We lease space to tenants under operating leases that expire at various dates through the year 2036. The leases provide for the payment of fixed base rents payable monthly in advance as well as reimbursements of real estate taxes, insurance and maintenance costs. Retail leases may also provide for the payment by the lessee of additional rents based on a percentage of their sales. As of December 31, 2017, future base rental revenue under these non-cancelable operating leases excluding extension options is as follows:
