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

2023 Calculations

¹ Average age = 100 × Accumulated depreciation ÷ (Property and equipment, gross – Land)
= 100 × 944,068 ÷ (1,501,329 – 21,598) = 63.80%
