|(2) | Basic earnings per share under Korean GAAP and U.S. GAAP is calculated by dividing net earnings by the weighted average number of shares outstanding during the period. The
weighted average number of shares of common stock outstanding during the period was 209,895 thousand for 2006, 206,599 thousand for 2007, 202,891 thousand for 2008, 219,513 thousand for 2009 and 243,207 thousand for 2010.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(3) | Diluted earnings per share are calculated based on the effect of dilutive securities that were outstanding during the period. The denominator of the diluted earnings per share
computation is adjusted to include the number of additional common shares that would have been outstanding if the dilutive securities had been converted into common stock. In addition, the numerator is adjusted to include the after-tax amount of
interest recognized associated with convertible notes. The weighted average number of common and common equivalent shares outstanding was 210,150 thousand for 2006, 206,599 thousand for 2007, 202,891 thousand for 2008,
224,168 thousand for 2009 and 243,225 thousand for 2010.

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 enables 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 enables 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.

Mobile Service.We provide mobile services based on Code Division Multiple Access (or CDMA) technology and Wideband Code Division Multiple Access (or W-CDMA) technology. Competitors in the mobile
telecommunications service industry are SK Telecom and LG U+. We had a market share of 31.6% as of December 31, 2010, making us the second largest mobile telecommunications service provider. SK Telecom had a market share of 50.6% as of
December 31, 2010.

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.

In recent years, SK Telecom and we also launched third-generation mobile telecommunications services, which we believe have further intensified
competition between the two companies and resulted in an increase in marketing expenses. We expanded our coverage area of High Speed Downlink Packet Access (or HSDPA)-based IMT-2000 services nationwide in March 2007. IMT-2000 is a third-generation,
high-capacity wireless communications technology, which allows operators to provide to their customers significantly more bandwidth capacity. Although we expect that SK Telecom will face similar challenges to those that we expect to face in
implementing this third-generation technology, we cannot assure you that we will continue to be able to successfully compete in third-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



5

##### Table of Contents

international long-distance telephone services. Starting in 1998, specific service providers, such as Internet phone service providers, voice resellers and call-back service providers, also began
offering 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, 2010, we had a market share in local telephone service of 86.3% and a market share in domestic long distance
service of 82.2%. 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 43.1% as of December 31, 2010. 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.

We may fail to realize the anticipated benefits of the merger of KTF into KT Corporation.

On June 1, 2009, KTF merged into KT Corporation, with KT Corporation surviving the merger. The success of the merger of KTF with KT Corporation will depend, in part, on our ability to realize the anticipated
synergies, growth opportunities and, to a lesser extent, cost savings from combining these two companies. The realization of these anticipated benefits may be impeded, delayed or reduced as a result of numerous factors, some of which are outside our
control. These factors include:



| |  |  | difficulties in integrating the operations of KTF with those of KT Corporation, including information systems, personnel, policies and procedures, and in
reorganizing or reducing overlapping personnel, operations, marketing networks and administrative functions;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | unforeseen contingent risks or latent liabilities relating to the merger that may become apparent in the future;
| | - |  | ----------------------------------------------------------------------------------------------------------------



| |  |  | difficulties in managing a larger business; and
| | - |  | -----------------------------------------------



| |  |  | loss of key management personnel or customers.
| | - |  | ----------------------------------------------

Accordingly, we cannot assure you that we will realize the anticipated benefits of the merger or that the merger will not adversely affect our combined business,
financial condition and results of operations.

The integration of the operations of KTF into KT Corporation may require significant
amounts of time, financial resources and management attention. KT Corporations management intends to implement a business plan to effectively combine the operations of KTF with the operations of



6

##### Table of Contents

KT Corporation. If this business plan is not effective in integrating these operations, however, we may not realize the anticipated benefits of the merger. The integration process could also
result in the disruption of our ongoing business and information technology systems, or inconsistencies in standards, controls, procedures and policies and a reduction in employee morale, each of which may adversely affect our ability to maintain
relationships with customers and to retain key personnel.

In addition, as conditions to the approval of the merger of KTF into KT
Corporation, the Korea Communications Commission is requiring us to (i) allow competing service providers to have greater access to our cable tunnels and telephone poles, (ii) improve Public Switched Telephone Network (or PSTN) number
portability and voice over Internet protocol (or VoIP) number portability, and (iii) allow competing service providers to access our wireless Internet network. Such conditions may intensify competition in the telecommunications industry, which
could have a material adverse effect on the number of our subscribers and 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. Our current right to use 40 MHz of bandwidth in the 1.8 GHz spectrum is scheduled to expire at the end of June 2011. We have applied to the Korea Communications Commission to allocate back to us 20 MHz of bandwidth in the 1.8 GHz spectrum,
for which we expect to pay a usage fee if reallocated to us. In addition, the Korea Communications Commission allocated 20 MHz of bandwidth in the 900 MHz spectrum to us, which will become effective on July 1, 2011. We expect 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 as determined by the Korea Communications Commission at the
time of allocation. In June 2011, the Korea Communications Commission announced its plan to auction in August 2011 the right to use 20 MHz of bandwidth in the 1.8 GHz spectrum that we are scheduled to relinquish at the end of June 2011, 10 MHz of
additional bandwidth in the 800 MHz spectrum and 20 MHz of additional bandwidth in the 2.1 GHz spectrum. According to the plan, a maximum of 20 MHz of bandwidth may be sold to a single service provider, and SK Telecom and we are prohibited from
bidding for the 20 MHz bandwidth in the 2.1 GHz spectrum. If we are allocated the bandwidths in the 800 MHz or the 1.8 GHz spectrums, we expect to pay usage fees for such bandwidths. 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.

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

We have been providing our 2G PCS services based on CDMA wireless network standards through our 40 MHz bandwidth in the 1.8 GHz spectrum, which allocation is expected to terminate at the end of June 2011. As part
of our decision to apply for reallocation, we have applied to the Korea Communications Commission to terminate our existing 2G PCS services, which we expect to be able



7



---

##### Table of Contents

to terminate in the second half of 2011. Accordingly, our existing 2G PCS subscribers must either convert to our W-CDMA services or switch to other telecommunications companies. As of
December 31, 2010, there were 1,393 thousand subscribers of our 2G PCS services. We are offering benefits such as substantial discounts on W-CDMA-compatible handsets and monthly subscription fees starting in March 2011 to encourage our
existing subscribers to switch to our W-CDMA services. However, there can be no assurance that we will not incur reputational damage from terminating our 2G PCS services, such termination will not lead to a material decrease in the number of our
mobile subscribers, or complaints and other potential actions of our 2G PCS subscribers will not adversely affect our business, financial condition and results of operations.

Introduction of new 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
(Won)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 82 cities nationwide and major highways as of March 2011, which we believe will allow 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 377 thousand subscribers as of December 31, 2010. In addition, 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. 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.

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 Korea Communications Commission, has authority to regulate the telecommunications industry. The Korea
Communications Commissions policy is to



8

##### Table of Contents

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 Korea Communications Commission, it must obtain prior approval from the Korea
Communications Commission for the rates and the general terms for that service. Each year the Korea Communications Commission 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 has so designated us for local telephone service and SK Telecom for mobile service, and the Korea Communications Commission, in consultation with the Ministry of Strategy and Finance,
currently approves rates charged by us and SK Telecom for such services. In June 2011, SK Telecom announced tariff reduction measures, including a reduction of the monthly fee by (Won)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. The Korea
Communications Commission 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 Korea Communications Commission.

The Government also sets the policies regarding the use of radio frequencies and allocates the spectrum of radio frequencies used for wireless telecommunications. On April 29, 2010, the Korea Communications
Commission announced its decision to allocate 20 MHz of bandwidth in the 900 MHz spectrum to us, 20 MHz of bandwidth in the 800 MHz spectrum to LG U+ (consisting of 15 MHz of bandwidth that is scheduled to be relinquished by SK Telecom by the end of
June 2011 following expiration of its license period and 5 MHz of currently unused bandwidth) and 20 MHz of bandwidth in the 2.1 GHz spectrum to SK Telecom, which SK Telecom began using in June 2010. New allocations of bandwidth to us and LG U+ will
become effective on July 1, 2011. We expect 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 as determined by the Korea Communications Commission at the time of allocation. In June 2011, the Korea Communications Commission announced its plan to auction in August 2011 the right to use 20 MHz of bandwidth in the 1.8 GHz spectrum that we
are scheduled to relinquish at the end of June 2011, 10 MHz of additional bandwidth in the 800 MHz spectrum and 20 MHz of additional bandwidth in the 2.1 GHz spectrum. According to the plan, a maximum of 20 MHz of bandwidth may be sold to a single
service provider, and SK Telecom and we are prohibited from bidding for the 20 MHz bandwidth in the 2.1 GHz spectrum. If we are allocated the bandwidths in the 800 MHz or the 1.8 GHz spectrums, we expect to pay usage fees for such bandwidths. 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 on November 17, 2008. IP-TV is a service which combines video-on-demand services with real-time
high definition broadcasting via broadband networks. The Korea Communications Commission has 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 Korea Communications Commission, and anyone intending to engage in the broadcasting of certain contents must obtain additional approval of the Korea Communications Commission. In
addition, KT Skylife Co. (formerly Korea Digital Satellite

Broadcasting Co., Ltd.), which became our consolidated subsidiary starting in 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 Korea Communications Commission 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 cross-guarantee of debt and cross-shareholdings among member companies of the same group. Any future determination 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 administrations and certain payments related to our derivative instruments entered into for foreign exchange risk hedging purposes. Of the
(Won)7,248 billion total principal amount of long-term debt (excluding current portion) outstanding as of December 31, 2010, (Won)2,188 billion was denominated in foreign currencies with an average weighted interest rate of 4.70%. The interest rates of such long-term debt
denominated in foreign currencies ranged from 0.77% (for US$100 million notes with a floating interest rate of three month London Interbank Offered Rate plus 0.47%) to 16.50% (for Uzbekistani Som 2,259,000 (approximately US$1.4 million) fixed rate
notes issued by East Telecom, our subsidiary located in Uzbekistan). 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 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 economy is subject to many factors beyond our
control.

The Korean economy is closely tied to, and is affected by developments in, the global economy. Recent difficulties affecting
the U.S. and global financial sectors, adverse conditions and volatility in the worldwide credit and financial markets, fluctuations in oil and commodity prices and the general weakness of the U.S. and global economy have increased the
uncertainty of global economic prospects in general and have adversely affected, and may continue to adversely affect, the Korean economy. Due to recent liquidity and credit concerns and volatility in the global financial markets, the value of the
Won relative to the Dollar has also fluctuated significantly in recent years. Furthermore, as a result of adverse global and Korean economic conditions, there has been continuing volatility in the stock prices of Korean companies. While the rate of
deterioration of the global economy slowed in the second half of 2009, with some signs of stabilization and improvement in 2010, the overall prospects for the Korean and global economy in 2011 and beyond remain uncertain. 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 housing and financial sectors in the United States and elsewhere and increased sovereign default risks in select countries and the resulting
adverse effects on the global financial markets;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | declines in consumer confidence and a slowdown in consumer spending;

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 current and future events. In recent years, there have been heightened security concerns stemming from North Koreas nuclear weapons and long-range missile programs and increased uncertainty
regarding North Koreas actions and possible responses from the international community. In January 2003, North Korea renounced its obligations under the Nuclear Non-Proliferation Treaty. Since the renouncement, Korea, the United States, North
Korea, China, Japan and Russia have held numerous rounds of six party multi-lateral talks in an effort to resolve issues relating to North Koreas nuclear weapons program.

In addition to conducting test flights of long-range missiles, North Korea announced in October 2006 that it had successfully conducted a nuclear
test, which increased tensions in the region and elicited strong objections worldwide. In May 2009, North Korea announced that it had successfully conducted a second nuclear test and test-fired three short-range surface-to-air missiles. In response,
the United Nations Security Council unanimously passed a resolution in June 2009 that condemned North Korea for the nuclear test and decided to expand and tighten sanctions against North Korea. In March 2010, a Korean warship was destroyed by an
underwater explosion, killing many of the crewmen on board. The government formally accused North Korea of causing the sinking in May 2010, and North Korea has denied responsibility for the sinking and has threatened retaliation for any attempt to
punish it for the act. On November 23, 2010, North Korean forces fired more than one hundred artillery shells targeting Yeonpyeong Island located near the maritime border between Korea and North Korea on the west coast of the Korean peninsula,
killing two Korean soldiers and two civilians as well as causing substantial property damage. Korea responded by firing approximately 80 artillery shells and putting the military on its highest alert level. The Government condemned North Korea for
the act and vowed stern retaliation should there be further provocation.

In addition, there recently has been increased uncertainty
with respect to the future of North Koreas political leadership and concern regarding its implications for political stability in the region. On September 28, 2010, Kim Jong-il, the North Korean ruler who reportedly suffered a stroke in
August 2008, named Kim Jong-un, his third son who is reported to be in his twenties, as the vice chairperson of the Central Military Commission and the general of the North Korean army. Although Kim Jong-il has designated his son to be his
successor, the implementation of the succession plan remains uncertain. North Koreas economy also faces severe challenges. 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. Such developments may further aggravate social and political tensions within North Korea.

Reunification of the two Koreas could occur in the future. Reunification may entail a significant economic commitment by Korea. In President Lee Myung Baks national address on August 15, 2010, he
suggested the possible adoption of a reunification tax in order to prepare for long-term economic burden associated with reunification. Such discussions on reunification are very preliminary, and it has not been decided whether or when such tax
would be implemented. If a reunification tax is implemented, it may lead to a decrease in domestic consumption, which in turn may have a material adverse effect on the Korean economy. In addition, there can be no assurance that the level of tension
on the Korean peninsula will not escalate in the future. Any further increase in tension, 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, financial condition and results of operations.

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 Korea Communications Commission 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 Korea Communications Commission 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 dissenters 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 dissenters 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.

##### Table of Contents

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 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.

Korean GAAP differs in significant respects from accounting standards applicable in certain other countries, including U.S. GAAP and the
International Financial Reporting Standards.

Our financial statements included in this annual report are prepared in accordance
with Korean GAAP and reconciled to U.S. GAAP. Korean GAAP differs in significant respects from accounting standards applicable in certain other countries, including U.S. GAAP. See Item 5. Operating and Financial Review and
ProspectsItem 5.B. Liquidity and Capital ResourcesU.S. GAAP Reconciliation and Recent Accounting Pronouncements in U.S. GAAP and Note 38 to Consolidated Financial Statements.

In March 2007, the Financial Services Commission and the Korea Accounting Institute announced a road map for the adoption of the Korean equivalent
of International Financial Reporting Standards (Korean IFRS), pursuant to which all listed companies in Korea, including us, will be required to prepare their annual financial statements beginning in 2011 that differ in certain respects
from International Financial Reporting Standards (IFRS) applied in other countries.

In preparation of such adoption, we
began preparing our internal financial statements under both Korean GAAP and Korean IFRS starting in January 2010. Beginning in 2011, we have discontinued reporting under Korean GAAP with reconciliation to U.S. GAAP and instead have commenced
reporting under Korean IFRS and we also plan to release annual financial statements prepared pursuant to IFRS as issued by the International Accounting Standards Board, or IASB. Although our accounting department is currently analyzing the effects
of adopting IFRS on our annual financial statements, it is not possible to estimate with any degree of certainty the exact impact on our annual financial statements from such adoption because the IFRS accounting policies to be adopted by us for such
financial statements have not been finalized. Accordingly, there can be no assurance that the adoption of IFRS will not adversely affect our reporting results of operations or financial condition.

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 used to be appointed by the Government under the Korea Telecom Act.

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
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.

| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

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 31.6% with approximately 16.0 million subscribers as of December 31, 2010;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | in the fixed-line telephone services market in Korea, we continue to be the dominant provider with approximately 25.5 million installed lines, of which
16.6 million lines were in service as of December 31, 2010. As of such date, our market share of the local market was 86.3% and our market share of the domestic long-distance market was 82.2%;

For the year ended December 31, 2010, under Korean GAAP, our operating revenues were
(Won)21,331 billion, our net income was
(Won)1,193 billion and our basic net income per share was (Won)4,803. As of December 31, 2010, our total shareholders equity was (Won)11,496 billion.

Business Strategy

We believe
the telecommunications market in Korea will continue to expand due to Koreas growing economy, consumers willingness to adopt new technologies, relatively high income and a relatively large middle class. 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. We also restructured our organization into three sub-groups, the Home Customer Group, the Personal Customer Group and the Enterprise Customer Group, so
that we may more effectively address differing needs of our customer segments. Consistent with our strategic objectives, we aim to pursue growth through the following four core areas:



| |  |  | Home Customer Group. We aim to offer a one-stop-shop that satisfies various information technology and telecommunications needs of a household. 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.

| |  |  | Personal Customer Group. Our Personal Customer Group focuses on expanding our wireless data communication business to meet the rising demand for
broadband Internet access using advanced wireless data communications devices such as smart phones. We are working closely with handset manufacturers to expand our offerings of smart phones 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 on November 28, 2009 and have
expanded our offerings of smart phones 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 portable devices, as well as
our extensive wireless LAN networks installed nationwide, enable our subscribers to maximize effective usage of their smart phones. 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 smart phone 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 smart phone 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.

solution services including designing data communications and information technology infrastructure to overseeing their day-to-day operations with the objective of achieving operational efficiencies and cost savings. 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 smart phones 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 50.8 million and the number of broadband Internet access subscribers in Korea was 17.2 million as of December 31, 2010. As of December 31, 2010, 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 103.9%, 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 100.4%.

