This is an easy answer. In 1993 we borrowed $130 million on a triple-B rating. In 2003 we refinanced with an A and saved $20 million. That difference was all in the rating and in what we paid the bondholders. It is significant. Just the movement between an A and an A minus or to a B is dramatic.
As I said earlier, there's only one place we can go to recoup our costs if they escalate significantly, and that is to our toll payers—that is to Canadians, Americans, and visitors to the two countries.
Again, I need to emphasize that this is discussed further in some of the materials I made available to the clerk.
