NET PROPERTY

Net property is reported at cost, net of accumulated depreciation, which includes impairments.  We capitalize new assets when we expect to use the asset for more than one year.  Routine maintenance and repair costs are expensed when incurred.

Property and equipment are depreciated primarily using the straight-line method over the estimated useful life of the asset.  Useful lives range from 3 years to 40 years.  The estimated useful lives generally are 14.5 years for machinery and equipment, 8 years for software, 30 years for land improvements, and 40 years for buildings.  Tooling generally is amortized over the expected life of a product program using a straight-line method.
