Let me just very briefly respond.
I guess the issue is whether Parliament would like to have the ability to decide that the bus should be sold--not whether a coat of paint has extended the life but whether the government shouldn't have that bus, should sell it, or we should not be changing them. So the balance sheet of the country should change.
If you vote the cash, you are voting for the amount that affects the government's balance sheet. If you don't vote the amortization, Parliament is not ever voting for the amounts that eventually affect the bottom line, in that sense. You're only voting the cash, not the actual fiscal consequence.
If we're clear enough about it, it's not...and that's the issue of the transparency. I'm not saying it's not doable, but you don't have that further level of control on an ongoing basis.
