Cash Flow Estimation and Risk Analysis
Learning Objectives
After reading this chapter, students should be able to:
◆ Identify “relevant” cash flows that should and should not be included in a capital budgeting analysis.
◆ Estimate a project’s relevant cash flows and put them into a time line format that can be used to
calculate a project’s NPV, IRR, and other capital budgeting metrics.

12-4 Cash outflow = $40,000.
Increase in annual after-tax cash flows: CF = $9,000.
12-5 First, solve for each project’s NPV.
Project A: CF0 = -20000, CF1 = 6000, Nj = 6, I/YR = 10; solve for NPV = $6,131.56.
12-6 a. The applicable depreciation values are as follows for the two scenarios:
Scenario 1 Scenario 2
Year (Straight-Line) (MACRS)
1 $200,000 $264,000
b. To find the difference in net present values under these two methods, we must determine the
difference in incremental cash flows each method provides. The depreciation expenses cannot
simply be subtracted from each other, as there are tax ramifications due to depreciation

Coefficient of variation:
b. Project B is the riskier project because it has the greater variability in its probable cash flows,
whether measured by the standard deviation or the coefficient of variation. Hence, Project B is
evaluated at the 12% cost of capital, while Project A requires only a 10% cost of capital.

and then solve for NPVB = $2,679.46.
Since neither project can be repeated, Project B should be selected because it has a higher NPV
than Project A.
