Yes, sir. We would always look at the long-term costs, whether for leasing over a long period of time or for acquisition and maintenance, and we would compare the proposal that the minister brings forward against a range of alternatives.
The objective is always best value for money. Features come into play, though, that might determine an outcome that was not necessarily the most inexpensive; the value could be the size of the property that's required or the timing in terms of the availability of the property. So there may be a case in which it would be cheaper to lease on one side of the river or the other, but there isn't a building of the right size available at the right time.