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 Ministry of Information and Communication 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, SK Telecom and LG U+ have invested in networks compatible with
Evolution-Data Optimized (or EV-DO) handsets that allow subscribers to enjoy 2.5 generation high speed wireless data services. KT Corporation and SK Telecom also offer third-generation, high-capacity HSDPA-based IMT-2000 wireless Internet and video
multimedia communications services that use significantly greater bandwidth capacity.

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 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 smart phones 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 CDMA technology and W-CDMA
technology. Prior to the merger of KTF into KT Corporation, we provided such services through KTF, which was formerly a consolidated subsidiary. 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. KTF obtained one of the three licenses to
provide nationwide PCS service in June 1996 and began offering PCS service in October 1997. PCS service is a digital wireless telephone and data transmission system based on CDMA wireless network standards that uses portable handsets with long
battery life to communicate via low-power antennae. KTF also began offering 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 that allow an operator to provide to its subscribers significantly more bandwidth capacity.

We have been providing our 2G PCS
services based on CDMA wireless network standards through our 40 MHz bandwidth in the 1.8 GHz spectrum, which allocation is scheduled to terminate at the end of June 2011. As part of our decision to apply for reallocation, we have applied to the

Communications Commission to terminate our existing 2G PCS services, which we expect to be able to terminate in the second half of 2011. Accordingly, our existing 2G PCS subscribers must either
convert to our W-CDMA services or switch to other telecommunications companies. As of December 31, 2010, there were 1,393 thousand subscribers of our 2G PCS services. We are offering benefits such as substantial discounts on
W-CDMA-compatible handsets and monthly subscription fees to encourage our existing subscribers to switch to our W-CDMA services.

Revenues related to mobile service accounted for 33.2% of our operating revenues in 2010.In addition, our goods sold, which are primarily
from mobile handset sales, accounted for 20.6% of our operating revenues in 2010. 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:

|(1) | Prior to the merger of KTF into KT Corporation on June 1, 2009, we maintained an air-time reselling arrangement with KTF where we billed directly to our resale subscribers
for their usage of KTFs mobile networks and collected all fees and charges relating to such usage. Such amounts related to resale subscribers are not included in our calculation of outgoing minutes and average monthly outgoing minutes and
revenue per subscriber in 2008. In 2009 and 2010, we have included such amounts related to resale subscribers in these calculations.

|(2) | 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.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(3) | 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, 2010, we had approximately
16.0 million subscribers, which was second largest among the three mobile service providers. As of December 31, 2010, we had a market share of 31.6% of the mobile service market.

We market our mobile services primarily through independent exclusive dealers located throughout Korea. As of December 31, 2010, there were
approximately 2,200 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.

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 20.1% of our operating revenues in 2010. 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:

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. In recent years, we have also increased the proportion of our lines that 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. We completed connection of all installed lines to digital exchanges in June 2003.

China (18.5%), United States (17.0%) and Japan (16.8%) accounted for the greatest percentage of our
international long-distance call traffic measured in minutes in 2010. In recent years, the volume of our incoming calls 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). We expect that interconnection revenues and payments will remain important for our results of
operations. In recent years, revenues from a landline user for a call initiated by a landline user to a mobile service subscriber (land-to-mobile interconnection) have become a significant portion of our results of operations, accounting for 4.5% of
our operating revenues in 2010.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, 2010, we had approximately 2.7 million subscribers.

Internet Services

Broadband Internet Access Service. Leveraging on our nationwide network of 448,328 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 9.1% of our operating revenues in 2010.Our principal Internet access services include:



| |  |  | ADSL, VDSL, Ethernet and FTTH services under the olleh Internet brand name;

| |  |  | 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 3 Mbps per user.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We had 7.4 million fixed-line olleh Internet subscribers and approximately
266 thousand ollehWiFi service subscribers as of December 31, 2010.We commercially launched our WiBro service in June 2006, and we had approximately 377 thousand subscribers as of December 31, 2010. 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 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 2.9% of our operating revenues in 2010.

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 or Internet service providers 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

services under the brand name olleh TV. Our IP-TV service offers access to an array of digital media contents, including movies, sports, news, educational programs and TV replay, for a fixed monthly fee. 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 on November 17, 2008. We had 2.4 million olleh TV subscribers as of March 31, 2011.

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, 2008, 2009 and 2010, we leased 374,570 lines, 366,191 lines and 303,009 lines to domestic and
international businesses. The data communication service accounted for 6.1% of our operating revenues in 2010.

We provide dedicated and
secure broadband Internet connection service to institutional customers under the Kornet brand name. We provide high-speed connection up to 4.2 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.

We currently operate three satellites, Koreasat 3, Koreasat 5 and Koreasat 6. We launched Koreasat 3 in September 1999. The design life of Koreasat
3 is twelve years, and it will be used to back up the broadcasting services of Koreasat 6 until the end of its fuel life.

We launched
Koreasat 5 in August 2006, which replaced Koreasat 2. 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 (also known as olleh 1) in December 2010 to replace Koreasat 3. The design life of Koreasat 6 is fifteen years. Koreasat 6 began its commercial operation in February 2011 and carries
transponders that are 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 commercial satellite services to both domestic and international customers.

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.
| | - |  | ---------------------------------------------------------

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. For instance, during regular service hours, a call pulse is
triggered at the beginning of each local telephone call and every three minutes thereafter.

##### Table of Contents

The rates we charge for local calls are currently subject to approval by the Korea Communications
Commission after consultation with the Ministry of Strategy and Finance. The rates are identical for residential and commercial customers. The following table summarizes our local usage rates as of each date on which rates were revised:



|                                    |  |             |      |  |              |       |    |                |  |       |             |  |  |       |    |

|(1) | Since January 1, 1990, usage charges for local service in those metropolitan areas subject to measured service have been based on the number of pulses, which are a function
of the duration and number of calls, and per pulse rates. Before January 1, 1993, in areas not subject to measured service, a pulse was triggered once for each local telephone call, regardless of the length of the call. Commencing
January 1, 1993, measured service applies to all lines in service. 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.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We also charge a monthly basic charge ranging from (Won)3,000 to (Won)5,200, depending on
location, and a non-refundable service initiation fee of (Won)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, 2010, we
had (Won)616 billion of refundable service initiation deposits outstanding and 2,738 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 Korea Communications Commission.

The following table summarizes our domestic long-distance rates as of each date on which rates were revised. These charges do not reflect discounts applicable to calls made during off-peak hours or holidays.

|(1) | Domestic long-distance calls of up to 30 kilometers are billed on the same basis as local calls. Before April 15, 2001, for domestic long-distance calls in excess of 30
kilometers, a pulse was triggered at the beginning of each call and every 47 seconds for calls up to 100 kilometers or every 33 seconds for calls in excess of 100 kilometers. Commencing April 15, 2001, a pulse was triggered at the
beginning of each call and every 30 seconds thereafter. Commencing November 1, 2001, a pulse is triggered at the beginning of each call and every 10 seconds thereafter.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(2) | Rates for domestic long-distance calls in excess of 30 kilometers are currently discounted (by an adjustment in the period between pulses) by 10% on holidays and from 6:00 a.m.
to 8:00 a.m. on weekdays, and by 30% from midnight to 6:00 a.m. every day.

##### Table of Contents

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:



| |  |  | starting in June 2008, a subscriber who elects to pay a monthly flat rate of (Won)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;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | starting in October 2009, 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 (Won)39 per three minutes; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | starting in October 2009, 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 (Won)150,000 with a flat rate payment of (Won)50,000 or such calls up to (Won)50,000
with a flat rate payment of (Won)10,000. Standard rates apply to calls that exceed the capped amounts.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

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 and administrations 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 Korea Communications Commission.

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 or administration at the applicable settlement rate specified under the
agreement with the foreign entity. We have entered into numerous bilateral agreements with foreign carriers and administrations. We negotiate the settlement rates under these agreements with each foreign carrier, subject to Korea Communications
Commission 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 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 Korea Communications
Commission periodically issues orders setting the interconnection charge calculation method applicable to interconnections with mobile service providers. The Korea Communications Commission 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.

We recognize as land-to-mobile interconnection revenue the entire amount of the usage charge collected from the landline user and recognize as expense the amount of interconnection charge paid to the mobile service
provider.

Land-to-land and Mobile-to-land Interconnection. For a call initiated by a landline subscriber of our competitor to
our fixed-line user, the landline service provider collects from its subscriber its normal rate and remits to us a land-to-land interconnection charge. In addition, for a call initiated by a mobile service subscriber to our landline user, the mobile
service provider collects from its subscriber its normal rate and remits to us a mobile-to-land interconnection charge.

The following
table shows such interconnection charge per minute collected for a call depending on the type of call, as determined by the Korea Communications Commission.

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 enables 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 enables 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.

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 Korea Communications Commission 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 and broadband Internet access service, which require advance approval from the
Korea Communications Commission. 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 respective markets 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.

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



|                  |  |                  |      |  |            |  |      |       |  |  |      |

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 KT Corporation in terms of our revenues from fixed-line telephone services. We expect this trend to continue.

The following table shows the market share in the local telephone service market as of the dates indicated:

Although
the local usage charge of our competitors and us is the same at (Won)39 per pulse (generally three minutes) and the basic monthly charge of our
competitors and us is the same at (Won)5,200 depending on location, our competitors non-refundable telephone service initiation charges
are lower than ours. Our customers pay a non-refundable telephone service initiation charge of (Won)60,000 while customers of our competitors
pay a non-refundable telephone service initiation charge of (Won)30,000

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:

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 of 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.

Our competitors generally
charge less than us for international long-distance calls. The following table is a comparison of our standard long-distance usage charges per one minute with the standard rates of our competitors as of December 31, 2010:

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:



|                  |  |                  |      |  |             |  |      |       |  |  |        |  |  |  |      |

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 Korea Communications Commission. 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.

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

Under the
Telecommunications Basic Law and the Telecommunications Business Law, telecommunications service providers are currently classified into three categories:



| |  |  | network service providers, such as us, which typically provide telecommunications services with their own telecommunications networks and related facilities.
Their services may include local, domestic long-distance and international long-distance telephone services, mobile communications service, paging service and trunked radio system service;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | value-added service providers, which provide telecommunications services other than those services specified for network service providers, such as data
communications using telecommunications facilities leased from network service providers; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | specific service providers are broadly defined by law as telecommunications service providers that provide network services using the telecommunications network
facilities or services of network service providers.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Under the Telecommunications Basic Law and the
Telecommunications Business Law, the Korea Communications Commission has comprehensive regulatory authority over the telecommunications industry and all network service providers. 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. The Korea Communications Commission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. A network service provider must be licensed by the Korea Communications Commission. Our license as a network service provider permits us to engage in a
wide range of telecommunications services.



37



---

##### Table of Contents

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

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 Korea Communications Commission 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 Korea Communications Commission, it must obtain prior approval from the Korea Communications Commission for the rates and the general terms for that service. Each
year the Korea Communications Commission designates the service providers and the types of services for which the rates and the general terms must be approved by the Korea Communications Commission. In 2010, the Korea Communications Commission
designated us for local telephone service and SK Telecom for cellular service. The Korea Communications Commission, 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 Korea Communications Commission 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 Korea Communications Commission. The Korea Communications Commission can revoke our
licenses or order the suspension of any of our businesses if we do not comply with the regulations of the Korea Communications Commission under the Telecommunications Business Law.

##### Table of Contents

The responsibilities of the Korea Communications Commission also include:



| |  |  | formulating the basic plan for the telecommunications industry; and
| | - |  | -------------------------------------------------------------------



| |  |  | preparing periodic reports to the National Assembly of Korea regarding developments in the telecommunications industry.
| | - |  | -----------------------------------------------------------------------------------------------------------------------

In May 2010, the Korea Communications Commission issued a guideline that limits the marketing expenditure amounts of telecommunication service
providers in Korea to 22% of their revenues, with the restrictions applicable to fixed-line and mobile segments to be calculated separately. However, up to (Won)100 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. To encourage compliance with the non-binding guideline, the Korea Communications Commission plans to release the marketing expenditure amounts of each service
provider on a quarterly basis. The Korea Communications Commission may periodically adjust the guideline to accommodate changes in market conditions.

The responsibilities of the Ministry of Knowledge Economy include:



| |  |  | drafting and implementing plans for developing telecommunications technology;
| | - |  | -----------------------------------------------------------------------------



| |  |  | 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, since January 2000, 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 Korea Communications Commission 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 Korea
Communications Commission.

Due to the amendment of the Telecommunications Business Law, effective April 9, 2001, 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 Korea Communications Commission and be settled, by fair
and proper methods.

In addition, starting April 2002, 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



39

##### Table of Contents

lines that represent our excess capacity to other companies upon their request at rates that are determined by the Korea Communications Commission 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 services.

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, 2010, 48.52% 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 Korea Communications Commission 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.

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 Korea Communications Commission 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 Korea
Communications Commission 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, 2010 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

##### Table of Contents

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.

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.

We have 40 MHz of bandwidth in the 1.8 GHz spectrum to provide PCS services based on CDMA wireless
network standards and another 40 MHz of bandwidth in the 2.0 GHz spectrum to provide IMT-2000 services based on W-CDMA wireless network standards. Our current right to use 40 MHz of bandwidth in the 1.8 GHz spectrum is scheduled to expire at the end
of June 2011. We have applied to the Korea Communications Commission to allocate back to us 20 MHz of bandwidth in the 1.8 GHz spectrum, for which we expect to pay a usage fee if reallocated to us. In addition, the Korea Communications Commission
allocated 20 MHz of bandwidth in the 900 MHz spectrum to us, which will become effective on July 1, 2011. We expect 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 as determined by the Korea Communications Commission at the time of allocation. In June 2011, the Korea Communications Commission announced its plan to auction in August
2011 the right to use 20 MHz of bandwidth in the 1.8 GHz spectrum that we are scheduled to relinquish at the end of June 2011, 10 MHz of additional bandwidth in the 800 MHz spectrum and 20 MHz of additional bandwidth in the 2.1 GHz spectrum.
According to the plan, a maximum of 20 MHz of bandwidth may be sold to a single service provider, and SK Telecom and we are prohibited from bidding for the 20 MHz bandwidth in the 2.1 GHz spectrum. If we are allocated the bandwidths in the 800 MHz
or the 1.8 GHz spectrums, we expect to pay usage fees for such bandwidths. 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 24.0 million lines connected to local exchanges and 16.0 million lines connected to toll exchanges as of
December 31, 2010.

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, 2010, 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 an
aggregate traffic of our broadband Internet access subscribers, Internet data centers and Internet exchange system at any given moment of up to 4.6 Tbps as of December 31, 2010. 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, 2010, our Internet protocol premium network had 2,224,986 lines installed to provide voice over Internet protocol services and a total capacity to handle up to 595 Gbps of IP-TV, voice and
WiBro service traffic.

Access Lines

As of December 31, 2010, we had 14.5 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, 2010, we had approximately 12.7 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 484,701 kilometers of fiber optic cables as of December 31, 2010 of which 86,815 kilometers of fiber optic cables are used to connect our backbone network
and 397,886 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 consists of 55 relay sites.

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 315 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 250
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.

Satellites

In order to provide
broadcasting, video distribution and broadband data services in select areas, we operate two satellites, Koreasat 3, 5 and 6, launched in 1999, 2006 and 2011, respectively. 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;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------

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 Korean GAAP.
Korean GAAP varies in certain significant respects from accounting principles generally accepted in the United States of America. We have summarized these differences and their effect on our total equity as of December 31, 2009 and 2010 and the
results of our operations for each of the years in the three-year period ended December 31, 2010, in Note 38 to the Consolidated Financial Statements.

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. We determined
our operating segments after the merger with KTF on June 1, 2009 as (i) the Personal Customer Group, which engages in mobile and wireless data communications services, (ii) the Home Customer Group and Enterprise Customer Group, which
engage in fixed-line telephone services, Internet services including broadband Internet access service and data communication service, and (iii) others, which include information technology and network services, real estate development and car
rental businesses.

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:



| |  |  | merger of KTF into KT Corporation on June 1, 2009;
| | - |  | --------------------------------------------------



| |  |  | employee reductions and changes in severance and retirement benefits;

| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | transition to International Financial Reporting Standards starting in 2011.
| | - |  | ---------------------------------------------------------------------------

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

Merger of KTF into KT Corporation

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. The merger was consummated pursuant to a comprehensive stock transfer under Article 360-15 of the Korean Commercial Code, whereby KTF
common stockholders received 0.7192335 share of KT Corporation common stock for every one share of KTF common stock they owned.

The
success of the merger of KTF with KT Corporation will depend, in part, on our ability to realize the anticipated synergies, growth opportunities and, to a lesser extent, cost savings from combining these two companies. The realization of these
anticipated benefits may be impeded, delayed or reduced as a result of numerous factors, some of which are outside our control. Some of our challenges include difficulties in integrating the operations of KTF with those of KT Corporation, including
information systems, personnel, policies and procedures, and in reorganizing or reducing overlapping personnel, operations, marketing networks and administrative functions.

