(1) Includes foreign units ex-Latin America; (2) Includes financial guarantees provided and corporate securities; (3) Composed of Result from loan losses, Impairment and discounts granted; (4) Commissions and fees (+) income from insurance, pension plan and premium bonds operations (-) claim expenses (-) insurance, pension plan and premium bonds selling expenses. On November 04, 2019, we announced the results for the third quarter of 2019 and informed that we have maintained our projection intervals for 2019 unchanged. Below, the company sets out the baseline scenario for each line. The total credit portfolio in Brazil should end the year around the top of the projection interval, due to an acceleration on the demand for credit from individuals, very small, small and middle market enterprises. Consequently, the consolidated credit portfolio should be around the midpoint of the interval. The forecast of a lower Selic rate and a narrower future yield curve have a negative impact in the expectations for our liabilities margin and for our working capital NII. Therefore we anticipate our financial margin with clients to finish the year close to the lower end of the projection. We expect our financial margin with the market to be around the midpoint of the range. Our expectation is to finish the year with a cost of credit between the midpoint and the top of the interval, due to the increase in our expectation for expansion of the loan portfolio in Brazil, sustained by an acceleration on the demand for credit from individuals, very small, small and middle market enterprises. As for the commissions and fees line we anticipate to finish the year between the mid and lower point of the projection. Finally, we expect our non-interest expenses to finish the year around the lower end of the projection. It is noteworthy mentioning that the Company currently includes, for business management purposes, cost of capital of approximately 12.5% per year. 12.12 – Other Relevant Information – Addition Information of items 12.5/6 and 12.7/8 A - Total Number of Meetings Held by Body: Body Meetings (1) Board of Directors 6 (1) Fiscal Council 2 (2) Audit Committee 34 (3) Disclosure and Trading Committee 4 (2) Strategy Committee 4 (2) Capital and Risk Management Committee 7 (2) Nomination and Corporate Governance Committee 3 (2) Related Parties Committee 9 (2) Personnel Committee 3 (2) Compensation Committee 3 (4) Social Responsibility Committee 0 (1) from October 24, 2018 to February 22, 2019 (2) from June 25, 2018 to Februaryy 22, 2019 (3) from April 19, 2018 to January 21, 2019 (4) Social Responsibility Committee, formed on January 31, 2019 (1) Includes foreign units ex-Latin America; (2) Includes financial guarantees provided and corporate securities; (3) Composed of Result from loan losses, Impairment and discounts granted; (4) Commissions and fees (+) income from insurance, pension plan and premium bonds operations (-) claim expenses (-) insurance, pension plan and premium bonds selling expenses.
