TV services as further described below, and had consolidated sales of ￦575 billion and net income of ￦56 billion for the year ended December 31, 2012 and consolidated assets of ￦642 billion and liabilities of ￦293 billion as of December 31, 2012.

29

In December 2012, we also established KT Media Hub Co., Ltd., a subsidiary that specializes in the development of media contents, with a cash capital contribution of ￦80 billion. We believe that the media contents business will be a future growth opportunity for us, and this subsidiary further enhances our specialization in the media contents business. It also allows us to better adapt to the rapidly changing market environment in the field.

Fixed-line Telephone Services

Local Telephone Service. Our revenues from local telephone service consist primarily of:

• Service initiation fees for new lines;

• Monthly basic charges; and

• Monthly usage charges based on the number of call pulses.

The rates we charge for local calls are currently subject to approval by the MSIP after consultation with the Ministry of Strategy and Finance. The rates are identical for residential and commercial customers. All calls are currently measured by call pulses. Each pulse is determined by the duration of the call and the time of the day at which the call is made. Our current local usage rates, which have been in effect since May 2002, are ￦39 per pulse for regular service and ￦70 per pulse for public telephones. For local calls, a pulse is triggered at the beginning of each local call and every three minutes thereafter from 8:00 a.m. to 9:00 p.m. on weekdays and every 258 seconds thereafter on holidays and from 9:00 p.m. to 8:00 a.m. on weekdays.

32

We also charge a monthly basic charge ranging from ￦3,000 to ￦5,200, depending on location, and a non-refundable service initiation fee of ￦60,000 to new subscribers. The non-refundable service initiation fee is waived for the new subscribers who subscribe to our local service through our online application process. Until April 2001, we charged refundable service initiation deposits, which were refunded upon termination of service. As of December 31, 2012, we had ￦515 billion of refundable service initiation deposits outstanding and 2,345 thousand subscribers who are enrolled under the mandatory deposit plan and are eligible to switch to the no deposit plan and receive their service initiation deposit back (less the non-refundable service initial fees).

Domestic Long-distance Telephone Service. Our revenues from domestic long-distance service consist of charges for calls placed, charged for the duration, time of day and day of the week a call is placed, and the distance covered by the call. We are able to set our own rates for domestic long-distance service without approval from the MSIP.

Our current basic domestic long-distance rates, which have been in effect since November 2001, are ￦39 per three minutes for distances of up to 30 kilometers and ￦14.5 per ten seconds (equivalent to ￦261 per three minutes) for distances in excess of 30 kilometers. For domestic long-distance calls for distances of up to 30 kilometers, a pulse is triggered at the beginning of each call and every three minutes thereafter. For domestic long-distance calls for distances in excess of 30 kilometers, a pulse is triggered at the beginning of each call and every 10 seconds thereafter. Rates for domestic long-distance calls for distances up to 30 kilometers are currently discounted by an adjustment in the period between pulses, by approximately 11% (utilizing a pulse rate of 200 seconds) from 6:00 a.m. to midnight on holidays and from 6:00 a.m. to 8:00 a.m. on weekdays, and by approximately 43% (utilizing a pulse rate of 258 seconds) from midnight to 6:00 a.m. every day. Rates for domestic long-distance calls for distances in excess of 30 kilometers are currently discounted by approximately 10% (utilizing a rate of ￦13.1 per ten seconds) from 6:00 a.m. to midnight on holidays and from 6:00 a.m. to 8:00 a.m. on weekdays, and by approximately 30% (utilizing a rate of ￦10.2 per ten seconds) from midnight to 6:00 a.m. every day.

In recent years, we have begun to offer optional flat rate plans, discount plans and bundled product plans in order to mitigate the impact from lower usage of local and domestic long-distance calls and stabilize our revenues from fixed-line telephone services. For a discussion of our bundled products, see “—Bundled Products.” Some of our flat rate and discount plans that we currently offer include the following:

• A subscriber who elects to pay a monthly flat rate of ￦12,500 is able to make free local and domestic long-distance calls after 9 p.m. on weekdays or at any time on weekends. Each month, the subscriber also receives a free movie ticket and free 60 minutes of land-to-mobile calls. The subscriber is also eligible to receive a discount of up to 20%, subject to the length of the mandatory subscription period;

• A subscriber who elects to subscribe to our fixed-line phone service for a three year mandatory subscription period is able to make local and domestic long-distance calls at a flat rate of ￦39 per three minutes; and

• A subscriber who elects to subscribe to our broadband Internet access service or HSDPA-based mobile service for a three year mandatory subscription period is able to make local, domestic long-distance and land-to-mobile calls of up to ￦150,000 with a flat rate payment of ￦50,000 or such calls up to ￦50,000 with a flat rate payment of ￦10,000. Standard rates apply to calls that exceed the capped amounts.

33

International Long-distance Service. Our revenues from international long-distance service consist of:

• amounts we bill to customers for outgoing calls made to foreign countries (including customers who make calls to Korea from foreign countries under our home country direct-dial service);

• amounts we bill to foreign telecommunications carriers for connection to the Korean telephone network in respect of incoming calls (including calls placed in Korea by customers of the foreign carriers for home country direct-dial service); and

• other revenues, including revenues from international calls placed from public telephones.

We bill outgoing calls made by customers in Korea (and calls made to Korea from foreign countries under our home country direct-dial service) in accordance with our international long-distance rate schedule for the country called. These rates vary depending on the time of day at which a call is placed. We bill outgoing international calls on the basis of one-second increments. We are able to set our own rates for international long-distance service without approval from the MSIP.

For incoming calls (including calls placed in Korea by customers of the foreign carriers for home country direct-dial service), we receive settlement payments from the relevant foreign carrier at the applicable settlement rate specified under the agreement with the foreign carrier. We have entered into numerous bilateral agreements with foreign carriers. We negotiate the settlement rates under these agreements with each foreign carrier, subject to the MSIP’s approval. It is the practice among international carriers for the carrier in the country in which the call is billed to collect payments due in respect of the use of overseas networks. Although we record the gross amounts due to and from us in our financial statements, we make settlements with most carriers monthly or quarterly on a net basis.

Interconnection. We provide other telecommunications service providers, including mobile operators and other fixed-line operators, interconnection to our fixed-line network.

Land-to-mobile Interconnection. For a call initiated by a landline user to a mobile service subscriber, we collect from the landline user the land-to-mobile usage charge and remit to the mobile service provider a land-to-mobile interconnection charge. The MSIP periodically issues orders setting the interconnection charge calculation method applicable to interconnections with mobile service providers. The MSIP determines the land to mobile interconnection charge by calculating the long run incremental cost of mobile service providers, taking into consideration technology development and future expected costs.

The following table shows the interconnection charges we paid per minute (exclusive of value-added taxes) to mobile operators for landline to mobile calls.

In addition, we charge customers a one-time installation fee per line ranging from ￦56,000 to ￦1,940,000 depending on the capacity of the line.

Bundled Products

We utilize our extensive customer relationships and market knowledge to expand our revenue base by cross-selling our telecommunications products and services. In order to attract additional subscribers to our new services, we bundle our services, such as our broadband Internet access service with WiBro, IP-TV, Internet phone, fixed-line telephone service and mobile services, at a discount.

The following table summarizes our various basic bundled packages that we currently offer. The packages require subscribers to agree to a subscription period of three years.

	Monthly Rates
	Flat Rate		Mobile Monthly Fee

We believe that subscribers who sign up for bundled products are less likely to cancel our services than subscribers who subscribe to individual services. Subscription fees paid for our bundled products are allocated to each service in proportion to their fair value and the allocated amount is recognized as revenue according to the revenue recognition policy for each service.

Competition

Competition in the telecommunications sector in Korea is intense. In recent years, business combinations in the telecommunications industry have significantly changed the competitive landscape of the Korean telecommunications industry. In particular, SK Telecom acquired a controlling stake in Hanarotelecom Incorporated in 2008, which was renamed SK Broadband. The acquisition enabled SK Telecom to provide fixed-line telecommunications, broadband Internet access and IP-TV services together with its mobile telecommunications services. On January 1, 2010, LG Dacom and LG Powercom merged into LG Telecom Co., Ltd., which subsequently changed its name to LG U+. The merger enabled LG U+ provide a similar range of services as SK Telecom and us.

Under the Telecommunications Basic Law and the Telecommunications Business Law, telecommunications service providers in Korea are currently classified into network service providers, value-added service providers and specific service providers. See “—Regulation.”

37

Network Service Providers

All network service providers in Korea are permitted to set the rates for international or domestic long-distance services on their own without the MSIP’s approval. Many of our competitors have set their rates lower than ours. Currently, we can compete freely with other providers on the basis of rates in all services except for rates we charge for local calls, which require advance approval from the MSIP. In all service areas, we compete by endeavoring to provide superior customer service and superior technical quality, taking advantage of our broad customer base and our ability to provide various telecommunication services.

We and SK Telecom have been designated as market-dominating business entities in the local telephone service and cellular service markets, respectively, under the Telecommunications Business Act. Under this Act, a market-dominating business entity may not engage in any act of abuse, such as unreasonably interfering with business activities of other business entities, hindering unfairly the entry of newcomers or substantially restricting competition to the detriment of the interests of consumers. The Korea Communications Commission has also issued guidelines on fair competition of the telecommunications companies. If any telecommunications service provider breaches the guidelines, the Korea Communications Commission may take necessary corrective measures against it after a hearing at which the service provider may defend its action.

Mobile Service. Competition in the mobile telecommunications industry in Korea is intense among SK Telecom, LG U+ and us. Such competition has intensified in recent years due to the implementation of mobile number portability, which enabled mobile subscribers to switch their service provider while retaining the same mobile phone number, as well as payments of handset subsidies to purchasers of new handsets who agree to minimum subscription periods and the recent rollout of fourth-generation mobile services based on LTE technology by SK Telecom, LG U+ and us.

The following table shows the market shares in the mobile telecommunications market as of the dates indicated:

	Market Share (%)
	KT Corporation		SK Telecom		LG U+
December 31, 2010		31.6		50.6		17.8
December 31, 2011		31.5		50.6		17.9
December 31, 2012		30.8		50.3		18.9

We offer various rate plans, including those that offer a specified number of free airtime minutes per month in return for a higher monthly fee and those that are geared toward business customers. Our competitors also offer similar plans at competitive rates.

Local Telephone Service. We compete with SK Broadband and LG U+ in the local telephone service business. SK Broadband began providing local telephone service in 1999, followed by LG U+ in 2004. In addition, the services provided by mobile service providers have had a material adverse effect on us in terms of our revenues from fixed-line telephone services. We expect this trend to continue.

Although the local usage charge of our competitors and us is the same at ￦39 per pulse (generally three minutes), our competitors’ non-refundable telephone service initiation charges are lower than ours. Our customers pay a non-refundable telephone service initiation charge of ￦60,000 while customers of our competitors pay a non-refundable telephone service initiation charge of ￦30,000. Also, the basic monthly charge of our competitors is ￦4,500 compared to our basic charge of ￦5,200.

Domestic Long-distance Telephone Service. We compete with SK Broadband, LG U+, Onse and SK Telink in the domestic long-distance market. LG U+ began offering domestic long-distance service in 1996, followed by Onse in 1999 and SK Broadband and SK Telink in 2004. The following table shows the market shares in the domestic long-distance market as of the dates indicated:

Our competitors and we charge ￦39 per three minutes for domestic long-distance calls up to 30 kilometers. For domestic long-distance calls greater than 30 kilometers, our competitors typically charge between 3% to 5% less than us. The following table is a comparison of our standard long-distance usage charges per 10 seconds with the standard rates of our competitors as of December 31, 2012:

International Long-Distance Telephone Service. Four companies, SK Broadband, LG U+, Onse and SK Telink, directly compete with us in the international long-distance market. LG U+ began offering international long-distance service in 1991, followed by Onse in 1997 and SK Broadband in 2004. SK Telink, which only provides Internet phone service, entered the international long-distance market in 2003 and offers its services at rates lower than those for network-based international long-distance telephone services. The entry of Internet phone service providers and other telecommunications service providers, such as voice resellers, that can offer telecommunications services at rates lower than ours has increased competition in the international long-distance market and adversely affected our revenues and profitability from international long-distance services. See “—Specific Service Providers.”

Broadband Internet Access Service. The Korean broadband Internet access market has experienced significant growth in the past decade. SK Broadband entered the broadband market in 1999 offering both HFC and ADSL services, and we entered the market with our ADSL services in 1999, followed by Dreamline, Onse and LG U+. In addition, the entry of cable television providers that offer HFC-based broadband Internet access services at rates lower than ours has increased competition in the broadband Internet access market. We expect industry consolidation among our competitors in the near future, and smaller competitors in the broadband market today may become larger competitors.

The following table shows the market share in the broadband Internet access market as of the dates indicated:

	Market Share (%)
	KT Corporation		SK Broadband		LG U+		Others

(1) These are typical fees charged by cable providers.

Data Communication Service. We had a monopoly in domestic data communication service until 1994, when LG U+ was authorized to provide the leased-line service. The data communications service market has become more competitive with limited growth during the past decade, and we primarily compete with SK Broadband and LG U+.

Value-Added Service Providers

Value-added service providers may commence operations following filing of a report to the MSIP. The scope of business of a value-added service provider includes specific value-added telecommunications activities (other than services reserved for network service providers), such as data communications utilizing telecommunications facilities leased from network service providers.

40

Specific Service Providers

Specific service providers, such as Internet phone service providers and voice resellers, started operations in Korea in 1998. We began providing Internet phone service for international long-distance calls in May 1998. Our Internet phone service also competes with international long-distance services provided by voice resellers who have also seen sharp increases in demand for their services.

Regulation

With the establishment of the MSIP in March 2013, many of the regulatory responsibilities formerly handled by the Korea Communications Commission have been transferred to the MSIP. Under the Telecommunications Basic Law and the Telecommunications Business Law, the MSIP now has comprehensive regulatory authority over the telecommunications industry and all network service providers.

The MSIP has assumed primary policy and regulatory responsibility for matters such as: (i) licensing of network service providers (the MSIP authorizes the licensing of Internet Protocol Television (“IPTV”) service providers and, with the consent of the Korea Communications Commission, authorizes the licensing of satellite broadcasting companies); (ii) regulation of mergers and acquisitions, as well as license suspension and termination of network service providers; (iii) providing oversight on foreign ownership ratios in network service providers; and (iv) reviewing telecommunication matters as they relate to the public interest and approving ancillary telecommunication business activities. Additionally, the MSIP is responsible for a broad range of other policy and regulatory matters, including the administration and supervision of regulatory reporting by telecommunications companies, examination and analysis of accounting and business management practices in the industry, establishing and administering policies governing telecommunications service fees, value-added service providers and specific service providers, as well as supervising reporting requirements of standard telecommunications service/user contracts.

Under the revised supervisory framework, a network service provider must be licensed by the MSIP. Our license as a network service provider permits us to engage in a wide range of telecommunications services.

The Korea Communications Commission’s overall policy role is to play a key role in regulatory activities aimed at protecting service users in the broadcast and telecommunications market and it continues to be responsible for investigations and sanctions regarding violations by telecommunications companies, as well as for mediating disputes between service providers and users. The Korea Communications Commission is established under the direct jurisdiction of the President and is comprised of five standing commissioners. Commissioners of the Korea Communications Commission are appointed by the President, and the appointment of the Chairperson must be approved at a confirmation hearing at the National Assembly.

Under the Use and Protection of Credit Information Act, telecommunications service providers are also required to disclose personal credit information of their customers only for the purpose of validating and maintaining telecommunications service agreements. Korean telecommunications service providers may use their customers’ credit information only to the extent allowed by the Use and Protection of Credit Information Act, which has gained greater importance in recent years due to the occurrence of personal information leakage incidents.

The MSIP also has the authority to regulate the IP media market, including IP-TV services. We began offering IP-TV services with real-time high definition broadcasting on November 17, 2008. Under

41

the Internet Multimedia Broadcasting Business Act, anyone intending to engage in the IP media broadcasting business must obtain a license from the MSIP. The ownership of the shares of an IP media broadcasting company by a newspaper, a news agency or a foreigner is limited.

Rates

Under current regulations implementing the Telecommunications Business Act, a network service provider may set its rates at its discretion, although it must report to the MSIP the rates and the general terms and conditions for each type of network service provided by it. There is, however, one exception to this general rule: if a network service provider has the largest market share for a specified type of service and its revenue from that service for the previous year exceeds a specific revenue amount set by the MSIP, it must obtain prior approval from the MSIP for the rates and the general terms for that service. Each year the MSIP designates the service providers and the types of services for which the rates and the general terms must be approved by the MSIP. In 2011, the Korea Communications Commission designated us for local telephone service and SK Telecom for mobile service, which currently remains in effect. The MSIP, in consultation with the Ministry of Strategy and Finance, is required to approve the rates proposed by a network service provider if (1) the proposed rates are appropriate, fair and reasonable and (2) the calculation method for the rates are appropriate and transparent.

Other Activities

A network service provider, such as us, must obtain the permission of the MSIP in order to:

• engage in certain businesses specified in the Presidential Decree under the Telecommunications Business Act, such as the telecommunications equipment manufacturing business and the telecommunications network construction business;

• change the conditions for its licenses;

• transfer, terminate, suspend or spin off all or a part of the business for which it is licensed;

• acquire all or a part of the business of another network service provider; or

• enter into a merger with another network service provider.

A telephone service provider may provide some network services using the equipment it currently has by submitting a report to the MSIP. The MSIP can revoke our licenses or order the suspension of any of our businesses if we do not comply with the regulations of the MSIP under the Telecommunications Business Law.

In July 2011, the Korea Communications Commission issued a guideline that limits the marketing expenditure amounts of telecommunication service providers in Korea to 20% of their revenues, with the restrictions applicable to fixed-line and mobile segments to be calculated separately. However, up to ￦150 billion of the marketing expenditures may be applied to either segment at the discretion of the service provider. The calculation of marketing expenditure amounts under the guideline excludes advertising expenses and the calculation of revenue amounts excludes revenues from handset sales. The MSIP may periodically adjust the guideline to accommodate changes in market conditions.

The responsibilities of the MSIP include:

• drafting and implementing plans for developing telecommunications technology;

42

• fostering and providing guidance to institutions and entities that conduct research relating to telecommunications; and

• recommending to network service providers that they invest in research and development or that they contribute to telecommunications research institutes in Korea.

In addition, all network service providers (other than regional paging service providers) are obligated to contribute toward the supply of “universal” telecommunications services in Korea. Telecommunications service providers designated as “universal service providers” by the MSIP are required to provide universal telecommunications services such as local services, local public telephone services, discount services for persons with disabilities and for certain low-income persons, telecommunications services for remote islands and wireless communication services for ships. We have been designated as a universal service provider. The costs and losses recognized by universal service providers in connection with providing these universal telecommunications services will be shared on an annual basis by all network service providers (other than regional paging service providers), including us, on a pro rata basis based on their respective net annual revenue calculated pursuant to a formula set by the MSIP.

A network service provider must permit other network service providers to co-use wirelines connecting the switching equipment to end-users, upon the request of such other network service providers. In addition, a network service provider may permit other network service providers to co-use its wireless communication systems upon the request of any of such other network service providers. The compensation method for the co-use must be determined by the MSIP and be settled, by fair and proper methods.

In addition, we are required to lease to other companies our fixed-lines that connect subscribers to our network. This system, which is called local loop unbundling, is intended to prevent excessive investment in local loops. This system requires us to lease the portion of our copper lines that represent our excess capacity to other companies upon their request at rates that are determined by the MSIP based on our cost, and taking into consideration an appropriate rate of return, to enable them to provide voice and broadband services. Revenues from local loop unbundling are recognized as revenues from miscellaneous businesses.

Foreign Investment

The Telecommunications Business Act restricts the ownership and control of network service providers by foreign shareholders. Foreigners, foreign governments and “foreign invested companies” may not own more than 49.0% of the issued shares with voting rights of a network service provider, including us, and a foreign shareholder may not become our largest shareholder if such shareholder holds 5.0% or more of our shares. For purposes of the Telecommunications Business Act, the term “foreign invested company” means a company in which foreigners and foreign governments hold 15.0% or more shares with voting rights in the aggregate and a foreigner or a foreign government is the largest shareholder, provided, however, that such company will not be counted as a foreign shareholder for the purposes of the above-referenced 49.0% limit if it holds less than 1.0% of our total issued and outstanding shares with voting rights. As of December 31, 2012, 47.6% of our common shares were owned by foreign investors. In the event that a network service provider violates the shareholding restrictions, its foreign shareholders cannot exercise voting rights for their shares in excess of such limitation, and the MSIP may require corrective measures be taken to comply with the ownership restrictions. There is no restriction on foreign ownership for specific service providers and value-added service providers.

43

Individual Shareholding Limit

Under the Telecommunications Business Act, a foreign shareholder who holds 5.0% or more of our total shares is prohibited from becoming our largest shareholder. However, any foreign shareholder who held 5.0% or more of our total shares and was our largest shareholder on or prior to May 9, 2004 is exempt from the regulations, provided that such foreign shareholder may not acquire any more of our shares. In addition, under the Telecommunications Business Act, the MSIP may, if it deems it necessary to preserve substantial public interests, prohibit a foreign shareholder from being our largest shareholder. In addition, the Foreign Investment Promotion Act prohibits any foreign shareholder from being our largest shareholder, if such shareholder owns 5.0% or more of our shares with voting rights. In the event that any foreigner or foreign government acquires our shares in violation of the above provisions, the Telecommunications Business Act restricts such foreign shareholder from exercising his or her voting rights with respect to common shares exceeding such threshold. The MSIP may also order us or the foreign shareholder to take corrective measures in respect of the excess shares within a specified period of six months or less.

Customers and Customer Billing

We typically charge residential subscribers and business subscribers similar rates for services provided. On a case-by-case basis, we also provide discount rates for some of our high-volume business subscribers. We bill all of our customers on a monthly basis. Our customers may make payment at either payment points such as local post offices, banks or our service offices, through a direct-debit service that automatically deducts the monthly payment from a subscriber’s designated bank account, or through a direct-charge service that automatically charges the monthly payment to a subscriber’s designated credit card account. Approximately 70% of our subscribers as of December 31, 2012 pay through the direct-debit service. Accounts of subscribers who fail to pay our invoice are transferred to a collection agency, which sends out a notice of payment. If such charges are not paid after notice, we cease to provide outgoing service to such subscribers after a period of time determined by the type of subscribed service. If charges are still not paid two to three months after outgoing service is cut off, we cease all services to such subscribers. After service is ceased, the overdue charges that are not collected by the collection agency are written off.

Insurance

We carry insurance against loss or damage to all significant buildings and automobiles. Except for our insurance coverage of our satellites and Internet data centers, we do not carry insurance covering losses to outside plants or to equipment because we believe the cost of such insurance is excessive and the risk of material loss or damage is insignificant. We do not have any provisions or reserves against such loss or damage. We do not carry any business interruption insurance.

We provide co-location and a variety of value-added services including server-hosting services to a number of corporations whose business largely depends on critical data operated on our servers or on their servers located at our data centers. Any disruptions, interruptions, physical or electronic data loss, delays or slow down in communication connections could expose us to potential liabilities for losses relating to the disrupted businesses of our customers relying on our services.

Information Technology and Operational Systems

Enhancement of our information technology and operational systems and efficient utilization of such systems are important in effectively promoting our core strategies. We are committed to continually investing in and enhancing our information technology systems, which provide support to many aspects of our businesses. In order to respond more effectively to a changing business environment, we are currently pursuing major upgrades to our company-wide business information

44

technology and operational systems, and as the first stage of such upgrades, a new enterprise resource planning system (the “New ERP System”) was completed and implemented during the second half of 2012. The New ERP System has contributed to enhancing various aspects of our internal processes and control systems, and we are establishing various plans to effectively utilize the New ERP System and to stabilize our internal control processes in connection with the New ERP System. We also expect to gradually implement other upgrades to our information technology and operational systems in the near future, including the implementation of a new billing system scheduled in the second half of 2013.

Item 4.C.  Organizational Structure

These matters are discussed under Item 4.B. where relevant.

Item 4.D.  Property, Plants and Equipment

Our principal fixed asset is our integrated telecommunications networks. In addition, we own buildings and real estate throughout Korea.

Our fixed-line equipment vendors and mobile equipment suppliers include well-known international and local suppliers such as Samsung Electronics, LG Electronics, Cisco Systems and Apple Inc.

Mobile Networks

Our mobile network architecture includes the following components:

• cell sites, which are physical locations equipped with base transceiver stations consisting of transmitters, receivers and other equipment used to communicate through radio channels with subscribers’ mobile telephone handsets within the range of a cell;

• base station controllers, which connect to and control, the base transceiver stations;

• mobile switching centers, which in turn control the base station controllers and the routing of telephone calls; and

• transmission lines, which connect the mobile switching centers, base station controllers, base transceiver stations and the public switched telephone network.

The following table lists selected information regarding our mobile networks as of December 31, 2012:

	W-CDMA		LTE
Mobile switching centers		86		10
Base station controllers		692		—
Base transceiver stations		4,937		11,765
Indoor and outdoor repeaters		273,155		89,261

We have a license to use 40 MHz of bandwidth in the 2.1 GHz spectrum that we use to provide IMT-2000 services based on W-CDMA wireless network standards. Such license expires in December 2016, and we are required to pay approximately ￦1.3 trillion for use of such bandwidth during the license period of 15 years. In April 2010, the Korea Communications Commission announced its decision to allocate 20 MHz of bandwidth in the 900 MHz spectrum to us, which became effective in

45

July 2011, for which we are required to pay a portion of the actual sales generated from using the bandwidth in the 900 MHz spectrum during the license period of 10 years as a usage fee for the bandwidth, as well as a portion of expected sales that was determined by the Korea Communications Commission at the time of allocation. In June 2011, our right to use 40 MHz of bandwidth in the 1.8 GHz spectrum expired, and the Korea Communications Commission allocated back to us the right to use 20 MHz of such bandwidth in the 1.8 GHz spectrum upon expiration pursuant to our application, for which we are required to pay a portion of the actual sales generated from using the bandwidth in the 1.8 GHz spectrum during the license period of 10 years as a usage fee for the bandwidth, as well as a portion of expected sales that was determined by the Korea Communications Commission at the time of allocation

In August 2011, the Korea Communications Commission auctioned the right to use the remaining 20 MHz of bandwidth in the 1.8 GHz spectrum that we relinquished, 10 MHz of additional bandwidth in the 800 MHz spectrum and 20 MHz of additional bandwidth in the 2.1 GHz spectrum. We acquired the right to use the 10 MHz of bandwidth in the 800 MHz spectrum, for which we are required to pay a total usage fee of ￦261 billion during the license period of 10 years, SK Telecom acquired the right to use the 20 MHz of bandwidth in the 1.8 GHz spectrum and LG U+ acquired the right to use the 20 MHz bandwidth in the 2.1 GHz spectrum. We began using the 20 MHz of bandwidth in the 1.8 GHz spectrum, which became available upon termination of our 2G PCS services, to provide our 4G LTE services starting in January 2012, and expect to utilize the newly allocated bandwidths in the 800 MHz and 900 MHz spectrums to further expand our 4G LTE services in the future, if necessary. The Korea Communications Commission announced in December 2012 that it will further auction 60 MHz of bandwidth in the 1.8 GHz spectrum, which had been used by governmental entities such as the military, and 80 MHz of bandwidth in the 2.6 GHz spectrum, which had been used for digital multimedia broadcasting services. The auction is expected to take place in June 2013.

Furthermore, in anticipation of a significant increase in data transmission traffic in the near future due to the changing mobile usage environment, we are seeking to maximize the utilization of our W-CDMA, Wibro and WiFi networks to provide better internet access for our customers, as well as applying our Cloud Communication Center technology to our 4G LTE services during 2012. Cloud Communications Center technology, which we applied to our 3G networks in Seoul and other metropolitan areas during 2011, allows faster and more stable access to the internet by dissipating heavy data traffic through utilization of virtual communication centers. We have also installed an intelligent network on our mobile network infrastructure to provide a wide range of advanced call features and value-added services.

Exchanges

Exchanges include local exchanges and “toll” exchanges that connect local exchanges to long-distance transmission facilities. We had 25.0 million lines connected to local exchanges and 2.1 million lines connected to toll exchanges as of December 31, 2012.

All of our exchanges are fully automatic. We completed replacement of all electromechanical analog exchanges with digital exchanges in June 2003 in order to provide higher speed and larger volume services. Starting in 2006, we also began conversion of our exchanges to be compatible to Internet protocol platform in preparation for building our next generation broadband convergence network by 2021. As of December 31, 2012, approximately 85% of our lines connected to toll exchanges are compatible to Internet protocol platform.

Internet Backbone

Our Internet backbone network, called KORNET, has the capacity to handle aggregate traffic of our broadband Internet access subscribers, Internet data centers and Internet exchange system at

46

any given moment of up to 6.6 Tbps as of December 31, 2012. We have set up contingent plans to prepare against various incidents that could affect reliable Internet access service. Starting in 2005, we have also begun deploying our Internet protocol premium network that enables us to more reliably support olleh TV, WiBro, Internet Phone, upgraded VoIP services and other Internet protocol services. As of December 31, 2012, our Internet protocol premium network had 1,032 lines installed to provide voice over Internet protocol services and a total capacity to handle up to 1.4 Tbps of IP-TV, voice and WiBro service traffic.

