Property, Plant and Equipment [Abstract]

Property and EquipmentProperty and equipment are stated at cost or, if obtained through acquisition, at fair value determined on the date of acquisition. Depreciation is recognized using the straight-line method over the estimated useful lives of the assets, generally 20 to 40 years for buildings

and building improvements, three to five years for computers and software and five to seven years for furniture and equipment. Leasehold improvements are depreciated on a straight-line basis over the shorter of the lease term or the estimated useful life of the assets. Routine maintenance and repairs are expensed as incurred, while expenditures that increase capacities or extend useful lives are capitalized.

The Company also leases certain facilities and equipment under finance leases. Assets held under finance leases are stated at the present value of lease payments at the inception of the related lease. Such assets are amortized on a straight-line basis over the lesser of the lease term or the remaining useful life of the leased asset.
