That would be a good summary perspective of the 23% difference for the rail cars themselves. They are only a small part of the whole, of course, but they are a very significant part, and the investment in rail cars is a significant item on the railways' balance sheets and is a significant income to our members and a significant portion of the employment of our members in Canada. So we lose something on that.
The problem is more complex than that, of course, because some rail cars only operate in Canada. Some operate internationally and some operate only in the United States. There are little differences in the investment criteria for those, and of course in the tax rates applicable to those. If they stay in the United States, obviously the Canadian railways will lease from our U.S. leasing company. If they're used in international service, they could be either one or the other, whichever is cheaper for the railway, and we generally lose out on that because the U.S. ones will be cheaper, as you've described it.
