The useful lives used in computing straight-line depreciation are based on estimated service lives for classes of property, as follows:
 Years
Buildings and improvements
5 to 40
Machinery and equipment
3 to 11
Effective April 1, 2025, the Company implemented a new class of asset, fully dedicated machinery and equipment, which is depreciated using the units of production method. As of June 30, 2025, the net book value of the equipment was $15.3 million. This equipment is highly customized for specific customer programs and has substantially no value other than production for that program. The units of production method more accurately reflects the pattern of usage and expected benefits of these assets than other depreciation methods.

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.
