Allergan PLC (AGN)

Property, plant and equipment are stated at cost, less accumulated depreciation. Major renewals and improvements are capitalized, while routine maintenance and repairs are expensed as incurred. Allergan capitalizes interest on qualified construction projects. At the time property, plant and equipment are retired from service, the cost and accumulated depreciation is removed from the respective accounts.

Depreciation expense is computed principally on the straight-line method, over the estimated useful lives of the related assets. The following table provides the range of estimated useful lives used for each asset type:

Computer software/hardware (including internally developed)	3-10 years
Machinery and equipment	3-15 years
Research and laboratory equipment	3-10 years
Furniture and fixtures	3-10 years
Buildings, improvements, leasehold improvements and other	4-50 years
Transportation equipment	3-20 years

Allergan assesses property, plant and equipment for impairment whenever events or changes in circumstances indicate that an asset's carrying amount may not be recoverable.

Ratio	Description	The company
Average age	As long as straight-line depreciation is used, this is an accurate estimate of asset age as a percentage of depreciable life. The relative age is a useful measure of whether the company's fixed asset base is old or new. Newer assets are likely to be more efficient.	Allergan PLC's average age of depreciable property, plant and equipment improved from 2015 to 2016 but then slightly deteriorated from 2016 to 2017 not reaching 2015 level.
Estimated total useful life	Over longer time periods, this ratio is a useful measure of company's depreciation policy and can be used for comparisons with competitors.	Allergan PLC's estimated total useful life of depreciable property, plant and equipment declined from 2015 to 2016 but then slightly increased from 2016 to 2017.
Estimated time elapsed since purchase	The approximate age in years of a company's fixed assets. Useful for comparison purposes.	Allergan PLC's estimated time elapsed since purchase of depreciable property, plant and equipment improved from 2015 to 2016 but then slightly deteriorated from 2016 to 2017.
Estimated remaining life		Allergan PLC's estimated remaining life of depreciable property, plant and equipment declined from 2015 to 2016 but then slightly increased from 2016 to 2017.
