Goodwill & Impairment

Why a company can pay ₹1,000 crore to buy a business worth ₹600 crore on paper — and how accountants decide, every year after, whether that extra ₹400 crore was money well spent.

In plain English

Imagine a large company buys a smaller, fast-growing brand for ₹1,000 crore. If you added up the actual identifiable things the brand owns — its factory, its inventory, its trademarks, its cash, minus its debts — you'd only get to about ₹600 crore. So why did the buyer pay ₹1,000 crore?

Because a business is worth more than the sum of its identifiable parts. The buyer is paying for the brand's loyal customers, its talented team, its market position, the extra revenue it expects the two companies to generate together that neither could alone — things that are real and valuable, but that can't be tagged and valued individually the way a factory or a trademark can. Accountants have a name for this unexplained extra: Goodwill. It isn't a made-up number — it is simply 'purchase price minus the value of everything that could be separately identified and valued.'

Goodwill accounting is really about two separate questions: first, how is that number calculated on the day of the purchase? And second — the much bigger, more consequential question — how does anyone keep checking, year after year, whether that goodwill is still worth what was paid for it?

Words you'll need first

Purchase Price Allocation (PPA)

When one company buys another, accountants don't just record 'we paid ₹1,000 crore for a company.' They go through the acquired business piece by piece and assign a fair value to everything they can identify separately — buildings, machinery, inventory, trademarks, customer contracts, patents — right down to specific line items. Whatever is left over, after adding up all those identified pieces and subtracting the acquired company's liabilities, is Goodwill. This exercise is called Purchase Price Allocation, and it's why goodwill is sometimes described as a 'plug' or a residual — it's whatever doesn't fit anywhere else.

Cash Generating Unit (CGU)

Goodwill doesn't generate cash on its own — a brand name alone doesn't produce revenue, the actual business built around it does. So instead of testing goodwill in isolation, accountants group it with the smallest identifiable cluster of assets that DOES generate its own independent cash flows — this cluster is a Cash Generating Unit. Think of a conglomerate that owns a paints business and a chemicals business: even if goodwill from an old acquisition sits on the group's books, it gets tested for impairment at the level of whichever CGU it actually belongs to, using that unit's own future cash flow projections, not the whole conglomerate's.

Value in Use

The estimated present value of all the future cash a Cash Generating Unit is expected to generate, discounted back to today — very similar in spirit to how a Lease Liability is calculated by discounting future rent payments. If a CGU's Value in Use (or what it could be sold for, whichever is higher — its 'recoverable amount') falls below the value of its assets, including the goodwill allocated to it, as currently shown on the balance sheet, that gap is exactly how much the goodwill has to be written down.

Before vs. now

How it used to happen

For a long time, the dominant approach — under older Indian GAAP and, until 2001, under US GAAP too — was to treat goodwill like any other intangible asset: spread its cost over an assumed useful life, often 5 to 20 years, and charge a slice of it to the P&L as amortisation expense every year, whether or not the acquired business was actually doing well. A company that badly overpaid for an acquisition, and a company that got a brilliant bargain, would show an identical amortisation charge each year as long as the goodwill amount and assumed life were the same — the expense told you almost nothing about whether the deal had actually worked out.

How it's done now

Global standard-setters scrapped this in the early-to-mid 2000s (the US moved first, in 2001; IFRS, and later Ind AS, followed) in favour of an impairment-only model. Goodwill is no longer amortised at all — it sits on the balance sheet at its original value indefinitely. Instead, at least once a year, and more often if there's reason to suspect trouble (a profit warning, a lost major customer, a sharp industry downturn), the company must formally test whether the Cash Generating Unit the goodwill belongs to is still worth at least as much as it's carried on the books. If it isn't, the goodwill is written down immediately, in full, through the P&L — there's no smoothing it out over several years the way amortisation used to.

A worked example, with numbers

Suppose a company acquires a smaller business for ₹1,000 crore. Purchase Price Allocation values the identifiable net assets (factory, trademarks, inventory, minus debts) at ₹600 crore, so ₹400 crore is recorded as Goodwill on day one. Three years later, the acquired business's performance has disappointed — competition intensified and growth stalled — so the company runs its annual impairment test on the Cash Generating Unit.
Item₹ crore
Carrying value of the CGU's net assets (excl. goodwill)550
Carrying value of Goodwill allocated to this CGU400
Total carrying value being tested950
Recoverable amount (higher of Value in Use and fair value less costs to sell)700
Impairment loss (carrying value − recoverable amount)250
  • The ₹250 crore impairment loss is charged first against Goodwill, since accounting rules require goodwill to absorb the hit before other assets in the same CGU — so Goodwill drops from ₹400 crore to ₹150 crore, and the P&L takes a one-time ₹250 crore hit, usually shown as a separate 'exceptional' or 'impairment' line.
  • Unlike depreciation or amortisation, which are spread evenly over years and are fairly predictable, an impairment charge shows up suddenly, all at once, in the year the test fails — which is exactly why big goodwill write-downs often blindside investors and cause a sharp one-day drop in reported profit, even though the cash was actually spent years earlier, at the time of acquisition.
  • Impairment can only ever reduce goodwill — unlike some other assets, goodwill can never be written back up again later even if the acquired business recovers strongly. Once it's written down, it's written down for good.

