(1)The book value of our net real estate assets is in excess of tax basis by approximately $183.1 million at December 31, 2020.
(2)Encumbrances do not include $5.3 million of non-cash debt related items and $(.8) million of deferred debt costs.

Depreciation is computed using the straight-line method, generally over estimated useful lives of 18-40 years for buildings and 10-20 years for parking lot surfacing and equipment. Tenant and leasehold improvements are depreciated over the remaining life of the lease or the useful life whichever is shorter.
