Competition may reduce our market share and harm our results of operations and financial condition.

 

We face substantial competition in the wireless telecommunications sector in Korea. We expect competition to intensify as a result of consolidation of market leaders and the development of new technologies, products and services. We expect that such trends will continue to put downward pressure on the prevailing tariffs we can charge our subscribers. Also, continued competition from the other wireless and fixed-line service providers has resulted in, and may continue to result in, a substantial level of deactivations among our subscribers. Subscriber deactivations, or churn, may significantly harm our business and results of operations. For 2007, our churn rate ranged from 2.0% to 3.2%, with an average churn rate of 2.6%, compared to an average churn rate of 2.0% for 2006. We cannot assure you that our churn rates will not increase in the future. In addition, increased competition may cause our marketing expenses to increase as a percentage of sales, reflecting higher advertising expenses and other costs of new marketing activities, which may need to be introduced to attract and retain subscribers.

 

Prior to April 1996, we were the only wireless telecommunications service provider in Korea. Since then, several new providers have entered the market, offering wireless voice and data services that compete directly with our own. Together, these providers had a market share of approximately 49.5%, in terms of numbers of wireless service subscribers, as of December 31, 2007. Furthermore, in 2001, the Government awarded three companies the licenses to provide high-speed third generation, or 3G, wireless telecommunications services. In Korea, this 3G license is also known as the “IMT-2000” license. IMT-2000 is the global standard for 3G wireless communications, as defined by the International Telecommunication Union, an organization established to standardize and regulate international radio and telecommunications. One of these licenses was awarded to our former subsidiary, SK IMT Co., Ltd., which was merged into us on May 1, 2003, and the other two licenses were awarded to consortia led by or associated with KT Corporation, Korea’s principal fixed-line operator and the parent of KTF, one of our principal wireless competitors, and to LG Telecom, Ltd., or LGT. In addition, our wireless voice businesses compete with Korea’s fixed-line operators, and our wireless Internet businesses compete with providers of fixed-line data and Internet services.

 

Since 2000, there has been considerable consolidation in the wireless telecommunications industry, resulting in the emergence of stronger competitors. In 2000, KT Corporation acquired a 47.9% interest in Hansol M.Com (formerly Hansol PCS Co., Ltd.), which was then the fifth largest wireless operator in terms of numbers of wireless service subscribers. Hansol M.Com subsequently changed its name to KT M.Com and merged into KTF in May 2001. In May 2002, the Government sold its remaining 28.4% stake in KT Corporation. KT Corporation had a 53.0% interest in KTF as of December 31, 2007. Such consolidation has created large, well-capitalized competitors with substantial financial, technical, marketing and other resources to respond to our business offerings. Future business combinations and alliances in the telecommunications industry may also create significant new competitors and could harm our business and results of operations.

 

In addition, in March 2006 the MIC partially lifted, and in March 2008 the KCC fully lifted, the prohibition on the provision of handset subsidies, which had been in place since June 2000. See “— Our businesses are subject to extensive Government regulation and any change in Government policy relating to the telecommunications industry could have a material adverse effect on our results of operations and financial condition”. This recent decision by the MIC has intensified competition among mobile service providers and may increase our marketing expenses relating to the provision of handset subsidies, which could, in turn, adversely affect our results of operations.

Furthermore, in 2007, the MIC announced a “road map” highlighting revisions in regulations to promote deregulation of the telecommunications industry. In accordance with the road map and pursuant to the Combined Sales Regulation, promulgated in May 2007, telecommunications service providers are now permitted to bundle their services, such as wireless data service, wireless voice service, broadband Internet access service and fixed-line telephone service, at a discounted rate; provided, however, that we and KT Corporation, which are designated as market-dominating business entities under the Telecommunications Business Act, allow other competitors to employ the services provided by us and KT Corporation, respectively, so that such competitors can provide similar discounted package services. The road map also includes plans to amend the regulations and provisions under the Telecommunications Business Act to permit licensed transmission service providers to offer local, domestic long-distance and international telephone services, as well as broadband Internet access and Internet phone services, without additional business licenses. The proposed amendment is currently being considered by the KCC. The introduction of bundled services may further increase competition in the telecommunications sector, as well as cause downward price pressure on the fees we charge for our services, which, in turn, may have a material adverse effect on our results of operations, financial position and cash flows.

 

We expect competition to intensify as a result of such consolidation, regulatory changes and as a result of the rapid development of new technologies, products and services. Our ability to compete successfully will depend on our ability to anticipate and respond to various competitive factors affecting the industry, including new services that may be introduced, changes in consumer preferences, economic conditions and discount pricing strategies by competitors.

 

Inability to successfully implement or adapt our network and technology to meet the continuing technological advancements affecting the wireless industry will likely have a material adverse effect on our financial condition, results of operation, cash flows and business.

 

The telecommunications industry has been characterized by continuous improvement and advances in technology and this trend is expected to continue. For example, we and our competitors have implemented technology upgrades from basic code division multiple access, or CDMA, networks to more advanced high-speed wireless telecommunications networks based on CDMA 1xRTT and CDMA 1xEV-DO technology. Korean wireless telecommunications companies, including us, have also implemented newer technologies such as wide-band code division multiple access, or WCDMA, which is the 3G technology implemented by us. In 2005, we began to upgrade our WCDMA network to support high-speed downlink packet access, or HSDPA, technology. HSDPA, which represents an evolution of the WCDMA standard, is a more advanced 3G technology than the initial WCDMA technology we implemented and is sometimes referred to as “3.5G” technology. Our HSDPA-capable WCDMA network, which was completed in March 2007, supports data transmission services at significantly higher data transmission speeds than our basic CDMA, CDMA 1xRTT and CDMA 1xEV-DO networks. We are currently further upgrading our WCDMA network to support even more advanced high-speed uplink packet access, or HSUPA, technology. The more successful operation of a 3G network by a competitor, including better market acceptance of a competitor’s 3G-based services, could materially and adversely affect our existing wireless businesses as well as the returns on future investments we may make in our 3G network or our other businesses.

 

In addition, in March 2005, we also obtained a license from the MIC to provide wireless broadband internet, or WiBro, services. WiBro enables us to offer high-speed and large-packet data services, including wireless broadband Internet access to portable computers and other portable devices, but does not support voice transmission. We commercially launched WiBro service in June 2006, initially to 24 “hot zone” areas, which are neighborhoods and districts that we have determined to be high-data traffic areas, in seven cities in Korea. By the end of 2007, we had extended WiBro service to “hot zone” areas in 23 cities throughout Korea. In 2008, we plan to expand WiBro service to hot zone areas in 42 cities. Beyond 2008, our WiBro expansion plans will depend, in part, on subscriber demand for WiBro services. As the implementation of WiBro service in Korea is relatively new, we cannot assure you that there will be sufficient demand for our WiBro services. Our WiBro services may not be commercially successful if market conditions are unfavorable or service demand is weak.

 

For a more detailed description of our backbone networks, see “Item 4.B. Business Overview — Digital Cellular Network”.

Our business could also be harmed if we fail to implement, or adapt to, future technological advancements in the telecommunications sector in a timely manner.

 

Implementation of 3G and WiBro technologies has required, and may continue to require, significant capital and other expenditures, which we may not recoup.

 

We have invested significant capital and resources to develop and implement our 3G technologies, including investments related to the commercial development of WCDMA technology and the build-out of our WCDMA network. We completed nationwide expansion of our WCDMA network, which is fully HSDPA-capable, in the first quarter of 2007. In 2007, our capital expenditures related to expansion of our WCDMA network amounted to Won 1,044.3 billion. We also expect to devote additional capital resources in 2008 to enhance our 3G service quality and increase our WCDMA network capacity, including through the installation of additional small cell sites and cellular repeaters to improve reception quality in subterranean areas, buildings or any remaining “blind spots” where reception quality may not be optimal, as well as the implementation of HSUPA upgrades to our WCDMA network. We expect our WCDMA network to be fully HSUPA-capable by the end of 2009. HSUPA technology represents yet the next stage in the evolution of the WCDMA standard. The HSUPA upgrades may be accomplished through relatively simple channel card replacements at relatively low cost. For a more detailed description of our backbone networks, see “Item 4.B. Business Overview — Digital Cellular Network”.

 

We cannot assure you that demand for our 3G services will be sufficient to recoup our aggregate capital expenditures in developing and implementing our 3G technologies, including costs related to the procurement of our IMT-2000 license and construction our WCDMA network. Also, we cannot assure you that there will be sufficient demand for our 3G services, as a result of competition or otherwise, to permit us to recoup or profit from our investment.

 

We have also made, and intend to continue to make, capital investments to develop and launch our WiBro services. In addition to the initial Won 117.0 billion WiBro license fee we paid to the MIC in March 2005, we spent Won 153.6 billion in capital expenditures in 2007 to build and expand our WiBro network. We plan to spend additional amounts to expand our WiBro network in 2008, and may make further capital investments related to our WiBro service in the future. Our WiBro-related investment plans are subject to change, and will depend, in part, on market demand for WiBro services, the competitive landscape for provision of such services and the development of competing technologies. We cannot assure you that there will be sufficient demand for our WiBro services, as a result of competition or otherwise, to permit us to recoup or profit from our WiBro-related capital investments. KT Corporation commercial launched its WiBro service in 2006. The more successful operation of a WiBro network by KT Corporation, or another competitor, including better market acceptance of a competitor’s WiBro services, could also materially and adversely affect our business.

 

Our growth strategy calls for significant investments in new businesses and regions, including businesses and regions in which we have limited experience.

 

As a part of our growth strategy, we plan to selectively seek business opportunities abroad. In February 2005, we established a joint venture company, UNISK Information Technology Co., Ltd., with China Unicom Ltd., China’s second largest mobile operator, to market and offer wireless data service in China. In July 2006, we also acquired US$1 billion in aggregate principal amount of China Unicom’s convertible bonds, which, in August 2007, we converted into a 6.6% equity interest in China Unicom. In May 2008, China Unicom announced that it may merge with China NetCom, a leading broadband communications and fixed-line telecommunications operator in China. In the event the merger is consummated, we expect our equity interest in China Unicom to decrease to 3.8% from 6.6%. We also have ongoing projects in Vietnam. In addition, in May 2006 our subsidiary, HELIO, launched cellular voice and data services across the United States. In June 2008, we and EarthLink, our joint venture partner in HELIO, entered into an agreement with Virgin Mobile USA, Inc. and certain of its affiliates, pursuant to which Virgin Mobile USA, Inc. and certain of its affiliates agreed to acquire our aggregate equity interest in HELIO in exchange for limited partnership units in Virgin Mobile USA, L.P. (Virgin Mobile USA, Inc.’s operating company), subject to regulatory approvals. In June 2008, we also agreed to invest US$25 million to acquire mandatory convertible preferred stock, convertible into common stock of Virgin Mobile USA, Inc. See “Item 4.B. Business Overview — Our Business Strategy — Global Business — United States” for more information regarding our

investments in HELIO and Virgin Mobile USA, Inc. These global businesses may require further investment from us. We continue to seek other opportunities to expand our business abroad, particularly in Asia and the United States, as such opportunities present themselves. For a more detailed description of our investments in our global business, see “Item 4.B. Business Overview — Our Services — Global Business”.

 

We have also pursued convergence growth opportunities. For example, in March 2008, we completed the acquisition of an additional equity stake in hanarotelecom, Korea’s second-largest fixed-line operator, for approximately Won 1.1 trillion and currently hold a 43.4% equity stake in the company. While we are hoping to benefit from a range of synergies from this acquisition, including by offering our customers bundled fixed-line and mobile telecommunications services, we may not be able to realize those expected benefits in the near term, or at all. In particular, we may experience difficulties in integrating hanarotelecom’s fixed-line telecommunications and broadband Internet services with our existing products and services and we may be unsuccessful in retaining hanarotelecom’s existing customers. In addition, in April and May 2008, more than 3,000 customers filed a lawsuit against hanarotelecom with the Seoul Central District court alleging that hanarotelecom had violated customers’ privacy, and an investigation against hanarotelecom was initiated by the Seoul Central Prosecutor’s Office, the KCC and the Korea Trade Commission. In connection with this investigation, on June 24, 2008, the KCC suspended hanarotelecom from soliciting new subscribers to its broadband Internet services for a period of 40 days and, in addition, imposed an administrative fine of Won 180 million on the grounds that hanarotelecom had violated the Telecommunication Business Act and standard customer contracts. hanarotelecom has the right to file an administrative appeal within 90 days of this ruling. For more information regarding this lawsuit, see “Item 8.A. Consolidated Statements and Other Financial Information — Legal Proceedings — Hanarotelecom Litigation”.

 

We believe that we must continue to make significant investments to build, develop and broaden our existing businesses, including by developing and improving our wireless data, multimedia, mobile commerce and Internet services. We will need to respond to market and technological changes and the development of services which we may have little or no experience in providing. Entering into these new businesses and regions in which we have limited experience may require us to make substantial investments and, in spite of such investments, we may still be unsuccessful in these efforts to expand and diversify. In addition, when we enter into these businesses and regions with partners through joint ventures or other strategic alliances, we and those partners may have disagreements with respect to strategic directions or other aspects of business, or may otherwise be unable to coordinate or cooperate with each other, any of which could materially and adversely affect our operations in such businesses and regions.

 

Due to the existing high penetration rate of wireless services in Korea, we are unlikely to maintain our subscriber growth rate, which could adversely affect our results of operations.

 

According to data published by the MIC and our population estimates based on historical data published by the National Statistical Office of Korea, the penetration rate for the Korean wireless telecommunications service industry as of December 31, 2007 was approximately 89.8%, which is high compared to many industrialized countries. Therefore, it is unlikely that the penetration rates for wireless telecommunications service in Korea will grow significantly. As a result of the already high penetration rates in Korea for wireless services coupled with our large market share, we expect our subscriber growth rate to decrease. Slowed growth in penetration rates without a commensurate increase in revenues through the introduction of new services and increased use of our services by existing subscribers would likely have a material adverse effect on our financial condition, results of operations and cash flows.

 

Our business and results of operations may be adversely affected if we fail to acquire adequate additional spectrum or use our bandwidth efficiently to accommodate subscriber growth and subscriber usage.

 

One of the principal limitations on a wireless network’s subscriber capacity is the amount of spectrum available for use by the system. We have been allocated 2 x 22.5 MHz of spectrum in the 800 MHz band. As a result of bandwidth constraints, our CDMA 1xRTT network is currently operating near its capacity in the Seoul metropolitan area, although capacity constraints are not as severe for transmissions utilizing CDMA 1xEV-DO technology. While we believe that we can address this issue through system upgrades and efficient allocation of bandwidth, inability to address such capacity constraints in a timely manner may adversely affect our business, results of operations, financial position and cash flows.

