Sure. Yes, sure. Sure, William, there's kind of 3 variables there. Number one, ideally, we'll run 100% production capacity, 24/7, so every day of the week. We don't have unlimited storage at our sites. And so I think that we generally have to sell forward so that we -- the goal of the operation is to run maximum production. That makes you the lowest quality -- it lowers your cost as low as they can be for production, and we don't have unlimited storage. So you always have to sell some portion of production forward so that you can maintain full production and you don't get caught where you run out of storage capacity for product. So in those situations, you might have to dial back your production level. So that's one issue. The other issue is that the buying patterns of our customers. We have people that buy -- they buy both forward tonnage and spot tonnage. And we have to be in the market selling when there's liquidity. And when I define liquidity, I mean, when a customer -- big customers are buying product. So every year, we have the UAN fill season in the summer, where customers buy somewhere between the third quarter product and the fourth quarter product. And if you don't participate in that, then they could satisfy their needs with other -- from other producers. So you have to participate. They have similar dynamics in the ammonia season for the fall and the spring. And so you have to participate when the customers are buying. And so that -- we meet the liquidity when it's there. We can't sell all our product at spot prices. I think that's a common fallacy that a lot of people, when they look at this business, why can't you sell all your production spot market? Because if the liquidity dries up, then we don't have an outlet for our product, and we might fill up all our tanks and not have a storage for the product. So we have to balance that. And sometimes, we look really smart and sometimes, we look really stupid because we're either in front of the curve or behind the curve. And in a rising pricing environment like 2021, we always look behind the curve, but because we were selling forward, as we came into this year, the market was very strong in the fourth quarter, and so we were able to sell first half '22 product at much higher prices than we experienced during the rise in 2021. And so we've got a good book on we can run comfortably full out production 24/7, and we have a good book of business so we can satisfy the customers. We still have some more to sell in the second quarter, but we're in great shape and the market pricing is much higher than it was in the second half of '21.
