Corporate Finance: Bigger Picture
These decisions are highly inter-related
Suppose a firm wishes to invest in a new project…
The project needs financing…
This can be paid with retained earnings (cash), by borrowing more (debt) or by a share issue (equity)
Cash: the investment decision affects the Dividend decision
Debt/Equity: the investment decision affects the Financial decision

Maximizing shareholders wealth
Maximizing firm’s value
Maximizing share price
The strength of the stock price maximization objective function is its internal self correction mechanism.
Choose an Objective Function
Maximizing Shareholders’ Value
Firms can always focus on a different objective function. Examples would include maximizing revenues maximizing firm size maximizing market share …
The key thing to remember is that these are intermediate objective functions. To the degree that they are correlated with the long term
health and value of the company, they work well. To the degree that they do not, the firm can end up with a
disaster

Maximizing Shareholders’ Value
Goal of the firm
Goal of the firm
In theory: The stockholders have significant control over management.
The two mechanisms for disciplining management are (a) the annual meeting and (b) the board of directors. Specifically, we assume that Stockholders who are dissatisfied with managers can not only express
their disapproval at the annual meeting, but can use their voting power at the meeting to keep managers in check.
The board of directors plays its true role of representing stockholders and acting as a check on management.
In Practice: Neither mechanism is as effective in disciplining management.
Maximizing Shareholders’ Value
I. Managers and Shareholders
Goal of the firm
The power of stockholders to act at annual meetings is diluted: Most small stockholders do not go to meetings because the cost of going
to the meeting exceeds the value of their holdings. For large stockholders, the path of least resistance, when confronted by
managers that they do not like, is to vote with their feet (buy other company stocks).
Annual meetings are also tightly scripted and controlled events, making it difficult for outsiders and rebels to bring up issues that are not to the management’s liking.
Maximizing Shareholders’ Value
I. Managers and Shareholders
In 2010, the median board member at a Fortune 500 company was paid $212,512, with 54% coming in stock and the remaining 46% in cash. If a board member is a non-executive chair, he or she receives about $150,000 more in compensation.
A board member works, on average, about 227.5 hours a year (and that is being generous), or 4.4 hours a week, according to the National Associate of Corporate Directors. Of this, about 24 hours a year are for board meetings.
Many directors serve on three or more boards, and some are full time chief executives of other companies.
Goal of the firm
Board of Directors as a disciplinary mechanism
Maximizing Shareholders’ Value
I. Managers and Shareholders
A 1992 survey by Korn/Ferry revealed that 74% of companies relied on recommendations from the CEO to come up with new directors; Only 16% used an outside search firm. While that number has changed in recent years, CEOs still determine who sits on their boards. While more companies have outsiders involved in picking directors now, CEOs still exercise significant influence over the process.
Directors often hold only token stakes in their companies. The Korn/Ferry survey found that 5% of all directors in 1992 owned less than five shares in their firms. Most directors in companies today still receive more compensation as directors than they gain from their stockholdings. While share ownership is up among directors today, they usually get these shares from the firm (rather than buy them).
Many directors are themselves CEOs of other firms. Worse still, there are cases where CEOs sit on each other’s boards.

I. Managers and Shareholders
The CEO often hand-picks directors
Board of Directors as a disciplinary mechanism
Calpers, the California Employees Pension fund, suggested three tests in 1997 of an independent board
Are a majority of the directors outside directors?
Is the chairman of the board independent of the company (and not the CEO of the company)?
Are the compensation and audit committees composed entirely of outsiders?
Disney (1997) was the only S&P 500 company to fail all three tests.

Goal of the firm
Maximizing Shareholders’ Value
In theory: there is no conflict of interests between stockholders and bondholders.
In practice: Stockholder and bondholders have different objectives. Bondholders are concerned most about safety and ensuring that they
get paid their claims.
Stockholders are more likely to think about upside potential
II. Shareholders’ objectives vs. Bondholders’ objectives
Goal of the firm
Maximizing Shareholders’ Value
Examples of the conflict…
Increasing dividends significantly: When firms pay cash out as dividends, lenders to the firm are hurt and stockholders
may be helped. This is because the firm becomes riskier without the cash.
Taking riskier projects than those agreed to at the outset: Lenders base interest rates on their perceptions of how risky a firm’s investments are.
If stockholders then take on riskier investments, lenders will be hurt.
Borrowing more on the same assets: If lenders do not protect themselves, a firm can borrow more money and make all
existing lenders worse off.

