We do extensive due diligence on each of our partners. We make a judgment call on whether there are any black spots on their record, whether they're significant enough that we want to walk away from a deal, or whether we see a change in management and the way they are going forward. So it is a very important part and an extensive part of our analysis of whether we would walk away from a deal or whether we would enter a deal.
The other thing that's of consideration to us is to what extent the indigenous people benefit or are harmed by any public-private partnership. It's incredibly important to us that the indigenous people who live in the area in which this public-private partnership will take place are advantaged by this rather than disadvantaged.
