I'm not sure there's a simple answer to that, largely because the contract itself is designed in a modular fashion.
As a contract, the first obligation they have.... We, the department—I don't mean Natural Resources for everyone, but the department calling the contract—would carry what I will call a contingency fund, so the ESCO, the energy service contractor, would go in and do the assessment of the building. They would build up a suite of adjustments or major retrofits they would undertake, and each one would be costed. The department then could say it was interested in some—say, three or five—of the adjustments, so the contracts may be very short. Or they may actually go for a number of years.
