In exchange for bribes OAS reportedly was able to get beneficial contracts from Petrobras state-controlled oil company.
In 2014, it was revealed that businesses paid more than $2 billion in bribes to sign contracts with the oil company and obtain projects which later increased in cost. The scandal triggered a large-scale inquiry and discontent which were partly responsible for the impeachment of Brazilian President Dilma Rousseff who headed the company in 2003-2010.
Lula da Silva has been also banned from occupying any official positions for 19 years, which undermines his plans to run for presidency in 2018, and has been fined $205,000. The former president is reportedly going to appeal to the court's decision.
