I've asked our people, "Why don't we just put a revolver on top of our basic loan?" Make it easier for the client.

Look, every institution will make mistakes. I acknowledge we make mistakes, and they can hurt my reputation and our company's. But you also must be willing to let go a little bit, trust others, and not always be so stringent, provided you have robust controls.

Economies of scale are a good thing. If we didn't have them, we'd still be living in tents and eating buffalo.

Japan, Europe, [and] America probably [are] better than last year [2015], not China.

Over the longer term, China will grow by about 6% or 7% per year. The Chinese authorities usually react pretty quickly to unfolding economic events, and you've seen them recently change a whole bunch of policies to be more conducive to growth. They have the power and capability to macromanage the economy - to accomplish their growth objectives - which means they're pretty much going to come close to what they say is going to happen.

I do think there will be more Japanese companies expanding out of Japan, and there will be more cross-border flow from Japan.

The toughest are people mistakes, when you put the wrong person in a job. Sometimes you're too slow to move them out. Or not getting the right people involved to solve a problem, or doing something out of anger; you learn, just don't do that. But I'd have to say the Whale was one of them, and I would also have to put Bear Stearns and Washington Mutual on the list at this point.