The growth of our wireless data businesses has been a significant factor in the increased utilization of our bandwidth, since wireless data applications are generally more bandwidth-intensive than voice services. This trend has been offset in part by the implementation of CDMA 1xEV-DO upgrades to our CDMA 1xRTT network and, more recently, the completion of our HSDPA-capable WCDMA network, which both enable more efficient usage of our bandwidth than was possible on our basic CDMA and CDMA 1xRTT networks. However, if the current trend of increased data transmission use by our subscribers continues, or the volume of the multimedia content we offer through our wireless data services substantially grows, our bandwidth capacity requirements are likely to increase. In the event we are unable to maintain sufficient bandwidth capacity, our subscribers may perceive a general slowdown of wireless services. Growth of our wireless business will depend in part upon our ability to manage effectively our bandwidth capacity and to implement efficiently and in a timely manner new bandwidth-efficient technologies if they become available. We cannot assure you that bandwidth constraints will not adversely affect the growth of our wireless business.

 

We may have to make further financing arrangements to meet our capital expenditure requirements and debt payment obligations.

 

As a network-based wireless telecommunications provider, we have had, and expect to continue to have, significant capital expenditure requirements as we continue to build out, maintain and upgrade our networks. We estimate that we will spend approximately Won 1.75 trillion for capital expenditures in 2008 for a range of projects, including investments in our backbone networks (and expansion of our WiBro network in particular), investments to improve our WCDMA network-based products and services, investments in our wireless Internet-related and convergence businesses and funding for mid- to long-term research and development projects, as well as other initiatives, primarily related to our ongoing businesses and in the ordinary course. In 2008, we plan to continue HSUPA upgrades to our WCDMA network, as well as expand our WiBro service to “hot zone” areas in 42 cities. For a more detailed discussion of our capital expenditure plans and a discussion of other factors that may affect our future capital expenditures, see “Item 5.B. Liquidity and Capital Resources”.

 

At December 31, 2007, we had approximately Won 818.2 billion in contractual payment obligations due in 2008 of which almost all involve repayment of debt obligations. See “Item 5.F. Tabular Disclosure of Contractual Obligations”.

 

We have not arranged firm financing for all of our current or future capital expenditure plans and contractual payment obligations. We have, in the past, obtained funds for our proposed capital expenditure and payment obligations from various sources, including our cash flow from operations as well as from financings, primarily debt and equity financings. Inability to fund such capital expenditure requirements may have a material adverse effect on our financial condition, results of operations and business. In addition, although we currently anticipate that the capital expenditure levels estimated by us will be adequate to meet our business needs, such estimates may need to be adjusted based on developments in technology and markets. In the event we are unable to meet any such increased expenditure requirements or to obtain adequate financing for such requirements, on terms acceptable to us, or at all, this may have a material adverse effect on our financial condition, results of operations and business.

 

Termination or impairment of our relationship with a small number of key suppliers for network equipment and for leased lines could adversely affect our results of operations, financial position and cash flows.

 

We purchase wireless network equipment from a small number of suppliers. We purchase our principal wireless network equipment from Samsung Electronics Co., Ltd. and LG Nortel Co., Ltd. To date, we have purchased substantially all of the equipment for our CDMA 1xRTT and CDMA 1xEV-DO networks from Samsung Electronics and substantially all of the equipment for our WCDMA network, including the software and firmware used to implement HSDPA and HSUPA upgrades, from Samsung Electronics and LG Nortel. In addition, to date, we have purchased substantially all of the equipment for our WiBro network from Samsung Electronics. We believe Samsung Electronics currently manufactures approximately half of the wireless handsets sold to our subscribers. Although other manufacturers sell the equipment we require, sourcing such equipment from other manufacturers could result in unanticipated costs in maintenance and upkeep of the CDMA 1xRTT, CDMA 1xEV-DO and WCDMA networks, as well as in the planned expansion of our WiBro network. Inability to obtain the needed

equipment for our networks in a timely manner may have an adverse effect on our business, financial condition, results of operations and cash flows.

 

In addition, we rely on KT Corporation and SK Networks to provide a substantial majority of the transmission lines we lease. For a more detailed discussion of the lines we lease from fixed-line operators, see “Item 4.B. Business Overview — Digital Cellular Network — Network Infrastructure”.

 

We cannot assure you that we will be able to continue to obtain the necessary equipment from one or more of our suppliers. Any discontinuation or interruption in the availability of equipment from our suppliers for any reason could have an adverse effect on our results of operations. Inability to lease adequate lines at commercially reasonable rates may impact the quality of the services we offer and may result in damage to our reputation and our business.

 

Our businesses are subject to extensive Government regulation and any change in Government policy relating to the telecommunications industry could have a material adverse effect on our results of operations, financial condition and cash flows.

 

All of our businesses are subject to extensive governmental supervision and regulation. The MIC has periodically reviewed the tariffs charged by wireless operators and has, from time to time, suggested tariff reductions. Although these suggestions are not binding, we have in the past implemented some degree of tariff reductions in response to MIC recommendations. After discussions with the MIC, we began to provide Caller ID service to our customers free of charge from January 1, 2006. In addition, after discussions with the MIC, effective September 1, 2004, we reduced our monthly plan-based fees by 7.1%. Based on the MIC’s recommendation, in January 2007, we and other wireless telecommunications providers, including KTF and LGT, reduced usage fees for wireless Internet services by 30%.

 

The Government also plays an active role in the selection of technology to be used by telecommunications operators in Korea. The MIC adopted the WCDMA and CDMA2000 technologies as the only standards available in Korea for implementing 3G services. The KCC may impose similar restrictions on the choice of technology used in future telecommunications services and it is possible that technologies promoted by the Government in the future may not provide the best commercial returns for us. In addition, the KCC may revoke our licenses or suspend any of our businesses if we fail to comply with its rules, regulations and corrective orders, including the rules restricting beneficial ownership and control and corrective orders issued in connection with any violation of rules restricting beneficial ownership and control or any violation of the conditions of our licenses. We believe we are currently in compliance with the material terms of all our cellular licenses, including our IMT-2000 and WiBro licenses.

 

Our wireless telecommunications services depend, in part, on our interconnection arrangements with domestic and international fixed-line and other wireless networks. Our interconnection arrangements, including the interconnection rates we pay and interconnection rates we charge, affect our revenues and operating results. The KCC determines the basic framework for interconnection arrangements, including interconnection policies relating to interconnection rates in Korea, and the MIC has changed this framework several times in the past. We cannot assure you that we will not be adversely affected by future changes in the KCC’s interconnection policies. See “Item 4.B. Business Overview — Interconnection — Domestic Calls”.

 

In January 2003, the MIC announced its plan to implement number portability with respect to wireless telecommunications service in Korea. The number portability system allows wireless subscribers to switch wireless service operators while retaining the same mobile phone number. In addition, in order to manage the availability of phone numbers efficiently and to secure phone number resources for the new services, the MIC has required all new subscribers to be given numbers with the ‘010’ prefix starting January 2004, and it has been gradually retracting the mobile service identification numbers which had been unique to each wireless telecommunications service provider, including ‘011’ for our cellular services. We believe that the use of the common prefix identification system has posed, and continues to pose, a greater risk to us compared to the other wireless telecommunications providers because, historically, ‘011’ has had high brand recognition in Korea as the premium wireless telecommunications service. The MIC’s adoption of the number portability system has resulted in and could continue to result in a deterioration of our market share as a result of weakened customer loyalty, increased competition among wireless service providers and higher costs of marketing as a result of maintaining the number portability system,

increased subscriber deactivations and increased churn rate, all of which had, and may continue to have, an adverse effect on our results of operations. See “Item 5. Operating and Financial Review and Prospects” and “Item 4.B. Business Overview — Law and Regulation — Competition Regulation — Number Portability”.

 

In the past, wireless telecommunications service providers provided handsets at below retail prices to attract new subscribers, offsetting a significant portion of the cost of handsets. The rapid growth in penetration rate in past years can, at least in part, be attributed to such subsidies on handsets given to new subscribers. During the period between June 2000 and March 2008, the MIC prohibited all wireless telecommunications service providers, subject to certain exceptions stipulated in the Telecommunications Business Act, from providing any such handset subsidies. The MIC has, on several occasions between March 2002 and February 2008, imposed various types of sanctions and fines against us and the other wireless service providers for violating restrictions on providing handset subsidies and other activities that were deemed to be disruptive to fair competition. We paid the fines and believe that we have complied in all material respects with the other sanctions imposed by the MIC. For details on these and other Government penalties, see “Item 8.A. Consolidated Statements and Other Financial Information — Legal Proceedings”. Beginning in March 2006 the MIC partially lifted, and, in March 2008 fully lifted, its prohibition on the provision of handset subsidies. We currently provide subsidies of between Won 130,000 to Won 170,000 to subscribers who enter into long-term subscription agreements of one to two years. As a result of the Government’s recent decision to allow handset subsidies, we have faced increased competition from other mobile service providers. The provision of handset subsidies has increased, and may continue to increase, our marketing expenses, which in turn, has had, and may continue to have, a material adverse effect on our results of operations.

 

In addition, the KCC may revoke our licenses or suspend any of our businesses if we fail to comply with its rules, regulations and corrective orders, including the rules restricting beneficial ownership and control and corrective orders issued in connection with any violation of rules restricting beneficial ownership and control or any violation of the conditions of our licenses. Alternatively, in lieu of suspension of our business, the KCC may levy a monetary penalty of up to 3% of the average of our annual revenue for the preceding three fiscal years. The revocation of our cellular licenses, suspension of our business or imposition of monetary penalties by the KCC could have a material adverse effect on our business. We believe we are currently in compliance with the material terms of all our cellular licenses.

 

We are subject to additional regulation as a result of our dominant market position in the wireless telecommunications sector, which could harm our ability to compete effectively.

 

The KCC’s policy is to promote competition in the Korean telecommunications markets through measures designed to prevent a dominant service provider in a telecommunications market from exercising its market power to prevent the emergence and development of viable competitors. We are currently designated by the KCC as the “market dominant service provider” in respect of our wireless telecommunications business. As such, we are subject to additional regulation to which certain of our competitors are not subject. For example, under current Government regulations, we must obtain prior approval from the KCC to change our existing rates or introduce new rates while our competitors may generally change their rates or introduce new rates at their discretion. See “Item 4.B. Business Overview — Law and Regulation — Competition Regulation — Rate Regulation”. We could also be required by the KCC to charge higher usage rates than our competitors for future services. In addition, we were required to introduce number portability earlier than our competitors, KTF and LGT. The MIC also awarded the IMT-2000 license to provide 3G services to LGT at a fee lower than our license fee and on terms generally more favorable than the terms of our license.

 

We qualify as a “market-dominating business entity” under the Fair Trade Act. The Fair Trade Commission of Korea, or the FTC, approved our acquisition of Shinsegi on various conditions, one of which was that our and Shinsegi’s combined market share of the wireless telecommunications market, based on numbers of subscribers, be less than 50% as of June 30, 2001. In order to satisfy this condition, we reduced the level of our subscriber activations and adopted more stringent involuntary subscriber deactivation policies beginning in 2000 and ceased accepting new subscribers from April 1, 2001 through June 30, 2001. Although we were no longer subject to any market share limitations, we voluntarily undertook to limit our market share to 52.3%, the level of our market share at the time of the approval of our merger with Shinsegi in January 2002, until the end of 2007. We can give no assurance that the Government will not impose restrictions on our market share in the future or that we will not

undertake to voluntarily restrict our market share in the future. If we are subject to market share limitations in the future, our ability to compete effectively will be impeded.

 

The additional regulation to which we are subject has affected our competitiveness in the past and may materially hurt our profitability and impede our ability to compete effectively against our competitors in the future.

 

Financial difficulties and charges of financial statement irregularities at our affiliate, SK Networks (formerly SK Global), may cause disruptions in our business.

 

Charges of financial statement irregularities by certain directors and executives at our affiliate SK Networks culminated in the resignation of four of our board members and executives in March 2004, although none of these resignations were related to any allegations of wrongdoing in connection with their role in our business. We were not implicated in any of the charges against SK Networks’ management. However, continuing financial difficulties at SK Networks could result in our having to look for alternative sources for handset distribution and fixed network line needs. In February, 2004, Mr. Kil Seung Son and Mr. Tae Won Chey, both of whom served on our board of directors at the time, were each sentenced to three-year prison terms by the Court of First Instance (which terms were suspended for five years by the Appellate Court) in connection with allegations of financial misconduct at SK Networks. In connection with such allegations, Mr. Kil Seung Son and Mr. Tae Won Chey resigned from our board of directors. The sentence of the Court of First Instance was affirmed by the Supreme Court in May 2008. See “Item 6.A. Directors and Senior Management — Involvement In Certain Legal Proceedings”.

 

In March 2003, the principal creditor banks of SK Networks commenced corporate restructuring procedures against SK Networks after the company announced that its financial statements understated its total debt by Won 1.1 trillion and overstated its profits by Won 1.5 trillion. In November 2003, SK Networks underwent a capital reduction and sold approximately Won 1 trillion of its assets as part of its restructuring plan, and SK Holdings Co., Ltd. (formerly known as SK Corporation) approved a Won 850 billion debt-for-equity swap. See “Item 7.A. Major Shareholders” for more information regarding the corporate reorganization of the entity formerly known as SK Corporation. SK Networks graduated from its debt restructuring program in April 2007.

 

SK Networks also serves as a distributor of handsets manufactured by third parties to our nationwide network of dealers. SK Networks was also the exclusive distributor of all of the handsets sold by our former subsidiary, SK Teletech, prior to our sale of the company to Pantech & Curitel in July 2005. Samsung Electronics Co., Ltd., LG Electronics Inc., Motorola Korea, Inc. and Pantech & Curital suspended their supply handsets to SK Networks for two to three weeks in April 2003 because of the credit risk of SK Networks. In May 2003, all suppliers resumed their supply of handsets on the condition that payment on their mobile phones be made in cash within one week of delivery. Although we believe that handset manufacturers will be able to find another distributor to replace SK Networks in the event SK Networks is no long able to distribute handsets, there may be difficulties in efficiently distributing handsets to our subscribers and other customers in the short term.

 

In addition, as of December 31, 2007, we leased a majority of our leased lines from SK Networks. For a more detailed discussion of the lines we lease from fixed-line operators, see “Item 4.B. Business Overview — Digital Cellular Network — Network Infrastructure”. If there is a material disruption of SK Networks’ ability to maintain and operate this business due to its financial difficulties, we may need to seek alternative sources, which may result in a disruption of our services in the short term, which, in turn, may have a material adverse effect on 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. We cannot assure you that these 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.

 

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.

 

We are incorporated in Korea and a significant portion of our operations is based in Korea. As a result, we are subject to political, economic, legal and regulatory risks specific to Korea. The economic indicators in Korea in recent years have shown mixed signs, and future growth of the Korean economy is subject to many factors beyond our control. Events related to the terrorist attacks in the United States on September 11, 2001, recent developments in the Middle East including the war in Iraq and its aftermath, higher oil prices, the general weakness of the global economy due in part to problems with the U.S. housing market and the reduced availability of credit in the U.S. have increased the uncertainty of global economic prospects and may continue to adversely affect the Korean economy. Any future deterioration of the Korean and global economy could adversely affect our business, financial condition, results of operations and cash flows.

