As I indicated, 800 hospitals applied for registration, and 169 were registered. As far as we can tell, some of them are still doing transplants. There is that form of a black market. We didn't include that in our calculations, because it's hard to get hold of.
The reality is that like everywhere else, there is a much bigger demand for transplants, even in China, than there is supply. Even in doing 100,000 transplants a year, they're not exhausting the demand, and they are charging high prices.
In addition to all this official stuff, sure, there is a black market in China. What that would do is produce figures even beyond what we've produced.