Access Lines

As of December 31, 2012, we had 15.1 million access lines installed, which allow us to reach virtually all homes and businesses in Korea. As part of our broadband deployment strategy, we have upgraded many of our access lines by equipping them with broadband capability using xDSL and FTTH technology. As of December 31, 2012, we had approximately 13.8 million broadband lines with speeds of at least 50 Mbps that enable us to deliver broadband Internet access and multimedia content to our customers.

Transmission Network

Our domestic fiber optic cable network consisted of 584,932 kilometers of fiber optic cables as of December 31, 2012 of which 111,120 kilometers of fiber optic cables are used to connect our backbone network and 473,812 kilometers are used to connect the backbone network to our subscribers. Our backbone network utilizes dense wavelength division multiplexing technology for connecting major cities as well as optical add-drop multiplexer technology for connecting neighboring cities. Dense wavelength division multiplexing technology improves bandwidth efficiency by enabling transmission of data from multiple signals across one fiber strand in a cable by carrying each signal on a separate wavelength. We enhanced our backbone network connecting six major cities in Korea by implementing an optical cross-connector (OXC) architecture in 2008 and are in the process of building our next generation broadband convergence network through installation of network equipment utilizing optical reconfigurable add-drop multiplexer technology and multi-service provisioning platform.

Our extensive domestic long-distance network is supplemented by our fully digital domestic microwave network, which consisted of 55 relay sites as of December 31, 2012.

International Network

Our international network infrastructure consists of both submarine cables and satellite transmission systems, including two submarine cable-landing stations in Busan and Keoje and two satellite teleports in Kumsan and Boeun. Data services such as international private lease circuits, Internet protocol and very small aperture terminals are provided through submarine cables and satellite transmission. In order to guarantee high quality services to our end customers, our submarine cables and satellite transmission systems are linked to various points-of-presence in the United States, Asia and Europe. In addition, our international telecommunications networks are directly linked to approximately 240 telecommunications service providers in various international destinations and are routed through our three international switching centers in Seoul, Daejeon and Busan.

Our international Internet backbone with capacity of 390 Gbps is connected to approximately 180 Internet service providers through our two Internet gateways in Heawha and Guro. In addition, we operate a video backbone with capacity of one Gbps to transmit video signals from Korea to the rest of the world.

47

Satellites

In order to provide broadcasting, video distribution and broadband data services in select areas, we operate two satellites, Koreasat 5 and 6, launched in 2006 and 2010, respectively, and own certain of the transponders in two additional satellites, ABS-1 launched in 2010 and ABS-2 expected to be launched in the second half of 2013. See “Item 4.B. Business Overview—Our Services—Satellite Services.”

International Submarine Cable Networks

International traffic is handled by telecommunications satellites and submarine cables. Because of the high cost of laying a submarine cable, the usual practice is for multiple carriers to jointly commission a new cable and share the costs and the capacity. We own interests in several international fiber optic submarine cable networks, including:

• a 1.4% interest in the 29,000-kilometer FLAG Europe-Asia network connecting Korea, Southeast Asia, the Middle East and Europe, activated since April 1997;

• a 1.8% interest in the 39,000-kilometer Southeast Asia-Middle East-Western Europe 3 Cable Network linking 34 countries, activated since December 1999;

• a 6.7% interest in the 30,444-kilometer China-U.S. Cable Network linking Korea, China, Japan, Taiwan and the United States, activated since January 2000;

• a 5.1% interest in the 19,000-kilometer Asia Pacific Cable Network 2 connecting Korea, China, Japan, Taiwan, Hong Kong, Philippines, Singapore and Malaysia, activated since December 2001;

• a 20.0% interest in the 500-kilometer Korea-Japan Cable Network linking Korea and Japan, activated since March 2002; and

• a 13.1% interest in the 16,500-kilometer Trans Pacific Express Cable Network linking Korea, China, Taiwan and the United States, activated since September 2008.

We have also invested in eight other international fiber optic submarine cables around the world.

Item 4A.  Unresolved Staff Comments

We do not have any unresolved comments from the Securities and Exchange Commission staff regarding our periodic reports under the Exchange Act of 1934.

Item 5.  Operating and Financial Review and Prospects

Item 5.A.  Operating Results

The following discussion and analysis is based on our consolidated financial statements, which have been prepared in accordance with IFRS as issued by the IASB.

Overview

We are an integrated provider of telecommunications services. Our principal services include mobile service, fixed-line telephone services, Internet services including broadband Internet access service and data communication service. The principal factors affecting our revenues from these services have been our rates for, and the usage volume of, these services, as well as the number of subscribers. For information on rates we charge for our services, see “Item 4. Information on the Company—Item 4.B. Business Overview—Revenues and Rates.” In 2012, we determined our

48

operating segments for financial reporting purposes as (i) the Telecommunication & Convergence Customer Group, which engages in providing various telecommunication services to individual/home customers and the convergence business, (ii) the Global & Enterprise Customer Group, which engages in telecommunication services for the global market and corporate customers, as well as data communication service, (iii) the Finance/Rental Business Group, which engages in providing various financial services such as credit card and lending, as well as automobile rental and leasing business and (iv) others, which include security services, satellite service, information technology and network services, satellite TV service and real estate development businesses. However, due to the foregoing restructuring of the segment, along with the implementation of the New ERP System and the resulting limitation on the availability of necessary financial information, we are able to provide only operating revenue information by segment for 2010 and not the full segment information.

One of the major factors contributing to our historical performance was the growth of the Korean economy, and our future performance will depend at least in part on Korea’s general economic growth and prospects. For a description of recent developments that have had and may continue to have an adverse effect on our results of operations and financial condition, see “Item 3. Key Information—Item 3.D. Risk Factors—Korea is our most important market, and our current business and future growth could be materially and adversely affected if economic conditions in Korea deteriorate.” A number of other developments have had or are expected to have a material impact on our results of operations, financial condition and capital expenditures. These developments include:

• acquisitions and disposals of interests in subsidiaries and joint ventures;

• usage fees for bandwidths;

• changes in the rate structure for our services; and

• researching and implementing technology upgrades and additional telecommunication services.

As a result of these factors, our financial results in the past may not be indicative of future results or trends in those results.

Acquisitions and Disposals of Interests in Subsidiaries and Joint Ventures

One key aspect of our overall business strategy calls for acquisitions of businesses and entering into joint ventures that complement or diversify our current business, as well as disposal or termination of such businesses from time to time. The following summarizes our recent acquisitions and disposals:

• in January 2011, we acquired 5,600,000 shares of redeemable convertible preferred stock with voting rights and convertible bonds that were convertible into 5,600,000 shares of common stock of KT Skylife Co., Ltd. from Dutch Savings Holdings B.V. in January 2011 for approximately ￦246 billion, to respond to the trend of convergence in the telecommunications and broadcasting industries, and to seek additional synergies with our existing operations. We exercised the conversion rights on the redeemable convertible preferred stock and the convertible bonds in March 2011, and owned a 50.2% interest in KT Skylife Co., Ltd. as of December 31, 2012;

• in June and October 2011, we sold a total of 5,309,189 common shares of New Telephone Company, Inc., representing all of our interests in New Telephone Company, Inc., for approximately ￦380 billion. Located in Russia, New Telephone Company, Inc. had

49

previously been our consolidated subsidiary providing fixed-line telephone services in Vladivostok, and our decision to dispose of our interest in that company was in part affected by the changing landscape in the Russian telecommunications market, where telecommunications service providers were becoming more nationalized and increasing rapidly in size as a result;

• in October 2011, we, through our subsidiary KT Capital Co., Ltd., acquired an additional 1,622,520 common shares of BC Card Co., Ltd. from Woori Bank for approximately ￦252 billion, to further diversify our business and to create synergies through utilization of our mobile telecommunications network in financial services, thereby increasing our ownership interest in BC Card Co., Ltd. to 38.86%, making it our consolidated subsidiary as a result of deemed control starting in October 2011;

• Starting in July 2012, KT Rental Co., Ltd., our 58.0% owned subsidiary, became our consolidated subsidiary as a result of the acquisition of KT Rental’s common stock by Hana Daetoo Securities Co., Ltd. and other investors from the then-second largest shareholder in July 2012, and the restriction on our control over KT Rental pursuant to a shareholders’ agreement being resolved as a result; and

• In December 2012, we submitted a non-binding bid for Vivendi SA’s 53.0% controlling stake in Maroc Telecom SA, a telecommunications service provider based in Rabat, Morocco. While we announced our decision in March 2013 not to submit a formal bid for Maroc Telecom SA, we may consider various investment options with Maroc Telecom SA.

Our financial condition and results of operations may be affected as a result of such acquisitions, disposals or consolidation. Furthermore, pursuing acquisitions or joint venture transactions also requires significant capital, and as we pursue further growth opportunities for the future, we may need to raise additional capital by incurring loans or through the issuances of bonds or other securities in the international capital markets, which may lead to increased levels of debt and debt servicing costs in the future.

Bandwidth Usage Fees

One of the principal limitations on a wireless network’s subscriber capacity is the amount of bandwidth spectrum allocated to the service provider. The growth of our mobile telecommunications business and the increase in usage of wireless data transmission services have been significant factors in the increased utilization of our bandwidth, since wireless data applications are generally more bandwidth-intensive than voice services. The current trend of increasing data transmission use and the increasing sophistication of multimedia content is likely to put additional strain on the bandwidth capacity of mobile service providers. We have acquired various licenses in recent years to secure additional bandwidth capacity to provide our broad range of services, for which we typically pay a portion of the actual sales generated from using the bandwidth during the license period as a usage fee, as well as a portion of expected sales as determined by the Korea Communications Commission at the time of allocation. The Korea Communications Commission announced in December 2012 that it will further auction 60 MHz of bandwidth in the 1.8 GHz spectrum, which had been used by governmental entities such as the military, and 80 MHz of bandwidth in the 2.6 GHz spectrum, which had been used for digital multimedia broadcasting services. The auction is expected to take place in June 2013. For a description of our licenses, see “Item 4.D.—Property, Plants and Equipment—Mobile Networks.” In order to continue to maintain sufficient bandwidth capacity, we will require additional capital to renew existing bandwidth spectrum or receive additional bandwidth allocation, or cost-effectively implement technologies that enhance bandwidth usage efficiency.

50

Changes in the Rate Structure for Our Services

Periodically, we adjust our rate structure for our services. In order to mitigate the impact from lower usage charges of local and domestic long-distance calls, we have increased our basic monthly charges and offer various optional flat rate plans for our fixed-line subscribers. Such adjustments in the rate structure have increased the portion of fixed income and stabilized our cash flow. In addition, because the growing use of mobile telecommunications services has decreased the usage of our fixed-line telephone services, we believe we are able to maximize our revenues from fixed-line telephone services by adjusting the rate structure so as to increase our basic monthly charges. We also provide bundled packages of our various services at a discount in order to attract additional subscribers to our new services. We currently bundle our broadband Internet access service with WiBro, IP-TV, fixed-line telephone service, internet phone services and mobile services at a discount.

The MSIP, in consultation with the Ministry of Strategy and Finance, currently approves rates charged by us for local telephone service. In addition, the MSIP currently does not regulate our domestic long-distance, international long-distance, broadband internet access and mobile service rates, but it periodically announces public policy guidelines or suggestions on tariffs for non-regulated services, which we have followed in the past. For a discussion of adjustments in our rate structure, see “Item 4. Information on the Company—Item 4.B. Business Overview—Revenues and Rates.”

Researching and Implementing Technology Upgrades and Additional Telecommunication Services

The telecommunications industry is characterized by continual advances and improvements in telecommunications technology, and we have been continually researching and implementing technology upgrades and additional telecommunication services to maintain our competitiveness. For example, we are currently upgrading our broadband network to enable FTTH connection, which enhances downstream speed and connection quality. FTTH is a telecommunication architecture in which a communication path is provided over optical fiber cables extending from the telecommunications operator’s switching equipment to the boundary of home or office. FTTH uses fiber optic cable, which is able to carry a high-bandwidth signal for longer distances without degradation. FTTH enables us to deliver enhanced products and services that require high bandwidth, such as IP-TV service and delivery of other digital media content. In addition, we have been building more advanced mobile telecommunications networks based on LTE technology, which is generally referred to as a 4G technology, and commenced providing commercial 4G LTE services in the Seoul metropolitan area on January 3, 2012. We completed the expansion of our 4G LTE service coverage nationwide in October 2012. LTE technology enables data to be transmitted at speeds faster than W-CDMA, up to 75 Mbps for downloading and up to 37.5 Mbps for uploading. We expect that the faster data transmission speed of the LTE network, combined with our existing 4G nationwide WiBro network, will allow us to offer significantly improved wireless data transmission services, providing our subscribers with faster wireless access to multimedia content. We will continue to make capital expenditures, incur research and development expenses and implement technology upgrades and additional telecommunications services in order to effectively implement continual advances and improvements in telecommunications technology.

Critical Accounting Policies

We have prepared our consolidated financial statements in accordance with IFRS as issued by the IASB. These accounting principles require our management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenses during the years reported. We based our estimates on historical experience and on various other assumptions

51

that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. On an on-going basis, management evaluates its estimates. Actual results may differ from those estimates under different assumptions and conditions.

The fundamental objective of financial reporting is to provide useful information that allows a reader to comprehend our business activities. To aid in that understanding, our management has identified “critical accounting estimates.” These estimates have the potential to have a more significant impact on our financial statements, either because of the significance of the financial statement item to which they relate, or because they require judgment and estimation due to the uncertainty involved in measuring, at a specific point in time, events which are continuous in nature.

These critical accounting estimates include:

• allowances for doubtful accounts;

• useful lives of property and equipment;

• impairment of long-lived assets, including goodwill;

• valuation and impairment of investment securities;

• income taxes;

• deferred revenue relating to service installation fees and initial subscription fees;

• post-employment benefit liabilities; and

• provisions.

Allowances for Doubtful Accounts

Allowance for doubtful accounts is our best estimate of the amount of impairment losses incurred on our existing notes and accounts receivable. We determine the allowance for doubtful notes and accounts receivable based on an aging analysis of balances, historical write-off experience, customer’s or counterparty’s credit ratings and changes in payment terms. Account balances are charged off against the allowance when all means of collection have been exhausted and the potential for recovery is considered remote. Our past experience shows that the possibility of collection is remote after three years of collection effort.

Changes in the allowances for doubtful accounts for our trade and other receivables in the three-year period ended December 31, 2012 are summarized as follows:

	Year Ended December 31,
	2010			2011			2012
	(In millions of Won)
Balance at beginning of year	￦	625,483		￦	646,963		￦	642,357
Provision		158,147			133,442			113,808
Reversal or written-off		(131,931	)		(167,356	)		(127,192	)
Changes in the scope of consolidation		(2,501	)		26,970			12,119
Others		(2,235	)		2,338			2,845
Balance at end of year	￦	646,963		￦	642,357		￦	643,937

52

Changes in the allowances for doubtful accounts for our loans receivables in the three-year period ended December 31, 2012 are summarized as follows:

	Year Ended December 31,
	2010			2011			2012
	(In millions of Won)
Balance at beginning of year	￦	20,536		￦	35,583		￦	43,587
Provision		30,808			30,808			32,914
Reversal or written-off		(8,470	)		(22,804	)		(12,210	)
Others		(7,291	)		—			905
Balance at end of year	￦	35,583		￦	43,587		￦	65,196

If economic or specific industry trends change, we would adjust our allowances for doubtful accounts by recording additional expense or benefit.

Useful Lives of Property and Equipment

Property and equipment are depreciated using the straight-line method over their useful lives as disclosed in Note 2.11 to the Consolidated Financial Statements. An asset’s residual value and useful lives are reviewed and adjusted at the end of each financial reporting period, and are based on historical experience with similar assets as well as taking into account anticipated technological or other changes. If technological changes were to occur more rapidly than anticipated or in a different form than anticipated, the useful lives assigned to these assets may need to be shortened, resulting in the recognition of increased depreciation expense in future periods. A decrease of remaining estimated useful life by one year of our property and equipment would result in an increase of depreciation expense of approximately ￦235 billion in 2012.

Impairment of Long-Lived Assets, including Goodwill

Long-lived assets generally consist of property and equipment and intangible assets, including goodwill. We review long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In addition, we evaluate our long-lived assets for impairment each year as part of our annual forecasting process. An impairment loss would be recognized when the asset’s recoverable amount is less than its carrying amount. The recoverable amount of a long-lived asset is the greater of an asset’s fair value less costs to sell and its value in use. For the purpose of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash flows (cash-generating units). The recoverable amounts of cash-generating units are determined based on value-in-use calculations, which require the use of estimates. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds the estimated recovery value.

Goodwill represents the excess of purchase price paid over the fair value assigned to the identifiable net assets of acquired businesses. The determination of the fair values of goodwill is based on management’s judgment on the expected cash flows of the cash-generating units to which the goodwill is allocated, taking market demand, competition and other economic factors into consideration. The determination of impairments of goodwill involves the use of estimates that include, but are not limited to, the cause, timing and amount of the impairment. Impairment is based on a large number of factors, such as changes in current competitive conditions, expectations of growth in the telecommunications industry, a decline in our expected future cash flows, changes in the future availability of financing, technological obsolescence, discontinuance of services, current replacement costs and prices paid in comparable transactions. The determination of impairment of goodwill requires a significant amount of management’s judgment.

53

Valuation and Impairment of Financial Assets

The fair value of financial instruments, including derivative instruments, that are not traded in an active market is determined by using valuation techniques. Our management uses its judgment to select a variety of methods and makes assumptions that are mainly based on market conditions existing at the end of each reporting period.

We record rights and obligations arising from derivative instruments as assets and liabilities, which are stated at fair value. Gains and losses that result from a change in the fair value of derivative instruments are recognized in current earnings. However, for derivative instruments that qualify for cash flow hedge accounting, the effective portion of the gain or loss on the derivative instruments are recorded as gain or loss on valuation of derivatives for cash flow hedge included in accumulated other comprehensive income or loss, as applicable.

For financial assets, including assets carried at amortized cost and those classified as available-for-sale, we make an annual assessment at the end of each reporting date whether there is objective evidence that a financial asset or a group of financial assets is impaired. For financial assets carried at amortized cost and available-for-sale debt assets, such asset is considered impaired and impairment losses are incurred only if there is objective evidence of impairment as a result of one or more events (a “loss event”) that occurred after the initial recognition of the financial asset, which had an impact on the estimated future cash flows of the financial asset that can reliably be estimated. For equity investments classified as available-for-sale, a significant or prolonged decline in the fair value of the security below its cost, in addition to circumstances described below, may be considered as evidence that the asset is impaired.

For assets carried at amortized cost, the amount of impairment is measured as the difference between the asset’s carrying amount and the present value of estimated future cash flows (excluding future credit losses that have not been incurred) discounted at the asset’s original effective interest rate, and the carrying amount of the asset is reduced and the amount of loss is recognized in the statement of income. Loss on such asset may also be measured based on observable market price if there is an active market for the asset. For assets classified as available-for-sale, the cumulative loss, measured as the difference between the acquisition cost and the current fair value and recognized as accumulated other comprehensive income, less any impairment loss on such financial asset previously recognized in profit or loss, is removed from equity and recognized in the statement of income.

Significant management judgment is involved in evaluating whether a loss event has occurred. The estimates and assumptions used by management to evaluate whether a loss event has occurred can be impacted by many factors, such as the financial condition, earnings capacity and near-term prospects of the company in which we have invested, breach of contract such as default or delinquency in payments, disappearance of an active market for the financial asset and other adverse changes in the payment status of borrowers in the portfolio. The evaluation of these investments is also subject to the overall condition of the economy and its impact on the capital markets.

Income Taxes

We are required to estimate the amount of tax payable or refundable for the current year and the deferred income tax liabilities and assets for the future tax consequences of events that have been reflected in our financial statements or tax returns. This process requires management to make assessments regarding the timing and probability of the tax impact. Actual income taxes could vary from these estimates due to future changes in income tax law or unpredicted results from the final determination of each year’s liability by taxing authorities.

54

We believe that the accounting estimate related to assessing the realizability of deferred tax assets is a “critical accounting estimate” because: (1) it requires management to make assessments about the timing of future events, including the probability of expected future taxable income and available tax planning opportunities, and (2) the impact that changes in actual performance versus these estimates could have on the realization of tax benefits as reported in our results of operations could be material. Management’s assumptions require significant judgment because actual performance has fluctuated in the past and may continue to do so.

Deferred Revenue relating to Service Installation Fees and Initial Subscription Fees

We charge service installation fees and initial subscription fees related to activation of many of our services, which are deferred and recognized as revenue over the expected terms of customer relationships. Our estimate of expected terms of customer relationship is based on the historical rate, which may differ in the future. If the management’s estimation is amended, it may cause significant differences in the timing of revenue recognition and amount recognized.

Post-employment Benefit Liabilities

Our accounting of post-employment benefits, which mainly consist of a defined benefit plan (we began offering a defined contribution plan in December 2012), involves judgments about uncertain events including discount rates, life expectancy, future pay inflation and expected rate of return on plan assets. Any changes in these assumptions will impact the carrying amount of the defined benefit liability. The discount rates used to determine the present value of estimated future cash outflows expected to be required to settle the defined benefit liability, are determined at the end of each reporting period by reference to the yield at the reporting date on high-quality corporate bonds that have maturity dates approximating the terms of our benefits obligations and that are denominated in the same currency in which the benefits are expected to be paid. Other key assumptions for defined benefit liability are based in part on current market conditions. For defined contribution plans, we pay contributions to publicly or privately administered pension insurance plans on a mandatory, contractual or voluntary basis, and we have no further payment obligations once the contributions have been paid.

Provisions

We recognize provisions at the end of the reporting period when we have a present legal or constructive obligation, such as litigation or assets requirement obligations, as a result of past events and an outflow of resources required to settle the obligation is probable and can be reliably estimated. We measure provisions at the present value of the expenditures expected to be required to settle the obligation, which are estimated based on factors such as historical experience. We do not recognize provisions for future operating losses and recognize as interest expense any increase in the provisions due to passage of time. See Notes 2.23, 3.7 and 17 to the Consolidated Financial Statements.

Explanatory Note Regarding Presentation of Certain Financial Information under K-IFRS

In addition to preparing financial statements in accordance with IFRS as issued by the IASB included in this annual report, we also prepare financial statements in accordance with K-IFRS, which we are required to file with the Financial Services Commission and the Korea Exchange under the Financial Investment Services and Capital Markets Act of Korea.

Beginning with our financial statements prepared in accordance with K-IFRS as of and for the year ended December 31, 2012, we are required to adopt certain amendments to K-IFRS No. 1001, Presentation of Financial Statements, as adopted by KASB in 2012. Accordingly, beginning with our consolidated statements of income prepared in accordance with K-IFRS for the year ended December 31, 2012, we present operating profit or loss as an amount of revenue less cost of sales and

55

selling and administrative expenses. The amendments were applied retroactively to our consolidated statements of income prepared in accordance with K-IFRS for the year ended December 31, 2011 and certain of the items in such consolidated statements of income were reclassified to conform to the presentation of operating profit or loss in the consolidated statements of income prepared in accordance with K-IFRS for the year ended December 31, 2012. Prior to the adoption of the amendments to K-IFRS No. 1001, Presentation of Financial Statements, we had presented operating profit or loss in our consolidated statements of income prepared in accordance with K-IFRS as an amount of revenue plus other income less cost of sales, selling and administrative expenses, and other expenses.

In our consolidated statements of income prepared in accordance with IFRS as issued by the IASB included in this annual report, such changes in presentation were not adopted. As a result, the presentation of results from operating activities in our consolidated statements of income prepared in accordance with IFRS as issued by the IASB included in this annual report differs from the presentation of operating profit or loss in the our consolidated statements of income prepared in accordance with K-IFRS. The table below sets forth a reconciliation of our results from operating activities as presented in our consolidated statements of income prepared in accordance with IFRS as issued by the IASB for each of the years ended December 31, 2011 and 2012 to the operating profit or loss as presented in our consolidated statements of income prepared in accordance with K-IFRS after giving effect to the amendments to K-IFRS No. 1001, Presentation of Financial Statements, for each of the corresponding years.

N.A. means not available.

Total operating revenues increased by 11.8%, or ￦2,599 billion, from ￦21,979 billion in 2011 to ￦24,578 billion in 2012 primarily due to increases in our financial service revenues, other revenues and automobile rental service revenues, the impact of which was partially offset by decreases in our fixed-line telephone service revenues and mobile service revenues.

Mobile Services

Our mobile service revenues decreased by 3.4%, or ￦235 billion, from ￦6,813 billion in 2011 to ￦6,578 billion in 2012 primarily due to various rate reduction measures we adopted in August 2011 upon discussion with the Korea Communications Commission, in particular for those applicable to 3G smartphones, the impact of which was further enhanced by a decrease in our mobile subscribers from 16.6 million as of December 31, 2011 to 16.5 million as of December 31, 2012. For a discussion of reduction in rates for our mobile services, see “Item 4.B.—Business Overview—Revenues and Rates—Mobile Services.”

Fixed-line Telephone Services

Our fixed-line telephone service revenues decreased by 11.5%, or ￦438 billion, from ￦3,812 billion in 2011 to ￦3,374 billion in 2012 primarily due to decreases in local service revenues, land-to-mobile interconnection revenues and domestic long-distance revenues. Specifically:

• Local service revenues decreased by 11.7%, or ￦267 billion, from ￦2,286 billion in 2011 to ￦2,019 billion in 2012. The number of local call pulses decreased by 9.3% from 2011 to 2012, and the number of lines in service decreased by 4.9% from 2011 to 2012, primarily due to the substitution effect from increase in usage of mobile telephone services and Internet phone services.

59

• Land-to-mobile interconnection revenues decreased by 15.2%, or ￦119 billion, from ￦782 billion in 2011 to ￦663 billion in 2012 primarily due to a decrease in the number of calls made from landline users to mobile subscribers in 2012 compared to 2011. We recognize as land-to-mobile interconnection revenue the entire amount of the usage charge collected from the landline user for a call initiated by a landline user to a mobile service subscriber.

• Domestic long-distance revenues decreased by 13.0%, or ￦40 billion, from ￦308 billion in 2011 to ￦268 billion in 2012 primarily due to a decrease in the number of domestic long-distance call minutes by 7.7% from 2011 to 2012, primarily due to the substitution effect from increase in usage of mobile telephone services and Internet phone services, as well as a 4.9% decrease in the number of lines in service from 2011 to 2012.

Internet Services

Our Internet service revenues increased by 6.4%, or ￦175 billion, from ￦2,735 billion in 2011 to ￦2,910 billion in 2012 primarily due to an increase in the number of our broadband subscribers from 7.8 million as of December 31, 2011 to 8.0 million as of December 31, 2012, and an increase in the number of IP-TV subscribers from 3.1 million as of December 31, 2011 to 4.0 million as of December 31, 2012, the impact of which was offset in part by an increase in our IP-TV subscribers who participate in bundled products that offer discounts when subscribing to our other services.

Sale of Goods

Revenues from sale of goods increased by 3.4%, or ￦149 billion, from ￦4,441 billion in 2011 to ￦4,590 billion in 2012 primarily due to an increase in the number of smartphones sold, in particular LTE smartphones, that had relatively higher prices.

Data Communications

Data communications service revenues increased by 3.0%, or ￦38 billion, from ￦1,271 billion in 2011 to ￦1,309 billion in 2012 primarily due to an increase in revenues from our network equipment installment, lease and maintenance services, primarily those relating to our IP-based integrated control solutions and equipment.

Financial Services

Financial service revenues increased by 233.3%, or ￦2,324 billion, from ￦996 billion in 2011 to ￦3,320 billion in 2012 primarily due to the recognition of full year income from BC Card Co., Ltd. in 2012, which became our consolidated subsidiary and related revenues became a part of our consolidated revenue starting in October 2011. See Note 35 to the Consolidated Financial Statements.

Automobile Rental

We did not record any automobile rental service revenues in 2011, while we recorded revenues of ￦253 billion in 2012, due to the consolidation of KT Rental Co., Ltd. starting in July 2012 as a result of acquisition of KT Rental’s common stock by Hana Daetoo Securities Co., Ltd. and other investors from the second largest shareholder in July 2012, and the restriction on our control over KT Rental pursuant to a shareholders’ agreement being removed as a result. See Note 35 to the Consolidated Financial Statements.

