In this way, it was decided to adopt the methodology of multiple case study to analyze the motivation of accounting choices for cases identified as exceptional. The results allowed that weighted average cost adoption by companies in general is consistent with the hypothesis of reducing tax burden (tax planning), observed the current economic scenario. For the only company that has adopted the FIFO method, wich belongs the chemical sector, it is observed that the positive accounting theory is not applicable and the Ricardian Principle of Comparative Advantage is the best explanation for the adoption of this accounting method differentiated.
