Lower of Cost or Net Realizable Value / Lower of Cost or Market

11.3 Lower of Cost or Net Realizable Value / Lower of Cost or Market

A key aspect of inventory accounting for both U.S. Generally Accepted Accounting Principles (GAAP) and International Financial Reporting Standards (IFRS) relates to determining the appropriate valuation when inventory value declines below its historical cost. This topic centers on the concept of always carrying inventory on the balance sheet at the “lower of cost or net realizable value” (LCNRV) under certain methods—or, in other situations under U.S. GAAP, the “lower of cost or market” (LCM).

While both LCNRV and LCM approaches aim to ensure that an entity’s balance sheet does not overstate inventory value, there are important technical details and differences in application under GAAP vs. IFRS. Additionally, there are notable exceptions for particular inventory cost-flow methods (LIFO and the retail inventory method) under GAAP that do not apply under IFRS. This section will examine:

• The fundamental concepts of LCNRV and LCM
• Differences between U.S. GAAP and IFRS
• Specific rules for LIFO and retail inventory method under GAAP
• Detailed examples, including step-by-step illustrations

Overview of LCNRV and Market Concepts

Under both U.S. GAAP and IFRS, a company initially records inventory at its “cost,” which typically includes all charges necessary to bring inventory to its current location and condition. However, if the inventory’s value is impaired because of changes in market conditions, obsolescence, or other factors, the entity may need to write down (reduce) the carrying amount of inventory.

1. Under U.S. GAAP (for FIFO, average cost, or specific identification methods), the inventory is measured at the lower of its cost or net realizable value.
2. Under U.S. GAAP (for LIFO or the retail inventory method), different guidance applies. The measure is the lower of cost or market (LCM), where “market” is an interim measure subject to a defined “ceiling” and “floor.”
3. Under IFRS, the rule is universally the lower of cost or net realizable value (LCNRV). IFRS forbids the use of LIFO, which removes the LCM complexities for IFRS reporters.

“Net realizable value” (NRV) is generally defined as the estimated selling price in the ordinary course of business, minus the reasonably predictable costs of completion and disposal.

“Market” (in GAAP’s LCM context for LIFO/retail) arguably means “replacement cost,” bounded by a “ceiling” (NRV) and a “floor” (NRV minus a normal profit margin). This is distinct from IFRS, where only NRV is used as the threshold.

Lower of Cost or Net Realizable Value (LCNRV)

Definition and Scope

LCNRV is a principle that requires companies to compare the inventory’s historical cost with its NRV—and, if the NRV is lower, the inventory is written down to this lower value.

Under U.S. GAAP, LCNRV applies to all inventory measured by:

• FIFO (First-In, First-Out)
• Weighted-average cost
• Specific identification
• Other methods (except LIFO or retail)

Under IFRS, LCNRV applies to all inventory (IFRS does not permit LIFO). Therefore, IFRS uses LCNRV universally.

Net Realizable Value (NRV)

• NRV = Estimated Selling Price – Estimated Costs to Complete and Sell
• This measure ensures the reported value is not higher than what management realistically expects to recover through sale.

Write-Down and Reversal

• Under U.S. GAAP, once a company has written down its inventory to NRV, this new cost is considered the “cost basis” going forward. Reversals of write-downs are prohibited. If the inventory recovers in value in a subsequent period, the gain is only realized when the inventory is sold.
• Under IFRS, write-downs to NRV can be reversed (up to the original cost) if conditions change and the inventory recovers value in a subsequent period.

Lower of Cost or Market (LCM) Under U.S. GAAP

Under GAAP, for companies using LIFO or the retail inventory method, the standard prescribes the “lower of cost or market” approach. Here, “market” is strictly defined to avoid mismatches:

• “Market” is the item’s current replacement cost.
• However, there is a “ceiling” equal to NRV (i.e., the item’s NRV should not be exceeded).
• There is also a “floor” equal to NRV minus a normal profit margin.

Therefore, under LCM:

• If replacement cost > NRV → “Market” is capped (ceiling) at NRV
• If replacement cost < NRV minus normal profit margin → “Market” is floored at (NRV – normal profit margin)

The final “designated market” (sometimes called the “replacement cost corridor”) is whichever figure falls within this range:

Ceiling (NRV) ≥ Designated Market (Replacement Cost) ≥ Floor (NRV – Normal Profit Margin)

After determining “designated market,” the final rule is to compare historical cost to this designated market. If the designated market is lower, then the inventory is written down to that lower amount.

Example of LCM for a LIFO Inventory

Assume a retailer uses LIFO. It has a product with: • Historical cost: $100 per unit
• Estimated selling price: $130 per unit
• Estimated completion and disposal cost: $5 per unit
• “Normal” profit margin: $10 per unit
• Current replacement cost: $90 per unit

Step-by-Step:

1. NRV (Ceiling) = $130 – $5 = $125

2. NRV – Normal Profit Margin (Floor) = $125 – $10 = $115

3. Replacement Cost = $90

4. Because $90 (RC) < $115 (Floor), the “designated market” is set to the floor’s level, i.e., $115.

5. The final comparison is:

   Historical Cost ($100) vs. Designated Market ($115).

