Inventory valuation rule that limits recorded inventory to the lower of cost or an applicable market measure.
Lower of cost or market, often shortened to LCM, is an inventory valuation rule that requires inventory to be reported at the lower of its recorded cost or a market-based replacement-oriented amount.
The purpose is conservative reporting. If inventory has declined in value, the business should not continue to carry it at an overstated amount.
LCM is one of the traditional ways to recognize inventory losses before the goods are sold. It protects the balance sheet from overstated asset values and reduces the risk that profit is inflated by inventory that no longer supports its recorded carrying amount.
Modern reporting discussions often focus on Net Realizable Value and the Lower of Cost and Net Realizable Value Rule. LCM remains important because many finance and accounting materials still use it as the standard comparison framework.
If inventory cost is $100,000 but the applicable market measure supports only $82,000, the carrying amount is reduced to $82,000. The $18,000 reduction affects current-period profit and prevents the balance sheet from carrying inventory above its recoverable measure.
Analysts use Lower of Cost or Market to connect accounting presentation with asset quality, earnings quality, liquidity, leverage, and period-to-period comparability. The practical issue is how recognition, measurement, classification, and disclosure change the ratios or judgments a reader relies on.
Ask whether Lower of Cost or Market changes recognized assets, liabilities, equity, income, cash flow, covenant ratios, or trend comparability.
Interpret Lower of Cost or Market as decision evidence, not just a definition. Its weight depends on the transaction, measurement date, jurisdiction, market conditions, and whether Lower of Cost or Market changes cash flow, risk allocation, reported performance, controls, or investor behavior.
In practice, Lower of Cost or Market matters most when it changes a pricing input, contractual right, reporting classification, liquidity choice, tax outcome, or risk-control decision. If none of those change, Lower of Cost or Market is descriptive rather than decision-critical.
Do not confuse Lower of Cost or Market with the underlying economic event. The accounting treatment explains recognition or measurement; analysis still asks whether cash flow, risk, leverage, and comparability changed.

Treat Lower of Cost or Market as decision-useful only when it changes a forecast, contractual right, accounting result, tax outcome, market price, liquidity need, or risk-control action. If those items do not change, Lower of Cost or Market is descriptive rather than analytical evidence.
Check the statement line, footnote definition, accounting policy, period, recurrence, comparability adjustment, and model link before using Lower of Cost or Market in valuation or credit work. The evidence should explain whether the measure changes earnings quality, cash conversion, leverage, or enterprise value.

The useful question for Lower of Cost or Market is not only what the label means, but whether it changes a number someone will rely on.
In practice, check Lower of Cost or Market against the accounting policy or source record, the affected line item or ratio, and the cash-flow or disclosure consequence.