 

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

 

 

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

 

Substantially all of our revenues are denominated in Won. Depreciation of the Won may materially affect our results of operations because, among other things, it causes:

 

 

Fluctuations in the exchange rate between the Won and the Dollar will affect the Dollar equivalent of the Won price of the shares of our common stock on the Stock Market Division of the Korea Exchange, or the KRX Stock Market. These fluctuations also will affect:

 

 

For historical exchange rate information, see “Item 3.A. Selected Financial Data — Exchange Rate”.

 

Increased tensions with North Korea could have an adverse effect on us and the prices of our common stock and the ADSs.

 

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 December 2002, North Korea removed the seals and surveillance equipment from its Yongbyon nuclear power plant and evicted inspectors from the United Nations International Atomic Energy Agency. 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 response, the United Nations Security Council passed a resolution that prohibits any United Nations member state from conducting transactions with North Korea in connection with any large scale arms and material or technology related to missile development or weapons of mass destruction and from providing luxury goods to North Korea, imposes an asset freeze and travel ban on persons associated with North Korea’s weapons program, and calls upon all United Nations member states to take cooperative action, including through inspection of cargo to or from North Korea. In response, North Korea agreed in February 2007 at the six-party talks to shut down and seal the Yongbyon nuclear facility, including the reprocessing facility, and readmit international inspectors to conduct all necessary monitoring and verifications. In October 2007, Korea and North Korea held a summit meeting to discuss easing tensions and fostering peace on the Korean peninsula. Mr. Lee Myung Bak, who became the President of Korea in February 2008, has announced that no further summit meetings will be held until North Korea discontinues its nuclear weapons program.

 

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, including a breakdown of high-level contacts between Korea and North Korea or

occurrence of military hostilities, could have a material adverse effect on our operations and the market value of our common shares.

 

If SK Holdings causes us to breach the foreign ownership limitations on shares of our common stock, we may experience a change of control.

 

There is currently a 49% limit on the aggregate foreign ownership of our issued shares. Under an amendment to the Telecommunications Business Act, which became effective in May 2004, a Korean entity, such as SK Holdings, is deemed to be a foreign entity if its largest shareholder (determined by aggregating the shareholdings of such shareholder and its related parties) is a foreigner and such shareholder (together with the shareholdings of its related parties) holds 15% or more of the issued voting stock of the Korean entity. As of March 31, 2008, SK Holdings owned 18,748,452 shares of our common stock, or approximately 23.09%, of our issued shares. If SK Holdings were considered to be a foreign shareholder, then its shareholding in us would be included in the calculation of our aggregate foreign shareholding and our aggregate foreign shareholding (based on our foreign ownership level as of March 31, 2008, which we believe was 48.19%) would exceed the 49% ceiling on foreign shareholding. As of March 31, 2008, a foreign investment fund and its related parties collectively held a 4.81% stake in SK Holdings. We could breach the foreign ownership limitations if the number of shares of our common stock or ADSs owned by other foreign persons significantly increases.

 

If our aggregate foreign shareholding limit is exceeded, the KCC may issue a corrective order to us, the breaching shareholder (including SK Holdings if the breach is caused by an increase in foreign ownership of SK Holdings) and the foreign investment fund and its related parties who own in the aggregate 15% or more of SK Holdings. Furthermore, if SK Holdings is considered a foreign shareholder, it may not exercise its voting rights with respect to the shares held in excess of the 49% ceiling, which may result in a change in control of us. In addition, the KCC may refuse to grant us licenses or permits necessary for entering into new telecommunications businesses until our aggregate foreign shareholding is reduced to below 49%. If a corrective order is issued to us by the KCC arising from the violation of the foregoing foreign ownership limit, and we do not comply within the prescribed period under such corrective order, the KCC may

 

 

The amendment to the Telecommunications Business Act in May 2004 also authorizes the KCC to assess monetary penalties of up to 0.3% of the purchase price of the shares for each day the corrective order is not complied with, as well as a prison term of up to one year and a penalty of Won 50 million. For a description of further actions that the KCC could take, see “Item 4.B. Business Overview — Law and Regulation — Foreign Ownership and Investment Restrictions and Requirements”.

 

If our convertible notes are converted by foreign holders and the conversion would cause a violation of the foreign ownership restrictions of the Telecommunications Business Act, or in certain other circumstances, we may sell common stock in order to settle the converting holders’ conversion rights in cash in lieu of delivering common stock to them, and these sales might adversely affect the market price of our common stock or ADRs.

 

In May 2004, we sold US$329.5 million in zero coupon convertible notes due 2009. As of March 31, 2008, these convertible notes were convertible by the holders into shares of our common stock at the rate of Won 204,636 per share. These notes are held principally by foreign holders. If (1) the exercise by the holder of the conversion right would be prohibited by Korean law or we reasonably conclude that the delivery of common stock upon conversion of these notes would result in a violation of applicable Korean law or (2) we do not have a sufficient number of shares of our common stock to satisfy the conversion right, then we will pay a converting holder a cash settlement payment. In such situations, we may sell such number of treasury shares held in trust for us that

corresponds to the number of shares of common stock that would have been deliverable in the absence of the 49% foreign shareholding restrictions imposed by the Telecommunications Business Act or other legal restrictions. The number of shares sold in these circumstances might be substantial. We cannot assure you that such sales would not adversely affect the market prices of our common stock or ADSs.

 

Sales of our shares by companies in the SK Group, POSCO and/or other large shareholders may adversely affect the prices of our common stock and ADSs.

 

Sales of substantial amounts of shares of our common stock, or the perception that such sales may occur, could adversely affect the prevailing market price of the shares of our common stock or ADSs or our ability to raise capital through an offering of our common stock.

 

As of December 31, 2007, POSCO owned 2.88% of our issued common stock. POSCO has not agreed to any restrictions on its ability to dispose of our shares. See “Item 7.A. Major Shareholders”. Companies in the SK Group, which collectively owned 23.09% of our issued common stock as of December 31, 2007, may sell their shares of our common stock in order to comply with the Fair Trade Act’s limits on the total investments that companies in a large business group, such as the SK Group, may hold in other domestic companies. See “Item 4.B. Business Overview — Law and Regulation — Competition Regulation”. We can make no prediction as to the timing or amount of any sales of our common stock. We cannot assure you that future sales of shares of our common stock, or the availability of shares of our common stock for future sale, will not adversely affect the market prices of the shares of our common stock or ADSs prevailing from time to time.

 

Korea’s legislation allowing class action suits related to securities transactions may expose us to additional litigation risk.

 

The Securities-related Class Action Act of Korea enacted in January 2004 allows class action suits to be brought by shareholders of companies (including us) listed on the KRX Stock Market for losses incurred in connection with purchases and sales of securities and other securities transactions arising from (i) false or inaccurate statements provided in the registration statements, prospectuses, business reports and audit reports and omission of material information in such documents; (ii) insider trading and (iii) market manipulation. This law permits 50 or more shareholders who collectively hold 0.01% of the shares of a company to bring a class action suit against, among others, the issuer and its directors and officers. It is uncertain how the courts will apply this law. Litigation can be time-consuming and expensive to resolve, and can divert management time and attention from the operation of a business. We are not aware of any basis under which such suit may be brought against us, nor are any such suits pending or threatened. Any such litigation brought against us could have a material adverse effect on our business, financial condition and results of operations.

 

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

 

Under the deposit agreement, holders of shares of our common stock may deposit those shares with the ADR depositary’s custodian in Korea and obtain ADSs, and holders of ADSs may surrender ADSs to the ADR depositary and receive shares of our common stock. However, under the terms of the deposit agreement, as amended, the depositary bank is required to obtain our prior consent to any such deposit if, after giving effect to such deposit, the total number of shares of our common stock on deposit, which was 1,317,494 shares as of March 31, 2008, exceeds a specified maximum, subject to adjustment under certain circumstances. In addition, the depositary bank or the custodian may not accept deposits of our common shares for issuance of ADSs under certain circumstances, including (1) if it has been determined by us that we should block the deposit to prevent a violation of applicable Korean laws and regulations or our articles of association or (2) if a person intending to make a deposit has been identified as a holder of at least 3% of our common stock on October 7, 2002. See “Item 10.B. Memorandum and Articles of Association — Description of American Depositary Shares”. It is possible that we may not give the consent. Consequently, an investor who has surrendered his ADSs and withdrawn the underlying shares may not be allowed to deposit the shares again to obtain ADSs.

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

 

The Korean Commercial Code and our articles of association 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 ADR depositary, 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 ADR depositary, 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:

 

 

We are under no obligation to file any registration statement with respect to any ADSs. 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, ADS holders may suffer dilution of their equity interest in us.

 

Short selling of our ADSs by purchasers of securities convertible or exchangeable into our ADSs could materially adversely affect the market price of our ADSs.

 

SK Holdings, through one or more special purpose vehicles, has engaged and may in the future engage in monetization transactions relating to its ownership interest in us. These transactions have included and may include offerings of securities that are convertible or exchangeable into our ADSs. Many investors in convertible or exchangeable securities seek to hedge their exposure in the underlying equity securities at the time of acquisition of the convertible or exchangeable securities, often through short selling of the underlying equity securities or through similar transactions. Since a monetization transaction could involve debt securities linked to a significant number of our ADSs, we expect that a sufficient quantity of ADSs may not be immediately available for borrowing in the market to facilitate settlement of the likely volume of short selling activity that would accompany the commencement of a monetization transaction. This short selling and similar hedging activity could place significant downward pressure on the market price of our ADSs, thereby having a material adverse effect on the market value of ADSs owned by you.

 

After the exchange of ADSs into our underlying common shares, seller or purchasers of the underlying common shares may have to pay securities transaction tax upon the transfer of the shares.

 

Under Korean tax law, transfer of a company’s common shares after the exchange of ADSs into our underlying common shares of will be subject to securities transaction tax (including an agricultural and fishery special tax) at the rate of 0.3% of the sales price if traded on the KRX Stock Market.

 

Securities transaction tax, if applicable, generally must be paid by the transferor of the shares or the person transferring rights to subscribe to such shares. When the transfer is effected through a securities settlement company, such settlement company is generally required to withhold and pay the tax to the tax authority. When such transfer is made through a securities company, such securities company is required to withhold and pay the tax. In case the sale takes place outside the KRX Stock Market, without going through a securities settlement company or a securities company, between two non-residents or between a non-resident seller and a Korean resident purchaser, the purchaser will have to withhold securities transaction tax at the rate of 0.5% of the sales price of the common shares.

 

Failing to report, or under-reporting, the securities transaction tax will result in a penalty of between 10% to 40% of the actual tax amount due, depending on the nature of the improper reporting. The failure to pay the securities transaction tax due will result in imposition of interest at 10.95% per annum on the unpaid tax amount for the period from the day immediately following the last day of the tax payment period to the day of the issuance of

the tax notice. The penalty is imposed on the party responsible for paying the securities transaction tax or, if the securities transaction tax is to be paid via withholding, the penalty is imposed on the party that has the withholding obligation. See “Item 10.E. Taxation — Korean Taxation”.

 

A holder of our ADSs may not be able to enforce a judgment of a foreign court against us.

 

We are a corporation with limited liability organized under the laws of Korea. Substantially all of our directors and officers and other persons named in this document reside in Korea, and all or a significant portion of the assets of our directors and officers and other persons named in this document and substantially all of our assets are located in Korea. As a result, it may not be possible for holders of our ADSs to effect service of process within the United States, or to enforce against them or us in the United States judgments obtained in United States courts based on the civil liability provisions of the federal securities laws of the United States. There is doubt as to the enforceability in Korea, either in original actions or in actions for enforcement of judgments of United States courts, of civil liabilities predicated on the United States federal securities laws.

 

We are generally subject to Korean corporate governance and disclosure standards, which may differ from those in other countries.

 

Companies in Korea, including us, are subject to corporate governance standards applicable to Korean public companies, which may differ in some respects from standards applicable in other countries, including the United States. As a reporting company registered with the Securities and Exchange Commission and listed on the New York Stock Exchange, we are, and in the future will be, subject to certain corporate governance standards as mandated by the Sarbanes-Oxley Act of 2002. However, foreign private issuers, including us, are exempt from certain corporate governance requirements under the Sarbanes-Oxley Act or under the rules of the New York Stock Exchange. There may also be less publicly available information about Korean companies, such as us, than is regularly made available by public or non-public companies in other countries. Such differences in corporate governance standards and less public information could result in corporate governance practices or disclosures that are perceived as less than satisfactory by investors in certain countries.

 

 

 

As Korea’s first wireless telecommunications service provider, we have a recognized history of leadership and innovation in the domestic telecommunications sector. Today, we remain Korea’s leading wireless telecommunications services provider and have continued to pioneer the commercial development and implementation of state-of-the-art wireless technologies. We have also strengthened our global competitiveness by expanding into key overseas markets and we continue to look outside Korea for investment and growth opportunities. We believe we are also a leader in developing new products and services that reflect the increasing convergence of telecommunications technologies, as well as the growing synergies between the telecommunications sector and other industries. One of our most recent efforts to pursue new opportunities in the convergence business area is our acquisition of an additional 38.6% stake in hanarotelecom, Korea’s second-largest fixed-line operator, which was completed in March 2008.

 

We provide our wireless telecommunications services principally through backbone networks using CDMA and WCDMA technology. These networks are, collectively, accessible to approximately 99% of the Korean population. In addition, we also provide wireless broadband Internet access through our WiBro service. For a more detailed description of our backbone network infrastructure, see “— Digital Cellular Network” below. Our advanced and extensive wireless telecommunications infrastructure has enabled us to offer high-quality cellular voice transmission services at competitive prices, as well as to develop and deploy an increasingly sophisticated range of wireless data and multimedia products and services, including wireless Internet services, in step with technological advancements and growing consumer demand. We believe our network infrastructure also provides us with a competitive advantage in pioneering new business opportunities created by digital convergence.

 

As of December 31, 2007, we had approximately 22.0 million subscribers throughout Korea, of which 19.3 million owned data-capable handsets, which are handsets that support cellular voice and data transmission. As

of December 31, 2007, our share of the Korean wireless market was approximately 50.5%, based on number of subscribers, according to the MIC.

 

On May 31, 2008, we had a market capitalization of approximately Won 16.5 trillion (US$15.8 billion, as translated at the noon buying rate of June 27, 2008) or approximately 1.60% of the total market capitalization on the KRX Stock Market, making us the eighth largest company listed on the KRX Stock Market based on market capitalization on that date. Our ADSs, each representing one-ninth of one share of our common stock, have traded on the New York Stock Exchange since June 27, 1996.

 

We established our telecommunications business in March 1984 under the name of Korea Mobile Telecommunications Co., Ltd., under the laws of Korea. We changed our name to SK Telecom Co., Ltd., effective March 21, 1997. In January 2002, Shinsegi, which was then the third-largest wireless telecommunications service provider in Korea, was merged into us. Our registered office is at 11, Euljiro 2-ga, Jung-gu, Seoul 100-999, Korea and our telephone number is 82-2-6100-2114.

