Analysis of Property, Plant and Equipment
Advanced level
Accounting Policy on Property, Plant and Equipment
Property, plant and equipment are depreciated over the estimated useful lives of individual assets. Most assets are depreciated using declining-balance methods, with the remainder using the straight-line method. Depreciation expense is generally recorded in the same segment where the related assets are held. However, the additional depreciation expense related to the step-up in fair value of property, plant and equipment acquired through business combinations is recorded in unallocated corporate expense within operating income as such depreciation is not considered part of management’s evaluation of segment operating performance. Major classes of property, plant and equipment and their useful lives are as follows:
| Useful life in years | Useful Life |
| Land and land improvements | Up to 40(1) |
| Buildings and improvements | Up to 40 |
| Machinery and other equipment | Up to 20 |
| Capitalized software costs | 3-5 |
| Leasehold improvements | Length of Lease(2) |
(1) Land is not a depreciable asset.
(2) Leasehold improvements are depreciated over the shorter of the useful life of the asset or the length of the lease.
