I'll be very quick.
I welcome the question. We actually have two separate capital budgets within our capital vote that you see in the estimates. One of those capital budgets lets us reprofile the money that goes unspent into future years, with tremendous flexibility, because the liabilities for those assets are out there, and the Department of Finance accommodates us in moving that money to match the delivery schedules.
For the second part of our capital budget, there is far less flexibility. To the extent that we're acquiring assets out of that part of the capital budget, it presents us with serious problems. One of those problems arose in 2010–11, where we lapsed about $950 million—not the $2.4 billion that's been alluded to. About half of that $950 million was associated with projects that slipped. The liabilities for the assets are still out there when they get delivered, and we will have to find that money elsewhere in the budget in the year those assets are delivered.
The member's question is right on, Mr. Chair. It does present problems, and we do have to manage these very difficult cashflow changes occasioned by the slippage in project deliveries.
I won't go on, but currency exchange is a significant contributor to this issue that we have.
