The only experience we've had is on 3P projects. There, it's an owner system. There's a 30-year lease. The energy is guaranteed over 30 years. At the end of that time, the building is turned back over to probably a public sector entity. I haven't had the same lease experience that these gentlemen have had and are talking about.
But that's one thing: if you're going to own the building, that's certainly one approach you could take, a 3P approach, to achieving this objective. On the lease side, it's certainly going to be more complex.