Others

Other operating revenues increased by 17.4%, or ￦333 billion, from ￦1,911 billion in 2011 to ￦2,244 billion in 2012 primarily due to a ￦112 billion increase in revenues (after intercompany elimination) from H&C Network, which provides call center services to BC Card Co., Ltd. and other

60

financial service providers, as a result of the recognition of full year income from H&C Network in 2012, which became our consolidated subsidiary and related revenues became a part of our consolidated revenue starting in October 2011, a ￦85 billion increase in revenues from KT Skylife as a result of an increase in subscribers in 2012 compared to 2011, and the increases in related installment fees and home shopping network sales, and a ￦56 billion increase in revenues from KT Networks Corporation as a result of an increase in our network construction projects as well as sales in our ecologically safe or “green” information technology equipment. Such increases were offset in part by a ￦47 billion decrease in gains from sale and leaseback of land and buildings to our equity-method investee or special purpose companies specializing in real estate investments, from ￦298 billion in 2011 to ￦251 billion in 2012. See Note 25 to the Consolidated Financial Statements.

Operating Expenses

The following table presents a breakdown of our operating expenses and changes therein for 2011 and 2012.

	For the Year Ended December 31,					Changes
						2011 vs. 2012
	2011		2012			Amount			%

Total operating expenses	￦	20,003	￦	22,893		￦	2,890			14.4	%

N.A. means not available.

(1) Including other operating expenses (which include miscellaneous expenses, insurance, bad debt expenses and repairs), amortization of intangible assets, rent, utilities, taxes and dues, advertising expenses, installation fee, international interconnection fee, loss on disposal of property and equipment, impairment loss on property and equipment, loss on disposal of intangible assets, loss on disposal of investments in associates and joint ventures, impairment loss on investments in associates and joint ventures and donations.

Total operating expenses increased by 14.4%, or ￦2,890 billion, from ￦20,003 billion in 2011 to ￦22,893 billion in 2012 primarily due to increases in card service costs, purchase of handsets, sales commission and depreciation, the impact of which was partially offset by decreases in change of inventories and interconnection charges. Specifically:

• Card service costs increased by 291.4%, or ￦2,063 billion, from ￦708 billion in 2011 to ￦2,771 billion in 2012 primarily due to the consolidation of the full year expenses of BC Card Co., Ltd. in 2012 compared to only three months of expenses in 2011 as described above.

• Our operating expenses related to purchase of handsets increased by 14.2%, or ￦572 billion, from ￦4,021 billion in 2011 to ￦4,593 billion in 2012 primarily due to an increase in the number of smart phones sold. However, the rate of increase in our expenses relating to purchase of handsets was higher than the rate of increase in our revenues relating to sale of goods, due to the decrease in our margins as a result of increased competition.

• Sales commissions, which primarily relate to commissions to our third-party vendors for sales of mobile handsets and mobile and fixed-line service products, increased by 19.6%,

61

or ￦365 billion, from ￦1,865 billion in 2011 to ￦2,230 billion in 2012 primarily due to increases in sales of our LTE mobile service products and LTE smartphones by such third-party vendors, as a result of increases in our total mobile subscribers and subscribers switching to LTE services in 2012

• Depreciation expenses increased by 9.3%, or ￦245 billion, from ￦2,643 billion in 2011 to ￦2,888 billion in 2012 primarily due to an increase in depreciation expenses of ￦160 billion from depreciation expenses of KT Rental’s operating assets, which became our consolidated subsidiary starting in July 2012 as explained above, as well as an increase in depreciation expenses of ￦75 billion from an increase in capital expenditures made during 2012 for LTE-related structures.

These factors were partially offset by the following:

• We recorded operating expenses relating to changes of inventories, which represents a decrease in our inventories, of ￦36 billion in 2011, compared to an increase in inventories of ￦260 billion in 2012, primarily due to temporary year-end accounting treatment of inventories for a shipment of smartphones which were in transit at the end of the year.

• Interconnection charges decreased by 19.3%, or ￦215 billion, from ￦1,116 billion in 2011 to ￦901 billion in 2012 primarily due to decreases in land-to-mobile and mobile-to-mobile interconnection rates charged by other telecommunications operators or are set by the Korea Communications Commission, as applicable, as well as a decrease in the number of calls made from fixed-line phones to mobile phones.

Operating Profit

Due to the factors described above, our operating profit decreased by 14.8%, or ￦292 billion, from ￦1,977 billion in 2011 to ￦1,685 billion in 2012. Our operating margin, which is operating profit as a percentage of operating revenues, decreased from 9.0% in 2011 to 6.9% in 2012.

Finance Income (Costs)

The following table presents a breakdown of our finance income and costs and changes therein for 2011 and 2012.

	For the Year Ended December 31,						Changes
							2011 vs. 2012
	2011			2012			Amount			%

Net finance costs	￦	(370	)	￦	(283	)	￦	87			(23.5	)%

N.A. means not available.

62

Our net finance costs decreased by 23.5%, or ￦87 billion, from ￦370 billion in 2011 to ￦283 billion in 2012 primarily due to our recognition of net foreign currency translation loss in 2011 compared to a net gain in 2012 and an increase in interest income, the impact of which was partially offset by our recognition of net gain on valuation of derivatives in 2011, compared to a net loss in 2012. Specifically:

• We recorded net foreign currency translation loss of ￦79 billion in 2011 compared to net foreign currency translation gain of ￦259 billion in 2012 as the Market Average Exchange Rate of the Won against the U.S. dollar depreciated from ￦1,138.9 to US$1.00 as of December 31, 2010 to ￦1,153.3 to US$1.00 as of December 31, 2011 but it appreciated to ￦1,071.1 to US$1.00 as of December 31, 2012. The impact of such net foreign currency translation gain was partially offset by a net loss on valuation of derivatives discussed below.

• Our interest income increased by 34.4%, or ￦52 billion, from ￦151 billion in 2011 to ￦203 billion in 2012 primarily due to an increase in our average balance of interest-earning assets from 2011 to 2012, including our holdings of cash and cash equivalents.

These factors were partially offset by the following:

• We recorded net gain on valuation of derivatives of ￦55 billion in 2011 compared to net loss on valuation of derivatives of ￦241 billion in 2012, primarily due to an increase in losses from our currency swap contracts due to the appreciation of the exchange rates of the Won against the Japanese Yen and the U.S. dollar from December 31, 2011 to December 31, 2012, whereas we recorded gains in our currency swap contracts in 2011 due to the depreciation of the Won against the U.S. dollar and the Japanese Yen during 2011.

Income (Loss) from Jointly Controlled Entities and Associates

We recorded a loss from jointly controlled entities and associates of ￦3 billion in 2011 compared to a gain from jointly controlled entities and associates of ￦21 billion in 2012 primarily due to a gain of ￦9 billion recorded in connection with our share of KT Rental’s net income until July 2012 (KT Rental became our consolidated subsidiary starting in July 2012 as described above, and any associated gains until July 2012 are recognized under this category), whereas the loss in 2011 primarily resulted from a one-time unrealized loss of ￦30 billion recorded in connection with the sale and leaseback of certain of our properties to K-REALTY CR-REIT I, our equity-method investee specializing in real estate investments established in December 2011.

Income Tax Expense

Our income tax expense decreased by 11.4%, or ￦36 billion, from ￦316 billion in 2011 to ￦280 billion in 2012 primarily due to a decrease in our profit from continuing operations before income tax by 11.2%, or ￦180 billion, from ￦1,603 billion in 2011 to ￦1,423 billion in 2012. See Note 28 to the Consolidated Financial Statements. As a result of the foregoing, our effective tax rate decreased from 19.7% in 2011 to 19.6% in 2012. We had net deferred income tax assets of ￦476 billion as of December 31, 2012.

Profit from Discontinued Operations

We recognized profit from discontinued operations of ￦165 billion in 2011, compared to loss from discontinued operations of ￦32 billion in 2012, primarily due to profits recognized from our sale of our 79.96% controlling interest in New Telephone Company to Vimpel-Communications in June and

63

October 2011, as well as our share of net income of New Telephone Company until the completion of sale, and the loss recognized from our sale of our 93.8% interest in KT Tech, Inc. in August 2012, as well as our share of net loss of KT Tech, Inc. until the completion of sale, which we recorded under this category. See Note 36 to the Consolidated Financial Statements.

Profit for the Period

Due to the factors described above, our profit for the period decreased by 23.5%, or ￦341 billion, from ￦1,452 billion in 2011 to ￦1,111 billion in 2012. Our net income margin, which is profit for the period as a percentage of operating revenues, decreased from 6.6% in 2011 to 4.5% in 2012.

Segment Results—Telecommunication & Convergence Customer Group

Our operating revenues for this segment, prior to adjusting for inter-segment transactions, decreased by 3.0%, or ￦434 billion, from ￦14,580 billion in 2011 to ￦14,146 billion in 2012, primarily due to a decrease in revenues from individual fixed-line telephone subscribers as well as decrease in revenues from our mobile services resulting from a reduction in our mobile service charges.

Our operating profit for this segment, prior to adjusting for inter-segment transactions, decreased by 40.0%, or ￦295 billion, from ￦737 billion in 2011 to ￦442 billion in 2012, as the 3.0% decrease in the segment’s operating revenues outpaced a 1.0% decrease in operating expenses, primarily due to the reasons discussed above. Operating margin, which is operating income as a percentage of total operating revenues prior to adjusting for inter-company sales, decreased from 5.1% in 2011 to 3.1% in 2012.

Depreciation and amortization, prior to adjusting for inter-segment transactions, increased by 5.6%, or ￦117 billion, from ￦2,104 billion in 2011 to ￦2,221 billion in 2012, primarily due to an increase in capital expenditures made for structures relating to our LTE network.

Segment Results—Global & Enterprise Group

Our operating revenues for this segment, prior to adjusting for inter-segment transactions, decreased by 4.0%, or ￦222 billion, from ￦5,587 billion in 2011 to ￦5,365 billion in 2012, primarily due to a decrease in revenues from sales of tangible assets (such as real estate and copper from our decommissioned telephone cables that are recognized in this segment) in 2012 compared to 2011, primarily due to adverse real estate and metal market conditions in 2012.

Our operating profit for this segment, prior to adjusting for inter-segment transactions, decreased by 22.8%, or ￦294 billion, from ￦1,289 billion in 2011 to ￦995 billion in 2012, as the segment recorded a 4.0% decrease in operating revenues while recording a 1.7% increase in operating expenses, primarily due to the reasons discussed above. Operating margin decreased from 23.1% in 2011 to 18.6% in 2012.

Depreciation and amortization, prior to adjusting for inter-segment transactions, decreased by 4.0%, or ￦29 billion, from ￦734 billion in 2011 to ￦705 billion in 2012, primarily due to the spin-off of our satellite business by establishing KT Sat Co., Ltd. in December 2012, and the resulting reduction in related depreciable assets.

Segment Results—Finance/Rental Business Group

Our operating revenues for this segment, prior to adjusting for inter-segment transactions, increased by 267.7%, or ￦2,706 billion, from ￦1,011 billion in 2011 to ￦3,717 billion in 2012,

64

primarily due to the consolidation of full year revenues in 2012 from BC Card Co., Ltd. which became our consolidated subsidiary starting in October 2011 and revenues from KT Rental Co., Ltd. which became our consolidated subsidiary starting in July 2012, as described above.

Our operating profit for this segment, prior to adjusting for inter-segment transactions, increased by 400.0%, or ￦148 billion, from ￦37 billion in 2011 to ￦185 billion in 2012, as the 267.7% increase in the segment’s operating revenues outpaced the 262.6% increase in operating expenses, primarily due to the reasons discussed above. Operating margin, which is operating income as a percentage of total operating revenues prior to adjusting for inter-company sales, increased from 3.7% in 2011 to 5.0% in 2012.

Depreciation and amortization, prior to adjusting for inter-segment transactions, increased by 970.6%, or ￦165 billion, from ￦17 billion in 2011 to ￦182 billion in 2012, primarily due to the effect of consolidation of KT Rental Co., Ltd. and the related assets starting in July 2012 as described above.

Segment Results—Others

Our operating revenues for this segment, prior to adjusting for inter-segment transactions, increased by 16.1%, or ￦652 billion, from ￦4,040 billion in 2011 to ￦4,692 billion in 2012, primarily due to increases in revenues from H&C Network and KT Skylife as described above in “Operating Results—2011 Compared to 2012—Operating Revenue—Others”.

Our operating profit for this segment, prior to adjusting for inter-segment transactions, decreased by 13.6%, or ￦9 billion, from ￦66 billion in 2011 to ￦57 billion in 2012, as the 16.6% increase in operating expenses outpaced the 16.1% increase in operating revenues, primarily due to the reasons discussed above. Operating margin decreased from 1.6% in 2011 to 1.2% in 2012.

Depreciation and amortization, prior to adjusting for inter-segment transactions, increased by 29.1%, or ￦34 billion, from ￦117 billion in 2011 to ￦151 billion in 2012, primarily due to an increase in 2012 of depreciable assets owned by KT Skylife such as home satellite equipment, as a result of an increase in subscribers.

Total operating revenues	￦	20,310	￦	21,979	￦	1,669			8.2	%

Total operating revenues increased by 5.7%, or ￦1,152 billion, from ￦20,120 billion in 2010 to ￦21,272 billion in 2011 primarily due to increases in our other operating revenues, financial service revenues, and sale of goods relating to mobile handset sales, the impact of which was partially offset by a decrease in our fixed-line telephone service revenues.

Mobile Services

Our mobile service revenues decreased by 1.9%, or ￦131 billion, from ￦6,944 billion in 2010 to ￦6,813 billion in 2011 primarily due to various rate reduction measures we adopted in August 2011 upon discussion with the Korea Communications Commission, the impact of which was offset in part by an increase in our mobile subscribers from 16.0 million as of December 31, 2010 to 16.6 million as of December 31, 2011. For a discussion of reduction in rates for our mobile services, see “Item 4.B.—Business Overview—Revenues and Rates—Mobile Services.”

Fixed-line Telephone Services

Our fixed-line telephone service revenues decreased by 12.2%, or ￦529 billion, from ￦4,341 billion in 2010 to ￦3,812 billion in 2011 primarily due to decreases in local service revenues, land-to-mobile interconnection revenues and domestic long-distance revenues. Specifically:

• Local service revenues decreased by 11.0%, or ￦282 billion, from ￦2,568 billion in 2010 to ￦2,286 billion in 2011. The number of local call pulses decreased by 16.0% from 2010 to 2011 primarily due to the substitution effect from increase in usage of mobile telephone services and Internet phone services. However, the effect of such decreases was partially offset by participation by some of our subscribers in optional flat rate plans, as well as an increase in revenues from VoIP services.

66

• Land-to-mobile interconnection revenues decreased by 17.6%, or ￦167 billion, from ￦949 billion in 2010 to ￦782 billion in 2011 primarily due to a decrease in land-to-mobile interconnection rates for 2011 as well as a decrease in the volume of calls between landline users to mobile subscribers.

• Domestic long-distance revenues decreased by 23.6%, or ￦95 billion, from ￦403 billion in 2010 to ￦308 billion in 2011 primarily due to a decrease in the number of domestic long-distance call minutes by 10.2% from 2010 to 2011, primarily due to the substitution effect from increase in usage of mobile telephone services and Internet phone services, as well as an increase in our fixed-line subscribers who terminated their subscription to our optional flat rate plans, and a decrease in interconnection rates received by approximately 2.0% from 2010 to 2011.

Internet Services

Our Internet service revenues increased by 6.0%, or ￦155 billion, from ￦2,580 billion in 2010 to ￦2,735 billion in 2011 primarily due to an increase in the number of IP-TV subscribers from 2.1 million as of December 31, 2010 to 3.1 million as of December 31, 2011, the impact of which was offset in part by an increase in our IP-TV subscribers who participate in bundled products that offer discounts when subscribing to our other services. The revenues from broadband Internet access service decreased by 1.7%, or ￦32 billion, from ￦1,900 billion in 2010 to ￦1,868 billion in 2011.

Sale of Goods

Revenues from sale of goods increased by 10.7%, or ￦429 billion, from ￦4,012 billion in 2010 to ￦4,441 billion in 2011 primarily due to an increase in the number of smartphones sold that had relatively higher margins.

Data Communications

Data communications service revenues decreased by 2.1%, or ￦27 billion, from ￦1,298 billion in 2010 to ￦1,271 billion in 2011 primarily due to service fee discounts offered to government agencies and a decrease in revenues related to Kornet broadband Internet connection service to institutional customers resulting from the expiration of certain leased-line contracts.

Financial Services

Financial service revenues increased by 444.3%, or ￦813 billion, from ￦183 billion in 2010 to ￦996 billion in 2011 primarily due to consolidation of the revenues of BC Card Co., Ltd. (which had revenues of ￦3,205 billion in 2011) starting on October 1, 2011. See Note 35 to the Consolidated Financial Statements.

Others

Other operating revenues increased by 100.7%, or ￦959 billion, from ￦952 billion in 2010 to ￦1,911 billion in 2011 primarily due to consolidation of the revenues of KT Skylife Co., Ltd. (which had revenues of ￦485 billion in 2011) starting on January 1, 2011 and H&C Network (which had revenues of ￦45 billion in 2011) starting on October 1, 2011, as well as a gain of ￦298 billion recognized in connection with the sale and leaseback of certain land and buildings to our equity-method investee specializing in real estate investments in 2011.

(1) Including other operating expenses (which include miscellaneous expenses, insurance, bad debt expenses and repairs), amortization of intangible assets, rent, utilities, taxes and dues, advertising expenses, installation fee, international interconnection fee, loss on disposal of property and equipment, impairment loss on property and equipment, loss on disposal of intangible assets, loss on disposal of investments in associates and joint ventures, impairment loss on investments in associates and joint ventures and donations.

Total operating expenses increased by 9.3%, or ￦1,700 billion, from ￦18,303 billion in 2010 to ￦20,003 billion in 2011 primarily due to increases in other operating expenses (which include miscellaneous expenses, insurance, bad debt expenses and repairs), card service costs, service cost, salaries and wages, commissions and purchase of handsets, the impact of which was partially offset by decreases in depreciation, research and development expenses and interconnection charges. Specifically:

• Other operating expenses increased by 23.0%, or ￦718 billion, from ￦3,115 billion in 2010 to ￦3,833 billion in 2011 primarily due to a one-time expense of ￦200 billion incurred in 2011 relating to the removal of equipment and facilities relating to our 2G PCS services, in connection with our decision to terminate such services in 2011.

• We recorded card service costs of ￦708 billion in 2011, whereas there was no such expense in 2010, as a result of consolidation of the expenses of BC Card Co., Ltd. starting on October 1, 2011.

• Service cost increased by 32.3%, or ￦325 billion, from ￦1,006 billion in 2010 to ￦1,331 billion in 2011 as a result of increases in expenses relating to our systems/network integration business and expenses relating to purchase of multimedia contents from third-party developers.

• Salaries and wages increased by 8.3%, or ￦219 billion, from ￦2,628 billion in 2010 to ￦2,847 billion in 2011 primarily due to an increase in the number of our consolidated employees, as a result of additional consolidated subsidiaries in 2011, including BC Card Co., Ltd. and KT Skylife Co., Ltd. and an increase in average wages.

68

• Commissions, which primarily relate to payments for third-party outsourcing services, including commissions to the call center staff and building security, and discounts on our installment receivables on mobile and fixed-line contracts, increased by 11.2%, or ￦145 billion, from ￦1,297 billion in 2010 to ￦1,442 billion in 2011 primarily due to an increase in discounts on installment receivables as a result of an increase in our mobile subscribers in 2011 and an increase in commissions paid for outsourcing of building security on our real estate holdings.

• Our operating expenses related to purchase of handsets increased by 3.6%, or ￦141 billion, from ￦3,880 billion in 2010 to ￦4,021 billion in 2011 primarily due to an increase in the number of smartphones sold.

These factors were partially offset by the following:

• Depreciation decreased by 7.8%, or ￦224 billion, from ￦2,867 billion in 2010 to ￦2,643 billion in 2011 primarily due to the one-time effect of the shortening of estimated useful lives of assets in the Telecommunication & Convergence Customer Group, which is prospectively applicable from January 1, 2010, the transition date of IFRS, resulting in more assets fully depreciated in 2010 and less assets subject to depreciation in 2011.

• Research and development expenses decreased by 49.7%, or ￦158 billion, from ￦318 billion in 2010 to ￦160 billion in 2011 primarily due to an internal reorganization of our research and development staff, which decreased the number of departments and employees whose expenses are categorized in this category.

• Interconnection charges decreased by 9.0%, or ￦110 billion, from ￦1,226 billion in 2010 to ￦1,116 billion in 2011 primarily due to decreases in land-to-mobile and land-to-land interconnection rates applicable during 2011 compared to 2010.

Operating Profit

Due to the factors described above, our operating profit decreased by 1.5%, or ￦30 billion, from ￦2,007 billion in 2010 to ￦1,977 billion in 2011. Our operating margin, which is operating profit as a percentage of operating revenues, decreased from 9.9% in 2010 to 9.0% in 2011.

Finance Income (Costs)

The following table presents a breakdown of our finance income and costs on a net basis and changes therein for 2010 and 2011.

	For the Year Ended December 31,						Changes
							2010 vs. 2011
	2010			2011			Amount			%

Net finance costs	￦	(358	)	￦	(370	)	￦	(12	)		3.4	%

N.A. means not available.

69

Our net finance costs increased by 3.4%, or ￦12 billion, from ￦359 billion in 2010 to ￦370 billion in 2011 primarily due to our recognition of net foreign currency translation gain in 2010 compared to a net loss in 2011 and an increase in net loss on settlement of derivatives, the impact of which was partially offset by an increase in interest income and an increase in net gain on valuation of derivatives. Specifically:

• We recorded net foreign currency translation gain of ￦33 billion in 2010 compared to net foreign currency translation loss of ￦79 billion in 2011 as the Market Average Exchange Rate of the Won against the U.S. dollar appreciated from ￦1,167.6 to US$1.00 as of December 31, 2009 to ￦1,138.9 to US$1.00 as of December 31, 2010 but it depreciated to ￦1,153.3 to US$1.00 as of December 31, 2011. The impact of such net foreign currency translation loss was partially offset by an increase in net gain on valuation of derivatives discussed below.

• Our net loss on settlement of derivatives increased by twenty-six fold or ￦26 billion, from ￦1 billion in 2010 to ￦27 billion in 2011 primarily due to a significant increase in the size of our settled derivative contracts in 2011 compared to 2010.

These factors were partially offset by the following:

• Our interest income increased by 55.7%, or ￦54 billion, from ￦97 billion in 2010 to ￦151 billion in 2011 primarily due to an increase in our average balance of interest-earning assets from 2010 to 2011, including our holdings of cash and cash equivalents.

• Our net gain on valuation of derivatives, which increased by 685.7%, or ￦48 billion, from ￦7 billion in 2010 to ￦55 billion in 2011 primarily due to an increase in gains from our combined interest rate currency swap contracts due to the depreciation of the exchange rates of the Won against the Japanese Yen and the U.S. dollar from December 31, 2010 to December 31, 2011.

Income (Loss) from Jointly Controlled Entities and Associates

We recorded income from jointly controlled entities and associates of ￦33 billion in 2010 compared to loss from jointly controlled entities and associates of ￦3 billion in 2011 primarily due to an unrealized loss of ￦30 billion recorded in connection with the sale and leaseback of certain of our properties to K-REALTY CR-REIT I, our equity-method investee specializing in real estate investments established in December 2011.

Income Tax Expense

Our income tax expense decreased by 20.2%, or ￦80 billion, from ￦396 billion in 2010 to ￦316 billion in 2011 primarily due to an increase in tax credit carryforwards and deductions, as well as a decrease in profits from continuing operations before income tax. See Note 28 to the Consolidated Financial Statements. Our effective tax rate decreased from 23.6% in 2010 to 19.7% in 2011, primarily due to an increase in tax credit carryforwards and deductions in 2011. We had net deferred income tax assets of ￦405 billion as of December 31, 2011.

Profit from Discontinued Operations

Our profit from discontinued operations increased by 462.2%, or ￦135 billion, from ￦29 billion in 2010 to ￦164 billion in 2011 primarily due to profits recognized from our sale of a 79.96% controlling interest in New Telephone Company to Vimpel-Communications in June and October 2011, as well as our share of net income of New Telephone Company until the completion of sale, which we recorded under this category. See Note 36 to the Consolidated Financial Statements.

70

Profit for the Period

Due to the factors described above, our profit for the period increased by 10.4%, or ￦137 billion, from ￦1,315 billion in 2010 to ￦1,452 billion in 2011. Our net income margin, which is profit for the period as a percentage of operating revenues, increased from 6.5% in 2010 to 6.8% in 2011.

Segment Results—Telecommunication & Convergence Customer Group

Our operating revenues for this segment, prior to adjusting for inter-segment transactions, decreased by 1.3%, or ￦189 billion, from ￦14,769 billion in 2010 to ￦14,580 billion in 2011, primarily due to a decrease in revenues from individual fixed-line telephone subscribers as well as decrease in revenues from our mobile services resulting from a reduction in our mobile service charges.

Segment Results—Global & Enterprise Group

Our operating revenues for this segment, prior to adjusting for inter-segment transactions, increased by 8.7%, or ￦448 billion, from ￦5,139 billion in 2010 to ￦5,587 billion in 2011, primarily due to a one-time gain of ￦238 billion from our sale of our 79.96% controlling interest in New Telephone Company to Vimpel-Communications in June and October 2011, as well as an increase of 119.1%, or ￦162 billion, in revenues from sale of real estate, from ￦136 billion in 2010 to ￦298 billion in 2011, in furtherance of our corporate strategy which began in 2010 to actively liquidate and utilize our idle tangible assets.

Segment Results—Finance/Rental Business Group

Our operating revenues for this segment, prior to adjusting for inter-segment transactions, increased by 426.6%, or ￦819 billion, from ￦192 billion in 2010 to ￦1,011 billion in 2011, primarily due to the consolidation of revenues of BC Card Co., Ltd. and its subsidiaries starting on October 1, 2011 and the consolidation of full year revenues of KT Rental in 2011, which became our consolidated subsidiary and related revenues became a part of our consolidated revenues starting in June 2010.

Segment Results—Others

Our operating revenues for this segment, prior to adjusting for inter-segment transactions, increased by 27.8%, or ￦878 billion, from ￦3,162 billion in 2010 to ￦4,040 billion in 2011 primarily due to the consolidation of the revenues of KT Skylife starting on January 1, 2011.

As explained in “—Overview” above, due to the limitation on availability of necessary financial information resulting from the restructuring of our segment and implementation of the New ERP System in 2012, we are able to provide only operating revenues by segment for 2010 and not the full segment information. See Note 32 to the Consolidated Financial Statements.

Capital Requirements

Historically, our capital requirements consisted principally of purchases of property and equipment and other assets and repayments of borrowings. In our investing activities, we used cash of ￦2,713 billion in 2010, ￦3,208 billion in 2011 and ￦4,278 billion in 2012 for the acquisition of property and equipment, primarily construction-in-progress. In our financing activities, we used cash of ￦5,576 billion in 2010, ￦6,025 billion in 2011 and ￦4,578 billion in 2012 for repayment of borrowings and bonds.

In recent years, we have also required capital for payments of retirement and severance benefits related to our early retirement programs. We recorded payments of severance benefits of ￦960 billion in 2010, ￦361 billion in 2011 and ￦277 billion in 2012. In 2010, our payments were particularly high due to a special voluntary early retirement program held in December 2009 in which we received applications for voluntary early retirement from employees who had been employed by us for more than 15 years and provided them with additional financial incentives to retire early. The special voluntary early retirement program resulted in the early retirement of 5,992 employees out of 25,340 eligible employees.

From time to time, we may also require capital for investments involving acquisitions, including shares of our affiliates, and strategic relationships. For example, we acquired redeemable convertible preferred stock with voting rights and convertible bonds of KT Skylife for ￦246 billion in January 2011, which increased our interest in the company from 32.1% to 53.1% subsequent to exercise of conversion rights. In October 2011, we, through our subsidiary KT Capital Co., Ltd., acquired an additional 1,622,520 common shares of BC Card Co., Ltd. from Woori Bank for approximately ￦252 billion. In December 2012, we submitted a non-binding bid for Vivendi SA’s 53.0% controlling stake in Maroc Telecom SA, a telecommunications service provider based in Rabat, Morocco. While we announced our decision in March 2013 not to submit a formal bid for Maroc Telecom SA, we may consider various investment options with Maroc Telecom SA. Any such additional investments or acquisitions may require significant capital.

Our cash dividends paid to shareholders and non-controlling interests amounted to ￦493 billion in 2010, ￦595 billion in 2011 and ￦497 billion in 2012.

We anticipate that capital expenditures, and, to a lesser extent, repayment of outstanding contractual obligations and commitments will represent the most significant use of funds for the next several years. We may also require capital for purchase of shares of our affiliates as well as investments involving acquisitions and strategic relationships. We compete in the telecommunications sector in Korea, which is rapidly evolving. In recent years, business combinations in the telecommunications industry have significantly changed the competitive landscape of the Korean telecommunications industry. We may need to incur additional capital expenditures to keep up with unexpected developments in rapidly evolving telecommunications technology. There can be no assurance that we will be able to secure funds on satisfactory terms from financial institutions or other sources that are sufficient for our unanticipated needs.

Payments of contractual obligations and commitments will also require considerable resources. In our ordinary course of business, we routinely enter into commercial commitments for various aspects of our operations, including repair and maintenance. We have also provided guarantees to our affiliates. See Note 19 to the Consolidated Financial Statements for a disclosure of the guarantees provided.

