| 1.1 | The Controlling Company
KT Corporation (the “Controlling Company”) commenced operations on January 1, 1982, when it spun off from the Korea Communications Commission (formerly the Korean Ministry of Information and Communications) to provide telephone services and to engage in the development of advanced communications services under the Act of Telecommunications of Korea. The headquarters are located in Seongnam City, Gyeonggi Province, Republic of Korea, and the address of its registered head office is 90, Buljeong-ro, Bundang-gu, Seongnam City, Gyeonggi Province. On October 1, 1997, upon the announcement of the Government-Investment Enterprises Management Basic Act and the Privatization Law, the Controlling Company became a government-funded institution under the Commercial Code of Korea. On December 23, 1998, the Controlling Company’s shares were listed on the Korea Exchange. On May 29, 1999, the Controlling Company issued 24,282,195 additional shares and issued American Depository Shares (ADS), representing new shares and 20,813,311 government-owned shares, at the New York Stock Exchange. On July 2, 2001, the additional ADS representing 55,502,161 government-owned shares were issued at the New York Stock Exchange.
