What is Inventory Write-Down?

Inventory Write-Down is a process in inventory accounting that is utilized to reduce the inventory value on the balance sheet when the inventory's market value diminishes below the book value.

Inventory write-downs are accounting principles that reduce the value assigned to a given inventory's market value on the balance sheet.

Inventories are susceptible to depreciation when assets lose value over time until their value tends to zero. Depreciation is controlled by factors such as market conditions (climate), damage, obsolescence, or even theft.

As a result, the market value of given inventory items can sometimes be lower than the asset's book value. Book value is defined as the net value of the asset in the balance sheet or the original price used to purchase the asset.

Market value is defined as the amount in which the given asset can be sold in the open market, or specifically, the spot price of the given asset (inventory) given current market conditions (demand and supply). This realizable value might sometimes be above or below the book.

Such write-downs affect the company's balance sheet and income statement, as well as its business net income and related earnings.

Write-downs should also be done as soon as possible so that financial statements would immediately reflect the current state of the company’s inventory and, by extension, the reduced value of the inventory.

Suppose the inventory asset value and the cumulative value of the inventory reflected in the balance sheet are seen as too high. In that case, this is misleading to the readers of the companies’ financial statements, which might implicate the company in lawsuits or legal challenges.

Key Takeaways

  • An inventory write-down is an accounting process where the book value of inventory is reduced to reflect its current market value or net realizable value when that value is less than the cost at which it is currently recorded.
  • Lower of Cost or Market (LCM) is where inventory should be recorded at the lower of its historical cost or current market value.
  • Net Realizable Value (NRV) is where the inventory may be written down to its net realizable value, which is the estimated selling price minus any costs to complete and sell the inventory.
  • The typical journal entry for an inventory write-down involves debiting a loss or expense account and crediting inventory.

Accounting For Inventory Write-Downs

When an item is identified for inventory write-down, the write-down occurs immediately; the entire amount is charged to the expense at once.

This write-down will not be spread over multiple future periods, as this would indicate some benefit accruing to the business over the write-down period, which is not the case in these instances.

For instance, with an original value of $1,000 in computers, a software company that had its hardware stolen of a total value of $400 would reflect an inventory write-down in its accounts. 

Since this inventory write-down is significant in size, the expense is recorded in a separate account so that aggregate size can be tracked. The write-downs are debited, and the inventory is credited.

Example of Amount of Debit and Credit
  Debit Credit
Inventory write-down expense 400 -
Inventory - 400

The opposite case, where the inventory write-down is not significant in size, is seen. In this, the general cost of goods sold is debited, and inventory is credited.

Example of Debit and Credit Amount
  Debit Credit
Cost of goods sold 400 -
Inventory - 400

As seen in the examples above, both inventory accounts are credited regardless of whether the inventory write-down is significant in size.

Further, the determination of whether the inventory write-down is significant in terms of size is fully based on the company. The company could impose specific matrices or assessment criteria that determine the severity of the write-down and is not fixed company to company.

Reversal of Inventory Write-Down

In rare specific cases, inventory write-downs can be reversed. This could come in cases that involve the estimated initial write-down being lower than the net realizable value of inventory.

For instance, this specific case could happen if market conditions change drastically. Basically, any change that fundamentally alters the inventory’s spot market value to the green.

Since assessments are conducted every reporting period, the assessment coordinator would determine if there is clear evidence of value differences.

 If there are, this individual would properly and promptly report it to superiors, who would initiate this reverse in inventory write-downs.

However, Generally Accepted Accounting Principles (GAAP) do not allow for reversals in inventory write-downs; hence, the lower inventory value will be kept and reflected.

However, the International Financial Reporting Standards (IFRS) allow for reversals in inventory value due to causes of depreciation but not because of goodwill.

Why Do Write Downs Happen?

In terms of what assets/items/inventory accounts should be considered for a write-down, the list is extensive. Raw materials, in-progress products (secondary goods), and even finished merchandise can all be considered for inventory write-down and are subject to depreciation.

If the inventory loses all its value, the item is written off as an “inventory write-off” instead of an " inventory write-down.”

Such “write-downs” are treated as expense items. As a result, this impacts both net income and tax liability, reducing them. Inventory write-downs also affect both the balance sheet and the income statement, resultantly. 

When net income is reduced, the business’ retained earnings fall as well. While this affects the income statement, the fall in net income will cause shareholders’ retained earnings to minimize, affecting the balance sheet as well.

