WACC vs CAPM Criteria

As a recent MBA graduate, you are involved in the project analysis of your company that has three divisions in different business sectors. Your company’s current practice for project analysis is to apply its weighted average cost of capital (WACC) of 12% as a single hurdle rate to all projects across all three divisions.

(a) Criticize your company’s current practice of project evaluation; (b) Discuss the long-term consequences of following this practice including with respect to the riskiness of projects to be accepted and rejected; and (c) What alternative PRACTICAL criteria and approach(es) to measure them would you suggest to your boss for project evaluation? (Hints: Refer to my lecture video and class notes in Session IV.)

Instructions:

Please post your initial response by 23:59 EST Day 4 of the Week, and comments on the posts of at least four classmates by 23:59 EST Due Date.

Each Discussion Topic carries 10 points (6 points for own answers and 4 points for responses to classmates’ posts). You must first post your own answers directly to the DT by Day 4 of the Week before accessing other students’ answers. In addition, youshould post at least FOUR thoughtful and substantive responses to other classmates’ answers/comments by the due date in order to earn full 10 points for each DT. A mere “Yes, I agree” or “No, I don’t agree” type of responses will not be given any credit.

Additional bonus credit may be given to at least TWO additional substantive responses to classmates’ posts at DIFFERENT DATES as they are valued and enrich our online learning.

Concluding comments on each Discussion Topic will be posted on the Discussion folder after due date.

Therefore, investors will not pay a premium to avoid diversifiable, unsystematic risk, or will not require a premium to accept this risk. The only relevant risk for an asset is non-diversifiable, systematic risk. How to measure this risk -----> BETA
5.
Concepts of Beta
(1) “Beta” measures the sensitivity of a security’s return to general market
movements (or to the return on market portfolio).
𝑘̃𝑖 = 𝛼 + 𝛽𝑖 𝑘̃𝑚 + 𝜀̃𝑖
𝜎𝑖 2 = 𝛽 𝑖 2 𝜎 2 (𝑘𝑚 ) + 𝜎 2 (𝑘𝑖 )

(2) Beta is the slope of a Characteristic line (CL) which relates individual
asset’s returns to market returns.

Question: What is the BETA of a portfolio investing ½ in Treasury-bill
and ½ in S&P 500 stock index?

For a given level of BETA, what rate of return will investors
require on a stock in order to compensate for their risk?

Capital Asset Pricing Model (CAPM): Security Market Line (SML)

Notes:
1.
Slope of SML = (km – kf) = market risk premium
2.

Hence, a stock’s BETA depends upon
i)
its correlation with market return as a whole
ii)
its own variability
iii) market variability
Example)
XYZ Company Stock Beta = 0.4; kf = 9%; km = 13%.
What should the required return for XYZ Company stock be?
=> kXYZ = 9% + (13% – 9%) * 0.4 = 10.6%
88
Example) Computing beta and understanding concept of the CAPM
The market portfolio has a standard deviation of 20%, and the covariance between the
returns on the market and those on stock Z is 800 (%2).
(a) What is the beta of stock Z?

For a fully diversified portfolio, unsystematic risk is close to zero. Therefore,
p2 ≈ ßp2m2
p ≈ ßpm = 2 x (20%) = 40%
(c) If the market portfolio gave an extra return of 5%, how much extra return can you
expect from stock Z?
Market risk premium = E(km) – kf = 5%
Hence, risk premium for stock z
= ßz x Market risk premium
= 2.0 x 5% = 10%

Words of Caution When Using the CAPM

The CAPM is an ex ante model, but we use expost-data to measure it.

No adjustment for future expectations

SML can shift over time due to changes in the risk-free rate of return

BETAs can change over time

Anomalies (inefficiencies) observed empirically
i)
Small capitalization stocks
ii)
Low P/E stocks
iii)
Seasonal effects

APPLICATIONS OF THE CAPM TO CAPITAL BUDGETING
 In equilibrium, all securities and assets should lie on the SML. Thus, E(ki) from the
CAPM represents the minimum required rate of return or Risk-Adjusted Discount
Rate (RADR) for the asset given its level of risk.
Example)
Stock A’s beta = 0.4; kf = 9%; rm = 13%;
E(kA) = kA = 9% + (13% – 9%) x 0.4 = 10.6% 0, accept the project.

where k (RADR) is measured from the CAPM.

