I think the concern, chiefly, is more to the point that certainty for business prospects is always the best route to take. I think that being able to count on a reasonable progression towards review and consultation is always preferred for business so that we can make appropriate arrangements to cover any changes that might be moved. That's what our chief concern is. I don't think proliferation, necessarily, of those costs is the chief concern, but it's about the certainty of us being able to move to having competitive choices.
