So my first comment is, that's an excellent question and very well phrased. And it goes to the heart of the discussions that we have here all the time. We are looking at capital allocation as one of, if not the single most important thing that we do. And there's no question that from a market value's point of view, the landscape is tilted towards buy versus build. Having said that, and we have teams that do a lot of work on this, we've reviewed all sorts of opportunities, including ones I'm sure you're watching that are getting cheaper, and they may well get cheaper from here, by the way. And the issue that you have to remember is that the assets themselves haven't changed. They may be valued in the market more cheaply but they're still the same assets. In many cases, those assets have something associated with them that make them not very interesting to us. It could be that they are short life, it could be that they have significant environmental and sustainability issues. It could be that their geopolitical risk is bad and getting worse from a resource nationalism point of view, or from a health and safety and violence point of view. So and those who are trading in the market don't have to deal with those issues, they can buy and sell and get out if things go seriously wrong, but we have to live them for a long, long time. And so as we go to build the company, we are very, very conscious of all these other, more qualitative factors in trying to build a good strong company. We always start with the resource base and are there any significant risks to it? Is it long life? Is it going to catch several cycles during which we can get our capital back and earn a decent return? We look at labor laws. You know what? I could go on and on, on list of questions. And then finally, even though the market price, the current bid, might be quite cheap in quite a number of these companies, they're really controlled, in terms of trying to buy them out, by 5 or 6 shareholders who own perhaps 30%, and they won't sell for the normal takeover premium of 30%, they all want 60%, 70%, 80%. So that in fact, the valuation that you can take it out for hasn't really in particular for hasn't really dropped quite as much as it might appear. So I can assure you that I personally and our Chairman and others on the team here, are looking at that issue all the time. It is intriguing as this market unfolds but, at the moment, we haven't changed our plans.
