Valor de mercado e disclosure voluntário: estudo empírico em companhias listadas na BM&FBOVESPA

Abstract

This study examined the relationship between the market value (measured by Tobin's Q) and voluntary disclosure economic, social and environmental sustainability reports of companies listed on the BM&FBovespa. We analyzed the Standardized Financial Statements (SFS), Annual Reports (AR) and Sustainability Reports (SR) in the period from 2007 to 2011. The results indicate the existence of significant and positive relationship between voluntary disclosure economic and market value of companies, the same is not true with regard to voluntary disclosure environment that has a significant relationship, but negative in relation to Tobin's Q, demonstrating a trade vision-off between the investor and the manager, as such disclosure is strategically important from the viewpoint of business management. No evidence of a significant relationship between social voluntary disclosure and market value of companies. The study could help to encourage companies to voluntarily disclose information of an economic, social and environmental both quantitative and qualitative, as a strategic, yet aligned their mission and values as a way to communicate with their stakeholders and through that channel as to obtain benefits efficiency in management and business continuity expectations, given the enforcement of regulatory bodies, society and other agents that interfere in business and have direct legitimate. This incentive represents compensatory and contingency measures can reduce risks and transmit corporate responsibility and follow a global trend, which considers factors involving actions of a social and environmental function as extensions of social enterprises
