Chapter 5 - Activity-Based Costing and Customer Profitability Analysis
5-42 (continued-1)
The budgeted unit costs per pound are:
Mona Loa Coffee Malaysian Coffee
Direct unit costs:
Direct materials $4.20 $3.20
Direct labor 0.30 $4.50 0.30 $3.50
Indirect unit costs:
Purchasing 0.02 1.00
(4 orders × $500 ÷ 100,000 lbs.) (4 orders × $500 ÷ 2,000 lbs.)
Quality control 0.02 0.40
(10 batches × $200 ÷ 100,000 lbs.) (4 batches × $200 ÷ 2,000 lbs.)
Roasting 0.10 0.10
(1,000 hours × $10 ÷ 100,000 lbs.) (20 hours × $10 ÷ 2,000 lbs.)
Blending 0.05 0.05
(500 hrs.× $10 ÷ 100,000 lbs.) (10 hrs.× $10 ÷ 2,000 lbs.)
The comparative cost numbers are:
Mona Loa Malaysian
Requirement 1 $6.00 $5.00
Requirement 2 4.82 7.46
The ABC system in requirement 2 reports a decreased cost for the high-
volume Mona Loa and an increased cost for the low-volume Malaysian.

3. Three of the indirect cost items can be classified as output-unit driven:
Mona Loa
Coffee
Malaysian
Coffee
Roasting $0.10 $0.10
Blending 0.05 0.05
The other three indirect cost items are batch-level driven:
Mona Loa
Coffee
Malaysian
Coffee
Purchasing $0.02 $1.00
Material handling 0.12 2.40
Malaysian coffee has a greater number of setups per output unit than
does Mona Loa coffee. The result is that the unit cost of the lower-
volume Malaysian coffee is much higher than that of the higher-volume
coffee, even though its cost of direct materials is lower.
With the current costing system, the high-volume Mona Loa is
overcosted, while the low-volume Malaysian is undercosted. Pricing of
Mona Loa can be reduced to make it more competitive. In contrast,
Malaysian should be priced at a much higher level if the strategy is to
cover the current period’s cost. CBI may wish to have lower margins
with its low-volume products such as Malaysian in an attempt to build

ABC cost data also point out that the reason for the Malaysian
coffee to have a higher unit cost is not because of high-priced
ingredients. In fact, Malaysian coffee has a lower cost of direct
materials than that of Mona Loa coffee. The costs of roasting, blending,
and packaging are $0.16 per pound for both coffees. The higher cost of
Malaysian is because of the way in which it is processed. The batch-

2. The information on cost of capacity can alert management to the total cost
of unused capacity, in this case $432,230 or approximately 14% of total
overhead cost. This information can be used to identify activities where there
is extensive over-capacity, and to consider how the capacity might be

equal share to the work of the activity. Note that the materials handling
activity appears to have as many as 5 unused employees.

Calculation for general administration allocated to branches:
Total direct labor dollar: $382,413 + $317,086 + $317,188 = $1,016,687
Allocation of general administration based on direct labor dollar:
Proportion Allocated Amount
Columbus $382,413 ÷ $1,016,687 = 37.61% $409 × 37.61% = $153.82
Dayton $317,188 ÷ $1,016,687 = 31.20% $409 × 31.20% = $127.60

4. Evaluating management concerns:
Overhead costs are usually aggregated in pools and allocated to
products and other cost objects based on volume measures such as
direct labor dollars or machine hours. The cost object, therefore,
supposedly shares proportionally in those costs necessary for its
production or existence. If however, overhead varies in accordance with
variables other than volume, then product costs and other cost objects
will be erroneously determined.
As the solution indicates, the profitability of the Cincinnati and Dayton
offices is vastly different employing direct tracing and ABC than under
the current approach. The obvious benefit to the company is a more
concerning relative profitability.
This case also illustrates that ABC is applicable to service organizations
as well as to manufacturing and that cost objects can consist of projects,
locations, customers, etc., as well as products. In essence, the better

Analysis of the Differences
Under the current costing system, ADA applies overhead based on direct
labor hour, and high-volume products such as Diomycin (1,000,000
capsules) are allocated relatively more overhead ($90,000) than the low-
volume products such as Addolin (300,000 capsules). High-volume
products “subsidize” low-volume products in this case. Because of lack of
