Yes. I do recall that evidence at the Senate inquiry, Minister, but I also recall that those witnesses said during the inquiry that they hadn't undertaken specific modelling to bear out that assessment and that that was a general assumption that they were making without being able to put numbers behind it.

Can we go back to the Treasury modelling, though, and the productivity impacts of these changes so I'm very clear that I've understood what you've said. Treasury haven't undertaken specific analysis on how these tax changes impact productivity. They come up with some aggregate number based on all of the provisions that are within the budget and say, 'This will be the overall impact.' Are you saying that you don't have to hand an itemised list of the productivity impacts of every budget measure? Obviously, every budget measure aside, specifically what I'm interested in hearing about today are the CGT changes and the negative gearing changes.
