3Purpose of the WACC
- The weighted average cost of capital tells the
financial manager the minimum rate of return that
investors in the firm require as compensation for
their investment. - It is the relevant discount rate that should be
used when evaluating capital budget proposals (as
long as those proposals have the same basis risk
as the firm as a whole.) - It can be used to evaluate the performance of
management through measures such as economic
value added (EVA) - It can provide an appropriate foundation for
compensation incentives for managers and
employees that take the interests of shareholders
into account.
4Calculating WACC(The issue of current
liabilities.)
- General Guidelines
- we generally measure the cost of the major
long-term sources of financing that represent the
CORE financing sources for the firm. - this means that we generally exclude from this
the cost of any current liabilities (accruals and
notes payable), because while large firms may
utilize these sources, they are usually a
temporary (or impermanent) source of financing
and in relative terms, the dollar amount of
current liabilities is often immaterial given the
amount of long-term debt and equity financing
used. - another problem with current liabilities is that
they often dont have an explicit cost that can
be objectively measured. (ie. employees dont
charge interest on wages they have earned, but
that not yet been paid.)
5Calculating WACC(The formula)
Once you have the specific marginal costs of
capital (after accounting for taxes and
floatation costs) and you have found the
appropriate weights to use, the actual
calculation of a WACC is a simple matter.

spreadsheet)
Use of a spreadsheet model to calculate the WACC
can be helpful
7Weighting Systems(Three systems to choose from.)
- There are three different weighting systems
- book value weights least desirable
- market value weights
- target (optimal) capital structure weights. best
- If you have optimal weightsuse themthey are
superior to the other systems. - If you dont have optimal weights, but can
calculate market value weightsuse them. - If nothing else is available, use book value
weights.
8Book Value Weights
- These weights come from the firms most recent
balance sheet. - Since the balance sheet is based on historical
costs, it may not be reflective of current market
values, nor is it likely to reflect the firms
target capital structure objective. - This weighting system should only be used in
situations where optimal and market value weights
either are not available or cannot be determined
from the information given.

10Market Value Weights
- In order to calculate market value (MV) weights,
you will need to know the total market value of
debt, and common stock (and preferred stock if
the company uses it.) - To calculate total MV you need to know the
current price of the security in each class, as
well as the total number of securities
outstanding - Total Market Capitalization Price times
Quantity - The following balance sheet date, when combined
with market price data, will allow you to
calculate MV weights.

13Market Value Weights
- As you can see, MV weights can differ
substantially from book value weights this is
because MV weights reflect current prices (hence
they reflect current interest rates and other
economic factors including the going concern
value of the stock). - BV weights reflect history.
14Optimal Capital Structure Weights
- Optimal or target capital structure weights are
the relative weights of debt, preferred and
equity that will result in maximization for the
firms value and concurrently, minimization of
the firms WACC. - At this stage in the course they will often be
given to you. - As you will learn in the capital structure
portion of the course, the optimal capital
structure occurs because of the tax-deductibility
of interest expense the firm incurs on debt
financing. - As the firm uses more and more debt, however, the
benefits of the lower cost of debt is eventually
offset by the present value of bankruptcy costs. - At some intermediate use of debt, these forces
offset one another producing a point where the
value of the firm is maximized.

16Specific Marginal Cost of Equity
- There are a number of different approaches that
can be used to estimate the cost of equity.
Certainly the two most common (since they are
based on current market conditions) are - Dividend Capitalization Model Approach, and
- the Capital Asset Pricing Model Approach.
- You will want to determine the investors
required return (ie. calculate the cost of
retained earnings) and then, calculate the cost
of new equity (taking floatation costs into
account).
17Specific Marginal Cost of Equity
- Dividend Capitalization Model Approach
- the current stock price and most recent dividend
of a publicly traded firm should be readily
available. The only thing you will need to
estimate is the growth rate.
18Specific Marginal Cost of Equity
- Estimating the growth rate for dividends
- one way to do that is to calculate the percentage
change in dividends per share, each year for the
past few years, and then to average those
percentage returns. - Or, you can determine the compound growth in
dividends by taking the last DPS and equating it
with an earlier DPS and solving for the compound
rate in the following equation - Or, you can estimate next years growth rate
based on current earnings plus the rate of return
earned on earnings that were retained by the firm
this year.
19Specific Marginal Cost of Equity
- Estimating the growth rate for dividends
- CAUTION
- Dont forget that the constant growth dividend
capitalization model uses one growth rateand it
is assumed by the model, that that growth will
start now and will continue on forever! - If this assumption is not suitable given what
you know about the company and its stock, then,
use of a different model or approach will be
required.
20Specific Marginal Cost of Equity
- Capital Asset Pricing Model Approach
- the risk-free rate (yield on 91-day T-bills) is
readily observable. The expected return on the
market portfolio and the beta risk of the company
will have to be estimated by you based on your
research in the marketplace.
21Specific Marginal Cost of Preferred Stock
- Preference shares usually take the form of
another Class of shares. This class usually has
a priority of claims that is superior to that of
the common share class, and usually has a fixed
or stated dollar dividend per share. For
example, Class B 2.50 shares. - The dividend, despite being stated, is NOT a
legal obligation of the firmhowever, management
will do everything it can to pay those dividends
annually, since most preferred shares also
carry a cumulative feature. - Because of this, we can use the no-growth
dividend capitalization model to value the
preference shares. If we have the current
market price of those shares (23.32) and the
DPS, we can estimate the preferred shareholders
required rate of return from this market data
22Specific Marginal Cost of Preferred Stock
- Floatation costs associated with preferred stock
may be 6. If this is the case we can determine
the cost of new preferred stock by incorporating
this into the required rate of return formula
23Specific Marginal Cost of Debt
- The cost of debt to a taxable corporation is a
function of - the debt investors required return,
- the floatation cost percentage that will be borne
by the firm to raise new debt capital externally,
and - the income tax rate facing the firm (because
interest expense is tax deductible). - To determine the cost of debt follow these steps
- 1. Calculate the investors required return on
debt (ie. calculate the YTM on the companys
current bonds) - 2. Multiply the investors required return by (1
- t) where tcorporate tax rate - 3. Divide the after-tax required return by (1- f)
where f floatation cost percentage.
24Specific Marginal Cost of Debt
- There are two different approaches used to
calculate the investors required return - The approximation approach
- The exact approach to determining the Yield to
Maturity - - solve for the discount rate that equates the
current market price of the bonds with the sum of
the present value of all cash flows expected from
this investment.
25Specific Marginal Cost of Debt
- The exact approach to determining the Yield to
Maturity - - solve for the discount rate that equates the
current market price of the bonds with the sum of
the present value of all cash flows expected from
this investment.

