- Estimated losses: $2 billion so far
Brazil's state-owned oil giant Petrobras (PBR) has been entangled in a sprawling corruption scandal for months.
Prosecutors have accused former executives of illegally "diverting" billions from its accounts for their personal use, or to pay off officials.
More than 80 people, including senior politicians, have been charged with bribery and money laundering during the criminal investigation, dubbed "Operation Car Wash."
