Property, Plant and Equipment

Property, plant and equipment are stated at cost less accumulated depreciation. Depreciation is applied using a straight-line method over the useful lives of the respective assets as described in the following table:

 Estimated Useful Life
Land improvements20 years
Buildings45 years
Machinery and equipment3-20 years
Tooling — Airplane program — B787, Rolls-Royce5-20 years
Tooling — Airplane program — all others2-10 years
Capitalized software3-7 years

The Company capitalizes certain costs, such as software coding, installation, and testing, that are incurred to purchase or to create and implement internal-use computer software. The Company’s capitalization policy includes specifications that the software must have a service life greater than one year, is legally and substantially owned by the Company, and has an acquisition cost of greater than $0.1. The Company applies the same criteria for capitalizing implementation costs incurred in a cloud computing arrangement hosted by the vendor.

Where the Company is involved in build-to-suit leasing arrangements, the Company is deemed the owner of the asset for accounting purposes during the construction period of the asset. The Company records the related assets and liabilities for construction costs incurred under these build-to-suit leasing arrangements during the construction period. Upon completion of the asset, the Company considers whether the assets and liabilities qualify for derecognition under the sale-leaseback accounting guidance. See Note 10, Property, Plant and Equipment, net.
