I'll approach this perhaps from a different perspective.
Currently parliamentarians vote on operating expenditures as one number. Going forward, were this to be adopted, you have operating expenditures that would be cash, most of the program expenditures going out would be cash, and then you would have non-cash expenditures, of which amortization would be one. But also if you take the case of provisions for environmental liabilities, those would be non-cash.
Now, you could almost see a world where you might have a mix in how non-cash expenditures were dealt with. Regarding the amortization of fixed assets, you might say yes, that's statutory; we've voted on the acquisition of the assets, and that just follows through. But on an environmental liability, parliamentarians might want to say no, we just don't want to be informed of that; we want to actually vote on it.
So I think the models are not necessarily exclusive, one of the other. Depending on the nature of the expense, you might say that there are some we accept, because we've voted on them previously and the amortization follows as the consequence, whereas others, environmental liabilities, provisions for lawsuits, and so on—