 

Korean Telecommunications Industry

 

Established in March 1984, we became the first wireless telecommunications service provider in Korea. We remained the sole provider of wireless telecommunications services until April 1996, when Shinsegi commenced cellular service. The Government began to introduce competition into the fixed-line and wireless telecommunications services markets in the early 1990’s. During this period, the Government allowed new competitors to enter the fixed-line sector, sold a controlling stake in us to the SK Group, and granted a cellular license to our first competitor, Shinsegi. In October 1997, three additional companies, KTF, LGT, and Hansol PCS, began providing wireless services under Government licenses granting them the right to provide wireless telecommunications services.

 

In 2000 and 2001, the Korean wireless telecommunications market experienced significant consolidation. In January 2002, Shinsegi was merged into us. Additionally, two of the other wireless telecommunications services operators merged. See “Item 4.B. Business Overview — Competition”. Thus, there are currently three providers of wireless voice telecommunications services in Korea, us, KTF, which is a subsidiary of KT Corporation, and LGT. According to the MIC, as of December 31, 2007, we had 50.5% market share of the Korean wireless telecommunications market in terms of subscribers, while KTF and LGT had market shares of 31.5% and 18.0%, respectively.

 

In December 2000, the MIC awarded to two companies the right to receive a license to provide 3G services using WCDMA, an extension of the Global System for Mobile Communication standard for wireless telecommunications, which is the most widely used wireless technology globally. These rights were awarded to two consortia of companies, one led by our former subsidiary, SK IMT Co., Ltd., and the other to a consortium that included KT Corporation. SK IMT Co., Ltd. was merged into us on May 1, 2004. The right to acquire an additional license to operate a network using CDMA2000 technology was awarded to LGT in August 2001, but was later revoked in July 2006.

 

A one-way mobile number portability, or MNP, system was first implemented in the beginning of January 2004 when our subscribers were allowed to transfer to KTF and LGT. From July 2004, a two-way MNP was implemented so that KTF subscribers could transfer to us and LGT. A three-way MNP has been in effect since January 2005 so that subscribers from each of the wireless service providers may transfer to any other wireless service provider. During 2005, 2006 and 2007, approximately 2.2 million, 2.9 million and 3.4 million, respectively, of our subscribers transferred to our competitors. Approximately 0.7 million, 0.8 million and 1.1 million of LGT’s subscribers in 2005, 2006 and 2007, respectively, and approximately 1.5 million, 2.1 million and 2.3 million in 2005, 2006 and 2007, respectively, of KTF’s subscribers migrated to our service.

 

In January 2005, the Government granted KT Corporation and us a license to offer WiBro service. According to an MIC report published in April 2006, the number of WiBro subscribers is expected to rise to more than 8 million subscribers by the end of 2010.

 

Telecommunications industry growth in Korea has been among the most rapid in the world, with fixed-line penetration increasing from under five lines per 100 population in 1978 to 47.7 lines per 100 population as of

December 31, 2007, and wireless penetration increasing from 7.0 subscribers per 100 population in 1996 to 89.8 subscribers per 100 population as of December 31, 2007. The table below sets forth certain subscription and penetration information regarding the Korean telecommunications industry as of the dates indicated:

 

 

 

 

The Korean telecommunications industry is one of the most developed in the world in terms of wireless penetration and in terms of the growth of wireless data services, including wireless Internet services. The wireless penetration rate, which is calculated by dividing the number of wireless subscribers by the population, was 89.8% as of December 31, 2007 and the number of wireless subscribers has increased from approximately 3.2 million in 1996 to approximately 43.5 million as of December 31, 2007.

 

Since the introduction of short text messaging in 1998, Korea’s wireless data market has grown rapidly. This growth has been driven, in part, by the rapid development of wireless Internet service since its introduction in the second half of 1999. All of the Korean wireless operators have developed extensive wireless Internet service portals. As of December 31, 2007, approximately 11.1 million of Korean wireless subscribers owned Internet-enabled handsets capable of accessing advanced wireless Internet services. The table below sets forth certain penetration information regarding the number of Internet-enabled handsets and wireless subscribers in Korea as of the dates indicated:

In addition to its well-developed wireless telecommunications sector, Korea has one of the largest Internet markets in the Asia Pacific region. According to the Korea Network Information Center, or KRNIC, the number of Internet subscribers in Korea increased from approximately 3.1 million at the end of 1998 to approximately 34.8 million at the end of 2007, a 30.8% compound annual growth rate. From the end of 2003 to the end of 2007, the number of broadband Internet access subscribers increased from approximately 11.2 million to approximately 14.7 million, a 7.0% compound annual growth rate. The table below sets forth certain information regarding Internet users and broadband subscribers as of the dates indicated:

 

 

 

 

 

Overview

 

We are Korea’s leading wireless telecommunications services provider and continue to pioneer the commercial development and implementation of state-of-the-art wireless technologies. We had approximately 22.0 million subscribers as of December 31, 2007 and, in 2007, our share of the Korean wireless market was approximately 50.5%, based on the number of subscribers, according to the MIC. We provide the following core services:

 

 

In addition, we actively participate in various overseas markets, including in the United States, China and Vietnam.

 

We provide our core services through our proprietary backbone networks based on CDMA and WCDMA technology. We also offer wireless data transmission and wireless Internet access services through our WiBro network. For more information on our backbone networks, see “— Digital Cellular Network”.

 

Our Business Strategy

 

Core Business Strategies

 

We believe that trends in the Korean telecommunications industry during the next decade will mirror those in the global market and that the industry will be characterized by rapid technological change, reduced regulatory barriers and increased competition. Against the backdrop of these industry trends, we aim to enhance shareholder value by maintaining and consolidating our leading position in the Korean market for wireless services, including wireless voice and data transmission services, as well as by leveraging our competitive strengths to exploit new opportunities arising from increasing digital convergence and the globalization of the telecommunications market.

 

Our principal strategies are to:

 

 

 

Our Services

 

We offer wireless digital voice and data transmission services via networks that are, collectively, accessible to approximately 99% of the Korean population. We continually upgrade and increase the capacity of our wireless networks to keep pace with advancements in technology, the growth of our subscriber base and the increased usage of voice and wireless data services by our subscribers.

 

We first introduced digital cellular service using CDMA technology in January 1996 and substantially completed the geographic build-out of our basic CDMA network in 1998. In October 2000, we began offering 2G wireless voice and data transmission services on our more advanced CDMA 1xRTT network, which we then fully upgraded to the even more advanced CDMA 1xEV-DO technology, beginning in 2002. Our CDMA networks cover 84 cities nationwide, or approximately 99% of the Korean population.

We launched WCDMA services, our 3G wireless voice and data transmission services, in 2003. In 2005, we completed commercial development of HSDPA technology and integrated this technology in the subsequent build-out of our WCDMA network. HSDPA, which represents an evolution of the WCDMA standard, is a more advanced 3G technology than the initial WCDMA technology we implemented and is sometimes referred to as “3.5G” technology. In March 2007, we completed nationwide expansion of our HSDPA-capable WCDMA network, which currently reaches approximately 99% of the Korean population. In June 2007, we commenced a further upgrade of our WCDMA network to support HSUPA technology. We expect these updates to be complete by the end of 2009. Our WCDMA network enables significantly faster and higher-quality voice and data transmission than our 2G networks and supports more sophisticated wireless data transmission services, including video telephony and other multimedia communications. We believe these enhanced transmission capabilities may encourage increased subscriber usage of our wireless data transmission services.

 

We also began to offer wireless broadband Internet access through our WiBro service in May 2006. A data-only transmission technology, WiBro supports wireless data transmission at even higher speeds than possible on our WCDMA network. We believe that our WiBro service will complement our other wireless telecommunications services by allowing us to enhance our data transmission service options in metropolitan areas where there is a high demand for large packet data services, particularly wireless Internet access. We currently offer WiBro service to “hot zone” areas in 23 cities in Korea and plan to expand coverage to hot zone areas in 42 cities by the end of 2008.

 

For a more complete discussion of our backbone networks, see “— Digital Cellular Network” below.

 

Cellular Voice Services

 

Our cellular voice services, which comprise basic wireless voice transmission services and related “value-added” services, as well as global roaming services, remain our core business area. We derive revenues from our cellular voice services principally through initial subscription fees, plan-specific monthly fees, usage fees and value-added service fees. For a more complete description of the fees we charge, see “— Revenues, Rates and Facility Deposits” below.

 

To complement our basic voice transmission services, in recent years, we have begun to offer increasingly sophisticated and differentiated subscriber-oriented value-added services made possible due to rapid advancements in network technology. Our most popular value-added voice-related services in 2006 included services that provide a record of missed calls in the event a subscriber’s mobile phone is engaged or switched off, known as our “Call Keeper” service; services that play a “ring back” melody in lieu of a conventional dial tone when callers dial a subscriber’s mobile phone, known as “COLORing” service, as well as COLORing services that periodically change the default ring-back melody according to the subscriber’s music category selection, known as “Auto COLORing” service; and services that alert subscribers when a dialed number that was engaged when first dialed, is no longer engaged.

 

T-Roaming Services.  We also offer cellular global roaming services, branded as our “T-Roaming” service, through service agreements with various foreign wireless telecommunications service providers. Global roaming services allow subscribers traveling abroad to make and receive calls, often using their regular mobile phone numbers. Subscribers using EV-DO- and WCDMA-capable handsets are able to make and receive calls using their regular mobile phone number without changing their handsets. In addition, we provide global roaming service to foreigners travelling to Korea. In such cases, we generally receive a fee from the traveller’s local wireless service provider.

 

Our global roaming service is offered in three basic technologies, in part depending on which mobile phone standards are available in a particular region: CDMA, GSM and WCDMA roaming. We currently offer CDMA voice roaming services in 20 countries, including countries in Asia, North and South America, as well as, Guam, Saipan and New Zealand; GSM voice roaming services in 155 countries, including countries in Europe, North America, Africa, the Middle East and Asia; and WCDMA voice roaming services in 54 countries, including countries in Asia, Europe, the Middle East, Africa and Australia. In addition, we offer CDMA global data roaming services in 8 countries, including China, Japan, Taiwan, Thailand, Indonesia, Vietnam, Guam and Saipan, and WCDMA global data roaming services in 49 countries in Asia, Europe, the Middle East and Africa. In 2007,

approximately 3.0 million subscribers utilized our global roaming services. The global roaming service we provide to foreigners traveling to Korea is generally WCDMA-based.

 

In addition, we provide interconnection service to connect our networks to domestic and international fixed-line and other wireless networks. See “— Interconnection” below.

 

Wireless Data Services (including Wireless Internet Services)

 

Our wireless data transmission services represent a key and growing business area. We currently offer our subscribers wireless data communications services, as well as wireless access to a wide variety of digital content and services, including Internet-based content and services. We intend to continue to build our wireless data services as a platform for growth, extending our portfolio of wireless data services and developing new content for our subscribers.

 

SMS and MMS Services.  We provide wireless data communication services, including our basic short text message service, or SMS, which allows subscribers to send and receive short text messages to and from their mobile phones. SMS, which is also known as our “phone mail” service, continues to be one of our most popular data transmission services. In addition to text-only SMS, we also offer a multimedia message service, or MMS. MMS allows subscribers to send and receive multimedia messages containing graphic, audio and video clips to and from their mobile phones. While MMS is possible through our CDMA 1 x EV-DO network, the implementation of WCDMA technology has significantly increased the quality, speed and range of our multimedia message services.

 

Wireless Internet Services.  In addition to our wireless data communications services, we also offer our subscribers wireless access to the Internet, primarily through our “NATE” portal, which is our integrated wired and wireless Internet platform that utilizes wireless application protocol, or WAP, technology, to provide a gateway between our cellular network and the Internet. Through our NATE portal, subscribers can access a wide variety of multimedia contents and interactive services, as well as send and receive email and instant text and multimedia messages, using their mobile phones and other wireless devices. As of December 31, 2007, approximately 19.3 million, or 87.7%, of our subscribers owned WAP-enabled handsets capable of accessing our CDMA 1xRTT network, or any of our more advanced networks.

 

 

 

Since November 2002, we have also provided our subscribers access to multimedia content through “June”, a wireless data service that provides streaming content, primarily using our CDMA 1xEV-DO technology.

Content provided through the June service includes digital video and music downloads; television programs, which can be viewed real-time; June subscribers with EV-DO- or WCDMA-capable handsets can also access the Internet through NATE.

 

 

 

 

Digital Convergence and New Businesses

 

Digital convergence is the new paradigm in telecommunications. While we acknowledge the increasing equivocation of conventional industry boundaries as a potential threat, given the entrance of non-traditional players into the mobile communications space, we also view convergence as significant growth opportunity. We believe that incumbent telecommunications service providers, like us, with existing advanced infrastructure, technical know-how and a large subscriber base, are especially well positioned to pioneer new “convergent” businesses. In recent years, we have focused on developing cross-over services that provide synergies with our existing business.

 

One of our most recent efforts to pursue new opportunities in the convergence business area is our acquisition of an additional 38.6% stake in hanarotelecom for Won 1.1 trillion in March 2008. hanarotelecom is Korea’s second-largest fixed-line operator and currently provides fixed-line telephone and broadband-based Internet services. hanarotelecom also operates “Hana TV”, a video-on-demand service and plans to roll out real-time Internet protocol TV, or IP TV, services in the future. We are hoping to benefit from a range of synergies from this acquisition, including by offering our customers bundled fixed-line and mobile telecommunications services. We also believe the acquisition creates opportunities to aggregate and broadcast digital content across various media platforms.

 

Our other convergence services include:

 

Satellite DMB Business.  In September 2003, we entered into an agreement with Mobile Broadcasting Corporation for the purposes of co-owning and launching a satellite for the satellite DMB business. Under the terms of the agreement, we were committed to fund 34.7% of the cost of launching and maintaining the operations of the satellite. The acquisition cost of the satellite was approximately Won 205.2 billion, of which our portion was Won 71.2 billion. DMB technology allows broadcasting of multimedia content through transmission by satellite to various mobile devices. For example, DMB technology allows users to view satellite television broadcasts on

mobile phones, portable handsets or vehicle-mounted televisions that are enabled to receive DMB transmission. TU Media is currently developing new convergence services that combine wireless telecommunications technologies with traditional broadcasting contents, advertising contents and retail services. We believe that this business will enable us to improve the breadth of wireless multimedia services that we already offer and remain competitive in the face of increasing convergence in the telecommunications and broadcasting industries.

 

We launched a satellite DMB in March 2004. In October 2004, we granted the right to use the satellite DMB to our then-affiliate, TU Media. TU Media began to provide commercial satellite DMB service in May 2005 and today remains Korea’s sole operator of satellite digital mobile broadcasting services. TU Media currently offers a range of broadcast content including education, games, drama, music, news and culture over more than 35 channels, including TUBOX, a pay-per-view movie channel that broadcasts movies before their DVD release. As of December 31, 2007, TU Media had more than 1.3 million subscribers.

 

In February 2007, we purchased 4,615,798 new shares of TU Media for Won 32.4 billion, increasing our equity interest from 29.6% as of December 31, 2006 to 32.7%. Following this equity investment, TU Media became our consolidated subsidiary. In March 2008, we made an additional Won 55.0 billion capital contribution to TU Media, increasing our equity interest to 44.2%. We are currently TU Media’s largest shareholder.

