Again, from the Federal Reserve's perspective, our principal concern is the safety and soundness of the banking system. What we have done recently is worked with other regulators, such as the SEC and the OCC, and in some cases, also with foreign regulators -- the FSA in the U.K., for example, and German and Swiss regulators -- to do what we call horizontal reviews, which is that, collectively, we look at the practices of a large set of institutions -- both commercial banks and investment banks -- to see how they're managing certain types of activities, for example, the financing of leverage buyouts, equity -- bridge equity -- and the like, and trying to make an evaluation of what are best practices, trying to give back information back to the companies and trying to use that -- those reviews to inform our own supervision.
And so we are very aware of these issues from the perspective of the risk-taking by large financial institutions, and we are studying them, trying to provide information to the institutions themselves, and using them in our own supervisory guidance.
