Mandatory IFRS adoption in Brazil and firm value

Using diff-in-diff approaches and the propensity-score matching, this study focuses on firm-level Tobin´s q and Market-to-book outcomes for Brazilian firms who in 2008 were required by Law 11.638/07 to adopt the full International Financial Reporting Standards (IFRS) by 2010. Brazil’s tier-system of corporate governance standards for publicly-traded firms, its uniquely wholesale adoption of the IFRS, and the previously considerable gap between its national GAAP and IFRS readily lend the scenario to research, which thus far finds small or inconsistent results when focused on IFRS adoption-related outcomes in Europe and China. However, while these features recommend the transitioned Brazilian equity market to analysis, additional unique features, such as its small population size and its limited historical data -- of varied quality – increase the challenge in selecting a suitable empirical methodology. Using quarterly data from 2006-2011, control firms in the Nivel II and Novo Mercado tiers of Bovespa which already complied with higher quality accounting standards are matched to treatment firms in the Regular and Nivel I tiers with similar averaged values of size and sector. Our results suggest that there is a positive impact on Tobin´s q and Market-to-book for firms who are forced to adopt IFRS in Brazil. We can observe the same results when we consider all variables winsorized at 5% level. We also find a positive relation between the firm value (measured by Tobin´s q and Market-to-book) and net income. Firms with higher net income are more likely to have higher Tobin´s q and Market-tobook. In an opposite way, we find a negative relation among firm value, size, Ebit-to-sales, sales growth and PPE-to-sales. All results are statistically significant at 1% level.