 

Telematics Service.  In February 2002, we introduced a Telematics service called T-Map Navigation. T-Map Navigation is an interactive navigation service that uses GPS technology and our NATE platform to transmit driving directions, real-time traffic updates and emergency rescue assistance to wireless devices, including vehicle-mounted devices and portable handsets.

 

We believe that Telematics also creates opportunities for synergy between mobile telecommunications and other industries. Under an agreement entered into in April 2002 with Renault Samsung Motors and Samsung Electronics, we are co-developing a customized Telematics system for use in Renault Samsung vehicles. The implementation of more advanced 3G transmission technologies has also facilitated the increased integration of our wireless platforms customized for vehicular use and, in particular, created synergies between our Telematics services and satellite DMB broadcasting services. We offer bundled Telematics and satellite DMB broadcasting services through a single, integrated vehicle-mounted device.

 

We are currently developing additional applications for our telematics service in cooperation with companies in the logistics and insurance industries. We also see potential applications of Telematics technology in the tourism industry. In December 2004, we launched Telematics service on Jeju Island and, in August 2005, were selected as the pilot Telematics service provider for Jeju Island as part of the MIC and Jeju Island’s joint effort to showcase the island as a model for Telematics service.

 

Global Business

 

We actively participate in various overseas markets, particularly in the United States, China and Vietnam. We continue to seek opportunities to expand our global business, primarily through joint ventures and other strategic alliances with local partners.

 

Our global business strategy is to focus primarily on those regions in which we have already made strategic investments. However, we will also continue to study new opportunities for expansion into new regions abroad.

 

United States.  On March 24, 2005, we and EarthLink, a major Internet services provider in the United States, completed the formation of HELIO, LLC. (formerly named SK-EarthLink LLC.), a Delaware limited liability company, to provide wireless voice and data services in the United States. We hold our interests in HELIO through our wholly-owned U.S. subsidiary, SK Telecom USA Holdings, Inc. Together with our joint venture partner, EarthLink, we made a combined initial investment in HELIO of US$440 million in cash and non-cash assets.

 

In July 2007, we and EarthLink entered into a lending agreement with HELIO pursuant to which we and EarthLink could lend up to US$200 million to HELIO, and each made an initial loan to HELIO of US$30 million. In November 2007, we and EarthLink cancelled such lending agreement and HELIO issued to each of us a US$30 million secured exchangeable promissory note, bearing interest at 10% per annum and payable at maturity

in July 2010. The notes are exchangeable for membership units of HELIO at any time up to the maturity date. The notes may also be prepaid by HELIO at any time without penalty.

 

In November 2007, we and EarthLink also amended and restated HELIO’s joint venture agreements, whereby we agreed to make up to US$270 million in additional equity contributions to HELIO. In February 2008, HELIO’s joint venture agreements were further amended to make certain modifications to the terms of the outstanding membership interests owned by us, EarthLink and the other HELIO investors. In 2007 and the first quarter of 2008, we made additional equity contributions of US$150 million, in aggregate, to HELIO. As a result, as of March 31, 2008, we were HELIO’s largest shareholder, with a 68.8% equity interest in the company. As of the same date, EarthLink, HELIO’s second-largest shareholder, held a 27.9% equity interest.

 

In June 2008, we and EarthLink entered into an agreement with Virgin Mobile USA, Inc., a leading provider of wireless communications services in the United States that was founded as a joint venture between Sprint Nextel and the Virgin Group, and certain of its affiliates, pursuant to which Virgin Mobile USA, Inc. and certain of its affiliates agreed to acquire our aggregate equity interest in HELIO. As consideration, we and EarthLink will acquire limited partnership units of Virgin Mobile USA, L.P. (Virgin Mobile USA, Inc.’s operating company), equivalent to 13 million shares of Virgin Mobile USA, Inc.’s Class A common stock (valued at approximately US$39 million). This transaction is expected to close in the third quarter of 2008, subject to regulatory approvals and the satisfaction of other closing conditions. In addition, in June 2008, we and the Virgin Group agreed to each invest US$25 million of equity capital in Virgin Mobile USA, Inc. in exchange for mandatory convertible preferred stock, convertible into Virgin Mobile USA, Inc.’s Class A common stock, pending the approval of Virgin Mobile USA, Inc.’s shareholders. The preferred shares will carry a four-year maturity and a 6% annual dividend. Upon the approval of Virgin Mobile USA, Inc.’s shareholders, the preferred stock will convert into Class A common shares when the shares reach the conversion price of US$8.50 per share or upon maturity.

 

HELIO is a non-facilities-based nationwide mobile virtual network operator (“MVNO”) offering cellular voice and data services to wireless consumers by renting networks from network operators. HELIO commercially launched its MVNO services extensively across the United States in May 2006. HELIO taps into the previously under-served but rapidly growing wireless data, entertainment, and voice market in the United States, also leverages our expertise in developing and implementing 3G technology and other cutting-edge applications and EarthLink’s established sales channels, Wi-Fi experience, network data centers and billing capabilities. As of March 31, 2008, HELIO had approximately 186,000 subscribers.

 

Since December 2004, we have been offering our COLORing solution to Verizon Wireless, a major mobile phone service provider in the United States. As an application service provider, we receive an agreed percentage of Verizon’s COLORing service related revenues.

 

China.  In February 2004, we and China Unicom, the second largest telecom operator and the only CDMA-based telecommunications service provider in China, established a joint venture company called UNISK Information Technology Co., Ltd., with an aggregate initial investment of approximately US$6 million. We own a 49% stake of UNISK and China Unicom holds a 51% stake. UNISK offers wireless Internet service in China under a brand name that means “community of young elites” in Chinese. In addition, on July 5, 2006, we purchased US$1 billion in aggregate principal amount of zero coupon convertible bonds issued by China Unicom, convertible into common shares of China Unicom. In August 2007, we converted such bonds into shares representing a 6.6% equity interest in China Unicom to become China Unicom’s second-largest shareholder. In May 2008, China Unicom announced that it may merge with China NetCom, a leading broadband communications and fixed-line telecommunications operator in China. The merger remains subject to approval by the board of directors of China Unicom during a meeting expected to be held in September 2008. In the event the merger is consummated, we expect our equity interest in China Unicom to decrease to 3.8% from 6.6%.

 

In July 2004, we, through our subsidiary U-Land Company Ltd., acquired ViaTech, an Internet portal service and mobile contents provider in China, to enhance our wireless Internet contents and expand our service area. Through ViaTech, we offer a Chinese-language version of Cyworld to subscribers in China. ViaTech had more than 4 million Cyworld subscribers as of December 31, 2007.

In August 2006, we entered into a memorandum of understanding with China’s National Development and Reform Commission to assist China develop TD-SCDMA technology, China’s 3G standard. To support joint research and development in 3G multimedia services, value-added services and development of the TD- SCDMA network, we and the Chinese government established a research and development center in Beijing in February 2007. To further facilitate the commercialization and implementation of TD-SCDMA, we also opened a TD-SCDMA test center in Bundang, Korea in April 2007.

 

In February 2008, we, through our wholly-owned Chinese subsidiary, SK Telecom China Holding Company, invested Won 13.9 billion to acquire a 65.5% equity interest in Shenzhen E-eye High Tech Co., Ltd., a global positioning system service company in China. We believe the acquisition of Shenzhen E-eye High Tech will allow us to leverage opportunities created by the rapidly growing telematics market in China.

 

In March 2008, we acquired a 42.2% equity interest in TR Music, a major record label in China, for US$10.7 million. In addition, in May 2008 we invested US$7.8 million to acquire a 30.0% equity interest in Magic Tech Network, a Hong Kong company that develops and publishes online games in China.

 

Vietnam.  With a wireless telecommunications service penetration rate of only 46% as of December 31, 2007, we believe that the Vietnamese mobile communication market offers significant opportunity for future growth. In July 2003, our subsidiary, SKT Vietnam PTE Ltd., entered into a business cooperation contract with Saigon Post & Telecommunication Services Corporation to establish a joint venture company, S-Telecom, to provide mobile telecommunications services and commercial CDMA service, the first of its kind in Vietnam, under the brand name “S-Fone”. Pursuant to such contract, in the event that the cash inflow for the business is insufficient to cover the cash outflow necessary to cover the expenditures necessary to operate the business, SKT Vietnam and Saigon Post & Telecommunication Services Corporation have agreed to equally contribute the necessary working capital. We held a 73.3% equity interest in SKT Vietnam as of December 31, 2007. With respect to our involvement in S-Telecom, our maximum exposure to loss was approximately Won 167.6 billion as of December 31, 2007.

 

In December 2005, SKT Vietnam began expanding the CDMA network to all of Vietnam in order to meet the needs of a growing subscriber base. By September 2006, network coverage was expanded to cover all 64 provinces, including Ho Chi Min and Hanoi. S-Fone had approximately 3.5 million subscribers as of December 31, 2007 and had a 9.0% market share according to Vietnam’s Ministry of Posts and Telematics, based on the number of wireless subscribers in Vietnam, as of such date.

 

Mongolia.  In July 1999, we acquired a 27.8% equity interest in Skytel Co., Ltd., Mongolia’s second-largest cellular service provider, by providing approximately Won 1.5 billion worth of analog infrastructure. We, together with Skytel, have been providing cellular service in Mongolia since July 1999, and CDMA service since February 2001. In April 2001, we completed installation of the equipment necessary to provide WAP service. In December 2002, we increased our equity interest in Skytel to 28.6% through the subscription of newly issued common shares in return for an additional investment of approximately US$500,000. As of December 31, 2007, our equity interest in Skytel was 26.4%.

 

Regional and International Strategic Alliances.  We have also entered into various strategic alliances with leading companies in the Asian and European wireless telecommunications markets. For instance, we are a member of the Bridge Alliance, the largest pan-Asian alliance of its kind, which includes eleven of the region’s leading wireless service providers. In June 2007, we also signed a memorandum of understanding with the Freemove Alliance, an alliance of leading European wireless service providers, including Orange SA of France, Telecom Italia Mobile S.p.A. of Italy, T-Mobile International AG & Co. AG of Germany and Teliasonera Mobile Networks AB of Sweden, for the development of expanded WCDMA-based roaming service in Europe. We plan to continue improving customer service as well as service quality, by developing co-marketing programs and other joint projects with our regional and global partners and by further fostering our regional and international alliances.

 

Provision of Wireless Internet Platforms and Cellular Network Solutions to Foreign Cellular Network Operators.  We have also sought to expand our global business through sales of our wireless Internet platforms and cellular network solutions, as well as provision of consulting services in the field of mobile communications. For example, in July 2004, we entered into an agreement with TA Orange, a GSM-based mobile communications operator in Thailand, to provide wireless Internet platforms, including our NATE portal platform, for

US$6.3 million. We completed this project in June 2005. In addition, we have also been successful in exporting to other Asian countries and the United States, the technological solutions underlying certain value-added and other wireless services, such as our color mail solution, which is a messaging service that allows subscribers to send messages containing multimedia files containing graphic, audio and video clips.

 

Other Products and Services

 

International Calling Services.  Through our 90.8% owned subsidiary, SK Telink Co., Ltd., we provide international telecommunications services, including direct-dial as well as pre- and post-paid card calling services, bundled services for corporate customers, voice services using Internet protocol, Web-to-phone services, and data services. SK Telink provides affordable international call services under the brand name “00700” and has been offering commercial long-distance telephony service since February 2005. SK Telink also offers Voice over Internet Protocol, or VoIP, service through the Internet. VoIP is an advanced technology that transmits voice data through an Internet Protocol network. SK Telink also operates certain value-added domestic telephone services, including a “080” service that allows companies to establish “toll-free” customer service telephone hotlines, for which all call charges would be paid by the company, as well as a “general corporate number” service that automatically routes calls made to a company’s general telephone number to the caller’s nearest local branch.

 

Other Portal Services.

 

 

In March 2004, we launched “Mobile Cyworld”, allowing wireless subscribers to access the Cyworld portal community site through their cellular phones.

 

In November 2007, SK Communications merged with Empas Corp., an internet search engine and portal site. We believe the merger will create valuable convergence synergies among our NATE, Cyworld and Empas services.

 

Revenues, Rates and Facility Deposits

 

Our wireless revenues are generated principally from initial subscription fees, monthly plan-based fees, usage charges for outgoing voice calls, usage charges for wireless data services, value-added-service fees and

interconnection revenue. The following table sets forth information regarding our cellular revenues (net of taxes) and facility deposits for the periods indicated:

 

 

 

 

We charge our new customers an initial subscription fee for initial connection and service activation. In addition to the initial subscription fee, we require our customers to pay monthly plan-based fees, usage charges for outgoing voice calls and usage charges for wireless data services. We do not charge our customers for incoming calls, although we do receive interconnection charges from KT Corporation and other companies for calls from the fixed-line network terminating on our networks and interconnection revenues from other wireless network operators. See “— Interconnection”. Monthly plan-based fees for some plans include free airtime and/or discounts for designated calling numbers.

 

We offer a variety of differentiated Standard Rate Plans that are designed to meet a wide range of subscriber needs and interests. Popular Standard Rate Plans include our couples discount plan, region discount plan and friends and family discount plan. The basic monthly fee for our Standard Rate Plans ranges from Won 9,900 to Won 90,000.

 

In addition, we offer optional “add-on” service plans, which may supplement the basic service plan a subscriber has chosen, including:

 

 

We also offer discounts to subscribers committing to long-term contracts. To long-term subscribers who initially became our subscribers as a result of Shinsegi’s merger into us in January 2002 and who continue to remain our subscribers, we offer discounts on monthly plan-based fees ranging from 5% to 20%. For all other long-term subscribers, we offer discounts on usage charges ranging from 5% to 10%.

We began to provide Caller ID service to customers free of charge commencing January 1, 2006. Also, effective September 1, 2004, we reduced our tariffs by 3.7% and reduced our monthly plan-based fees by 7.1%, resulting in a decrease in the monthly fee for our basic standard rate plan from Won 14,000 to Won 13,000. In January 2007, we reduced our usage fees for wireless Internet services by 30% and, in October 2007 we reduced usage fees for voice calls between our subscribers by 50%. In addition, in January 2008 we reduced our SMS usage charges from Won 30 per message to Won 20 per message. See “Item 5.A. Operating Results — Overview”.

 

For all calls made from our subscribers’ handsets in Korea to any destination in Korea, we charge usage fees based on a subscriber’s cellular rate plan. The fees are the same whether the call is local or long distance. With respect to international calls placed by a subscriber, we bill the subscriber the international rate charged by the Korean international telephone service provider through which the call is routed. We remit to that provider the international charge less our usage charges. See “— Interconnection”.

 

We offer a variety of value-added services, including our COLORing, Auto COLORing, Call Keeper and Perfect Call services. Depending on the rate plan selected by the subscriber, the monthly fee may or may not include these value-added services, except Caller ID and call waiting services, which are offered free of charge to all beginning subscribers.

