The following table sets forth information with respect to the average international long distance usage charge per minute that  we received for outgoing international calls during the periods indicated:  Since we offered significant promotional packages and discounts in 2010, the international long distance minutes increased  but total revenue declined, so the average charge  per minute  declined in 2010 compared with that in 2009. We changed our strategy  in 2011 and did not continue to offer aggressive discounts. As a result, the average charge  per minute  increased in 2011 compared  with that in 2010 because the decrease in the international long distance revenues was relatively smaller than the decrease in the  number of minutes. We pay for the use of networks of carriers in foreign destinations for outgoing international calls and receive payments from  foreign carriers for the use of our network for incoming international calls. Traditionally, these payments have been made pursuant  to settlement arrangements under the general auspices of the International Telecommunications Union. Settlement payments are  generally denominated in U.S. dollars and are made on a net basis.  The following table sets forth information with respect to our gross international settlement receipts and payments during the  periods indicated.  Our payments on an aggregate basis to international carriers have been more than our receipts from these carriers primarily  because our customers’ outgoing minutes exceeded incoming minutes.  In order to compete more effectively in the international long distance market, we have implemented innovative and  customized discount calling plans and marketing campaigns directed at high-usage business customers. We also continue to promote  our intelligent network services, including international VPNs, international toll free calling and calling card services, and our  international long distance minutes wholesale business. Our subsidiary, Chief Telecom, launched its 070 phone-to-phone VoIP service  in April 2009. In addition to the change in policy for collecting the tariffs for fixed line-to-mobile calls starting from 2011, we are also  required to pay transition fees to the mobile operators, which as a whole caused negative impact on our revenues. As currently we do  not have the right to set and collect the tariffs for our 070 service, we filed with NCC to return 30 thousand 070 numbers assigned by  the NCC to Chunghwa Telecom, until the NCC give us the right to set and collect the tariffs for outbound calls from 070 numbers.  The application was approved by the NCC on July 1, 2011.  We are a leading provider of international leased line services in Taiwan. Leased line services involve offering exclusive lines  that allow point-to-point connection for voice and data traffic. Leased lines are used by business customers to assemble their own  private networks and by telecommunications service providers to establish networks to offer telecommunications services.