 For asset A:

 For asset B:

 In disequilibrium, the asset is either overpriced (return too low) or underpriced
(return too high). Investors will bid up (down) underpriced (overpriced) assets.
93
Application of the CAPM to Capital Budgeting (or Project Evaluation)
Step 1:
Estimate the project’s beta
Step 2:
Use the CAPM to measure the project’s risk-adjusted discount rate
(RADR) or the project’s required rate of return or cost of capital.
Step 3:
Compare the project’s RADR with its expected return (or IRR).
If expected return > RADR => ACCPET the project. (Lies above SML)
If expected return < RADR => REJECT the project. (Lies below SML)

kUSR = 5.5% + (5.0%) x 0.88 = 9.90%

Questions: Should Project B be accepted? / Should Project C be rejected?
If a company’s WACC is being used as a criterion in investment decision, it would
accept/reject a project regardless of the project’s risk (BETA) as long as the project
offers a higher return than the company’s WACC.
This may lead to rejecting many good low-risk projects (such as C) and to accepting
many poor high-risk projects (such as B). Because each project may have a risk
different from the company’s overall asset, the company’s WACC cannot be employed
as an across-the-board cutoff rate.
In sum, the company’s WACC is the correct cutoff rate for projects that have the
same risk as the company’s existing business, but it is not for projects that are safer or
riskier than the company’s average risk.
Divisional Cost of Capital

across-the-board expansion: use the company’s stock beta

expansion into other industry: use the beta of a similar firm in other industry

Also holds true for subsidiaries of a holding company  use the BETA of a
similar, independent company operating in the same industry.

Example : Old AT&T
– New project in telephone industry: can use its own beta of 0.50
– New project in PC industry: should use a higher beta of 1.49
97
Example) Company Beta vs. Project Beta
A company is deciding whether to issue stock to raise money for an investment
project which has the same risk as the market and an expected return of 20%. If the
risk-free rate is 10% and the expected return on the market is 15%, the company
should go ahead
(a) Unless the company’s beta is greater than 2.0.
(b) Unless the company’s beta is less than 2.0.
(c) Whatever the company’s beta.
Which answer is correct? Say briefly why.
——————–Answer is _____.
βA = 1.0; E(kA) = 20%; kf = 10%; E(km) = 15%.
According to the CAPM,
kA = kf + (E(km) – kf) x βA = 10% + (15% – 10%) x 1.0 = 15%.
The project’s expected return is 20%, which is greater than its required rate of
return of 15%. Hence, the company should accept the project regardless of the
company’s beta. In this analysis, the company’s beta is irrelevant since the
investment project has a different risk (beta is equal to 1) than the company’s
average risk.
98
Practical Approach to Determining Cost of Capital
for a Project in a Division / Product Line
1.
Determine the company-wide cost of capital (weighted average cost of capital)
WACC = wd kd (1-T) + wps kps + ws ks
Where
kd = cost of debt
kps = cost of preferred stock
ks = cost of common stock
2.
Classify the company divisions / product lines into three to five groups of risk
level, and then adjust the company’s WACC accordingly to reflect the risk
level of each division / product line:
Add or Subtract
Division’s Risk Level

Average risk

Similarly, classify each division’s projects into three to five groups of risk

Example) Measuring WACC – Fisher Company
Cost of Debt: kd
Fisher Company is in the 34% marginal tax bracket. Its investment bankers estimate
that the firm would have to set a coupon rate of 12 percent on its new par bonds.
After-tax cost of debt = kd (1 – T) = 12% (0.66) = 7.9%
Cost of Preferred Stock: kps
The firm could sell preferred stock with a $10 annual dividend for $100, but would
incur $3 in flotation costs on each share sold.

Cost of Retained Earnings: ks
Fisher Company’s common stock is expected to pay a dividend over the next year of
$5.00, and it sells for $50.00. The firm has an expected constant growth rate of 5

percent. Over the years, the company has paid an average risk premium of 3% for its

CAPM Approach:
ks = kf + (km – kf) x BETA = 7% + (5%)1.6 = 15.0%
(c)
Bond Yield Plus Risk Premium Approach:
ks = Bond rate + risk premium = 12% + 3% = 15.0%.
