Thank you.
There are very simple measures of efficiency in terms of the number of our staff and the amount of funds we expend on a particular operation. They are simple measures of our efficiency, and those we can provide in detail to the committee, if you prefer. Those are measures of efficiencies and very simple measures of efficiency.
In essence, the denominator hasn't really changed. The types of services we provide have not changed. The infrastructure, in terms of towers and radar installations, has not changed. The denominator hasn't changed, but the personnel and the centres that provide those services have. It's a very simple measure of efficiency.
