The banking giant is negotiating with federal prosecutors to iron out a $13 billion deal that would resolve a range of probes stemming from JPMorgan's mortgage bond sales before the housing market went bust.

This includes the question of whether JPMorgan can count $5.1 billion in recent settlements with mortgage finance companies Fannie Mae and Freddie Mac toward the eventual $13 billion tally.
