Well, there are certain chemicals that are shared between both what we do and what Dr. Lem does. We have similar base materials of very sophisticated enzymes and other base chemicals that are primarily manufactured in the United States.
With regard to why those have not been manufactured in Canada, I'm not the best person to speak to on that. I suspect it's because the border has been so open and fluid over the years that a domestic supply wasn't really necessary. There's such a large manufacturing...and it's all based in the United States that it was simply easier to get it there.
