We provide data transmission services to major corporate customers in Taiwan. Since August 2001, licenses have been awarded to four undersea cable operators to engage in leased line services. Demand for high-speed data transmission services has been growing rapidly, as a result of growing consumer demand and lower tariffs due to increased competition. In particular, the total bandwidth of our lines leased increased by 115% in 2011. 

The following table shows the bandwidth of international lines leased to third parties as of each of the dates indicated.

Rental fees for international long distance leased line 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. 

## International Data Services 

Our international data services include international IP VPN services and Taiwan internet gateway services. Total revenues for international data services were NT$0.8 billion, NT$1.0 billion and NT$1.1 billion (US$37.4 million) for 2009, 2010 and 2011 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. 

## Satellite Services 

We 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$198.2 million). This contract requires a prepayment of NT $3.1 billion (US$101.4 million), and the remaining amount will be paid annually when ST-2 satellite starts its official operation. The ST-2 telecommunications satellite launched on May 21, 2011 and began commercial operation in August 2011. We stopped commercial operation of the ST-1 telecommunications satellite at the end of 2011 when the ST-2 satellite began commercial operations. Please refer to note 29 of our consolidated financial statements included elsewhere in this annual report for further details. 

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.