 

We offer wireless Internet access services to our subscribers through NATE. Subscribers using our CDMA network may elect to pay a monthly fee, which includes a fixed amount of airtime or data packets, or may elect to pay on a variable, usage basis. Standard usage rates for NATE range from Won 7 to Won 15 for ten seconds of airtime. Since April 23, 2001, a subscriber using our CDMA 1xRTT and CDMA 1xEV-DO networks is charged based on the amount of data that is transmitted to such subscriber’s handset. Subscribers using our WCDMA network are also charged based on the amount of data transmitted. The data transmitted is measured in packets of 512 bytes. We charge Won 4.55 per text packet, Won 0.9 per multimedia packet, for large volume data transfers, and Won 1.75 per multimedia packet, for smaller volume data transfers. In addition, we charge subscribers for purchases of certain digital contents and for certain wireless services, such as m-commerce transaction services.

 

We generally require new subscribers (other than certain corporate and Government subscribers) to pay a non-interest bearing facility deposit of Won 200,000, which we may utilize to offset a defaulting subscriber’s outstanding account balance. In lieu of paying the facility deposit, subscribers who meet the credit qualifications required by the Seoul Guarantee Insurance Company may elect to be covered under insurance provided by the Seoul Guarantee Insurance Company. We pay a Won 10,000 premium to the Seoul Guarantee Insurance Company on behalf of such subscribers. Seoul Guarantee Insurance Company reimburses us up to Won 350,000 for each insured subscriber that defaults on any payment obligations. We refund the facility deposit to any existing subscriber who had initially made a facility deposit and later elects the facility insurance option. We bill subscribers on a monthly basis and subscribers may make payment at a bank, post office, any of our regional headquarters or sales offices, or at any of our authorized dealers. As a result of the facility insurance program, we have refunded a substantial amount of facility deposits, and facility deposits decreased from Won 61.8 billion as of December 31, 2000 to Won 6.4 billion as of December 31, 2007. We do not expect to have to refund a significant amount of facility deposits in the future, because we believe that most of our subscribers who wish to be covered by the Seoul Guarantee Insurance Company have already elected to so.

 

Because we have been designated by the MIC as a “market dominant service provider”, any modification to our fees, charges or the terms and condition of our service, including promotional rates and facility deposits, requires prior approval by the MIC.

 

We also charge our customers a 10.0% value-added tax. We can offset the value-added tax we collect from our customers against value-added tax refundable to us by the Korean tax authorities. We remit taxes we collect from our customers to the Korean tax authorities. We record revenues in our financial statements net of such taxes.

Subscribers

 

We had 22.5 million subscribers as of April 30, 2008, representing a market share of 50.5%, the largest market share among Korean wireless service providers. We believe that, historically, our subscriber growth has been due to many factors, including:

 

 

The following table sets forth selected historical information about our subscriber base for the periods indicated:

 

 

 

 

We had 22.0 million subscribers as of December 31, 2007. For the year ended December 31, 2007, we had 8.3 million activations and 6.6 million deactivations, representing an average monthly churn rate of 2.6% during the same period. Our subscribers include those subscribers who are temporarily deactivated, including (1) subscribers who voluntarily deactivate temporarily for a period of up to three months no more than twice a year and (2) subscribers with delinquent accounts who may be involuntarily deactivated up to two months before permanent deactivation, which we determine based on various factors, including prior payment history.

 

Market Share Limitations

 

As a condition to our merger with Shinsegi consummated in January 2002, we were required to comply with certain market share limitations imposed by the FTC. Although we were no longer subject to mandatory market share limitations, until the end of 2007, we voluntarily limited our market share to no more than 52.3%, which was the combined market share held by us and Shinsegi at the time the MIC approved the merger. We can give no assurance that the Government will not impose restrictions on our market share in the future. If we are subject to market share limitations in the future, our ability to compete effectively will be impeded, and our subscriber growth rate may decline.

 

Number Portability

 

Prior to January 2003, Korea’s wireless telecommunications system was based on a network-specific prefix system, in which a unique prefix was assigned to all the phone numbers of a specific network operator. We were assigned the “011” prefix, and all of our subscriber’s mobile phone numbers began with “011” (former Shinsegi subscribers use the “017” prefix) and our subscribers could not change their wireless phone service to another

wireless operator and keep their existing numbers. In January 2003, the MIC announced a plan to implement number portability with respect to wireless telecommunications services in Korea, allowing wireless subscribers to switch wireless service operators while retaining the same mobile phone number. Subscribers who switch operators using different frequencies, however, may be required to purchase a new handset. We use frequencies that are different from those used by KTF and LGT, while KTF and LGT use the same frequencies. As mandated by the MIC, we were the first wireless telecommunications provider to introduce number portability in January 1, 2004, allowing our customers to transfer their numbers to our competitors. Our competitors’ customers were not able to transfer their number to our service, however, until KTF and LGT introduced number portability beginning July 1, 2004 and January 1, 2005, respectively. Subscribers who choose to transfer to a different wireless operator have the right to return to their original service provider without paying any penalties within 14 days of their initial transfer.

 

In 2005, 2006 and 2007, respectively, approximately 2.2 million, 2.9 million and 3.4 million subscribers switched their wireless telecommunications service provider from us to KTF or LGT and approximately 2.2 million, 2.8 million and 3.4 million subscribers switched from KTF or LGT to us.

 

In 2005, 2006 and 2007, respectively, we gained approximately 0.7 million, 0.7 million and 1.7 million new subscribers, which represented approximately 42.5%, 39.9% and 51.4% of the aggregate number of new wireless subscribers gained by us, KTF and LGT in each year.

 

In addition, in order to manage the availability of phone numbers efficiently and to secure phone number resources for the services, the MIC has begun to integrate mobile telephone identification numbers into a common prefix identification number “010” and to gradually retract the current mobile service identification numbers which had been unique to each wireless telecommunications service provider, including “011” for our cellular services, starting from 2004. All new subscribers were given the “010” prefix starting January 2004. We believe that the adoption of the common prefix identification system has had, and may continue to have, a greater negative effect on us than on our competitors because, historically, “011” has had very high brand recognition in Korea as the premium wireless telecommunications service. Adoption of the number portability system has resulted in, and may continue to result in, increased competition among wireless service providers, increased subscriber deactivations, increased churn rates and higher marketing costs.

 

For 2007, our churn rate ranged from 2.0% to 3.2%, with an average churn rate of 2.6% for 2007, compared to an average churn rate of 2.0% for 2006. We cannot assure you that our churn rates will not increase in the future. See “Item 3.D. Risk Factors — Our businesses are subject to extensive Government regulation and any change in Government policy relating to the telecommunications industry could have a material adverse effect on our results of operations and financial condition”. In addition, for details regarding certain fines imposed on us by the MIC in connection with our marketing efforts related to the number portability system, see “Item 8.A. Consolidated Statements and Other Financial Information — Legal Proceedings — MIC Proceedings”.

 

Marketing and Service Distribution

 

Marketing, Sales and Service Network

 

We market our services and provide after-sales service support to customers through 29 sales centers, 45 branch offices and a network of 1,173 authorized exclusive dealers located throughout Korea. Our dealers are connected via computer to our database and are capable of assisting customers with account information. In addition, approximately 200,000 independent retailers (principally handset dealers) assist new subscribers to complete activation formalities, including processing subscription applications and accepting facility deposits or arranging for insurance with Seoul Guarantee Insurance Company.

 

Currently, authorized dealers are entitled to an initial commission for each new subscriber registered by the dealer, as well as an average ongoing commission calculated as a percentage of that subscriber’s monthly plan-based and usage charges from domestic calls for the first four years. In order to strengthen our relationships with our exclusive dealers, we offer a dealer financing plan, pursuant to which we provide to each authorized dealer an interest-free or low-interest loan of up to Won 2.0 billion with a repayment period of up to three years. As of December 31, 2007, we had an aggregate of Won 115 billion in loans to authorized dealers outstanding.

When we were the only cellular service provider in Korea, we were able to maintain a low level of marketing and advertising expenses. However, over the last several years, competition in the wireless telecommunications business has caused us to increase significantly our marketing and advertising expenses and, with continuing competition, we expect that such expenses will remain high. In 2005, 2006 and 2007, advertising expenditures amounted to 2.6%, 2.8% and 3.3% of our revenues, respectively.

 

Marketing Strategies and Marketing Information Management

 

Next Generation Marketing Project.  In December 2003, we launched our “Next Generation Marketing” project to develop more effective marketing strategies and to implement related improvements to our information technology systems and infrastructure. In connection with this project, we have, from time to time, engaged third-party service providers to provide information technology consulting, design and other related services. In particular, in June 2005, we entered into a Won 53.5 billion agreement with SK C&C Co., Ltd. to provide such marketing-related information technology consulting and design services. The Next Generation Marketing project was completed in October 2006. Information technology improvements we have implemented in connection with this project include the introduction of more advanced and integrated accounts receivable, accounts payable and customer relationship management systems, as well as more effective information security controls. We believe these upgrades have enhanced our ability to process and utilize marketing- and subscriber-related data, which, in turn, has helped us to develop more effective and targeted marketing strategies, as well as improved the overall accuracy and management of certain financial data.

 

We currently operate a customer information system designed to provide us with an extensive customer database. Our customer information system includes a billing system that provides us with comprehensive account information for internal purposes and enables us to efficiently respond to customer requests. Our customers can also change their service plans, verify the charges accrued on their accounts, receive their bills online and send text messages to our other subscribers through our website at www.tworld.co.kr.

 

New “T”-brand Marketing Strategy.  To increase brand awareness and promote our corporate image, in August 2006, we launched our “T”-brand marketing campaign. Our new “T” brand signifies the centrality of “Telecommunications” and “Technology” to our business and also seeks to emphasize our commitment to providing “Top” quality, “Trustworthy” products and services to our customers. We have begun to market all new products and services under the “T” brand, while brands existing prior to August 2006 will be re-branded and gradually integrated under the “T” brand umbrella.

 

Interconnection

 

Our networks interconnect with the public switched telephone networks operated by KT Corporation, hanarotelecom incorporated, DACOM Corporation and KINX, as well as the networks of the other wireless telecommunications service providers in Korea. These connections enable our subscribers to make and receive calls from telephones outside our networks. Under Korean law, service providers are required to permit other service providers to interconnect to their networks. If a new service provider desires interconnection with the networks of an existing service provider but the parties are unable to reach an agreement within 90 days, the new service provider can appeal to the Korea Communications Commission, a governmental agency under the MIC.

 

For 2005, our total interconnection revenues were Won 898.6 billion and our total interconnection expenses were Won 989.4 billion. For 2006, our total interconnection revenues were Won 1,033.4 billion and our total interconnection expenses were Won 1,014.9 billion. For 2007, our total interconnection revenues were Won 1,062.2 billion and our total interconnection expenses were Won 1,078.7 billion.

 

Domestic Calls

 

Guidelines issued by the MIC require that all interconnection charges levied by a regulated carrier take into account (i) the actual costs to that carrier of carrying a call or (ii) imputed costs. The interconnecting parties are required to calculate the relevant imputed costs on an annual basis. In the event of a dispute regarding the imputed costs, the Korea Communications Commission is empowered to act as arbitrator.

Wireless-to-Fixed-line.  According to our interconnection arrangement with KT Corporation, for a call from our wireless network to KT Corporation’s fixed-line network, we collect the usage rate from our wireless subscriber and in turn pay KT Corporation the interconnection charges based on KT Corporation’s imputed costs.

 

Fixed-line-to-Wireless.  The MIC determines interconnection arrangements for calls from a fixed-line network to a wireless network. For a call initiated by a fixed-line user to one of our wireless service subscribers, the fixed-line network operator collects our usage fee from the fixed-line user and remits to us an interconnection charge. Interconnection with KT Corporation accounts for substantially all of our fixed-line-to-wireless interconnection revenue and expenses.

 

In July 2004, the MIC introduced a new method of calculating interconnection rates for calls from fixed-line networks to wireless networks, based on the long-run incremental cost of each wireless service provider, taking into consideration technology development and future expected costs. The long-run incremental cost method has been adopted by other countries such as the United States, the United Kingdom and Japan. The interconnection rates paid by fixed-line network service providers to each wireless network service provider are set out below. The MIC announced the interconnection rates for 2007 in September 2006. Interconnection rates for 2008 are expected to be decided in September 2008 and once decided, will be applied retroactively to January 1, 2008.

 

 

The impact on our operations of the decrease in our interconnection rate for 2007 was more than offset by an increase in incoming call volume in 2007, which resulted in an overall increase of Won 28.8 billion in interconnection revenues. Our interconnection expenses, however, also increased in 2007 by Won 63.8 billion, primarily due to higher subscriber numbers resulting in higher call volume. The Won 63.8 billion increase in interconnection expenses includes the increase in the mobile-to-mobile interconnection expenses that were paid to other wireless service providers.

 

Wireless-to-Wireless.  The MIC implemented interconnection charges for calls between wireless telephone networks in Korea starting in January 2000. Under these arrangements, the operator originating the call pays an interconnection charge to the operator terminating the call. For all operators, the amount of the charge is derived from our imputed cost, which was Won 31.19 per minute, Won 33.13 per minute and Won 32.78 per minute for 2005, 2006 and 2007, respectively. Our revenues from the wireless-to-wireless charge were Won 502.7 billion in 2005, Won 606.8 billion in 2006 and Won 651.5 billion in 2007. Our expenses from these charges were Won 644.6 billion in 2004, Won 748.8 billion in 2005, Won 737.5 billion in 2006 and Won 784.7 billion in 2007. The charges above were agreed among the parties involved and confirmed by the MIC.

 

International Calls

 

With respect to international calls, if a call is initiated by a wireless subscriber, we bill the wireless subscriber for the international charges of KT Corporation, DACOM or hanarotelecom, and we receive interconnection charges from such operators. If an international call is received by our subscriber, KT Corporation, DACOM or hanarotelecom pays interconnection charges to us based on our imputed costs.

 

International Roaming Arrangements

 

To complement the services we provide to our subscribers in Korea, we offer international voice and data roaming services. We charge our subscribers usage fees for global roaming service and, in turn, pay foreign wireless network operators fees for the corresponding usage of their network. For a more detailed discussion of our global roaming services, see “— Our Services — Cellular Voice Services” above.

Digital Cellular Network

 

We offer wireless voice and data telecommunications services throughout Korea using digital wireless networks, including a CDMA network, which currently reaches approximately 99% of the population, a CDMA 1xRTT/CDMA 1xEV-DO network, which currently reaches approximately 90% of the population, an HSDPA-capable WCDMA network, which currently reaches approximately 99% of the population and a WiBro network, which currently services “hot zone” districts in 23 cities in Korea.

 

CDMA Networks

 

CDMA technology is a continuous digital transmission technology that accommodates higher throughput than analog technology by using various coding sequences to allow concurrent transmission of voice and data signals for wireless communication. In January 1996, we launched our first wireless network based on CDMA technology and became the world’s first to commercialize CDMA cellular service. Our CDMA-based network infrastructure has been the core platform for our wireless telecommunications business.

 

CDMA technology is currently in commercial operation in several countries including Korea, Hong Kong and the United States. A majority of the digital wireless networks currently in use around the world are based on either the European Global System for Mobile Communication standard or other time division multiple access technologies. Unlike the continuous digital transmission method of CDMA technology, these technologies break voice signals into sequential pieces of a defined length, place each piece into an information conduit at specific intervals and then reconstruct the pieces at the end of the conduit.

