A unit of RBS, possibly in Asia, is likely to plead guilty to manipulating the London interbank offered rate (LIBOR). A settlement with U.S. prosecutors is likely by mid-Feb. 2013. A penalty of 500 million pounds or $790 million is expected as part of a legal settlement, according to people briefed on negotiations. RBS is 82% owned by the British government. This follows legal settlements totalling about $2 billion with Barclays and UBS. Banks are also concerned about the risks of private litigation. Deutsche Bank is being investigated for its involvement.
