I'll make a couple of comments. I'll answer that last question first.
The interesting scenario that happened is that we had negotiated commercial rates. I'm going to use the Burlington Northern into Lethbridge as an example. There were products moving in and out of Lethbridge under the bilateral agreements on creating through rates that Janet referred to. What happened is that when extended interswitching came in at a prescribed rate, the shipper paid essentially the same amount, we got paid less, and the revenue for the U.S. portion of the haul went up as a result of the application for interswitching.
