Regulators in the US and UK are expected to fine JP Morgan Chase more than $900 million for actions tied to its 2012 "London " trading debacle, according to a person familiar with the settlement talks.

The Securities and Exchange Commission, Office of the Comptroller of the Currency, the Federal Reserve and the UK's Financial Conduct Authority are expected to charge the company with poor controls surrounding the giant bet, which ultimately cost the company more than $6 billion.