Employee Reductions and Changes in Severance and Retirement Benefits

We sponsor a
voluntary early retirement plan where we provide additional financial incentives for our employees who have been employed by us for more than 20 years to retire early, as part of our efforts to improve operational efficiencies. In 2008, 1,141
employees retired under our voluntary early retirement plan. In 2009, in addition to our usual voluntary early retirement plan, we held a special voluntary early retirement program in December 2009 where 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. In aggregate, 6,515 employees retired in 2009 under the voluntary early retirement plan and the special voluntary early retirement program. In 2010, 123 employees retired under our voluntary early retirement plan.
We recorded severance indemnities relating to such voluntary early retirement plan and special voluntary early retirement program of (Won)97
billion in 2008, (Won)878 billion in 2009 and (Won)13 billion in 2010.

IMT-2000 Service License Payments

We acquired the right to purchase one of three licenses to provide IMT-2000 services on December 15, 2000, as a member of a consortium of
companies including KT Corporation and KTF. In March 2001, KT ICOM, a company created by the consortium, paid half of the (Won)1.3 trillion
license fee payable to the Korea Communications Commission. KTF, which subsequently merged with KT ICOM, paid (Won)110 billion in 2008, (Won)130 billion in 2009 and (Won)150
billion in 2010, and we are obligated to pay the remaining (Won)170 billion in 2011. This payable accrues interest at the applicable three-year
Government bond interest rate minus 0.75%. The accrued interest is paid on an annual basis to the Korea Communications Commission. We began offering our HSDPA-based IMT-2000 services nationwide in March 2007.

Changes in the Rate Structure for Our Services

Periodically, we change 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 began
offering 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. 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, in March 2005, we acquired a license to provide WiBro service for (Won)126 billion, and commercially launched the service in June 2006. We completed the upgrade of our 4G WiBro network and expanded our WiBro service
coverage to 82 cities nationwide and major highways as of March 2011, which we believe will allow 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
377 thousand subscribers as of December 31, 2010. In addition, 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. 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.

Transition to International Financial Reporting Standards Starting in 2011

In March 2007, the Financial Services Commission and the Korea Accounting Institute announced a road map for the adoption of Korean IFRS, pursuant
to which all listed companies in Korea, including us, will be required to prepare their annual financial statements beginning in 2011 that differ in certain respects from IFRS applied in other countries.

In preparation of such adoption, we began preparing our internal financial statements under both Korean GAAP and Korean IFRS starting in January
2010. Beginning in 2011, we have discontinued reporting under Korean GAAP with reconciliation to U.S. GAAP and instead have commenced reporting under Korean IFRS and we also plan to release annual financial statements prepared pursuant to IFRS as
issued by the IASB. Although our accounting department is currently analyzing the effects of adopting IFRS on our annual financial statements, it is not possible to estimate with any degree of certainty the exact impact on our annual financial
statements from such adoption because the IFRS accounting policies to be adopted by us for such financial statements have not been finalized. Accordingly, there can be no assurance that the adoption of IFRS will not adversely affect our reporting
results of operations or financial condition.

Critical Accounting Policies

The preparation of financial statements in conformity with Korean GAAP requires management to make 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 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;
| | - |  | ----------------------------------------------------



| |  |  | impairment of investment securities;
| | - |  | ------------------------------------



| |  |  | income taxes; and
| | - |  | -----------------



| |  |  | valuation of derivatives.
| | - |  | -------------------------

Allowances for Doubtful Accounts

Allowance for doubtful accounts is our best estimate of the amount of probable credit losses in our existing notes and accounts receivable. We determine the allowance for doubtful notes and



47

##### Table of Contents

accounts receivable based on an analysis of portfolio quality and historical write-off experience. 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 each of the years in the three-year period ended December 31, 2010 are summarized as follows:



|                             |  |                         |          |   |      |       |          |      |  |       |          |  
|---------------------------- |  | ----------------------- | -------- | - | ---- | ----- | -------- | ---- |  | ----- | -------- | -
|                             |  | Year Ended December 31, |         
|                             |  | 2008                    |          |   | 2009 |       |          | 2010 | 
|                             |  | (In millions of Won)    |         
|Balance at beginning of year |  | (Won)                   | 487,729  |   |      | (Won) | 488,739  |      |  | (Won) | 477,124  |  
|Provision                    |  |                         | 148,972  |   |      |       | 104,977  |      |  |       | 171,195  |  
|Write-offs                   |  |                         | (147,962 | ) |      |       | (116,592 | )    |  |       | (133,095 | )
|                             |  |                         |          |   |      |       |          |      |  |       |          |  
|Balance at end of year       |  | (Won)                   | 488,739  |   |      | (Won) | 477,124  |      |  | (Won) | 515,224  |  
|                             |  |                         |          |   |      |       |          |      |  |       |          |  

If economic or specific industry trends change, we would adjust our allowances for doubtful accounts by recording
additional expense or benefit. Our study shows that a 5.0% decrease or increase in the historical write-off experience would increase or decrease the provision for doubtful accounts by approximately
(Won)13 billion as of December 31, 2010.

Useful Lives of Property and Equipment

Property and equipment are depreciated based on
the useful lives disclosed in Note 3 to the Consolidated Financial Statements. Generally, the useful lives are estimated at the time the asset is acquired and are based on historical experience with similar assets as well as taking into account
anticipated technological or other changes. In certain cases and as permitted under Korean GAAP, those useful lives used for accounting purposes are different from the estimated economic lives of the related asset. In addition, the estimated lives
of certain other assets, including underground access to cable tunnels, and concrete and steel telephone poles are based on rates established by a ruling by the Korean National Tax Service (which is also applicable under Korean GAAP). 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 (Won)248 billion in 2010.

Impairment of Long-Lived Assets

Long-lived assets generally consist of property and equipment and intangible assets. 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 considered
when estimated undiscounted future net cash flow expected to result from the use of the asset and its eventual disposition are less than its carrying amount. 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 fair value of the assets.

Our intangible assets include the
IMT-2000 frequency usage right, which has a contractual life of 13 years and is amortized from the date commercial service is initiated through the end of its contractual life, which is November 2016. We started to amortize this frequency usage
right in December 2003, and we review the IMT-2000 frequency usage right for impairment on an annual basis. In connection with our review, we utilize the estimated long-term revenue and cash flow



48



---

##### Table of Contents

forecasts developed as part of our planning process. The results of our review using the testing method described above did not indicate any need to impair the IMT-2000 frequency usage right in
2010. The use of different assumptions within our cash flow model could result in different amounts for the IMT-2000 frequency usage right.

Impairment of Goodwill

Goodwill represents the excess of purchase price paid over the
fair value assigned to the 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 goodwill, 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.

We evaluate the carrying value of goodwill annually or more frequently if events or
changes in circumstances indicate that the carrying amount may exceed estimated fair value. Goodwill impairment testing is a two-step process. The first step involves determining the fair value of the reporting unit and comparing that to the book
value. If the fair value exceeds the book value, then no further testing is required. If the fair value is less than the book value, then a second step is performed. In the second step, the fair values of all of the assets and liabilities of the
reporting unit, including those that may not be currently recorded, are determined. The difference between the sum of all of those fair values and the overall reporting units fair value is a new implied goodwill amount that is compared to the
recorded goodwill. If implied goodwill is less than the recorded goodwill, then impairment to the recorded goodwill is recorded.

Impairment of Investment Securities

For investments in companies, whether or not publicly held, that are not controlled, but under our significant influence, we utilize the equity method of accounting. Under the equity method of accounting, our
initial investment is recorded at cost and is subsequently increased to reflect our share of the investee income and reduced to reflect our share of the investee losses or dividends received. Any excess in our acquisition cost over our share of the
investees identifiable net assets is generally recorded as investor-level goodwill or other intangibles and amortized by the straight-line method over the estimated useful life. The amortization of investor-level goodwill or other intangibles
is recorded against the equity income (losses) of affiliates.

Significant management judgment is involved in the evaluation of declines
in value of individual investments. The estimates and assumptions used by management to evaluate declines in value 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 and, for publicly-traded securities, the length of time and the extent to which fair value has been less than cost. 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



49



---

##### Table of Contents

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.

We believe that the accounting estimate related to establishing tax valuation allowances 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.

Valuation of Derivatives

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 the change in the fair value of derivative
instruments are recognized in current earnings. However, for derivative instruments that qualify for cash flow hedge accounts, the effective portion of the gain or loss on the derivative instruments are recorded as gain (loss) on valuation of
derivatives for cash flow hedge included in accumulated other comprehensive income (loss).

Significant management judgment is involved
in determining the fair value of derivative instruments. The estimates and assumptions used by our management to determine fair value can be impacted by many factors, such as the credit quality of each derivative counterparty, interest rate, market
volatility or the overall condition of the economy and its impact on the capital markets. Any changes in these assumptions could significantly affect the valuation and timing of recognition of valuation losses classified as other than temporary.

##### Table of Contents

Total operating revenues increased by 8.6%, or
(Won)1,687 billion, from (Won)19,644
billion in 2009 to (Won)21,331 billion in 2010 primarily due to increases in our mobile handset sales, other operating revenues and mobile
service revenues, the impact of which was partially offset by decreases in our fixed-line telephone service revenues.

Mobile
Services

Our mobile service revenues increased by 6.6%, or (Won)437 billion, from (Won)6,646 billion in 2009 to
(Won)7,083 billion in 2010 primarily due to a 6.8% increase in the number of mobile subscribers from 15.0 million as of December 31,
2009 to 16.0 million as of December 31, 2010.

Fixed-line Telephone Services

Our fixed-line telephone service revenues decreased by 9.1%, or (Won)427 billion, from (Won)4,697 billion in 2009 to
(Won)4,270 billion in 2010 primarily due to decreases in land-to-mobile interconnection revenues, local service revenues and domestic
long-distance revenues. Specifically:



| |  |  | Land-to-mobile interconnection revenues decreased by 17.3%, or (Won)198 billion, from (Won)1,147 billion in 2009 to
(Won)949 billion in 2010 primarily due to an increase in the volume of calls between mobile subscribers, which in turn led to a reduction in
the volume of calls between landline users to mobile subscribers.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Local service revenues decreased by 4.2%, or (Won)111
billion, from (Won)2,674 billion in 2009 to (Won)2,563 billion in 2010. The number of local call pulses decreased by 5.2% from 2009 to 2010 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.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Domestic long-distance revenues decreased by 19.8%, or
(Won)94 billion, from (Won)475
billion in 2009 to (Won)381 billion in 2010 primarily due to a decrease in the number of domestic long-distance call minutes by 23.2% from 2009
to 2010 primarily due to the substitution effect from increase in usage of mobile telephone services and Internet phone services. The effect of such decreases was partially offset by participation by some of our subscribers in optional flat rate
plans.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Internet Services

Our Internet service revenues increased by 4.8%, or (Won)118 billion, from (Won)2,449 billion in 2009 to (Won)2,567
billion in 2010 primarily due to an increase in the number of IP-TV subscribers from 1.2 million as of December 31, 2009 to 2.1 million as of December 31, 2010. The revenues from broadband Internet access service remained stable
at (Won)1,942 billion in 2009 and
(Won)1,941 billion in 2010.

Goods Sold

Revenues from
goods sold increased by 29.4%, or (Won)998 billion, from (Won)3,397 billion in 2009 to (Won)4,395 billion in 2010 primarily due to an increase in the number of
HSDPA-based IMT-2000 service compatible handsets and smart phones sold, including Apple iPhones that we launched in November 2009.

Data Communications

Data communications service revenues decreased by 0.4%, or (Won)5 billion, from (Won)1,314 billion in 2009 to (Won)1,309
billion in 2010 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.

Others

Other operating revenues increased by 49.6%, or (Won)566 billion, from (Won)1,141 billion in 2009 to (Won)1,707
billion in 2010 primarily due to an increase in sales of our real estate properties.

|(1) | Including transfer to other accounts.
|--- | -------------------------------------

Total
operating expenses increased by 2.6%, or (Won)483 billion, from (Won)18,673 billion in 2009 to (Won) 19,156 billion in 2010 primarily due to increases in cost of goods
sold, cost of services, commissions and promotion expenses, the impact of which was partially offset by decreases in provision for severance benefits related to special voluntary early retirement programs, employee welfare and sales commissions.
Specifically:



| |  |  | Cost of goods sold increased by 31.1%, or (Won)968
billion, from (Won)3,119 billion in 2009 to (Won) 4,087 billion in 2010 primarily due to an increase in the number of high-end HSDPA-compatible handsets and smart phones sold, including the Apple iPhone that we launched in November 2009, as well as
various other smart phones that we launched in 2010.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Cost of services, which primarily relate to purchases of content for IP-TV services, increased by 38.2%, or
(Won)222 billion, from (Won)582
billion in 2009 to (Won)804 billion in 2010 primarily due to an increase in sales of pay-per-view programming to IP-TV subscribers.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our commissions, which primarily relate to payments for third-party outsourcing services, including commissions to the call center staff, increased by 14.9%, or (Won)188 billion, from (Won) 1,262
billion in 2009 to (Won)1,450 billion in 2010 primarily due to outsourcing of our activation and installation activities to third-parties.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | Our promotion expenses, which consist primarily of handset subsidies, increased by 9.4%, or (Won)106 billion, from (Won)1,122 billion in 2009 to
(Won)1,228 billion in 2010 primarily due to an increase in the sales volume of HSDPA-compatible handsets and smart phones.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

These factors were partially offset by the following:



| |  |  | Our provision for severance benefits decreased by 78.5%, or
(Won)885 billion, from (Won)1,128
billion in 2009 to (Won)243 billion in 2010 primarily due to a decrease in provision for severance benefits relating to a special voluntary
early retirement program. In December 2009, we held a special voluntary early retirement program in which 5,992 employees participated and received additional financial incentives to retire early, whereas we did not have any such special voluntary
early retirement program in 2010.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Employee welfare, which primarily relates to expenditures for employees such as education and healthcare subsidies, decreased by 36.2%, or (Won)213 billion, from (Won)587 billion in
2009 to (Won)374 billion in 2010 primarily due to a change in our compensation policy which reduced certain seasonal bonuses classified as
employee welfare, and instead increased benefits classified as salaries.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Sales commissions, which primarily relate to procurement of mobile subscribers and mobile handset sales by our independent dealers, decreased by 10.1%, or (Won)184 billion, from (Won)1,805 billion
in 2009 to (Won)1,621 billion in 2010 primarily due to a decrease in the rate of sales commissions we paid to our independent dealers.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Operating Income

Due to the factors described above, our operating income increased by 124.1%, or (Won)1,204 billion, from (Won)971 billion in 2009 to (Won)2,175
billion in 2010. Our operating margin, which is operating income as a percentage of operating revenues, increased from 4.9% in 2009 to 10.2% in 2010.

##### Table of Contents

Our net non-operating expenses increased by 144.2%, or (Won)362 billion, from (Won)251 billion in
2009 to (Won)613 billion in 2010 primarily due to our recognition of net other non-operating revenues in 2009 compared to net other
non-operating losses in 2010, a decrease in net foreign currency translation gain, a decrease in interest income, an increase in net loss on disposal of property and equipment and an increase in donations, the impact of which was partially offset by
a decrease in net loss on valuation of derivatives. Specifically:



| |  |  | We recorded net other non-operating revenues of
(Won)230 billion in 2009 compared to net other non-operating losses of (Won)21 billion in 2010 primarily due to refunds of (Won)90 billion to our subscribers of fixed-line
telephone services with optional flat rate plans who requested termination of such plans in 2010.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our net foreign currency translation gain decreased by 84.8%, or (Won)189 billion, from (Won)223 billion in 2009 to
(Won)34 billion in 2010 as the Market Average Exchange Rate of the Won against the U.S. dollar appreciated from (Won)1,257.5 to US$1.00 as of December 31, 2008 to (Won) 1,167.6 to US$1.00 as of December 31, 2009 but the level of appreciation decreased during 2010 to
(Won)1,138.9 to US$1.00 as of December 31, 2010. The impact of such decrease in net foreign currency translation gain was largely offset
by a decrease in net loss on valuation of derivatives discussed below.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our interest income decreased by 27.5%, or (Won)54
billion, from (Won)197 billion in 2009 to
(Won)143 billion in 2010 primarily due to a decrease in our average balance of interest-earning assets from 2009 to 2010, including our
holdings of cash and cash equivalents, as well as a general decrease in interest rates in Korea during such periods.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our net loss on disposal of property and equipment increased by 38.7%, or (Won)46 billion, from (Won)119 billion in 2009 to
(Won)165 billion in 2010 primarily due to an increase in equipment disposal, in particular machinery.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our donations increased by 106.2%, or (Won)42 billion,
from (Won)39 billion in 2009 to
(Won)81 billion in 2010 primarily due to an increase in our donations to employee welfare funds.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

These factors were partially offset by our net loss on valuation of derivatives, which decreased by 95.5%, or (Won)166 billion, from (Won)174 billion in
2009 to (Won)8 billion in 2010 primarily due to a decrease in losses from our combined interest rate currency swap contracts as the exchange
rate of the Won against the U.S. dollar fluctuated as discussed above.

Income Tax Expense on Continuing Operations

Our income tax expense on continuing operations increased by 244.4%, or
(Won)264 billion, from (Won) 108
billion in 2009 to (Won)372 billion in 2010 primarily due to an increase in income before income tax expense as well as a decrease in tax
credit carryforwards and deductions. See Note 26 to the Consolidated Financial Statements. Our effective tax rate increased from 15.0% in 2009 to 23.8% in 2010, primarily due to a decrease in tax credit carryforwards and deductions in 2010. We had
net deferred income tax assets of (Won)545 billion as of December 31, 2010.

Net Income

Due to
the factors described above, our net income increased by 95.6%, or (Won)583 billion, from
(Won) 610 billion in 2009 to
(Won)1,193 billion in 2010. Our net income margin, which is net income as a percentage of operating revenues, increased from 3.1% in 2009 to
5.6% in 2010.

