1、Chapter 7Reporting and Interpreting Cost of Goods Sold and InventoryANSWERS TO QUESTIONS1. Inventory often is one of the largest amounts listed under assets on the balance sheet which means that it represents a significant amount of the resources available to the business. The inventory may be exces

2、sive in amount, which is a needless waste of resources; alternatively it may be too low, which may result in lost sales. Therefore, for internal users inventory control is very important. On the income statement, inventory exerts a direct impact on the amount of income. Therefore, statement users ar

3、e interested particularly in the amount of this effect and the way in which inventory is measured. Because of its impact on both the balance sheet and the income statement, it is of particular interest to all statement users.2. Fundamentally, inventory should include those items, and only those item

4、s, legally owned by the business. That is, inventory should include all goods that the company owns, regardless of their particular location at the time.3. The cost principle governs the measurement of the ending inventory amount. The ending inventory is determined in units and the cost of each unit

5、 is applied to that number. Under the cost principle, the unit cost is the sum of all costs incurred in obtaining one unit of the inventory item in its present state.4. Goods available for sale is the sum of the beginning inventory and the amount of goods purchased during the period. Cost of goods s

6、old is the amount of goods available for sale less the ending inventory.5. Beginning inventory is the stock of goods on hand (in inventory) at the start of the accounting period. Ending inventory is the stock of goods on hand (in inventory) at the end of the accounting period. The ending inventory o

7、f one period automatically becomes the beginning inventory of the next period.6(a) Average cost-This inventory costing method in a periodic inventory system is based on a weighted-average cost for the entire period. At the end of the accounting period the average cost is computed by dividing the goo

8、ds available for sale in units into the cost of goods available for sale in dollars. The computed unit cost then is used to determine the cost of goods sold for the period by multiplying the units sold by this average unit cost. Similarly, the ending inventory for the period is determined by multipl

9、ying this average unit cost by the number of units on hand.(b) FIFO-This inventory costing method views the first units purchased as the first units sold. Under this method cost of goods sold is costed at the oldest unit costs, and the ending inventory is costed at the newest unit costs.(c) LIFO-Thi

10、s inventory costing method assumes that the last units purchased are the first units sold. Under this method cost of goods sold is costed at the newest unit costs and the ending inventory is costed at the oldest unit costs.(d) Specific identification- This inventory costing method requires that each

11、 item in the beginning inventory and each item purchased during the period be identified specifically so that its unit cost can be determined by identifying the specific item sold. This method usually requires that each item be marked, often with a code that indicates its cost. When it is sold, that

12、 unit cost is the cost of goods sold amount. It often is characterized as a pick-and-choose method. When the ending inventory is taken, the specific items on hand, valued at the cost indicated on each of them, is the ending inventory amount.7. The specific identification method of inventory costing

13、is subject to manipulation. Manipulation is possible because one can, at the time of each sale, select (pick and choose) from the shelf the item that has the highest or the lowest (or some other) unit cost with no particular rationale for the choice. The rationale may be that it is desired to influe

14、nce, by arbitrary choice, both the amount of income and the amount of ending inventory to be reported on the financial statements. To illustrate, assume item A is stocked and three are on the shelf. One cost $100; the second one cost $115; and the third cost $125. Now assume that one unit is sold fo

15、r $200. If it is assumed arbitrarily that the first unit is sold, the gross profit will be $100; if the second unit is selected, the gross profit will be $85; or alternatively, if the third unit is selected, the gross profit will be $75. Thus, the amount of gross profit (and income) will vary signif

16、icantly depending upon which one of the three is selected arbitrarily from the shelf for this particular sale. This assumes that all three items are identical in every respect except for their unit costs. Of course, the selection of a different unit cost, in this case, also will influence the ending

17、 inventory for the two remaining items.8. LIFO and FIFO have opposite effects on the inventory amount reported under assets on the balance sheet. The ending inventory is based upon either the oldest unit cost or the newest unit cost, depending upon which method is used. Under FIFO, the ending invent

18、ory is costed at the newest unit costs, and under LIFO, the ending inventory is costed at the oldest unit costs. Therefore, when prices are rising, the ending inventory reported on the balance sheet will be higher under FIFO than under LIFO. Conversely, when prices are falling the ending inventory o

19、n the balance sheet will be higher under LIFO than under FIFO.9. LIFO versus FIFO will affect the income statement in two ways: (1) the amount of cost of goods sold and (2) income. When the prices are rising, FIFO will give a lower cost of goods sold amount and hence a higher income amount than will

20、 LIFO. In contrast, when prices are falling, FIFO will give a higher cost of goods sold amount and, as a result, a lower income amount.10. When prices are rising, LIFO causes a lower taxable income than does FIFO. Therefore, when prices are rising, income tax is less under LIFO than FIFO. A lower ta

21、x bill saves cash (reduces cash outflow for income tax). The total amount of cash saved is the difference between LIFO and FIFO inventory amounts multiplied by the income tax rate.11. LCM is applied when market (defined as current replacement cost) is lower than the cost of units on hand. The ending

22、 inventory is valued at market (lower), which (a) reduces net income and (b) reduces the inventory amount reported on the balance sheet. The effect of applying LCM is to include the holding loss on the income statement (as a part of CGS) in the period in which the replacement cost drops below cost r

23、ather than in the period of actual sale.12. When a perpetual inventory system is used, the unit cost must be known for each item sold at the date of each sale because at that time two things happen: (a) the units sold and their costs are removed from the perpetual inventory record and the new invent

24、ory balance is determined; (b) the cost of goods sold is determined from the perpetual inventory record and an entry in the accounts is made as a debit to Cost of Goods Sold and a credit to Inventory. In contrast, when a periodic inventory system is used the unit cost need not be known at the date o

25、f each sale. In fact, the periodic system is designed so that cost of goods sold for each sale is not known at the time of sale. At the end of the period, under the periodic inventory system, cost of goods sold is determined by adding the beginning inventory to the total goods purchased for the peri

26、od and subtracting from that total the ending inventory amount. The ending inventory amount is determined by means of a physical inventory count of the goods remaining on hand and with the units valued on a unit cost basis in accordance with the cost principle (by applying an appropriate inventory c

27、osting method).ANSWERS TO MULTIPLE CHOICE司Q49 、，、重，ac38, b、 、,，da27、，）cc165.c)10. a)AuthorsRecommended Solution Time(Time in minutes)Mini-exercisesExercisesProblemsAlternateProblemsCases and ProjectsNo靡TimeNo.TimeNoTimeNo.TimeNo.Time1234567895551055551012345678910111213141516171819202122152020101515

As with any open-ended project, it is

29、 possible for students to devote a large amount of time to these assignments. While students often benefit from the extra effort, we find that some become frustrated by the perceived difficulty of the task. You can reduce student frustration and anxiety by making your expectations clear. For example

30、, when our goal is to sharpen research skills, we devote class time to discussing research strategies. When we want the students to focus on a real accounting issue, we offer suggestions about possible companies or industries.MINI-EXERCISESM7-1.Type of Inventory Work in process Finished goods Mercha
