So people have been talking about trade repositories and swap data—this is the system by which all those derivatives are captured and actually collated so, actually, people can start to understand where the risk lies. You will recall, during the major meltdown in the world financial crisis, a lot of it was driven out of derivative trading and where people didn't actually understand the full amount of derivative risk that they had. So, as a result of the G20 coming together in September 2009, there were rules that were put together to try and make sure that from a worldwide perspective, there was enough understanding of where these liabilities lay and who was holding them, so that if ever there was a situation, it was clear where the liability actually lay.
