I'll take a run at the question.
I think the debate over mark-to-market is one dealing with the pro-cyclicality of mark-to-market, which is the point you made. In up markets, you're marking up the assets, so you're encouraging a lot more activity in the financial sector and there's the potential of bubbles. The counterpart to that is the transparency argument, which is the argument that accountants use, which is that whatever a value is, it should be disclosed.
I think the issue gets much more complex than that, and I think that's the reason--you cited the C.D. Howe Institute--to provide recommendations that give a little more flexibility in terms of some discretion in marking to market. One of the reasons for this is that it's very difficult to in fact mark to market securities that are not actively traded in the marketplace.
Part of the problem we've encountered in our markets is it's these more esoteric securities that we've had trouble valuing. The risk in a mark-to-market scenario, without some kind of discretion involved, is mismarking the assets.
I would agree with the recommendation of the C.D. Howe Institute that says we have to look at this more carefully, and we probably have to treat the accounting of financial institutions a little bit differently than maybe we have in the past because it has exacerbated some of the problems we're facing.
