(*) Brazilian Law 9,249/95 provides that a company may, at its sole discretion, consider dividends distributions to shareholders to be considered as interest on own capital — subject to specific limitations - which has the effect of a taxable deduction in the determination of income tax and social contribution. The limitation is the greater of (i) shareholders’ equity multiplied by the TJLP (Long Term Interest Rate) rate or (ii) 50% of the net income in the fiscal year. This expense is not recognized for the purpose of preparing the financial statements and therefore does not impact net income.
