The following table sets forth our interconnection fee revenues and costs for the periods indicated. These revenues and costs  are included, depending on the nature of the call made, in domestic fixed communications or mobile communications revenues and  expenses, respectively.  (1)  Includes local and domestic long distance telephone services. (2)  Includes SMS air time charges.  (3)  The interconnection costs increased in 2011 due to the change in policy for collecting the tariffs for fixed line-to-mobile calls  starting from 2011. Tariffs for telephone calls between our fixed line customers and mobile customers of other mobile operators were set by the  mobile operators before January 1, 2011. The mobile operators pay us interconnection fees based on minutes of usage, regardless of  who initiated the call. However, the National Communications Commission made amendments on August 4, 2010, stipulating the  fixed line network that initiated the call has the right to set and collect the tariffs for these fixed-line to mobile calls from January 1,  2011 onwards. Since we are the market leader of the local call services, in addition to the interconnection fees, we are also required to  pay transition fees to the mobile operators for a period of six years. The transition fees will decrease gradually over the period and we  will stop paying for them in 2017. The foregoing reasons caused the increase in our interconnection costs in 2011. The interconnection rate for calls initiated by mobile customers to fixed line customers is NT$0.5219 per minute during peak  times and NT$0.2718 per minute during off-peak times. The interconnection rate between fixed line customers and other fixed line  customers is NT$0.32 per minute during peak times and NT$0.09 per minute during off-peak times. The interconnection rate for  fixed line customers to domestic or international long distance is NT$0.32 per minute.  In accordance with governmental regulations, the contracts governing our interconnection arrangements must specifically  address a number of prescribed issues. For example, our interconnection charge should reflect our costs with respect to the network  elements used. In addition, cost increases are subject to approval by the regulatory authorities. We expect that our interconnection  contracts will generally be reviewed annually, although we may also enter into long-term contracts.  Our ICT services includes integrated services such as our Intelligent Energy Network, or iEN, and our Intelligent  Transportation System, or ITS, services. Our iEN service helps companies and corporations implement energy saving measures  through computer analysis of data. Our ITS service provides navigation, real-time traffic information and infotainment through  mobile devices for cars and drivers. In addition to developing ICT businesses, such as iEN, ITS, IS, Call Center, IDC, we also pursue  and bid for government projects aiming to boost economic development, for example, we had won the bid for “The New Generation  Reform Project of Taxation Information Systems” launched by the Financial Data Center, Ministry of Finance in February 2010,  “Mobile Police (M-Police) Project”, “Backbone Network and Backup Service Project” for Air Navigation & Weather Services, Civil  Aeronautics Administration, and “Broadband Network Installation Project” for monitoring equipment of Suhua Highway in 2011.  40 Emerging Services P AR T I Year Ended December 31, 2009 2010 2011 NT$ NT$ NT$ US$ (in billions) (in millions) Interconnection fee revenues: Fixed line  (1) 2.9 2.7 1.6 50.5 Mobile  (2) 7.5 7.9 8.3 273.8 Interconnection costs: Fixed line (1)(3) 0.2 0.2 5.9 196.7 Mobile 7.2 7.4 8.4 277.0