27Specific Marginal Cost of Debt
- NOTE
- It is very important for you to realize that even
though investors in a companys bonds currently
require, lets say a 12 return, a new issue of
bonds by the same firm COULD require a different
rate of return. - This is because each bond issue will have
different assets pledged as collateral for the
loanand the default risk to which the investor
is exposed, is a function of the likely
liquidation value of those specific assets (some
equipment might be sold at 0.40 on the dollar,
while a functioning plant and equipment might get
0.80 on the dollar). - Further, it is unlikely that the new bond issue
will have a superior claim to the current
bondholders because of other restrictive
covenants. - BOTTOM LINE the actual required rate of return
on a new issue will no doubt be higher than the
current required rate of return investors demand
on the outstanding bonds of the firm.
28Investment Opportunity Schedule (IOS)
- In any one year, a firm may consider a number of
capital projects. - The greater the number of projects undertaken,
the more money that the firm will have to raise
in order to finance them. - There is a limit to the amount of money that can
be raised in any one year (ie. the capital
markets are finite ie. there is a limit to the
number of investors and their investment dollars
that will consider investing in any prospect in
any given year.) hence it is important that the
capital budgeting analysis be extended to take
this fact into account.
29Investment Opportunity Schedule (IOS)
- This Investment opportunity schedule is the
prioritized list of capital projects, listed by
IRR (internal rate of return) from highest to
lowest. - At the same time, the cumulative investment
required is listed. - Example
- Consider a firm that has six different capital
investment proposals this year. Each project has
its own IRR and capital cost. - (see the next slide)
30Investment Opportunity Schedule (IOS)
- Example
- Consider a firm that has six different capital
investment proposals this year. Each project has
its own IRR and capital cost. Each project has
the same risk as the firm as a whole.
31Investment Opportunity Schedule (IOS) ...
- Example
- The first step in developing an IOS is to order
the projects from highest IRR to lowest, and then
to calculate the cumulative capital cost of the
projects.
32Investment Opportunity Schedule (IOS) ...
- Example
- First, it is clear that project A is
unacceptableit offers a rate of return (IRR)
that is less than the firms cost of capital. - The remaining projects certainly meet the first
investment screen (they have positive NPVs
that is, they offer rates of return in excess of
the firms WACC). - Now we can prepare a graphical representation of
the IOS by plotting the projects IRR against the
cumulative dollars of capital to be raised.

38Calculating the break in the MCC
- The preceding diagram illustrates how marginal
projects can be rejected because of the
increasing marginal cost of capital. - The most common reason for the MCC to rise, is
because the firm will often use retained
earnings, before it will go outside the firm to
raise external equity. (This makes a lot of
sense since new equity means incurring floatation
costs.) -
- Breaks can also occur because the firm has to
issue a different bond issue or preferred issue
at a higher required return. - If a firms optimal capital structure is 46
equity, 11 preferred stock and 43 debt, and it
has 2,576,000 of retained earnings to use for
capital investment the break in the MCC (the
point where R/E will be exhausted will occur at
(2,576,000 / .46 5,600,000) of capital to be
raised.
39WACC before and after the break in the
MCC(Modeling the solution on a spreadsheet)
The cost of capital before the break assumes use
of retained earnings (ie. the cost of equity
without (5) floatation costs (and the WACC after
the break assumes the cost of external equity)
40 Understanding Breaks in the MCC
41NPV Profiles(Varying the discount rate and
finding the range of possible NPVs.)
- The WACC is an estimateand as an estimate it can
be wrong (perhaps as much as 1 to 2) - Consequently, once we have our estimate, it is
sometimes useful to test the NPV of our capital
project against varying discount rates to see
over what range of discount rates the NPV will
remain positive. - This can be done on a spreadsheet, and then
graphed for greater visual clarity. (Shown in
the following two slides.)
42NPV Profiles(Varying the discount rate and
finding the range of possible NPVs.)
43NPV Profiles(Varying the discount rate and
finding the range of possible NPVs.)
IRR 16
If the firms cost of capital is 16 or less,
then adoption of the project will increase the
value of the firm. If there is any uncertainty
that the WACC could be higher than 16, further
attention would be required.
44Divisional Costs of Capital
- An overall cost of capital developed for a highly
diversified conglomerate may not be appropriate
for decisions made within specific divisions of
the company. - High-risk divisions (with high return
possibilities) would have a disproportionate
share of their investment proposals accepted if
they use an overall WACC. - The solution to this is to develop risk-adjusted
discount rates that reflect the unique risk
characteristics of each division. - Developing these estimates can sometimes be
accomplished by looking at other firms in that
industry that are not highly diversified in their
operations this is called the pure play approach.
