If I may, I'll make a comment on that. I think our experience is that the value of accruals and accrual concepts is in the depth it gives to financial statements and the possibilities it opens up for financial analysis.
If I can take one very stark example, prior to going to an accrual basis, we would not have had a clear understanding of the liability attached to our public sector superannuation arrangements, which back in those days were in a fully defined benefit scheme. We now measure and value those things. Two things have happened on the back of that information, which could not have happened, I think, without that information.
The first is that we've moved systematically to close our defined benefit scheme, to manage the liability by effectively putting a lid on it. The second is that, back in the middle of the last decade, the government of the day put in place a future fund, which is effectively an accumulation of surpluses put into a special fund in order to fund the liability. It's sometimes characterized as a sovereign wealth fund, but it's actually more limited than that. Now, would government have taken such big steps on such big issues if they hadn't had some confidence that they understood what the numbers were, and if they hadn't had confidence that they were really tackling the right issue in the right way? My suspicion is no.
I think the value is in that: what it adds to analysis. Pragmatically, I think, appropriations for departments are simply about what is the most sensible way by which you get resources to the right place so that people can deliver programs, in such a way that Parliament is happy that it has discharged its responsibilities of ensuring that monies are only taken from consolidated revenue against a proper appropriation.
