Thank you.
I'm going to turn back to Mr. Harvey again, because he has this background in the mining sector.
You mentioned some disputes involving investments. When I hear of international disputes with Canadian mining companies abroad, they often seem to centre around taxes, local taxation and countries trying to get some benefit from those mines in their own country. I don't know the details of most of those, obviously, but I have heard of situations of Canadian mining companies abroad opening a post office box in Luxembourg, for instance, and then work it so that their tax is in Luxembourg, not in Canada or in Mongolia or wherever they are actually working. The people in Mongolia don't get any money and the people in Canada don't get any tax benefits.
I wonder if you would consider those to be non-tariff barriers. How do Canadian companies working abroad decide where they're going to pay their taxes and whether they pay taxes in a fair way or not?
