The year-on-year increase was caused by higher oil and oil product prices, associated with lower exploration costs in Turkey, Argentina and the USA, as well as the incorporation of Nigerian production, the acquisition of the Okinawa refinery and the improved contractual conditions in Bolivia as of May 2007.
These effects were partially offset by i) lower sales margin and volume in the USA (R$ 516 million); ii) the constitution of provisions for royalty contingencies. (R$ 173 million); iii) provisions for the reduction of inventories to market value (R$ 96 million); iv) lower capital gains as a result of the sale of companies in Bolivia and Argentina in 2007 (R$ 88 million).
The quarter-on-quarter downturn was due to:
Lower oil sales margins in Argentina and lower oil product sales margins in the USA;
These effects were offset by the impact of the depreciation of the Real against the dollar on the conversion of accounting statements.
