30. TARIFF SYSTEM

In January 2007, the government implemented Decree No.08PERM.KOMINFO022006 of the Minister of Communication and Information Technology regarding Interconnection. By this Decree, a tariff system was implemented based on KM No. 09PERM.KOMINFO042008 regarding Terms and Conditions for Rate Determination of the Cellular Mobile Network Telecommunications Service, which has applied to all operators since 7 April 2008. Based on KM No. 09PERM.KOMINFO042008 the tariff structure is as follows:  Activation fees  Monthly charges  Usage charges  Value added service charges The calculation tariff formula for a postpaid or prepaid subscriber is based on the decree using the folowing formula: Retail tariff = Network Element Cost + Retail Activation Cost + Profit Margin Notes: a. Network element cost is calculated using the Long Run Incremental Cost “LRIC” Bottom Up method as stated in Decree No.08PERM.KOMINFO022006 of the Minister of Communication and Information Technology regarding Interconnection. b. Activation cost is calculated using retail activation cost. The cost is distributed to all subscribers with the following formula: Activation cost = Total activation cost Projected subscribers number Note: Total activation cost = Total activation cost of basic telephony service c. Profit margin is income used by the Company to calculate the tariff. Interconnection Tariff The Company entered into several bilateral agreements with other domestic telecommunications operators regarding interconnection tariff sharing for each interconnection call. These agreements are in accordance with the prevailing regulations. Based on Decree No.08PERM.KOMINFO022006 of the Minister of Communication and Information Technology dated 8 February 2006, the interconnection tariff will be charged based on cost, which is offered in the Documents of Interconnection Offer from each operator and effective from the date the Decree was signed. All operators have to apply a cost allocation principle in calculating the interconnection cost as soon as this is approved by the government. During the transition period, bilateral interconnection agreements are technically still valid as long as they are approved by both parties and aligned with this Decree. Since 1 January 2007, the Regulation has applied to all operators. On 5 February 2008, Badan Regulasi Telekomunikasi Indonesia “BRTI” announced that the new interconnection tariff must be implemented by 1 April 2008 at the latest.
