Brazil's state-controlled oil company,
Petroleo Brasileiro SA, said on Monday it adhered to a federal tax refinancing program to settle taxes owed on vessel leasing contracts.
Petrobras, as the company is known, said in a securities filing the company would pay 1.7 billion reais ($538.5 million) in 12 monthly installments beginning this month.
The payments would have a negative effect of 1.1 billion reais on fourth-quarter earnings, the company said.