 

CDMA 1xRTT and CDMA 1x EV-DO Networks

 

In October 2000, we began offering wireless voice and data services on our CDMA 1xRTT network. CDMA 1xRTT is an advanced CDMA-based technology that allows transmission of data at speeds of up to 144 Kbps (compared to a maximum of 64 Kbps for our basic CDMA network).

 

Unlike our CDMA network, our CDMA 1xRTT network has been designed to allow upgrades in step with advances in wireless technology. In the first half of 2002, we launched an upgrade of our CDMA 1xRTT network to a more advanced technology called CDMA 1xEV-DO. CDMA 1xEV-DO is a CDMA-based technology, similar to CDMA 1xRTT, but which enables data to be transmitted at speeds of up to 2.4 Mbps. This higher transmission speed permits interactive transmission of data required for videophone services, a high-speed wireless Internet connection, as well as a multitude of multimedia services. In 2004, we completed the full upgrade of our CDMA 1xRTT network to CDMA 1xEV-DO technology. For details of our capital expenditures relating to CDMA 1xRTT and CDMA 1xEV-DO, see “Item 5.B. Liquidity and Capital Resources”.

 

WCDMA Network

 

WCDMA is a 3G, high capacity wireless communication system that enables us to offer an even wider range of telecommunications services, including cellular voice communications, video telephony, data communications, multimedia services, wireless Internet connection, automatic roaming and satellite communications. We commenced provision of our 3G services using on our HSDPA-upgraded WCDMA network on a limited basis in Seoul at the end of 2003. In March 2005, we developed and launched dual band/dual mode handsets, to offer seamless nationwide 3G service, an important factor for a nationwide deployment of WCDMA services.

 

In 2005, we completed commercial development of HSDPA technology and integrated this technology in the subsequent build-out of our WCDMA network. HSDPA, which represents an evolution of the WCDMA standard, is a more advanced 3G technology than the initial WCDMA technology we implemented and is sometimes referred to as “3.5G” technology. In March 2007, we completed nationwide expansion of our HSDPA-capable WCDMA network, which currently reaches approximately 99% of the Korean population. Our WCDMA network enables significantly faster and higher-quality voice and data transmission and supports more sophisticated wireless data transmission services, including video telephony and other multimedia communications, than is possible through our 2G networks. In June 2007, we began HSUPA upgrades to our WCDMA network and expect such upgrades to be complete by the end of 2009. HSUPA technology represents yet the next stage in the evolution of the WCDMA

standard. In particular, while HSDPA enables significantly improved downlink data transmission speeds, HSUPA permits faster uplink speeds. Our implementation of HSDPA and HSUPA technology will allow us to offer significantly improved, and a wider range of, wireless data transmission services, including more sophisticated multimedia digital contents and products. We also plan to continue enhancing our 3G service quality in 2008, including through the installation of additional small cell sites or cellular repeaters to improve reception quality in subterranean areas, buildings or any remaining “blind spots” where reception quality may not be optimal. For more information about our capital expenditures relating to our WCDMA-based network, see “Item 5.B. Liquidity and Capital Resources”, and for more information about risks relating to our WCDMA-based network, see “Item 3.D. Risk Factors — Implementation of 3G technology has required, and may continue to require, significant capital and other expenditures, which we may not recoup and such technology may be difficult to integrate with our existing technology and business”.

 

WiBro

 

We have also received a license from the MIC to provide wireless broadband, or WiBro services, which we believe will complement our existing networks and technologies. WiBro is a data-only transmission technology that enables high-speed wireless broadband access to portable computers, mobile phones and other portable devices. We conducted initial pilot testing of WiBro service in limited areas of metropolitan Seoul in May 2006 and currently service “hot zone” areas in 23 cities. “Hot zone” areas are districts and neighborhoods that are characterized by high levels of wireless data traffic, primarily financial districts and university environs. We plan to further expand service to hot zone areas in 42 cities by the end of 2008. Beyond 2008, our WiBro expansion plans will depend, in part, on subscriber demand for WiBro services.

 

Network infrastructure

 

The principal components of our wireless networks are:

 

 

As of December 31, 2007, our CDMA, CDMA 1RTT, CDMA 1xEV-DO, WCDMA and WiBro networks had an aggregate of 16,099 cell sites.

 

We purchase our principal digital wireless equipment for our CDMA networks from LG Electronics and Samsung Electronics. We have purchased substantially all of the equipment for our CDMA 1xRTT and CDMA 1xEV-DO networks from Samsung Electronics and have purchased substantially all of the equipment for our WCDMA network, including the software and firmware used to implement HSDPA and HSUPA upgrades, from Samsung Electronics and LG Nortel. We have purchased substantially all of the equipment for our WiBro network from Samsung Electronics.

 

Most of the transmission lines we use, including virtually all of the lines linking switching stations, as well as a portion of the lines linking cell sites to switching stations, comprise optical fiber lines that we own and operate directly. However, we have not undertaken to install optical fiber lines to link every cell site and switching station. In places where we have not installed our own transmission lines, we lease lines from SK Networks, KT Corporation and, to a lesser extent, hanarotelecom, LG Powercomm Co., Ltd. and Dreamline. Under applicable Korean law,

those Korean fixed-line operators that satisfy applicable conditions regarding market share and sales volume set forth in the Telecommunications Business Act may not decline to provide leased line services to us without reasonable cause.

 

We use a cellular network surveillance system. This system oversees the operation of cell sites and allows us to monitor our main equipment located throughout the country from one monitoring station. The automatic inspection and testing provided to the cell sites lets the system immediately rebalance to the most suitable setting, and the surveillance system provides automatic dispatch of repair teams and quick recovery in emergency situations.

 

Other Investments and Relationships

 

We have investments in several other businesses and companies and have entered into various business arrangements with other companies. Our principal investments fall into the following categories:

 

Wireless Content Providers and Application Providers

 

As part of our strategy to develop additional applications and content for our wireless data services, we invest in companies which develop wireless applications and provide Internet content, including content accessible by users of our wireless networks.

 

Digital Content Providers.  We also hold investments in companies that develop content for use in our fixed-line and wireless Internet businesses, particularly in the entertainment sector, to better capture growth opportunities arising from the provision of varied, high-quality digital contents. As wireless data transmission services have become increasingly important in the growth of our business, we are seeking to secure valuable mobile data and digital contents by making equity investments in various content providers.

 

We currently hold a 37.1% equity interest in iHQ Inc., an entertainment management firm that produces films, manages entertainers and operates online game services. We also hold a 60.0% stake in Loen Entertainment Inc. (formerly, Seoul Records Inc.), Korea’s largest music recording company in terms of records released and revenues. In July, 2007, we also acquired a 66.7% equity interest in Ntreev Soft Co., Ltd., an online game developer, particularly known for its multi-player sports games and anime-based games. Through our investments in companies such as iHQ, Loen Entertainment and Ntreev Soft, we are able to offer customers of our MelOn, Cizle and Gaming portal services access to an expanded range of music- and entertainment-related digital contents and mobile games, respectively.

 

In July and October 2005, we and certain other Korean investment companies invested an aggregate Won 40 billion to establish three funds to invest in the music industry and seek strategic partnerships with recording companies. As of December 31, 2007, our contribution to the funds amounted to Won 40 billion. Furthermore, in September, October and December 2005, we and co-investors invested an aggregate Won 55.8 billion to establish four movie-production funds to strengthen our ability to obtain movie content. We had invested Won 28.5 billion in the funds as of December 31, 2007. Such investments reflect our business strategy of diversification into new areas, such as media and entertainment.

 

Wireless Application Developers.  We hold investments in companies that help enable us to further develop and improve our wireless applications and multimedia platforms. In particular, we have invested in developers of wireless financial, or m-commerce, services, including companies that provide wireless billing solutions; developers of wireless modem devices; and developers of Internet search applications.

 

Other Investments

 

Our other investments include:

 

 

 

For more information regarding our investment securities, see note 4 of the notes to our consolidated financial statements.

 

Competition

 

We were Korea’s only provider of cellular telecommunications services until April 1996, when Shinsegi began offering its CDMA service. In 1996, the Government issued three additional licenses to KTF, LGT and Hansol PCS to operate CDMA services. Each of KTF, LGT and Hansol PCS commenced operation of its CDMA service in October 1997.

 

Beginning in 2000, there has been considerable consolidation in the wireless telecommunications industry, resulting in the emergence of stronger competitors. In 2000, KT Corporation acquired 47.9% of Hansol M.Com’s outstanding shares and renamed the company KT M.Com. KT M.Com merged into KTF in May 2001. In May 2002, the Government sold its remaining 28.4% stake in KT Corporation.

 

Significant advances in technology are occurring that may affect our businesses, including the roll-out or the planned roll-out by us and our competitors of advanced high-speed wireless telecommunications networks based on technologies including CDMA 1xEV-DO, WCDMA, CDMA2000 and WiBro.

 

See “Item 3.D., Risk Factors — Competition may reduce our market share and harm our results of operations and financial condition”.

 

As of December 31, 2007, according to the MIC, KTF and LGT had 13.7 million and 7.8 million subscribers, respectively, representing approximately 31.5% and 18.0%, respectively, of the total number of wireless subscribers in Korea on such date. As of December 31, 2007, we had 22.0 million subscribers, representing a market share of approximately 50.5%.

 

For a description of the risks associated with the competitive environment in which we operate, see “Item 3.D. Risk Factors — Competition may reduce our market share and harm our results of operations and financial condition”.

 

Under a multilateral agreement on basic telecommunications services among the members of the World Trade Organization effective November 1997, the Government has agreed to gradually reduce the restrictions on foreign and individual shareholdings in telecommunications service providers, including us, in Korea. The relevant Korean law, the Telecommunications Business Act, was amended to give effect to the provisions of the WTO agreement. While the WTO agreement enables us to seek foreign investors and strategic partners and to more easily take advantage of opportunities for investments in overseas telecommunications projects, it may also benefit our competitors and further intensify competition in the domestic market.

Law and Regulation

 

Overview

 

Korea’s telecommunications industry is subject to comprehensive regulation by the KCC, which is responsible for information and telecommunications policies, radio and broadcasting management. The KCC regulates and supervises a broad range of communications issues, including:

 

 

Pursuant to an amendment to the Government Organization Act, effective as of February 29, 2008, the Ministry of Information and Communication, or “MIC”, has recently become the Ministry of Knowledge Economy, and functions formerly performed by the MIC are now performed separately by the Ministry of Knowledge Economy, the Ministry of Culture, Sports and Tourism, the Ministry of Public Administration and Security, and, particularly, the KCC. In this report, we refer to the MIC as the relevant governmental authority in connection with any approval granted or action taken by the MIC prior to such amendment and to such other relevant governmental authority in connection with any approval granted or action taken by such other relevant governmental authority subsequent to such amendment.

 

Telecommunications service providers are currently classified into three categories: network service providers, value-added service providers, and specific service providers. We are classified as a network service provider because we provide telecommunications services with our own telecommunications networks and related facilities. As a network service provider, we are required to obtain a license from the KCC for each of the services we provide. Our licenses permit us to provide cellular services and third generation wireless services using WCDMA and WiBro technology. Our cellular license does not provide for a fixed term, our IMT-2000 license is valid for 15 years starting from 1999 and our WiBro license is valid for seven years starting from 2005.

 

The KCC may revoke our licenses or suspend any of our businesses if we fail to comply with its rules, regulations and corrective orders, including the rules restricting beneficial ownership and control and corrective orders issued in connection with any violation of rules restricting beneficial ownership and control or any violation of the conditions of our licenses. Alternatively, in lieu of suspension of our business, the MIC may levy a monetary penalty of up to 3% of the average of our annual revenue for the preceding three fiscal years. A network services provider that wants to cease its business or dissolve must obtain KCC approval.

 

In May 2007, the MIC issued a request for comments on a proposal to amend the enforcement regulations under the Telecommunications Business Act. Under the proposed amendment, many telecommunications services would fall under a broad class of “transmission services”. As a result, currently licensed telecommunications service providers would be able to provide local, long-distance and international telephone services, as well as broadband Internet access and Internet phone services, without additional business licenses. The proposed amendment to the enforcement regulations under the Telecommunications Business Act is currently being considered by the KCC .

In the past, the MIC has stated that its policy was to promote competition in the Korean telecommunications market 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. While all network service providers are subject to KCC regulation, we are subject to increased regulation because of our position as the dominant wireless telecommunications services provider in Korea.

 

Competition Regulation

 

The Korea Communications Commission is charged with ensuring that network service providers engage in fair competition and has broad powers to carry out this goal. If a network service provider is found to be in violation of the fair competition requirement, the Korea Communications Commission may take corrective measures it deems necessary, including, but not limited to, prohibiting further violations, requiring amendments to the articles of association or to service contracts with customers, and requiring the execution or performance of, or amendments to, interconnection agreements with other network service providers.

 

In addition, we qualify as a market dominating business entity under the Fair Trade Act. Accordingly, we are prohibited from engaging in any act of abuse, such as unreasonably determining, maintaining or altering service rates, unreasonably controlling the rendering of services, 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.

 

Because we belong to the SK Group, which is a large business group, we are subject to the following restrictions under the Fair Trade Act:

 

 

Number Portability.  Previously, Korea’s wireless telecommunications system was based on a network-specific prefix system in which a unique prefix was assigned to all the phone numbers of a network operator. We were assigned the “011” prefix, and all of our subscriber’s mobile phone numbers began with “011” (former Shinsegi subscribers use the “017” prefix). Our subscribers could not change their wireless phone service to another wireless operator and keep their existing numbers. In January 2003, the MIC announced its plan to implement number portability with respect to wireless telecommunications services in Korea. The number portability system allows wireless subscribers to switch wireless service operators while retaining the same mobile phone number. However, subscribers who switch operators must purchase a new handset, as we use a different frequency than KTF and LGT. In accordance with the plan published by the MIC, the number portability system was adopted by us starting from January 1, 2004. KTF and LGT introduced number portability beginning on July 1, 2004 and January 1, 2005, respectively. For details of the number of subscribers who transferred to the services of our competitors following the implementation of the number portability system, see “— Subscribers”.

 

In addition, in order to manage the availability of phone numbers efficiently and to secure phone number resources for the new services, the MIC has begun to integrate mobile telephone identification numbers into a common prefix identification number “010” and to gradually retract the current mobile service identification numbers which had been unique to each wireless telecommunications service provider, including “011” for our cellular services, starting from January 1, 2004. All new subscribers have been given the “010” prefix starting January 2004. For details of the number of new subscribers for each of the major wireless cellular providers following the adoption of the “010” prefix January 2004, see “— Subscribers”.

 

For risks relating to number portability, see “Item 3.D. Risk Factors — Our businesses are subject to extensive Government regulation and any change in Government policy relating to the telecommunications industry could have a material adverse effect on our results of operations and financial condition”.