Total operating revenues increased by 0.3%, or (Won)57 billion, from (Won)19,587 billion in 2008 to
(Won)19,644 billion in 2009 primarily due to increases in our mobile handset sales, mobile service revenues and other operating revenues, the
impact of which was partially offset by decreases in our fixed-line telephone service revenues, Internet service revenues and data communication service revenues.

Mobile Services

Mobile service revenues increased by 3.5%, or (Won)222 billion, from (Won)6,424 billion
in 2008 to (Won)6,646 billion in 2009 primarily due to a 4.5% increase in the number of mobile subscribers from 14.4 million as of
December 31, 2008 to 15.0 million as of December 31, 2009.

Fixed-line Telephone Services

Our fixed-line telephone service revenues decreased by 9.7%, or (Won)503 billion, from (Won)5,200 billion in 2008 to
(Won)4,697 billion in 2009 primarily due to decreases in land-to-mobile interconnection revenues, domestic long-distance revenues and local
service revenues.Specifically:



| |  |  | Land-to-mobile interconnection revenues decreased by 17.5%, or (Won)244 billion, from (Won)1,391 billion in 2008 to
(Won)1,147 billion in 2009 primarily due to an increase in the volume of calls between mobile subscribers, which in turn reduced the volume of
calls between landline users to mobile subscribers.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Domestic long-distance revenues decreased by 19.1%, or
(Won)112 billion, from (Won)587
billion in 2008 to (Won)475 billion in 2009 primarily due to a decrease in the number of domestic long-distance call minutes in 2009 compared
to 2008 primarily due to the substitution effect from increase in usage of mobile telephone services and Internet phone services. The effect of such decreases was partially offset by participation by some of our subscribers in optional flat rate
plans.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Local service revenues decreased by 2.8%, or (Won)78
billion, from (Won)2,752 billion in 2008 to (Won)2,674 billion in 2009. The number of local call pulses in 2009 compared to 2008 decreased by 32.5% primarily due to the substitution effect from increase in usage of mobile telephone services and the
Internet phone services. However, the effect of such decreases was substantially offset by participation by some of our subscribers in optional flat rate plans, as well as an increase in revenues from value-added services.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Internet Services

Our Internet service revenues decreased by 1.3%, or (Won)32 billion, from (Won)2,481 billion in 2008 to (Won)2,449
billion in 2009 primarily due to a decrease in broadband Internet access service revenues, the impact of which was partially offset by an increase in other Internet-related service revenues. Specifically:



| |  |  | Broadband Internet access service revenues decreased by 4.9%, or (Won)99 billion, from (Won)2,041 billion in 2008 to
(Won)1,942 billion in 2009, primarily due to discounts offered to long-term subscribers and bundled products in 2009. The effect of such
decreases was offset in part by an increase in the number of fixed-line olleh Internet subscribers from 6.7 million subscribers as of December 31, 2008 to 7.0 million subscribers as of December 31, 2009.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Other Internet-related service revenues increased by 15.2%, or (Won)67 billion, from (Won)440 billion in 2008 to
(Won)507 billion in 2009 primarily due to increases in revenues from our IP-TV services.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Goods Sold

Revenues from
goods sold increased by 10.8%, or (Won)331 billion, from (Won)3,066 billion in 2008 to (Won)3,397 billion in 2009 primarily due to an increase in the number of
HSDPA-based IMT-2000 service compatible handsets and smart phones sold, including the Apple iPhone that we launched in November 2009.

Data Communications

Data
communications service revenues decreased by 1.6%, or (Won)22 billion, from (Won)1,336 billion in 2008 to (Won)1,314 billion in 2009 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.

Others

Other operating revenues increased by 5.6%, or (Won)61 billion, from (Won)1,080 billion in 2008 to (Won)1,141

Total
operating expenses increased by 2.9%, or (Won)529 billion, from (Won)18,144 billion in 2008 to (Won)18,673 billion in 2009 primarily due to increases in severance
indemnities related to special voluntary early retirement programs and cost of goods sold, the impact of which was partially offset by decreases in depreciation, sales commissions and commissions. Specifically:



| |  |  | Our severance indemnities increased significantly by 212.5%, or (Won)767 billion, from (Won)361 billion in 2008 to
(Won)1,128 billion in 2009 primarily due to an increase in severance indemnities relating to a special voluntary early retirement program. In
December 2009, we held a special voluntary early retirement program where 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.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Cost of goods sold increased by 31.9%, or (Won)754
billion, from (Won)2,365 billion in 2008 to (Won)3,119 billion in 2009 primarily due to an increase in the sales of Internet phone handsets as well as an increase in the number of high-end HSDPA-compatible handsets and smart phones sold, including the
Apple iPhone that we launched in November 2009.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

These factors were partially offset by the following:



| |  |  | Depreciation decreased by 10.6%, or (Won)340 billion,
from (Won)3,214 billion in 2008 to
(Won)2,874 billion in 2009 reflecting a general decrease in our capital expenditures through 2009.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Sales commissions, which primarily relate to procurement of mobile subscribers and mobile handset sales by our independent dealers, decreased by 15.3%, or (Won)325 billion, from (Won)2,130 billion
in 2008 to (Won)1,805 billion in 2009 primarily due to a decrease in the number of new mobile subscribers.

Our net non-operating
expenses decreased by 65.8%, or (Won)482 billion, from (Won)733 billion in 2008 to (Won)251 billion in 2009 primarily due to net foreign currency translation
loss in 2008 compared to net foreign currency translation gain in 2009, an increase in reversal of impairment loss on property and equipment and net loss on disposal of equity method investment securities in 2008 compared to net gain on disposal of
equity method investment securities in 2009, the impact of which was partially offset by net gain on valuation of derivatives in 2008 compared to net loss on valuation of derivatives in 2009. Specifically:



| |  |  | We recorded net foreign currency translation loss of
(Won)762 billion in 2008 compared to net foreign currency translation gain of (Won)223 billion in 2009 as the Market Average Exchange Rate of the Won against the U.S. dollar depreciated from (Won) 938.2 to US$1.00 as of December 31, 2007 to (Won)1,257.5 to US$1.00 as of December 31,
2008 but appreciated to (Won)1,167.6 to US$1.00 as of December 31, 2009. The impact of such foreign currency translation gain/loss was
largely offset by loss/gain from valuation of derivatives discussed below.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our reversal of impairment loss on property and equipment increased sixteen-fold, or (Won)97 billion, from (Won)6 billion in 2008 to
(Won)103 billion in 2009 primarily due to an increase in compensation that we received from third parties for relocation of our property and
equipment that resulted in impairment loss.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We did not record any net gain on disposal of equity method investment securities in 2008 compared to net gain on disposal of equity method investment securities
of (Won)62 billion in

| | 2009. We recorded such gain in 2009 primarily due to the sale of our interest in U-Mobile. We sold all of our interest in U-Mobile with a book value of (Won)65 billion for US$100 million to a third party in September 2009.
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

These factors were partially offset by the following:



| |  |  | We recorded net gain on valuation of derivatives of
(Won)640 billion in 2008 compared to net loss on valuation of derivatives of (Won)174 billion in 2009 primarily due to gains and losses from our combined interest rate currency swap contracts as the exchange rate of the Won against the U.S. dollar fluctuated as discussed above.

Income Taxes Expense on Continuing Operations

Our income tax expense on continuing operations decreased by 35.7%, or (Won)60 billion, from (Won)168 billion in 2008 to
(Won)108 billion in 2009 primarily due to decreases from changes in deferred income tax assets unrecognized related to equity method investment
securities as well as tax rate changes, the impact of which was partially offset by a decrease in tax credits. See Note 26 to the Consolidated Financial Statements. Our effective tax rate decreased from 23.7% in 2008 to 15.1% in 2009, primarily due
to higher tax credit carryforwards in 2009 compared to 2008. We had net deferred income tax assets of (Won)551 billion as of December 31,
2009.

Net Income

Due to the factors described above, our net income increased by 18.9%, or (Won)97 billion, from (Won)513 billion in 2008 to (Won)610
billion in 2009. Our net income margin, which is net income as a percentage of operating revenues, increased from 2.6% in 2008 to 3.1% in 2009.

billion in 2008 to (Won)10,109 billion in 2009, primarily due to a decrease in fixed-line telephone service revenues, the impact of which was
partially offset by an increase in revenues from Internet-related services.

We recorded operating income, prior to adjusting for
inter-segment transactions, of (Won)1,113 billion in 2008 compared to operating loss of
(Won)44 billion in 2009, as the 14.2% decrease in the segments operating revenues outpaced a 4.9% decrease in operating expenses,

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 (Won)3,362 billion in 2008, (Won)2,774
billion in 2009 and (Won)3,239 billion in 2010 for the acquisition of property and equipment, primarily construction-in-progress. In our
financing activities, we used cash of (Won)2,147 billion in 2008, (Won)1,446 billion in 2009 and (Won)1,895 billion in 2010 for repayment of current portion of bonds and
long-term borrowings.

In recent years, we have also required capital for acquisitions of treasury shares for retirement and payments of
retirement and severance benefits related to our early retirement programs. For the acquisition of treasury shares for retirement, we spent
(Won)74 billion in 2008, (Won)528
billion in 2009 and (Won)0.3 billion in 2010. Subsequent to such repurchases, we retired most of the treasury shares that we repurchased. We
also recorded payments of severance benefits of (Won)221 billion in 2008, (Won)1,345 billion in 2009 and (Won)1,249 billion in 2010. In 2009 and 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. On June 1, 2009, KTF merged into KT Corporation pursuant to a comprehensive stock transfer under Article 360-15 of the Korean Commercial Code, whereby KTF common stockholders received
0.7192335 share of KT Corporation common stock for every one share of KTF common stock they owned. We delivered 45,629,480 treasury shares and 700,108 shares of our newly issued common shares to KTF shareholders in connection with the merger.

Our cash dividends amounted to
(Won)409 billion in 2008, (Won)229
billion in 2009 and (Won)494 billion in 2010.

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 additional treasury shares and 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 18 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, 2010:

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 net income, expenses not involving cash payments such as depreciation and amortization, and proceeds from issuance of bonds and long-term borrowings. We expect that these sources will continue to be our
principal sources of cash in the future. Net income was (Won)513 billion in 2008,
(Won)610 billion in 2009 and
(Won)1,193 billion in 2010 due to the reasons discussed in Item 5.A. Operating Results. Depreciation and amortization was (Won)3,703 billion in 2008, (Won)3,361
billion in 2009 and (Won)3,285 billion in 2010 primarily reflecting our capital investment activities during the recent years. Aggregate cash
proceeds from issuance of bonds and long-term borrowings were (Won)3,780 billion in 2008,
(Won)1,499 billion in 2009 and
(Won)2,035 billion in 2010. We also met the capital required for the June 2009 merger with KTF through delivery of 45,629,480 treasury shares
and 700,108 shares of our newly issued common shares to KTF shareholders in consideration of the merger. As of December 31, 2010, we held 17,895,964 treasury shares.

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 updated our Medium Term Note program in June 2005 from US$1 billion
to US$2 billion, of which US$700 million remained unused as of December 31, 2010. 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 shareholders equity was (Won)11,088 billion as of December 31, 2008, (Won)10,667 billion as of December 31, 2009 and (Won)11,496 billion as of December 31, 2010.

Liquidity

We had a working capital
(current assets minus current liabilities) surplus of (Won)1,833 billion as of December 31, 2008, (Won)1,031 billion as of December 31, 2009 and (Won)643 billion as of December 31, 2010.The following table sets forth the summary of our significant current assets for the periods indicated.

as of December 31, 2010. Under Korean GAAP, bank deposits and all highly liquid temporary cash instruments within maturities of three months are considered as cash equivalents. Short-term
investment assets primarily consist of time and trust deposits with maturities between four to twelve months and short-term loans and current portion of securities such as beneficiary certificates and available-for-sale securities.

As of December 31, 2010, we entered into various commitments with financial institutions totaling (Won)2,722 billion and US$101 million. See Note 18 to the Consolidated Financial Statements. As of December 31, 2010, (Won)563 billion and US$19 million were outstanding 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 (Won)3,362 billion in
2008, (Won)2,774 billion in 2009 and
(Won)3,239 billion in 2010 for the acquisition of property and equipment, primarily construction-in-progress.

Our current capital expenditure plan, on a non-consolidated basis, calls for the expenditure of approximately (Won)3,200 billion in 2011, which may be adjusted depending on market conditions and our results of operations. The principal components of our
capital investment plans are:



| |  |  | approximately (Won)476 billion in general expansion and
modernization of our network infrastructure;
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | approximately (Won)1,026 billion in capital investments
for IMT-2000 (W-CDMA) service;
| | - |  | --------------------------------------------------------------------------------------



| |  |  | approximately (Won)100 billion in capital investments
for WiBro service;
| | - |  | ------------------------------------------------------------------------



| |  |  | approximately (Won)186 billion in capital investments
for IP-TV service; and
| | - |  | ----------------------------------------------------------------------------



| |  |  | approximately (Won)127 billion in capital investments
for development of services over Internet protocol.
| | - |  | ---------------------------------------------------------------------------------------------------------

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 4.7% in
2008, 2.8% in 2009 and 2.9% in 2010. 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.

Recent Accounting Pronouncements in Korean GAAP

We did not adopt any significant Korean accounting standards issued or revised in 2010.

U.S. GAAP Reconciliation

In 2008, we recorded net income of (Won)573 billion under U.S. GAAP compared to net income of (Won)513 billion under Korean GAAP, primarily because of difference in the treatment of reversal of goodwill amortization and depreciation. In 2009, we recorded net income of (Won)840 billion under U.S. GAAP compared to net income of (Won)610 billion under Korean GAAP, primarily because of difference in the treatment of service installation fees, reversal of goodwill amortization and depreciation. In 2010, we recorded net income of (Won)1,196 billion under U.S. GAAP compared to net income of (Won)1,193 billion under Korean GAAP. Total equity under U.S. GAAP is lower than under Korean GAAP by
(Won)478 billion as of December 31, 2008, (Won)211 billion as of December 31, 2009 and (Won)396 billion as of December 31, 2010.

For further discussion of the principal differences between Korean GAAP and U.S. GAAP as they relate to us, see Note 38 to the
Consolidated Financial Statements.

Recent Accounting Pronouncements in U.S. GAAP

In September 2006, the Financial Accounting Standards Board (FASB) issued enhanced guidance for using fair value to measure assets and
liabilities by establishing a common definition of fair value, providing a framework for measuring fair value under GAAP, and expanding the disclosure requirements about fair value measurements. In February 2008, the FASB deferred the adoption of
such guidance for one year for nonfinancial assets and nonfinancial liabilities that are recognized or disclosed at fair value in the financial statements on a non-recurring basis. We adopted the fair value guidance for nonfinancial assets and
nonfinancial liabilities on January 1, 2009 with no material impact to our consolidated financial statements. In April 2009, the FASB issued additional guidance on fair value, which provided: (a) additional application guidance for
estimating fair value when the volume and activity for the asset or liability have greatly decreased and (b) indicators for identifying transactions that are not considered orderly. The additional guidance was effective for interim periods
ending after June 15, 2009, with early adoption permitted for periods ending after March 15, 2009. We adopted the provisions in 2009 with no material impact to our consolidated financial statements.

In December 2007, the FASB issued an amended accounting guidance on business combinations. The guidance revises the method of accounting for a
number of aspects of business combinations including acquisition costs, contingencies (including contingent assets, contingent liabilities and contingent purchase price) and post-acquisition exit activities of acquired businesses. We adopted the
guidance in 2009 with no material impact to our consolidated financial statements.

In December 2007, the FASB issued new accounting
guidance on noncontrolling interests in consolidated financial statements. The new accounting guidance requires that a noncontrolling interest in the equity of a subsidiary be accounted for and reported as equity, provides revised guidance on the
treatment of net income and losses attributable to the noncontrolling interest and changes in ownership interests in a subsidiary and requires additional disclosures that identify and distinguish between the interests of the controlling and
noncontrolling owners. We retrospectively adopted the presentation and disclosure requirements of the new guidance. The adoption of the new guidance did not have a material effect on our consolidated financial statements.

In March 2008, the FASB issued enhanced guidance for disclosures about derivative instruments and hedging activities by expanding the disclosure
requirements regarding: (1) how and

why an entity uses derivative instruments; (2) how derivative instruments and related hedged items are accounted for; and (3) how derivative instruments and related hedged items affect
an entitys financial position, financial performance, and cash flows. In addition, this guidance requires qualitative disclosures about objectives and strategies for using derivatives described in the context of an entitys risk
exposures, quantitative disclosures about the location and fair value of derivative instruments and associated gains and losses, and disclosures about credit-risk-related contingent features in derivative instruments. We adopted the new guidance in
2009 with no material impact to our consolidated financial statements.

In April 2008, the FASB amended the factors that we should
consider when developing renewal or extension assumptions used in the determination of useful lives of intangible assets. These assumptions should be consistent with the expected cash flow method used to measure the fair value of intangible assets.
The amended guidance was applicable prospectively to intangible assets acquired after January 1, 2009 with no material impact to our consolidated financial statements.

In November 2008, the FASB ratified guidance approved by the Emerging Issues Task Force addressing how the business combination and noncontrolling interest guidance issued by the FASB might impact the accounting
for equity method investments. The guidance was effective prospectively for new investments acquired in fiscal years beginning on or after December 15, 2008. We adopted the guidance in 2009 with no material impact on our consolidated financial
statements.

