The purpose of this paper is to provide empirical evidence of the quantitative impact of the differences between Portuguese accounting rules and IFRS, by analysing total and individual adjustments to IFRS in the reconciliations of equity and net income of all Portuguese listed companies. The empirical results indicate a more relevant total impact of such a transition on net income than equity. 2
