The pro forma statements above mentioned were prepared considering all lines of the income statement, including 100% of Itaú CorpBanca’s result. The result related to the minority shareholders is shown in the “minority interests in subsidiaries” line, for both CorpBanca and Itaú Chile.

Payout Practice In order to manage capital efficiently, aiming at creating value to our shareholders, we announced through a Material Fact disclosed on September 26, 2017, that we intend to: Maintain the practice of paying dividends and interest on own capital at 35% of net income, however we excluded the maximum limit previously determined at 45%. Set forth, through the Board of Directors, the total amount to be distributed each year considering: • the company’s capitalization level, according to rules issued by the Brazilian Central Bank; • the minimum Tier 1 Capital* of 13.5% determined by the Board of Directors. We highlight that this ratio must be composed of at least 12% of Core Capital; • the profitability in the year; • the expectations of capital use based on the expected business growth, share buyback programs, mergers and acquisitions and regulatory changes that may change capital requirement; • changes in tax legislation. Therefore, the percentage to be distributed may change every year based on the company’s profitability and capital demands, always considering the minimum distribution set forth in the Bylaws. * Taking into consideration the full application of Basel III rules, in addition to the impact from the acquisition of the minority interest of 49.9% in XP Investimentos.
