From Bloomberg, dateline 2010-10-12:
Petroliam Nasional Bhd., Malaysia’s state oil and gas company, increased a price-adjustment factor for its benchmark Tapis crude to a record for a second month.
Petronas, as the Kuala Lumpur-based company is known, raised the factor to $4.20 a barrel for October, up 10 cents from September, said an official today, asking not to be identified because of corporate policy. Last year, the adjustment factor averaged $2.48.
The increase follows a recovery in profit for turning light crude such as Tapis into gasoil, or diesel. The product’s premium to Dubai crude, the Asian benchmark, ended September trading at $11.97 a barrel, the first monthly gain in three, according to brokers PVM Oil Associates. This crack spread climbed to $13.38 today, the highest since Aug. 3.
Petronas includes the Tapis adjustment factor in its formula for calculating monthly crude official selling prices. The other component is the average of twice-weekly assessments compiled by the Asian Petroleum Price Index, a Hong Kong-based panel of traders.
