There are net-gain systems in place that typically involve some kind of habitat banking system to make them work. We've looked at those a bit. There is lots of controversy around that habitat-banking approach. Some people are very much in favour of it; some less so.
We're not convinced that these systems aren't a good thing. We think there is possibility there. We don't have a specific program model in place that we believe would work yet, and I don't know of anybody in Canada who has one that everybody else is in agreement with.
