I'll try to give a quick answer.
If I were to talk to the retail companies that imported product and supplied those farmers in eastern Canada, whether it's in P.E.I. or in Quebec, what they would say is, in order to secure supplies for their farmers last year--in July, August, and September--they bought fertilizer from around the world at globally high prices compared to where they are today. That has caused the market dislocation that you're seeing.
In terms of profitability, publicly traded companies like Viterra and Agrium have announced that they have made writedowns in the value of their fertilizer inventories. Yesterday, Agrium came out with a $60 million first quarter loss as a company. So the upheavals in the marketplace are definitely affecting fertilizer companies.
Bill Doyle made a statement to stock analysts last week on the demand for potash and cutbacks in production to meet the demand that was in the marketplace today. He also talked about the need to make something like $10 billion to $12 billion of investment in new mines. He said they needed those prices in order to sustain that investment.
