DESCRIPTIONS OF PROBLEMS AND CRITICAL THINKING CASES
24.1 A,B
Bradley/Undem 25 Strong
Materials variances must be computed with missing data. The problem
requires an understanding of relationships among variances, including a
volume variance.
24.2 A,B
AgriChem Industries/Dyelot Industries 30 Medium
Compute cost variances for direct materials, direct labor, and overhead,
and prepare journal entries to record manufacturing costs in a standard
cost system.
24.3 A,B
American Hardwood Products/Latin Silk Products 25 Medium
Prepare journal entries to record cost variances and the costs incurred in
the Work in Process account. Also record cost of units completed and
cost of units sold. Compute fixed manufacturing overhead.
24.4 A,B
Sven Enterprises/Hans Enterprises 45 Strong
A comprehensive problem requiring knowledge of all variances and
corresponding journal entries.
24.5 A,B
Slick Corporation/Smooth Corporation 45 Strong
A comprehensive problem requiring knowledge of all variances and
corresponding journal entries.
24.6 A,B
Polyglaze, Inc./Monoglut, Inc. 40 Strong
Compute cost variances and prepare journal entries to record the flow of
manufacturing costs through a standard cost accounting system.
24.7 A,B
Heritage Furniture Co./Colonial Furniture Co. 40 Strong
A comprehensive standard cost problem. Requires computation of cost
variances, journal entries, and an analysis of the company’s strengths and
weaknesses.
24.8 A,B
Ripley Corporation/Foding Corporation 60 Strong
This is a comprehensive problem with missing data. An analytical
approach is required. This would be an excellent problem to assign to
small groups or to teams of students.
24.9 A,B
Anton Company/Ninna Company 45 Medium
Below are brief descriptions of each problem and case. These descriptions are accompanied by the
estimated time (in minutes) required for completion and by a difficulty rating. The time estimates
assume use of the partially filled-in working papers.
Problems (Sets A and B)
Given budget items and a variance report, the student is asked to solve
for various actual amounts. Also, the meaning of favorable and
unfavorable variances must be applied. A good comprehensive review
problem well suited for a group assignment.
Critical Thinking Cases
24.1
It’s Not My Fault 25 Strong
Cabinets, Inc.
In a company using standard costs and a responsibility cost accounting
system, who should be charged with the responsibility for unfavorable
labor rate variances incurred when the production department works
overtime to fill “rush” orders?
24.2
Armstrong Chemical 50 Strong
Evaluate arguments given by the president of a company against the
revision of standard costs and the value assigned to inventory. Assuming
that standards for the year just ended should be revised, determine the
value of ending inventory using revised standard costs.
24.3 Travelocity.com 30 Medium
Internet
Students are given a budgeted amount for travel to a given destination.
Using actual ticket prices obtained from travelocity.com they calculate a
current spending variance. Factors that might affect the reasonability of
the budgeted amount are also discussed.
24.4 Standard Cost Systems and Inventory Misstatements 30 Medium
Ethics, Fraud & Corporate Governance
Jams and Jellies, Inc.
The ethical problems created by inappropriate standards are explained.

If Loring's standards are reasonable, it appears that employees are not working as
efficiently as the company would like (they used 7,500 actual hours rather than 6,250
Managers using ideal standards would expect unfavorable variances on a regular
The normal or expected hours are higher than the actual hours billed. Furthermore,
the actual expenditures were less than expected. The actual, budgeted, and applied
overhead are:

Given that Ringo incurred actual overhead costs of $10,500, applied overhead
costs of $9,000, and reported a $2,000 unfavorable overhead spending variance
for the period, we can construct the diagram shown below:
