What Are Cost Flow Assumptions?

It breaks down each transaction so you can see and understand precisely how Pinky’s perpetually tracks the inventory. Here is an example of a small business using the FIFO and LIFO methods. For example, a tanker delivers 2,000 gallons of gasoline to Henry’s Service Station on Monday. This system is preferred by most companies, but it is especially used in companies where the inventory is perishable Accounting Periods and Methods or subject to quick obsolescence. Because the ending inventory of one period becomes the beginning inventory of the next period, a misstatement in inventory will affect both periods. Inventory is considered a current asset because it normally is sold within one year or the operating cycle . Assume the same facts as problem 1 above, except that SuperDuper has decided to use averaging.

The choice to use one of the three cost flow assumptions has been part of the U.S. tax code ever since LIFO was introduced in the Revenue Act of 1938. However, lawmakers have recently targeted LIFO for repeal as a means to raise revenue or as a part of broader tax reform. This would restrict companies to either FIFO or Weighted-Average Cost. In 2013, Representative Dave Camp introduced a tax reform proposal, which would have eliminated Last-in, First-out for inventories. The same year, former Senator Max Baucus proposed eliminating LIFO for companies.

Accounting & Inventory

The use of LIFO would produce a higher ending inventory, a lower cost of goods sold, and a higher gross profit than FIFO. When costs fluctuate, no general relationships can be described. Many arguments are made in favor of each of the alternative cost flow assumptions.

  • The goods are sold to make a gross profit of 50% on original cost.
  • This statement is true for some one-of-a-kind items, such as autos or real estate.
  • Depreciation, as just one example, is computed in an entirely different manner for tax purposes than for financial reporting.
  • If the forecast indicates that the company will not liquidate any inventory at the end of the year, it removes the effect of the LIFO liquidation from the interim financial statements.
  • To choose a cost accounting method, companies should first understand how the different methods will change their balance sheets and income statements.

In addition, various accounting practices, such as alternative cost flow assumptions and valuation principles, are widely used and may have a significant effect on asset valuation and income determination. U.S. GAAP tends to apply standard reporting rules for many transactions to make financial statements more usable by decision makers.

Thought On comparison Between Different Cost Flow Assumptions

Return on assets, also known as net income divided by average assets, look better under LIFO than FIFO. A periodic LIFO inventory system begins by computing the cost of ending inventory at the end of a period and then uses that figure to calculate cost of goods sold. Perpetual LIFO also transfers the most recent cost to cost of goods sold but makes that reclassification at the time of each sale. A weighted average inventory system determines a single average for the entire period and applies that to both ending inventory and the cost of goods sold. A moving average system computes a new average cost whenever merchandise is acquired. That figure is then reclassified to cost of goods sold at the time of each sale until the next purchase is made.

However, the higher net income means the company would have a higher tax liability. That means that it is not possible to frequently chop and change inventory costing methods. Regular alterations are frowned upon and, when necessary, must clearly be highlighted in the company’s footnotesto the financial statements.

Why choose any individual cost if no evidence exists of its validity? If items with varying costs are held, using an average provides a very appealing logic. In the shirt example, the two units cost a total of $120 ($50 plus $70) so the average is $60 ($120/2 units). According to OrderMetrics, the inventory method a company uses affects its costs of goods sold, or COGS, which has an impact on bookkeeping its profitability ratios. The formula for COGS is beginning inventory plus purchases less ending inventory. A company using FIFO to value its inventory reports lower COGS, which increases its gross profit margin, also known as sales less COGS, and its net income all else being equal. A company using LIFO reports higher COGS, translating into lower gross profit, net income and profit margins.

In the illustration, the units in yellow illustrate the 5 units that would be sold if using the LIFO cost flow assumption. Given that the units in yellow are the ones sold, the units in green will make up the ending inventory at the end of the period. The first in, first out inventory method is based on the assumption that the units purchased first are sold first, therefore leaving the most recently purchased units in ending inventory. The flow of costs under the FIFO method typically follows what is considered a traditional way to think of how goods flow. The first units that are purchased, from a physical flow perspective, would be the first units that would be deemed to be sold. Therefore, when cycling in new units, it’s important to sell the older ones first.

The cost flow assumption that a business makes may have nothing to do with the actual flow of inventory into and out of the business. The physical flow of goods refers to the actual timing of when goods are sold.

What Is Inventory?

The U.S. tax code currently allows businesses to choose the method by which they account for inventories. Repealing Last-in, First-out accounting moves the tax code further from neutrality and raises the cost of capital. LIFO repeal would fly in the face of one of the goals of tax reform, which is to allow businesses to fully and immediately expense any investments it makes, including inventories.

The larger the cost of goods sold, the smaller the net income. Those who favor LIFO argue that its use leads to a better matching of costs and revenues than the other methods. When a company uses LIFO, the income statement reports both sales revenue and cost of goods sold in current dollars. The resulting gross margin is a better indicator of management ‘s ability to generate income than gross margin computed using FIFO, which may include substantial inventory profits.

