Sir, again, I think it highlights why it's important for you to see not only our assumptions in terms of income shares going forward over the projection period but the Department of Finance's as well. It is so that you can understand what's happened to those underlying tax bases.
Just to underscore your point, sir, which is well made, what's happening, basically, over the short and medium term is that as the output gap closes in our economies, we get back the potential in the medium term. The IMF says 2014. The PBO says 2015. Those tax bases, as a percentage of the economy, will go back to their trend, and I think that's what we're seeing. We're seeing the output gap close now.