The following table sets forth selected information regarding our contractual obligations to make future payments as of December 31, 2012:

(1) Contractual obligations represent contractual liabilities as of the consolidated balance sheet date excluding refundable deposits for telephone installation and accruals for customer call bonus points, which do not have definitive payment schedules.

(2) Does not include any severance payments due beyond 10 years, due to the uncertainties involved in the calculation of such payments.

Capital Resources

We have traditionally met our working capital and other capital requirements principally from cash provided by operations, while raising the remainder of our requirements primarily through debt financing. From time to time, we have also disposed of our treasury shares to meet our capital requirements.

Our major sources of cash have been net cash provided by operating activities, including profits for the period, expenses not involving cash payments such as depreciation and amortization, and proceeds from issuance of bonds and borrowings. We expect that these sources will continue to be our principal sources of cash in the future. Profit for the period was ￦1,315 billion in 2010, ￦1,452 billion in 2011 and ￦1,111 billion in 2012 due to the reasons discussed in Item 5.A. Operating Results. Depreciation and amortization of intangible assets was ￦3,239 billion in 2010, ￦2,992 billion in 2011 and ￦3,308 billion in 2012 primarily reflecting our capital investment activities during the recent years, including our purchase of bandwidths for our operations, investments in LTE-related structures and acquisition of real estate. Cash proceeds from issuance of bonds and borrowings were ￦5,699 billion in 2010, ￦7,225 billion in 2011 and ￦4,256 billion in 2012. As of December 31, 2012, we held 17,476,002 treasury shares.

In 2012, we spun off a portion of our trade receivables relating to handset sales totaling ￦2,733 billion to several special purpose companies, as part of our efforts to improve our cash and asset management. We also recognized a loss on disposal of accounts receivables of ￦15 billion in connection with the transactions. See Note 19 to the Consolidated Financial Statements.

We believe that we have sufficient working capital available to us for our current requirements and that we have a variety of alternatives available to us to satisfy our financial requirements to the extent that they are not met by funds generated by operations, including the issuance of debt securities and bank borrowings denominated in Won and various foreign currencies. For example, we successfully issued US$350 million of 3.875% notes due 2017 in January 2012, three series of notes for an aggregate amount of Japanese Yen 30 billion in January 2013 and three series of notes for an aggregate amount of ￦410 billion in April 2013. See Note 38 to the Consolidated Financial

73

Statements. However, our ability to rely on some of these alternatives could be affected by factors such as the liquidity of the Korean and the global financial markets, prevailing interest rates, our credit rating and the Government’s policies regarding Won currency and foreign currency borrowings. Other factors which could materially affect our liquidity in the future include unanticipated increase in capital expenditures and decrease in cash provided by operations resulting from a significant decrease in demand for our services. We may also need to raise additional capital sooner than we expect in order to fund unanticipated investments and acquisitions.

Our total equity was ￦11,354 billion as of December 31, 2010, ￦12,538 billion as of December 31, 2011 and ￦13,165 billion as of December 31, 2012.

Liquidity

We had a working capital (current assets minus current liabilities) deficit of ￦365 billion as of December 31, 2010, surplus of ￦1,046 billion as of December 31, 2011 and deficit of ￦764 billion as of December 31, 2012. The following table sets forth the summary of our significant current assets for the periods indicated.

	As of December 31,
	2010		2011		2012
	(In billions of Won)
Cash and cash equivalents	￦	1,162	￦	1,445	￦	2,055
Short-term loans receivables, net		725		698		668
Trade and other receivables, net		4,193		6,159		5,878
Inventories, net		711		675		935

Our cash, cash equivalents and net short-term loans receivable maturing within one year totaled ￦1,887 billion as of December 31, 2010, ￦2,143 billion as of December 31, 2011 and ￦2,723 billion as of December 31, 2012. Under IFRS as issued by IASB, bank deposits held at call and all other highly liquid temporary cash instruments within maturities of three months are considered as cash equivalents. Short-term loans receivables primarily consist of loans and other non-derivative financial assets with fixed or determinable payments that are not quoted in an active market with maturities of twelve months or less.

The following table sets forth the summary of our significant current liabilities for the periods indicated:

	As of December 31,
	2010		2011		2012
	(In billions of Won)
Trade and other payables	￦	4,424	￦	5,890	￦	7,216
Borrowings		2,722		2,112		3,187

As of December 31, 2012, we entered into various commitments with financial institutions totaling ￦2,851 billion and US$174 million. See Note 19 to the Consolidated Financial Statements. As of December 31, 2012, ￦37 billion and US$7 million were used under these facilities. We have not had, and do not believe that we will have, difficulty gaining access to short-term financing sufficient to meet our current requirements.

Capital Expenditures

We used cash of ￦2,713 billion in 2010, ￦3,208 billion in 2011 and ￦4,278 billion in 2012 for the acquisition of property and equipment, primarily construction-in-progress.

74

Our current capital expenditure plan, on a non-consolidated basis, calls for the expenditure of approximately ￦3,500 billion in 2013, which may be adjusted depending on market conditions and our results of operations. The principal components of our capital investment plans are:

• approximately ￦1,600 billion in general expansion and modernization of our wireless network infrastructure (including approximately ￦1,300 billion in capital investments for LTE service);

• approximately ￦1,200 billion for general expansion and modernization of our fixed-line network infrastructure; and

• approximately ￦700 billion in capital investments for our other services, including overhead costs.

Inflation

We do not consider that inflation in Korea has had a material impact on our results of operations in recent years. Inflation in Korea was 2.9% in 2010, 4.3% in 2011 and 2.2% in 2012. See “Item 3. Key Information—Item 3.D. Risk Factors—Korea is our most important market, and our current business and future growth could be materially and adversely affected if economic conditions in Korea deteriorate.”

Item 5.C.  Research and Development, Patents and Licenses, Etc.

In order to maintain our leadership in the converging telecommunications business environment and develop additional platforms, services and applications, we operate:

• a technology strategy office;

• a technology development office;

• a central R&D laboratory;

• a network R&D laboratory; and

• a smart grid development center.

As of December 31, 2012, KT Corporation had 5,399 registered patents domestically and 749 registered patents internationally.

The MSIP has the authority to recommend to network service providers that they provide funds for national research and development of telecommunications technology and related projects. The required annual contribution is 0.5% (0.75% for market dominant service providers like us) of revenues attributable to key communications services (excluding revenues from telecommunications service using an allotted frequency if the consideration for such allotted frequency has been paid) from wireless subscribers for the previous year, and is applicable only to those network service providers who have at least ￦30 billion in total sales for the previous year and have recorded no net loss in the current period. Under the policy, the maximum amount of the annual contribution to be made cannot exceed 70.0% of the net profit for the corresponding period of each company. Including such contributions, total expenditures (which include capitalized expenses) on research and development were ￦476 billion in 2010, ￦319 billion in 2011 and ￦549 billion in 2012.

75

In recent years, we have focused our research and development efforts in the following areas:

• a high-definition voice and video communications solution for seamless interoperability between heterogeneous networks;

• a smart-grid platform for global energy control operation centers from South Korea to Finland;

• a smarter health care platform providing individualized self-diagnosis and self-care service especially for hypertensive and diabetic patients;

• a cloud-based video contents distribution channel;

• a mobile contents delivery network (CDN) solution in preparation of future expansion of the CDN market;

• intelligent smart-searching solutions for IPTVs, global positioning navigation systems, and smartphones; and

• a combined operation management system for wired and wireless networks.

See “Item 3. Key Information—Item 3.D. Risk Factors—Forward-looking statements may prove to be inaccurate.”

Item 6.  Directors, Senior Management and Employees

Item 6.A.  Directors and Senior Management

Directors

Our board of directors has the ultimate responsibility for the administration of our affairs. Our articles of incorporation provide for a board of directors consisting of:

• up to three non-independent directors, including the Chief Executive Officer; and

• up to eight outside directors.

All of our directors are elected at the general shareholders’ meeting. If the total assets of a company listed on the KRX KOSPI Market as of the end of the preceding year exceeds ￦2,000 billion,

76

which is the case with us, the Commercial Code of Korea requires such company to have more than three outside directors with more than half of its total directors being outside directors. The term of office for a director is up to three years, but the term is extended to the close of the annual shareholders’ meeting convened with respect to the last full fiscal year of a director’s term of office. If the term of office for a director is not completed and ends before the close of the annual general meeting of shareholders convened with respect to the last full fiscal year of such director’s term of office and a new director is appointed in his or her place, the term of office for such replacement director will coincide with the uncompleted remaining term of office of his or her predecessor.

Under the Commercial Code of Korea, we must establish a committee to nominate candidates for outside directors within the board of directors, and outside directors must make up more than half of the total members of the outside director candidate nominating committee. According to our articles of incorporation, such committee must consist of one non-independent director and all of our outside directors, other than for election of an outside director resulting from the expiration of the term of the office, in which case such outside director whose term is expiring may not be a member of the committee. Our Outside Director Candidate Nominating Committee nominates outside director candidates for appointment at the general shareholders’ meeting.

Upon the request of any director (to the extent that the board of directors does not separately authorize only a particular director to make such request), a meeting of the board of directors will be assembled. The chairperson of the board of directors is elected from among the outside directors by a resolution of the board of directors. The term of office of the chairperson is for one year.

Our current directors are as follows:

Suk-Chae Lee	Chief Executive Officer	January 2009	September 11, 1945		2015

A candidate for Chief Executive Officer is nominated by a committee formed for that purpose. The Chief Executive Officer Candidate Nominating Committee consists of:

(1) All of our executive officers beneficially own less than one percent of the issued shares of KT Corporation in the aggregate.

Item 6.B.  Compensation

Compensation of Directors

In 2012, the total amount of salaries, bonuses (including long-term performance-based incentives for directors) and allowances paid and accrued to all directors of KT Corporation for services in all capacities was approximately ￦4 billion. The aggregate amount accrued by us to provide retirement benefits to such persons was ￦274 million in 2012. Starting in 2009, we no longer pay long-term performance-based incentives to our outside directors.

The chairperson of the Chief Executive Officer Candidate Nominating Committee enters into an employment agreement on our behalf with our Chief Executive Officer. The employment agreement sets certain management targets to be achieved by the Chief Executive Officer, including a target for the amount of “EBITDA” to be achieved in each year. EBITDA is defined as earnings before interest, tax, depreciation and amortization. Failure to achieve certain thresholds below the targets will allow the board of directors to take actions with respect to the Chief Executive Officer’s employment, including proposing to the shareholders’ meeting an early termination of his employment. In addition, the head of each of our functional departments, the president of each of our subsidiaries and the heads of each regional head office have entered into employment agreements with the Chief Executive Officer that provide for similar management targets to be achieved by each of our departments, subsidiaries and regional head offices.

Item 6.C.  Board Practices

As of December 31, 2012, none of our non-independent or outside directors maintained directors’ service contracts with us or with any of our subsidiaries providing for benefits upon termination of employment.

84

Corporate Governance Committee

The Corporate Governance Committee is comprised of four outside directors and one non-independent director, Choon-Ho Lee, E. Han Kim, Byong Won Bahk, Sang Kyun Cha and Hyun-Myung Pyo. The chairperson is Choon-Ho Lee. The committee is responsible for the review of matters with respect to our Corporate Governance Guidelines and our performance under such guidelines to monitor effectiveness of our corporate governance.

Outside Director Candidate Nominating Committee

The Outside Director Candidate Nominating Committee consists of one non-independent director and all of our outside directors, other than for election of an outside director resulting from the expiration of the term of the office, in which case such outside director whose term is expiring may not be a member of the committee. The committee’s duties include reviewing the qualifications of potential candidates and proposing nominees to serve as outside directors on our board of directors to the shareholders at the general meeting of shareholders. The committee members’ terms expire immediately after the adjournment of the shareholders’ meeting where the outside directors are elected.

Evaluation and Compensation Committee

The Evaluation and Compensation Committee is currently comprised of four outside directors, Jong-Hwan Song, Choon-Ho Lee, Keuk Je Sung and Do Kyun Song. The chairperson is Jong-Hwan Song. The committee’s duties include prior review of the Chief Executive Officer’s management goals, terms and conditions proposed for inclusion in the management contract of the Chief Executive Officer, including, but not limited to, determining whether the Chief Executive Officer has achieved the management goals, and the determination of compensation of the Chief Executive Officer and the non-independent directors. The committee members are elected by the board after the closing of the annual meeting, and the term of the committee members is for one year.

Executive Committee

The Executive Committee is currently comprised of all of the non-independent directors. The chairperson is Suk-Chae Lee. The committee’s duties include the establishment and management of branch offices, the acquisition and disposal of real estate having market value between ￦15 billion to ￦30 billion, making investments and providing guarantees between ￦15 billion to ￦30 billion, the disposal and sale of stocks of our subsidiaries, which stocks have a market value of between ￦15 billion and ￦30 billion, provided that no change of control with respect to such subsidiary occurs as a result of such disposal or sale, the authorization of charitable contributions between ￦100 million to ￦1 billion and the issuance of certain debt securities.

Related-Party Transactions Committee

The Related-Party Transactions Committee is currently comprised of four outside directors, Keuk Je Sung, Jong-Hwan Song, Hyun-Nak Lee and Do-Kyun Song. The chairperson is Keuk Je Sung. This committee reviews transactions between KT Corporation and its subsidiaries and ensures compliance with applicable antitrust laws. The committee members are elected by the board after the annual meeting, and the term of the committee members is for one year.

Audit Committee

Under the Commercial Code of Korea, we are required to establish an audit committee comprised of three or more outside directors comprised of at least two-thirds of the audit committee

85

members. Audit Committee members must also meet the applicable independence criteria set forth under the rules and regulations of the Sarbanes-Oxley Act of 2002. The committee is currently comprised of Hyun-Nak Lee, E. Han Kim, Byong Won Bahk and Sang Kyun Cha. The chairperson is Hyun-Nak Lee. Members of the committee are elected by our shareholders at the shareholders’ meeting. Our internal and external auditors report directly to the committee.

The duties of the committee include:

• appointing independent auditors;

• approving the appointment and recommending the dismissal of the internal auditor;

• evaluating performance of independent auditors;

• approving services to be provided by the independent auditors;

• reviewing annual financial statements;

• reviewing audit results and reports;

• reviewing and evaluating our system of internal controls and policies; and

• examining improprieties or suspected improprieties.

In addition, in connection with the shareholders’ meeting, the committee examines the agenda for, and financial statement and other reports to be submitted by the board of directors, at each shareholders’ meeting.

Item 6.D.  Employees

On a non-consolidated basis, we had 32,186 employees as of December 31, 2012, compared to 31,981 employees as of December 31, 2011 and 31,155 employees as of December 31, 2010.

Voluntary Early Retirement Plans

We sponsor a voluntary early retirement plan where we provide additional financial incentives for our employees to retire early, as part of our efforts to improve operational efficiencies. In 2010, 2011 and 2012, 124, 314 and 183 employees, respectively, retired under our voluntary early retirement plan.

Labor Relations

We consider our current relations with our work force to be good. However, in the past, we have experienced opposition from our labor union for our strategy of restructuring to improve our efficiency and profitability by disposing of non-core businesses and reducing our employee base.

As of December 31, 2012, about 78.1% of the employees of KT Corporation were members of the KT Trade Union. On behalf of its members, the Union negotiates with us a collective bargaining agreement every two years, and our current collective bargaining agreement expires on May 23, 2013. The current collective bargaining agreement provides that even in the event of a strike, the minimum number of employees necessary to operate the telecommunications business must continue to work.

86

The Union also negotiates with us an annual agreement on wages on behalf of its members. Under the Act of the Promotion of Worker’s Participation and Cooperation, our Employee-Employer Cooperation Committees, which are composed of representatives of management and labor for each business unit and regional office, meet quarterly to discuss employee grievances, working conditions and potential employee-initiated improvements in service or management.

Recent amendments to the Trade Union and Labor Relations Adjustment Act (“Labor Act”), which became effective on July 1, 2011, allow multiple labor unions to be formed within one company. Therefore, additional labor unions may be formed by our employees. Pursuant to such amendments, our employees formed a new labor union called “KT New Union” in August 2011. The amended Labor Act also requires such multiple unions to consolidate themselves into a single channel when negotiating with the company on behalf of their members and to enter into a single collective bargaining agreement with the company.

Employee Stock Ownership and Benefits

We have an employee stock ownership association, which may purchase on behalf of its members up to 20.0% of any of our shares offered publicly in Korea. The employee stock ownership association owned 1.2% of our issued shares as of December 31, 2012.

In accordance with the National Pension Act of Korea, we contribute an amount equal to 4.5% of an employee’s standard monthly wages, and each employee contributes 4.5% of his or her standard monthly wages, into his or her personal pension account. Our employees, including executive officers as well as non-executive employees, are subject to a pension insurance system, under which we make monthly contributions to the pension accounts of the employees, and upon retirement, such employees are paid the pension amount due from their pension accounts. Prior to April 2011, our executive and non-executive employees were subject to a lump-sum severance payment system, under which they were entitled to receive a lump-sum severance payment upon termination of their employment, based on their length of service and salary level at the time of termination. Starting in April 2011, in accordance with the Korean Employee Retirement Income Security Act, we replaced such lump-sum severance payment system with our current pension insurance system in the form of a defined benefit plan, and also introduced a defined contribution plan in December 2012, with a total combined unfunded portion of approximately ￦548 billion as of December 31, 2012. Lump-sum severance amounts previously accrued prior to our adoption of the current pension insurance system continue to remain payable. We also provide a wide range of fringe benefits to our employees, including housing, housing loans, company-provided hospitals and schools, a company-sponsored pension program, an employee welfare fund, industrial disaster insurance, cultural and athletic facilities, physical education grants, meal allowances, medical examinations and training and resort centers. See “Item 5. Operating and Financial Review and Prospects—Item. 5.A. Operating Results—Salaries and Related Costs.”

Employee Training

The objective of our training program is to develop information and technology specialists who are able to create value for our customers. In order to develop skills of our employees, we require 60 hours of training per year from most of our employees, using individually-tailored curriculums based on individual assessments. We also operate Cyber Academy to provide online classes to our employees, as well as offer various foreign language classes to our employees. In addition, we provide tuition and living expense reimbursements to our high potential individuals who pursue graduate programs in Korea and abroad, as well as provide financial assistance to those who pursue work-related professional licenses or participate in after-work study programs.

Legal Proceedings

In November 2009, 56 of our former customers began a claim against us for an aggregate ￦130 million in damages, alleging that we improperly subscribed them to our optional flat rate plans for fixed-line services without properly obtaining their consent or giving notification. The Seoul Central District Court ruled in our favor on all claims in May 2011, and the plaintiffs filed an appeal in June 2011. The Seoul High Court overruled the plaintiffs’ appeal in December 2011, and the plaintiffs subsequently filed an appeal to the Supreme Court of Korea. In March 2012, the Supreme Court of Korea denied the plaintiffs’ appeal. In connection with this complaint, the Korea Communications Commission investigated our past practices regarding our subscription of customers to optional flat rate plans, and issued an administrative decision in April 2011 which imposed several corrective orders including amendments to our standard terms of use and issuance of an administrative fine of approximately ￦10 billion. We paid such fines to the Korea Communications Commission and implemented its corrective orders.

As part of our decision to apply for reallocation of the 20 MHz bandwidth in the 1.8 GHz spectrum, we applied to the Korea Communications Commission to terminate our 2G PCS services, and on November 23, 2011, the Korea Communications Commission approved our plan. However, on November 30, 2011, approximately 900 of our 2G PCS service subscribers filed a class-action suit against the Korea Communications Commission for its approval of our plan, claiming that we used improper means to reduce our 2G PCS subscribers to comply with regulatory requirements before terminating the 2G PSC services and that the Korea Communications Commission did not consider such factor in approving our plan. On December 6, 2011, the Seoul Administrative Court issued a preliminary injunction, which temporarily suspended our termination of the 2G PCS services until the case went to trial. We immediately appealed the decision and the Seoul High Court overruled the preliminary injunction on December 26, 2011 and reinstated the Korea Communications Commission’s approval. Accordingly, we terminated our 2G PCS services in the Seoul metropolitan area and began the termination process for the rest of Korea on January 3, 2012. On January 12, 2012, the 2G subscribers filed an appeal of the Seoul High Court’s decision with the Supreme Court of Korea, and on February 1, 2012, the Supreme Court of Korea denied such appeal. On January 17, 2012, trial for the original class-action suit filed by the 2G subscribers began in the Seoul Administrative Court. On May 8, 2012, the Seoul Administrative court ruled in our favor on all claims and the plaintiffs subsequently filed an appeal with the Seoul High Court. On September 15, 2012, the Seoul High Court denied the plaintiffs’ appeal, and the plaintiffs appealed the decision to the Supreme Court of Korea. On February 15, 2013, the Supreme Court of Korea denied the plaintiffs’ appeal. There are currently three other similar appeals pending in the Supreme Court of Korea. We expect these appeals to also be resolved in our favor.

In July 2012, the Fair Trade Commission issued to us an administrative fine of approximately ￦5 billion as well as certain corrective orders, after investigating certain pricing and subsidy practices of mobile service carriers and handset manufacturers. Samsung Electronics Co., Ltd., LG Electronics Co., Ltd., Pantech Curitel Co., Ltd., SK Telecom and LG U+ were also issued administrative fines as a result of the investigation. We filed for a stay of execution of the Fair Trade Commission’s decision, and on January 18, 2013, the Supreme Court of Korea granted a stay of execution with respect to the corrective order, and denied the stay of execution with respect to the administrative fine. We paid the entire fine in September 2012. In September 2012, we filed a lawsuit with the Seoul High Court against

89

the Fair Trade Commission to appeal the administrative fine and the corrective order. The first oral argument session was held on December 20, 2012, and the outcome of the lawsuit, and any effect it may have on us, cannot be determined at this time.

Based on investigations conducted in December 2012 and January 2013, the Korea Communications Commission imposed a combined fine of approximately ￦12 billion on SK Telecom, LG U+ and us in January 2013 (our fine being approximately ￦2.9 billion), for providing subsidies that were higher than those allowed under current regulations to new mobile phone purchasers and subscribers, and also imposed temporary suspensions from recruiting new customers ranging from 20 days to 24 days from signing new subscribers. In March 2013, the Korea Communications Commission again imposed a combined fine of approximately ￦5 billion on SK Telecom, LG U+ and us (our fine being approximately ￦1.6 billion), for continuing to offer subsidies during the suspension period.

We are a defendant in various other court proceedings involving claims for civil damages arising in the ordinary course of our business. While we are unable to predict the ultimate disposition of these claims, in the opinion of our management, the ultimate disposition of these claims will not have a material adverse effect on our business, financial condition and results of operations.

Dividends

The table below sets out the annual dividends declared on the outstanding common stock to shareholders of record on December 31 of the years indicated and the interim dividends declared on the outstanding common stock to shareholders of record on June 30 of the years indicated.

Year	Annual Dividend per Common Stock		Interim Dividend per Common Stock		Average Total Dividend per Common Stock
	(In Won)		(In Won)		(In Won)
2008		1,120		—		1,120
2009		2,000		—		2,000
2010		2,410		—		2,410
2011		2,000		—		2,000
2012		2,000		—		2,000

If sufficient profits are available, the Board of Directors may propose annual dividends on the outstanding common stock, which our shareholders must approve by a resolution at the ordinary general meeting of shareholders. This meeting is generally held in March of the following year and if our shareholders at such ordinary general meeting of shareholders approve the annual dividend, we must pay such dividend within one month following the date of such resolution. Typically, we pay such dividends shortly after the meeting. The declaration of annual dividends is subject to the vote of our shareholders, and consequently, there can be no assurance as to the amount of dividends per common stock or that any such dividends will be declared. Interim dividends paid in cash can be declared by a resolution of the board of directors. See “Item 10. Additional Information—Item 10.B. Memorandum and Articles of Association—Dividends” and “Item 12. Description of Securities Other than Equity Securities—Description of American Depositary Shares—Dividends and Distributions.”

The Commercial Code provides that shares of a company of the same class must receive equal treatment. However, major shareholders may consent to receive dividend distributions at a lesser rate than minor shareholders. Previously, the Government consented to receiving a smaller dividend compared to other shareholders. The Government no longer holds any interest in us.

Any cash dividends relating to the shares held in the form of ADSs will be paid to the depositary bank in Won. The deposit agreement provides that, except in certain circumstances, cash

90

dividends received by the depositary bank will be converted by the depositary bank into Dollars and distributed to the holders of the ADRs, less withholding tax, other governmental charges and the depositary bank’s fees and expenses. See “Item 12. Description of Securities Other than Equity Securities—Description of the American Depositary Shares—Dividends and Distributions.”

Item 8.B.  Significant Changes

The KRX KOSPI Market

On January 27, 2005, the Korea Exchange was established pursuant to the Korea Securities and Futures Exchange Act through the consolidation of the Korea Stock Exchange, the Korea Futures Exchange, the KOSDAQ Stock Market, Inc. (the “KOSDAQ”) and the KOSDAQ Committee within the Korea Securities Dealers Association, which was in charge of the management of the KOSDAQ. There are three different markets operated by the Korea Exchange: the KRX KOSPI Market, the KRX KOSDAQ Market and the KRX Derivatives Market. The Korea Exchange has two trading floors located in Seoul, one for the KRX KOSPI Market and one for the KRX KOSDAQ Market, and one trading floor in Busan for the KRX Derivatives Market. The Korea Exchange is a limited liability company, the shares of which are held by (i) securities companies and futures companies that were formerly members of the Korea Stock Exchange or the Korea Futures Exchange, (ii) the Small Business Corporation, (iii) the Korea Securities Finance Corporation and (iv) the Korea Securities Dealers Association. Currently, the Korea Exchange is the only stock exchange in Korea and is operated by membership, having as its members most of the Korean securities companies and some Korean branches of foreign securities companies.

The KRX KOSPI Market has the power in some circumstances to suspend trading in the shares of a given company or to de-list a security. The KRX KOSPI Market also restricts share price movements. All listed companies are required to file accounting reports annually and quarterly and to release immediately all information that may affect trading in a security.

92

The Government has in the past exerted, and continues to exert, substantial influence over many aspects of the private sector business community which can have the intention or effect of depressing or boosting the market. In the past, the Government has informally both encouraged and restricted the declaration and payment of dividends, induced mergers to reduce what it considers excess capacity in a particular industry and induced private companies to offer publicly their securities.

The KRX KOSPI Market publishes the Korea Composite Stock Price Index every two seconds, which is an index of all equity securities listed on the KRX KOSPI Market. The Korea Composite Stock Price Index is calculated using the aggregate value method, in which the market capitalizations of all listed companies are aggregated, subject to certain adjustments, and this aggregate is expressed as a percentage of the aggregate market capitalization of all listed companies as of the base date, January 4, 1980.

Movements in Korea Composite Stock Price Index are set out in the following table together with the associated dividend yields and price earnings ratios.

(1) Dividend yields are based on daily figures. Dividend yields after January 3, 1984 include cash dividends only.

(2) Starting in April 2000, dividend yield and price earnings ratio are calculated based on KOSPI 200, an index of 200 equity securities listed on the KRX KOSPI Market. Starting in April 2000, KOSPI 200 excludes classified companies, companies which did not submit annual reports to the KRX KOSPI Market, and companies which received qualified opinion from external auditors.

(3) The price earnings ratio is based on figures for companies that record a profit in the preceding year.

Shares are quoted “ex-dividend” on the first trading day of the relevant company’s accounting period; since the calendar year is the accounting period for the majority of listed companies, this may account for the drop in the Korea Composite Stock Price Index between its closing level at the end of one calendar year and its opening level at the beginning of the following calendar year.

93

With certain exceptions, principally to take account of a share being quoted “ex-dividend” and “ex-rights,” permitted upward and downward movements in share prices of any category of shares on any day are limited under the rules of the KRX KOSPI Market to 15% of the previous day’s closing price of the shares, rounded down as set out below:

Previous Days’ Closing Price	Rounded Down To
Less than ￦5,000	￦	5
￦5,000 to less than ￦10,000	￦	10
￦10,000 to less than ￦50,000	￦	50
￦50,000 to less than ￦100,000	￦	100
￦100,000 to less than ￦500,000	￦	500
￦500,000 or more	￦	1,000

As a consequence, if a particular closing price is the same as the price set by the fluctuation limit, the closing price may not reflect the price at which persons would have been prepared, or would be prepared to continue, if so permitted, to buy and sell shares. Orders are executed on an auction system with priority rules to deal with competing bids and offers.

Due to a deregulation of restrictions on brokerage commission rates, the brokerage commission rate on equity securities transactions may be determined by the parties, subject to commission schedules being filed with the KRX KOSPI Market by the securities companies. In addition, a securities transaction tax will generally be imposed on the transfer of shares or certain securities representing rights to subscribe for shares at the rate of 0.15% if such transfer is made through the KRX KOSPI Market. A special agricultural and fishery tax of 0.15% of the sales prices will also be imposed on transfer of these shares and securities on the KRX KOSPI Market. See “Item 10. Additional Information—Item 10.A. Taxation—Korean Taxation.”

