NEW YORK, March 7 (Reuters) - JPMorgan Chase & Co (JPM.N) has settled a lawsuit accusing it of defrauding bond investors out of at least $1.2 billion through bad record keeping, court records show.
The settlement of the five-year-old case comes as banks' ability to handle paperwork faces intense scrutiny, especially over their mortgage operations.
Investors had accused JPMorgan of deleting records on $46.8 billion of bonds from roughly 6,500 bond issues that had not been cashed in, and then covering up its mistakes.
