| 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’s fixed asset base is old or new. Newer assets are likely to be more efficient. | AT&T Inc.’s average age ratio of depreciable property, plant and equipment deteriorated from 2017 to 2018 and from 2018 to 2019. |
| Estimated total useful life | Over longer time periods, this ratio is a useful measure of company’s depreciation policy and can be used for comparisons with competitors. | AT&T Inc.’s estimated total useful life of depreciable property, plant and equipment increased from 2017 to 2018 but then slightly decreased from 2018 to 2019. |
| Estimated time elapsed since purchase | The approximate age in years of a company’s fixed assets. Useful for comparison purposes. | AT&T Inc.’s estimated time elapsed since purchase of depreciable property, plant and equipment deteriorated from 2017 to 2018 and from 2018 to 2019. |