The number of companies listed on the KRX KOSPI Market, the corresponding total market capitalization at the end of the periods indicated and the average daily trading volume for those periods are set forth in the following table:

(1) Converted at the Concentration Base Rate of The Bank of Korea or the Market Average Exchange Rate as announced by Seoul Money Brokerage Services Limited, as the case may be, at the end of the periods indicated.

The Korean securities markets are principally regulated by the Financial Services Commission of Korea and the Financial Investment Services and Capital Markets Act. The Securities and Exchange Act which regulated the securities markets in the past was replaced with the Financial Investment Services and Capital Markets Act on February 4, 2009. The new law, as did the Securities and Exchange Act, imposes restrictions on insider trading and price manipulation, requires specified information to be made available by listed companies to investors and establishes rules regarding margin trading, proxy solicitation, takeover bids, acquisition of treasury shares and reporting requirements for shareholders holding substantial interests.

Further Opening of the Korean Securities Market

A stock index futures market was opened on May 3, 1996 and a stock index option market was opened on July 7, 1997, in each case at the KRX KOSPI Market. Remittance and repatriation of funds in connection with investment in stock index futures and options are subject to regulations similar to those that govern remittance and repatriation in the context of foreign investment in Korean stocks.

Foreign investors are permitted to invest in warrants representing the right to subscribe for shares of a company listed on the KRX KOSPI Market or registered on the KRX KOSDAQ Market, subject to certain investment limitations. A foreign investor may not acquire such warrants with respect to shares of a class of a company for which the ceiling on aggregate investment by foreigners has been reached or exceeded.

Foreign investors are permitted to invest in all types of corporate bonds, bonds issued by national or local governments and bonds issued in accordance with certain special laws without being subject to any aggregate or individual investment ceiling. The Financial Services Commission sets forth procedural requirements for such investments. Foreigners are permitted to invest in certificates of deposit and repurchase agreements.

Currently, foreigners are permitted to invest in securities including shares of all Korean companies which are not listed on the KRX KOSPI Market nor registered on the KRX KOSDAQ Market and in bonds which are not listed.

Protection of Customer’s Interest in Case of Insolvency of Securities Companies

Under Korean law, the relationship between a customer and a securities company in connection with a securities sell or buy order is deemed to be consignment and the securities acquired by a consignment agent (i.e., the securities company) through such sell or buy order are regarded as

95

belonging to the customer in so far as the customer and the consignment agent’s creditors are concerned. Therefore, in the event of a bankruptcy or reorganization procedure involving a securities company, the customer of the securities company is entitled to the proceeds of the securities sold by the securities company.

When a customer places a sell order with a securities company which is not a member of the KRX KOSPI Market and this securities company places a sell order with another securities company which is a member of the KRX KOSPI Market, the customer is still entitled to the proceeds of the securities sold received by the non-member company from the member company regardless of the bankruptcy or reorganization of the non-member company.

Under the Financial Investment Services and Capital Markets Act, the KRX KOSPI Market is obliged to indemnify any loss or damage incurred by a counterparty as a result of a breach by its members. If a securities company which is a member of the KRX KOSPI Market breaches its obligation in connection with a buy order, the KRX KOSPI Market is obliged to pay the purchase price on behalf of the breaching member. Therefore, the customer can acquire the securities that have been ordered to be purchased by the breaching member.

When a customer places a buy order with a non-member company and the non-member company places a buy order with a member company, the customer has the legal right to the securities received by the non-member company from the member company because the purchased securities are regarded as belonging to the customer in so far as the customer and the non-member company’s creditors are concerned.

As the cash deposited with a securities company is regarded as belonging to the securities company, which is liable to return the same at the request of its customer, the customer cannot take back deposited cash from the securities company if a bankruptcy or reorganization procedure is instituted against the securities company and, therefore, can suffer from loss or damage as a result. However, the Depositor Protection Act provides that Korea Deposit Insurance Corporation will, upon the request of the investors, pay investors up to ￦50 million in case of the securities company’s bankruptcy, liquidation, cancellation of securities business license or other insolvency events. Pursuant to the Financial Investment Services and Capital Markets Act, securities companies are required to deposit the cash received from its customers to the extent the amount not covered by the insurance with the Korea Securities Finance Corporation, a special entity established pursuant to the Securities and Exchange Act

Set-off or attachment of cash deposits by securities companies is prohibited. The premiums related to this insurance are paid by securities companies.

Item 10.  Additional Information

Item 10.A.  Share Capital

Currently, our authorized share capital is 1,000,000,000 shares, which consists of shares of common stock, par value ￦5,000 per share (“Common Shares”) and shares of non-voting preferred stock, par value ￦5,000 per share (“Non-Voting Shares”). Common Shares and Non-Voting Shares together are referred to as “Shares.” Under our articles of incorporation, we are authorized to issue Non-Voting Shares up to one-fourth of our total issued capital stock. As of December 31, 2012, 261,111,808 Common Shares were issued, of which 17,476,002 shares were held by the treasury stock fund or us as treasury shares. We have never issued any Non-Voting Shares. All of the issued Common Shares are fully-paid and non-assessable and are in registered form. We issue share certificates in denominations of 1, 5, 10, 50, 100, 500, 1,000 and 10,000 shares.

Item 10.B.  Memorandum and Articles of Association

This section provides information relating to our capital stock, including brief summaries of material provisions of our articles of incorporation, the Financial Investment Services and Capital Markets Act, the Commercial Code and related laws of Korea, all as currently in effect. The following summaries are subject to, and are qualified in their entirety by reference to, our articles of incorporation and the applicable provisions of the Financial Investment Services and Capital Markets Act and the Commercial Code. We have filed a copy of our articles of incorporation as an exhibit to registration statements under the Securities Act or the Securities Exchange Act previously filed by us.

Dividends

We distribute dividends to our shareholders in proportion to the number of shares owned by each shareholder. No dividends are distributed with respect to shares held by us or our treasury stock fund. The Common Shares represented by the ADSs have the same dividend rights as other outstanding Common Shares.

Holders of Non-Voting Shares are entitled to receive dividends in priority to the holders of Common Shares in an amount of not less than 9% of the par value of the Non-Voting Shares as determined by the board of directors at the time of their issuance, provided that if the dividends on the Common Shares exceed those on the Non-Voting Shares, the Non-Voting Shares will also participate in the distribution of such excess dividend amount in the same proportion as the Common Shares. If the amount available for dividends is less than the aggregate amount of such minimum dividend, the holders of Non-Voting Shares will be entitled to receive such accumulated unpaid dividend in priority to the holders of Common Shares from the dividends payable in respect of the next fiscal year.

We declare dividends annually at the annual general meeting of shareholders which is held within three months after the end of the fiscal year. We pay the annual dividend shortly after the annual general meeting to the shareholders of record as of the end of the preceding fiscal year. We may distribute the annual dividend in cash or in Shares. However, a dividend of Shares must be distributed at par value. If the market price of the Shares is less than their par value, dividends in Shares may not exceed one-half of the annual dividend. We may pay interim dividends in cash once a year to shareholders or registered pledgees who are registered in the registry of shareholders as of June 30 of each fiscal year by a resolution of the board of directors. We have no obligation to pay any annual dividend unclaimed for five years from the payment date.

Under the Commercial Code, we may pay our dividend only out of the excess of our net assets, on a non-consolidated basis, over the sum of (1) our stated capital and (2) the total amount of

97

our capital surplus reserve and earned surplus reserve (the “Legal Reserve”) accumulated up to the end of the relevant dividend period. In addition, we may not pay any dividend unless we have set aside as earned surplus reserve an amount equal to at least 10% of the cash portion of the dividend or unless we have accumulated an earned surplus reserve of not less than one-half of our stated capital. We may not use the Legal Reserve to pay cash dividends but may transfer amounts from the Legal Reserve to capital stock or use the Legal Reserve to reduce an accumulated deficit.

Distribution of Free Shares

In addition to paying dividends in Shares out of our retained or current earnings, we may also distribute to our shareholders an amount transferred from the Legal Reserve to our stated capital in the form of free shares. We must distribute such free shares to all our shareholders in proportion to their existing shareholdings.

Preemptive Rights and Issuance of Additional Shares

We may issue authorized but unissued shares at times and, unless otherwise provided in the Commercial Code, on terms our board of directors may determine. Subject to the limitation described in “Limitation on Shareholdings” below, all our shareholders are generally entitled to subscribe for any newly issued Shares in proportion to their existing shareholdings. We must offer new Shares on uniform terms to all shareholders who have preemptive rights and are listed on our shareholders’ register as of the relevant record date. Under the Commercial Code, we may vary, without shareholders’ approval, the terms of these preemptive rights for different classes of shares. We must give notice to all persons who are entitled to exercise preemptive rights regarding new Shares and their transferability at least two weeks before the relevant record date. Our board of directors may determine how to distribute Shares for which preemptive rights have not been exercised or where fractions of Shares occur.

Under the Commercial Code, it is required that the new Shares, convertible bonds or bonds with warrants be issued to persons other than the existing shareholders solely for the purpose of achieving managerial objectives. Under our articles of incorporation, we may issue new Shares pursuant to a board resolution to persons other than existing shareholders, who in these circumstances will not have preemptive rights, if the new Shares are:

• publicly offered pursuant to Articles 4 and 119 of the Financial Investment Services and Capital Markets Act;

• issued to members of our employee stock ownership association;

• represented by depositary receipts;

• issued upon exercise of stock options granted to our officers and employees;

• issued through an offering to public investors pursuant to Article 165-6 of the Financial Investment Services and Capital Markets Act, the amount of which is no more than 10% of the issued Shares;

• issued in order to satisfy specific needs such as strategic alliance, inducement of foreign funds or new technology, improvement of financial structure or other capital raising requirement; or

• issued to domestic or foreign financial institutions when necessary for raising funds in emergency cases.

98

In addition, we may issue convertible bonds or bonds with warrants, each up to an aggregate principal amount of ￦2,000 billion, to persons other than existing shareholders in the situations described above.

Members of our employee stock ownership association, whether or not they are our shareholders, generally have a preemptive right to subscribe for up to 20.0% of the Shares publicly offered pursuant to the Financial Investment Services and Capital Markets Act. This right is exercisable only to the extent that the total number of Shares so acquired and held by members of our employee stock ownership association does not then exceed 20.0% of the total number of Shares then issued (including in such total both: (i) all issued and outstanding Shares at the time the preemptive rights are exercised; and (ii) all Shares to be newly issued in the applicable share issuance transaction in connection with which such preemptive rights are exercised). As of December 31, 2012, 1.2% of the issued Shares were held by members of our employee stock ownership association.

Limitation on Shareholdings

The Telecommunications Business Act permits maximum aggregate foreign shareholding in us to be 49.0% of our total issued and outstanding Shares with voting rights (including equivalent securities with voting rights, e.g., depositary certificates and certain other equity interests). For the purposes of the foregoing, a shareholder is a “foreign shareholder” if such shareholder is: (1) a foreign person; (2) a foreign government; or (3) a company whose largest shareholder is a foreign person (including any “specially related persons” as determined under the Financial Investment Services and Capital Markets Act) or a foreign government, in circumstances where (i) such foreign person or foreign government holds, in aggregate, 15.0% or more of such company’s total voting shares, and (ii) such company holds at least 1.0% of our total issued and outstanding Shares with voting rights. For the avoidance of doubt, both of conditions (i) and (ii) in the foregoing item (3) must exist for such a company to be counted as a “foreign shareholder” for the purposes of calculating whether the 49.0% foreign shareholding threshold is reached under the Telecommunications Business Act. In addition, the Telecommunications Business Act prohibits a foreign shareholder from being our largest shareholder if such shareholder owns 5.0% or more of our Shares with voting rights. For the purposes of this restriction, any two or more foreign persons or foreign governments who enter into an agreement to act in concert in the exercise of their voting rights will be counted together and prohibited from becoming our largest shareholder in the event that they collectively hold 5.0% or more of our Shares. The Foreign Investment Promotion Act also prohibits any foreign shareholder from being our largest shareholder, if such shareholder owns 5.0% or more of our Shares with voting rights. For the purposes of this restriction under the Foreign Investment Promotion Act, a “foreign shareholder” is defined in the same manner as described above with respect to the foreign shareholding restriction under the Telecommunications Business Act, provided, however, that no exception is made under the Foreign Investment Promotion Act regulations for companies that own less than 1.0% of our Shares (see item (3)(ii) above in this paragraph). A foreigner who has acquired the Shares in excess of such ceiling described above may not exercise its voting rights for shares in excess of such limitation, and the MSIP may require corrective measures to comply with the ownership restrictions.

General Meeting of Shareholders

We hold the annual general meeting of shareholders within three months after the end of each fiscal year. Subject to a board resolution or court approval, we may hold an extraordinary general meeting of shareholders:

• as necessary;

• at the request of shareholders of an aggregate of 3.0% or more of our issued Common Shares;

99

• at the request of shareholders holding an aggregate of 1.5% or more of our issued Shares for at least six months; or

• at the request of our audit committee.

We must give shareholders written notice setting out the date, place and agenda of the meeting at least two weeks before the date of the general meeting of shareholders. However, for holders of less than 1.0% of the total number of issued and outstanding Common Shares, we may give notice by placing at least two public notices in at least two daily newspapers at least two weeks in advance of the meeting. Currently, we use Seoul Shinmun, Maeil Business Newspaper and The Korea Economic Daily published in Seoul for this purpose. Shareholders not on the shareholders’ register as of the record date are not entitled to receive notice of the general meeting of shareholders or attend or vote at the meeting. Holders of Non-Voting Shares are not entitled to receive notice of general meetings of shareholders, but may attend such meetings.

Our general meetings of shareholders are held at our head office, in Sungnam, or if necessary, may be held anywhere near our head office or in Seoul.

Voting Rights

Holders of our Common Shares are entitled to one vote for each Common Share, except that voting rights of Common Shares held by us, or by a corporate shareholder that is more than 10.0% owned by us either directly or indirectly, may not be exercised. The Commercial Code permits cumulative voting, under which voting method each shareholder has multiple voting rights corresponding to the number of directors to be appointed in the voting and may exercise all voting rights cumulatively to elect one director. Our articles of incorporation permit cumulative voting at our shareholders’ meeting. Under the Commercial Code of Korea, any shareholder holding shares equivalent to not less than 1/100 of the total number of shares issued may apply to us for selecting and appointing such directors by cumulative voting.

Our shareholders may adopt resolutions at a general meeting by an affirmative majority vote of the voting shares present or represented at the meeting, where the affirmative votes also represent at least one-fourth of our total voting shares then outstanding. However, under the Commercial Code and our articles of incorporation, the following matters, among others, require approval by the holders of at least two-thirds of the voting shares present or represented at a meeting, where the affirmative votes also represent at least one-third of our total voting shares then outstanding:

• amending our articles of incorporation;

• removing a director;

• reduction of our capital stock;

• effecting any dissolution, merger or consolidation of us;

• transferring the whole or any significant part of our business;

• effecting our acquisition of all of the business of any other company or our acquisition of a part of the business of any other company which will significantly affect our business; or

• issuing any new Shares at a price lower than their par value.

In general, holders of Non-Voting Shares are not entitled to vote on any resolution or receive notice of any general meeting of shareholders. However, in the case of amendments to our articles of

100

incorporation, any merger or consolidation of us, or in some other cases that affect the rights or interests of the Non-Voting Shares, approval of the holders of Non-Voting Shares is required. We may obtain such approval by a resolution of holders of at least two-thirds of the Non-Voting Shares present or represented at a class meeting of the holders of Non-Voting Shares, where the affirmative votes also represent at least one-third of our total outstanding Non-Voting Shares.

Shareholders may exercise their voting rights by proxy. The proxy must present a document evidencing an appropriate power of attorney prior to the start of the general meeting of shareholders. Additionally, shareholders may exercise their voting rights in absentia by submission of signed write-in voting forms. To make it possible for our shareholders to proceed with voting on a write-in basis, we are required to attach the appropriate write-in voting form and related informational material to the notices distributed to shareholders for convening the relevant general meeting of shareholders. Any of our shareholders who desires to vote on such write-in basis must submit their completed and signed write-in voting forms to us no later than one day prior to the date that the relevant general meeting of shareholders is convened.

Holders of ADRs exercise their voting rights through the ADR depositary, an agent of which is the record holder of the underlying Common Shares. Subject to the provisions of the deposit agreement, ADR holders are entitled to instruct the ADR depositary how to vote the Common Shares underlying their ADSs. See “Item 12. Description of Securities Other than Equity Securities—Description of American Depositary Shares—Voting Rights.”

Appraisal Rights of Dissenting Shareholders

In some limited circumstances, including the transfer of the whole or any significant part of our business and our merger or consolidation with another company, dissenting shareholders have the right to require us to purchase their Shares. To exercise this right, shareholders must submit to us a written notice of their intention to dissent before the general meeting of shareholders. Within 20 days after the relevant resolution is passed at a meeting, the dissenting shareholders must request us in writing to purchase their Shares. We are obligated to purchase the Shares of dissenting shareholders within one month after the expiration of the 20-day period. The purchase price for the Shares is required to be determined through negotiation between the dissenting shareholders and us. If we cannot agree on a price through negotiation, the purchase price will be the average of (1) the weighted average of the daily Share prices on the KRX KOSPI Market for the two-month period before the date of the adoption of the relevant board resolution, (2) the weighted average of the daily Share price on the KRX KOSPI Market for the one month period before the date of the adoption of the relevant board resolution and (3) the weighted average of the daily Share price on the KRX KOSPI Market for the one week period before the date of the adoption of the relevant board resolution. However, if we or any of the dissenting shareholders do not accept the purchase price calculated using the above method, the rejecting party may request the court to determine the purchase price. Holders of ADSs will not be able to exercise appraisal rights unless they have withdrawn the underlying common stock and become our direct shareholders.

Register of Shareholders and Record Dates

Our transfer agent, Kookmin Bank, maintains the register of our shareholders at its office in Seoul, Korea. It registers transfers of Shares on the register of shareholders on presentation of the Share certificates.

The record date for annual dividends is December 31. For the purpose of determining the shareholders entitled to annual dividends, the register of shareholders may be closed for the period from the day after the record date to January 31 of the following year. Further, for the purpose of

101

determining the shareholders entitled to some other rights pertaining to the Shares, we may, on at least two weeks’ public notice, set a record date and/or close the register of shareholders for not more than three months. The trading of Shares and the delivery of share certificates may continue while the register of shareholders is closed.

Annual Reports

At least one week before the annual general meeting of shareholders, we must make our annual report and audited consolidated financial statements available for inspection at our principal office and at all of our branch offices. In addition, copies of annual reports, the audited consolidated financial statements and any resolutions adopted at the general meeting of shareholders will be available to our shareholders.

Under the Financial Investment Services and Capital Markets Act, we must file with the Financial Services Commission and the KRX KOSPI Market (1) an annual report within 90 days after the end of our fiscal year and (2) interim reports with respect to the three month period, six month period and nine month period from the beginning of each fiscal year within 45 calendar days following the end of each period. Copies of these reports are or will be available for public inspection at the Financial Services Commission and the KRX KOSPI Market.

Transfer of Shares

Under the Commercial Code, the transfer of Shares is effected by delivery of share certificates. However, to assert shareholders’ rights against us, the transferee must have his name and address registered on our register of shareholders. For this purpose, a shareholder is required to file his name, address and seal with our transfer agent. A non-Korean shareholder may file a specimen signature in place of a seal, unless he is a citizen of a country with a sealing system similar to that of Korea. In addition, a non-resident shareholder must appoint an agent authorized to receive notices on his behalf in Korea and file a mailing address in Korea. The above requirements do not apply to the holders of ADSs.

Under current Korean regulations, Korean securities companies and banks, including licensed branches of non-Korean securities companies and banks, investment management companies, futures trading companies, internationally recognized foreign custodians and the Korea Securities Depository may act as agents and provide related services for foreign shareholders. Certain foreign exchange controls and securities regulations apply to the transfer of Shares by non-residents or non-Koreans. See “Item 10. Additional Information—Item 10.D. Exchange Controls.”

Our transfer agent is Kookmin Bank, located at 24-3, Yoido-dong, Youngdungpo-ku, Seoul, Korea.

Acquisition of Shares by Us

Under the Commercial Code, we may acquire our own Shares by (i) purchasing on the KRX KOSPI Market, or (ii) purchasing from shareholders on a pro rata basis in accordance with the number of shares held by each shareholder. The aggregate purchase price for the Shares may not exceed the total amount available for distribution of dividends at the end of the preceding fiscal year. Moreover, we must acquire our own Shares from dissenting shareholders who exercise their appraisal rights.

Under the Financial Investment Services and Capital Markets Act, we may acquire Shares only by (i) purchasing on the KRX KOSPI Market, (ii) purchasing from shareholders on a pro rata basis in accordance with the number of shares held by each shareholder, or (iii) receiving Shares returned to

102

us upon the cancellation or termination of a trust agreement with a trustee who acquired the Shares by either of the methods indicated above. The aggregate purchase price for the Shares may not exceed the total amount available for distribution of dividends at the end of the preceding fiscal year.

In general, corporate entities in which we own a 50.0% or more equity interest may not acquire our Shares.

As of December 31, 2012, there were 17,476,002 treasury shares including shares held by our treasury stock fund.

Liquidation Rights

In the event of our liquidation, after payment of all debts, liquidation expenses and taxes, our remaining assets will be distributed among shareholders in proportion to their shareholdings. Holders of Non-Voting Shares have no preference in liquidation.

Item 10.C.  Material Contracts

We have not entered into any material contracts since January 1, 2010, other than in the ordinary course of our business. For information regarding our agreements and transactions with certain related parties, see “Item 7.B. Related Party Transactions” and Note 35 to the Consolidated Financial Statements. For a description of certain agreements entered into during the past two years related to our capital commitments and obligations, see “Item 5.B. Liquidity and Capital Resources.”

Item 10.D.  Exchange Controls

General

The Foreign Exchange Transaction Act and the Presidential Decree and regulations under that Act and Decree (collectively the “Foreign Exchange Transaction Laws”) regulate investment in Korean securities by non-residents and issuance of securities outside Korea by Korean companies. Under the Foreign Exchange Transaction Laws, non-residents may invest in Korean securities only in compliance with the provisions of, and to the extent specifically allowed by, these laws or otherwise permitted by the Ministry of Strategy and Finance. The Financial Services Commission has also adopted, pursuant to its authority under the Korean Financial Investment Services and Capital Markets Act, regulations that control investment by foreigners in Korean securities and regulate the issuance of securities outside Korea by Korean companies.

Under the Foreign Exchange Transaction Laws, if the Government deems that certain emergency circumstances, including, but not limited to, the outbreak of natural calamities, wars or grave and sudden changes in domestic or foreign economies, are likely to occur, the Ministry of Strategy and Finance may temporarily suspend the transactions where Foreign Exchange Transaction Laws are applicable, or impose an obligation to deposit or sell capital to certain Korean governmental agencies or financial institutions. In addition, if the Government deems that it is confronted or is likely to be confronted with serious difficulty in movement of capital between Korea and abroad which will bring serious obstacles in carrying out its currency policies, exchange rate policies and other macroeconomic policies, the Ministry of Strategy and Finance may take measures to require any person who performs transactions to deposit such capital to certain Korean governmental agencies or financial institutions.

103

Government Review of Issuance of ADSs

In order for us to issue shares represented by ADSs, we are required to file a prior report of the issuance with the Ministry of Strategy and Finance if our securities and borrowings denominated in foreign currencies issued during the one-year period preceding such filing date exceed US$30 million in aggregate. No further Korean governmental approval is necessary for the initial offering and issuance of the ADSs.

Under current Korean laws and regulations, the depositary bank is required to obtain our prior consent for the number of shares to be deposited in any given proposed deposit which exceeds the difference between (1) the aggregate number of shares deposited by us or with the consent of us for the issuance of ADSs (including deposits in connection with the initial and all subsequent offerings of ADSs and stock dividends or other distributions related to these ADSs) and (2) the number of shares on deposit with the depositary bank at the time of such proposed deposit. We can give no assurance that we would grant our consent, if our consent is required. Therefore, a holder of ADRs who surrenders ADRs and withdraws shares may not be permitted subsequently to deposit those shares and obtain ADRs.

Reporting Requirements for Holders of Substantial Interests

Any person whose direct or beneficial ownership of shares, whether in the form of shares or ADSs, certificates representing the rights to subscribe for Shares and equity-related debt securities including convertible bonds and bonds with warrants (collectively, the “Equity Securities”) together with the Equity Securities beneficially owned by certain related persons or by any person acting in concert with the person accounts for 5.0% or more of the total issued Equity Securities is required to report the status of the holdings to the Financial Services Commission and the KRX KOSPI Market within five business days after reaching the 5.0% ownership interest. In addition, any change in the ownership interest subsequent to the report which equals or exceeds 1.0% of the total issued Equity Securities is required to be reported to the Financial Services Commission and the KRX KOSPI Market within five business days from the date of the change. The required information to be included in the 5.0% report may be different if the acquisition of such shareholding interest is for the purpose of exercising influence over the management, as opposed to an acquisition for investment purposes. Any person reporting the holding of 5.0% or more of the total issued Equity Securities and any person reporting the change in the ownership interest which equals or exceeds 1.0% of the total issued Equity Securities pursuant to the requirements described above must also deliver a copy of such reports to us.

Violation of these reporting requirements may subject a person to criminal sanctions such as fines or imprisonment and may result in a loss of voting rights with respect to the unreported ownership of Equity Securities exceeding 5.0%. Furthermore, the Financial Services Commission may issue an order to dispose of non-reported Equity Securities.

Restrictions Applicable to ADSs

No Korean governmental approval is necessary for the sale and purchase of ADSs in the secondary market outside Korea or for the withdrawal of shares underlying ADSs and the delivery inside Korea of shares in connection with the withdrawal, provided that a foreigner who intends to acquire the shares must obtain an investment registration certificate from the Financial Supervisory Service as described below. In general, the acquisition of the shares by a foreigner must be reported by the foreigner or his standing proxy in Korea immediately to the Governor of the Financial Supervisory Service; provided, however, that in cases where a foreigner acquires shares through the exercise of rights as a holder of ADSs (or other depositary certificates), the foreigner must cause such report to the Governor of the Financial Supervisory Service to be filed by the Korea Securities Depository.

104

Persons who have acquired shares as a result of the withdrawal of shares underlying the ADSs may exercise their preemptive rights for new shares, participate in free distributions and receive dividends on shares without any further governmental approval.

Restrictions Applicable to Shares

As a result of amendments to the Foreign Exchange Transaction Laws and Financial Services Commission regulations adopted in connection with the stock market opening from January 1992, which we refer to collectively as the Investment Rules, foreigners may invest, with limited exceptions and subject to procedural requirements, in all shares of Korean companies, whether listed on the KRX KOSPI Market or the KRX KOSDAQ Market, unless prohibited by specific laws. Foreign investors may trade shares listed on the KRX KOSPI Market or the KRX KOSDAQ Market only through the KRX KOSPI Market or the KRX KOSDAQ Market, except in limited circumstances, including:

• odd-lot trading of shares;

• acquisition of shares (“Converted Shares”) by exercise of warrant, conversion right under convertible bonds or withdrawal right under depositary receipts issued outside of Korea by a Korean company;

• acquisition of shares as a result of inheritance, donation, bequest or exercise of shareholders’ rights, including preemptive rights or rights to participate in free distributions and receive dividends;

• over-the-counter transactions between foreigners of a class of shares for which the ceiling on aggregate acquisition by foreigners, as explained below, has been reached or exceeded;

• shares acquired by foreign direct investment as defined in the Foreign Investment Promotion Act;

• disposal of shares pursuant to the exercise of appraisal rights of dissenting shareholders;

• disposal of shares in connection with a tender offer;

• acquisition of shares by a foreign depositary in connection with the issuance of depositary receipts;

• acquisition and disposal of shares through overseas stock exchange market if such shares are simultaneously listed on the KRX KOSPI Market or the KRX KOSDAQ Market and such overseas stock exchange; and

• arm’s length transactions between foreigners, if all of such foreigners belong to an investment group managed by the same person.

For over-the-counter transactions of shares between foreigners outside the KRX KOSPI Market or the KRX KOSDAQ Market for shares with respect to which the limit on aggregate foreign ownership has been reached or exceeded, an investment broker licensed in Korea must act as an intermediary. Odd-lot trading of shares outside the KRX KOSPI Market or the KRX KOSDAQ Market must involve a licensed investment trader in Korea as the other party. Foreign investors are prohibited from engaging in margin transactions through borrowing shares from a securities company with respect to shares which are subject to a foreign ownership limit.