In July 2009, the FASB issued the FASB Accounting Standard Codification (Codification or ASC),
which became the single source of authoritative U.S. GAAP. Following the Codification, the FASB will not issue any new standard in the form of Statements, FASB Staff Positions or Emerging Issues Task Force Abstracts. Instead, it will issue
Accounting Standards Updates (ASU), which will serve to update the Codification, provide background information about the guidance and provide the basis for conclusions on the changes to the Codification. We adopted the Codification, as
required, for annual periods ending after September 15, 2009. As a result, references to accounting literature contained in our financial disclosures have been updated to reflect the new ASC structure.

In June 2009, the FASB amended the consolidation rules related to Variable Interest Entities (VIEs). The new rules expand the primary
beneficiary analysis to incorporate a qualitative review of which entity controls and directs the activities of the VIE. The amendments also modify the rules regarding the frequency of ongoing reassessments of whether a company is the primary
beneficiary. Under the revised guidance, we are required to perform ongoing reassessments as opposed to only when certain triggering events occur, as was previously required. We adopted the new guidance in 2010 with no material impact on our
consolidated financial statements.

In October 2009, the FASB issued ASU No. 2009-13, Multiple-Deliverable Revenue
Arrangements (ASU No. 2009-13). The update addresses how revenues should be allocated among all products and services included in sales arrangements. It establishes a selling price hierarchy for determining the selling price
of each product or service, with vendor-specific objective evidence at the highest level, third-party evidence of selling price at the intermediate level, and the best estimate of the selling price at the lowest level. It replaces fair
value with selling price in revenue allocation guidance, eliminates the residual method as an acceptable allocation method and requires the use of the relative selling price method as the basis for allocation. It also significantly
expands the disclosure requirements for such arrangements, including, potentially, certain qualitative disclosures. ASU No. 2009-13 will be effective prospectively for sales entered into or materially modified in fiscal years beginning on or
after June 15, 2010. The FASB permits early adoption of ASU No. 2009-13, applied retrospectively, to the beginning of the year of adoption. We adopted ASU No. 2009-13 in 2010 with no material impact on our consolidated financial
statements.

In October 2009, the FASB issued ASU No. 2009-14, Certain Revenue Arrangements That
Include Software Elements (ASU No. 2009-14). The update clarifies the guidance for allocating and measuring revenue, including how to identify software that is out of the scope. The update also amends accounting and reporting
guidance for revenue arrangements involving both tangible products and software that is more than incidental to the tangible product as a whole. Such types of software and hardware will be outside of the scope of software revenue
guidance, and the hardware components will also be outside of the scope of software revenue guidance and may result in more revenue recognized at the time of the hardware sale. Additional disclosures will discuss allocation of revenue to products
and services in sales arrangements and the significant judgments applied in the revenue allocation method, including impacts on the timing and amount of revenue recognition. ASU 2009-14 will be effective prospectively for revenue arrangements
entered into or materially modified in fiscal years beginning on or after June 15, 2010. ASU No. 2009-14 has the same effective date, including early adoption provisions, as ASU No. 2009-13. We must adopt ASU No. 2009-14 and ASU
No. 2009-13 at the same time. We adopted ASU No. 2009-14 in 2010 with no material impact on our consolidated financial statements.

In December 2009, the FASB issued ASU No. 2009-16, Transfers and Servicing (ASU No. 2009-16). This update removes the concept of a qualifying special-purpose entity
(QSPE) and creates more stringent conditions for reporting a transfer of a portion of financial asset as sale. To determine if a transfer is to be accounted for as sale, the transferor must assess whether it and all of the entities
included in its consolidated financial statements have surrendered control of the assets. This update became effective on January 1, 2010, with adoption applied prospectively for transfers that occur on and after the effective date. The
elimination of the QSPE concept required an entity to retrospectively assess all current off-balance sheet QSPE structures for consolidation under ASC Topic 810, Consolidation, and record a cumulative-effect adjustment to retained
earnings for any consolidation change. Retrospective application of ASU No. 2009-16, particularly the QSPE removal, was assessed as part of the analysis required from ASU No. 2009-17, Improvements to Financial Reporting by
Enterprises Involved with Variable Interest Entities.

In December 2009, the FASB issued ASU No. 2009-17. This update
addressed the primary beneficiary assessment criteria for determining whether an entity is required to consolidate a VIE. This update requires an entity to determine whether it is the primary beneficiary by performing a qualitative assessment,
rather than using the quantitative-based model required under the previous accounting guidance. The qualitative assessment consists of determining whether the entity has both the power to direct the activities that most significantly impact the
VIEs economic performance and has the right to receive benefits or obligation to absorb losses that could potentially be significant to the VIE. This update became effective on January 1, 2010. We adopted ASU No. 2009-16 and
No. 2009-17 in 2010 with no material impact on our consolidated financial statements.

In January 2010, the FASB amended the
disclosure guidance related to fair value measurements. The amended disclosure guidance requires new fair value measurement disclosures and clarifies existing fair value measurement disclosure requirements. The amended disclosure guidance related to
disclosures about purchases, sales, issuances and settlements of Level 3 instruments became effective for fiscal years beginning after December 15, 2010. The remaining amended disclosure guidance will be effective for annual reporting periods
beginning after December 15, 2009. We adopted this guidance in 2010 with no material impact on our financial statements.

In
January 2010, the FASB issued authoritative guidance for improving disclosures about fair value measurements, which requires new and amended disclosure requirements for classes of assets and liabilities, inputs and valuation techniques and transfers
between levels of fair value measurements and accounting for distributions to shareholders with components of stock and cash,



69

##### Table of Contents

which clarifies the accounting for distributions to shareholders that offer them the ability to elect to receive their entire distribution in cash or shares of equivalent value. This guidance
became effective in January 2010. We adopted this guidance in 2010 with no material impact on our consolidated financial statements.

In
February 2010, the FASB issued ASU 2010-09 to amend ASC 855, Subsequent Events to address certain implementation issues. The amendments remove the requirement for an SEC filer to disclose a date in both issued and revised financial statements.
Revised financial statements include financial statements revised as a result of either correction of an error or retrospective application of U.S. GAAP. Additionally, the FASB has clarified that if the financial statements have been revised, then
an entity that is not an SEC filer should disclose both the date that the financial statements were issued or available to be issued and the date the revised financial statements were issued or available to be issued. The amendment is effective for
interim or annual periods ending after June 15, 2010. We adopted this guidance in 2010 with no material impact on our consolidated financial statements.

In July 2010, the FASB issued ASU 2010-20 to provide financial statement users with greater transparency about an entitys allowance for credit losses and the credit quality of its financing receivables. This
amendment is intended to provide additional information to assist financial statement users in assessing an entitys credit risk exposures and evaluating the adequacy of its allowance for credit losses. The disclosures as of the end of a
reporting period are effective for interim and annual reporting periods ending on or after December 15, 2010. The disclosures about activity that occurs during a reporting period are effective for interim and annual reporting periods beginning
on or after December 15, 2010. We adopted ASU 2010-20 in 2010 and disclosed the additional information related to credit risk in our consolidated financial statements.

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 (Won)2,000 billion, 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 all directors is up to three years, but the term is extended to the close of the annual shareholders meeting convened
with respect to the last fiscal year of the term. If the term of office for the director ends before the close of the annual general meeting of shareholders convened with respect to the last fiscal year within such term of office and a new director
is appointed, the term of office for such new director will be the 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 not less 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. Our Outside Director Candidate Nominating Committee nominates outside director candidates for appointment at the general shareholders meeting.

Upon the request of any director, 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 one year.

Under our articles of incorporation, the Chief Executive Officer Candidate Nominating Committee must submit a draft management contract between the company and the candidate covering the management objectives of
the company to the shareholders meeting at the time of nomination of the candidate to the meeting. When the draft management contract has been approved at the shareholders meeting, the company enters into such management contract with
the Chief Executive Officer. In such case, the chairperson of the Chief Executive Officer Candidate Nominating Committee, on behalf of the company, signs the management contract.

The board of directors may conduct performance review discussions to determine if the new Chief Executive Officer performed his or her duties under
the management contract, or hire a professional evaluation agency for such purpose. If the board of directors determines, based on the results of the performance review, that the new Chief Executive Officer has failed to achieve the management
goals, it may propose to dismiss the Chief Executive Officer at a shareholders meeting.

Senior Management

Our executive officers consist of President, Senior Executive Vice President, Executive Vice Presidents and Senior Vice Presidents. The executive
officers other than the non-independent directors are appointed by the Chief Executive Officer and may serve up to three years.

The
current executive officers are as follows:

Item 6.B.Compensation

Compensation of Directors and Executive Officers

In 2010, the total amount of salaries, bonuses (including long-term performance-based incentives for directors) and allowances paid and accrued to all directors and executive officers of KT Corporation for services
in all capacities was approximately (Won)42 billion. The aggregate amount accrued by us to provide retirement benefits to such persons was (Won)6 billion in 2010. 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, 2010, 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.

Corporate Governance Committee

The
Corporate Governance Committee is comprised of four outside directors and one standing director, Choon-Ho Lee, E. Han Kim, Jeung-Soo Huh, Hae-Bang Chung 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. 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, Jeung-Soo Huh, Choon-Ho Lee, Jong-Hwan Song and Chan-Jin Lee. The chairperson is Jeung-Soo Huh. The committees
duties include prior review of the Chief Executive Officers management goals, terms and conditions proposed for inclusion in the employment 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

(Won)30 billion, making investments and providing guarantees up to (Won)30 billion, the disposal and sale of stocks of our subsidiaries, which stocks have a market value of between (Won)15 billion and (Won)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 (Won)100 million to (Won)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, Jong-Hwan Song, Chan-Jin Lee, Hyun-Nak Lee and Byong Won Bahk. The chairperson is Jong-Hwan Song. 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 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 E. Han Kim, Hae-Bang Chung, Hyun-Nak Lee and Byong Won Bahk. The chairperson is Hae-Bang Chung. Members of the committee are elected by our shareholders at the shareholders
meeting. Our internal and external auditors report directly to the committee.

Item 6.D.Employees

On a non-consolidated basis, we had 31,155 employees as of December 31, 2010, compared to 30,841 employees as of December 31, 2009 and
35,063 employees as of December 31, 2008. Prior to the merger with KT Corporation, KTF had 2,560 employees as of December 31, 2008.

The
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 2008, 1,141 employees retired under KT Corporations voluntary early retirement plan.

In 2009, we had a voluntary early retirement plan where we received applications from employees who had been employed by us for more than 20 years.
In addition, we held a special voluntary early retirement program in the fourth quarter of 2009 where 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. In aggregate, 6,515 employees retired in 2009 under the voluntary early retirement plan and the special voluntary early retirement program.

In 2010, 123 employees retired under KT Corporations voluntary early retirement plan. We did not have a special voluntary early retirement
program in 2010.

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, 2010, about 78.6% of all 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.

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

##### Table of Contents

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 will become 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. 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 1.56% of our issued shares as of December 31,
2010.

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 January 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 January 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, with a total
unfunded portion of approximately (Won)350 billion as of December 31, 2010. Our employees have the option of choosing either the defined
benefit plan or the defined contribution plan. 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
(Won)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 favor of us on all claims in May 2011, and the plaintiffs filed an appeal in June 2011.

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 (Won)10 billion. We paid such fines to the Korea Communications Commission and implemented its corrective orders.

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.

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.

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 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.

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.

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.

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.

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.

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
(Won)5,000                   |  | (Won)           | 5     | 
|(Won)5,000 to less than (Won)10,000    |  | (Won)           | 10    | 
|(Won)10,000 to less than (Won)50,000   |  | (Won)           | 50    | 
|(Won)50,000 to less than (Won)100,000  |  | (Won)           | 100   | 
|(Won)100,000 to less than (Won)500,000 |  | (Won)           | 500   | 
|(Won)500,000 or
more                   |  | (Won)           | 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 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.

Starting from
May 1, 1996, foreign investors were 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.

As of December 30, 1997, foreign investors were 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. The Government
announced on February 8, 1998 its plans for the liberalization of the money market with respect to investment in money market instruments by foreigners in 1998. According to the plan, foreigners have been permitted to invest in money market
instruments issued by corporations, including commercial

paper, starting February 16, 1998 with no restrictions as to the amount. Starting May 25, 1998, foreigners have been 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 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 (Won)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 (Won)5,000 per share (Common Shares) and shares of non-voting preferred stock, par value
(Won)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, 2010, 261,111,808 Common Shares were issued, of which 17,895,964 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



90



---

##### Table of Contents

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 our capital
surplus reserve and 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 legal reserve an amount equal to at least 10% of the cash portion of the dividend or
unless we have accumulated a legal reserve of not less than one-half of our stated capital. We may not use legal reserve to pay cash dividends but may transfer amounts from legal reserve to capital stock or use 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 our capital surplus or 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 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, 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.
| | - |  | ---------------------------------------------------------------------------------------------------------

In addition, we may issue convertible bonds or bonds with warrants, each up to an aggregate principal amount of (Won)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, 2010, 1.56% 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, all of conditions (i) to (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 Korea Communications Commission
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;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | 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.
| | - |  | --------------------------------------

Holders of Non-Voting Shares may request a general meeting of shareholders only after the Non-Voting Shares become entitled to vote or are enfranchised, as described under Voting Rights below.

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, unless enfranchised, 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.

##### Table of Contents

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 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. In addition, if we are
unable to pay dividends on Non-Voting Shares as provided in our articles of incorporation, the holders of Non-Voting Shares will become enfranchised and will be entitled to exercise voting rights until those dividends are paid. The holders of
enfranchised Non-Voting Shares have the same rights as holders of Common Shares to request, receive notice of, attend and vote at a general meeting of shareholders.

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 absentiaby 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.

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 dissenters 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 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 non-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 non-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

We may not
acquire our own Shares except in limited circumstances, such as a reduction in capital. In addition, pursuant to the Financial Investment Services and Capital Markets Act, we may acquire Shares only by (i) purchasing on the KRX KOSPI Market,
(ii) a tender offer, or (iii) receiving Shares returned to 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, subject to certain procedural requirements, provided that, in case of acquisition of our own Shares by us for the purpose of
cancellation, the aggregate purchase price may not exceed the total amount available for distribution of dividends at the end of the preceding fiscal year minus certain reserves.

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

As of December 31, 2010, there were 17,895,964 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

The Merger Agreement between KT Corporation and KTF

On January 20, 2009, KTF and KT Corporation entered into a merger agreement, pursuant to which KTF merged into KT Corporation on June 1, 2009. KTF common stockholder received 0.7192335 share of KT
Corporation common stock for every one share of KTF common stock that they owned. KT Corporation waived issuance of any merger consideration in respect of all of the outstanding shares of KTF common stock held by KT Corporation immediately prior to
the merger.

##### Table of Contents

Pursuant to the merger agreement, all of the assets, liabilities, rights and obligations (including
contractual rights and obligations) of KTF were comprehensively succeeded by KT Corporation. The employees of KTF became employees of KT Corporation as a result of the merger, and the obligations to pay severance payments to those employees were
succeeded by KT Corporation.

Under Korean law, holders of shares of KT Corporation or KTF common stock who opposed the merger were
entitled to exercise their appraisal rights to purchase their shares, which were set at (Won)38,535 for each share of KT Corporation common
stock properly submitted to KT Corporation for appraisal and (Won)29,284 for each share of KTF common stock properly submitted to KTF for
appraisal.

KT Corporation delivered 700,108 shares of its newly issued common stock (par value (Won)5,000) and 45,629,480 shares of its treasury shares (par value (Won)5,000) to KTF stockholders listed on the stockholder registry of KTF as of the date of the merger. See Item 5. Operating and Financial Review and ProspectsItem 5.A. Operating
ResultOverviewMerger of KTF into KT Corporation.

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.

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



97



---

##### Table of Contents

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.

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

##### Table of Contents

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 direct investment as defined in the Foreign Investment Promotion Law;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | 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.

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 deemed to be a foreign direct investment pursuant to the Financial Investment Services and Capital Markets 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

##### Table of Contents

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 must 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 and will act as a standing proxy to exercise shareholders rights or perform any matters related to
the foregoing activities if the foreign investor does not perform these activities himself. However, a foreign investor may be exempted from complying with these standing proxy rules with the approval of the Governor of the Financial Supervisory
Service in cases deemed inevitable by reason of conflict between laws of Korea and the home country of the foreign investor.

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.

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



100

##### Table of Contents

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.

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
| | - |  | --------------------------------------------

##### Table of Contents

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 tax 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.

If 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.

##### Table of Contents

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 recently 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 not constitute share certificates subject to the securities transaction tax. In 2008, the case 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;

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;
| | - |  | -------------------------------------------



| |  |  | a U.S. domestic corporation; or
| | - |  | -------------------------------



| |  |  | subject to U.S. federal income tax on a net income basis with respect to income from the 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.

##### Table of Contents

Subject to certain exceptions for short-term and hedged positions, the U.S. dollar amount of
dividends received by an individual prior to January 1, 2013 with respect to the ADSs and common stock will be subject to taxation at a maximum rate of 15% 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 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-linked securities. Following evaluation of these positions, we selectively enter into derivative financial instruments to manage the related risk exposures. 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 only for hedging purposes.

