The reduction in the quarter-over-quarter result was due to the following factors:
The increase in oil acquisition/transfer costs and imported oil product costs, reflecting the reduction in oil prices; and
The reduction in average domestic oil product prices due to the downturn in diesel and gasoline prices in June 2009.
These factors were partially offset by:
Higher oil product sales volume in Brazil;
Higher average export prices and, in Brazil, an increase in the price of those oil products pegged to international prices; and
The sale, in the 3Q-2009, of inventories formed in the previous quarter at a lower acquisition cost.

Excluding the impact of the depreciation of the Real, corporate overhead fell by 1% over the 1H-2008 due to reduced expenses from sponsorships and advertising, partially offset by the upturn in data-processing and personnel expenses.
Discounting the appreciation of the Real, corporate overhead increased by 8% over the previous quarter, due to higher data-processing, sponsorship and personnel expenses.