6. Since the designated market ($115) is higher than cost ($100), no write-down is recognized. The inventory remains at $100.

Effect of LCM on Retailers with Seasonal or Obsolete Goods

In periods of rapidly falling prices or obsolescence, the LCM principle can cause significant write-downs, especially under LIFO or the retail method. Companies must be vigilant about analyzing replacement cost, as well as realistically assessing normal profit margins.

IFRS vs. U.S. GAAP: Key Differences

Below is a summary table highlighting the major differences:

Detailed Example: Applying LCNRV vs. LCM

Below is a comprehensive illustration comparing LCNRV under IFRS or GAAP-FIFO with LCM under GAAP-LIFO.

Scenario

ABC Company, which sells electronics, has two types of inventory, each accounted for differently. For Product X, ABC uses FIFO; for Product Y, ABC uses LIFO.

• Product X (FIFO):
– Cost per unit: $50
– Estimated selling price: $70
– Completion and selling costs: $5
– Normal profit margin: $10 (for perspective)
– Replacement cost: $45

• Product Y (LIFO):
– Cost per unit: $60
– Estimated selling price: $65
– Completion and selling costs: $2
– Normal profit margin: $5
– Replacement cost: $48

Product X (FIFO) – LCNRV Approach

1. NRV = $70 – $5 = $65
2. Comparison:
   – Cost = $50
   – NRV = $65
3. Since NRV > Cost, no write-down is needed. Inventory remains at $50 per unit.

Product Y (LIFO) – LCM Approach

1. NRV (Ceiling) = $65 – $2 = $63
2. Floor = NRV – Normal Profit Margin = $63 – $5 = $58
3. Replacement Cost = $48

Since $48 < $58 (the floor), the designated market is the floor ($58).
4. Compare historical cost ($60) to designated market ($58).
5. The lower of cost or market is $58, so Product Y is written down by $2 per unit (from $60 to $58).

Hence, under GAAP, ABC Company would record no write-down for Product X but a $2/unit write-down for Product Y. Under IFRS, if ABC were using FIFO or Weighted-Average for all products, only the LCNRV approach would apply; the LCM complexity would not come into play.

Practical Insights and Common Pitfalls

1. Consistency in Method Selection
   – Ensure consistent application of LCNRV or LCM based on the inventory cost-flow assumption (e.g., FIFO vs. LIFO). Mixing up the guidance can lead to improper write-down calculations.

2. Frequent Market Conditions Assessments
   – Rapid changes in technology, fashion, or seasonal demand may significantly alter replacement cost, NRV, or normal profit margins. Entities must closely monitor these factors periodically.

3. Robust Documentation
   – Always document assumptions about normal profit margins, selling prices, and disposal costs. Incomplete documentation can raise concerns from auditors.

4. International Operations
   – If a U.S. company has global subsidiaries reporting under IFRS, or if an IFRS-based entity invests in a U.S. entity with LIFO inventory, there may be complexities during consolidation—particularly when reconciling IFRS vs. GAAP approaches.

5. Reversals Under IFRS
   – IFRS reporters must track write-downs carefully to allow reversals if the conditions that led to the write-down no longer exist. This introduces system and process complexities not present under GAAP.

6. Effect on Financial Ratios
   – Write-downs reduce both inventory and net income, impacting metrics such as the current ratio, inventory turnover, and profitability ratios.

Best Practices and Strategies

• Adopt Clear Policies: Companies should maintain explicit documentation outlining how they compute NRV and designated market, including the frequency of updates and the managers involved in the process.
• Implement Regular Obsolescence Reviews: Schedule these reviews to identify slow-moving or unsalable goods early, ensuring timely write-downs and preventing overstated inventory.
• Use Reliable Historical and Market Data: Forecast selling prices and cost of completion/disposal based on well-researched internal data, industry benchmarks, and supplier/commodity price trends.
• Leverage Accounting Software: Many modern ERP systems have integrated modules that automatically calculate LCNRV or LCM based on user-configured parameters, reducing manual errors.
• Stay Informed on Standard Updates: GAAP and IFRS standards can be revised. Keep an eye on pronouncements from the FASB and IASB to ensure continued compliance.

	    K --> L[Choose Lower Value (LCM)]
	    G --> M((End - Inventory Valuation))
	    L --> M((End - Inventory Valuation))

Explanation:
• If the inventory method is FIFO or average cost, a simple LCNRV test applies.
• If the inventory method is LIFO or the retail inventory method, follow the LCM approach, setting the replacement cost within the bounds of a floor and ceiling.

Additional Real-World Considerations

• Retail Industry: Companies that use the retail method can experience frequent price markdowns, especially near the end of a season. LCM adjustments can accumulate quickly, making month-end or quarter-end processes more complex.
• Commodity-Intensive Sectors: Agricultural or mineral-based inventories can see rapid fluctuations in commodity prices, forcing frequent revaluations under LCNRV/LCM.
• High-Tech Firms: Rapid technological obsolescence often drives goods’ NRV below cost, requiring prompt recognition of inventory write-downs.
