Leases

We lease office, retail and storage space to tenants under operating leases. These leases provide for the payment of fixed minimum rents over the terms of the respective lease and generally require tenants to reimburse us for operating costs and real estate taxes above their base year costs.

The following is a schedule of future minimum rents under non-cancelable operating leases as of December 31, 2015.
