I don't have those figures with me. I believe we could obtain them.
I could tell you in very rough terms that the withholding tax in respect of Canada-U.S. interest payments is approximately half of the world total, so very generally you'd take these numbers and double them and you would end up with the withholding tax associated with interest generally worldwide--or were you asking specifically about the figures for the U.S. in the last couple of years?
