Property and equipment are stated at cost. We compute depreciation using straight-line method over a range of estimated useful lives from 3 to 30 years. We amortize leasehold improvements on a straight-line basis over the shorter of their estimated useful lives or the underlying lease term. Repair and maintenance costs are charged to operations as incurred. Depreciation expense for continuing operations was $268 and $750 for fiscal years 2018 and 2017, respectively. During 2018, property and equipment with a net book value of $54 was sold resulting in a gain on sale of $5.
