This information that we would have provided to the OAG again reflects again our planning. We would have looked at the historic behaviour of people at these income ratios in terms of their ability or propensity to pay, and run it through analysis.
In other words, as we gained experience with who was claiming these benefits and what the amounts were, we back-tested that against historical data to see what the profiles of those kinds of taxpayers were. That led us to a $1-billion number. Again, this led us to consider whether we would need 50 people on this, or 5,000 people. That was the purpose of that kind of analysis.
