B 0.9 0.25
C 0.95 0.35
D 1 0.3
The asset betas for the pure plays are:
Firm Aβ
A 0.77
B 0.675
C 0.6175
D 0.7
Average βA = 0.7.
This is taken as proxy asset beta of the project.
Now, levered beta for the project = βE = βA/(E/V)
= 0.70/0.7 = 1.0
If
Rf= 11 percent
(RM – Rf) = 10 percent
Cost of equity for the project = Rf + βL [E (RM) – Rf]
= 11 + 1.0[10 percent]
= 21 percent

The project’s debt to value ratio is to be used in WACC calculation.
Certainty Equivalent
Under the Certainty Equivalent method, the risky cash flows are adjusted downwards by a risk adjustment
factor and converted into a series of certain cash flows. The series is to be discounted using a risk free rate.
The higher the uncertainty regarding the realization of the cash flow, the lower is its value today, that is, the
lower the certainty equivalent:
