Our revenues increased by 7.4% from NT$202.4 billion in 2010 to NT$217.5 billion (US$7.2 billion) in 2011. This increase  was primarily due to increase in revenues generated from domestic fixed communications, mobile communications, and other  business sectors.  Domestic fixed communications revenues comprised 34.9% and 36.5% of our revenues in 2010 and 2011, respectively. Our  domestic fixed line revenues increased by 12.3% from NT$70.7 billion in 2010 to NT$79.4 (US$2.6 billion) in 2011.  Local telephone services.  Our local telephone revenues increased from NT$32.3 billion in 2010 to NT$41.7 billion (US$1.4  billion) in 2011. This reflects the shift in policies for collecting the tariffs for fixed-to-mobile calls from mobile service providers to  fixed communications service providers since January 1, 2011, which gave our fixed communications business the right to set and  collect the tariffs for fixed line-to-mobile phone calls. Traffic volume increased from 13.7 billion minutes in 2010 to 15.6 billion  minutes in 2011. We primarily attribute the increase in traffic volume to the inclusion of fixed-line to mobile calls under this category  as a result of the NCC’s change in policy for collecting the tariffs from fixed-line to mobile calls starting from 2011. For the same  reason, our local interconnection revenues decreased by NT$1.0 billion from NT$2.4 billion in 2010 to NT$1.4 billion (US$0.05  billion) in 2011 because fixed communications service providers received less interconnection charges from mobile service providers.  Domestic long distance telephone services.  Our domestic long distance telephone revenues decreased by 12.9% from NT$6.6  billion in 2010 to NT$5.8 billion (US$0.2 billion) in 2011. This decrease was mainly due to a decrease in traffic volume from 3.4  billion minutes in 2010 to 3.2 billion minutes in 2011. The decrease in traffic volume was primarily due to the continued traffic  migration from fixed line services to mobile services and VoIP.  Broadband access.  The number of our ADSL customers decreased from 2.3 million in 2010 to 2.1 million in 2011 due to  customer migration to our FTTx services. There was an increase in the number of FTTx customers from approximately 2.0 million in  2010 to approximately 2.4 million in 2011. Broadband access revenue increased from NT$20.3 billion for 2010 to NT$20.4 billion  (US$0.7 billion) for 2011.  Domestic leased line.  While demand for higher speed leased lines continues to increase, our overall leased line tariffs have  continued to be adversely affected by competition from other fixed line operators, as well as the continued migration of domestic  leased line customers to broadband services. Domestic leased line revenue decreased from NT$6.1 billion for 2010 to NT$5.7 billion  (US$0.2 billion) for 2011.  MOD.  Our MOD revenues increased by 31.2% from NT$1.1 billion in 2010 to NT$1.4 billion (US$0.05 billion) in 2011.  This increase was mainly due to an increase in the number of subscribers. Others.  Other revenues increased by 0.4% from NT$4.3 billion in 2010 to NT$4.4 billion (US$0.1 billion) in 2011. This  increase was mainly due to an increase in corporate solution ICT business. Revenues from our mobile communications business segment comprised 44.0% and 42.8% of our revenues in 2010 and  2011, respectively. Revenues from our mobile communications business segment increased by 4.4 % from NT$89.0 billion in 2010 to  NT$93.0 billion (US$3.1 billion) in 2011. This increase was principally due to the growth of mobile VAS revenue and handset sales  revenue offsetting the decline of mobile voice revenue since 2008. The growth of mobile voice traffic due to the general recovery  of the economy in the R.O.C. was partially offset by the mandatory tariff reduction and the impact from the change in policy for  Mobile communications  Domestic fixed communications  P AR T I Revenues  The year ended December 31, 2011 compared with the year ended December 31, 2010  76
