1. Contrôle Interne Avancé-HEC Lausanne-2007/2008 1 Thème 9: Decision Making and Relevant Information

2. Contrôle Interne Avancé-HEC Lausanne-2007/2008 2 Define differential costs and sunk costs Before making a decision, the associated costs and revenues related to each decision must be identified. The costs and revenues that are different for alternatives are relevant to each alternative.  Differential costs: future costs that change as a result of a decision.  Sunk costs: past costs that cannot be changed by current and future decisions; disregarded when determining the differential costs of a project. Before making a decision, the associated costs and revenues related to each decision must be identified. The costs and revenues that are different for alternatives are relevant to each alternative.  Differential costs: future costs that change as a result of a decision.  Sunk costs: past costs that cannot be changed by current and future decisions; disregarded when determining the differential costs of a project.

3. Contrôle Interne Avancé-HEC Lausanne-2007/2008 3 Three different approaches to decision making Differential Costs: Only the costs unique to each alternative are identified. Total Cost: All costs are identified with each alternative. Qualitative Considerations: Factors that affect a decision but are not subject to measurement in dollar terms.

4. Contrôle Interne Avancé-HEC Lausanne-2007/2008 4 Example 1: Differential Costs The following costs relate to a customer’s order of 100 printed shirts. Identify the differential costs. Variable costs: Shirts.....................$400 Printing labor...............75 Fixed costs: Print screen................$ 95 Machine depreciation........50 Manager’s salary............ 90 Total...................$710

5. Contrôle Interne Avancé-HEC Lausanne-2007/2008 5 Variable costs: Fixed costs: Example 1: Differential Costs The print screen is a differential cost since a screen must be created for this order. The printing labor for the shirts is a differential cost since it is a future expense due to the order. The cost of the shirts is a differential cost since it would not be an expense if the job were not taken. Shirts..................... $400 Printing labor............... 75 Print screen................ 95

6. Contrôle Interne Avancé-HEC Lausanne-2007/2008 6 Variable costs: Shirts.....................$400 Printing labor...............75 Fixed costs: Print screen................ 95 Total differential costs.....$570 Example 1: Differential Costs Depreciation is the allocation of a past cost and therefore is not a differential cost. A salary is not a differential cost because the salary will be paid regardless of the specific order.

7. Contrôle Interne Avancé-HEC Lausanne-2007/2008 7 Example 2: Differential Costs Mike bought a machine two years ago for $2,000. If he buys a new machine for $3,000, he can sell the old machine for $500. The electricity cost for both machines is $0.30 per hour. The old machine requires maintenance costs of $500 a year, while the new machine will only incur costs of $200 per year. What are the differential costs? Differential costs: $3,000 – cost of new machine $500 – salvage value of old machine $300 – difference in maintenance costs

8. Contrôle Interne Avancé-HEC Lausanne-2007/2008 8 Example 3: Total Costs A machine, used in production, has been owned and used for seven years. The machine only has two more years before the company disposes of it and its useful life ends. It runs okay, yet the company could use a newer, more productive machine. Should the machine be used for two more years, or should the company purchase a new machine? Note: When using the total-cost approach, we must look at all costs.
