Inca, Inc. Case 21
Capital Budgeting with Risk
Purpose: The student goes through the statistical procedure of determining risk for investments. Though
one investment alternative provides the higher net present value, is also has a much higher coefficient of
variation and the student must take this into consideration in describing his or her results. The case is
then expanded into six alternatives for which the student is asked to select the lowest risk option.
Relation to Text: This case should follow Chapter 13.
Complexity: This case is straightforward and should require 30-45 minutes to solve.

6. Based on the coefficient of variation, the standard size restaurant is much less risky (.722 versus
1.141).
Earlier in question two, the preference was clearly for expanded size restaurants. The general
principle is that you may not wish to always go with the highest return. Risk must be considered as
well.
7. Coefficient of variation
4 standard, 1 expanded $ 641,630 / 753,760     = .851
3 standard, 2 expanded 832,460 / 875,420   = .951
2 standard, 3 expanded 1,025,800 / 997,280   = 1.028
1 standard, 4 expanded 1,220,400 / 1,119,040 = 1.091
Based on the answer to question five as well as this question, the lowest-risk alternative is still the
five standard restaurants with a coefficient of variation of .722.
