Depreciation, amortisation and capitalisation - the quietest lever on profit

A telecom company spends ₹6,000 crore upgrading its network. The cash leaves - the cheques are written, the equipment is installed. Now the finance team faces a choice the cash has already settled but the accounts have not. Is that ₹6,000 crore a cost of this year, charged in full against this year's profit? Or is it an asset the company now owns and will use for a decade, charged against profit a little at a time - ₹600 crore a year for ten years? illustrative

The cash is identical either way. The reported profit is not. Charge the whole ₹6,000 crore now and a ₹3,000 crore profit becomes a ₹3,000 crore loss. Spread it over ten years and this year carries only ₹600 crore, so the company still reports a healthy profit. Same business, same cash, same year - a ₹5,400 crore swing in the bottom line, decided entirely by which of two boxes the spend is written into.

Module 6 established that profit is an opinion. This module takes the single largest of those judgements for an asset-heavy business and shows how it works, because it is the one most often used to make a weak year look strong. It is the quietest lever on reported profit: nothing dramatic happens on the day it is pulled. No sale to point to, no cost that visibly rose or fell. A single estimate changes, and the profit moves with it.

The honest reason the choice exists is sound. A company that buys a machine for ₹100 crore and uses it for ten years has not suffered a ₹100 crore cost in year one - it has bought ten years of use. So accounting puts the machine on the balance sheet as an asset and charges roughly ₹10 crore a year to profit for ten years. That yearly charge is depreciation. The act of putting the spend on the balance sheet rather than expensing it immediately is capitalisation. When the asset is not physical - a software platform, a broadcasting licence, a drug patent, a film library - the same yearly charge is called amortisation, but it does the identical job.

Follow a single ₹6,000 crore spend through the two routes it can take. The cash flow statement records the same ₹6,000 crore leaving either way - that never changes. What changes is the profit-and-loss account.

Expense it now. The whole ₹6,000 crore is a cost of this year and lands on the P&L in full. If the business would otherwise earn ₹3,000 crore before tax, it now reports a ₹3,000 crore loss. Nothing goes on the balance sheet.

Capitalise it. The ₹6,000 crore becomes an asset on the balance sheet, and only a slice - one-tenth if the asset is judged to last ten years - is charged to this year's profit. This year still reports a ₹2,400 crore profit. Next year another ₹600 crore is charged, and the asset drops to ₹5,400 crore, then ₹4,800 crore, until it is fully written off.

The capitalising route borrows profit from the future. The ₹5,400 crore it did not charge this year has not vanished - it will be charged over the next nine years, ₹600 crore at a time. If the asset genuinely earns for those nine years, that is fair: cost matched to the income it produces. If it does not - if the "network enhancement" is really routine maintenance, or the film flops, or the app is abandoned - the company has moved a real cost off this year's profit and parked it on the balance sheet, where it sits until someone forces a reckoning.

That reckoning is impairment. When a capitalised asset can no longer earn back the value it is carried at, the difference must be written down, and the write-down hits profit in the year it is taken. Impairment is the delayed bill for capitalising too eagerly. A balance sheet full of intangibles "under development" is a balance sheet full of costs that have not yet been charged to anyone - and one honest year can bring them all due at once.

So there are three judgement points, each moving profit on its own: whether the spend is capitalised at all; the useful life over which a capitalised cost is spread; and when a capitalised asset is admitted to be worth less than its carrying value. A management wanting a better profit this year can lean on any of the three, and none of them shows on the face of the P&L.

The naive reading is that capitalising is aggressive and expensing is honest. That rule is too simple, and it inverts depending on what the spend actually buys.

The accounting entry is the same in every box - a cost moved from the P&L to the balance sheet - while its honesty runs from plainly correct to plainly aggressive. You cannot judge the choice by the choice. You have to ask what the spend bought and whether that thing will still be earning over the life the company assumed. For telecom the answer is almost always yes. For an early consumer platform capitalising its staff cost the answer is often no, and the same entry that is prudent for the network becomes the tell.

Take the telecom composite. It reports revenue of ₹89,000 crore and EBITDA of ₹39,000 crore - a fat 44% margin that, on that line alone, looks like a wonderful business. Then the two slow charges arrive. Depreciation on the network takes ₹21,000 crore. Amortisation of spectrum - the licence to use the airwaves, an intangible - takes another ₹8,000 crore. Between them they consume three-quarters of the EBITDA, and the 44%-margin machine reports an operating profit of ₹10,000 crore and, after ₹7,000 crore of interest, a pre-tax profit of just ₹3,000 crore. illustrative

For a capex-heavy business, EBITDA and profit live in different worlds, and the distance between them is depreciation and amortisation. A telecom, a cement maker, a utility - each can show a handsome EBITDA margin and a thin bottom line, and the gap is not a trick. It is the real, slow cost of the assets the business runs on.

