 Well, the chemical industry is a sort of bellwether industry. It's a very early indicator of what's happening in the world economy. We produce the basic building blocks from which everything else comes. And I think we've seen a great recovery since the downturn of 2008-9. And we're just seeing that coming off the boil now. We're just seeing things coming, slowing down. General demand is beginning to slow down. And that's really, I think, related to the troubles that are going on through Europe in terms of lack of confidence. So that's the issue that's around at the moment.
