Property and Equipment

8. Property and Equipment

Property and equipment are stated at cost. Repairs and maintenance are charged to expense when incurred.

Property and equipment are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.

Depreciation on property and equipment is calculated using the straight-line method over the estimated useful lives of the assets, generally ranging from two to seven years. Leasehold improvements are amortized using the straight-line method over the shorter of the estimated useful life or the lease term.
