Maybe the last question will go to Dr. McCabe, because I'm going to run out of time quickly.
We talk about value-based pricing. Would you try to expand a little bit on that? We have what the listing price is, we have what the sale price is and we have this whole negotiation that goes on in-between. What can patients actually pay, or are we still continuing to be worried about what provinces can pay or what plans can pay? There is a whole bunch of different payers. Who do we actually work with here?
