Well, as I said, typically we don't do that because it's extremely difficult and you're getting into the area of cost-benefit analysis of a policy. We don't really do that. We only look at the direct financial cost or benefits of any program in that form.
We're trying to be more objective in this, simply because once you get into those areas you're going to have to make huge assumptions, and it becomes somewhat subjective as to what the benefits are of something like that, for example.
