The difference refers not to the cost of the space itself, but to the cost of utilities, so that would include water, sewage, electrical and heat, and that varies. It would include the cost of other aspects of maintaining a large piece of inventory. For example, when we have to move tenants out of one location to another, we conduct a competitive process. When another landlord is successful and we move the people, there are costs in those moves. That's what's built into this total amount.
