I think there's a really easy answer, and that would be we have agreed under the terms of the gross lease to accept all the energy cost risk. The government would get the benefit of energy costs, should they ever fall. It doesn't happen that often, but it does from time to time. Another way of approaching it would be to say the energy costs are this much going into the deal, they'll be indexed on the way through, and if they happen to be any less than that the landlord is free to use that as a means of recovering investments in equipment that would reduce energy, and they would have to prove it. And they can only get it.
So the landlord then has an incentive to pursue the savings because they're now available to the landlord. Believe me, lots of landlords would be all over it. PWGSC occupies millions of square feet across the country.
