PART I 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 partly as a result of broadband services substitution and other service  providers constructing their own lines. In response, we continue to implement marketing and service campaigns  to retain our high-value corporate customers.  We launched our wireless local area network service in May 2002. As of December 31, 2010, we had a total  of approximately 63,577 residential and business customers that lease our access points. In addition, we have  established 10,146 hot spots in public areas, such as convenience stores, airports and international convention  centers, where individuals can access our wireless local area network.  We launched our multimedia-on-demand, or MOD, service in Taipei County and Keelung City in March  2004. As of December 31, 2010, we have expanded this service to all 18 counties and cities of Taiwan. Using  video streaming technology through a set top box that connects to our FTTx and ADSL data connections, our  customers can access TV programs and other services. We had over 126 broadcasting channels and over 8,000  hours worth of on-demand programs and served approximately 0.8 million customers as of December 31, 2010.  In addition, our video-on-demand service provides movies, dramas, animations, documentaries, e-learning  and music programs for home entertainment. Also, we currently offer 16 high definition, or HD, channels and  other HD video-on-demand programming, such as sports, movies and knowledge materials. We offered “family  package” channels in 2010 to enhance our service content and satisfy our customers’ needs.

Our domestic other services include information and communication technology services, corporate  solution and bill handling services.
