In contrast to some of the past discussions we've had with the U.S. on these issues, they have acknowledged that what they are trying to do could cause disruptions in supply chains, and they've indicated that they want to avoid these kinds of outcomes. We've had direct conversations with them at virtually all levels, and they've indicated an openness to talking to us about coming up with results that would not cause disruptions in that integrated market, those integrated supply chains.
At the end of the day, I think it's recognized that it would not only serve us better but also serve the U.S. better if they don't impose artificial barriers. If they don't, it would lead to a better result economically and environmentally for them. I think it would serve both of us very well if we continued with the kind of integrated market that we have established over a long period of time.
