Well, we've been asked to provide financial analysis around the F-35. We're undertaking that analysis. We hope to have a report to parliamentarians before Christmas. In response, I would say that I still think there are a number of questions about the costs, and there is some uncertainty with respect to the F-35.
On the other issues mentioned, such as the report on the G-8 and G-20, we did some work for parliamentarians in advance.
It's true that we have not seen even in the 2010 budget or in the fiscal update what adjustments were actually made in the fiscal framework for those expenditures. I think there's uncertainty. But I think at this point the work is now really over to the Auditor General to kind of look at the receipts. I'm not sure how much more value-added we could provide on that.
On corporate tax rates, we could do some work to look at what the rough costs were. We don't have a great corporate tax model. We could work with Statistics Canada. We've done these sorts of estimates before. We could do crude estimates. I think Finance already put out roughly what those estimates would be, I think in the 2000 statement, when they made the reductions in corporate income tax. So there's some information out there.
What was the fourth one?
