Which inventory valuation method assigns the most recent costs to the cost of goods sold and the oldest costs to ending inventory, often resulting in lower taxes in times of rising prices?
First-In, First-Out (FIFO)
Last-In, First-Out (LIFO)
Weighted Average Cost
Specific Identification
Correct Answer:B
Explanation
The correct option is B. Last-In, First-Out (LIFO).
Detailed Explanation
Understanding Inventory Valuation Methods:
Inventory valuation methods are used to determine the cost of goods sold (COGS) and the value of ending inventory. The choice of method can significantly impact financial statements and tax liabilities.
LIFO Explained:
Last-In, First-Out (LIFO) assumes that the most recently purchased inventory items are sold first. This means that during periods of rising prices, the costs associated with the most recent purchases (which are higher) are recorded as COGS.
As a result, the older, lower-cost inventory remains in ending inventory. This leads to a lower net income because higher costs are matched against revenues, which can result in lower taxes owed.
Example Calculation:
Suppose a company has the following inventory purchases:
100 units at $10 each (oldest)
100 units at $12 each (newest)
If the company sells 150 units, under LIFO, the COGS would be calculated as follows:
Sell 100 units from the $12 batch: 100 units x $12 = $1,200
Sell 50 units from the $10 batch: 50 units x $10 = $500
Total COGS = $1,200 + $500 = $1,700
Ending inventory would consist of:
50 units from the $10 batch (remaining) = 50 units x $10 = $500
100 units from the $10 batch (oldest) = 100 units x $10 = $1,000
Total ending inventory = $1,000 + $500 = $1,500
Why Other Options Are Incorrect:
A. First-In, First-Out (FIFO):
FIFO assumes that the oldest inventory items are sold first. In times of rising prices, this results in lower COGS (because older, cheaper costs are matched against revenues) and higher net income, leading to higher taxes.
C. Weighted Average Cost:
This method averages the cost of all inventory items available for sale during the period. It does not specifically assign the most recent or oldest costs to COGS or ending inventory, which means it does not provide the tax benefits associated with LIFO in rising price environments.
D. Specific Identification:
This method tracks the actual cost of each specific item sold. While it can be very accurate, it does not inherently favor recent or older costs and is not typically used for large volumes of similar items. It does not provide the same tax advantages as LIFO in inflationary periods.
Common Pitfalls
Students often confuse FIFO and LIFO, especially regarding their impact on taxes and net income during inflation.
It’s important to remember that LIFO is not allowed under International Financial Reporting Standards (IFRS), which can lead to confusion in global contexts.
Revision Summary
LIFO assigns the most recent costs to COGS and the oldest costs to ending inventory.
In rising price environments, LIFO results in lower net income and lower taxes.
FIFO results in higher net income and higher taxes during inflation.
Weighted Average and Specific Identification do not provide the same tax benefits as LIFO.
