Mattos Filho provided a comprehensive review of the bidding process, tender rules, and regulatory framework for Brazil’s production-sharing regime through a due diligence report. We also provided support on several practical matters related to the bid and the internalization of documents required for qualification, as well as in interactions with ANP. Additionally, we accompanied the client during the public tender session at ANP.
