JPMorgan Chase said on Tuesday that fourth-quarter profit fell 7.3 percent, hurt by weaker investment banking revenue and higher legal expenses.

The results cap off a difficult year for Chief Executive Officer Jamie Dimon. The bank agreed to some $20 billion of legal settlements in 2013, with $850 million in the fourth quarter stemming from its deals over its failure to report suspicions of fraud by Ponzi-schemer client Bernard Madoff.
