Mr. Chair, in a point of correction, if I may, we have 2,000 leases in place, all expiring at different periods, so they're not all coming up. They will over time. As I said, some might run 25 years.
In terms of the lease agreements themselves, we pay a fixed amount for the rent, which is stipulated in the lease. There are other aspects of the lease that are conveyed to us as a pass-through cost in terms of utilities, electrical, and what we pay in municipal taxes. As those increase or change over time, we seek to have those funds conveyed to us through estimates such as these.
