I mentioned the key one I think has been with regard to the rail sector. We're a key leverage for farmers in terms of ensuring access to the rail system and also in terms of determining the rates.
We also play a major part in affecting the competitive balance in the grain industry because we're the first point of entry for the carriers. Independent producer terminals exist in western Canada where they don't exist in the United States. The reason for this is that we negotiate a framework on the rail side and then, in turn, deal with farmers on how they want to deal with the system.
So there are a number of key commercial pieces that we provide on that front. I would say that as the sector becomes more concentrated--the marketplace that Larry spoke of--in order for it to give you a price discovery that's reasonably balanced, it has to have a reasonable access to both providers and demanders of any service or good. As we look at the concentration that's happening on our side, we've seen their costs go down on the fertilizer side, and because prices have escalated, fertilizer prices will be almost double springtime values versus what some of the other players have seen.
So there's a very significant market power imbalance on the farm input side that we at this point are less directly involved in.
