I think it's definitely worth looking at.
As I mentioned, from our perspective we've had the flexibility and the powers that are needed to introduce that. All of our decisions have been unanimous, and I've been involved in all of them over the years. We've based them on the record we've developed and on very detailed discussion in these cases, so I would be cautious in terms of putting anything hard into the legislation that might not fit with the flexibility you might want going forward.