105

The Investment Rules require a foreign investor who wishes to invest in shares on the KRX KOSPI Market or the KRX KOSDAQ Market (including Converted Shares) to register its identity with the Financial Supervisory Service prior to making any such investment; however, the registration requirement does not apply to foreign investors who acquire Converted Shares with the intention of selling such Converted Shares within three months from the date of acquisition of the Converted Shares or who acquire the shares in an over-the-counter transaction or dispose of shares where such acquisition or disposal is a foreign direct investment as defined in the Foreign Investment Promotion Act. Upon registration, the Financial Supervisory Service will issue to the foreign investor an investment registration certificate that must be presented each time the foreign investor opens a brokerage account with a financial investment business entity. Foreigners eligible to obtain an investment registration certificate include foreign nationals who are individuals residing abroad for more than six months, foreign governments, foreign municipal authorities, foreign public institutions, corporations incorporated under foreign laws, international organizations, funds and associations as defined under the Financial Investment Services and Capital Markets Act. All Korean offices of a foreign corporation as a group are treated as a separate entity from the offices of the corporation outside Korea. However, a foreign corporation or depositary bank issuing depositary receipts may obtain one or more investment registration certificates in its name in certain circumstances as described in the relevant regulations.

Upon a foreign investor’s purchase of shares through the KRX KOSPI Market or the KRX KOSDAQ Market, no separate report by the investor is required because the investment registration certificate system is designed to control and oversee foreign investment through a computer system. However, a foreign investor’s acquisition or sale of shares outside the KRX KOSPI Market or the KRX KOSDAQ Market (as discussed above) must be reported by the foreign investor or his standing proxy to the Governor of the Financial Supervisory Service at the time of each such acquisition or sale; provided, however, that in cases where a foreigner acquires shares through the exercise of rights as a holder of ADSs (or other depositary certificates), the foreigner must cause such report to the Governor of the Financial Supervisory Service to be filed by the Korea Securities Depository; and further provided that a foreign investor must ensure that any acquisition or sale by it of shares outside the KRX KOSPI Market or the KRX KOSDAQ Market in the case of trades in connection with a tender offer, odd-lot trading of shares or trades of a class of shares for which the aggregate foreign ownership limit has been reached or exceeded, is reported to the Governor of the Financial Supervisory Service by the investment trader, the investment broker, the Korea Securities Depository or the financial securities company engaged to facilitate such transaction. A foreign investor may appoint one or more standing proxies from among the Korea Securities Depository, foreign exchange banks, including domestic branches of foreign banks, investment traders, investment brokers, the Korea Securities Depository, financial securities companies and internationally recognized custodians that satisfies all relevant requirements under the Financial Investment Services and Capital Markets Act.

Certificates evidencing shares of Korean companies must be kept in custody with an eligible custodian in Korea. Only the Korea Securities Depository, foreign exchange banks including domestic branches of foreign banks, investment traders, investment brokers, collective investment business entities and internationally recognized custodians satisfying the relevant requirements under the Financial Investment Services and Capital Markets Act are eligible to act as a custodian of shares for a non-resident or foreign investor. A foreign investor must ensure that his custodian deposits its shares with the Korea Securities Depository. However, a foreign investor may be exempted from complying with this deposit requirement with the approval of the Governor of the Financial Supervisory Service in circumstances where compliance with that requirement is made impracticable, including cases where compliance would contravene the laws of the home country of such foreign investor.

106

Under the Investment Rules, with certain exceptions, foreign investors may acquire shares of a Korean company without being subject to any foreign investment ceiling. As one such exception, designated public corporations are subject to a 40.0% ceiling on the acquisition of shares by foreigners in the aggregate and a ceiling on the acquisition of shares by a single foreign investor pursuant to the articles of incorporation of such corporation. Currently, Korea Electric Power Corporation is the only designated public corporation which has set such a ceiling. Furthermore, an investment by a foreign investor of not less than 10.0% of the issued shares with voting rights of a Korean company is defined as a direct foreign investment under the Foreign Investment Promotion Act, which is, in general, subject to the report to, and acceptance, by the Ministry of Knowledge Economy. The acquisition of shares of a Korean company by a foreign investor may also be subject to certain foreign shareholding restrictions in the event that the restrictions are prescribed in each specific law which regulates the business of the Korean company. A foreigner who has acquired shares of our common stock in excess of this ceiling may not exercise his voting rights with respect to the shares of our common stock exceeding the limit.

Under the Foreign Exchange Transaction Laws, a foreign investor who intends to acquire shares must designate a foreign exchange bank at which he must open a foreign currency account and a Won account exclusively for stock investments. No approval is required for remittance into Korea and deposit of foreign currency funds in the foreign currency account. Foreign currency funds may be transferred from the foreign currency account at the time required to place a deposit for, or settle the purchase price of, a stock purchase transaction to a Won account opened at an investment broker or an investment trader. Funds in the foreign currency account may be remitted abroad without any governmental approval.

Dividends on Shares are paid in Won. No governmental approval is required for foreign investors to receive dividends on, or the Won proceeds of the sale of, any shares to be paid, received and retained in Korea. Dividends paid on, and the Won proceeds of the sale of, any shares held by a non-resident of Korea must be deposited either in a Won account with the investor’s investment broker or investment trader or his Won Account. Funds in the investor’s Won Account may be transferred to his foreign currency account or withdrawn for local living expenses up to certain limitations. Funds in the Won Account may also be used for future investment in shares or for payment of the subscription price of new shares obtained through the exercise of preemptive rights.

Investment brokers and investment traders are allowed to open foreign currency accounts with foreign exchange banks exclusively for accommodating foreign investors’ stock investments in Korea. Through these accounts, these investment brokers and investment traders may enter into foreign exchange transactions on a limited basis, such as conversion of foreign currency funds and Won funds, either as a counterparty to or on behalf of foreign investors, without the investors having to open their own accounts with foreign exchange banks.

Item 10.E.  Taxation

The following summary is based upon tax laws of the United States and the Republic of Korea as in effect on the date of this annual report on Form 20-F, and is subject to any change in United States or Korean law that may come into effect after such date. Investors in the shares of common stock or ADSs are advised to consult their own tax advisers as to the United States, Korean or other tax consequences of the purchase, ownership and disposition of such securities, including the effect of any national, state or local tax laws.

107

Korean Taxation

The following summary of Korean tax considerations applies to you as long as you are not:

• a resident of Korea;

• a corporation organized under Korean law; or

• engaged in a trade or business in Korea through a permanent establishment or a fixed base.

Shares or ADSs

Dividends on Shares of Common Stock or ADSs

Unless an applicable tax treaty provides otherwise, we will deduct Korean withholding tax from dividends paid to you either in cash or shares at a rate of 22.0% (including local income tax). If you are a resident of a country that has entered into a tax treaty with Korea, you may qualify for a reduced rate of Korean withholding tax under such a treaty. For example, if you are a qualified resident of the United States for purposes of the US-Korea Tax Treaty (the “Treaty”) and you are the beneficial owner of a dividend, a reduced withholding tax rate of 16.5% (including local income tax) generally will apply. You will not be entitled to claim treaty benefits if you are not the beneficial owner of a dividend.

In order to obtain the benefits of a reduced withholding tax rate under a tax treaty, you must submit to us, prior to the dividend payment date, such evidence of tax residence as may be required by the Korean tax authorities. In the case of ADSs, evidence of tax residence may be submitted to us through the depositary. Excess taxes withheld may be recoverable if you subsequently produce satisfactory evidence that you were entitled to have tax withheld at a lower rate.

If we distribute to you free shares representing a transfer of certain capital reserves or asset revaluation reserves into paid-in capital, that distribution may be a deemed dividend subject to Korean tax.

Capital Gains

Capital gain from a sale of shares of common stock will generally be exempt from Korean taxation if you have owned, together with certain related parties, less than 25.0% of our total issued shares during the year of sale and the five calendar years before the year of sale, and the sale is made through the KRX KOSPI Market, and you have no permanent establishment in Korea. Capital gain earned by a non-Korean holder from a sale of ADSs outside of Korea are exempt from Korean taxation by virtue of the Special Tax Treatment Control Law of Korea (the “STTCL”), provided that the issuance of the ADSs is deemed to be an overseas issuance under the STTCL.

If you are subject to Korean taxation on capital gain from a sale of ADSs, or shares of common stock that you acquired as a result of a withdrawal, your gain will be calculated based on your cost of acquiring the ADSs representing the shares of common stock, although there are no specific Korean tax provisions or rulings on this issue. In the absence of the application of a tax treaty that exempts tax on capital gain, the amount of Korean tax imposed on such capital gains will be the lesser of 11.0% (including local income tax) of the gross realization proceeds or, subject to the production of satisfactory evidence of the acquisition cost and the transaction costs of the ADSs, 22.0% (including local income tax) of the net capital gain.

108

If you are subject to Korean taxation on capital gains from a sale of ADSs, shares of common stock that you acquire as a result of a withdrawal, and you sell your shares of common stock or ADSs, the purchaser or, in the case of a sale of shares of common stock on the KRX KOSPI Market or through a licensed securities company in Korea, the licensed securities company, is required to withhold Korean tax from the sales price in an amount equal to 11% (including local income tax) of the gross realization proceeds and to make payment thereof to the Korean tax authorities, unless you establish your entitlement to an exemption of taxation under an applicable tax treaty or produce satisfactory evidence of your acquisition cost and the transaction costs for the shares of common stock or ADSs. In order to obtain the benefit of an exemption of tax pursuant to a tax treaty, you must submit to the purchaser or the securities company (or through the depositary), as the case may be, prior to the first payment, an exemption application, together with a certificate of your tax residence issued by a competent authority of your residence country. This requirement will not apply to exemptions under Korean tax law. Excess taxes withheld may be recoverable if you subsequently produce satisfactory evidence that you were entitled to have taxes withheld at a lower rate.

Most tax treaties that Korea has entered into provide exemptions for capital gains tax for capital gains from sale and purchase of shares of common stock. However, Korea’s tax treaties with Japan, Austria, Spain and a few other countries do not provide an exemption from such capital gains tax. For example, Article 13 of Korea’s tax treaty with Japan provides that if a taxpayer holding 25% or more (including those shares held by any related party of the taxpayer) of total issued shares of a company in a taxable year sells 5% or more (including those sold by any related party of the taxpayer) of total issued shares of the same company in the same taxable year, the country where the company is a resident may impose tax on such taxpayer.

Inheritance Tax and Gift Tax

Korean inheritance tax is imposed upon (a) all assets (wherever located) of the deceased if at the time of his death he was domiciled in Korea and (b) all property located in Korea which passes on death (irrespective of the domicile of the deceased). Gift tax is imposed in similar circumstances to the above. Taxes are currently imposed at the rate of 10% to 50% if the value of the relevant property is above a certain limit and vary according to the identity of the parties involved.

Under Korean Inheritance and Gift Tax Law, shares issued by a Korean corporation are deemed located in Korea irrespective of where they are physically located or by whom they are owned. It remains unclear whether, for Korean inheritance and gift tax purposes, a non-resident holder of ADSs will be treated as the owner of the shares underlying the ADSs. If such non-resident is treated as the owner of the shares, the heir or donee of such non-resident (or in certain circumstances, the non-resident as the donor) will be subject to Korean inheritance or gift tax at the same rate as described above.

Securities Transaction Tax

If you transfer shares of common stock on the KRX KOSPI Market, you will be subject to the securities transaction tax at a rate of 0.15% and an agriculture and fishery special tax at a rate of 0.15%, calculated based on the sales price of the shares. If you transfer shares of common stock and your transfer is not made on the KRX KOSPI Market you will generally be subject to the securities transaction tax at a rate of 0.5% and will generally not be subject to the agriculture and fishery special tax.

With respect to transfers of ADSs, a tax ruling issued in 2004 by the Korean tax authority appears to hold that depositary receipts (such as the ADSs) constitute share certificates subject to the securities transaction tax. In May 2007, the Seoul Administrative Court held that depositary receipts do

109

not constitute share certificates subject to the securities transaction tax. In 2008, the Seoul Administrative Court’s holding was upheld by the Seoul High Court and was further upheld by the Supreme Court. However, as the Supreme Court dismissed the tax authorities’ appeal without ruling on the substantive law issue, it is not clear if the Supreme Court’s decision for this case will serve as the Supreme Court’s precedent on this issue. Even if depositary receipts (such as the ADSs) constitute share certificates subject to the securities transaction tax under the Securities Transaction Tax Law, sale price of ADSs from a transfer of depositary receipts listed on the New York Stock Exchange, the Nasdaq National Market or other qualified foreign exchanges are exempt from the securities transaction tax.

United States Federal Income Taxation

This summary describes the material U.S. federal income tax consequences to you, if you are a U.S. holder (as defined below), of owning our shares of common stock or ADSs. This summary applies to you only if you hold shares of common stock or ADSs as capital assets for tax purposes. This summary does not apply to you if you are a member of a class of holders subject to special rules, such as:

• a dealer in securities or currencies;

• a trader in securities that elects to use a mark-to-market method of accounting for your securities holdings;

• a bank;

• an insurance company;

• a tax-exempt organization;

• a person that holds shares of common stock or ADSs that are a hedge or that are hedged against interest rate or currency risks;

• a person that holds shares of common stock or ADSs as part of a straddle or conversion transaction for tax purposes;

• a person whose functional currency for tax purposes is not the U.S. dollar; or

• a person that owns or is deemed to own 10% or more of any class of our stock.

This summary is based on laws, treaties and regulatory interpretations in effect on the date hereof, all of which are subject to change, possibly on a retroactive basis.

Please consult your own tax advisers concerning the U.S. federal, state, local and other national tax consequences of purchasing, owning and disposing of shares of common stock or ADSs in your particular circumstances.

For purposes of this summary, you are a “U.S. holder” if you are a beneficial owner of shares of common stock or ADSs and are:

• a citizen or resident of the United States;

• an entity treated as a U.S. domestic corporation; or

• otherwise subject to U.S. federal income tax on a net income basis with respect to income from the shares of common stock or ADSs.

110

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds shares of common stock or ADSs, the U.S. federal income tax treatment of a partner will depend upon the status of the partnership and the activities of the partner. A partner of a partnership holding shares of common stock or ADSs should consult its own tax adviser regarding the U.S. federal income tax consequences to the partner of the acquisition, ownership and disposition by the partnership of shares of common stock or ADSs.

Shares of Common Stock and ADSs

In general, if you hold ADSs, you will be treated as the holder of the shares of common stock represented by those ADSs for U.S. federal income tax purposes, and no gain or loss will be recognized if you exchange an ADS for the shares of common stock represented by that ADS.

Dividends

The gross amount of cash dividends that you receive (prior to deduction of Korean taxes) generally will be subject to U.S. federal income taxation as foreign source dividend income. Dividends paid in Won will be included in your income in a U.S. dollar amount calculated by reference to the exchange rate in effect on the date of your (or, in the case of ADSs, the depositary’s) receipt of the dividend, regardless of whether the payment is in fact converted into U.S. dollars. If such a dividend is converted into U.S. dollars on the date of receipt, you generally should not be required to recognize foreign currency gain or loss in respect of the dividend income. U.S. holders should consult their own tax advisers regarding the treatment of any foreign currency gain or loss on any Won received by U.S. holders that are converted into U.S. dollars on a date subsequent to receipt.

Subject to certain exceptions for short-term and hedged positions, the U.S. dollar amount of dividends received by an individual with respect to the ADSs and common stock will be subject to taxation at the reduced rates applicable to capital gains if the dividends are “qualified dividends.” Dividends paid on the ADSs and common stock will be treated as qualified dividends if (i) we are eligible for the benefits of a comprehensive income tax treaty with the United States that the Internal Revenue Service has approved for the purposes of the qualified dividend rules and (ii) we were not, in the year prior to the year in which the dividend was paid, and are not, in the year in which the dividend is paid, a passive foreign investment company (“PFIC”). The income tax treaty between Korea and the United States (the “Treaty”) has been approved for the purposes of the qualified dividend rules, and we believe we are eligible for benefits under the Treaty. Based on our audited financial statements and relevant market and shareholder data, we do not anticipate being classified as a PFIC. You should consult your own tax advisers regarding the availability of the reduced dividend tax rate in light of your own particular circumstances.

Distributions of additional shares in respect of shares of common stock or ADSs that are made as part of a pro-rata distribution to all of our shareholders generally will not be subject to U.S. federal income tax.

Sales and Other Dispositions

For U.S. federal income tax purposes, gain or loss that you realize on the sale or other disposition of shares of common stock or ADSs will be capital gain or loss, and will be long-term capital gain or loss if the shares of common stock or ADSs were held for more than one year.

Foreign Tax Credit Considerations

You should consult your own tax advisers to determine whether you are subject to any special rules that limit your ability to make effective use of foreign tax credits, including the possible adverse

111

impact of failing to take advantage of benefits under the income tax treaty between the United States and Korea. If no such rules apply, you generally may claim a credit, up to any applicable reduced rates provided under the Treaty, against your U.S. federal income tax liability for Korean taxes withheld from dividends on shares of common stock or ADSs, so long as you have owned the shares of common stock or ADSs (and not entered into certain kinds of hedging transactions) for at least a 16-day period that includes the ex-dividend date. Instead of claiming a credit, you may generally elect to deduct such Korean taxes in computing your taxable income provided that you do not elect to claim a foreign tax credit for any foreign income taxes paid or accrued for the relevant tax year. Foreign tax credits will not be allowed for withholding taxes imposed in respect of certain hedged positions in securities and may not be allowed in respect of arrangements in which your expected economic profit is insubstantial. You may not be able to use the foreign tax credit associated with any Korean withholding tax imposed on a distribution of additional shares that is not subject to U.S. tax unless you can use the credit against United States tax due on other foreign-source income.

Any Korean securities transaction tax or agriculture and fishery special tax that you pay will not be creditable for foreign tax credit purposes.

The calculation of foreign tax credits and, in the case of a U.S. holder that elects to deduct foreign taxes, the availability of deductions involve the application of complex rules that depend on a U.S. holder’s particular circumstances. You should consult your own tax advisers regarding the creditability or deductibility of such taxes.

U.S. Information Reporting and Backup Withholding Rules

Payments in respect of the shares of common stock or ADSs that are made within the United States or through certain U.S.-related financial intermediaries are subject to information reporting and may be subject to backup withholding unless the holder (1) is a corporation or other exempt recipient or (2) provides a taxpayer identification number and certifies that no loss of exemption from backup withholding has occurred. Holders that are not U.S. persons generally are not subject to information reporting or backup withholding. However, such a holder may be required to provide a certification of its non-U.S. status in connection with payments received within the United States or through a U.S.-related financial intermediary.

Item 11.  Quantitative and Qualitative Disclosures About Market Risk

We are exposed to foreign exchange rate and interest rate risks primarily associated with underlying liabilities, and to equity price risk as a result of our investment in equity securities. Our long-term financial policies are annually reported to our Board of Directors, and our Value Management Office conducts financial risk management and assessment. Upon identification and evaluation of our risk exposures, we, having considered various circumstances, enter into derivative financial instruments to try to manage some of such risks. These contracts are entered into with major financial institutions, thereby minimizing the risk of credit loss. The activities of our finance division are subject to policies approved by our foreign exchange and interest rate risk management committee. These policies address the use of derivative financial instruments, including the approval of counterparties, setting of limits and investment of excess liquidity. Our general policy is to hold or issue derivative financial instruments largely for hedging purposes.

For our trading financial instruments, we recognized a valuation gain of ￦21 billion and a valuation loss of ￦0 billion in 2010, a valuation gain of ￦13 billion and a valuation loss of ￦0 billion in 2011 and a valuation gain of ￦0 billion and a valuation loss of ￦0 billion in 2012. For our hedging derivative contracts, we recognized a valuation gain of ￦35 billion, a valuation loss of ￦47 billion and accumulated other comprehensive expense of ￦50 billion in 2010, a valuation gain of ￦54 billion, a valuation loss of ￦9 billion and accumulated other comprehensive income of ￦83 billion in 2011 and a valuation gain of ￦0 billion, a valuation loss of ￦241 billion and accumulated other comprehensive expense of ￦171 billion in 2012. For further details regarding the assets, liabilities, gains and losses recorded relating to our derivative contracts outstanding as of December 31, 2010, 2011 and 2012, see Note 8 to the Consolidated Financial Statements.

Exchange Rate Risk

Substantially all of our cash flow is denominated in Won. We are exposed to foreign exchange risk related to foreign currency denominated liabilities and anticipated foreign exchange payments. Anticipated foreign exchange payments, mostly in Dollars, relate primarily to payments of foreign currency denominated debt, net settlements paid to foreign telecommunication carriers and payments for equipment purchased from foreign suppliers. We have entered into several currency swap contracts, combined interest currency swap contracts and currency forward contracts to hedge our foreign currency risks.

113

The following table shows our assets and liabilities denominated in foreign currency as of December 31, 2010, 2011 and 2012.

As of December 31, 2010, 2011 and 2012, a 10% increase in the exchange rate between the Won and all foreign currencies, with all other variables held constant, would have decreased our income before income tax by ￦61 billion, ￦57 billion and ￦65 billion, respectively, and shareholders’ equity by ￦46 billion, ￦50 billion and ￦53 billion, respectively, with a 10% decrease in the exchange rate having the opposite effect. The foregoing sensitivity analysis assumes that all variables other than foreign exchange rates are held constant, and as such, does not reflect any correlation between foreign exchange rates and other variables, nor our decision to decrease the risk. See Note 34 to the Consolidated Financial Statements.

Interest Rate Risk

We are also subject to market risk exposure arising from changing interest rates. A reduction of interest rates increases the fair value of our debt portfolio, which is primarily of a fixed interest nature. We use, to a limited extent, interest rate swap contracts and combined interest rate and currency swap contracts to reduce interest rate volatility on some of our debt and manage our interest expense by achieving a balanced mixture of floating and fixed rate debt. We entered into several interest rate swap contracts in which we exchange fixed interest rate payments with variable interest rate payments for a specified period, as well as entered into the combined interest rate and currency swap contracts to hedge our interest rate risk.

114

The following table summarizes the principal amounts, fair values, principal cash flows by maturity date and weighted average interest rates of our short-term and long-term liabilities as of December 31, 2012 which are sensitive to exchange rates and/or interest rates. The information is presented in Won, which is our reporting currency.

(1) Weighted average rates of the portfolio at the period end.

As of December 31, 2010, 2011 and 2012, a 100 basis point increase in the market interest rates, with all other variables held constant, would have decreased our profit before income tax by ￦1 billion, ￦1 billion and ￦458 million, respectively, and shareholders’ equity by ￦4 billion, ￦345 million and ￦264 million, respectively, and a 100 basis point decrease in the market interest rates, with all other variables held constant, would have decreased our profit before income tax by ￦17 billion, ￦13 billion and ￦5 billion, respectively, and shareholders’ equity by ￦15 billion, ￦14 billion and ￦5 billion, respectively. The foregoing sensitivity analysis assumes that all variables other than market interest rates are held constant, and as such, does not reflect any correlation between market interest rates and other variables, nor our decision to decrease the risk, but reflects the effects of derivative contracts in place at the time of conducting the analysis.

Equity Price Risk

We are also subject to market risk exposure arising from changes in the equity securities market, which affect the fair value of our equity portfolio. As of December 31, 2010, 2011 and 2012, a 10% increase in the equity indices where our marketable equity securities are listed, with all other variables held constant, would have increased our shareholders’ equity by ￦2 billion, ￦10 billion and ￦5 billion, respectively, with a 10% decrease in the equity index having the opposite effect. The foregoing sensitivity analysis assumes that all variables other than changes in the equity index are held constant, and that our marketable equity instruments had moved according to the historical correlation to the index, and as such, does not reflect any correlation between the equity index and other variables.

Item 12.D.  American Depositary Shares

Fees and Charges

Under the terms of the deposit agreement, holders of our ADSs are required to pay the following service fees to the depositary:

Services	Fees
Issuance of ADSs upon deposit of shares	Up to $0.05 per ADS issued
Delivery of deposited shares against surrender of ADSs	Up to $0.05 per ADS surrendered
Distribution delivery of ADSs pursuant to sale or exercise of rights	Up to $0.02 per ADS held
Distributions of dividends	None
Distribution of securities other than ADSs	Up to $0.02 per ADS held
Other corporate action involving distributions to shareholders	Up to $0.02 per ADS held

Holders of our ADSs are also responsible for paying certain fees and expenses incurred by the depositary and certain taxes and governmental charges such as:

• fees for the transfer and registration of shares charged by the registrar and transfer agent for the shares in Korea (i.e., upon deposit and withdrawal of shares);

• expenses incurred for converting foreign currency into U.S. dollars;

• expenses for cable, telex and fax transmissions and for delivery of securities;

• taxes and duties upon the transfer of securities (i.e., when shares are deposited or withdrawn from deposit); and

• fees and expenses incurred in connection with the delivery or servicing of shares on deposit.

Depositary fees payable upon the issuance and surrender of ADSs are typically paid to the depositary by the brokers (on behalf of their clients) receiving the newly issued ADSs from the depositary and by the brokers (on behalf of their clients) delivering the ADSs to the depositary for surrender. The brokers in turn charge these fees to their clients. Depositary fees payable in connection with distributions of cash or securities to ADS holders and the depositary services fee are charged by the depositary to the holders of record of ADSs as of the applicable ADS record date.

The depositary fees payable for cash distributions are generally deducted from the cash being distributed. In the case of distributions other than cash (i.e., stock dividend, rights), the depositary charges the applicable fee to the ADS record date holders concurrent with the distribution. In the case of ADSs registered in the name of the investor (whether certificated or uncertificated in direct registration), the depositary sends invoices to the applicable record date ADS holders. In the case of

116

ADSs held in brokerage and custodian accounts (via the Depository Trust Company, or DTC), the depositary generally collects its fees through the systems provided by DTC (whose nominee is the registered holder of the ADSs held in DTC) from the brokers and custodians holding ADSs in their DTC accounts. The brokers and custodians who hold their clients’ ADSs in DTC accounts in turn charge their clients’ accounts the amount of the fees paid to the depositary.

In the event of refusal to pay the depositary fees, the depositary may, under the terms of the deposit agreement, refuse to provide the requested service until payment is received or may set off the amount of the depositary fees from any distribution to be made to such holder of ADSs.

The fees and charges that holders of our ADSs may be required to pay may vary over time and may be changed by us and by the depositary. Holders of our ADSs will receive prior notice of such changes.

Fees and Payments from the Depositary to Us

In 2012, we received the following payments, after deduction of applicable U.S. taxes, from the depositary:

Reimbursement of NYSE listing fees:	$	141,837.00
Reimbursement of SEC filing fees:	$	12,917.76
Reimbursement of settlement infrastructure fees (including maintenance fees):	$	204,463.08
Reimbursement of proxy process expenses (printing, postage and distribution):	$	64,952.86
Reimbursement of legal fees (reimbursement received in April 2013 in respect of 2012):	$	282,282.00
Contributions toward our investor relations efforts (including non-deal roadshows, investor conferences and investor relations agency fees):	$	661,503.35

Item 15.  Controls and Procedures

Disclosure Controls and Procedures

Our management has evaluated, with the participation of our Chief Executive Officer and Chief Financial Officer, the effectiveness of our disclosure controls and procedures, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of December 31, 2012. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Based upon our evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report. Our disclosure controls and procedures are designed to ensure that

117

information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Commission’s rules and forms, and that it is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Management’s Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control over financial reporting is a process designed by, and under the supervision of, our principal executive, principal operating and principal financial officers, and effected by our board of directors, management and other personnel, 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.

Our internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records, that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting is not intended to provide absolute assurance that a misstatement of our financial statements would be prevented or detected. 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.

Our management has completed an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2012 based on criteria in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Based on this assessment, management concluded that our internal control over financial reporting was effective as of December 31, 2012.

Samil PricewaterhouseCoopers, an independent registered public accounting firm, which also audited our consolidated financial statements as of, and for the year ended December 31, 2012, as stated in their report which is included herein, has issued an attestation report on the effectiveness of our internal control over financial reporting.

Attestation Report of the Registered Public Accounting Firm

The attestation report of our independent registered public accounting firm on the effectiveness of our internal control over financial reporting is furnished in Item 18 of this Form 20-F.

Changes in Internal Control Over Financial Reporting

We completed the implementation of the New ERP System in July 2012, and changed, established or reevaluated any related parts in our internal control over financial reporting accordingly. We also conducted evaluations prior to and after the implementation of the New ERP System, and confirmed that our internal control over financial reporting remains effective.

Audit Committee Pre-Approval Policies and Procedures

Our audit committee has established pre-approval policies and procedures to pre-approve all audit services to be provided by Samil PricewaterhouseCoopers, our independent registered public accounting firm. Our audit committee’s policy regarding the pre-approval of non-audit services to be provided to us by our independent auditors is that all such services shall be pre-approved by our audit committee. Non-audit services that are prohibited to be provided to us by our independent auditors under the rules of the SEC and applicable law may not be pre-approved. In addition, prior to the granting of any pre-approval, our audit committee must be satisfied that the performance of the services in question will not compromise the independence of our independent registered public accounting firm and does not include delegation of the audit committee’s responsibilities to the management under the Securities Exchange Act of 1934, as amended.

Our audit committee did not pre-approve any non-audit services under the de minimis exception of Rule 2-01 (c)(7)(i)(C) of Regulation S-X as promulgated by the SEC.

Item 16G.  Corporate Governance

The following is a summary of the significant differences between the New York Stock Exchange’s corporate governance standards and those that we follow under Korean law.

