Bloomberg News reported Wednesday that the six biggest U.S. banks have spent $103 billion in legal fees since the financial crisis, more than they have paid in dividends.
Bloomberg noted that about 40 percent of those expenses have come up since the beginning of 2012.
JPMorgan also reportedly is in talks with a group of regulators, including U.S. prosecutors, to settle probes of the bank's "London Whale" trading losses last year for about $600 million, according to a person familiar with the talks.
Regulators, including the U.S. Securities and Exchange Commission and the UK Financial Conduct Authority, are in intense negotiations with lawyers for JPMorgan to reach a global settlement, the source told Reuters.
Prosecutors from U.S. Attorney Preet Bharara's office were also involved in the talks, the source said. Their role in the talks was unclear.
