I'll answer your other question first. Again, on corn used, I forgot to answer your second question, which was about whether our plants contract directly with farmers. Yes, they do. There's a variety of contractual arrangements they can make to supply their grains directly to the ethanol plants.
We're talking about two different biofuels. When you talk about corn, that's used in the production of ethanol. When you talk about canola or oil-based oilseeds, you're talking about the production of biodiesel. It's simply a different fuel.
Tim, you might want to comment.
