In this scenario, the simplest way to measure our financial impacts on the locations where we operate is based on the payment of royalty payments we make to the federative entities. The royalties represent the financial compensation owed to the federal government, the states, and the beneficiary municipalities by the companies that produce oil and natural gas in Brazilian territory: a compensation to society for the exploitation of these non-renewable resources. In practice, they are levied on the value of the field production at rates that vary from 5% to 10%. All of our producing fields pay 10% of production in royalties, with the exception of Azulão, whose rate is 5.6%. The royalties are supervised by the ANP, which is also responsible for the distribution of this government participation to the federative entities. The Agency recently improved the dissemination of royalty distribution amounts, making it easier to consult this data. For this reason, unlike the methodology adopted in 2019 and 2020 - when the royalty data presented in the Sustainability Report were estimated (subtly different from the database published by the ANP) for this Report we used the official information published by the ANP itself. That said, totaling the sums of the Federal Government, states and municipalities, we paid R$ 196,111,969.27 in royalties over 2021, being directly responsible forthe compensation of R$41,594,878.57 to the municipalities of Maranhão and R$ 828,620.17 to the municipalities of Amazonas. In detail, it is possible to divide the royalty compensation paid to the producing municipalities in 2021 as follows: > Trizidela do Vale (MA) > Lima Campos (MA) R$ 10,558,649.79 > Sto. Antônio dos Lopes (MA) R$ 11,217,289.50 R$ 7,786,380.57 R$ 6,291,962.46 > Capinzal do Norte (MA) R$ 5,399,423.04 > Bernardo do Mearim (MA) R$ 297,832.93 > Pedreiras (MA) > Fortuna (MA) > Silves (AM) > Itapiranga (AM) Production participation for the owners of the land where the producing wells are located In 2021, in compliance with the provisions of Decree 2.705/1998, Art. 3, Item VIII and in the concession contracts signed with the Federal Government, we paid R$ 19,394,614.35 to these owners as a share in production.
