Okay, absolutely.
The easiest way to explain this is to say that in the case of a growing economy, in a country with a growing population, it's not possible to go in a straight line from our current level down to our target. We have to take measures that take effect over time, and this approach will bend the line down to our target.
We look at the 2020 number without government action, and then we take actions that over time will start to bend the line down. We believe we're about a quarter of the way there, but there are still many more actions that need to be taken to get us to the 607 target.