What it does to the financial statements

Impact on the P&L

  • There is no routine annual amortisation charge for goodwill anymore — in a normal year, with no impairment, goodwill has zero impact on the P&L at all.
  • When an impairment test fails, the entire shortfall is charged to the P&L immediately as a one-off expense, usually shown as a separate exceptional item below operating profit — large enough, at times, to turn a profitable year into a reported loss.
  • Because impairment charges are lumpy and unpredictable, unlike smooth annual amortisation, analysts often exclude them when judging a company's 'underlying' or 'adjusted' performance — but a pattern of repeated impairments is a real signal that a company's acquisitions haven't paid off.
  • An impairment charge is a non-cash expense — no money leaves the company on the day it's booked, since the cash went out years earlier when the acquisition was actually paid for — but it still reduces reported net profit and earnings per share.

Impact on the Balance Sheet

  • Goodwill sits under non-current (intangible) assets on the balance sheet, generally at its original value, unless and until an impairment write-down reduces it — it is never routinely reduced through amortisation the way most other intangible assets are.
  • An impairment charge directly shrinks total assets and, through the matching hit to retained earnings, shrinks shareholders' equity by the same amount.
  • Because equity shrinks while liabilities generally don't, a goodwill write-down mechanically pushes up Debt/Equity and other leverage ratios, even though the company hasn't borrowed a single extra rupee.
  • A company with a very high proportion of Goodwill and other intangibles relative to its total assets is inherently more exposed to a sudden, large write-down if the underlying acquired businesses underperform — worth checking before investing in a serially-acquisitive company.

Which standard covers this

In India, the CREATION of goodwill, at the time of an acquisition, is governed by Ind AS 103 – Business Combinations, while its ongoing TESTING for impairment is governed by Ind AS 36 – Impairment of Assets, both notified under the Companies (Indian Accounting Standards) Rules and applicable to companies that follow Ind AS.

How it's recognised globally

Globally, the equivalent standards are IFRS 3 (business combinations) and IAS 36 (impairment) — Ind AS 103 and Ind AS 36 are closely aligned with them, and both work on the same impairment-only model described above. The United States uses its own standard, ASC 350, under US GAAP, which also uses an impairment-only approach for public companies, broadly similar in spirit — though the detailed mechanics of the impairment test (how a 'reporting unit', the US GAAP near-equivalent of a Cash Generating Unit, is defined, and a 2014 rule that lets PRIVATE companies elect to amortise goodwill over 10 years instead of testing it for impairment) differ enough in the fine print that the exact impairment amount and timing can genuinely differ between an Indian/IFRS filer and a US filer holding economically similar goodwill.

Real example — Indian listed company

Tata Motors — Jaguar Land Rover

India's most dramatic real-world example of this mechanism playing out is Tata Motors and Jaguar Land Rover (JLR), the British luxury car business Tata Motors bought in 2008. By late 2018, JLR was struggling — sales in China were falling sharply, the industry was being disrupted by the shift toward electric vehicles, and the cost of funding the business had risen. Tata Motors' accountants ran the impairment test described in this article on the JLR Cash Generating Unit, projected its future cash flows, and found a large gap between what JLR's assets — including the goodwill and other value built up since the 2008 acquisition — were carried at on the books, and what they were realistically worth going forward. The result: an impairment charge of about ₹27,838 crore (roughly £3.1 billion) taken in a single quarter (October–December 2018) — at the time, the single biggest quarterly loss ever reported by an Indian company, pushing Tata Motors to a consolidated net loss of about ₹26,961 crore for that quarter alone, and around ₹28,826 crore for the full financial year 2018-19. Two things are worth noticing, both explained earlier in this article: first, this was a non-cash charge — no money left Tata Motors that quarter because of this entry, since the cash had already been spent a decade earlier acquiring JLR — but it still wiped out reported profit for the year. Second, this specific impairment covered JLR's assets more broadly, not goodwill in isolation, which is exactly how the standard is meant to work: goodwill is tested together with the rest of the Cash Generating Unit it belongs to, not on its own.
