Chapter 7: Activity-Based Costing and Management 7-27
based costing and activity-based management system to achieve those objectives. After reviewing
documents, interviewing employees, and observing daily operations, you have compiled the
following list of activities:
* Purchase office supplies. Two purchasing agents process approximately 50 purchase orders
per month from 5 vendors. Their salaries total $5,000 each month. Each purchasing agent
uses a computer and other office equipment, and monthly depreciation charges total $300.
The purchasing operation occupies 1,200 square feet of the store’s 8,500 square-foot facility.
Monthly purchases average $2,000, and about 60% of the supplies purchased are sold to
customers. The remaining 40% are used in the store’s operations.
* Provide office space to customers. The store’s main source of revenue is renting office
cubicles to customers. Each cubicle is 200 square feet and contains a desk, chair, filing
cabinet, computer with Internet access, printer, and telephone. Each Offices on the Go site
maintains 15 such cubicles, and the monthly depreciation on cubicle furniture and equipment
totals $500.
* Copy and fax documents for customers. The copy and fax center contains 5 self-service
copiers and 3 fax machines. Monthly depreciation on those items totals $250. The copy and
fax center occupies 1,500 square feet.
* Maintain company operations. Store #2 employs one bookkeeper at a salary of $3,000 per
month and one human resource manager at a salary of $2,800 per month. Their offices
contain the same equipment as the purchasing agents with the same depreciation charges;
both the bookkeeper and the human resource manager occupy 500 square-foot offices.
* Sell office supplies to customers. Office supply displays occupy 1,000 square feet. The
display racks were replaced at a cost of $1,500 last month and were expensed at that time.
* Ring up sales and collect payments. Priscilla employs 10 part-time customer service
representatives. Each representative works between 25 and 30 hours per month at $12 per
hour. The customer service counter and related equipment (such as cash registers) occupy the
remaining 500 square feet.
In addition to costs for the above activities, Store #2 incurs the following costs every month: rent,
$1500; utilities, $600; and maintenance, $800. Each month, 25% of profits are sent to the corporate
office to help cover corporate expenses.
a. Store #2 currently uses a traditional costing system, allocating indirect costs to its three product
lines (office space rental, copy and fax services, and office supplies sales) based on direct labor
hours. Analyze the strengths and weaknesses of the current system from the perspective of the
store manager. Explain why an activity-based costing system will or will not provide better
information for making decisions.
b. Store #2 currently uses a traditional costing system, allocating indirect costs to its three product
lines (office space rental, copy and fax services, and office supplies sales) based on the number of
customers in each area. If an individual customer purchases goods or services from more than
one area, they are counted with the area in which they provide the most revenue. Explain how the
current system is both similar to and different from an activity-based costing system.
c. Activities in an ABC system often are classified as one of six types: organization-sustaining,
facility-sustaining, customer-sustaining, product-sustaining, batch-level, or unit-level. Using the
list above and your own creativity, suggest one example of each activity type for Offices on the
Go. Your organization-sustaining activity should focus on the corporate office; all the others
should be focused on Store #2.
d. List and discuss the steps you would use to assign costs in Store #2’s ABC system.
e. One of the steps in designing an ABC system is assigning costs to ABC cost pools. Another step
is selecting a cost driver for each pool. Based on the preceding narrative, suggest two cost pools
