Yes. The differences really had to do with the performance reporting of the railways in the U.S. system, and that includes CN and CP in respect of their U.S. operations. It is the data they report on a weekly basis and on a monthly basis. Within the space of a week, that information is on the website of the Surface Transportation Board and is visible on a railway-by-railway basis, and it shows a breakdown of 23 different commodities. It has a different car count for pulp and paper, for forest products, for coal, for potash, for you name it. There are 23 different categories.
To us, that is really the minimum level of detail we need to see, and because of how large the country is and the fact that CN and CP operate pretty much across it, we would like to see that on a railway-specific basis as well as on some kind of geographic granular level. Otherwise, it's not useful.