 

Prohibitions on Handset Subsidies.  Until March 26, 2006, when an amendment to the Telecommunications Business Act came into effect, telecommunications service providers had been prohibited from providing handset subsidies to attract new subscribers under the Telecommunications Business Act. From March 27, 2006 until March 27, 2008, when the prohibition on handset subsidies was fully lifted, the prohibition on handset subsidies was subject to the following exceptions:

 

 

Accordingly, until March 2008 we were permitted to provide handset subsidies only to our subscribers who had been using our services uninterruptedly for at least 18 months, or to our subscribers who were subscribing to our HSDPA or WiBro services. The Telecommunications Business Act required any telecommunications service provider seeking to provide handset subsidies to report to the KCC the qualifying criteria and range of subsidy payments no later than 30 days prior to the effective date of the applicable subsidy payment. Following the full-lifting of handset subsidies in March 2008, telecommunications service providers are no longer subject to the restrictions described above.

 

Rate Regulation.  Most network service providers must report to the KCC the rates and contractual terms for each type of service they provide, but generally they may set rates at their discretion. However, as the dominant network services provider for specific services (based on having the largest market share in terms of number of subscribers and meeting certain revenue thresholds), we must obtain prior approval of our rates and terms of service from the KCC. In each of the years in which this requirement has been applicable, the MIC has designated us for wireless telecommunications service and KT Corporation for local telephone and Internet services, as dominant network service providers subject to this approval requirement. As a condition to its approval of our merger with SK

IMT, the MIC required that we submit the rates for our third generation mobile services using WCDMA technology to the MIC for approval prior to the launch of such services. The KCC’s policy is to approve rates if they are appropriate, fair and reasonable and if they are calculated in a transparent and appropriate manner. It may order changes if it deems the rates to be significantly unreasonable or against public policy.

 

On April 9, 2003, the MIC announced its plan to adopt a “reserved reporting” system for setting new rates as a measure to relax the stringent regulation on pricing. Under the “reserved reporting” system, we would have to report our proposed new rate plan with the KCC in order to change our rates. Unless the KCC objects to the proposed rate plan within a certain period of time, such rates would be automatically adopted. We believe that this system, if implemented, would give us greater flexibility in setting our wireless communications service rates in response to market conditions in a timely manner, but we can give no assurance that such a system will be adopted as currently contemplated, or at all, or that the rates allowed by such a system will allow us to remain profitable.

 

Furthermore, in 2007, the MIC announced a “road map” highlighting revisions in regulations to promote deregulation of the telecommunications industry. In accordance with the road map and pursuant to the Combined Sales Regulation, promulgated in May, 2007, telecommunications service providers are now permitted to bundle their services, such as wireless data service, wireless voice service, broadband Internet access service and fixed-line telephone service, at a discounted rate; provided, however, that we and KT Corporation, which are designated as market-dominating business entities under the Telecommunications Business Act, allow other competitors to employ the services provided by us and KT Corporation, respectively, so that such competitors can provide similar discounted package services. The road map also includes plans to amend the regulations and provisions under the Telecommunications Business Act to permit licensed transmission service providers to offer local, domestic long-distance and international telephone services, as well as broadband Internet access and Internet phone services, without additional business licenses. The proposed amendment is currently being considered by the KCC. The introduction of bundled services may increase competition in the telecommunications sector, as well as cause downward price pressure on the fees we charge for our services, which, in turn, may have a material adverse effect on our results of operations.

 

Interconnection.  Dominant network service providers such as ourselves that own essential infrastructure facilities or that possess a certain market share are required to provide interconnection of their telecommunications network facilities to other service providers upon request. The KCC sets and announces the standards for determining the scope, procedures, compensation and other terms and conditions of such provision, interconnection or co-use. We have entered into interconnection agreements with KT Corporation, DACOM, Onse and other network service providers permitting these entities to interconnect with our network. We expect that we will be required to enter into additional agreements with new operators as the KCC grants permits to additional telecommunications service providers.

 

Frequency Allocation.  The KCC has the discretion to allocate and adjust the frequency band for each type of service. Upon allocation of new frequency bands or adjustment of frequency bands, the KCC is required to give a public notice. The KCC also regulates the frequency to be used by each radio station, including the transmission frequency used by equipment in our cell sites. All of our frequency allocations are for an indefinite term. We pay fees to the KCC for our frequency usage that are determined based upon our number of subscribers, frequency usage by our networks and other factors. For 2005, 2006 and 2007, the fee amounted to Won 156.1 billion, Won 159.0 billion and Won 164.1 billion, respectively.

 

In addition, we paid Won 650 billion of the Won 1.3 trillion cost of the IMT-2000 license in March 2001 and are required to pay the remainder of the license cost in annual installments for a five-year period from 2007 through 2011. For more information, see note 2(k) and note 8 of the notes to our consolidated financial statements for the years ended December 31, 2005, 2006 and 2007.

 

Mandatory Contributions and Obligations

 

Contributions to the Fund for Development of Information Telecommunications.  The Ministry of Knowledge Economy has the authority to recommend to network service providers that they provide funds for national research and development of telecommunications technology and related projects. For 2007, the MIC recommended that we

contribute 0.75% of budgeted revenues (calculated pursuant to MIC guidelines that differ from our accounting practices) to the Fund for Development of Information Telecommunications operated by the MIC.

 

In May 2002, the MIC announced significant changes to the Government contribution system. Starting from 2002, the contributions became mandatory, and the annual contribution which was set at 1.0% of total revenues for the previous year was lowered to 0.5% (0.75% for market dominant service providers like us) of total revenues for the previous year, and will be applicable only to those network service providers who have Won 30 billion in total sales for the previous year and have recorded no net loss in the current period. Under the policy, the maximum amount of the annual contribution to be made cannot exceed 70% of the net profit for the corresponding period of each company. Our contribution to this fund in 2005, 2006 and 2007 was Won 68.5 billion, Won 66.1 billion and Won 73.7 billion, respectively, based on the new MIC requirement of 0.75% of MIC-calculated revenues.

 

Universal Service Obligation.  All telecommunications service providers other than value-added service providers, specific service providers and regional paging service providers or any telecommunications service providers whose net annual revenue is less than an amount determined by the KCC (currently set at Won 30 billion) are required to provide “universal” telecommunications services including local telephone services, local public telephone services, telecommunications services for remote islands and wireless communication services for ships and telephone services for the handicapped and low-income citizens, or contribute toward the supply of such universal services. The KCC designates universal services and the service provider who is required to provide each service. Currently, we are required to offer free subscription fee and 35% discount of our monthly fee for cellular services to the handicapped and the low-income citizens.

 

In addition to such universal services for the handicapped and low-income citizens, we are also required to make certain monetary contributions to compensate for other service providers’ costs for the universal services. The size of a service provider’s contribution is based on its net annual revenue (calculated pursuant to KCC guidelines which differ from our accounting practices). In 2005, our contribution amount was Won 25.5 billion for our fiscal year 2004. In 2006, our contribution amount was Won 23.7 billion for our fiscal year 2005. In 2007, our contribution amount was Won 23.9 billion for our fiscal year 2006. As a wireless telecommunications services provider, we are not considered a provider of universal telecommunications services and do not receive funds for providing universal service. Other network service providers that do provide universal services make all or a portion of their “contribution” in the form of expenses related to the universal services they provide.

 

Contribution to 114 Directory Service.  Prior to 1998, the cost incurred by KT Corporation to provide 114 directory service was shared among network service providers through the Non-Traffic Sensitive, or NTS, Participation Program. The NTS Participation Program included both the Universal Service Provider Program and contributions for 114 directory services before it came to a halt due to disagreements between the network service providers and the MIC. Since 1999, this cost has been shared among network service providers pursuant to an agreement among themselves. For the period between 2002 and 2004, our share of such costs was determined to be Won 18.3 billion, based on the number of calls made to the 114 directory service through our network. Our contribution amount for 2005 has not yet been determined. Following renegotiation of our agreement with KT Corporation with respect to 114 directory service, beginning in January 2006, we are no longer required to make contributions to the 114 directory service.

 

Foreign Ownership and Investment Restrictions and Requirements

 

Because we are a network service provider, foreign governments, individuals, and entities (including Korean entities that are deemed foreigners, as discussed below) are prohibited from owning more than 49% of our voting stock. Effective from May 9, 2004, Korean entities where a foreign government or a foreigner (together with any of its related parties) is the largest shareholder and owns 15% or more of the outstanding voting stock are deemed foreigners. If this 49% ownership limitation is violated, certain of our foreign shareholders will not be permitted to exercise voting rights in excess of the limitation and the KCC may require other corrective action.

 

As of March 31, 2008, SK Holdings owned 18,748,452 shares of our common stock, or approximately 23.09% of our issued shares. As of March 31, 2008, a foreign investment fund and its related parties collectively held a 4.81% stake in SK Holdings. Effective from May 9, 2004, if the foreign investment fund and its related parties increase their shareholdings in SK Holdings to 15% or more and such foreign investment fund and its related parties

collectively constitute the largest shareholder of SK Holdings, SK Holdings will be considered a foreign shareholder, and its shareholding in us would be included in the calculation of our aggregate foreign shareholding. If SK Holdings’ shareholding in us is included in the calculation of our aggregate foreign shareholding, then our aggregate foreign shareholding, assuming the foreign ownership level as of March 31, 2008 (which we believe was 48.19%), would reach 71.28%, exceeding the 49% ceiling on foreign shareholding.

 

If our aggregate foreign shareholding limit is exceeded, the KCC may issue a corrective order to us, the breaching shareholder (including SK Holdings if the breach is caused by an increase in foreign ownership of SK Holdings) and the foreign investment fund and its related parties who own in the aggregate 15% or more of SK Holdings. Furthermore, SK Holdings may not exercise its voting rights with respect to the shares held in excess of the 49% ceiling, which may result in a change in control of us. In addition, the KCC may refuse to grant us licenses or permits necessary for entering into new telecommunications businesses until our aggregate foreign shareholding is reduced to below 49%. If a corrective order is issued to us by the KCC arising from the violation of the foregoing foreign ownership limit, and we do not comply within the prescribed period under such corrective order, the KCC may

 

 

Additionally, an amendment to the Telecommunications Business Act in May 2004 also authorizes the KCC to assess monetary penalties of up to 0.3% of the purchase price of the shares for each day the corrective order is not complied with, as well as a prison term of up to one year and a penalty of Won 50 million. See “Item 3.D. Risk Factors — If SK Holdings causes us to breach the foreign ownership limitations on shares of our common stock, we may experience a change of control”.

 

We are required under the Foreign Exchange Transaction Act to file a report with a designated foreign exchange bank or with the Ministry of Strategy and Finance, or the MOSF, in connection with any issue of foreign currency denominated securities by us in foreign countries. Issuances of US$30 million or less require the filing of a report with a designated foreign exchange bank, and issuances that are over US$30 million require the filing of a report with the MOSF.

 

A newly adopted amendment to the Telecommunications Business Act effective from May 9, 2004 provides for the creation of a Public Interest Review Committee under the MIC (and, now, the KCC) to review investments in or changes in the control of network services providers. The following events would be subject to review by the Public Interest Review Committee:

 

 

If the Public Interest Review Committee determines that any of the foregoing transactions or events would be detrimental to the public interest, then the KCC may issue orders to stop the transaction, amend any agreements, suspend voting rights, or divest the shares of the relevant network services provider. Additionally, effective from May 9, 2004, if a dominant network services provider (which would currently include us and KT Corporation), together with its specially related persons (as defined under the Korean Securities and Exchange Act) holds more than 5% of the equity of another dominant network services provider, the voting rights on the shares held in excess of the 5% limit may not be exercised.

Patents and Licensed Technology

 

Access to the latest relevant technology is critical to our ability to offer the most advanced wireless services and to design and manufacture competitive products. In addition to active internal and external research and development efforts as described in “Operating and Financial Review and Prospects — Research and Development”, our success depends in part on our ability to obtain patents, licenses and other intellectual property rights covering our products. We own numerous patents and trademarks worldwide, and have applications for patents pending in many countries, including Korea, Japan, China, the United States, and Europe. Our patents are mainly related to CDMA technology and wireless Internet applications. We also acquired a number of patents related to WCDMA technology.

 

We also license a number of patented processes and trademarks under cross-licensing, technical assistance and other agreements. The most important agreement is with Qualcomm Inc. and relates mainly to CDMA applications technology. This agreement generally grants us a non-exclusive license to manufacture handsets in return for royalty payment or a sub-license to manufacture and sell certain products both in Korea and overseas during a fixed, but usually renewable term. We consider our technical assistance and licensing agreements to be important to our business and believe that we will be able to renew this agreement on commercially reasonable terms that will not adversely affect our ability to use the relevant technologies.

 

We are not currently involved in any material litigation regarding patent infringement.

 

Organizational Structure

 

We are a member of the SK Group, based on the definition of “group” under the Fair Trade Act of Korea. As of December 31, 2007, SK Group members owned in aggregate 23.1% of the shares of our issued common stock as of December 31, 2007. The SK Group is a diversified group of companies incorporated in Korea with interests in, among other things, telecommunications, trading, energy, chemicals, engineering and leisure industries. Until mid-1994, our largest shareholder was KT Corporation (formerly known as Korea Telecom Corp.), Korea’s principal fixed-line operator and the parent of KTF, one of our principal wireless competitors.

 

Significant Subsidiaries

 

For information regarding our subsidiaries, see note 2(b) of the notes to our consolidated financial statements.

 

 

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

 

The following table sets forth certain information concerning our principal properties as of December 31, 2007:

 

 

In December 2004, we constructed a new building with an area of approximately 82,624 square feet, of which we have full ownership, for use as our corporate headquarters. We relocated our corporate offices into the new building in January 2005. In addition, we own or lease various locations for cell sites and switching equipment. We do not anticipate that we will encounter material difficulties in meeting our future needs for any existing or prospective leased space for our cell sites. See “Item 4.B. Business Overview — Cellular Services”.

 

In October 2004, we paid Won 30 billion to purchase certain land and buildings (including incidental movables) with an aggregate area of 589,625 square feet from SK Life Insurance Co., Ltd. This property is used as a training facility for our employees.

 

We maintain a range of insurance policies to cover our assets and employees, including our directors and officers. We are insured against business interruption, fire, lightening, flooding, theft, vandalism, public liability and certain other risks that may affect our assets and employees. We believe that the types and amounts of our insurance coverage are in accordance with general business practices in Korea.

 

 

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

 

 

You should read the following discussion together with our consolidated financial statements and the related notes thereto which appear elsewhere in this annual report. We prepare our financial statements in accordance with Korean GAAP, which differs in some respects from U.S. GAAP. Notes 33 and 34 of the notes to our consolidated financial statements provide a description of the significant differences between Korean GAAP and U.S. GAAP as they relate to us and provide a reconciliation to U.S. GAAP of our net income and shareholders’ equity for fiscal years 2005, 2006 and 2007. In addition, you should read carefully the section titled “— Critical Accounting Policies, Estimates and Judgments” as well as note 2 of the notes to our consolidated financial statements which provide summaries of certain critical accounting policies that require our management to make difficult, complex or subjective judgments relating to matters which are highly uncertain and that may have a material impact on our financial conditions and results of operations.
