SingTel, Asia's leading communications group, is reaping the benefits of an international expansion strategy which has been successfully developed over the last 15 years. With significant operations in Singapore and Australia (through wholly-owned subsidiary SingTel Optus), the Group provides a comprehensive portfolio of services that include voice and data services over fixed, wireless and Internet platforms. SingTel Optus is a leading Australian integrated communications company. Since commencing operations in 1992, Optus has invested more than A$7 billion in the construction of fixed, mobile and satellite networks. Optus' mobile business unit has captured around one third of the total Australian GSM mobile market. SingTel is also a strategic investor in four of the region's most successful mobile operations. It has a 21.42 per cent stake in Advanced Info Service (AIS), Thailand's largest mobile operator. In India, the Group has a 30.51 per cent effective interest in Bharti Tele-Ventures, the country's largest GSM operator. One of SingTel's earliest investments in the region is Globe Telecom in the Philippines. Today, it has a 44.61 per cent stake in the company. SingTel has a 35 per cent stake in Indonesia's largest mobile operator, Telkomsel. It also has a 45 per cent equity stake in Pacific Bangladesh Telecom Limited (PBTL). The SingTel Group had a turnover of S$12.62 billion (US$7.65 billion) and net profit after tax of S$3.27 billion (US$1.98 billion) for the year ended 31 March 2005. For the year, AIS, Bharti, Globe and Telkomsel contributed S$1.19 billion in pre-tax earnings (excluding exceptional items) to the Group. The four associates also contributed S$303.
