Recording Inventory Losses under the LCM Rule - dummies

Recording Inventory Losses under the LCM Rule

Businesses should apply the lower of cost or market (LCM) rule to inventory, regardless of which method they use to record cost of goods sold and inventory cost. Acquiring and holding an inventory of products involves certain unavoidable economic risks.

These risks include:

  • Deterioration, damage, and theft risk: Some products are perishable or otherwise deteriorate over time, which may be accelerated under certain conditions that are not under the control of the business (such as the air conditioning going on the blink).

    Most products are subject to damage when they’re handled, stored, and moved (for example when the forklift operator misses the slots in the pallet and punctures the container). Products may also be stolen (by employees and outsiders).

  • Replacement cost risk: After you purchase or manufacture a product, its replacement cost may drop permanently below the amount you paid (which usually also affects the amount you can charge customers for the products).

  • Sales demand risk: Demand for a product may drop off permanently, forcing you to sell the products below cost just to get rid of them.

A business should regularly inspect its inventory very carefully to determine loss due to theft, damage, and deterioration. And the business should go through the LCM routine at least once a year, usually near or at year-end.

The process of applying LCM consists of comparing the cost of every product in inventory — meaning the cost that’s recorded for each product in the inventory asset account according to the FIFO or LIFO method (or whichever method the company uses) — with two benchmark values:

  • The product’s current replacement cost (how much the business would pay to obtain the same product right now)

  • The product’s net realizable value (how much the business can sell the product for)

If a product’s cost on the books is higher than either of these two benchmark values, an accounting entry is made to decrease product cost to the lower of the two. In other words, inventory losses are recognized now rather than later, when the products are sold.

The drop in the replacement cost or sales value of the product should be recorded now, on the theory that it’s better to take your medicine now than to put it off. Also, the inventory cost value on the balance sheet is more conservative because inventory is reported at a lower cost value.

Some shady characters abuse LCM to cheat on their income tax returns. They knock down their ending inventory cost value — decrease ending inventory cost more than can be justified by the LCM test — to increase the deductible expenses on their income tax returns and thus decrease taxable income.

A product may have proper cost value of $100, for example, but a shady character may invent some reason to lower it to $75 and thus record a $25 inventory write-down expense in this period for each unit — which is not justified.

Even though the person can deduct more this year, he will have a lower inventory cost to deduct in the future. Also, if the person is selected for an IRS audit and the Feds discover an unjustified inventory knockdown, the person may end up with a felony conviction for income tax evasion.