NYSE Corporate Governance Standards	KT Corporation’s Corporate Governance Practice
Director Independence
Independent directors must comprise a majority of the board.	The Commercial Code of Korea requires that our board of directors must comprise no less than a majority of outside directors. Our outside directors must meet the criteria for outside directorship set forth under the Commercial Code of Korea. The majority of our board of directors is independent (as defined in accordance with the New York Stock Exchange’s standards), and 8 out of 11 directors are outside directors.

120

NYSE Corporate Governance Standards	KT Corporation’s Corporate Governance Practice
Nomination/Corporate Governance Committee
Listed companies must have a nomination/corporate governance committee composed entirely of independent directors.	We have not established a nomination/corporate governance committee composed entirely of independent directors. However, we maintain an Outside Director Candidate Nominating Committee composed of all of our outside directors and one non-independent director. We also maintain a Corporate Governance Committee comprised of four outside directors and one non-independent director. The committee is responsible for the review of matters with respect to our Corporate Governance Guidelines and our performance under such guidelines to monitor effectiveness of our corporate governance.
Compensation Committee
Listed companies must have a compensation committee composed entirely of independent directors.	We maintain an Evaluation and Compensation Committee composed of four outside directors.
Executive Session
Listed companies must hold meetings solely attended by non-management directors to more effectively check and balance management directors.	Our outside directors hold meetings solely attended by outside directors in accordance with the charter of our board of directors.
Audit Committee
Listed companies must have an audit committee that is composed of more than three directors and satisfy the requirements of Rule 10A-3 under the Exchange Act.	We maintain an Audit Committee comprised of four outside directors who meet the applicable independence criteria set forth under Rule 10A-3 under the Exchange Act.
Shareholder Approval of Equity Compensation Plan
Listed companies must allow their shareholders to exercise their voting rights with respect to any material revision to the company’s equity compensation plan.	We currently have two equity compensation plans: one providing for the grant of stock options to officers and non-independent directors; and an employee stock ownership association program. All material matters related to the granting stock options are provided in our articles of incorporation, and any amendments to the articles of incorporation are subject to shareholders’ approval. Matters related to the employee stock ownership association program are not subject to shareholders’ approval under Korean law.
Corporate Governance Guidelines
Listed companies must adopt and disclose corporate governance guidelines.	We have adopted Corporate Governance Guidelines in March 2007 setting forth our practices with respect to corporate governance matters. Our Corporate Governance Guidelines are in compliance with Korean law but do not meet all requirements established by the New York Stock Exchange for U.S. companies listed on the exchange. A copy of our Corporate Governance Guidelines in Korean is available on our website at www.kt.com.
Code of Business Conduct and Ethics
Listed companies must adopt and disclose a code of business conduct and ethics for directors, officers and employees, and promptly disclose any waivers of the code for executive officers.	We have adopted a Code of Ethics for all directors, officers and employees. A copy of our Code of Ethics in Korean is available on our website at www.kt.com

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of

KT Corporation

In our opinion, the accompanying consolidated statements of financial position and the related consolidated statements of income, of comprehensive income, of changes in shareholders’ equity and of cash flows present fairly, in all material respects, the financial position of KT Corporation and its subsidiaries at December 31, 2012 and 2011 and the results of their operations and their cash flows for the years ended December 31, 2012, 2011 and 2010 in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2012, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the Management’s Annual Report on Internal Control over Financial Reporting in Item 15 of Form 20-F. Our responsibility is to express opinions on these financial statements and on the Company’s internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinion.

A company’s internal control over financial reporting 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. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

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

The headquarters are located in Seongnam City, Gyeonggi Province, Republic of Korea, and the address of its registered head office is 206, Jungja-dong, Bundang-gu, Seongnam City, Gyeonggi Province.

1 These companies are the intermediate parent companies of other subsidiaries and the above financial information is from their consolidated financial statements.

2.     Significant Accounting Policies

The following is a summary of significant accounting policies followed by the Company in the preparation of its financial statements. These policies have been consistently applied to all the periods presented, unless otherwise stated.

2.1     Basis of Preparation

The Company determined to adopt International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”) for the annual periods beginning on or after January 1, 2011.

Financial statements of the Company are based on IFRS. The preparation of financial statements in accordance with IFRS requires the use of certain critical accounting estimates. It also requires management to exercise judgment in the process of applying the Company’s accounting policies. The areas involving a higher degree of judgment and complexity, or the areas where assumptions and estimates are significant to these financial statements are disclosed in Note 3.

2.1.1     Changes in Accounting Policy and Disclosures

(1) New standards, amendments and interpretations not yet adopted

New standards, amendments and interpretations issued but not effective for the annual periods beginning January 1, 2012, and not early adopted by the Company are as follows

F-15

—Amendment of IAS 1, Presentation of Financial Statements

IAS 1, Presentation of Financial Statements, requires other comprehensive income items be presented into two groups on the basis of whether they are potentially reclassifiable to profit or loss subsequently. This is effective for annual periods beginning on or after July 1, 2012, with early adoption permitted. The Company expects that the application of this amendment would not have a material impact on its financial statements.

—Amendments to IAS 19, Employee Benefits

According to the amendments to IAS 19, Employee Benefits, use of a ‘corridor’ approach is no longer permitted, and therefore all actuarial gains and losses incurred are immediately recognized in other comprehensive income. All past service costs incurred from changes in pension plan are immediately recognized, and expected returns on interest costs and plan assets that used to be separately calculated are now changed to calculating net interest expense (income) by applying discount rate used in measuring defined benefit obligation in net defined benefit liabilities (assets). This amendment will be effective for the Company as of January 1, 2013, and the Company is assessing the impact of application of the amended IAS 19 on its consolidated financial statements as of the report date.

—Enactment of IFRS 13, Fair value measurement

IFRS 13, Fair value measurement, aims to improve consistency and reduce complexity by providing a precise definition of fair value and a single source of fair value measurement and disclosure requirements for use across IFRS. IFRS 1 does not extend the use of fair value accounting, but provides guidance on how it should be applied where its use is already required or permitted by other standards within IFRSs. This amendment will be effective for the Company as of January 1, 2013, and the Company expects that it would not have a material impact on the consolidated financial statements.

—IFRS 10, Consolidated Financial Statements

IFRS 10, Consolidated financial statements builds on existing principles by identifying the concept of control as the determining factor in whether an entity should be included within the consolidated financial statements of the parent company. The standard provides additional guidance to assist in the determination of control where this is difficult to assess. This enactment will be effective for annual periods beginning on or after January 1, 2013, and the Company is reviewing the impact of this standard.

—IFRS 11, Joint arrangements

IFRS 11 is a more realistic reflection of joint arrangements by focusing on the rights and obligations of the arrangement rather than its legal form. There are two types of joint arrangement: joint operations and joint ventures. Joint operations arise where a joint operator has rights to the assets and obligations relating to the arrangement and hence accounts for its interest in assets, liabilities, revenue and expenses. Joint ventures arise where the joint operator has rights to the net assets of the arrangement and hence equity accounts for its interest. Proportional consolidation of joint ventures is no longer allowed. This enactment will be effective for annual periods beginning on or after January 1, 2013, and the Company is reviewing the impact of this standard.

F-16

—IFRS 12, Disclosures of interests in other entities

IFRS 12 includes the disclosure requirements for all forms of interests in other entities, including joint arrangements, associates, special purpose vehicles and other off balance sheet vehicles. This enactment will be effective for annual periods beginning on or after January 1, 2013, and the Group is reviewing the impact of this standard.

2.2     Consolidation

The Company’s consolidated financial statements are prepared in accordance with IAS 27, Consolidated and Separate Financial Statements.

(1) Subsidiaries

Subsidiaries are all entities over which the Company has the power to govern the financial and operating policies, generally which have more than half of the voting rights. The existence and effect of potential voting rights that are currently exercisable or convertible are considered when assessing whether the Company controls another entity. The Company also assesses existence of control where it does not have more than 50% of the voting power but is able to govern the financial and operating policies by virtue of de-facto control. De-facto control may arise in circumstances where the size of the Company’s voting rights relative to the size and dispersion of holdings of other shareholders give the company the power to govern the financial and operating policies and others.

Subsidiaries are fully consolidated from the date on which control is transferred to the Company. Subsidiaries are de-consolidated from the date that control ceases.

The Company uses the acquisition method to account for business combinations. The consideration transferred for the acquisition of subsidiary is the fair value of the assets transferred, equity interests issued and liabilities incurred or assumed at the date of acquisition. The consideration transferred includes the fair value of any assets or liability resulting from a contingent consideration arrangement. Identifiable assets acquired, liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date. The Company measures any non-controlling interests in the acquiree on an acquisition-by-acquisition basis, either at fair value or at the non-controlling interests’ proportionate share in the recognized amounts of the acquiree’s identifiable net assets in the event of liquidation. Other non-controlling interests are measured at the fair value unless otherwise required by other standards.

Acquisition-related costs are expensed as incurred. If a business combination is achieved in stages, the acquirer’s previously held ownership of the acquire is re-measured at the fair value at the acquisition date and the resulting gain or loss is recognized as the profit and loss.

Any contingent consideration to be transferred by the Company is recognized at fair value at the acquisition date. Subsequent changes to the fair value of the contingent consideration that is deemed to be an asset or liability is recognized in accordance with IAS 39, either in profit or loss or as a change to other comprehensive income. Contingent consideration that is classified as equity is not remeasured, and its subsequent settlement is accounted for within equity.

The excess of the consideration transferred the amount of any non-controlling interest in the acquiree and the acquisition-date fair value of any previous equity interest in the acquiree over the fair value of the Company’s share of the identifiable net assets acquired is recorded as goodwill. If this is less than the fair value of the net assets of the subsidiary acquired in case of a bargain purchase, the difference is recognized directly in the statement of income.

F-17

Intercompany transactions, balances and unrealized gains and losses on transactions between consolidated companies are eliminated after considering impairment of the asset transferred. Unrealized gains and losses are eliminated after recognizing impairment of transferred assets, accounting policies of subsidiaries have been changed where necessary to ensure consistency with the policies adopted by the Company.

(2) Changes in ownership interests in subsidiaries without change of control

Transactions with non-controlling interests that do not result in loss of control are accounted for as equity transactions; that is, as transactions with the owners in their capacity as owners. The difference between fair value of any consideration paid and the relevant share acquired of the carrying value of net assets of the subsidiary is recorded in equity. Gains or losses on disposals to non-controlling interests are also recorded in equity.

(3) Disposal of subsidiaries

When the Company ceases to have control any retained interest in the entity is re-measured to its fair value at the date when control is lost, with the change in carrying amount recognized in profit or loss. The fair value is the initial carrying amount for the purposes of subsequently accounting for the retained interest as an associate, joint venture or financial asset. In addition, any amounts previously recognized in other comprehensive income in respect of that entity are accounted for as if the Company had directly disposed of the related assets or liabilities. This may mean that amounts previously recognized in other comprehensive income are reclassified to profit or loss.

(4) Associates

Associates are all entities over which the Company has significant influence but not control, generally holding of between 20% and 50% of the voting rights. Investments in associates are accounted for using the equity method and are initially recognized at cost. The Company’s investment in associates includes goodwill identified on acquisition, net of any accumulated impairment loss.

If the ownership interest in an associate is reduced but significant influence is retained, only a proportionate share of the amounts previously recognized in other comprehensive income is reclassified to profit or loss where appropriate.

The Company’s share of its associates’ post-acquisition profits or losses is recognized in the statement of income, and its share of post-acquisition movements in other reserves is recognized in reserves. The cumulative post-acquisition movements are adjusted against the carrying amount of the investment. When the Company’s share of losses of an associate equals or exceeds its interest in the associate, including any unsecured receivables, the Company does not recognize further losses, unless it has incurred obligations or made payments on behalf of the associate.

The Company assesses at the end of each reporting period whether there is any objective evidence that an investment in associates is impaired. If any such evidence exists, the Company should recognize difference between recoverable amount and carrying amount of the associates as impairment loss.

Unrealized gains on transactions between the Company and its associates are eliminated to the extent of the Company’s interest in the associates. Unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. Accounting policies of associates have been changed, where necessary, to ensure consistency with the policies adopted by the Company. Dilution gains and losses arising from investments in associates are recognized in the statement of income.

F-18

(5) Jointly controlled entities

A joint venture is a contractual arrangement whereby two or more parties (ventures) undertake an economic activity that is subject to joint control. As with associates, investments in jointly controlled entities are accounted for using the equity method and are initially recognized at cost. The Company’s investment in jointly controlled entities includes goodwill identified on acquisition, net of any accumulated impairment loss. The Company does not recognize its share of profits or losses from the joint venture that result from the Company’s purchase of assets from the joint venture until it re-sells the assets to an independent party. However, a loss on the transaction is recognized immediately if the loss provides evidence of a reduction in the net realizable value of current assets, or an impairment loss

2.3    Segment Reporting

Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision-maker (Note 32). The chief operating decision-maker is responsible for making strategic decisions on resource allocation and performance assessment of the operating segments.

2.4    Foreign Currency Translation

(1) Functional and presentation currency

Items included in the financial statements of each of the consolidated companies are measured using the currency of the primary economic environment in which the entity operates (“the functional currency”). The consolidated financial statements are presented in ‘Korean won’, which is the Controlling Company’s functional and presentation currency.

(2) Transactions and balances

Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transactions or valuation where items are re-measured. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at year-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognized in the statement of income, except when deferred in other comprehensive income as qualifying cash flow hedges.

Changes in the fair value of monetary securities denominated in foreign currency classified as available-for-sale are analyzed between translation differences resulting from changes in the amortized cost of the security and other changes in the carrying amount of the security. Translation differences related to changes in amortized cost are recognized in profit or loss, and other changes in carrying amount are recognized in other comprehensive income.

Foreign currency translation differences on non-monetary financial assets and liabilities are recognized as a part of the fair value gain or loss. Translation differences on equity instruments classified as available-for-sale are included in other comprehensive income, while translation differences on equity instruments classified as financial assets and liabilities at fair value through profit or loss are included in the statement of income.

F-19

(3) Overseas subsidiaries

The functional currency of all overseas subsidiaries is the local currency of the countries where the subsidiaries are located. The results and financial position of all consolidated companies whose functional currency is different from the presentation currency are translated into the presentation currency as follows:

• Assets and liabilities are translated at the closing rate at the end of the reporting period;

• Income and expenses are translated at an average rate for the period. However, if exchange rates fluctuate significantly, the actual rate at the date of the transaction is used; and

• All resulting exchange differences are recognized in other comprehensive income.

When the Company ceases to have control, exchange differences that were recorded in equity are recognized in profit and loss on disposal of the investment.

Goodwill and fair value adjustments arising from the acquisition of a foreign entity are treated as assets and liabilities of the foreign entity. These are presented in functional currency of the foreign entity, and translated at the closing rate.

2.5    Cash and Cash Equivalents

Cash and cash equivalents include cash on hand, deposits held at call with banks, and other short-term highly liquid investments with original maturities of less than three months.

2.6    Financial Assets and Liabilities

(1) Classification

The Company classifies its financial instruments in the following categories: financial assets and liabilities at fair value through profit or loss, loans and receivables, available-for-sale financial assets, held-to-maturity investments and financial liabilities measured at amortized cost. Management determines the classification of financial instruments at initial recognition.

1) Financial assets and liabilities at fair value through profit or loss

This category comprises two sub-categories: financial assets and liabilities classified as held for trading, and financial assets and liabilities designated by the Company as at fair value through profit or loss upon initial recognition.

A financial asset and liability is classified as held for trading if either:

• It is acquired or incurred principally for the purpose of selling or reacquisition in the short term, or

• It is derivatives that are not subject to hedge accounting or a financial instrument that contains embedded derivative.

F-20

The Company may designate certain financial assets and liabilities, other than held for trading, upon initial recognition as at fair value through profit or loss when one of the following conditions is met:

• It eliminates or significantly reduces a measurement or recognition inconsistency (sometimes referred to as ‘an accounting mismatch’) that would otherwise arise from measuring assets or liabilities or recognizing the gains and losses on them on different bases.

• A group of financial assets is managed and its performance is evaluated on a fair value basis, in accordance with a documented risk management or investment strategy, and information about the group is provided internally on that basis to the Company’s key management personnel.

• A contract contains one or more embedded derivatives; the Company may designate the entire hybrid (combined) contract as a financial asset at fair value through profit or loss if allowed by IAS 39, Financial Instruments: Recognition and measurement.

Financial assets and liabilities at fair value through profit or loss are classified as current assets and current liabilities, respectively.

2) Loans and receivables

Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. They are included in current assets, except for maturities greater than 12 months after the end of the reporting period, which are classified as non-current assets. The Company’s loans and receivables are classified as ‘cash and cash equivalents’, ‘trade and other receivables’, ‘loans receivable’, ‘finance lease receivables’ and ‘other financial assets’ in the financial statements.

3) Available-for-sale financial assets

Available-for-sale financial assets are non-derivatives that are either designated in this category or not classified in any of the other categories. They are included in non-current assets unless the investment matures or management intends to dispose of it within 12 months of the end of the reporting period. The available-for-sale financial assets of the Company are classified to the ‘other financial assets’ in the financial statements.

4) Held-to-maturity investments

Held-to-maturity financial assets are non-derivative financial assets with fixed or determinable payments and fixed maturities that the Company’s management has the positive intention and ability to hold to maturity and are categorized in ‘other financial assets’ in the financial statements. If the Company were to sell other than an insignificant amount of held-to-maturity financial assets, the whole category would be tainted and reclassified as available-for-sale financial assets. Held-to-maturity financial assets are included in non-current assets, except for those with maturities of less than 12 months of the end of the reporting period which are classified as current assets.

5) Financial liabilities measured at amortized cost

The Company classifies non-derivative financial liabilities as financial liabilities measured at amortized cost, except for financial liabilities at fair value through profit or loss or for financial liabilities

F-21

that arise when a transfer of a financial asset does not qualify for derecognition. The Company’s financial liabilities measured at amortized cost are classified as ‘trade and other payables’, ‘borrowings’ and ‘other financial liabilities’ in the financial statements. For cases not qualifying for derecognition, the transferred asset continues to be recognized and a financial liability is measured as the consideration received. Financial liabilities measured at amortized cost are included in non-current liabilities, except for liabilities with maturities of less than 12 months as of the end of the reporting period, which are classified as current liabilities.

(2) Recognition and measurement

Regular purchases and sales of financial assets are recognized on the trade date (the date on which the Company commits to purchase or sell the assets). Investments are initially recognized at fair value plus transaction costs for all financial assets not carried at fair value through profit or loss. Financial assets carried at fair value through profit or losses are initially recognized at fair value, and transaction costs are expensed in the statement of income. Available-for-sale financial assets and financial assets at fair value through profit or loss are subsequently carried at fair value. Loans and receivables are subsequently carried at amortized cost using the effective interest rate method.

Gains or losses arising from changes in the fair value of the financial assets and liabilities at fair value through profit or loss are presented in the statement of income within ‘finance income (costs)’ in the period in which they arise. The Company recognizes a dividend income from financial assets at fair value through profit or loss in the statement of income when the Company’s right to receive payments is established.

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 recognized at cost. Other than these investments, all available-for-sale financial assets are measured at fair value.

Changes in the fair value of monetary and non-monetary securities classified as available-for-sale are recognized in other comprehensive income. When securities classified as available-for-sale are sold or impaired, the accumulated fair value adjustments recognized in equity are reported in the statement of income as ‘finance income(costs)’. However, in case a subsidiary is engaged in the financial industry, the accumulated fair value adjustments recognized in equity are recognized as ‘operating income.’

Interest on available-for-sale financial assets calculated using the effective interest method is recognized in the statement of income as part of ‘finance income’. Dividends on available-for-sale equity instruments are recognized in the statement of income as part of ‘finance income’ when the Company’s right to receive payments is established. However, in case a subsidiary is engaged in the financial industry, the realized accumulated fair value adjustment, interest and dividends on available-for-sale are recognized as ‘operating income and expense’ in the statement of income.

(3) Offsetting financial instruments

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

(4) Derecognition of financial assets

Financial assets are derecognized when the contractual rights to receive cash from the investments have expired or have been transferred, and the Company has substantially transferred all

F-22

risks and rewards of ownership or when the risk and rewards of ownership of transferred assets have not been substantially retained or transferred and the Company has not retained control over these assets.

2.7    Impairment of Financial Assets

(1) Assets carried at amortized cost

The Company assesses at the end of each reporting period whether there is objective evidence that a financial asset or a group of financial assets is impaired. A financial asset or a group of financial assets is impaired and impairment losses are incurred only if there is objective evidence of impairment as a result of one or more events that occurred after the initial recognition of the asset (a ‘loss event’) and that loss event (or events) has an impact on the estimated future cash flows of the financial asset or a group of financial assets that can be reliably estimated.

The criteria that the Company uses to determine that there is objective evidence of an impairment loss include:

• Significant financial difficulty of the issuer or obligor;

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

• The Company, for economic or legal reasons relating to the borrower’s financial difficulty, granting to the borrower a concession that the lender would not otherwise consider;

• It becomes probable that the borrower will enter bankruptcy or other financial reorganisation;

• 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 portfolio of financial assets since the initial recognition of those assets, although the decrease cannot yet be identified with the individual financial assets in the portfolio, including:

• Adverse changes in the payment status of borrowers in the portfolio;

• National or local economic conditions that correlate with defaults on the assets in the portfolio.

The amount of the loss is measured as the difference between the asset’s carrying amount and the present value of estimated future cash flows (excluding future credit losses that have not been incurred) discounted at the financial asset’s original effective interest rate. The carrying amount of the asset is reduced and the amount of the loss is recognized in the statement of income. If a financial asset has a variable interest rate, the discount rate for measuring any impairment loss is the current effective interest rate determined under the contract. The Company may measure impairment of the financial instruments on the basis of an instrument’s fair value using an observable market price.

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 debtor’s credit rating), the reversal of the previously recognized impairment loss is recognized in the statement of income.

F-23

(2) Assets classified as available-for-sale

The Company assesses at the end of each reporting period whether there is objective evidence that a financial asset or a group of financial assets is impaired. For debt securities, the Company uses the criteria referred to (1) above. In the case of equity investments classified as available-for-sale, a significant or prolonged decline in the fair value of the security below its cost is also evidence that the asset is impaired. If any such evidence exists for available-for-sale financial assets, the cumulative loss—measured as the difference between the acquisition cost and the current fair value, less any impairment loss on that financial asset previously recognized in profit or loss—is removed from equity and recognized in the statement of income. Impairment losses recognized in the statement of income on equity instruments are not reversed through the statement of income. 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 through the statement of income.

2.8    Derivative Financial Instruments

Derivatives are initially recognized at fair value on the date a derivative contract is entered into and are subsequently re-measured at their fair value. The method of recognizing the resulting gain or loss depends on whether the derivative is designated as a hedging instrument, and if so, the nature of the item being hedged. The gain or loss relating to derivative financial instruments which are classified as financial instruments at fair value through profit or loss is recognized as finance income (costs) in the statement of income.

If the Company uses a valuation technique that incorporates data not obtained from observable markets for the fair value at initial recognition of the financial instrument, there may be a difference between the transaction price and the amount determined using that valuation technique (Day 1 profit and loss). In these circumstances, the fair value of the financial instrument is recognized as the transaction price and the difference is amortized by using the straight-line method over the life of the financial instrument. If the fair value of the financial instrument is subsequently determined using observable market inputs, the remaining deferred amount is recognized in profit or loss in the statement of income.

The Company designates certain derivatives as either:

• Hedges of the fair value of a recognized asset or liability or a firm commitment (fair value hedge); or

• Hedges of a particular risk associated with a recognized asset or liability on a highly probable forecast transaction (cash flow hedge)

The Company documents at the inception of the transaction, the relationship between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking various hedging transactions. The Company also documents its assessment, both at hedge inception and on an ongoing basis, of whether the derivatives that are used in hedging transactions are highly effective in offsetting changes on fair values or cash flows of hedged items.

The fair value and changes in the fair value of derivatives for hedge recorded as other comprehensive income are described in Note 8. The full fair value of a hedging item is more than 12 months and as a current asset or liability when the remaining maturity of the hedged item is less than 12 months. Trading derivatives are classified as a current asset or liability.

F-24

(1) Fair value hedge

Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recorded as ‘finance income(costs)’ in the income statement, together with any changes in the fair value of the hedged asset or liability that are attributable to the hedged risk.

If the hedge no longer meets the criteria for hedge accounting, the adjustment to the carrying amount of a hedged item for which the effective interest method is used is amortized to profit or loss over the period to maturity.

(2) Cash flow hedge

The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is hedges is recognized in other comprehensive income. The gain of loss relating to the ineffective portion is recognized immediately as finance income (costs) in the statement of income.

Amounts accumulated in equity are reclassified to profit or loss in the periods when the hedged item affects profit or loss (for example, when the forecast sale that is hedged takes place). The gain or loss relating to the effective portion of interest rate swaps hedging variable rate foreign borrowings is recognized in other comprehensive income. The gain or loss relating to the ineffective portion is recognized as financial income in the statement of income.

When a hedging instrument expires or is sold, or when a hedge no longer meets the criteria for hedge accounting, any cumulative gain or loss existing in equity at that time remains in equity and is recognized when the forecast transaction is ultimately recognized in the income statement. When a forecast transaction is no longer expected to occur, the cumulative gain or loss that was reported in equity is immediately reclassified as finance income (costs) in the statement of income.

2.9    Trade Receivables

Trade receivables are amounts due from customers for merchandise sold or services performed in the ordinary course of business. If collection is expected in one year or less, they are classified as current assets. If not, they are presented as non-current assets. Trade receivables are recognized initially at fair value and subsequently measured at amortized cost using the effective interest method, less allowance for doubtful accounts.

2.10    Inventories

Inventories are stated at the lower of cost and net realizable value. Cost is determined using the weighted-average method, except for inventories in-transit which is determined using the specific identification method. Net realizable value is the estimated selling price in the ordinary course of business, less applicable selling expenses.

2.11    Property and Equipment

All property and equipment are stated at historical cost less depreciation. Historical cost includes expenditure that is directly attributed to the acquisition of the items. However, in accordance with IFRS 1, First-time Adoption of IFRS, the Company measured certain buildings and telecommunications equipment at fair value at the date of transition to IFRS and the fair value is used as their deemed cost at that date.

F-25

Subsequent costs are included in the asset’s carrying amount or recognized as a separate asset, as appropriate, only when 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. All other repairs and maintenance are charged to the statement of income during the financial period in which they are incurred.

Land is not depreciated. Depreciation on other assets is calculated using the straight-line method to allocate their cost to their residual values over their estimated useful lives, as follows:

	Estimated Useful Lives
Buildings	5 – 40 years
Structures	5 – 40 years
Machinery and equipment	3 – 40 years
(Telecommunications equipment and others) Others
Vehicles	4 – 6 years
Tools	4 – 6 years
Office equipment	4 – 6 years

The assets’ residual values and useful lives are reviewed, and adjusted if appropriate, at the end of each reporting period. An asset’s carrying amount is written down immediately to its recoverable amount if the asset’s carrying amount is greater than its estimated recoverable amount. Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are recognized within ‘operating income (expenses)’ in the statement of income.

2.12    Investment Property

Investment property is held to earn rentals or for capital appreciation or both. Investment property is measured initially at its cost including transaction costs incurred in acquiring the asset. After recognition as an asset, investment property is carried at its cost less any accumulated depreciation and impairment losses.

Subsequent costs are included in the asset’s carrying amount or recognized as a separate asset, as appropriate, only when 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. All other repairs and maintenance are charged to the statement of income during the financial period in which they are incurred.

Land held for investment is not depreciated. Investment property, except for land, is depreciated using the straight-line method over their estimated useful lives.

The depreciation method, the residual value and the useful life of an asset are reviewed at least at the end of each reporting period and, if management judges that previous estimates should be adjusted, the change is accounted for as a change in an accounting estimate.

2.13    Intangible Assets

(1) Goodwill

Goodwill is measured as explained in Note 2.2 (1) and goodwill arising from acquisition of subsidiaries and business are included in intangible assets. Goodwill is tested annually for impairment and carried at cost less accumulated impairment losses. Impairment losses on goodwill are not reversed. The calculation of the gains and losses on the disposal of an entity include the carrying amount of goodwill relating to the entity sold.

F-26

For the purpose of impairment testing, goodwill acquired in a business combination is allocated to each of the acquirer’s cash-generating units, or groups of cash-generating units (“CGU”), that is expected to benefit from the synergies of the combination. Goodwill is monitored at the operating segment level.

Goodwill impairment reviews are undertaken annually or more frequently if events or changes in circumstances indicate a potential impairment. The carrying value of goodwill is compared to the recoverable amount, which is the higher of value in use and the fair value less costs to sell. Any impairment is recognized immediately as an expense and is not subsequently reversed.

(2) Intangible assets except goodwill

Separately acquired Intangible assets except for goodwill are shown at historical cost. These assets have definite useful lives and are carried at historical cost less accumulated amortization. Amortization is calculated using the straight-line method to allocate the cost of assets over their estimated useful lives. However, facility usage rights (condominium membership and golf membership) and broadcast license are regarded as intangible assets with indefinite useful life and not amortized, because there is no foreseeable limit to the period over which the asset is expected to generate net cash inflows for the Company.

