While The Bank of New York Mellon's (NYSE: BK) earnings report wasn't particularly exciting one way or another as it pretty well fell in line with expectations, Motley Fool financial analyst Matt Koppenheffer feels that can be a good thing. While the market sold off on the stock a bit today -- partly due to concerns about the shrinking net interest margin, which has been a pervasive concern across the board among banks this earnings season -- as a bank with 78% of its revenue coming from fees, net interest margin isn't nearly as much of a concern here. In this video, Matt gives us a few other reasons to be positive on the bank.
