Inventory Write-Downs and Lower of Cost or NRV

A retailer buys winter coats for $50 each. If fashions shift and those coats can now only be sold for $30, accounting rules do not let the company keep pretending they are worth $50 on the balance sheet. Inventory must be carried at the lower of cost or net realizable value (NRV) — cost being what was paid, NRV being the expected selling price minus remaining costs to sell.

The write-down hits the income statement as an addition to cost of goods sold (or a separate loss line), shrinking gross margin in the period the damage is recognized — even though no sale happened. This matters for analysts because a sudden write-down often signals that demand assumptions embedded in an inventory build were too optimistic, and it can flatter future margins once the bad inventory is already off the books at its lower value.

Worked example. A company holds 10,000 units at a cost of $50 each ($500,000 total). Retail conditions sour, and management now expects to sell each unit for $38, with $3 per unit in remaining selling costs, giving an NRV of $35. Since $35 is below the $50 cost, the inventory is written down to $35 x 10,000 = $350,000, and $150,000 is expensed immediately as a loss.

Once written down, the new $35 basis becomes the "cost" going forward — under most standards it cannot later be written back up if conditions improve, so investors should treat a large write-down as a real, largely irreversible acknowledgment that a prior purchase or production decision did not pan out.