The useful life of an asset with indefinite useful life is reviewed each period to determine whether events and circumstances continue to support the indefinite useful life assessment for that asset. If management judges that previous estimates should be adjusted, the change is accounted for as a change in an accounting estimate. The depreciation method and useful life of an asset with definite useful life are reviewed at the end of each reporting period.

The estimated useful life used for amortizing intangible assets is as follows:

	Estimated Useful Lives
Development costs	5 – 6 years
Goodwill	Unlimited useful life
Software	2 – 10 years
Industrial property rights	2 – 10 years
Frequency usage rights	5.75 – 13 years
Others 1	3 – 50 years

1 Facility usage rights (condominium membership and golf membership) and broadcast license included in others are classified as intangible assets with indefinite useful life.

(3) Research and development costs

Expenditure on research is recognized as an expense as incurred. If the expense as incurred that is identifiable and when the probable future economic benefits are expected, the cost for the new merchandises and technology is recognized as intangible assets when all the following criteria are met:

• It is technically feasible to complete the intangible asset so that it will be available for use;

• Management intends to complete the intangible asset and use or sell it;

• There is the ability to use or sell the intangible asset;

• It can be demonstrated how the intangible asset will generate probable future economic benefits;

F-27

• Adequate technical, financial and other resources to complete the development and to use or sell the intangible asset are available; and

• The expenditure attributable to the intangible asset during its development can be reliably measured

Other development expenditures that do not meet these criteria are recognized as expenses as incurred. Development costs previously recognized as an expense are not recognized as an asset in a subsequent period. Capitalized development costs, which are stated as intangible assets, are amortized using the straight-line method when the assets are available for use and are tested for impairment.

2.14    Borrowing Costs

General and specific borrowing costs directly attributable to the acquisition, construction or production of qualifying assets, which are assets that necessarily take a substantial period of time to get ready for their intended use or sale, are added to the cost of those assets, until such time as the assets are substantially ready for their intended use or sale. Investment income earned on the temporary investment of specific borrowings pending their expenditure on qualifying assets is deducted from the borrowing costs eligible for capitalization. All other borrowing costs are recognized in profit or loss in the period in which they are incurred.

2.15    Government Grants

Grants from a government are recognized as operating income at their fair value where there is a reasonable assurance that the grant will be received and the Company will comply with all attached conditions.

Government grants relating to costs are deferred and recognized in the statement of income over the period necessary to match them with the costs that they are intended to compensate. Government grants relating to property and equipment are deferred and are credited to the statement of income on a straight-line basis over the expected lives of the related assets.

2.16    Impairment of Non-Financial Assets

Assets that have an indefinite useful life such as goodwill are not subject to amortization and are tested annually for impairment. Assets that are subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognized for the amount by which the asset’s carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset’s fair value less costs to sell and its value in use. For the purposes of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash flows (cash-generating units). Non-financial assets other than goodwill that suffered impairment are reviewed for possible reversal of the impairment at each reporting date.

2.17    Trade Payables

Trade payables are obligations to pay for goods or services that have been acquired in the ordinary course of business from suppliers. Trade payables are classified as current liabilities if payment is due within one year. If not, they are presented as non-current liabilities. Trade payables are initially recognized at fair value and subsequently measured at amortized cost using the effective interest method.

F-28

2.18    Financial guarantee contracts

A financial guarantee contract is a contract that requires the issuer to make specified payments to reimburse the holder for a loss it incurs because a specified debtor fails to make payment when due in accordance with the original or modified terms of a debt instrument. Financial guarantee is initially measured at fair value on the date the guarantee was given. Subsequent to initial recognition, the Company’s liabilities under such guarantees are measured at the higher of the amounts below. Any increase in the liability relating to guarantees is reported as other financial liabilities:

• The amounts determined in accordance with IAS 37 Provisions Contingent Liabilities and Contingent Assets, or

• The amounts initially recognized less the accumulated amortization accordance with IAS 18 Revenue

2.19    Borrowings

Borrowings are recognized initially at fair value, net of transaction costs incurred. Borrowings are subsequently carried at amortized cost; any difference between the proceeds (net of transaction costs) and the redemption value is recognized in the statement of income over the period of the borrowings using the effective interest method. However, in case a subsidiary is engaged in the financial industry, the interest expenses are recognized as operating expenses since it is considered as a main business activity of the subsidiary.

The Company classifies the liability as current when it does not have an unconditional right to defer its settlement for at least 12 months after the reporting date.

2.20    Compound Financial Instruments

Compound financial instruments issued by the Company consist of convertible bond that can be converted to share capital at the option of the holder, and the number of shares to be issued does not vary with changes in their fair value.

The liability component of a compound financial instrument is recognized initially at the fair value of a similar liability that does not have an equity conversion option. The equity component is recognized initially at the difference between the fair value of the compound financial instrument as a whole and the fair value of the liability component. Any directly attributable transaction costs are allocated to the liability and equity components in proportion to their initial carrying amounts.

Subsequent to initial recognition, the liability component of a compound financial instrument is measured at amortized cost using the effective interest method. The equity component of a compound financial instrument is not re-measured subsequent to initial recognition except on conversion or expiry.

2.21    Employee Benefits

(1) Retirement benefit liabilities

The liability recognized in the statement of financial position in respect of the defined benefit pension plan is the present value of the defined benefit obligation at the end of the reporting period less the fair value of plan assets. The defined benefit obligation is calculated annually using the projected unit credit method. The present value of the defined benefit obligation is determined by

F-29

discounting the estimated future cash outflows using interest rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be paid, and that have terms to maturity approximating the terms of the related pension liability.

Actuarial gains and losses arising from experience adjustments and changes in actuarial assumptions are charged or credited to equity in other comprehensive income in the period in which they arise. Past-service costs are recognized immediately in income, while costs are amortized over the vesting period.

(2) Defined contribution plan

A defined contribution plan is a pension plan under which the Company pays fixed contributions into a separate entity. The Company has no legal or constructive obligations to pay further contributions if the fund does not hold sufficient assets to pay all employees the benefits relating to employee service in the current and prior periods. For defined contribution plans, the Company pays contributions to publicly or privately administered pension insurance plans on a mandatory, contractual or voluntary basis. The Company has no further payment obligations once the contributions have been paid. The contributions are recognized as employee benefit expense when they are due. Prepaid contributions are recognized as an asset to the extent that a cash refund or a reduction in the future payments is available.

(3) Termination benefits

Termination benefits are payable when employment is terminated by the Company before the normal retirement date, or whenever an employee accepts voluntary redundancy in exchange for these benefits. The Company recognizes termination benefits when it is demonstrably committed to either: terminating the employment of current employees according to a detailed formal plan without possibility of withdrawal; or providing termination benefits as a result of an offer made to encourage voluntary redundancy.

2.22    Share-based payments

The Controlling Company operates share-based compensation plans, under which the Controlling Company receives services from employees as consideration for equity instruments (options) of the Controlling Company. The fair value of the employee services received in exchange for the grant of the options is recognized as a compensation expense in the statement of income over the vesting period.

2.23    Provisions

Provisions are recognized when the Company has a present legal or constructive obligation as a result of past events and an outflow of resources required to settle the obligation is probable and can be reliably estimated. Provisions are not recognized for future operating losses.

Provisions are measured at the present value of the expenditures expected to be required to settle the obligation. The increase in the provisions due to passage of time is recognized as an interest expense.

2.24    Leases

A lease is an agreement, whereby the lessor conveys to the lessee, in return for a payment or series of payments, the right to use an asset for an agreed period of time

F-30

(1) The Company as the Lessee

Leases in which a significant portion of the risks and rewards of ownership are retained by the lessor are classified as operating leases. Payments made under operating leases are charged to the statement of income on a straight-line basis over the period of the lease.

Lease of property and equipment where the lessee has substantially all the risks and rewards of ownership are classified as finance leases. Finance leases are capitalized at the lease’s commencement at the lower of the fair value of the leased property and the present value of the minimum lease payments. Each lease payment is allocated between the liability and finance charges so as to achieve a constant rate on the outstanding balance. The corresponding rental obligations, net of finance charges, are included in the finance lease liabilities.

The interest element of the finance cost is charged to the statement of income over the lease period so as to produce a constant periodic rate of interest on the remaining balance of the liability for each period. The property, plant and equipment acquired under finance leases are depreciated over the shorter of the useful life of the asset and the lease term.

(2) The Company as the Lessor

For finance leases, lease receivables are recognized at the amount equivalent to the net investment in the lease asset. The Company recognizes interest income, which is calculated for net finance lease receivable based on effective interest rate. Lease income from operating leases shall be recognized on a straight-line basis over the lease term. Initial direct costs incurred by lessors in negotiating and arranging operating leases shall be added to the carrying amount of the lease asset and recognized as the expenses over the lease term corresponding to the lease income.

2.25    Dividend Distribution

Dividend distribution to the Company’s shareholders is recognized as a liability in the financial statements in the period in which the dividends are approved by the Company’s shareholders.

2.26    Capital Stock

Common stocks are classified as equity.

Where the Controlling Company purchases its own equity share capital, the consideration paid, including any directly attributable incremental costs, is deducted from equity attributable to the Controlling Company’s equity holders until the stocks are cancelled or reissued. Where such shares are subsequently reissued, any consideration received is included in equity attributable to the Controlling Company’s equity holders.

2.27    Revenue Recognition

Revenue comprises the fair value of the consideration received or receivable for the sales of goods and services in the ordinary course of the Company’s activities. Revenue is shown net of value-added tax, returns, rebates and discounts and after eliminating sales within the Company.

The Company recognizes revenue when the amount of revenue can be reliably measured, it is probable that future economic benefits will flow to the entity and when specific criteria have been met for each of the Company’s activities as described below. The Company bases its estimates on historical results, taking into consideration the type of customer, the type of transaction and the specifics of each arrangement.

F-31

(1) Sales of Services

When providing interconnection or telecommunications service to a customer based on service plans, the related revenue is recognized at the time service is provided. If the customer uses the telecommunications equipment according to the service plans, the related revenue is recognized on straight-line basis over the contract period. Revenue related to the other telecommunications services is recognized when the service is provided to the customer.

For other services, when the outcome of a transaction involving the rendering of services can be estimated reliably, revenue associated with such a transaction is recognized by reference to the stage of performance of the services. When the outcome of the transaction involving the rendering of services cannot be estimated reliably, revenue is recognized only to the extent of the expenses recognized that are recoverable.

Total consideration for combined services is allocated to each service in proportion to its fair value and the allocated amount is recognized as revenue according to revenue recognition policy for the service.

(2) Sales of goods

Sales of goods such as selling handsets are recognized when the Company has delivered products to the customer. Delivery does not occur until the products have been shipped to the specified location, the risks of obsolescence and loss have been transferred to the customer, and either the customer has accepted the products in accordance with the sales contract, the acceptance provisions have lapsed, or the Company has objective evidence that all criteria for acceptance have been satisfied.

(3) Interest income

Interest income is recognized using the effective interest method. When a loan and receivable is impaired, the Company reduces the carrying amount to its recoverable amount and continues unwinding the discount as interest income. Interest income on impaired receivables is recognized using the original effective interest rate.

(4) Commission fees

Commission fees related to credit card business recognized when it is probable that future economic benefits will flow to the entity and these benefits can be reliably measured. Revenues from acquiree fee, agent fee, optional service fees, member service fees and credit card service charge are measured at the fair value of the consideration received and recognized on a accrual basis.

(5) Royalty income

Royalty income is recognized on an accrual basis in accordance with the substance of the relevant agreements.

(6) Dividend income

Dividend income is recognized when the right to receive payment is established.

F-32

(7) Customer loyalty program

The Company operates a customer loyalty program in which customers are granted rewards points. The granted reward is recognized as a separately identifiable component of the sale transaction (initial sale transaction) that grants the reward. The fair value of consideration to give or given for the initial sale is allocated to the reward points and remaining of initial sale, and the consideration allocated to the reward points is measured based on the fair value of reward in exchange of reward points, which is the fair value of reward points considered the proportion of reward points that are not expected to be redeemed. Revenue from the award credits is recognized when it is redeemed.

2.28    Current and Deferred Income Tax

The tax expense for the period consists of current and deferred tax. Tax is recognized in the statement of income, except to the extent that it relates to items recognized in other comprehensive income or directly in equity. In this exception, the tax is also recognized in other comprehensive income or directly in equity, respectively.

The current income tax charge is calculated on the basis of the tax laws enacted or substantially enacted at the reporting date in the countries where the Company operates and generates taxable income. Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation. It establishes provisions where appropriate on the basis of amounts expected to be paid to the tax authorities.

Deferred income tax is recognized, using the liability method, on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the financial statements. However, the deferred income tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither accounting nor taxable profit nor loss. Deferred income tax is determined using tax rates and laws that have been enacted or substantially enacted by the end of the reporting period and are expected to apply when the related deferred income tax asset is realized or the deferred income tax liability is settled.

Deferred income tax assets are recognized only to the extent that it is probable that future taxable profit will be available against which the temporary differences can be utilized.

Deferred income tax liabilities are provided on temporary differences arising on investments in subsidiaries and associates, except where the timing of the reversal of the temporary difference is controlled by the Company and it is probable that the temporary difference will not reverse in the foreseeable future. Deferred income tax is recognized only 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.

Deferred income tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets against current tax liabilities and when the deferred income taxes assets and liabilities relate to income taxes levied by the same taxation authority on either the same taxable entity or different taxable entities.

2.29    Deferred Loan Fees and Costs

Loan origination fees in relation to loan origination process such as upfront fee, are deferred and amortized over the life of the loan as an adjustment to the yield of the loan using the effective interest rate method. Loan origination costs, which relates to loan origination activities such as

F-33

commissions to brokers, are deferred and amortized over the life of the loan as an adjustment to the yield of the loan, using the effective interest rate method, if the future economic benefit related costs incurred can be matched with each loan.

In addition, the amortization of the deferred loan origination fees on costs is offset and the net amounts are presented in the consolidated statement of financial position.

2.30    Non-current Assets Held for Sale and Discontinued Operations

Non-current assets (or disposal groups) are classified as ‘assets and liabilities classified as held for sale’ (or ‘groups classified as held for sale’) when their carrying amount is to be recovered principally through a sale transaction and a sale is considered highly probable. They are stated at the lower of carrying amount or fair value less costs to sell.

When a component of the Company representing a separate major line of business or geographical area of operation has been disposed of, or is subject to a sale plan involving loss of control of a subsidiary, the Company discloses in the statement of income the post-tax profit or loss of discontinued operations and the post-tax gain or loss recognized on the measurement to fair value less costs to sell or on the disposal of the assets or group to be sold constituting the discontinued operation. The net cash flows attributable to the operating, investing and financing activities of discontinued operations are presented in the notes to the financial statements (Note 36).

2.31    Approval of Issuance of the Financial Statements

The issuance of the Company’s consolidated financial statements was approved by the directors on April 29, 2013.

2.32    US Dollar Convenience Translation

The December 31, 2012 consolidated financial statements are expressed in Korean Won and have been translated into U.S. dollars at the rate of ￦1,071.1 to US$1, the market average exchange rate announced by Seoul Money Brokerage Services, Ltd. and in effect on December 31, 2012, solely for the convenience of the reader. These translations should not be construed as a representation that any or all of the amounts shown could be converted into U.S. dollars at this or any other rate.

3.    Critical Accounting Estimates and Assumptions

The Company makes estimates and assumptions concerning the future. Estimates and assumptions are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. The resulting accounting estimates will, by definition, seldom equal the related actual results. The estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are addressed below.

3.1    Estimated Impairment of Goodwill

The Company tests annually whether goodwill has suffered any impairment in accordance with the accounting policy stated in Note 2.13. The recoverable amounts of cash-generating units have been determined based on value-in-use calculations. These calculations require the use of estimates (Note 13).

F-34

3.2    Income Taxes

Current and deferred income tax are determined using tax rates and laws that have been enacted or substantially enacted by the end of the reporting period and are expected to apply when the related deferred income tax asset is realized or the deferred income tax liability is settled. Where the final tax outcome of these matters is different from the amounts that were initially recorded, such differences will impact the current and deferred income tax assets and liabilities in the period in which such determination is made.

3.3    Fair Value of Financial Instruments

The fair value of financial instruments that are not traded in an active market is determined by using valuation techniques. The Company uses its judgment to select a variety of methods and makes assumptions that are mainly based on market conditions existing at the end of each reporting period.

3.4    Allowance for Doubtful Accounts

The Company recognizes provisions for accounting of estimated loss in customers’ insolvency. When the allowance for doubtful accounts is estimated, it is based on the aging analysis of trade receivables balances, incurred loss experience, customers’ credit rates and changes of payment terms. If the customer’s financial position becomes worse, the actual loss amount will be increased more than the estimated.

3.5    Post-employment Benefit Liabilities

The present value of the post-employment benefit liabilities depends on a number of factors that are determined on an actuarial basis using a number of assumptions. The assumptions used in determining the defined benefit obligation include the discount rate. Any changes in these assumptions will impact the carrying amount of the defined benefit obligation.

The Company determines the appropriate discount rate at the end of each reporting period. This is the interest rate that is used to determine the present value of estimated future cash outflows expected to be required to settle the defined benefit obligation. In determining the appropriate discount rate, the Company considers the interest rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be paid, and that have terms to maturity approximating the terms of the related liability. Other key assumptions for defined benefit obligation are based in part on current market conditions. The related information is disclosed in Note 18.

3.6    Deferred Revenue

Service installation fees and initial subscription fees related to activation of service are deferred and recognized as revenue over the expected terms of customer relationships. The estimate of expected terms of customer relationship is based on the historical rate. If management’s estimation is amended, it may cause significant differences in the timing of revenue recognition and amount recognized.

3.7    Provisions

As described in Note 17, the Company records provisions for litigation, assets retirement obligations and others as of the end of the reporting period. The provisions are estimated based on the factors such as the historical experiences.

Diluted earnings per share from discontinued operations (in Korean won)	￦	33	￦	681	￦	(122	)

Diluted earnings per share from discontinued operations is calculated by dividing adjusted profit from discontinued operations attributable to equity holders of the Company by the sum of the number of common stocks and dilutive potential common stocks. Certain other share-based payments have no dilutive effect and are excluded from the calculation of diluted earnings per share from discontinued operations.

Diluted earnings per share is calculated by adjusting the weighted average number of common stocks outstanding to assume conversion of all dilutive potential common stocks. The Company has dilutive potential common stocks from stock options.

Telecom & Convergence Customer Group	Telecommunication service to mass customers and convergence business
Global & Enterprise Group	Telecommunication service to global market and enterprise customers and data service
Finance/Rental Business Group	Credit card, loan, lease and others
Others	Security service, and others

In 2012, the Company restructured its organization, thereby aligning its operation to effectively cope with the challenging business environment. As a result, the Company has redefined its segments to four reporting segments: the Telecommunication & Convergence Group/Customer, the Global & Enterprise Group, Finance/Rental and others as of December 31, 2012 while the Company had three reporting segments as of December 31, 2011.

Details of each segment for the years ended December 31, 2010, 2011 and 2012, are as follows:

1 Due to the limited availability of necessary information, which mainly resulted from the implementation of the new ERP system in 2012, the Company was not able to produce all of the information needed to recast full segment information for 2010 except for the information of the operating revenue by segment, which the Company prepared by applying the reasonable and systematic allocation criteria.

34.    Financial risk management

(1) Financial risk factors

The Company’s activities expose itself to a variety of financial risks such as changes in foreign exchange rates, interest rates and market prices arising from future commercial transactions and recognized assets and liabilities. The Company’s financial risk management is focused on controlling these risks in its operating and financing activities. The Company uses derivatives to hedge certain financial risk exposures such as fair value risk and cash flow risk.

The Company’s financial policy is set up in the long-term perspective and annually reported to the Board of Directors. The financial risk management is carried out by the Value Management Office, which identifies, evaluates and hedges financial risks. The treasury department in the Value Management Office considers various market conditions to estimate the effect from the market changes.

1) Market risk

The Company’s market risk management focuses on controlling the extent of exposure to the risk in order to minimize revenue volatility. Market risk is a risk that decreases value or profit of the Company’s portfolio due to changes in market interest rate, foreign exchange rate and other factors.

(i) Sensitivity analysis

Sensitivity analysis is performed for each type of market risk to which the Company is exposed. Reasonably possible changes in the relevant risk variable such as prevailing market interest rates, currency rates, equity prices or commodity prices are estimated and if the rate of change in the underlying risk variable is stable, the Company does not alter the chosen reasonably possible change in the risk variable. The reasonably possible change does not include remote or ‘worst case’ scenarios or ‘stress tests’.

(ii) Foreign exchange risk

The Company is exposed to foreign exchange risk arising from operating, investing and financing activities. Foreign exchange risk is managed within the range of the possible effect on the Company’s cash flows. Foreign exchange risk unaffecting the Company’s cash flows is not hedged but can be hedged at a particular situation.

As of December 31, 2010, 2011 and 2012, if the foreign exchange rate had strengthened/weakened by 10% with all other variables held constant, the effects on profit before income tax and shareholders’ equity would have been as follows:

(in millions of Korean won)	Fluctuation of foreign exchange  rate			Income before tax			Shareholders’ equity
2010.12.31		+10	%	￦	(60,833	)	￦	(45,933	)
		-10	%		60,833			45,933
2011.12.31		+10	%		(57,174	)		(50,471	)
		-10	%		57,174			50,471
2012.12.31		+10	%		(65,189	)		(52,646	)
		-10	%		65,189			52,646

The above analysis is a simple sensitivity analysis which assumes that all the variables other than foreign exchange rates are held constant. Therefore, the analysis does not reflect any correlation between foreign exchange rates and other variables, nor the management’s decision to decrease the risk.

(iii) Price risk

As of December 31, 2010, 2011 and 2012, the Company is exposed to equity securities price risk because the securities held by the Company are traded in active markets. If the market prices had increased/decreased by 10% with all other variables held constant, the effects on profit before income tax and shareholders’ equity would have been as follows:

(in millions of Korean won)	Fluctuation of price			Income before tax		Shareholders’ equity
2010.12.31		+10	%	￦	—	￦	1,914
		-10	%		—		(1,914	)
2011.12.31		+10	%		—		10,118
		-10	%		—		(10,118	)
2012.12.31		+10	%		—		4,916
		-10	%		—		(4,916	)

The analysis is based on the assumption that the equity index had increased/decreased by 10% with all other variables held constant and all the Company’s marketable equity instruments had moved according to the historical correlation with the index.

(iv) Cashflow and fair value interest rate risk

The Company’s interest rate risk arises from liabilities in foreign currency such as foreign currency bonds payable. Bonds payable in foreign currency issued at variable rates expose the Company to cash flow interest rate risk which is partially offset by swap transactions. Bonds payable and borrowings issued at fixed rates expose the Company to fair value interest rate risk. The Company sets the policy and operates to minimize the uncertainty of the changes in interest rates and financial costs.

As of December 31, 2010, 2011 and 2012, if the market interest rate had increased/decreased by 100bp with other variables held constant, the effects on profit before income tax and shareholders’ equity would be as follows:

(In millions of Korean won)	Fluctuation of interest rate		Income before tax			Shareholders’ equity
2010.12.31		+ 100 bp	￦	(660	)	￦	(3,618	)
		- 100 bp		(17,293	)		(14,603	)
2011.12.31		+ 100 bp		(1,488	)		(345	)
		- 100 bp		(13,108	)		(14,445	)
2012.12.31		+ 100 bp		(458	)		(264	)
		- 100 bp		(5,204	)		(5,465	)

F-80

The above analysis is a simple sensitivity analysis which assumes that all the variables other than market interest rates are held constant. Therefore, the analysis does not reflect any correlation between market interest rates and other variables, nor the management’s decision to decrease the risk.

2) Credit risk

Credit risk is managed on the Company basis with the purpose of minimizing financial loss. Credit risk arises from the normal transactions and investing activities, where clients or other party fails to discharge an obligation on contract conditions. To manage credit risk, the Company considers the counterparty’s credit based on the counterparty’s financial conditions, default history and other important factors.

Credit risk arises from cash and cash equivalents, derivative financial instruments and deposits with banks and financial institutions, as well as outstanding receivables. To minimize such risk, only the financial institutions with strong credit ratings are accepted.

As of December 31, 2011 and 2012, maximum exposure to credit risk that are not considered of value of collateral held regarding financial instrument are as follows.

(2) Disclosure of capital management

The Company’s objectives when managing capital are to safeguard the Company’s ability to continue as a going concern in order to provide returns for shareholders and benefits for other shareholders and to maintain an optimal capital structure to reduce the cost of capital.

The Company’s capital structure consists of liabilities including borrowings, cash and cash equivalents, and shareholders’ equity. The treasury department monitors the Company’s capital structure and considers cost of capital and risks related each capital component.

F-82

The debt-to-equity ratios as of December 31, 2011 and 2012, are as follows:

(in millions of Korean won)	2011			2012
Total liabilities	￦	19,547,600		￦	21,314,987
Total equity		12,537,809			13,164,512
Debt-to-equity ratio		156	%		162	%

The Company manages capital on the basis of the gearing ratio. This ratio is calculated as net debt divided by total capital. Net debt is calculated as total borrowings less cash and cash equivalents. Total capital is calculated as ‘equity’ in the statement of financial position plus net debt.

The gearing ratios as of December 31, 2011 and 2012, are as follows:

(in millions of Korean won, %)	2011			2012

(3) Fair value estimation

The table below analyzes financial instruments carried at fair value, by valuation method. The different levels have been defined as follows:

• Quoted prices (unadjusted) in active markets for identical assets or liabilities (level 1)

• Inputs other than quoted prices included within level 1 that are observable for the asset or liability, either directly (that is, as prices) or indirectly (that is, derived from prices) (level 2)

• Inputs for the asset or liability that are not based on observable market data (that is, unobservable inputs) (level 3)

The following table presents the Company’s assets and liabilities that are measured at fair value as of December 31, 2011 and 2012:

Total	￦	—	￦	112,666	￦	3,153	￦	115,819

The fair value of financial instruments traded in active markets is based on quoted market prices at the date of the end of reporting period. A market is regarded as active if quoted prices are readily and regularly available from an exchange, dealer, broker, an entity within the same industry, pricing service, or regulatory agency, and those represent actual and regularly occurring market transactions on an arm’s length basis. The quoted market price used for financial assets held by the Company is the bid price. These instruments are included in level 1. Instruments included in level 1 comprise listed equity investments classified as available-for-sale.

The fair value of financial instruments that are not traded in an active market (for example, over-the-counter derivatives) is determined by using valuation techniques. These valuation techniques maximize the use of observable market data where it is available and rely as little as possible on entity specific estimates. If all significant inputs required to fair value of an instrument are observable, the instrument is included in level 2.

If one or more of the significant inputs are not based on observable market data, the instrument is included in level 3.

The changes of the financial instrument included in Level 3 for the year ended December 31, 2012, are as follows:

(in millions of Korean won)	Available-for-sale financial assets			Derivative financial liabilities			Financial liability at fair value through profit or loss
Beginning	￦	134,346		￦	2,258		￦	—

Others		99,544		67,733
Total	￦	159,897	￦	143,360

The range of cashflow estimates is significant and the probabilities of the various estimates cannot be reasonably assessed and therefore these instruments are measured at cost.

The Company does not have any plans to dispose of the above-mentioned equities instruments in the near future. These instruments will be measured at fair value when the Company can develop a reliable estimate of the fair value.

35.    Business Combination

(1) KT Rental Co., Ltd.

On July 31, 2012, Hana Daetoo Securities Co., Ltd. and other investors acquired 4,126,932 shares(42%) of KT Rental’s common stocks from Korea Rental Investment, Inc.(“KRI”) which is second largest shareholder of KT Rental. As a result, the restriction on controlling power of the Controlling Company under the shareholders’ agreement between the Controlling Company and KRI was resolved, and KT rental was included in the consolidated subsidiaries. These transactions were accounted for in accordance with Korean IFRS 1103, Business Combinations.

As a result of applying acquisition method, the Company recognized goodwill of ￦131,426 million, which is the excess of total consideration transferred over the fair value of the net assets at the acquisition date. The fair value of the net assets at the acquisition date includes the identifiable intangible assets such as customer relationship, which was not previously recognized in the subsidiary’s financial statements.

(2) KT Skylife Co., Ltd.

Due to the trend of convergence in the telecommunications and broadcasting market, the Controlling Company needed to obtain control over a broadcasting company to enhance the synergy effects of the resources within the consolidated subsidiaries.

After the acquisition date, the revenue and net income for consolidation of KT Skylife Co., Ltd. before the elimination of intercompany transactions with its subsidiaries are ￦480,468 and ￦26,649 million, respectively. The difference between its revenue and net income from the acquisition date and the revenue and net income if KT Skylife Co., Ltd. had been consolidated from January 1, 2011, included in consolidation is insignificant.

The fair value of trade accounts receivable and other receivables acquired from KT Skylife Co., Ltd. is ￦140,180 million, while the full contract value is ￦168,693 million. The uncollectible amounts from these receivables are expected to be ￦28,513 million.
