Rolls-Royce has agreed in principle to settle bribery and corruption cases with U.S., U.K. and Brazilian authorities by paying the equivalent of more than $800 million to the three countries, the company said in a news release Monday. Rolls-Royce said it has cooperated with authorities on the cases, which involve bribery and corruption of intermediaries in overseas markets, concerns about which the company said it passed to the SFO from 2012 onwards.
