That's true. It's not just increased rental rates. It's talking about the increased volume of maintenance costs, the increased volume of hydro being used, the increased volume of the different utilities as a result of perhaps the change in use of the space by the tenants. It's the volume of the operation and maintenance costs needed to keep this inventory in the shape it's in. As it gets older it requires more maintenance. So it's not just the volume, meaning the number of square metres of space; it's the volume of dollars required to keep that space at its current level of standard.
