Again, I think you can start by coming at the problem from the two extremes. Are there too many assets? If there can't be any more funding, then does that mean there are too many assets?
If there are not too many assets, and that's the stock of assets you want to have in the National Capital Commission, and they need to be properly maintained, then you have to make sure there's a proper funding. There can be anything in the middle, trying to balance those two things off.
Certainly, just going to what the assets are and what it's going to cost to maintain them, and saying, “Here's the amount of money that's needed” is the very simple calculation in the first instance.
I think, though, there also needs to be that very deep consideration of what it is we want the commission to do and what assets we want them to maintain. Once that is done, then really, the maintenance number needs to be a long-term plan of what's needed to manage the life cycle of all of those assets.
Once the assets that need to be maintained are decided upon and there's a plan for life-cycle management, it's becomes a fairly simple exercise, and the cost number really just falls out of that.
