Depreciation expense has been computed principally by the straight-line method based on the estimated useful lives of the depreciable assets which are generally as follows:
Category
Useful Life (in years)
Machinery and equipment
2-5
Capitalized software
3-5
Office furniture and equipment
1-5
Leasehold improvements
Life of lease a
Construction in progressN/A
a. Leasehold improvements are amortized on a straight-line basis over the shorter of (i) their estimated useful life or (ii) the estimated or contractual life of the related lease.
Property and equipment at December 31, 2025 and 2024 are summarized as follows:

a. The impairment charges subsequently discussed resulted in the establishment of a new cost basis for certain assets reflected in the table. Gross asset carrying values and accumulated depreciation and amortization have been adjusted to reflect the new cost basis of assets for which the carrying value was reduced due to impairment.

About PP&E Disclosures

The PP&E disclosure details a company's physical asset base — land, buildings, machinery, and equipment — along with the depreciation methods and useful life assumptions that determine how these costs flow through the income statement. Capitalization policy thresholds reveal management's judgment on the boundary between expense and asset, directly affecting both reported earnings and asset values.

Key signals: changes in estimated useful lives or depreciation methods can materially shift reported earnings without any operational change. Compare capital expenditures against depreciation expense — when capex consistently trails depreciation, the asset base may be aging and underinvested. Watch for large asset impairments or write-downs that signal overvalued carrying amounts. Asset retirement obligations reveal future environmental or decommissioning costs that are often underappreciated. Compare PP&E intensity (PP&E-to-revenue) against industry peers to assess capital efficiency and competitive positioning.
