Sure. It's a great question, and maybe we'll tag-team on this one.
From look at the transcripts from your previous discussions, I understand that some of the concerns from the Australian experience have been on how funding or appropriations that were intended for amortization purposes were used.
From the perspective of our financial management framework, we have strict policy and legislative controls on how appropriations can be used. There is a statutory constraint around certain kinds of appropriations, such as amortization, and there are also policy constraints in our financial management directives that ensure that appropriations intended to be used for amortization purposes are indeed used for amortization purposes. We haven't had the experience of our Australian colleagues in this regard.
I will ask Chris to briefly mention how we budget for capital, and what that looks like in the estimates in terms of the capital asset and amortization experience.
