Maybe I'll start and then Stephen can talk a little bit more about the overall environment.
I think the reality is it's a shifting environment. Regulations change all the time, and countries change their regulatory regimes all the time. The technology has made things quite different, whether it's compliance kinds of technologies, regulatory technology.... It's not a static environment, and I would say that each of the initiatives that has been undertaken has gone some way to address the issues, and then the environment keeps shifting. I think it goes back to the point about agility that the economic strategy tables made. It's really important that we have an agile system that is able to keep up. I think it is a shifting environment and that agility is the only thing that's going to keep us ahead.
