The Unipetrol Group made a profit exceeding CZK 467m as of March 31, 2003, and the total revenues in the said period exceeded CZK 16.5bn. In the comparable period of the last year, the Group recorded a loss over CZK 196m, whilst having nearly the same revenues (CZK 16.65bn).Among the most significant factors impacting on the results of the Group's companies in the said period belongs particularly international refining margin, which was - as compared with the first three months of the last year - markedly more favourable for the refineries. The increase in the refining margin caused an increase in the price of raw materials for petrochemical production and hence lower margins in the sale of petrochemical products.
