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.	Lam Research Corp. average age ratio of depreciable property, plant and equipment improved from 2021 to 2022 but then slightly deteriorated from 2022 to 2023.
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.	Lam Research Corp. estimated total useful life of depreciable property, plant and equipment increased from 2021 to 2022 but then slightly decreased from 2022 to 2023.
Estimated time elapsed since purchase	The approximate age in years of a company fixed assets. Useful for comparison purposes.	Lam Research Corp. estimated time elapsed since purchase of depreciable property, plant and equipment deteriorated from 2021 to 2022 and from 2022 to 2023.
Estimated remaining life		Lam Research Corp. estimated remaining life of depreciable property, plant and equipment increased from 2021 to 2022 but then slightly decreased from 2022 to 2023.

2023 Calculations

¹ Average age = 100 × Accumulated depreciation and amortization, excluding finance right-of-use assets ÷ (Property and equipment, gross, excluding finance right-of-use assets – Land)
= 100 × 1,642,456 ÷ (3,445,407 – 98,739) = 49.08%
