In my view, our primary interest is to just make sure there's a thoughtful process, whether it's a royal commission....
A number of years ago, there was an international tax panel that reviewed the international rules. I don't think we're as fussed about how it's done, as long as it's a thoughtful and comprehensive review. Going in, you can't say if it's going to be a tweak or a major overhaul because I think part of the exercise is to see what's working and what isn't and to determine how much work there is to do. That's the first step of a review. I think we need to go into it with an open mind and see what we need to do.
