I have just a very brief question. I'll stay with where we were with our friend from ARC.
Have you or any of your colleagues done any research as to how much of the current valuation of the Canadian dollar is in part due to our export and sale of petrochemicals? I was just looking over the amount of transport that's made up of our foreign investment, as well as how much we're exporting in valuation dollars.
I was just reading an article in The Economist that was talking about the Canadian dollar increasingly becoming a petro dollar. Have you done any research into this? Has anyone attempted to assign a value of so many cents on the dollar currently at our trading rates?
