I can give you a little explanation of that, Mr. Chairman. The exact routing and logistics would not be known to me, but I can tell you a couple of things.
One is that there is trade in coal both ways, and it is a significant flow of different types of coal in both directions. It is duty-free in both directions currently on an MFN basis for both Canada and Ukraine, so there are no tariff concessions that apply. That product will continue to be duty-free.
With respect to the volatility or the significant change in volume, as you know, this being a bulk resource-based commodity, there are different suppliers from around the world, and price sensitivity is another supply and demand factor. These volumes tend to be characterized by a certain amount of fluctuation over time.