Along with this, the inventory asset value in the balance sheet is also further reduced along with its accurate net realizable value (NRV).

Note

Net realizable value (NRV) is defined as the difference between the asset's expected sale price and the total sale or disposal cost. NRV is commonly used to determine a specific asset's lower cost or market rule.

The lower cost or market rule means that businesses must ensure that the cost of inventory is reflected at whichever value is lower—the market or the original cost of the asset.  

For instance, if NRV is positive, that means that the expected sale price is higher, and therefore, the original cost of the asset reflected in the sheets will be changed out to input the spot market price/cost of the asset.

Likewise, if NRV is negative, the market cost is higher. Therefore, the asset's original cost reflected in the sheets will be retained.

Impact of Inventory Write-Downs on Financial Ratios 

Recorded inventory write-downs can affect various financial ratios. Some common multiples will be affected, as well as specific margins.

1. Current ratio

This decreases due to inventory write-downs. Current ratios are defined as the ratio between current assets and current liabilities. Inventory write-downs, which are reflected as expenses, lower the company’s net income.

If the company’s net income falls, its total current assets will also fall as cash or retained earnings fall. Since the amount of current assets falls, the current ratio will reduce.

2. Inventory turnover

It is defined as the rate at which inventory is used, sold, or replaced. It is calculated by dividing the cost of goods sold by the average inventory at the selling price. 

Inventory write-downs result in a reduction in the value of inventory on the balance sheet to reflect its lower worth, reducing net income and thus reducing the cost of goods sold.

Note

When COGS are reduced, the inventory turnover ratio will increase.

3. Days of inventory on hand

Days of inventory on hand, or inventory days, are calculated through

(Average Inventory/ Cost of Goods Sold) * 365/ 366

Days of inventory on hand are defined as the number of days that a business takes to sell and finish its inventory stock. 

Since net income falls, the cost of goods sold will fall, which will result in an increase in days of inventory on hand.

4. Net profit margin

Calculated as:

(Revenue - Cost)/ Revenue

Net profit margin is defined as the amount of profits generated per $1 in sales.

Specifically, it is calculated by deducting all company expenses (all costs, including COGS, tax liabilities, and administrative costs) from total revenue. 

Note

Revenue minus cost is also the net margin; hence, the answer is in percentage form when divided by revenue.

When net income falls, the numerator in the equation, which is revenue-cost, falls. This results in the net profit margin falling.

5. Gross profit margin

Calculated as:

(Revenue - COGS) / Revenue. 

This matrix is similar to the net profit margin, but instead of cost being deducted from revenue, COGS is used instead.

Unlike net profit margin, gross profit margin calculates the profit taken by the company after accounting for the direct costs involved in doing its business of creating the product. 

As the value of inventory on the balance sheet falls, reflecting lower values, net income is reduced, and as a result, the cost of goods sold reduces as well. As COGS falls, the equation's numerator increases, resulting in an increasing gross profit margin.

Summary

Inventory write-downs play a crucial role in accurately reflecting the value of inventory on a company's financial statements. They address the depreciation and obsolescence of inventory, ensuring that the reported figures align with the economic reality.

By reducing the value of inventory to its market value, write-downs help prevent misleading financial statements that could have serious implications for stakeholders. 

They directly affect the income statement by reducing net income, which in turn influences profitability ratios such as net profit margin and gross profit margin. 

These ratios provide valuable insights into a company's ability to generate profits relative to its revenue and cost of goods sold. Furthermore, write-downs affect liquidity ratios, such as the current ratio, which measures a company's ability to meet short-term obligations.

Companies must promptly recognize inventory write-downs to ensure transparency and accuracy in financial reporting. 

By doing so, they provide a clear picture of the company's financial health and mitigate the risk of potential lawsuits or legal challenges resulting from misleading information.

Note

Inventory write-downs demonstrate prudent financial management. They reflect a company's commitment to presenting reliable and realistic financial statements, enhancing investor confidence, and facilitating informed decision-making.

These ratios provide insights into a company's liquidity, efficiency in managing inventory, and overall profitability. They are very important to assess and continually update as the business undergoes changes, transitions, or market changes.

Properly recording inventory write-downs is crucial for transparent financial reporting and ensuring the financial statements accurately represent the company's financial position.

Management needs to evaluate and determine the appropriate value for write-downs, considering factors such as market conditions and the physical condition of the inventory.

Overall, inventory write-downs are essential to inventory management and financial accounting, helping companies maintain accurate financial records and make informed business decisions.
