O papel de tributos diferidos no capital regulatório de instituições financeiras brasileiras

Abstract

This study sought to provide evidence on the role of deferred tax assets and liabilities as an instrument for the attainment and arbitrage of regulatory capital levels by Brazilian financial institutions in the period from 2004 to 2009. Two hypotheses were developed: the managers of Brazilian financial institutions employ deferred taxes to a) comply with required regulatory capital limits and b) do so in a discretionary manner as a method for regulatory capital arbitrage. The present study collected evidence through the analysis of annual accounting information from Brazilian financial institutions. The hypotheses were tested using multiple linear regression and panel data regression data analysis techniques. The results show that Brazilian financial institutions have used deferred taxes to support or attain the minimum capital levels required by the Basel Accord; however, evidence that the volume of regulatory capital directly influences the volume of deferred taxes was also found, contradicting the international literature, which indicates discretion in the use of deferred taxes as a form of regulatory capital arbitrage.
