JPMorgan Chase & Co chief executive Jamie Dimon was meeting Thursday morning with US Attorney General Eric Holder as the nation's biggest bank attempts to end federal and state investigations into its liability for selling shoddy mortgage securities, according to two people familiar with the matter.

The settlement talks in Washington come after the US Department of Justice threatened to file a lawsuit on Tuesday over one of its cases.

Dimon's meeting with the highest-ranking law enforcement official in the United States was scheduled for 10 a.m. (16:00 SA time), one of the sources said.

The meeting follows negotiations between JPMorgan and federal and state authorities over the bank paying as much as $7 billion in cash and $4 billion in consumer relief to settle several investigations.

The talks have been described as “fluid” and filled with uncertainties over exactly which claims against the bank would be resolved. - Reuters
