Asset age ratio	Description	The company
Average age ratio	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 fixed asset base is old or new. Newer assets are likely to be more efficient.	Zoetis Inc. average age ratio of depreciable property, plant and equipment improved from 2019 to 2020 and from 2020 to 2021.
Estimated total useful life	Over longer time periods, this ratio is a useful measure of company depreciation policy and can be used for comparisons with competitors.	Zoetis Inc. estimated total useful life of depreciable property, plant and equipment decreased from 2019 to 2020 and from 2020 to 2021.
Estimated time elapsed since purchase	The approximate age in years of a company fixed assets. Useful for comparison purposes.	Zoetis Inc. estimated time elapsed since purchase of depreciable property, plant and equipment improved from 2019 to 2020 and from 2020 to 2021.

Asset Age Ratio
Average age¹	46.33%	47.24%	47.52%	49.43%	51.01%

2021 Calculations

¹ Average age = 100 × Accumulated depreciation ÷ (Property, plant and equipment, gross carrying amount – Land)
= 100 × 2,072 ÷ (4,494 – 22) = 46.33%
