The vice-governor of BNA said he sent an e-mail to Valter Filipe in August 2017 specifying his position on the agreement with Mais Financial Services, but that the answer never came. He also said that whenever the former governor of BNA spoke on the matter, he made it clear that he was against signing the agreement.
During the session, Tiago Dias said that Valter Filipe asked him to do a study on the diversification of the economy in the country. The vice-president of the BNA asked for help from experts in economics and, after interpreting the results, it seemed wiser to him to issue an opinion: "We found that Mais Financial Services had no references to carry out the work it was proposing.
Tiago Dias also revealed that in October 2017 - when the 500 million dollars had already been transferred to London - Valter Filipe asked him again for the study. The vice-governor of the BNA forwarded the opinion again to the former governor of the BNA, but the reaction was not very positive: the former governor of the bank said he was not waiting for the opinion, but for the study and advised him to ask for help from António Ebo, his former economic advisor, and António Samalia Bule, former director of the BNA's Reserve Management Department.
Valter Filipe said that the study was part of the first contract signed with Mais Financial Services and rejected having received the e-mail from Tiago Dias: "I have never seen this opinion and have not had contact with it".
The former governor of BNA also said that the opinion had been sent to his professional e-mail and that as he was in London he did not see it because he did not have access to the bank's internal communication tools.
Tiago Dias again contradicted the defendant, stating that the members of the Board of Directors, even when they are outside the country, have access to their professional e-mails.
