There is a role for the private sector. I wouldn't put a percentage on it because it would depend on specific situations. The tradition has been a third, a third, and a third. I would say that when it's a third, a third, a third, the municipalities end up paying more than a third, just because there are all kinds of costs that are implied in the exercise. And there are limits to the capacity of municipalities to finance one-third, one-third, one-third.
