The higher result was caused by the 6% increase in sales margins and the 9% upturn in sales volume.
The segment recorded a 38.8% share of the fuel distribution market in the 3Q-2009, versus 38.0% in the previous quarter.
The main events impacting the year-on-year reduction were:
The reduction in gross profit due to lower international oil prices; and
Lower equity income due to losses on investments in the USA from the acquisition of the remaining 50% of the Pasadena refinery.
This excerpt taken from the PBR 6-K filed Aug 18, 2009.
The quarter-over-quarter results increase was due to the upturn in international oil prices and the increase of 7% in the oil sale/transfer volume, as well as the reduction in exploration costs due to the write-off of dry or economically unviable wells.
These factors were partially offset by the higher government take and increased geological and geophysical costs
The spread between the average domestic oil sale/transfer price and the average Brent price fell from US$ 12.17/bbl in the 1Q-2009 to US$ 10.11/bbl in the 2Q-2009.
The year-on-year improvement in the Supply result was due to lower oil acquisition/transfer costs and reduced imported oil product costs, reflecting the new level of international oil prices.
These effects were partially offset by the following factors:
The reduction in average oil product prices due to reduced export prices and, in Brazil, to the lower price of those oil products pegged to international prices; gasoline and diesel prices remained at 2008 levels until June 2009;
Higher operating expenses, particularly from the adjustment of inventories to market value and from judicial contingencies.
