Understanding Goodwill Impairment Under Ind AS 36
Goodwill impairment is one of those topics that seems complex until you see the logic underneath. As a CA Final student, you'll meet it in both Advanced Accounting and Accounting Standards papers—and examiners love to test whether you truly understand when and how an impairment loss arises.
The core principle is simple: goodwill is an intangible asset that doesn't generate cash itself. Its value depends on the cash flows of the business (or part of the business) that it relates to. When those cash flows weaken, goodwill loses value. Ind AS 36 (Impairment of Assets) gives us a systematic way to test and measure that loss.
Why Goodwill Impairment Matters
Unlike tangible assets (a factory, a truck), goodwill has no physical existence. You can't repair it or replace its components. Its value lives or dies with the profitability of the unit that generates the cash it represents. This is why impairment testing for goodwill is mandatory every year, even if there's no sign of trouble.
Examiners test this topic because:
- It requires judgment (not just formula application)
- It touches on fair values, present values, and business assumptions
- A single mistake in identifying the Cash-Generating Unit (CGU) can derail your entire answer
The Goodwill Impairment Process: Step by Step
Step 1: Identify the Cash-Generating Unit (CGU)
A CGU is the smallest identifiable group of assets that generates cash inflows largely independent of other units. This is the most critical decision in impairment testing.
Key principle: Goodwill acquired in a business combination must be allocated to the CGU (or group of CGUs) expected to benefit from the synergies of the combination.
Common scenarios:
- A company acquires a subsidiary. The entire subsidiary is one CGU if its cash flows are not separable from other parts of the group.
- A company acquires a product line. That product line is a CGU if it has separate, identifiable cash flows.
- A holding company buys a factory that produces goods sold through the parent's distribution network. The factory alone is not a CGU—you must include the distribution network in the CGU.
Exam red flag: Examiners often describe a business structure, then ask you to identify "the appropriate CGU." Many students get this wrong because they don't think about cash flow independence. If revenues, costs, and reinvestment decisions for one part of the business are driven by another, they're one CGU, not two.
Step 2: Calculate the Carrying Amount of the CGU
Add up:
- All identifiable assets in the CGU (tangible, intangible, current assets—everything)
- Plus the goodwill allocated to the CGU
- Minus liabilities
If the CGU includes assets shared with other units (a head office building, for example), allocate them on a reasonable basis (floor area, headcount, usage hours).
Step 3: Determine the Recoverable Amount
The recoverable amount is the higher of:
a) Fair Value Less Costs of Disposal (FVLCD)
- The price you'd get if you sold the entire CGU today
- Minus selling costs (professional fees, legal, agent commissions)
- Based on market conditions at the testing date
b) Value in Use (VIU)
- The present value of cash flows the CGU is expected to generate over its remaining life
In practice, examiners usually ask you to calculate VIU, because fair value data for a whole business unit is rarely available.
Step 4: Value in Use Calculation
Project the CGU's cash flows (usually free cash flows—operating cash flow minus capital expenditure) for a forecast period (typically 5 years, verify latest guidance). Then:
- Sum the present value of forecast-period cash flows using a risk-appropriate discount rate
- Add the present value of terminal value (the value of cash flows beyond the forecast period)
- Terminal value = Final year cash flow × (1 + stable growth rate) ÷ (Discount rate − Growth rate)
- Keep the stable growth rate conservative (often 0–2%)
- Discount everything to today using the discount rate
The discount rate is critical. It reflects the time value of money and the risk of the CGU. Common approaches:
- Weighted average cost of capital (WACC) of the business or CGU
- Pre-tax or post-tax? Use pre-tax if your cash flows are pre-tax; post-tax if post-tax
Step 5: Compare and Recognize Impairment
If Recoverable Amount > Carrying Amount: No impairment. Goodwill is not written down.
If Recoverable Amount < Carrying Amount: Impairment loss = Carrying Amount − Recoverable Amount
Where to record the loss:
- First, write down goodwill to zero (if necessary)
- Then, write down other assets in the CGU on a pro-rata basis (unless a specific asset has an indicator of impairment)
Common Exam Red Flags and Pitfalls
Mistake 1: Wrong CGU Boundary
Flag: You've identified a CGU that's too narrow or too broad.
If you include unrelated cash flows or exclude dependent flows, your recoverable amount will be wrong, and your impairment conclusion will fail.
Fix: Draw a diagram showing which assets' cash flows move together. Goodwill sits in the smallest such group.
Mistake 2: Ignoring Shared Assets
Flag: You include the goodwill and one product line, but ignore the shared central IT team that supports three product lines.
The CGU must include an appropriate share of shared assets. If you omit them, the carrying amount is understated, and you may miss an impairment.
Mistake 3: Cash Flow Forecast Errors
Flag: Projecting cash flows without reasoning, or using growth rates that contradict the scenario.
Always show why your forecast makes sense (new contracts, market trends, cost pressures). Examiners read the working notes.
Mistake 4: Terminal Value Blunders
Flag: Using an unrealistic perpetual growth rate (e.g., 5% or 10%).
Stable growth should not exceed long-term GDP growth. Verify the latest Ind AS 36 guidance on this assumption.
Mistake 5: Forgetting the Allocation to Other Assets
Flag: You calculate an impairment loss but only write down goodwill.
Goodwill gets priority for impairment write-down, but other assets in the CGU must also be reduced if the impairment loss exceeds the goodwill balance.
A Worked Example: The Concept
Company X acquires Division Y for ₹100 crore goodwill. Division Y comprises:
- Factories and equipment: ₹50 crore
- Inventory: ₹20 crore
- Brand (allocated): ₹15 crore
- Net working capital: ₹10 crore
- Less: Debt: (₹20 crore)
Carrying amount of CGU = 50 + 20 + 15 + 10 − 20 + 100 (goodwill) = ₹175 crore
You forecast 5-year cash flows and terminal value. When discounted at 10%, the VIU = ₹150 crore.
No fair value data, so Recoverable Amount = ₹150 crore.
Impairment loss = 175 − 150 = ₹25 crore
This is charged first against goodwill (₹100 crore available), so:
- Goodwill is written down by ₹25 crore → ₹75 crore
- No impairment to other assets
FAQs
Q1: Must I test goodwill every year?
A: Yes, under Ind AS 36, goodwill impairment testing is mandatory annually, even if there are no signs of impairment. However, if you have a "rebuttable presumption" that the asset can be carried at its historical cost with no impairment, you might reduce testing frequency—verify the latest ICAI guidance on this.
Q2: Can I use the parent company's discount rate for a subsidiary's VIU?
A: Not always. If the subsidiary operates in a different market or has different risks, it should have its own discount rate. The WACC approach should reflect the CGU's specific risk profile. Examiners often test whether you adjust for subsidiary-level risk.
Q3: What if a CGU contains both goodwill from an acquisition and goodwill from internal generation?
A: Only acquired goodwill is tested for impairment under Ind AS 36. Internally generated goodwill is not capitalized. If the acquired goodwill is in a CGU that also contains unrelated assets, allocate shared costs appropriately and identify the correct CGU boundary.
