Inventory Obsolescence Risk Review

Inventory obsolescence risk review examines stock that may no longer be sold or used at its recorded value because of age, expiry, damage, replacement or weak demand. It combines physical verification, demand evidence and valuation policy. Old inventory is a signal for investigation, not automatic proof of zero value.

From the Money Master HQ dictionary, founded by Shihan Sheriff (FCMA, VP of Finance at Nomod, CFO at Esanjo Ventures). How these definitions are written.

What it means

A retailer has thousands of units that appear as assets, but their model is being replaced, so selling at full price is unlikely. Inventory obsolescence risk review asks what is physically held, what demand remains and whether the recorded value is supportable.

IFRS IAS 2 requires inventories to be measured at the lower of cost and net realizable value under that standard, and Oracle NetSuite describes practical signs of obsolete stock, including items that no longer sell or have become outdated. Accounting requirements vary by reporting framework, and an ageing report is a risk screen, not an automatic write-down formula.

Define the population to include finished goods, components and work in process as appropriate, excluding goods owned by others or recording them separately. Check physical stock by reconciling system quantity with counts, transfers and returns, because a risk review built on phantom quantities will overstate exposure.

Segment age by comparing receipt or production dates with expected sale or use, since one age cutoff cannot describe a seasonal product and a long-life spare part equally. Review movement, because low sales over a recent period may signal risk but planned projects can justify holding stock, so verify future demand evidence, and check seasonality with comparable seasons and storage-life evidence, since a product with no recent sales may still be needed next season.

Watch product changes such as new models, specifications and packaging that can make old versions hard to sell, and confirm whether customers still accept them. Check expiry, since food, medicine, chemicals and warranties can have strict dates and applicable safety and regulatory rules must be followed before any sale, and review condition, because damage, improper storage and quality holds can reduce realizable value even if the item is new.

Look at customer returns, as repeated returns or complaints can show an item is less saleable than its ledger balance implies, so separate unopened from unusable goods. Check market price, because a competitor's cheaper replacement or falling commodity price can affect expected selling value, and use evidence for comparable specifications.

Estimate selling costs, since net realizable value under IAS 2 considers estimated selling price less costs to complete and make the sale, so a headline price is not the final amount. Analyse components, because a spare part may be useful only for a product that is no longer supported, and check reservations, since stock earmarked for a firm customer order may be less risky than unallocated stock if the order is valid and its cancellation terms are confirmed.

Calculate a risk amount as quantity times carrying cost, which is an exposure ceiling for a simple screen, not the expected loss, and assess recoverable value item by item where material. Track age bands by value and report both count and currency amount, since a large number of cheap units may matter less than a smaller high-value obsolete part.

Separate accounting from action, because a write-down reflects expected recoverability but does not remove physical stock or solve storage congestion, and a financial allowance can change without a physical movement while a physical disposal needs its own approval and record. Review forecasts, since demand-planning error, promotional failure or late engineering changes may cause the build-up, assign ownership (finance owns valuation policy, operations confirms condition, product teams assess replacement and sales tests demand), document assumptions and the review date, and check future cash because unsold goods tie up space and cash and disposal may cost money; for an owner, the review asks whether inventory is useful and worth its recorded amount, not whether old stock is automatically worthless.

In practice

Real-world examples.

1

Example

A discontinued model remains in stock after the replacement arrives.

2

Example

Seasonal goods have not sold for months but still have a supported next-season market.

3

Example

A component is new but unusable because the product it serves has been withdrawn.

Formula

Calculation

Gross exposure = Units at risk x Carrying cost per unit Worked example. A discontinued model leaves 200 units in stock, each carried at $40. - Gross exposure = 200 x $40 = $8,000, which is not an $8,000 loss. - Suppose operations and sales support a recoverable value of $15 per unit, or 200 x $15 = $3,000 in total. The indicated write-down is then $8,000 - $3,000 = $5,000. Any write-down depends on supported realizable value and the applicable accounting framework, so the $5,000 is an illustration of the method, not a rule.

Case study

Seen in the real world.

This entirely fictional example follows Valley Devices. A new product version left 200 old units in storage. Sales confirmed limited discount demand, operations checked whether parts could be reused and finance assessed valuation under its policy. The case does not assume a particular mandatory write-down for all reporting frameworks.

Watch out

Common mistakes.

  • Writing down every item older than a fixed number of days without checking demand.
  • Using the list price instead of expected net realization under an applicable valuation rule.
  • Booking a reserve while leaving the stocking and purchasing cause unaddressed.

Questions

People also ask.

Is slow-moving stock always obsolete?

No. Check supported demand, condition, shelf life and practical use.

What does the review measure?

Quantity, carrying amount, expected recovery and reasons for risk.

Who decides the accounting adjustment?

Finance applies the relevant reporting standard with evidence from operations and sales.
