The lower of cost and net realizable value can be applied to individual inventory items or groups of similar items, as shown in Figure 6.15 below. Instead of the $2,000 that was reported, the correct value should have been $1,000. The effect of this error was to understate cost of goods sold on the income statement — cost of goods sold should have been $21,000 in 2022 as shown below instead of $20,000 as originally reported above.

Can you give an example of how FIFO and LIFO affect a grocery store's financial reporting?

Unfortunately, for many other types of inventory, no practical method exists for determining the physical flow of merchandise. All of the preceding issues are of less importance if the weighted average method is used. This approach tends to yield average profit inventory accounting levels and average levels of taxable income over time. Generally accepted accounting principles (GAAP), a common set of accounting principles, standards, and procedures that all public companies in the U.S. are required to abide by, champions consistency.

• It can be used when items are consistently valued at a known percentage of cost, known as a mark-up.
• LIFO is now not allowed in Canada under IFRS or ASPE, but it is still used in the United States.
• Each unit that is sold is specifically identified, and the cost for that unit is allocated to cost of goods sold.
• If white paper and coloured paper are considered a similar group, the calculations in Figure 6.15 above show they have a combined cost of $2,650 and a combined net realizable value of $2,700.
• Note that the sales price is not affected by the cost assumptions; only the cost amount varies, depending on which method is chosen.
• Generally, the units are physically removed from inventory by selling the oldest units first.

Periodic Inventory Method

Then, on December 31, Year One, a customer buys one of these two shirts by paying cash of $110. Regardless of the cost flow assumption, the company retains one blue dress shirt in inventory at the end of the year and cash of $110. The average cost flow assumption eliminates the need to track each individual item, which can come in handy, particularly when there are large volumes of similar goods moving through inventory. This technique requires minimal labor, is much cheaper than other inventory cost methods to apply, and, in theory, is less likely to manipulate income. To apply the retail inventory method using the mark-up percentage, the cost of goods available for sale is first converted to its retail value (the selling price).

What is the premise of the Average Cost method in inventory accounting?

This method would thus achieve the perfect matching of costs to the revenue generated. First, unless items are easy to physically segregate, it may difficult to identify which items were actually sold. As well, although physical segregation may be possible, this method could be expensive to implement, as a great deal of record keeping is required. The second disadvantage of this method is its susceptibility to earnings-management techniques.

Averages unit costs, mitigates price fluctuation impact, balances FIFO and LIFO outcomes. As an example, a change in consumer demand may mean that inventories become obsolete and need to be reduced in value below the purchase cost. This often occurs in the electronics industry as new and more popular products are introduced.

Financial statements are expected to be easily comparable from one accounting period to the next to make life simpler for investors. The purpose of the adjusting entry is to ensure that inventory is not overstated on the balance sheet and that income is not overstated on the income statement. The ______ method allocates costs to the oldest inventory, while ______ assigns costs to the most recent purchases. The ______ accounting method is based on the assumption that the earliest inventory added is the first to be sold. The ______ on the balance sheet may appear inflated due to FIFO valuing inventory at more recent, ______ prices. The last cost incurred in buying two blue shirts was $70 so that amount is reclassified to expense at the time of the first sale.

Therefore, a moving average system must be programmed to update the average whenever additional merchandise is acquired. Note that with the perpetual LIFO example above dates are even more important because with LIFO a new purchase of inventory will become the items sold so whether that purchase happened before or after the sale will change our calculations. Inventory Cost Flow Assumptions in accounting are essential for managing inventory valuation and financial reporting. They include FIFO, LIFO, Average Cost, and Specific Identification methods, each affecting a company's profitability and tax burden differently. Understanding these methods is key for accurate financial analysis and strategic decision-making in business management. Suppose you are the assistant controller for a retail establishment that is an independent bookseller.

Proponents of LIFO argue that matching the December 29 cost with the December 31 revenue is more appropriate than using a cost incurred months earlier. According to this reasoning, income is more properly determined with LIFO because a relatively current cost is shown as cost of goods sold rather than a figure that is out-of-date. “By matching current costs against current sales, LIFO produces a truer picture of income; that is, the quality of income produced by the use of LIFO is higher because it more nearly approximates disposable income” (Rumble, 1983). Note that it is not the oldest item that is necessarily sold but rather the oldest cost that is reclassified to cost of goods sold. No attempt is made to determine which shirt was purchased by the customer.

Average Cost Flow Assumption vs. FIFO vs. LIFO

The retail inventory method of estimating ending inventory is easy to calculate and produces a relatively accurate cost of ending inventory, provided that no change in the average mark-up has occurred during the period. As can be seen, income is misstated in both 2022 and 2023 because cost of goods sold in both years is affected by the adjustment to ending inventory needed at the end of 2020 and 2021. The opposite effects occur when inventory is understated at the end of an accounting period. Choosing an inventory cost flow method should align with company operations and market conditions. Methods like ______, ______, and ______ are based on assumptions of cost allocation, not on the actual movement of inventory items.
