I already spoke about the cases that end up getting approved on humanitarian and compassionate grounds. Ninety-one per cent of folks who have asked for that after a finding of excessive demand have been successful in being granted visas. On the side of the mitigation plan, you'll see in the answer to the undertakings that over the period of 2013 to 2016 just over 700 mitigation plans were successful. Again, those are two different ways in which some of this is mitigated. The actual excessive demand finding is not the end of the story all the time.
I would also say in terms of the costing using branded drugs as opposed to generics that we actually look at the advice from the treating physician and what that treating physician has prescribed for the individual. If it's a branded drug that's more expensive, such as in the context of HIV, that's what we cost against. We don't want to make a supposition that the person should be on a different drug treatment plan that's a generic and that may not work as well for them. If the specialist says the generic is fine, then we recost.
