Leases [Abstract] |
Rental Income | Rental Income We lease various office spaces to tenants over terms ranging from one to 16 years. Certain leases have renewal options for additional terms. The leases provide for base monthly rentals and reimbursements for real estate taxes, escalations linked to the consumer price index or common area maintenance known as operating expense escalation. Operating expense reimbursements are reflected in our consolidated statements of operations as tenant expense reimbursement. As of December 31, 2016, we were entitled to the following future contractual minimum lease payments on non-cancellable operating leases to be received which expire on various dates through 2032 (amounts in thousands):
2017 |  |  | $ | 453,715 |
2018 |  |  | 426,589 |
2019 |  |  | 393,269 |
2020 |  |  | 354,588 |
2021 |  |  | 316,917 |
Thereafter |  |  | 1,471,708 |
|  |  | $ | 3,416,786 |
The above future minimum lease payments exclude tenant recoveries, amortization of deferred rent receivables and the net accretion of above-below-market lease intangibles. Some leases are subject to termination options generally upon payment of a termination fee. The preceding table is prepared assuming such options are not exercised.