##### Table of Contents

For details of the assets and liabilities recorded relating to our derivative contracts outstanding
as of December 31, 2009 and 2010, see Note 13 to the Consolidated Financial Statements. We recognized a valuation gain of (Won)18 billion
and a valuation loss of (Won)191 billion in 2009 and a valuation gain of (Won)40 billion and a valuation loss of (Won)48 billion in 2010.

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.

In 2009 and 2010 we entered into various currency-related derivative contracts with various financial institutions, including the following:

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 with Merrill Lynch and others 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 described above.

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 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

Security Holders and Use of Proceeds

Not applicable.

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, 2010. 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 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, 2010 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, 2010.

Samil
PricewaterhouseCoopers, an independent registered public accounting firm, which also audited our consolidated financial statements as of, and for the year ended December 31, 2010, 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

Changes in Internal Control Over Financial Reporting

Audit Committee Pre-Approval Policies and Procedures

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.

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.

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.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of

KT
Corporation

In our opinion, the accompanying consolidated statement of financial position and the related consolidated statements
of income, 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, 2010 and the results of their operations and their cash
flows for the year then ended in conformity with accounting principles generally accepted in the Republic of Korea. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of
December 31, 2010, 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 audit. We conducted our audit
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 audit 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.

Accounting principles generally accepted in the Republic of Korea vary in certain significant respects from accounting principles generally accepted in the United States of America. Information relating to the
nature and effect of such differences is presented in Note 38 to the consolidated financial statements.

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.

for the years ended December 31, 2009 and 2008. These financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on these financial statements based on our 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the
financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable
basis for our opinion.

In our opinion, such 2009 and 2008 consolidated financial statements present fairly, in all material respects,
the financial position of KT Corporation and subsidiaries at December 31, 2009, and the results of their operations and their cash flows for the years ended December 31, 2009 and 2008, in conformity with accounting principles generally accepted in
the Republic of Korea.

Accounting principles generally accepted in the Republic of Korea vary in certain significant respects from
accounting principles generally accepted in the United States of America. Information relating to the nature and effect of such differences is presented in Note 38 to the consolidated financial statements.

Notes to Consolidated Financial Statements

December 31, 2010, 2009 and 2008

1.    General information

KT Corporation (the Controlling Company) commenced operations on January 1, 1982, when it spun off from the Korea Communications
Commission (formerly the Korean Ministry of Information and Communications) to provide telephone services and to engage in the development of advanced communications services under the Act of Telecommunications of Korea.

On October 1, 1997, upon the announcement of the Government-Investment Enterprises Management Basic Act and the Privatization Law, the
Controlling Company became a government-funded institution under the Commercial Code of Korea.

On December 23, 1998, the
Controlling Companys shares were listed on the Korea Exchange.

On May 29, 1999, the Controlling Company issued 24,282,195
additional shares and issued American Depository Shares (ADS), representing new shares and government-owned shares, at the New York Stock Exchange and the London Stock Exchange. On July 2, 2001, the ADS representing 55,502,161 government-shares
were issued.

In 2002, the Controlling Company acquired 60,294,575 government-owned shares in accordance with the Korean
governments privatization plan. As of December 31, 2010, the Korean government did not own any share in the Controlling Company.

On June 1, 2009, the Controlling Company, as the surviving entity, merged with KT Freetel Co., Ltd. to have competitive advantages in the global trends of convergence between fixed and mobile communication.

A summary of financial data of the major consolidated subsidiaries as of and for the year ended December 31,
2010, is presented prior to the elimination of intercompany transactions. The financial data of New Telephone Company, Inc. are based on the consolidated financial statements and the financial data of all others are based on non-consolidated
financial statements.

3.    Summary of Significant Accounting Policies

The following is a summary of significant accounting policies followed by the Controlling Company and its subsidiaries (collectively referred to as
the Company) in the preparation of its financial statements. These policies have been consistently applied to all the years presented, unless otherwise stated.

Basis of Presentation

The Company maintains its accounting records in Korean won and
prepares statutory financial statements in Korean language (Hangul) in conformity with the accounting principles generally accepted in the Republic of Korea. Certain accounting principles applied by the Company that conform with financial accounting
standards and accounting principles in the Republic of Korea may not conform with generally accepted accounting principles in other countries. Accordingly, these consolidated financial statements are intended for use by those who are informed about
Korean accounting principles and practices. The accompanying consolidated financial statements have been condensed, restructured and translated into English from the Korean language financial statements.

Principles of Consolidation

The fiscal year end of the consolidated subsidiaries is the same as that of the Controlling Company, except for KT Internal Venture Fund No.2 and
KTC Media Contents Fund 1. If the fiscal year end of a consolidated subsidiary is different from that of the Controlling Company, the consolidated financial statements are prepared based on the subsidiarys reliable financial statements as of
the fiscal year end of the Controlling Company. Differences in accounting policy between the Company and its consolidated subsidiaries are adjusted during consolidation.

The investment accounts of the Controlling Company and corresponding capital accounts of the subsidiaries are eliminated as of the fiscal year end of the subsidiaries closest to date when the Controlling Company
acquires control in the subsidiaries. All significant intercompany transactions and balances with consolidated subsidiaries have been eliminated during consolidation.

When the Company has control over a subsidiary, the Company records differences between the initial investment accounts and corresponding capital accounts of subsidiaries as goodwill or negative goodwill. The
goodwill is amortized using the straight-line method over the estimated useful lives, which range from four to ten years. The negative goodwill relating to the expected expense or loss in the future is reversed as a gain when the related expense or
loss is actually incurred, whereas the negative goodwill not relating to the certain future expense is amortized over the weighted average useful lives of depreciable non-monetary assets of an acquiree and the amounts of this negative goodwill in
excess of the fair value of the total non-monetary assets of an acquiree are recorded as a gain as of the acquisition date. In addition, the differences between the additional investment in the subsidiaries and net assets of the subsidiaries
attributable to subsequently acquired controlling interest and differences between the acquisition cost of the investments in the subsidiaries and changes in net assets of the subsidiaries due to certain equity transactions of the subsidiaries
including capital increase with consideration are reflected in the capital surplus or capital adjustment.

When the Company gains
significant influence over the equity-method investees, the excess of the acquisition cost of an investment in an investee over the Companys share of the fair value of the identifiable net assets acquired is amortized using the straight-line
method over its estimated useful life, not exceeding 20 years. When acquisition cost of investments in an investee is less than the Companys interest on the fair value of the identifiable net assets acquired, the investment differences
relating to the expected expense or loss in the future is reversed as a gain when the related expense or loss is actually incurred. The investment differences not relating to the certain future expense up to fair value of depreciable non-monetary
assets of an investee is amortized over the weighted average useful lives of depreciable non-monetary assets of an investee and the remaining amounts of investment difference in excess of the fair value of the total non-monetary assets of an
investee are recorded as a gain as of the acquisition date.

Unrealized gains or losses included in inventories and other assets as a
result of intercompany transactions are eliminated based on the average gross profit ratio of the corresponding company. Unrealized gains or losses, arising from sales by the Controlling Company to the consolidated subsidiaries, are fully eliminated
and charged to the equity of the Controlling Company. Unrealized gains or losses, arising from sales by the consolidated subsidiaries to the Controlling Company, or sales between consolidated subsidiaries, are fully eliminated, and charged to the
equity of the Controlling Company and the minority interests, based on the percentage of ownership. Unrealized gains or losses, arising from the transactions between the Company and equity method investees are eliminated in proportion to the
Companys ownership and reflected in equity-method investments.

Minority interest

The Company records the equity of the consolidated subsidiaries, which is not included in the equity of the Controlling Company, as minority
interest in consolidated subsidiaries. In addition, even if the minority interest has a deficit balance, the total comprehensive income is attributed to the owners of the parent and to the minority interests.

Reclassifications of Prior Year Financial Statements

Certain reclassifications have been made in 2008 and 2009 consolidated financial statements to conform to 2010 consolidated financial statement presentation. Such reclassifications did not have an effect on the
shareholders equity and net income of the Company as of and for the years ended December 31, 2008 and 2009.

Revenue
Recognition

Revenue is the gross inflow of economic benefits arising in the ordinary course of the Companys activities
and is measured as the fair value of the consideration received or receivable for the sale of goods and services in the said ordinary course of the Companys activities. Revenue is shown as net of value-added tax, sales discounts and sales
returns. The Company recognizes revenue when the amount of revenue can be reliably measured, and it is probable that future economic benefits will flow into the Company. 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.

Revenue from the sale of goods is recognized when the significant risks and rewards of ownership of goods are transferred to the buyer. Revenue
from the rendering of services is recognized under the percentage-of-completion method, under which revenue is generally recognized based on the costs incurred to date as a percentage of the total estimated costs to be incurred.

The Company recognizes revenues from construction contracts using the percentage-of-completion method to determine the amounts to be recognized as
revenues in a given period. The stage of completion is measured using the percentage of the total contract costs incurred up to the date of statement of financial position over the total estimated costs for each contract. When the outcome of a
construction contract cannot be estimated reliably, the contract revenue is recognized only to the extent of contract costs incurred that are likely to be recoverable, and contract costs incurred for the period is recognized as an expense.

Interest income is recognized using the effective interest method. Dividend income is recognized when the rights to receive such
dividends and amounts thereof are determined.

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand and in banks, and financial instruments with maturity of three months or less at the time of
purchase. These financial instruments are readily convertible into cash without significant transaction costs and bear low risks from changes in value due to interest rate fluctuations.

Allowance for Doubtful Accounts

The Company provides an allowance for doubtful accounts and notes receivable. Allowances are calculated based on the estimates made through a reasonable and objective method.

Inventories

The quantities of inventories are determined using the perpetual method and periodic inventory count, while the costs of inventories are determined using the moving-weighted average method. Goods-in-transit and
land use the specific identification method. Inventories are stated at the lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less applicable variable selling expense.
Replacement cost is used for the estimate of the net realizable value of raw materials. Market prices of merchandise and supplies are net realizable value and replacement cost, respectively. If, however, the circumstances which caused the valuation
loss cease to exist, the valuation loss is reversed up to the original carrying amount before valuation. The said reversal is deducted from cost of sales.

Investments in Securities

Costs of debt securities and equity securities are
determined using the specific identification method and the moving-weighted average method, respectively. Investments in equity securities or debt securities are classified into trading securities, available-for-sale securities and held-to-maturity
securities, depending on the acquisition and holding purpose. Investments in equity securities of companies, over which the Company exercises a significant control or influence, are recorded using the equity method of accounting. Trading securities
are classified as current assets while available-for-sale securities and held-to-maturity securities are classified as long-term investments, excluding those securities that mature or are certain to be disposed of within one year, which are then
classified as current assets.

Held-to-maturity securities are measured at amortized cost while available-for-sale and trading
securities are measured at fair value. However, non-marketable securities, classified as available-for-sale securities, are carried at cost when the fair values are not readily determinable.

Gains and losses related to trading securities are recognized in the income statement, while unrealized gains and losses of available-for-sale
securities are recognized under other comprehensive income and expense. Realized gains and losses on available-for-sale securities are recognized in the income statement.

Equity-Method Investments

Company reflects any changes in the equity of its
equity-method investments after the initial purchase date. Under the equity method, the Company records changes in its proportionate ownership in the book value of the investee in current operations, as capital adjustments or as adjustments to
retained earnings, depending on the nature of the underlying change in the book value of the investee. All other changes in equity should be accounted for under other comprehensive income and expense.

Property, Plant and Equipment

Property, plant and equipment are stated at cost, which includes acquisition cost, production cost and other costs required to prepare the asset
for its intended use. It also includes the present value of the estimated cost of dismantling and removing the asset, and restoring the site after the termination of the assets useful life, provided it meets the criteria for recognition of
provisions.

Expenditures incurred after the acquisition or completion of assets are capitalized if they enhance the value of
the related assets over their recently appraised value or extend the useful life of the related assets. Routine maintenance and repairs are charged to expense as incurred.

Intangible Assets

Intangible assets are stated at cost, which includes acquisition
cost, production cost and other costs required to prepare the asset for its intended use. Intangible assets are stated net of accumulated amortization calculated by straight-line method based on following estimated useful lives:



|                               |  |

Development costs which are individually identifiable and directly related to a new technology or to new products
which carry probable future benefits are capitalized as intangible assets. Amortization of development cost begins at the commencement of the commercial production of the related products or use of the related technology.

Goodwill represents the excess of the cost of an acquisition over the fair value of the Controlling Companys share in the net identifiable
assets of the acquired subsidiary or associate at the date of acquisition.

Capitalization of Interest Expense

The Company capitalizes the interest it incurs on borrowings used to finance the cost of manufacturing, acquisition, and construction of inventory
and property, plant, and equipment that require more than one year to complete from the initial date of manufacture, acquisition, and construction.

Government Grants

The Company recognizes government grants, which are to be repaid, as liabilities. The government grants and donations, which are intended to be
used for the acquisition of certain assets, are deducted from the cost of the acquired assets. The government grants or donations, received to compensate for specific expenses, are offset against the related expenses. Other government grants or
donations, for which the use or purpose is not specified, are recorded as gains from assets received, and are recognized in current operations. Prior to the acquisition of the assets specified, the grant or donation is recorded as deduction from the
assets granted. When the related assets are acquired, the amounts are recognized as a deduction from the account under which the assets acquired are recorded and offset against the depreciation expense over the period of the assets useful
live. After the disposal of the assets specified by the grant or donation, the remaining amounts are deducted or added to the assets disposal gain and loss.

Impairment of Assets

When the book value of an asset is significantly greater than its
recoverable value due to obsolescence, physical damage or an abrupt decline in the market value of the asset, the said decline in value is deducted from the book value to agree with recoverable amount and is recognized as an asset impairment loss
for the period. When the recoverable value subsequently exceeds the book value, the impairment amount is recognized as gain for the period to the extent that the revised book value does not exceed the book value that would have been recorded without
the impairment. Reversal of impairment of goodwill is not allowed.

Derivatives

All derivative instruments are accounted for at their fair value according to the rights and obligations associated with the derivative contracts.
The resulting changes in fair value of derivative instruments are recognized either under the income statement or shareholders equity, depending on whether the derivative instruments qualify as a cash flow hedge. Fair value hedge accounting is
applied to a derivative instrument purchased with the purpose of hedging the exposure to changes in the fair value of an asset or a liability or a firm commitment that is attributable to a particular risk. The resulting changes in the fair value of
derivatives that are designated and qualify as cash flow hedges are recognized under the shareholders equity under accumulated other comprehensive income and expense.

Income Tax and Deferred Income Tax

Income tax expense includes the current income tax
under the relevant income tax law and the changes in deferred tax assets or liabilities. Deferred tax assets and liabilities represent temporary differences between financial reporting and the tax bases of assets and liabilities. Deferred tax assets
are recognized for temporary differences which will decrease future taxable income or operating loss to the extent that it is probable that future taxable income will be available against which the temporary differences can be utilized. Deferred tax
effects applicable to items in the shareholders equity are directly reflected in the shareholders equity.

Discounts
on Debentures

Discounts on debentures are amortized over the term of the debentures using the effective interest rate method.
Amortization of the discount is recorded as part of interest expense.

Accrued Severance Benefits

Employees and directors with at least one year of service are entitled to receive a lump-sum payment upon termination of their employment with the
Company based on their length of service and rate of pay at the time of termination. Accrued severance benefits represent the amount which would be payable assuming all eligible employees and directors were to terminate their employment as of the
date of statement of financial position.

The domestic subsidiaries have partially funded their accrued severance benefits through
severance insurance deposits with an insurance company. Deposits made by the subsidiaries are recorded as deductions from accrued severance benefits. The excess portion of deposits over accrued severance benefits is recorded as other investments.

In addition, the domestic subsidiaries deposit a certain portion of severance benefits to National Pension Service according to
National Pension Law. The deposit amount is recorded as a deduction from accrued severance benefits.

Overseas subsidiaries accrue
employees retirement benefits according to the local regulations in which they operate.

Provisions and Contingent
Liabilities

When it is probable that an outflow of economic benefits will occur due to a present obligation resulting from a
past event, and whose amount is reasonably estimable, a corresponding amount of provision is recognized in the financial statements. However, when such outflow is dependent upon a future event, is not certain to occur, or cannot be reliably
estimated, a disclosure regarding the contingent liability is made in the notes to the financial statements.

Finance Leases

i) The Company as Lessee

The Company accounts for lease transactions as either operating lease or finance lease, depending on the terms of the lease agreement. A finance lease is a lease that transfers substantially all the risks and
rewards incidental to the ownership of an asset. The lower of the present value of minimum lease payments and the fair value of the lease asset is recognized as the value of the finance lease asset and liability. Annual minimum lease payments,
excluding residual value, are allocated to interest expense, or for the redemption of capital lease liability using the effective interest method.

ii) The Company as Lessor

The Company accounts for lease transactions as finance lease for
leases that transfer substantially all of the risks and benefits of ownership of the lease asset to the lessee. The Company recognizes the amount equivalent to the net investment in the lease asset as finance lease receivable. The Company recognizes
interest income over lease term using systematic and reasonable method. Interest income is calculated for net finance lease receivable based on effective interest rate. The lease receipt is recorded separately as collection of finance lease
receivable and interest income.

Operating Leases

i) The Company as Lessee

An operating lease is a lease that does not transfer substantially all the risks and rewards incidental to ownership of an asset. The annual
minimum lease payments, less guaranteed residual value, are charged to expense on a regular basis over the lease term.

ii) The Company as Lessor

The Company accounts for operating leases as leases that do not transfer substantially all of the risks and benefits of ownership of the lease
asset to the lessee. The lease assets are recognized as tangible or intangible assets depending on the nature of the lease assets. The annual minimum lease receipts, less guaranteed residual value, are recognized as revenue over the lease term.

Valuation of Assets and Liabilities at Present Value

Receivables and payables resulting from long-term installment payment transactions, long-term cash loans or other similar borrowings, are valued at
their present values, discounted at an appropriate discount rate when the difference between the nominal value and present value is material. The present value discounts are amortized or recovered using the effective interest rate method and are
recognized as interest income or expense over the term of the contract.

Translation of Assets and Liabilities Denominated in
Foreign Currencies

Monetary assets and liabilities denominated in foreign currencies are translated into Korean won at the
rates of exchange in effect at the date of statement of financial position, and the resulting translation gains and losses are recognized in current operations.

Currency Translation for Foreign Operations

Assets and liabilities of a foreign
subsidiary or company subject to the equity method of accounting for investments are translated into Korean won at the rates of exchange in effect at the date of statement of financial position, while equity accounts are translated at historical
rates, except for the change in retained earnings during the year (current period income or loss) which is the result of the income statement translation process, and income statement accounts at the average rate over the period. Net translation
adjustments are allocated to the controlling interest and minority interest and the portions allocated to the controlling interest are accounted for as gain(loss) on translation of foreign operation included in the other comprehensive income. Net
translation adjustment of equity-method investees are accounted for as comprehensive income(expensive) of equity-method investees in the other comprehensive income.

Share-based Payments

In the case of equity-settled share-based payment, the fair value
of the goods or employee services received in exchange for the grant of the options is recognized as an expense and a capital adjustment. If the fair value of goods or employee services cannot be estimated reliably, the fair value is estimated based
on the fair value of the equity granted.

For cash-settled share-based payment, the fair value of the obligation the Company will assume
is determined by the fair value of the goods or employee services received in exchange for the grant of the options. Until the liability is settled, the Company is required to measure the fair value at date of statement of financial position and at
settlement date. The change in fair value is recognized as an expense.

Share-based payment transactions with an option for the parties
to choose between cash and equity settlement are accounted for based on the substance of the transaction.

Joint Venture

A joint venture is a contractual agreement to establish joint control over business, assets or entities. In case of jointly controlled entities that involve the establishment of a corporation, partnership or other
entity in which each participant has an interest, the Company applies the equity method of accounting. As of December 31, 2010, the Company holds 50% of ownership on Kumho Rent-A-Car Global Co., Ltd., and applies the equity method of
accounting.

Accounting Estimates

The preparation of the financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect amounts reported therein. Although these
estimates are based on managements best knowledge of current events and actions that the Company may undertake in the future, actual results may differ from those estimates.

U.S. Dollar Convenience Translation

The December 31, 2010 consolidated financial statements are expressed in Korean Won and have been translated into U.S. dollars at the rate of W1,138.9 to US$1, the market average exchange rate announced by Seoul
Money Brokerage Services, Ltd. and in effect on December 31, 2010, 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.

same way as they are recognized in the consolidated financial statements.

standards, the Companys net assets at the beginning of 2008 increased by (Won)3,852 million.

The fair value of awards granted that are expected to ultimately vest is recognized as expense over
the requisite service periods. The number of options expected to vest equals the total options granted less an estimation of the number of forfeitures expected to occur prior to vesting. The forfeiture rate is calculated based on historical data and
is adjusted if actual forfeitures differ significantly from the original estimates. The effect of any change in estimated forfeitures would be recognized through a cumulative adjustment that would be included in compensation cost in the period of
the change in estimate.

Stock Options

Other share-based compensation

The Company provided stock grants subject to both the service period and business performance goals.

The fair value of each stock grant awarded was estimated on the date of grant for performance based grants assuming that performance goals will be
achieved. The expected term for grants is generally one year. The stock grants are settled with the new shares issued or treasury stock owned by the Company upon vesting. The fair value is based on the market price of the Companys stock on the
grant date. Compensation cost is recognized over the requisite vesting period and adjusted for actual forfeitures before vesting

The
details of stocks grants as of December 31, 2010 are as follows:

23.    Retained Earnings

The Commercial Code of the Republic of Korea requires the Controlling Company to appropriate, as a legal reserve, an amount equal to a minimum of
10% of cash dividends paid until such reserve equals 50% of its issued capital stock. The reserve is not available for the payment of cash dividends, but may be transferred to capital stock with the approval of the Controlling Companys Board
of Directors or used to reduce accumulated deficit, if any, with the ratification of the Controlling Companys majority shareholders.

The Controlling Company appropriates a certain portion of retained earnings, pursuant to a shareholder resolution, as voluntary reserves. These reserves may be reversed and transferred to unappropriated retained
earnings through a resolution of shareholders, and may be distributed as dividends after the reversal.

The possibility of realization on deferred tax asset depends on many factors, such as the Companys ability,
overall economic environment, and industry prospects, within the realization period of temporary differences. The Company assesses such factors periodically, and recognizes the deferred tax assets as of December 31, 2010, as all deductable
temporary differences are considered realizable. However, the Company did not recognize the income tax assets resulting from the net operating loss carryforwards and equity-method investments to the extent the Company does not expect the related
temporary differences to be reversed within the foreseeable future.

Accounting treatment

As this was a merger between parent and subsidiary, the Controlling Company accounted for the merger using the carrying amounts
in its consolidated financial statements and accordingly, the excess of merger consideration given over the carrying amount of net assets acquired was recognized as capital adjustment after offsetting capital surplus, if any, from the similar type
of transaction.

38.    RECONCILIATION TO UNITED STATES GENERALLY ACCEPTED ACCOUNTING PRINCIPLES

The consolidated financial statements of the Company are prepared in accordance with generally accepted accounting principles in the Republic of
Korea (Korean GAAP), which differs in certain significant respects from generally accepted accounting principles in the United States of America (U.S. GAAP). Application of U.S. GAAP would have affected the
consolidated financial position of the company and subsidiaries as of December 31, 2010 and 2009 and the related consolidated net income for the three years ended December 31, 2010, 2009 and 2008 to the extent described below.

A description of the significant differences between Korean GAAP and U.S. GAAP as they relate to the Company are discussed in detail below.

(c) Companies Included in Consolidation

Under Korean GAAP, all majority-owned subsidiaries and entities of which the Company or a controlled subsidiary owns more than 30% of total
outstanding voting stock and is the largest stockholder are consolidated. However, U.S. GAAP generally requires that majority-owned subsidiaries be consolidated and that an entity in which the Company has significant influence, generally including
those in which it owns 20-50% of total outstanding voting stock, should not be consolidated; rather that entity should be accounted for under the equity method of accounting.

The following table shows the Companys percentage of ownership and carrying value of each of its affiliates that are excluded from consolidation under U.S. GAAP and instead are accounted for under the equity
method (in millions of Korean won):

(d) Debt and Equity Securities

Under Korean GAAP, non-marketable securities classified as available-for-sale securities are carried at cost or fair value if applicable with unrealized holding gains and losses reported as a capital adjustment,
net of tax. For U.S. GAAP purposes, investment in non-marketable equity securities are accounted for under the cost method or the equity method of accounting in accordance with ASC Topic 323 Investments Equity Method and Joint Ventures
and ASC Topic 325 Investments Other.

Under Korean GAAP, available-for-sale securities, whose likelihood of being disposed
within one year from the balance sheet date is probable, are classified as current. Under U.S. GAAP, when the disposition of available-for-sale securities within one year is reasonably expected, available-for-sale securities are classified as
current.

For U.S. GAAP purposes, the Company accounts for marketable equity and debt investments under the provisions of ASC Topic 320
Debt and Equity Securities. This guidance requires that marketable equity securities and all debt securities be classified in three categories and accounted for as follows:



| |  |  | Debt securities that the enterprise has the positive intent and ability to hold to maturity are classified as held-to-maturity securities and reported at
amortized cost.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | Debt and equity securities that are bought and held principally for the purpose of selling in the short term are classified as trading securities and reported at
fair value, with unrealized gains and losses included in earnings.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Debt and equity securities not classified as either held-to-maturity securities or trading securities are classified as available-for-sale securities and
reported at fair value, with unrealized gains and losses excluded from earnings and reported in a separate component of stockholders equity until realized.

The proceeds from sales of available-for-sale securities were
(Won)6,148 million in 2010,
(Won)6,833 million in 2009 and 614,405 million in 2008. The realized gains on those sales were (Won)274 million in 2010, (Won)1,716
million in 2009 and (Won)5,587 million in 2008. The average-cost method is used to calculate gains or losses from the sale of
available-for-sale securities.

Under Korean GAAP, when the subsequent recoveries of impaired available-for-sale securities and
held-to-maturity securities result in an increase of their carrying amount, the recovery gains are reported in current operations up to the previously recognized impairment loss as reversal of loss on impairment of investment securities.

Under U.S. GAAP, the subsequent increase in carrying amount of the impaired and written down held-to-maturity securities is not allowed. The
subsequent increase in fair value of available-for-sale securities is reported in other comprehensive income.

(e) Goodwill
Impairment including Investor-level Goodwill

Under Korean GAAP, goodwill, which represents the excess of the acquisition cost
over the fair value of net identifiable assets acquired, is amortized on a straight-line basis over its estimated economic useful life not exceeding 20 years. When it is no longer probable that goodwill will be recovered from expected future
economic benefits, it is expensed immediately. Also, for investments in affiliated companies accounted for using the equity method, the excess of acquisition cost of the affiliates over the Companys share of their net assets at the acquisition
date is amortized by the straight-line method over its estimated useful life.

##### Table of Contents

Under U.S. GAAP, goodwill and indefinite-lived intangible assets are not amortized, but instead are
tested for impairment at least annually. In accordance with ASC Topic 350, Intangibles-Goodwill and Other, goodwill is tested for impairment on an annual basis by comparing the fair value of the Companys reporting units to their
carrying amounts. The investor-level goodwill is tested for impairment in accordance with ASC Topic 323. The investor-level goodwill, which is recorded only at the investors financial statements, represents the excess of the acquisition cost
of equity method investees over the fair value of investors share of net identifiable assets acquired.

The changes in the
carrying amount of goodwill which is recorded in the Personal Customer Group for the years ended December 31, 2009 and 2010 are as follows (in millions of Korean won):



|                                  |  |       |         |

|Goodwill acquired during the year |  |       |        | 
|Balance as of December 31, 2010   |  | (Won) | 538,132 | 

(f) Loan Impairment

KT Capital Inc., a subsidiary of KT Corporation, estimates the allowances for the doubtful loan receivables based on the forward looking criteria (FLC), which is the regulatory guideline for assessing
the collectability of the receivables applicable to the financial institutes in Korea, as permitted under Korean GAAP.

However, under
U.S. GAAP, the impairment on the loans receivable is recorded when, based on current information and events, it is probable that a creditor will be unable to collect all amounts due according to the contractual terms of the loan agreement.

(g) Additional Equity Investments in and Transactions of Subsidiaries

Under Korean GAAP, subsequent to acquiring a controlling financial interest in a subsidiary, additional equity investments by the Company in a
subsidiaries stock and other equity transactions of subsidiaries are accounted for assuming such transactions occur as of the date of audited or reviewed financial statements of the acquired subsidiary closest to the date of acquisition. In
addition, the difference between the Companys cost of the acquired additional interest and the corresponding share of stockholders equity of the acquired subsidiary is presented as an adjustment to capital surplus.

Under U.S. GAAP, such equity investments in and transactions of affiliates and subsidiaries are recorded and accounted for as of the date the
transaction occurs. As a result, the Company has a different basis in its equity investments in the subsidiaries under Korean GAAP as compared to U.S. GAAP. Therefore, any gains or losses recorded by the Company (which are recorded as capital
transactions in stockholders equity) when an equity investee sells shares of its stock will be different under U.S. GAAP as compared to Korean GAAP. In addition, prior to the fiscal year beginning on or after December 15, 2008, under U.S.
GAAP, the cost of an additional equity interest would be allocated based on the fair value of net tangible and identifiable assets acquired and liabilities assumed, with the excess allocated to goodwill.

(h) Intangible Assets

Under Korean GAAP, the frequency usage right related to the second generation (2G) paid by the initial stockholders to obtain the
operating licenses prior to the establishment of KTM.Com Co., Ltd. (KTM), which was merged into KTF in 2001, was not recognized as an intangible asset in applying purchase accounting of KTM by KT in 2000.

##### Table of Contents

Under U.S. GAAP, the 2G frequency usage right was considered as indefinite lived intangible asset and
thus in the process of purchase accounting of KTM, KT recognized the frequency usage right at fair value. However, on December 31, 2005, the Korea Communication Act (Act) was revised effective July 1, 2006. Under the revised
Act, the frequency usage right of 2G will expire by June 2011. Thus, the Company amortizes the frequency usage right of 2G over the remaining useful life under U.S. GAAP beginning from the year ended December 31, 2006.

In addition, the frequency usage right related to the third generation (3G) acquired in 2000 has been accounted for in the same manner
under Korean GAAP and U.S. GAAP.

Identifiable intangible assets determined in accordance with U.S. GAAP as of December 31, 2010
and 2009 are presented below.

The weighted-average amortization period of total amortized intangible assets, internal-use software, frequency
usage rights and utilization rights are 9 years, 6 years, 11 years and 20 years, respectively. The Company has no identifiable intangible assets that are not subject to amortization.

(i) Depreciation

In
1995, KT adopted a method of depreciation, as allowed under Korean GAAP, whereby property and equipment placed in service at any time during the first half of the year received a full year of depreciation expense, and property and equipment placed
in service at any time during the



F-81

##### Table of Contents

second half of the year received one-half year of depreciation. Also, as permitted under Korean GAAP, depreciation of these assets was based on lives which are shorter than their economic useful
lives. In 1996, KT adopted the policy, also acceptable under Korean GAAP, whereby property and equipment is depreciated from the actual date it is placed in service, while continuing to use useful lives which are shorter than the economic useful
lives of such assets. In 1998, under Korean GAAP, as required under a ruling by the National Tax Service (which is also applicable under Korean GAAP), the Company changed the estimated useful lives of certain assets, including underground access to
cable tunnels and concrete and steel telephone poles acquired after 1995, from 6 years to periods ranging from 20 years to 40 years, and changed the depreciation method from the declining-balance method to the straight-line method.

In 1999, under Korean GAAP, the Company changed its depreciation method for buildings and structures acquired before December 31, 1994, from
the declining-balance method to the straight-line method in order to be consistent with the method applied to buildings and structures acquired after January 1, 1995.

Under U.S. GAAP, property and equipment is generally depreciated over its estimated useful life in a systematic and rational manner. In addition, the depreciation method in the year of acquisition based on the
Companys in-service dates for its capital additions in 1995 described above, does not comply with U.S. GAAP in that significant depreciation expense is recognized prior to the actual use of the asset. The change in estimated useful lives in
1998, and the changes in 1998 and 1999 from the declining-balance method to the straight-line method would also not be appropriate under U.S. GAAP. Accordingly, adjustments have been reflected for U.S. GAAP purposes for the effect of each of these
items.

Under U.S. GAAP, property and equipment is depreciated by using the declining-balance method except for the assets of certain
subsidiaries, buildings and structures acquired in 1995 and thereafter which are depreciated using the straight-line method.

Under U.S.
GAAP, the useful lives of property and equipment are summarized as follows:



|                                                                            |  |                        |             |

|Tools, furniture and fixtures:                                              |  |                        |             | 
|Steel safe boxes                                                            |  |                        | 20 years    |

(j) Interest Capitalization

Under Korean GAAP, prior to January 1, 2003, interest was capitalized on borrowings related to the construction of all property and equipment and IMT-2000 frequency usage right, incurred prior to completing
the acquisition, as part of the cost of such assets. Effective January 1, 2003, Korean GAAP was revised to allow a company to charge such interest expense to current operations. For Korean GAAP purpose, the Company adopted in 2003 the
accounting policy not to capitalize such financing costs prospectively.

Under U.S. GAAP, interest costs related to certain assets that
are routinely manufactured or otherwise produced in large quantities on a regular basis are not in the scope of interest capitalization. In addition, interest is capitalized in the amount that would have theoretically been avoided had expenditures
not been made for assets which require a period of time to get them ready for their intended use.

Under U.S. GAAP, details of interest capitalization for the years ended December 31, 2010, 2009
and 2008 are as follows (in millions of Korean won):

(k) Revenue Recognition

Under Korean GAAP, non-refundable service installation fees for telephone and initial subscription fees for PCS and leased-line services are recognized as revenue when installation and initiation services are
rendered.

Under U.S. GAAP, 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. In 2009, due to a change in the market condition the Company changed the estimate of the expected terms of customer relationships of telephone, PCS, and leased-line service
from 15 years to 11 years, from 4 years to 2 years and from 3 years to 6 years, respectively. The change in the estimated expected terms of customer relationships is accounted for as a change in accounting estimate on a prospective basis effective
January 1, 2009 under the accounting standard related to change in accounting estimates. As a result, net income for the year ended December 31, 2009 increased by (Won)153 billion.

Under Korean GAAP, handset subsidy paid by the Company is accounted for as
expenses. However, under U.S. GAAP, the handset subsidy is treated as reduction of revenue in accordance with ASC Topic 605, Revenue Recognition.

Under Korean GAAP, the sales of the certain real estate are accounted for as the revenue and the costs of the related real estate are recorded as the cost of sales under certain circumstances permitted under Korean
GAAP. However, under U.S. GAAP, gains and losses from the sale of the property used for operation are required to be recorded as a component of operating income in net of the proceeds from the sale and the related costs.

