Why the Allocation Order in Ind AS 36 Matters
Imagine a business unit that owns goodwill, a specialised machine, a building, and some receivables. One year, the recoverable amount of that entire cash-generating unit (CGU) falls below its carrying amount. An impairment loss must be recognised — but which asset absorbs it first? In what proportion? Can any asset's carrying amount fall below zero?
These are exactly the questions that Ind AS 36 answers through a step impairment testing approach. Understanding the allocation sequence is one of the most examiner-favourite topics in CA Intermediate and CA Final Financial Reporting. Let us walk through it carefully.

Quick Recap: What Is a CGU?
A cash-generating unit is the smallest identifiable group of assets that generates cash inflows largely independent of cash inflows from other assets or groups of assets. When you cannot estimate the recoverable amount of a single asset in isolation, you test the CGU as a whole.
The recoverable amount of the CGU = higher of:
- Fair value less costs of disposal (FVLCD), and
- Value in use (VIU)
If carrying amount of the CGU > its recoverable amount → impairment loss = that difference.

The Allocation Sequence — Step by Step
Ind AS 36 lays out a strict priority order for absorbing the impairment loss. Think of it as a waterfall.
Step 1 — Hit Goodwill First
Goodwill allocated to the CGU is always reduced first, down to zero if needed. Why? Because goodwill represents the most intangible, least separable value. It has no independently verifiable fair value in most situations, so the standard treats it as the first cushion.
Worked Logic:
> CGU carrying amount = ₹50 lakh (Goodwill ₹10 L + Machine ₹25 L + Building ₹15 L) > Recoverable amount = ₹38 lakh > Impairment loss = ₹12 lakh > > Step 1 → Reduce goodwill by ₹10 lakh (wipes it out entirely). > Remaining loss = ₹2 lakh — now go to Step 2.
Step 2 — Allocate Remaining Loss Pro-Rata to Other Assets
After goodwill is exhausted, the remaining impairment loss is spread across the other assets of the CGU in proportion to their carrying amounts.
Continuing the example:
> Machine CA = ₹25 L; Building CA = ₹15 L; Total = ₹40 L > Machine absorbs: (25/40) × 2 = ₹1.25 lakh > Building absorbs: (15/40) × 2 = ₹0.75 lakh
Simple enough — but here the allocation problem really begins.

The Three Constraints That Complicate the Allocation
Pro-rata allocation sounds clean, but Ind AS 36 sets firm limits on how low any individual asset's carrying amount can fall:
- It cannot go below fair value less costs of disposal (if determinable).
- It cannot go below value in use (if determinable individually).
- It cannot go below zero (a carrying amount is never negative).
If any asset hits one of these floors before absorbing its full pro-rata share, the excess loss is reallocated to the remaining assets on a pro-rata basis — and the process repeats until the entire impairment loss is absorbed or all other assets have also hit their floors.
Why This Creates an Iterative Problem
Suppose in the example above, the machine has an individual FVLCD of ₹24 lakh. Its carrying amount after the first pro-rata round would be ₹23.75 lakh, which is still above ₹24 lakh? No — ₹25 L − ₹1.25 L = ₹23.75 L, which is below ₹24 L. So the machine can only absorb ₹1 lakh (bringing it to ₹24 L), not ₹1.25 lakh.
The unabsorbed ₹0.25 lakh then falls entirely on the building.
This back-and-forth reallocation is why students must always check the floor before finalising each asset's impairment figure.

What About Corporate Assets?
Some assets — head-office buildings, central IT systems — do not generate independent cash flows. These corporate assets must first be allocated across CGUs (pro-rata by carrying amount or another rational basis), and the impairment test is performed at that higher level. Only if a meaningful allocation is impossible do you test a still-higher group of CGUs.

Reversal of Impairment — The Mirror Rule
Impairment losses can be reversed in later years except for goodwill — goodwill impairment is permanent under Ind AS 36. For other assets, reversal is capped at what the carrying amount would have been had impairment never been recognised (net of subsequent depreciation).

Key Exam Points at a Glance
- Always exhaust goodwill first before touching tangible or other intangible assets.
- Pro-rata allocation is based on carrying amounts of the remaining assets, not original cost.
- Three floors exist: FVLCD, VIU, and zero — whichever is highest sets the floor for each asset.
- Reallocation is iterative — keep going until the loss is fully absorbed or all assets are at floor.
- Goodwill impairment cannot be reversed in a future period.
- Verify exact section references and any revised thresholds in the latest ICAI study material / announcement before your exam.

A Practical Memory Hook
Think of impairment as a leaking water tank inside a CGU. The goodwill bucket drains first. Once empty, the remaining water spreads across the other buckets proportionally — but each bucket has a minimum level marked on it (the floor). If a bucket can only take so much, the overflow goes to the next bucket. The process stops when all the water is absorbed or all buckets are at their marked minimum.

FAQs
Q1. Can a tangible asset's carrying amount become negative after impairment allocation? No. Zero is the absolute floor under Ind AS 36. Any unabsorbed loss beyond that is redistributed to remaining assets that still have room above their own floors.
Q2. What if the CGU has no goodwill — does the two-step process still apply? The two-step process (goodwill first, then pro-rata) naturally collapses into a single step. You directly allocate the impairment loss pro-rata to all assets in the CGU, subject to the three floors. The logic and the iterative reallocation rule still apply fully.
Q3. How is the recoverable amount of a CGU determined when individual asset values are unavailable? You estimate FVLCD and VIU at the CGU level as a whole, using projected cash flows attributed to the unit. The higher of the two is the CGU's recoverable amount. Always cross-check the assumptions (discount rate, growth rate, terminal value) with what ICAI guidance prescribes — and verify in the latest ICAI study material / announcement for any updates.
