Chapter E, Problem E.6E

1.

To determine

To Calculate: The ending inventory, cost of goods sold, and gross profit for 2018, assuming the Company uses LIFO with a periodic inventory system.

Answer to Problem E.6E

The ending inventory, cost of goods sold, and gross profit for 2018 under LIFO with a periodic inventory system are $6,660, $23,130, and $3,870 respectively.

Explanation of Solution

Periodic Inventory System:

Periodic inventory system is a system in which the inventory is updated in the accounting records on a periodic basis such as at the end of each month, quarter or year. In other words, it is an accounting method which is used to determine the amount of inventory at the end of each accounting period.

Last-in-Last-Out:

In Last-in-First-Out method, the costs of last purchased items are considered as the cost of goods sold, for the items which are sold first. The value of the closing stock consists of the initial purchased items.

Calculate the ending inventory, cost of goods sold, and gross profit for 2018 under LIFO method.

Calculate the Cost of Ending Inventory.

LIFO Method
Date	Transaction	Units (a)	Unit Cost (in $) (b)	Total Cost (in $) $\left(\text{c}\right)=\left(\text{a}\right)\times \left(\text{b}\right)$
January 1	Beginning inventory	70	83	5,810
April 7	Purchase	10	85	850
	Total	80		6,660

To determine

To Calculate: The ending inventory, cost of goods sold, and gross profit for 2018, assuming the Company using FIFO.

Answer to Problem E.6E

The ending inventory, cost of goods sold, and gross profit for 2018 under FIFO with a periodic inventory system are $6,960, $22,830, and $4,170 respectively.

Explanation of Solution

Periodic Inventory System:

Periodic inventory system is a system in which the inventory is updated in the accounting records on a periodic basis such as at the end of each month, quarter or year. In other words, it is an accounting method which is used to determine the amount of inventory at the end of each accounting period.

First-in-First-Out:

In First-in-First-Out method, the costs of the initially purchased items are considered as cost of goods sold, for the items which are sold first. The value of the ending inventory consists of the recent purchased items.

To determine

To Explain: The effects in the Company’s income statement and balance sheet of using FIFO instead of LIFO to account for inventory.

Explanation of Solution

The effects in the Company’s income statement and balance sheet of using FIFO instead of LIFO to account for inventory are as follows:

• As the gross profit under FIFO method is higher ($4,170) than LIFO method ($3,870), using FIFO method instead of LIFO method to account for inventory results in higher income of $300 $\left(\$4,170-\$3,870\right)$.
• Similarly, as the ending inventory under FIFO method is higher ($6,960) than LIFO method ($6,660), using FIFO method instead of LIFO method to account for inventory results in higher assets of $300 $\left(\$4,960-\$4,660\right)$.
