I would like to come back to this question of sole source, because there has been a lot of debate about that. I think HealthPRO has said that they are now looking at other backups, and I think that's very important.
I just wanted to focus on the patented drugs. We focus a lot on the generics, but in actual fact, each patented drug is a sole source. I'm not clear about how one would deal with that, because you're dealing with an individual product.
I don't know if the HealthPRO representative would like to answer. I don't know whether you deal exclusively with generics or whether you're dealing with patented drugs as well. How would you deal with the sole source?
