There are basic financial indicators, financial statements and others, but the underlying assumptions and the underlying data—passenger movements, cargo movements, assumptions around required capital spending, debt load—all help us to not only properly value that asset but also integrate that into our planning.
It's interesting that you mention UP Express. Highways will always play a role in the Canadian transportation system, but for those who live in dense urban areas, I think the goal should always be to leave your home, start with public transit and end with public transit. It's taking that very important airport link or public transit to that airport link, getting on a plane, getting on a train and going where you want to go. Then hopefully at the other end, it's unfolding that in the same way and getting back home with your suitcase. Only having taken public transit should be our objective. I think it's something that can be realized in the GTA and all over the country in dense urban areas.
