Learning Unit 11–1: Adjustments for Merchandise Inventory Using
the Perpetual Method, Unearned Rent, Supplies Used, Insurance
Expired, Depreciation Expense, and Salaries Accrued
Summary: The Merchandise Inventory account shows the goods that a merchandise company has
available to sell to customers. Companies have several ways to keep track of the cost of goods sold (the
total cost of the goods sold to customers) and the quantity of inventory on hand. The two systems are the
periodic inventory system and perpetual inventory system. The perpetual inventory system is an
inventory system that keeps continual track of each type of inventory unit by recording units on hand at
the beginning, units sold, and the current balance after each sale or purchase.
Key Concepts: Cost of goods sold, perpetual inventory system, beginning merchandise inventory
(beginning inventory).
Lecture Outline:
Adjustments for merchandise inventory: Businesses can choose either to track the cost of goods sold
using a perpetual inventory system or a periodic inventory system:
1. Perpetual inventory system continually updates the balance of inventory on hand.
2. Adjusting entries to update the value of the inventory to the value of the inventory actually on
hand:
a. Adjusting journal entry for inventory shrinkage:
3. Adjusting entries are required when rent is received in advance of earning the rent. Unearned
Rent is a liability account which is used to record rent received in advance. When rent is earned,
then the amount earned needs to be credited to Rent Revenue and debited to Unearned Rent.

Learning Unit 11-2: Worksheets for Merchandise Companies Using
the Perpetual Inventory Method
Summary: In this unit we prepare a worksheet for Art’s Wholesale Clothing Company. For convenience,
we reproduce the company’s chart of accounts in Figure 11.3, and Figure 11.4 which shows the trial
balance that was prepared from Art’s Wholesale ledger. In looking at the trial balance, we see many new
titles that did not appear in the trial balance which we completed for a service company in Chapter 5.
Examples are mortgage payable, interest expense, and unearned revenue. Mortgage Payable is a
liability account that records the increases and decreases in the amount of debt owed on a mortgage.
