Mr. Perez, I have a quick point on one of the comments that you made before.
This is interesting. Every time you try to develop a policy, you always want to create a policy that is comprehensive enough, yet not so comprehensive that it restricts your flexibility down the road, because as you pointed out, who knows what fuel prices will be. In the world we live in right now, we can speculate that the prices won't go down in the future.
So what is that right level of detail, from your perspective? You said don't rush to get to a comprehensive strategy. At the same time, we've got to get somewhere, sooner rather than later, so how do we create something that is flexible enough for us?
