Inventory valuation
Inventory is first recorded at cost, and that cost moves to cost of goods sold when the goods are sold. If inventory becomes damaged or obsolete, the company may expect to collect less than its cost. U.S. GAAP then requires the loss to be recognized right away by writing the inventory down on the balance sheet.
This process is called inventory valuation, which is part of the subsequent measurement of inventories under US GAAP.
The rules for inventory valuation depend on which cost flow assumption is used by the company:
| Method | Applicable for cost flow assumptions | Valuation method |
| Method 1:
Lower of cost and net realizable value (LCNRV) |
|
The lower of:
|
| Method 2:
Lower of cost or market (LCM) |
|
The lower of:
|
** The retail inventory method is a method of costing inventories used by department stores that tracks inventory costs using the retail value and applying the cost/retail ratio. The mechanics of the retail method are beyond this chapter; just remember that inventory costed with it is valued at lower of cost or market.
When the NRV (Method 1) or market value (Method 2) is below recorded cost, the inventory is written down by debiting a loss on inventory write-down (or cost of goods sold, depending on company policy) and crediting inventory.
When comparing US GAAP to IFRS for inventory valuation:
Sample situation
An example situation is provided below. We need to determine the inventory value using the two different methods discussed.
The ending inventory of Achievable Co. is composed of the following:
| Product | Selling price
(in $) |
Profit margin
(in %) |
Profit margin
(in $) |
Cost
(in $) |
Replacement cost
(in $) |
Selling cost
(in $) |
| Item 1 | 200 | 15% | 30 | 180 | 160 | 30 |
| Item 2 | 300 | 10% | 30 | 250 | 270 | 20 |
| Item 3 | 500 | 20% | 100 | 400 | 380 | 70 |
| Item 4 | 350 | 10% | 35 | 320 | 315 | 50 |
| Item 5 | 250 | 10% | 25 | 210 | 190 | 20 |
Method 1: Lower of cost and net realizable value (LCNRV)
If the company is using cost flow assumptions other than LIFO or the retail method, the LCNRV method should be used.
Under the LCNRV, the only relevant inputs are the following:
- Cost
- Selling price
- Costs to complete
- Costs to sell
In this example, there are no costs to complete the inventory. All other inputs should be ignored.
The analysis can be done on the inventory as a whole or per inventory item. When done per inventory item, this will result in the lowest amount of inventory since there is no possible offsetting of impacts. We will present the solution by analyzing the valuation per inventory item which is the recommended way to do it when the problem is silent in the CMA exam.
| Product | Selling price
(in $) |
Selling cost
(in $) |
NRV
(SP - SC) |
Cost
(in $) |
Lower amount | Cost to record |
| 1 | 200 | 30 | 170 | 180 | NRV | 170 |
| 2 | 300 | 20 | 280 | 250 | Cost | 250 |
| 3 | 500 | 70 | 430 | 400 | Cost | 400 |
| 4 | 350 | 50 | 300 | 320 | NRV | 300 |
| 5 | 250 | 20 | 230 | 210 | Cost | 210 |
| 1,410 | 1,360 | 1,330 |
The total inventory should be valued at $1,330 based on the LCNRV method applied per inventory item. Since the total cost is at $1,360, inventory should be written down by $30. The write-down is recorded as follows:
| Account | Debit | Credit | Financial statement element |
| Loss on inventory write-down | $30 | Loss | |
| Inventory | $30 | Asset | |
| To record inventory write-down | |||
You should notice that if we apply the LCNRV to the total of the inventory items, there should be no inventory write-down because of the offsetting impacts.
Method 2: Lower of cost or market (LCM)
If the company is using LIFO or the retail method, the LCM method should be used.
As with LCNRV, the LCM analysis can be done per inventory item or on the inventory as a whole; we’ll again analyze it per item, since that’s the recommended approach when the problem is silent.
Steps in the LCM method
Step 1:
Calculate the designated market value as the middle value of the three amounts:
- NRV (the “ceiling”)
- Replacement cost
- NRV less normal profit margin (the “floor”)
The amount selected must be the exact amount in between and not the average of the three. See example solution below.
Step 2:
Compare the designated market value to the cost. Any amounts lower than cost require a write-down.
| Product | Cost (in $) | NRV | Replacement cost | NRV less profit margin | Designated market value | LCM |
|---|---|---|---|---|---|---|
| Item 1 | 180 | 170 | 160 | 140 | 160 (replacement cost) | 160 |
| Item 2 | 250 | 280 | 270 | 250 | 270 (replacement cost) | 250 |
| Item 3 | 400 | 430 | 380 | 330 | 380 (replacement cost) | 380 |
| Item 4 | 320 | 300 | 315 | 265 | 300 (NRV) | 300 |
| Item 5 | 210 | 230 | 190 | 205 | 205 (NRV less profit margin) | 205 |
| Total | 1,360 | 1,315 | 1,295 |
Based on the above (see last column), the inventory should be valued at $1,295, while the cost recorded (see second column) in the books is $1,360. This means that the inventory should be written down by $65. The following journal entry is required to record the write-down:
| Account | Debit | Credit | Financial statement element |
| Loss on inventory write-down | $65 | Loss | |
| Inventory | $65 | Asset | |
| To record inventory write-down | |||
You should notice that if we apply the LCM to the total of the inventory items, the offsetting impacts shrink the write-down but do not eliminate it: the total cost of $1,360 still exceeds the total designated market value of $1,315, giving a $45 write-down rather than the $65 computed item by item.
