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.	Abiomed Inc. average age ratio of depreciable property, plant and equipment deteriorated from 2020 to 2021 and from 2021 to 2022.
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.	Abiomed Inc. estimated total useful life of depreciable property, plant and equipment increased from 2020 to 2021 but then slightly decreased from 2021 to 2022.
Estimated time elapsed since purchase	The approximate age in years of a company fixed assets. Useful for comparison purposes.	Abiomed Inc. estimated time elapsed since purchase of depreciable property, plant and equipment deteriorated from 2020 to 2021 and from 2021 to 2022.
Estimated remaining life		Abiomed Inc. estimated remaining life of depreciable property, plant and equipment increased from 2020 to 2021 but then decreased significantly from 2021 to 2022.

2022 Calculations

¹ Average age = 100 × Accumulated depreciation ÷ (Property and equipment, cost – Land)
= 100 × 102,062 ÷ (304,552 – 10,643) = 34.73%
