Absolutely. I think there are a lot of examples in the States of how these banks get established and who invests in them originally to get them going, but productivity does change over time.
In the case of OPG's Big Island wetland, I believe there was a hypothesis or a projected productivity credit. What would the credits look like in year two, year three, year four and year five? As wetlands age, they actually become more efficient and more productive in their capacity. There is that level of technical expertise that comes to the table and starts talking about those things.
Specific to someone going out and doing that work, often organizations like OPG don't necessarily have the in-house technical expertise to do that type of work. There are speciality organizations that do, so in allowing that partnership to happen, again, you can almost guarantee better outcomes when you have an established bank, established credits and established productivity. If I have to come and buy 10 credits from you, the regulator can insist on my buying 12 and ensuring there's a better outcome for any uncertainty associated with the project.
