Our ADSL service offers downlink speeds that range from 1 Mbps to 8 Mbps and uplink speeds that range from 64 kilobits  per second to 640 Kbps. Our FTTx service offers downlink speeds of 10, 20, 50 and 100 Mbps matched with uplink speeds of 3, 4,  5 and 10 Mbps, respectively. As of December 31, 2011, approximately 87% of our customers had subscribed for downlink speeds of  over 2 Mbps, and our average downlink speed was 11.2 Mbps. We have experienced competition in the ADSL and FTTx service market from other fixed line operators and cable operators.  Our strategy is to continue the migration of ADSL subscribers to FTTx so as to increase the average revenue per user. In addition,  in order to strengthen customer loyalty, we have provided free speed upgrades for ADSL customers who were using lower speed  services since August 2010. In June 2011, we further reduced our broadband tariff, especially for higher speed services such as 20  Mbps and 50 Mbps, in order to speed up the migration to fiber solutions and facilitate the take-up of relevant applications. Although  the lower broadband tariff had a temporary impact on our revenue, we believe the speed upgrade will have a positive effect on our  promotion of broadband value-added services in the long run. Charges for our HiNet dial-up service include a monthly fee entitling the customer to a fixed number of minutes of service,  with an additional charge per minute when the fixed number of minutes is exceeded. Alternatively, we offer our customers an  unlimited number of minutes for a fixed monthly fee. Charges for our ADSL and FTTx services include one-time installation charges  and monthly subscription fees. These charges for our ADSL and FTTX services vary based on connection speed.  The following table sets forth our average revenue per user for each of the periods indicated.  The decline of our ADSL average revenue per user over the last three years was due to the National Communications  Commission mandated tariff reduction and the decline of FTTx average revenue per user was due to the promotional packages  and discounts provided for existing customers. However, we expect our average revenue per user for broadband services to remain  stable going forward as many customers will continue to migrate towards more expensive and higher speed FTTx services which  will offset the declining average revenue per user of ADSL and FTTx themselves.
