I think you have to step back a bit, because you have to look at the existing NAFTA, in which there is absolutely no protection on aluminum, no kind of provision on aluminum, that requires a certain amount of aluminum to be used in the production of cars. Under the new rules, manufacturers will have to have at least 70% of their purchases of aluminum come from North American sources, which means largely Canada, and more specifically largely Quebec. That's a significant improvement.
There is a difference between the steel and aluminum approaches, given that in this most recent amendment to the protocol that we negotiated and agreed to on December 10 there will be a requirement for steel to be melted and poured in order to qualify as originating in those purchases by manufacturers. However, we also have already established a process whereby we're monitoring imports of aluminum into the North American market. If we start to see a significant proportion of aluminum coming in from other countries, we will address that issue by raising it with the U.S. and Mexico and making the argument that aluminum, for that reason, should be treated the same way as steel with respect to that provision.