(l) Income Taxes

Under Korean GAAP, recognition of deferred income tax benefit from equity in losses of affiliates requires realization of the benefit within the
near future, which is interpreted to mean within 5 years. The Company does not believe it is probable to realize such benefit within 5 years.

Under U.S. GAAP, deferred income tax assets are recognized for an excess of the tax basis over the amount for financial reporting of domestic and foreign investments accounted for on the equity method (except for
corporate joint ventures). However, deferred income tax assets related to consolidated subsidiaries are recognized only if it is apparent that the temporary difference will reverse in the foreseeable future.

Under Korean GAAP, in accordance with SKAS No. 16, effective from January 1, 2005, the Company did not recognize deferred income tax
liabilities related to equity in gains of affiliates when it is able to control the timing of the reversal of the temporary difference and it is probable that the temporary difference will not reverse in the foreseeable future.

Under U.S. GAAP, deferred income tax liabilities are fully recognized for an excess of the amount for financial reporting over the tax basis of an
investment in domestic subsidiaries and corporate joint ventures, unless the investment in the subsidiary can be recovered tax-free under local



F-83

##### Table of Contents

tax laws and management expects that it will ultimately use that means. However, deferred income tax liabilities are not recognized in an investment in a more than 50 percent-owned foreign
subsidiary or foreign corporate joint venture that is essentially permanent in duration.

Under U.S. GAAP, on January 1, 2007, the
Company adopted accounting guidance which clarifies the accounting guidance for uncertainties in income taxes. The guidance requires that the tax effect(s) of a position be recognized only if it is more-likely-than-not to be sustained
based solely on its technical merits as of the reporting date. The more-likely-than-not threshold represents a positive assertion by management that a company is entitled to the economic benefits of a tax position. If a tax position is not
considered more-likely-than-not to be sustained based solely on its technical merits, no benefits of the tax position are to be recognized. The more-likely-than-not threshold must continue to be met in each reporting period to support continued
recognition of a benefit. With the adoption of the accounting guidance, companies are required to adjust their financial statements to reflect only those tax positions that are more-likely-than-not to be sustained.

(m) Foreign Currency Transactions

Under Korean GAAP, prior to January 1, 2003, all unrealized foreign currency translation gains and losses on monetary assets and liabilities, except for amounts included in the cost of property and equipment,
were included in the results of operations. Effective January 1, 2003 the Company adopted SKAS No. 7, Capitalization of Financing Costs. As allowed by the standard, the Company elected to include all unrealized foreign currency
translation gains and losses (including property and equipment) in the results of operations.

Under U.S. GAAP, all foreign exchange
transaction gains and losses (referred to as translation gains and losses under Korean GAAP) are included in the results of operations for the current period and therefore, the amounts included in property and equipment and related depreciation
expense under Korean GAAP are reversed.

Under Korean GAAP, the convertible notes denominated in a foreign currency are regarded as
non-monetary liabilities since they have equity-like characteristics, and the Company does not recognize the associated foreign currency translation gain and loss.

Under U.S. GAAP, the convertible notes denominated in a foreign currency are translated at the rate of exchange on the balance sheet date, and the resulting foreign currency transaction gain and loss is included in
the results of operations.

(n) Noncontrolling Interest

Under Korean GAAP, minority interest in consolidated subsidiaries, which is noncontrolling interest under US GAAP, is presented as a separate
component of equity in the consolidated balance sheet.

Under U.S. GAAP, as described in Note 38 (r) in 2009 the Company
retrospectively adopted the presentation and disclosure provisions of new accounting guidance on a noncontrolling interest in its consolidated financial statements, which required noncontrolling interest to be presented as a separate component of
equity in the consolidated financial statements as well as modified the presentation of net income and other comprehensive income to be attributed to controlling and noncontrolling interest. Consequently, there is no GAAP difference any longer in
terms of presentation of noncontrolling interest in the consolidated financial statements except for terminology.

(o) Other

Korean GAAP requires gains and losses from the sale of property and equipment, impairment write-downs and other bad debt expenses to be included as part of non-operating income (expense). Under U.S. GAAP, gains and
losses from the sale of property and equipment, impairment write-downs and other bad debt expenses are required to be recorded as a component of operating income.

Under Korean GAAP, purchase of treasury stock is regarded as temporary and does not impact the ownership percentages of stockholders unless there is an explicit purpose of retirement of the repurchased shares in
accordance with resolution of board of directors or stockholders meeting. Under U.S. GAAP, purchase of treasury stock results in a change of an entitys ownership structure and ownership percentages of stockholders.

(p) Comprehensive Income

Prior to January 1, 2007, Korean GAAP did not require the presentation of comprehensive income, however, effective January 1, 2007, the Company adopted SKAS No. 21, Preparation and Presentation
of Financial Statements 1, which requires separate disclosure of the details of comprehensive income. Consequently, there is no GAAP difference any longer in terms of disclosure of comprehensive income and its components.

Corporation), KTR Co., Ltd, KT Rental, KT-LIG ACE Private Equity Fund, Vanguard Private Equity Fund and Doremi Media, which are accounted for under the equity method under U.S. GAAP.

is categorized as investing activities net of cash paid or received.

(r) Significant Recent Accounting Pronouncements



|(i) | In June 2009, the FASB amended the consolidation rules related to Variable Interest Entities (VIEs). The new rules expand the primary beneficiary analysis to
incorporate a qualitative review of which entity controls and directs the activities of the VIE. The amendments also modify the rules regarding the frequency of ongoing reassessments of whether a company is the primary beneficiary. Under the revised
guidance, companies are required to perform ongoing reassessments as opposed to only when certain triggering events occur, as was previously required. This guidance is effective in 2010 and there is no material impact on the consolidated financial
statements.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(ii) | In October 2009, the FASB issued ASU 2009-13 Multiple-Deliverable Revenue Arrangements. The update addresses how revenues should be allocated among all products and
services included in sales arrangements. It establishes a selling price hierarchy for determining the selling price of each product or service, with vendor-specific objective evidence (VSOE) at the highest level, third-party evidence of
selling price at the intermediate level, and a best estimate of the selling price at the lowest level. It replaces fair value with selling price in revenue allocation guidance, eliminates the residual method as an acceptable
allocation method, and requires the use of the relative selling price method as the basis for allocation. It also significantly expands the disclosure requirements for such arrangements, including, potentially, certain qualitative disclosures. ASU
2009-13 will be effective prospectively for sales entered into or materially modified in fiscal years beginning on or after June 15, 2010. The FASB permits early adoption of ASU 2009-13, applied retrospectively, to the beginning of the year of
adoption. The Company has not early adopted the accounting standard in 2010.
|---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(iii) | In October 2009, the FASB issued ASU 2009-14 Certain Revenue Arrangements That Include Software Elements. The update clarifies the guidance for allocating and
measuring revenue, including how to identify software that is out of the scope. The update also amends accounting and reporting guidance for revenue arrangements involving both tangible products and software that is more than incidental to the
tangible product as a whole. That type of software and hardware will be outside of the scope of software revenue guidance, and the hardware components will also be outside of the scope of software revenue guidance and may result in more
revenue recognized at the time of the hardware sale. Additional disclosures will discuss allocation of revenue to products and services in sales arrangements and the significant judgments applied in the revenue allocation method, including impacts
on the timing and amount of revenue recognition. ASU 2009-14 will be effective prospectively for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. ASU 2009-14 has the same effective
date, including early adoption provisions, as ASU 2009-13. The Company has not early adopted the accounting standard in 2010.

|(iv) | In December 2009, the FASB issued ASU 2009-16 Transfers and Servicing. This update removes the concept of a qualifying special-purpose entity (QSPE) and
creates more stringent conditions for reporting a transfer of a portion of a financial asset as a sale. To determine if a transfer is to be accounted for as a sale, the transferor must assess whether it and all of the entities included in its
consolidated financial statements have surrendered control of the assets. This standard is effective from January 1, 2010, with adoption applied prospectively for transfers that occur on and after the effective date. The elimination of the QSPE
concept requires to retrospectively assess all current off-balance sheet QSPE structures for consolidation under ASC Topic 810, Consolidation, and record a cumulative-effect adjustment to retained earnings for any consolidation change.
Retrospective application of ASU 2009-16, specially the QSPE removal, is being assessed as part of the analysis required from ASU 2009-17, Improvements to Financial Reporting by Enterprises Involved with Variable Interest Entities. Refer
to the section below for further information related to ASU 2009-17.

|(v) | In January 2010, the FASB amended the disclosure guidance related to fair value measurements. The amended disclosure guidance requires new fair value measurement disclosures and
clarifies existing fair value measurement disclosure requirements. The amended disclosure guidance related to disclosures about purchases, sales, issuances and settlements of Level 3 instruments will be effective for fiscal years beginning after
December 15, 2010. The remaining amended disclosure guidance will be effective for annual reporting periods beginning after December 15, 2009. The Company adopted the guidance in 2010 with no material impact on the consolidated financial
statements.

|(vi) | In January 2010, the FASB issued authoritative guidance for improving disclosures about fair value measurements, which requires new and amended disclosure requirements for
classes of assets and liabilities, inputs and valuation techniques and transfers between levels of fair value measurements and accounting for distributions to shareholders with components of stock and cash, which clarifies the accounting for
distributions to shareholders that offer them the ability to elect to receive their entire distribution in cash or shares of equivalent value. The Company adopted the guidance in 2010 with no material impact on the consolidated financial statements.
|---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(vii) | The FASB issued ASU 2010-09 on February 24, 2010 to amend ASC 855,Subsequent Events to address certain implementation issues. The amendments remove the requirement for an
SEC filer to disclose a date in both issued and revised financial statements. Revised financial statements include financial statements revised as a result of either correction of an error or retrospective application of U.S. GAAP. Additionally, it
has clarified that if the financial statements have been revised, then an entity that is not an SEC filer should disclose both the date that the financial statements were issued or available to be issued and the date the revised financial statements
were issued or available to be issued. That amendment is effective for interim or annual periods ending after June 15, 2010. The Company adopted the standard in 2010 with no material impact on the consolidated financial statements.
|----- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(viii) | The FASB issued ASU 2010-20 on July 21, 2010 to provide financial statement users with greater transparency about an entitys allowance for credit losses and the credit
quality of its financing receivables. This amendment is intended to provide additional information to assist financial statement users in assessing and entitys credit risk exposures and evaluating the adequacy of its allowance for credit
losses. The disclosures as of the end of a reporting period are effective for interim and annual reporting periods ending on or after December 15, 2010. The disclosures about activity that occurs during a reporting period are effective for
interim and annual reporting periods beginning on or after December 15, 2010. The Company adopted the standard in 2010 and accordingly, disclosed the additional information related to credit risk.

Basic income per share is computed on the basis of the weighted-average number of common stock outstanding. Diluted
income per share is computed on the basis of the weighted-average number of common stock outstanding plus the effect of outstanding exchangeable bonds, stock option and other stock compensation using the if-exchanged method and the
treasury stock method if dilutive. The denominator of the diluted income per share computation is adjusted to include the number of additional common stock that would have been outstanding had the dilutive potential common stock been
issued at the beginning of the period or since issued. In addition, the numerator is adjusted to include the after-tax amount of interest and foreign currency translation gain (loss) recognized associated with the exchangeable bonds. 43,153 shares,
365,832 shares and 417,785 shares of stock options outstanding as of December 31, 2010, 2009 and 2008, respectively, were not considered when calculating dilutive income per share because the exercise price of the stock options was greater than
the average market price of the shares and, therefore the effect would have been antidilutive.

The effective tax rates after adjustments of certain differences between amounts reported for financial accounting
and income tax purpose, were approximately 23.8%,12.3% and 23.6% for the years ended December 31, 2010, 2009 and 2008, respectively.

The tax effects of temporary differences that resulted in significant portions of the deferred income tax assets and liabilities at
December 31, 2010 and 2009, computed under U.S. GAAP, and a description of financial statement items that created these differences are as follows (in millions of Korean won):

In 2010 and 2009, valuation allowances were recognized by certain subsidiaries as realization of
deferred income tax asset was not assessed as more likely than not mainly due to lack of expected future taxable income.

In 2010, the
Company was eligible for tax credits of (Won)257,331 million. However, due to the minimum tax provisions, the Company utilized only (Won)150,720 million. The remaining tax credit will expire in 2015. During 2010, the Company concluded that the remaining tax credits was more likely
than not of realization in the future based on future taxable income estimates. As a result, the Company recorded an income tax benefit of
(Won)88,794 million of the tax credit. The tax loss carryforwards of (Won)266,147 million as of December 31, 2010 will expire through 2020. During 2010, certain subsidiaries including KT Tech did not recognize deferred income tax assets amounting to (Won)57,620 million which resulted from the tax effects of tax loss carryforwards of (Won)261,909 million in excess of taxable differences and future taxable income. The valuation allowances reflect the uncertainty surrounding the Companys ability to generate sufficient future taxable
income in certain tax jurisdictions to utilize its net operating losses and the Companys ability to generate sufficient capital gains to utilize all capital losses.

In assessing the realizability of deferred income tax assets, management considers whether it is more likely than not that some portion or all of the deferred income tax assets will not be realized. The ultimate
realization of deferred income tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible and tax carryforwards are utilizable. Management considers the scheduled
reversal of deferred income tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. Based upon the level of historical taxable income and projections for future taxable income over the periods in
which the deferred income tax assets are deductible or utilized, management believes it is more likely than not that the Company will realize the benefits of these deductible differences, net of the valuation allowance recorded at December 31,
2010 and 2009. The amount of the deferred income tax asset considered realizable, however, could be reduced in the near term if estimates of future taxable income are reduced.

The amount of unrecognized tax benefits that would favorably affect the effective income tax rate was
(Won)5,761 million and
((Won)25,872) million for the years ended December 31, 2010 and 2009, respectively. The liability for uncertain tax positions is
classified as a non-current liability in accordance with the guidance.

A reconciliation of the total amounts of unrecognized tax
benefits at the beginning and end of the period is as follows (in millions of Korean won):

The Companys practice is to classify interest on uncertain tax positions in non-operating expense whereas
penalties are classified in income tax expense. The Company recognized (Won)605 million and (Won)347 million in penalties for the years ended December 31, 2010 and 2009, respectively. As of December 31, 2010 and 2009, the Company
had (Won)1,514 million and
(Won)909 million accrued for the payment of penalties.

The Company has open tax years ranging from 2006 to 2010, by which its taxes remain subject to
examination. However, the Company does not anticipate that the total amount of unrecognized tax benefits will significantly change in the next 12 months.

(b) Fair Value Measurements

Fair value is defined as the price that would be received
to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (an exit price). GAAP establishes a valuation hierarchy for prioritizing the inputs and the hierarchy places greater
emphasis on the use of observable market inputs and less emphasis on unobservable inputs. When determining fair value, an entity is required to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of
the hierarchy are as follows: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3,
defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

Following is a description of the valuation methodologies the Company used for instruments measured at fair value, as well as the general
classification of such instruments pursuant to the valuation hierarchy.

(i) Recurring Fair Value

Securities

The Company
classifies its securities within Level 1 of the valuation hierarchy where quoted prices are available in an active market.

Derivatives

The Company
generally classifies derivatives within Level 2 of the valuation hierarchy. The derivative financial instruments consist of cross currency interest rate swap and forward. The cross currency interest swaps and forward are valued using valuation
models that use as their basis readily observable market inputs, such as time value, forward interest rates, volatility factors and current and forward market prices for foreign currency.

(ii) Non-recurring Fair Value

In 2009, the Company adopted the provisions of the authoritative guidance on fair value measurements for nonfinancial assets and nonfinancial liabilities that the Company does not recognize or disclose at fair
value on a recurring basis (at least annually). These include reporting units measured at fair value in a goodwill impairment test, other nonfinancial assets or liabilities measured at fair value for impairment testing, and nonfinancial assets
acquired and liabilities assumed in a business combination. In connection with the adoption of this guidance the Company analyzed and evaluated

them to determine whether nonfinancial assets and liabilities had any evidences of impairment. As a result of the evaluation, the Company noted that it currently does not have significant
non-financial assets or non-financial liabilities that are required to be measured at fair value on a non-recurring basis.

(c)
Fair Value of Financial Instruments

The following method and assumptions were used to estimate the fair value of each
significant class of financial instrument for which it was practicable to estimate such value:

(i) Cash and cash equivalents,
short-term financial instruments, accounts receivable, accounts payable and short-term borrowings

The carrying amount approximates
fair value due to the short-term maturity of these instruments and credit risk.

(ii) Loans to employees

The carrying amount of short-term loans approximates fair value due to the short term maturities of these loans. The fair value of long-term loans
is estimated based on discounted cash flows using current rates offered for loans of the similar remaining maturities.

(iii)
Long-term debt

The fair value of the long-term debt, including current portion, is estimated based on quoted market prices for the
same or similar issues or on the current rates offered for debt of the same remaining maturities.

The estimated fair values of the
Companys significant financial instruments at December 31, 2010 and 2009 are summarized as follows (in millions of Korean won):

The maximum exposure to credit risk of each class of receivables is equal to the book value of each class of
receivable as of December 31, 2010.

Credit risk is managed at the company level to minimize the financial loss. Credit risk arises
in the ordinary course of transactions and investing activities, where clients or other party fails to discharge an obligation. The Company considers the counterpartys credit on a periodic basis 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, the Company transacts only with financial institutions which have strong credit rating.