This method is far too cumbersome for companies with large and even medium-sized inventories, although it is the most precise way of determining inventory prices. As a result, other inventory valuation methods have been developed. • The calculation of a cost index is necessary to convert the inventory to base-year costs so that quantity increases may be isolated from cost increases . • Inventory is often included in one or more inventory pools to keep the advantages of LIFO when there are fluctuations in the physical quantities of similar products and/or technological change. • If a company has a LIFO liquidation in an interim reporting period but expects to replace the inventory by year-end, the impact of the liquidation is removed from its interim financial statements.

Periodic FIFO and perpetual FIFO systems arrive at the same reported balances because the earliest cost is always the first to be transferred regardless of the method being applied. Companies have several methods at their disposal to roughly figure out which costs are removed from a company’s inventory and reported as COGS. This particular approach takes an average of the cost of items sold, leading to a mid-range COGs figure. Explain the fundamental cost flow assumptions of the average cost, FIFO, and LIFO inventory cost flow methods.

The first‐in, first‐out method yields the same result whether the company uses a periodic or perpetual system. Under the perpetual system, the first‐in, first‐out method is applied at the time of sale. The earliest purchases on hand at the time of sale are assumed to be sold.

This is because taxable income under LIFO is higher than it is under FIFO when prices fall. The LIFO reserve also diminishes when the level of inventory drops, and would disappear if inventories were reduced to zero. Inventory turnover ratio vary significantly among industries. A high ratio indicates fast moving inventories and a low ratio, on the other hand, indicates slow moving or obsolete inventories in stock. A low ratio may also be the result of maintaining excessive inventories needlessly.

This occurs when the number of units in ending inventory is less than the number in beginning inventory because unit sales are more than the units acquired during the period. Therefore, some of the beginning inventory costs are included in cost of goods sold. In other words, the layers of LIFO inventory costs added in previous periods are removed in reverse order; the last costs added are the first expensed. Assuming rising costs, these units have lower costs attached to them; thus cost of goods sold is lower and gross profit is higher than if the liquidation did not occur. This increased amount of income is often referred to as a LIFO liquidation profit. Many companies adopted LIFO in 1939 when the method was first allowed to be used by all companies for income tax purposes, and also in the higher inflation period between 1975 and 1985. Therefore, a company’s LIFO liquidation profit may be significant because it includes some very old costs in cost of goods sold.

Under current law, companies that purchase capital investments lose the value of the deductions due to their delay. Suppose a business purchases a $1000 machine and is required to deduct it over five years . The sum of the nominal deductions will be $1000, but the sum of each year’s present-value deductions will only equal $809 (at a 5 percent discount rate normal balance and 2.5 percent inflation). Although the business spent $1000 up front on the machine, it only ended up being able to deduct 80.9 percent of the value of its true cost. This means that a company that uses LIFO for many years or decades can build a substantial LIFO reserve. However, if prices begin to fall a company’s LIFO reserve will start to diminish.

Impact On The Financial Statements

The six inventory systems shown here for Mayberry Home Improvement Store provide a number of distinct pictures of ending inventory and cost of goods sold. As stated earlier, these numbers are all fairly the assumption that a company makes about its inventory cost flow has presented but only in conformity with the specified principles being applied. In contrast, a perpetual system maintains an ongoing record of the goods that remain on hand and those that have been sold.

If inventory is not properly measured, expenses and revenues cannot be properly matched and a company could make poor business decisions. There a two methods to estimate inventory cost the retail inventory method and the gross profit method.

Moving Average Cost

However, companies may ignore these adjustments if the effects are not material. As we discuss in Chapter 18, what a company includes in inventory depends on its revenue recognition decisions.

Methods Used To Estimate Inventory Cost

A merchandising company can prepare an accurate income statement, statements of retained earnings, and balance sheets only if its inventory is correctly valued. On the income statement, a company using periodic inventory procedure takes a physical inventory to determine the cost of goods sold. Since the cost of goods sold figure affects the company’s net income, it also affects the balance of retained earnings on the statement of retained earnings. On the balance sheet, incorrect inventory amounts affect both the reported ending inventory and retained earnings. Inventories appear on the balance sheet under the heading ” Current Assets,” which reports current assets in a descending order of liquidity. Because inventories are consumed or converted into cash within a year or one operating cycle, whichever is longer, inventories usually follow cash and receivables on the balance sheet. Conversely, dramatic changes in inventory costs over time will yield a considerable difference in reported profit levels, depending on the cost flow assumption used.

Under this procedure, the inventory composition and balance are updated with each purchase and sale. Each time a sale occurs, the items sold are assumed to be the most recent ones acquired.

FIFO is the preferred accounting method in an environment of rising prices. If the inventory market prices go up, FIFO will give you a lower cost of goods sold because you are recording the cost of your older, cheaper goods first. From a tax perspective, the Internal Revenue Service requires that you use the accrual method of accounting if you have inventory. Unlike the other cost flow systems, specific identification does not follow any specific pattern or assumptions. The difference between yellow and green units designates the specialized difference between otherwise identical products.

The only requirement when choosing a method is that at the end of the period, the sum of COGS and ending inventory equals the cost of goods available. Inventory costing, also called inventory cost accounting, is when companies assign costs to products.

Typically, financial reporting and the preparation of income tax returns are unrelated because two sets of rules are used with radically differing objectives. However, the LIFO conformity rule joins these two at this one key spot. The last in, first out inventory method is based on the assumption that the units purchased more recently are sold first, therefore leaving the units purchased first in ending inventory.
