Thank you very much for the question.
Now, we're the only class 1 railway in North America that operates across not just two countries, but three. We spend a lot of time thinking about this sort of thing and the need for regulatory harmonization essentially across North America, about minimizing any kind of trade barrier or regulatory barrier that causes delays at the border or somehow interrupts the efficient movement of freight. I'd want to take that back and think about the specific kind of structure that you have in mind there, but in general we are certainly supportive of efforts that look at regulatory harmonization.
