Property, Plant and Equipment [Abstract]

Property, plant, and equipment are recorded at cost, net of accumulated depreciation and impairments. Costs of routine maintenance and repair are expensed when incurred.

The Company capitalizes certain qualified costs incurred in connection with the development of software used internally. Costs incurred during the application development stage are evaluated to determine whether the costs meet the criteria for capitalization. Costs related to preliminary project activities and post implementation activities that are not incremental upgrades, including maintenance, are expensed as incurred.

Property, plant, and equipment are primarily depreciated using the straight-line method over the estimated useful life of the asset. Land is not depreciated.
