That's a great question. To give you an idea of the disparity.... In the U.S. on over 30-month animals.... In Canada, we remove over 50 kilograms of this material. In the U.S., they remove one kilogram. That's just how wide a competitive disparity there is there.
We've set up and are working with the agency on an expert working group right now, so we're assembling that group and we're going to really dig into this issue, hopefully over the next four to five months. Hopefully by late summer we'll have some more recommendations ready on it.
