Inventory is the most physically tangible asset on the balance sheet and, paradoxically, one of the most judgment-dependent. The steel sits in the warehouse. The components sit on the shelf. The finished goods sit in the dispatch area. The physical reality is observable. The financial measurement of that reality is not.
Under Ind AS 2, inventory is carried at the lower of cost and net realisable value (NRV). The principle is straightforward. Its application requires judgments that can preserve reported margins long after the underlying economics have deteriorated.
Cost itself is a judgment: which cost formula (FIFO, weighted average)? What is included in cost (direct materials, direct labour, production overheads at normal capacity)? How are overheads allocated across products? Each choice affects the unit cost, and therefore the margin, reported for every product.
NRV is a judgment: what price can the inventory actually be sold for, less estimated costs of completion and selling? For active, fast-moving inventory in a stable market, NRV is straightforward. For slow-moving inventory in a declining market, for work-in-progress in a project that may not complete, for raw materials whose end-product is losing demand, NRV is an estimate that depends on management’s view of a future that may not materialise.
The trap: inventory can preserve reported profit until the economics eventually force the loss into the accounts. A company that delays recognising that its inventory is worth less than its carrying cost reports higher margins today and absorbs a larger write-down tomorrow.
Where the Trap Opens
Slow-moving inventory carried at cost
A company with Rs 50 crore of finished goods that has been in the warehouse for more than 12 months without a sale is carrying inventory at a cost that the market may no longer support. The product may be superseded by a newer version, out of fashion, approaching expiry or simply unwanted by the customer base that originally justified the production run.
Ind AS 2 requires a write-down to NRV when cost exceeds NRV. The write-down depends on management’s estimate of what the inventory can be sold for. If management estimates that the slow-moving inventory can be sold at a discount of 15%, the write-down is Rs 7.5 crore. If the inventory is ultimately sold at a 40% discount (or scrapped entirely), the actual loss is Rs 20 crore or more. The Rs 12.5 crore gap between the provision and the actual loss is margin that was reported in prior periods but was not economically real.
The forensic signal: inventory ageing. A growing proportion of inventory in the 6-to-12-month and over-12-month categories, without a proportional increase in write-down provisions, indicates that the balance sheet is carrying stale inventory at values the market will not support.
Overhead absorption at “normal” capacity
Ind AS 2 requires production overheads to be allocated to inventory based on “normal capacity,” which is the production the facility is expected to achieve on average over several periods under normal circumstances. When actual production falls below normal capacity, the unallocated overhead is expensed as a period cost, not included in inventory.
The judgment: what is “normal” capacity? A company operating at 60% utilisation that defines normal capacity as 65% allocates nearly all its overhead to inventory, keeping reported margins intact. A company that defines normal at 85% must expense 25% of its overhead as unallocated, reducing reported margins.
The temptation: define normal capacity at a level close to actual capacity, so that most overhead is absorbed into inventory and the P&L is protected. The consequence: inventory is valued at a cost that includes overhead that would not have been allocated if capacity utilisation were honestly assessed.
Cost formula selection
The choice between FIFO and weighted average affects reported margins when input costs are changing. In a period of rising raw material costs, FIFO produces lower COGS (older, cheaper inventory is consumed first) and higher margins. Weighted average produces COGS that reflects the blended cost across periods, typically resulting in lower margins than FIFO during price increases.
The choice is not wrong. Both methods are compliant with Ind AS 2. But the choice affects reported margins, and a change in method (from weighted average to FIFO during a period of rising costs) produces a margin improvement that is entirely accounting-driven.
NRV estimation for work-in-progress
Work-in-progress (WIP) presents a particular challenge because the NRV depends on the estimated selling price of the finished product less the estimated costs to complete. Both estimates are management judgments.
A construction company with Rs 40 crore of WIP related to a project whose customer is in financial difficulty carries the WIP at cost. The NRV depends on whether the customer will pay for the completed project. If the customer defaults, the NRV may be zero. The Rs 40 crore of WIP becomes a Rs 40 crore loss. The loss existed economically at the point when the customer’s financial difficulty became apparent. The accounting recognised it only when the default crystallised.
Write-down reversals
Ind AS 2 permits the reversal of a previous write-down when the circumstances that caused the write-down no longer exist. A reversal increases the inventory carrying value and reduces COGS, improving reported margins.
The reversal is legitimate when circumstances genuinely change: a product that was slow-moving finds a new market, a raw material that was thought obsolete becomes useful for a different product. The reversal is suspicious when it occurs in a period of weak operating performance, suggesting that the write-down was excessive (creating a cookie-jar reserve) and the reversal is used to inflate margins when operational performance cannot.
The Forensic Methodology
In Northrop Management Private Limited’s forensic and due diligence practice, inventory valuation analysis follows a structured examination.
Step 1: Age the inventory. Classify the entire inventory by age: less than 30 days, 30 to 90, 90 to 180, 180 to 365, over 365. Calculate the write-down provision for each age category and compare to management’s actual provision. If management’s provision is materially below the provision implied by the ageing (based on industry benchmarks for NRV by age category), the inventory is potentially overvalued.
Step 2: Test NRV against recent sales. For each significant inventory category, compare the carrying cost to the actual selling price achieved in the most recent three months. If the selling price is below cost, the inventory should be written down to the selling price less costs to sell. If recent sales do not exist (because the product is not selling), the NRV may be significantly below cost.
Step 3: Examine capacity utilisation and overhead allocation. Determine the “normal capacity” assumption used for overhead allocation. Compare to actual capacity utilisation over the last 12 months. If actual utilisation is materially below normal, assess whether the unallocated overhead has been properly expensed.
Step 4: Test write-down and reversal patterns. Plot inventory write-downs and reversals over five years. Compare to operating performance. If write-downs are concentrated in strong years (building reserves) and reversals in weak years (releasing reserves), the pattern is consistent with earnings management.
Step 5: Physical verification. For the highest-value inventory categories, verify physical existence, condition and location. Compare physical counts to book quantities. Investigate discrepancies. Assess whether the physical condition of the inventory supports the carrying value.
Ashish Chaudhary, frames the forensic principle directly: “Inventory can preserve reported profit until the economics eventually force the loss into the accounts. A company that delays writing down slow-moving inventory, that defines normal capacity to absorb overhead into stock, that selects the cost formula that flatters margins and that reverses write-downs when earnings need support is not violating accounting standards. It is using the judgment the standards provide to delay the recognition of economic reality. The forensic question is not whether the judgment is permissible. It is whether the judgment reflects the inventory’s actual value.”
Questions for the Boardroom
- What percentage of our inventory is more than 180 days old, and what write-down provision exists against that category?
- How does our carrying cost compare to the actual selling prices achieved in the most recent quarter for each major product category?
- What “normal capacity” assumption do we use for overhead allocation, and how does it compare to actual utilisation over the last 12 months?
- Have we reversed any inventory write-downs in the last three years, and did those reversals correlate with periods of weak operating performance?
- If we marked every inventory item to its current NRV, what would the total write-down be, and how does it compare to our existing provision?
Closing Implication
Inventory valuation is where physical reality meets accounting judgment. The inventory is in the warehouse. Its value, as reported on the balance sheet, depends on cost formulas, overhead allocation, capacity assumptions and NRV estimates that management controls. A company whose inventory valuation judgments consistently favour higher carrying values is a company whose reported margins include a component that the market may not support. The gap between carrying value and realisable value is the inventory valuation trap, and it closes, always, when the economics can no longer be deferred.
