I have a question for you, Mr. West, about the notion of domestic supply.
In the conversations--and Mr. Tracey raised this, as well--it seemed that where these isotopes are produced is actually of significance to Canadians. How important is that? Is it not simply like any other type of market commodity that you can go out and buy, and Canada simply buys them just as other countries have been buying them from you and from us for many years? Why is Canada's presence in the market so critical in Canadian patients getting the types of tests they need?
