Incorporating Risk into Capital Budgeting
Two Methods:• Certainty Equivalent Approach• Risk-Adjusted Discount Rate

How can we adjust this model to take risk into account?
• Adjust the After-tax Cash Flows (ACFs), or• Adjust the discount rate (k).
NPV = - IO ACFt(1 + k) t
n
t=1

Certainty Equivalent Approach
• Adjusts the risky after-tax cash flows to certain cash flows.• The idea:

Certainty Equivalent Approach
• Adjusts the risky after-tax cash flows to certain cash flows.• The idea:
Risky Certainty CertainCash X Equivalent = CashFlow Factor (a) Flow
![Page 12: Chapter 11: Capital Budgeting and Risk Analysis](https://reader035.fdocuments.in/reader035/viewer/2022081415/5681615f550346895dd0ea3e/html5/thumbnails/12.jpg)
Certainty Equivalent Approach
Risky Certainty CertainCash X Equivalent = CashFlow Factor (a) Flow
Risky “safe”$1000 .70 $700

Certainty Equivalent Approach
Risky Certainty CertainCash X Equivalent = CashFlow Factor (a) Flow
Risky “safe”$1000 .95 $950

• The greater the risk associated with a particular cash flow, the smaller the CE factor.

Certainty Equivalent Approach
• Steps:1) Adjust all after-tax cash flows by
certainty equivalent factors to get certain cash flows.
2) Discount the certain cash flows by the risk-free rate of interest.

Incorporating Risk into Capital Budgeting

Risk-Adjusted Discount Rate
• Simply adjust the discount rate (k) to reflect higher risk.• Riskier projects will use higher risk-
adjusted discount rates.• Calculate NPV using the new risk-
adjusted discount rate.

Risk-Adjusted Discount Rates
• How do we determine the appropriate risk-adjusted discount rate (k*) to use?• Many firms set up risk classes to
categorize different types of projects.

Summary: Risk and Capital Budgeting
You can adjust your capital budgeting methods for projects having different levels of risk by:
• Adjusting the discount rate used (risk-adjusted discount rate method),
• Measuring the project’s systematic risk,• Computer simulation methods,• Scenario analysis,• Sensitivity analysis.
