All right. Well, what I'd say is you didn't have much nitrogen imported into the U.S. over the winter months, and people waited, I think, too long on nitrogen. And so that's why it moves very quickly. As you know, nitrogen's the most volatile of all the nutrients, and so the movements are -- can be exaggerated both ways, both up and down. And we think overall that you might see a little bit of a correction in nitrogen. In terms of the urea pricing, you've got just very high levels, and we don't think that, that is sustainable over the medium to long term. We think ammonia is going to tighten up here. As you start looking at competitive producers of ammonia around the world, the Russian situation, Ukrainian gas, the impact of Russian gas in Europe, you've got very high costs, nitrogen comparing to what's going on in North America because we're blessed with shale. And so I don't think you're going to see a lot of imported nitrogen coming into the U.S., much like you saw during these last few months. So the nitrogen market is, we think, over the short term, going to be pretty good, but not as ecstatic as it was here during the 1-month or 6-week period that urea went through the roof. In the phosphate business, maybe a little bit better than what people think. Ma'aden, probably will be half of its productive capability in 2012. They've had some ramp-up problems. These, too, are typical of what we've seen, what we see in all these big projects whether it's potash or phosphate, even delays in nitrogen plants. These things always take longer than people think they're going to take. And so, we see some pretty good demand coming. Phosphate, of course, is more dependent on India. So if India reengages in phosphate, which we think they will, we think that phosphate business will be pretty good. And a big pressure you got in phosphate is rock, the raw material. And you've seen some of these permitting problems in Central Florida, which we're blessed not to have at Potash Corporation because we have a life-of-mine permit in Florida, and we've got a 30-year permit in North Carolina. So we don't have these issues. But I guarantee you these new mines, that are going to come out, are going to have big permitting issues. And so you're going to have higher-priced raw material and for people, who are not vertically integrated into their own rock, I just, boy, they've had a tough row to hoe, they're going to have a tougher row to hoe and that represents a significant part of phosphate production. And I think you're going to see some people fall by the wayside there. So phosphate, I think, is going to be a little bit better in the medium term.
