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.	KLA Corp. average age ratio of depreciable property, plant and equipment improved from 2022 to 2023 but then deteriorated significantly from 2023 to 2024.
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.	KLA Corp. estimated total useful life of depreciable property, plant and equipment decreased from 2022 to 2023 and from 2023 to 2024.
Estimated time elapsed since purchase	The approximate age in years of a company fixed assets. Useful for comparison purposes.	KLA Corp. estimated time elapsed since purchase of depreciable property, plant and equipment improved from 2022 to 2023 and from 2023 to 2024.
Estimated remaining life		KLA Corp. estimated remaining life of depreciable property, plant and equipment decreased from 2022 to 2023 and from 2023 to 2024.

2024 Calculations

¹ Average age = 100 × Accumulated depreciation ÷ (Land, property and equipment, gross – Land)
= 100 × 1,284,490 ÷ (2,394,458 – 78,260) = 55.46%
