The CEO of Indonesian energy company Pertamina announced that an outside forensic audit has discovered fraud in its former trading unit, Reuters reports. Indonesia's energy minister says auditors found that third parties had rigged tenders and leaked the Petral unit's price calculations, leading Pertamina to pay higher prices to import fuel and crude oil. Auditors also reported that Petral had prearranged traded volumes to limit competition and given preference to national oil companies. State-owned Pertamina is dismantling Petral, which had been suspected of corruption, and is replacing it with a new group that has yielded US$103 million in cost savings in the third quarter.
