Well, I have some knowledge of this infrastructure question, and I can assure you, there are different ways of going at it.
What I'd like to do is go over to Mr. Benevides, who suggested he had some comments on this and would like the opportunity to deliver them.
I'm wondering, sir, if you wouldn't mind perhaps using, as a worked example, the case of potash and ammonia as you go through your refutation or comments.
