Non-Current Assets: The Useful Life Is a Guess
Non-current assets are the resources a company expects to hold for more than twelve months, carried at cost less accumulated depreciation. The useful life over which they are depreciated is an estimate made by the company, and changing it changes reported profit directly.
How it works
Buildings, machinery, vehicles, software, purchased intangibles and goodwill. Anything the company intends to use rather than sell, over a period longer than a year.
They are carried at cost and written down over their estimated useful life. That annual write-down is depreciation for physical assets and amortisation for intangibles, and it is an allocation rather than a payment — the money left when the asset was bought.
The estimate that moves profit
A machine costing 2,000 depreciated over ten years charges 200 a year. Over fifteen years it charges 133. Same machine, same cost, 67 more profit reported annually — from a change in an estimate.
Useful lives are disclosed in the accounting policies and are occasionally revised. A revision is legitimate and it is also a lever, and the direction is always the same: extending lives raises reported profit immediately.
This is the single most checkable soft spot in a set of accounts, because the policy note states the lives and a change has to be disclosed.
That same charge is what EBITDA adds back. Which is why the comparison worth making is depreciation against capital spending on the cash flow statement: if capital spending is persistently larger, the add-back is describing money that has to be spent anyway.
Maintenance capital spending is the part that buys nothing new. Growth spending adds capacity; maintenance keeps what exists working. Companies rarely split them, and the split is the difference between a business that generates cash and one that recycles it.
What is missing from the page
Internally generated intangibles are generally not capitalised. A company that spent twenty years building a brand carries nothing for it; a company that bought that brand carries the price it paid. The same economic asset, two completely different balance sheets.
Which is a large part of why book value and market value diverge, and why the divergence is largest in businesses whose value is mostly things accounting does not record.
Leases were moved onto the balance sheet by accounting changes taking effect from 2019. A leased building now appears as a right-of-use asset with a matching liability, where previously it was a rental expense and a note. Comparisons spanning that change need care.
In practice
Operating income divided by these assets is the return the company earns on what it has invested. It is the closest single figure to “is this a good business,” and it is comparable across years for the same company even when the accounting conventions make cross-company comparison awkward.
And acting on any of it in the market costs 2% of a median bar’s range per round trip on this site’s shared price history.
Run the depreciation check on numbers and it takes one line. A company charges 45 of depreciation and spends 70 on capital expenditure, every year, for five years. Over that period it charged 225 as a cost and spent 350 in cash — a gap of 125 that never appeared on the income statement as an expense.
That gap is the difference between reported profit and what the business actually costs to run. It is not fraud and it is not unusual: depreciation is based on historical cost, and replacement happens at today’s prices. In a period of rising costs, depreciation systematically understates what maintaining the asset base requires, and the only place to see it is the two numbers side by side.
What non-current assets are not
They are not market value. Cost less depreciation is the general rule.
They are not the company’s real productive base. What it built itself is largely absent.
They are not permanent. Impairment can remove a large portion in one charge.
And they are not comparable across companies with different accounting policies without reading those policies.
When it fails
An impairment is the accounting system correcting itself, usually late and usually all at once. The asset was carried at a value that could not be supported, sometimes for years, and the write-down is the admission rather than the event.
The second failure is the useful-life revision. Profit improves, no cash changes hands, and the explanation is in a policy note rather than in the results announcement.
A third is treating depreciation as fake because it is non-cash. The asset wears out. The cash was spent earlier or will be spent again.
A fourth is missing maintenance spending. A company whose capital spending consistently exceeds its depreciation is more capital-hungry than the income statement suggests.
And a fifth is comparing across the lease accounting change without adjusting, which makes a company look as though it took on debt in 2019 when it merely started reporting obligations it already had.
The original data
Of the 31,760 trading and investing videos in this site’s corpus, 0 have “EBITDA” in the title — the
measure whose entire purpose is adding this depreciation back. “Balance sheet” returns 3 videos at a
median of 23,862 views and “cash flow” returns 17 at a median of 67,134. The counts are in
research/corpus-coverage.json, produced by site/measure_corpus.py.
Zero videos on the measure built by removing the charge this page is about. That absence is worth naming because the add-back is not a technicality — it is the difference between a business that generates cash and one that spends everything it makes on staying operational. The two-line check that settles it is depreciation against capital spending, five years side by side, and it is available in every annual report and suggested by almost nothing anyone will show you.

Assets is the full total this is part of. Balance sheet is the page it sits on. And EBITDA is the measure that removes the depreciation charged here.
The check I run is depreciation against capital spending, every year, for five years. If the company is consistently spending more to maintain its assets than it charges as depreciation, the depreciation number is understating what the business really costs to run.
