We have a methodology, which is published on our website, about the process we go through. We will go through all the risks of a project—which are appropriately transferred to the private sector, what we evaluate them to be worth—and on the other side of the equation we will take a look at transaction costs and financing costs and then we'll conclude.
We'll also conclude at a screening level, even at a high level, whether or not something is even worth doing a deep dive on. If we think that yes, it has a chance, we will do a very granular, quantitative, analytical process to determine whether we think it's the right approach.
