The central objective of this paper is to identify the factors that explain the level of voluntary disclosure of Brazilian public companies. The theory underpinning this work is the Discretionary-based Disclosure (Verrecchia, 2001). Sample is composed by the top 100 largest non-financial public companies listed in Bovespa. Information has been gathered from Financial Statements for the years ended in 2006, 2007 and 2008 with the use of content analysis. For these, a disclosure framework based on 27 studies has been elaborated. This framework contains a total of 92 voluntary items, divided in two dimensions: economic (43), social-environmental (49). Based on the existing literature, a total of 12 hypotheses have been elaborated and tested using a panel data approach. We have also analyzed the association between voluntary disclosure and company’s sector, which has been confirmed by the Chi-square test at a significance level of 1%. Correspondence Analysis, by means of the perceptual map, has evidenced that (i) retail sector is associated with a ‘bad’ level of disclosure and (ii) electric sector is associated with a ‘good’ and ‘great’ level of voluntary disclosure. Panel data analysis has evidence that: (i) ‘Sector’ and ‘Origin of Control’ are statically significant in all three models tested: economic, social-environmental, and total; (ii) ‘Profitability’ is relevant in the economic model and in the total model; (iii) Tobin’s Q is relevant in the social-environmental model and in the total disclosure model, (iv) ‘Leverage’ and ‘Auditing Firm’ are relevant, only, in the economic disclosure model; (v) ‘Size’, ‘Governance’, ‘Stock Issuing’, ‘Growth Opportunities’ and ‘Concentration of Control’ are not statistically significant in any of the three models of disclosure.
