In terms of the $2 per tonne estimate in savings for the revenue cap, that is just an order-of-magnitude estimate that was developed in conjunction with the Canadian Transportation Agency. As you're probably aware, in Bill C-11 there's a provision that allows the government to ask the agency to have a look at the actual maintenance costs and adjust the revenue caps to bring them in line with the actual maintenance expenditures that the railways are incurring. That will be done, and I wouldn't want to prejudge the results of that.
But we're comfortable that the $2 is a good order-of-magnitude estimate.
