Abstract: This study estimated the quality of governance practiced by a significant sample of Brazilian publicly traded companies and a sub sample of Brazilian energy companies, between 2002 and 2006, and related it to risk. An index composed of 20 questions, with all answers in binary form, was constructed to measure the quality of governance. The results obtained through the application of the method of simple and multiple linear regressions, were confirmed, with robustness, by the results obtained by the use of structural equations, confirming the original hypotheses. The effects of possible endogeneity do not harm the results obtained using the linear regressions. In this initial approach it seems that governance is relevant for the sample and sub sample of energy companies, though we did not observe significant statistical results for the sub sample of energy companies.
