is still state-owned today and the official postal carrier for Indonesia's 230 million people. In 1974, PN Telekomunikasi was further divided into two state-owned companies. Perusahaan Umum Telekomunikasi (Perumtel) provided domestic and international telecommunications services, while PT Industri Telekomunikasi Indonesia (PT INTI) manufactured telecommunications equipment. A further division in 1980 saw the international telecommunications business taken over by the newly nationalized PT Indonesian Satellite Corporation (Indosat). In 1991, Perumtel became a state-owned limited liability corporation and renamed to what is now Perusahaan Perseroan (Persero) PT Telekomunikasi Indonesia or Telkom. Until 1995, Telkom's operations were organized along twelve regional operating units known as Wilayah Telekomunikasi or Witel. Each Witel had full responsibility for all aspects of business and operations in their respective regions, such as telephone services, property management, and security. In 1995, Telkom reorganized the twelve Witels into seven regional divisions and one network division. Under a series of Cooperation (KSO) Agreements, Telkom transferred the right to operate five of its seven regional divisions (I, III, IV, VI, and VII) to private sector consortia. Under these agreements, the KSO partners manage and operate the regional division concerned for a fixed term, build a specified number of fixed lines which at the end of the term, transfer the telecommunications facilities to Telkom for an agreed amount in compensation. Revenues from the KSO operations were shared between Telkom and the KSO partners. Privatization On 14 November 1995, Telkom became a privatized company when shares went on sale through an Initial public offering on the Jakarta Stock Exchange and the Surabaya Stock Exchange (which merged in December 2007 to become the Indonesia Stock Exchange). Telkom's shares are also listed on the NYSE and the LSE in the form of American depositary shares (ADSs), and were publicly offered without listing on the Tokyo Stock Exchange. Telkom is now the largest company by market capitalization in Indonesia, with a market capitalization of approximately IDR 190,512 trillion as of 31 December 2009. The Government retains an aggregate interest of 51.19% of the issued and outstanding shares of Telkom. The Government also holds one Dwiwarna, or golden share. In mid-1997, Indonesia was badly affected by the Asian economic crisis. Among those impacted were certain KSO partners, who experienced difficulties in fulfilling their obligations to Telkom. Telkom eventually acquired control of its KSO partners in Regions I, III, and VI, and amended the terms of the KSO agreements
