Inventory valuation
The previous sections of the inventory chapter discuss the costs included in inventory.
In summary, the inventory account should initially be valued at cost. If there are no special circumstances affecting the value of the inventory that the company is holding, the inventory will continue to be valued at cost and when they are sold, this cost value will go to the cost of goods sold.
However, at certain instances, inventories can be damaged or obsolete. In this case, the company is not anymore able to sell the inventory in the intended original state resulting in expected revenues from selling the inventories to be lower than its cost. When this happens, it is important to recognize this loss as it happens by reducing the value of inventories in 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 or net realizable value (LCNRV) |
|
The lower of between the:
|
| Method 2:
Lower of cost or market (LCM) |
|
The lower between the:
|
** 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. This is not covered by the CMA exams so it is not discussed in detail.
When the NRV (from Method 1) or market value (from Method 2) is lower than the recorded cost of the inventory, the inventory should be written down to avoid overstating the assets of the company. The journal entry to record the write-down the inventory is as follows:
| Account | Debit | Credit | Financial statement element |
| Loss on inventory write-down | XXX | Loss | |
| Inventory | XXX | Asset | |
| To record inventory write-down | |||
It is also acceptable to debit the write-down to cost of goods sold (COGS). It depends on the policy of the company.
When comparing US GAAP versus IFRS, the following should be noted:
- The “lower of cost or market value method” is only used in US GAAP and not under IFRS. This makes sense because LIFO is not allowed under IFRS. Only lower of cost or NRV is being used for inventory valuation under IFRS
- Impairments of inventory in the previous periods can be recovered (i.e., reversed) under IFRS. However, this is prohibited in US GAAP.
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. For this method, the following inputs are needed:
- Cost
- NRV
- Replacement cost
- NRV less normal profit margin
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.
| LCM inputs | Designated market value | |||||||||
| Product | Cost
(in $) |
Selling price
(in $) |
Selling cost
(in $) |
Profit margin
(in $) |
NRV
(SP - SC) (in $) |
Replacement cost | NRV less profit margin | Designated MV (Median) | Designated MV
(in $) |
LCM |
| Item 1 | 180 | 200 | 30 | 30 | 170 | 160 | 140 | Replacement cost | 160 | 160 |
| Item 2 | 250 | 300 | 20 | 30 | 280 | 270 | 250 | Replacement cost | 270 | 250 |
| Item 3 | 400 | 500 | 70 | 100 | 430 | 380 | 330 | Replacement cost | 380 | 380 |
| Item 4 | 320 | 350 | 50 | 35 | 300 | 315 | 265 | NRV | 300 | 300 |
| Item 5 | 210 | 250 | 20 | 25 | 230 | 190 | 205 | NRV less profit margin | 205 | 205 |
| 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.
