August 2019 – Certificate valid until 2024

Oi’s Internal Audit team has the Quality Certificate from Brazil’s Internal Auditors Institute. This recognizes that Oi’s Internal Audit complies with international standards, adds value to the company, contributes to achieving the goals and provides quality gains to improve the internal control environment. In Brazil, only 19 companies have this certification. As the certification is valid for five years, we underwent a new assessment in the second half of 2020. This new recognition is valid until 2024.
