International Data Services  Satellite Services  International Other Services  Others  Interconnection  PART I As of December 31, 2008 2009 2010 (in gigabits per second, or Gbps) Total bandwidth 43.3  63.1  113.4  Rental fees for international long distance leased line rental fees are generally based on transmission speed  and distance.  We continue to experience a decline in rental fees for all of our leased line products. The decline in rental  fees since 2000 has been substantial, particularly for international leased lines, partly as a result of competition  from new international leased line service providers. In response, we continue to implement marketing and  service campaigns to retain our high-value corporate customers.  Our international data services include international IP VPN services and Taiwan internet gateway services.  Total revenues for international data services were NT$0.7 billion, NT$0.8 billion and NT$1.0 billion (US$35.8  million) for 2008, 2009, 2010 respectively. Due to growth of the international corporations in Taiwan, we expect  demand for IP VPN and Taiwan internet gateway services to continue to increase and our revenues from our  international data services to continue to grow.  We are a 50% owner of the ST-1 telecommunications satellite. Singapore Telecommunications Ltd. owns  the remaining 50%. ST-1 was launched on August 26, 1998 and began commercial operations on December 1,  1998. We lease out transponder capacity on ST-1 and provide satellite lease circuits. In addition, we have two  satellite communication centers that enable us to provide satellite value-added services and backup systems for  use in major emergencies. We also provide satellite services to Southeast Asia. We are currently constructing  the ST-2 telecommunications satellite together with Singapore Telecommunications Ltd. and plan to launch this  satellite by the second quarter of 2011. We expect to retire the ST-1 telecommunications satellite after the launch  of the ST-2 telecommunications satellite.  Chunghwa entered into a contract with ST-2 Satellite Ventures Pte., Ltd. on March 12, 2010 to lease  capacity on the ST-2 satellite. The lease term is 15 years starting from the official start of operations of the ST-2  satellite, and the total contract value is approximately NT$6.0 billion (US$187.8 million). We have already  prepaid NT$2.5 billion (US$86.4 million), which was classified as other assets – others. As of December 31,  2010, the ST-2 satellite is still under construction.  Our international other services include corporate solution service.  Our others business segment include revenues from our non-telecom services, including our educational  training programs and technology transfer income.  We provide interconnection of our fixed line network with other mobile operators and, since July 2001, with  other fixed line operators.  38
