I don't see what the alternative to risk management is. If it's just getting rid of the models and instead using the smart people who can figure it out? How do you train them? What do you teach them? Do you just put them in a cockpit and let them stumble for 10 years of their life and then after that they're good at it?

That is, many times we're not risking our own money, we're risking somebody else's money, or maybe that someone is going to back stop or downside, but we still get the upside.

You know, some of the portfolios we might consider buying are portfolios which would do especially well if we have an economy-wide, or I mean, a global climate change that impacts us very negatively there are some companies that will do well, and so it might make sense to hold some of those in your portfolio.

The collateralized debt obligation, the CDO, is a structure which allows you to more or less continuously choose how much risk you want to take in a whole batch of securities. And the reason why they got us into so much trouble is that it's hard to figure out how much risk you really are taking.

A lot of ambitious code has been written into the law for those and we will have to see if it actually works, if we have another example of a big financial institution going bankrupt.

I think that's something that investment banks have worried about for a long time and are continuing to worry about, but it's not an easy solution when you have lots of people betting the company's money, how do you really allocate those risks? How do you make sure that the people that take the risks are feeling the risks in an appropriate kind of fashion?

I'd like to see a little more action on the energy side of things. I've been pushing for some kind of a carbon tax for years, and it seems to me we've had lots of opportunities to do it.
