That is quite a slow process, which brings me to the member's next point, which is that revenue and profit are not the same thing. The reason I was using revenue is because I can see revenue. But the nature of profit is not always so easy to discern, particularly when it comes to international companies where, due to the nature of tax arrangements and so on, it is possible for firms to have quite high revenues, but quite low profits in one territory if they think that that forms an advantage. So we've been using revenue, recognising that it's not a perfect measure, but because, you know, we can't look through firms into all of the finer details of their accounts, it's not really possible for us to use profit as a basis of comparison. The other thing, of course, is that you can compare revenue between different companies, but you can't easily compare profits between different companies for the same reason. So revenue is not a perfect measure, I acknowledge that, but it's a more functional measure than using profit in this regard.
