I can speak with regard to the C.D. Howe and the USITC reports if time allows.
In the USITC reports, if you look carefully, there are probably three numbers, so three different scenarios. If there is no policy uncertainty reduction in the model, they have a negative for the U.S. economy of $22 billion. If there there is some reduction in policy uncertainty done in a certain way—and we can discuss that for a long time—then there would be a benefit for the U.S. economy of $68 billion. If there is a lot of reduction in policy uncertainty, you get $235 billion—I think that's the number.
C.D. Howe did not do any policy uncertainty, and we did not either. We know that it is good for business if we reduce uncertainty, but it's very hard to model.
