Relevant Costs for Decision Making UAA – ACCT 202 Principles of Managerial Accounting Dr. Fred Barbee
Information as a Resource Information is now regarded as the sixth resource.
Information Anxiety Source: Information Anxiety Richard S. Wurman
A weekend edition of the NY Times contains more information than the average person was likely to come across in a lifetime in seventeenth-century England.
More new information has been produced in the last 30 years than in the previous 5, 000. About 1, 000 books are published internationally every day, and the total of all printed knowledge doubles every eight years.
In a single year. . . • The average American will read or complete 3, 000 notices and forms; • Read 100 newspapers and 36 magazines; • Watch 2, 463 hours of television;
In a single year. . . • Listen to 730 hours of radio; • Talk on the phone for 61 hours; and • Read 3 books

Information Overload The theory of bounded rationality (Simon, 1955). Humans are organisms of limited knowledge and computational capacity. Thus, simplifications (heuristics) are deliberately introduced into the choice mechanism.
Dealing With Information Overload HELP!
Information Processing • People are consistency seekers; • People are Information Processors; and • People are Cognitive Misers
People as Information Processors • Actively seek out information, • Observe facts, and • Reason
People as Cognitive Misers • Minimize cognitive efforts, and • Take shortcuts.
Managers as Cognitive Misers • Managers must be selective in the kinds of information they request. • The key to limiting the flow of data is to request only relevant information.
Information Overload • Unquestionably we need information in our lives. . . however, that information must be directly relevant to our daily lives. • The real question today is, “How do we zero in on the relevant and reject the rest? ”
Information Literacy To be information literate, a person must be able to recognize when information is needed and have the ability to locate, evaluate, and use effectively the needed information. Source: Presidential Committee on Information Literacy
The Need For Cost Data • Purchase new equipment; • Replace existing equipment; • Introducing new products; • Taking special orders;
The Need For Cost Data • Make vs. buy decisions. • Product-pricing decisions • Allocation of scarce resources.
Relevant Costs Are. . . • Any cost that differs among alternatives and will influence the outcome, • Any cost that is avoidable, and avoidable • Any cost that is a future cost.
Relevant Revenues • Any revenue that differs among alternatives; and • will influence the outcome,
Avoidable Costs An avoidable cost is. . . a cost that can be eliminated (in whole or in part) as a result of choosing one alternative over another.
Avoidable Costs • All costs are considered to be avoidable, except. . . – Sunk Costs, and – Costs that are the same for each alternative.
When does the cost arise? Past Does the cost differ between alternatives? Yes No Future Sunk Relevant Sunk Not Relevant

Identifying Relevant Costs A Text Example
Identifying Relevant Costs Text pages 588 -589
Identifying Relevant Costs Option #1 Option #2 From a financial standpoint, Cynthia would be better off taking the train to visit her friend. Some of the non-financial factor may influence her final decision.
Total and Differential Cost Approaches The Text Example
Text Example • Oak Harbor Woodworks is considering a new labor-saving machine that rents for $3, 000 per year. • The machine will be used on the company’s butcher block production line. • Pertinent data are provided.
Text Example Text pages 591
Exhibit 13 -1 – Total and Differential Costs
Adding and Dropping Product Lines and Other Segments Exercise 13 -3 p. 613
What should Jackson do? Decision Rule Jackson County should drop the housekeeping segment only if its profit would increase. This would happen only if the fixed cost savings exceed the lost contribution margin.
Incremental (Differential) Analysis Contribution Margin lost if program is dropped ($80, 000) Fixed costs avoided: Liability Insurance Administrator’s Salary Decrease in NOI for firm as a whole $15, 000 37, 000 52, 000 ($28, 000)
This same solution can be obtained by using a total cost approach by preparing comparative income statements showing results with and without the Housekeeping segment.
The Total Cost Approach Depreciation is a sunk cost and the van has no salvage value since it would be donated to another organization. General Administrative overhead is allocated and none of it would be avoided if the program is dropped.
Let’s apply that concept to this problem BEWARE OF ALLOCATED FIXED COSTS! Remember the text discussion of this topic?
Beware of Allocated Fixed Costs
The Make or Buy Decision
The Make or Buy Decision • A decision concerning whether an item should be produced internally or purchased from an outside supplier is called a “make or buy” decision. • Exercise 13 -4 – Make or Buy a Component (p. 614)
The Make or Buy Decision • A decision concerning whether an item should be produced internally or purchased from an outside supplier is called a “make or buy” decision.
The Make or Buy Decision • In the “make vs. buy” decision you need to isolate the relevant costs by: – Eliminating the sunk costs – Eliminating future costs that do not differ between the make or buy decision. • Exercise 13 -4 – Make or Buy a Component (p. 614).
Opportunity Costs
Special Orders
Special Orders • A special order is a one-time order that is not considered part of the company’s normal ongoing business. • Before acceptance the firm must carefully examine existing capacity. • Exercise 13 -5 – Evaluating a Special Order.
Utilization of a Constrained Resource
Constrained Resources • Maximize total contribution margin by promoting those products/orders that provide the highest unit contribution margin in relation to the constrained resource. • Exercise 13 -6 – Utilization of a constrained resource.
Managing Constraints Produce only what can be sold. At the bottleneck itself: • Improve the process • Add overtime or another shift • Hire new workers or acquire more machines • Subcontract production Eliminate waste. Streamline production process.
Joint Product Costs
Joint Product Costs • In some industries, a number of end products are produced from a single raw material input. • Two or more products produced from a common input are called joint products. • The point in the manufacturing process where each joint product can be recognized as a separate product is called the split-off point.
Joint Products Joint Costs Joint Input Common Production Process Oil Gasoline Chemicals Split-Off Point Separate Processing Final Sale Separate Processing Separate Product Costs Final Sale
The Pitfalls of Allocation Joint costs are really common costs incurred to simultaneously produce a variety of end products. Joint costs are often allocated to end products on the basis of the relative sales value of each product or on some other basis.
