Adaro Energy update: Saptaindra Sejati (SIS) ? Mining Contracting

The following is an edited excerpt from IDX-listed energy firm PT. Adaro Energy 's quarterly report released on Monday. (ed)

COAL MINING CONTRACTOR: PT Saptaindra Sejati (SIS)

Our mining and contracting subsidiary, SIS, is one of the five mining contractors we employ at AI. AI is SIS?s largest customer, accounting for 61% and 67% of SIS total overburden removal and coal getting volume during 1Q13, respectively. Lower overburden removal y-o-y and q-o-q was a result of SIS? decision not to extend contracts with two customers, new pit development at AI, and request from customers to reduce stripping ratio. SIS will be the mining contractor that Adaro Energy uses for newly acquired Balangan coal project in South Kalimantan. (end of edited excerpt)
