Of course, the other really important point there is the designation of financial infrastructure entities. Not every financial infrastructure entity is kind of essential to the integrity of the system of the whole, there are some smaller operators who have less widespread systems; smaller stock exchanges would be a really good example, where, whilst there might be benefits for them to be subject to this Act for various reasons—they get various protections and indemnities for example—it's not essential to Government, to the integrity of our overall system, that they be included in this piece of legislation. So we looked at the opt-in, opt-out provisions there, so where an entity is absolutely essential to the integrity of the system, they will be compelled to be part of this regulatory framework, but when they're not, they may opt in to the framework so that they get the benefits of it—but they needn't if they don't want to.
