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 condensed consolidated statements of income as tenant expense reimbursement.
