Inventory Write-Downs and Obsolescence: A Practical Playbook for Finance and Operations
Every storeroom hides a problem nobody wants to name. Somewhere on the shelves sits stock that will never sell at the price it was bought for, or will never sell at all. Through 2021 and into 2022, fear of shortages pushed many organizations to over-order and double-source, and now some of that safety stock has aged into a liability. An inventory write-down is the accounting recognition that goods are worth less than their recorded cost, and handling it well is both a finance discipline and an operational one.
Spotting the stock at risk
Obsolescence rarely announces itself. It accumulates in the corners while the team focuses on what is moving. The first job is to make slow and dead stock visible with a few honest measures rather than gut feel.
Days of inventory on hand by item, so a part with two years of cover stands out from one with two weeks.
Last issue or sale date, which separates slow movers from genuinely dead stock that has not moved in many months.
Excess over forecast: quantity on hand beyond what demand over a sensible horizon can absorb.
Shelf-life and revision status, so expiring lots and superseded part numbers are flagged before they become worthless.
Measuring and recording it correctly
Accounting standards require inventory to be carried at the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less the costs to complete and sell. When that figure drops below cost, the difference is written down as an expense in the period you identify it, not deferred to whenever the item is finally scrapped. A few principles keep the number defensible.
Estimate net realizable value honestly. Base it on real evidence: actual discounted sale prices, scrap or salvage value, or a reasonable provision percentage by age band. Avoid wishful pricing that assumes a market that no longer exists.
Write down, do not write off prematurely. A write-down reduces carrying value to its recoverable amount while the goods may still sell at a discount. A write-off removes them entirely, and is appropriate only when there is no recoverable value.
Reverse if conditions genuinely improve. Under IFRS, if net realizable value recovers, a previous write-down can be reversed up to the original cost. This is not permitted under US GAAP, so know which framework you report under.
Document the judgement. Record the method, the ageing bands, and the assumptions. A write-down that auditors and leaders can trace is far easier to defend than a round number that appears from nowhere.
Preventing the next pile
A write-down cleans up the past; it does not stop the future. The volatility of recent years tempted many teams to hold more of everything, and the discipline now is to right-size that buffer rather than abandon it. Prevention is mostly about better signals and tighter habits, not heroic forecasting.
Review slow and dead stock on a fixed cadence so problems surface monthly instead of at year-end.
Set and enforce maximum stock levels and reorder points that reflect current, not pandemic-peak, demand.
Tighten engineering and product change control so superseded parts are run down or returned before the new revision lands.
Build supplier terms that allow returns, buy-backs, or smaller, more frequent lots to reduce the cost of being wrong.
Treated this way, the annual scramble to clear obsolete stock becomes a routine, low-drama review. The balance sheet tells the truth, cash stops sitting idle on shelves, and the warehouse holds what the business actually needs rather than what it feared it might.
