I'll go back to what Mrs. Russell said, that we removed the speed bumps; we removed the speed bumps in the United States. And the question is—and there has been a lot of discussion on this in the United States, where Mr. Masters and I have been quite involved—how do you put back the speed bumps to make sure that you basically look at these markets and understand what is going on? There is a movement here, and the CFTC has to look a lot more into the data and reclassify them, and I think in September we're going to see a much larger reclassification of the data to better understand the dynamic of these markets. They're complicated. But at the same time, I think it's also a political battle, as you have certain lobbies; and the financial industry, which has not been doing particularly well, doesn't want to see that loophole closed, because it's the only place where they're making money right now.
So you have different interests at play in the United States, and at the end of the day, it's a U.S. issue of how you put back the speed bumps and make sure you regulate your markets.