Now watch the lever. Against that ₹3,000 crore pre-tax profit, the ₹6,000 crore network spend from the opening is enormous. Expense it and the year is a ₹3,000 crore loss; capitalise it over ten years and the year is a ₹2,400 crore profit. The single choice is larger than the entire reported profit of the business. Two telecoms with identical networks and identical cash flows can report very different profits purely because one assumes its equipment lasts eight years and the other twelve - the one assuming twelve reports higher profit every year, right up until its older equipment has to be replaced sooner than its accounts implied.

So whenever a company owns a lot of long-lived assets, find three numbers before you trust its profit. The D&A charge as a share of EBITDA, so you know how much of operating profit is really the slow return of past capex. The assumed useful lives, compared against peers - an outlier life is an outlier profit. And the movement in "capital work in progress" and "intangibles under development", where costs can sit un-charged. None of these is on the face of the P&L; all of them decide what the face of the P&L says.

The tool toggles a spend between "expense now" and "capitalise and depreciate", and draws the trail of future charges. Its presets are the four sectors above - the telecom network, where capitalising is plainly right and the useful life is the live question, and the SaaS development cost, where the identical entry is most often the flatterer. The arithmetic is the same in both; only the honesty changes with the business you point it at.

When profit rises faster than the business seems to justify, a sharp analyst goes looking for the accounting reason, and on an asset-heavy company the first place to look is the depreciation policy. The question sounds like this: "Your depreciation charge fell this year even though gross block went up. Did the useful-life assumptions change, and what was the profit impact?" What the analyst is really asking is whether the profit growth is operational or just a change of estimate.

A good answer names the cause, quantifies it, and strips it out:

"Yes, we reassessed the life of our core network equipment from eight to ten years, based on a technical review showing the kit is lasting longer in the field. The impact was about ₹1,900 crore lower depreciation this year, disclosed in note 3. Stripping that out, underlying profit before tax grew about 6%, not the 30% the headline shows. The new lives are in line with what our equipment vendors quote and with global peers."

The evasive version is not a strawman - it is the fluent, standard-sounding answer real managements give, and every sentence is technically true:

"We periodically review our asset lives in line with the accounting standards and our auditors are fully comfortable with the treatment. Depreciation reflects the useful economic life of the assets. Overall it's been a strong year of profit growth driven by operating leverage across the network."

What makes it evasive is what it omits. It never says the lives were changed, by how much, or what the profit impact was. It waves at "operating leverage" to explain a jump that was partly an estimate, and hides behind the auditor's comfort - which confirms the treatment is permitted, not that the growth is real. The follow-up nobody asks turns the vagueness into a number: "Can you give the exact rupee impact of the life change on this year's profit before tax, and the underlying growth excluding it?" If "we review our lives periodically" is allowed to stand unquantified, the reader is left crediting the business for a profit jump a single estimate delivered. The silence is the tell.

Treating EBITDA as profit. For an asset-heavy business the whole point of the D&A charge is that the assets really do cost money as they wear out and go obsolete. A 44% EBITDA margin is genuine, but it is not the return to shareholders - the network has to be renewed, and D&A is the honest, if slow, admission of that. Anyone who values a capex-heavy company on EBITDA is pretending the assets are free. They are not; they are merely paid for in a different year.

Admiring profit that came from a falling depreciation charge. If a company owns more assets each year, its depreciation should generally rise. When it falls while the asset base grows, the most common cause is a stretched useful life - legal, disclosed, entirely reversible. It flatters every year until the assets wear out faster than the accounts assumed, then reverses in a lump. The face of the P&L never flags it; only the note on depreciation policy, read year over year, does.

Trusting a balance sheet swelling with "intangibles under development" or "capital work in progress". These are the waiting rooms for capitalised cost - a spend parked there is not charged to profit and not yet amortised either. Sometimes that is proper: a plant genuinely being built, a platform genuinely being written. But it is also exactly where this year's running costs hide to protect this year's profit, and the bill arrives later as an impairment. When those lines grow far faster than the business, the question is not "what a lot of investment" but "how much of this is really this year's expense, waiting to come due?"

One caution on the other side. The policy tells you how a company is choosing to report the cost of its assets, not whether the assets are any good, and not the cash story. Depreciation and amortisation are non-cash charges - they lower profit but move no money - which is why the cash flow statement adds them back, and why a company with heavy D&A can be far more cash-generative than its thin profit suggests. The capitalisation choice moves reported profit around; it does not create or destroy a rupee of cash. To judge whether the capex being capitalised is actually earning a return, you still go to the cash flow statement and the return-on-capital modules. And it cannot, by itself, prove intent: a stretched life might be an honest reassessment or a reach for profit. The policy shows the lever was pulled and by how much; good faith you infer from the pattern over several years, from how the lives compare with peers, and from whether the capitalised assets ever turn into the earnings promised for them.
