We do get that evidence, and if it turns out that they're not complying with their price ceiling, then we'll take appropriate action. An investigation will be commenced, and enforcement action will be taken; it could go to a hearing.
The reality is, as I mentioned, ceiling prices based on list prices bear less and less resemblance to the outcomes of those negotiations between the pCPA and the companies. The rebates are quite significant, but they're unknown to us.
List prices are a bit more relevant to private payers or out-of-pocket payers, because that's typically the starting point to negotiation. They have a lot less group buying power. They can't come together as a collective and negotiate, and avail themselves of that countervailing power.
However, I don't think there's a need to do that. I think we exist as a mechanism to ensure that takes place.
