Thank you for that question. I'll just ask my colleagues to jump in if I don't have this right.
For big equipment and capital equipment, basically it's the historical cost that has been depreciated. So it's like a net book value. For example, at the Department of National Defence, I think the figure was about $25 billion. The historical costs would have been something different.
For inventories, again it's the actual cost that we paid to buy those things. And unless my colleagues jump in and correct me here, I'm not aware of any situations where for things like equipment or inventory we actually increase those values. It's always the historical cost.
Now for land holdings and buildings, I believe it's the same. We use the historical cost as well.
