In terms of consumption, I don't know exact numbers. We know most rare earth products are produced in Asia—China and Japan. Canada is buying finished products. There is a need to study and understand how much rare earths is included in some of the products we consume.
I think in cars it's been quite understood and then I guess it's a question of understanding how much we consume in cars and then other things, wind turbines and so forth. That is a way of understanding how much the Canadian economy is exposed to rare earths in tonnes.
I'm fairly sure we purchase rare earth compounds. I know of one company that produces fluorescent lights, which use rare earth compounds, europium and so forth, but I'm not sure there is a comprehensive study around that.
What was your other question?
