Before I go to Mr. Rayes, yes, that's going to be part of the discussion we can have regarding the whole schedule in the broader context as to what we do first. We have to line that up.
In the meantime I will do some consulting about this, Ms. McPherson. I think you raise a very good point as to the scope of the study. I'll leave it at that for now. We can probably discuss this again a little later. Thank you for bringing that up.
Mr. Rayes.