II. Shareholders’ objectives vs. Bondholders’ objectives
Goal of the firm

In theory: Financial markets are efficient. Managers convey information honestly and in a timely manner to financial markets, and financial markets make reasoned judgments of the effects of this information on 'true value'. As a consequence-
A company that invests in good long term projects will be rewarded.
Short term accounting gimmicks will not lead to increases in market value.
Stock price performance is a good measure of company performance.
In practice: There are some holes in the 'Efficient Markets' assumption.
III. Firms and Financial Markets
Goal of the firm
Maximizing Shareholders’ Value
Managers control the release of information to the general public
Information (especially negative) is sometimes suppressed or delayed by managers seeking a better time to release it.
In some cases, firms release intentionally misleading information about their current conditions and future prospects to financial markets.
III. Firms and Financial Markets
Goal of the firm
Maximizing Shareholders’ Value
Evidence that managers delay bad news?
III. Firms and Financial Markets
Goal of the firm
Maximizing Shareholders’ Value
Some critiques of market efficiency...
Investors are irrational and prices often move for no reason at all. As a consequence, prices are much more volatile than justified by the underlying fundamentals. Earnings and dividends are much less volatile than stock prices.
Investors overreact to news, both good and bad.
Financial markets are manipulated by insiders; Prices do not have any relationship to value.
Investors are short-sighted, and do not consider the long-term implications of actions taken by the firm
III. Firms and Financial Markets
Goal of the firm
Maximizing Shareholders’ Value
In theory: All costs and benefits associated with a firm’s decisions can be traced back to the firm.
In practice: Financial decisions can create social costs and benefits. A social cost or benefit is a cost or benefit that accrues to society
as a whole and not to the firm making the decision. Environmental costs (pollution, health costs, etc..)Quality of Life' costs (traffic, housing, safety, etc.)
Examples of social benefits include:creating employment in areas with high unemploymentsupporting development in inner cities creating access to goods in areas where such access does not
exist
IV. Firms and the Society
Goal of the firm
Maximizing Shareholders’ Value
Social Costs and Benefits are difficult to quantify because ...
They might not be known at the time of the decision. In other words, a firm may think that it is delivering a product that enhances society, at the time it delivers the product but discover afterwards that there are very large costs.
(Asbestos was a wonderful product, when it was devised, light and easy to work with… It is only after decades that the health consequences came to light)
They are ‘person-specific’, since different decision makers can look at the same social cost and weight them very differently.
They can be paralyzing if carried to extremes.
IV. Firms and the Society
Goal of the firm
Maximizing Shareholders’ Value
A test of your social consciousness: Put your money where you mouth is…
Assume that you work for Disney and that you have an opportunity to open a store in an inner-city neighborhood. The store is expected to lose about a million dollars a year, but it will create much-needed employment in the area, and may help revitalize it.
Would you open the store?
Yes
No
If yes, would you tell your stockholders and let them vote on the issue?
Yes
No
If no, how would you respond to a stockholder query on why you were not living up to your social responsibilities?

Conclusions
In the context of our discussion:
managers taking advantage of stockholders has led to a much more active market for corporate control.
stockholders taking advantage of bondholders has led to bondholders protecting themselves at the time of the issue.
firms revealing incorrect or delayed information to markets has led to markets becoming more “skeptical” and “punitive”
firms creating social costs has led to more regulations, as well as investor and customer backlashes.

Time Value of Money
Present Value Calculations
Reasons why a cash flow in the future is worth less than a
similar cash flow today:
Individuals prefer present consumption to future consumption.
People would have to be offered more in the future to give up present
consumption.
When there is monetary inflation, the value of currency decreases
over time. The greater the inflation, the greater the difference in value between a cash flow today
and the same cash flow in the future.
Any uncertainty (risk) associated with the cash flow in the future
reduces the value of the cashflow.A promised cash flow might not be delivered for a number of reasons: the promisor might
default on the payment, the promisee might not be around to receive payment; or some
other contingency might intervene to prevent the promised payment or to reduce it.
Present Value Calculations
Time Value of Money
The process by which future cash flows are
adjusted to reflect these factors is called
discounting,
and the magnitude of these factors is
reflected in the discount rate.

Present Value Calculations
A simple cash flow is a single cash flow in a specified
future time period; it can be depicted on a time line:
where CFt= the cash flow at time t.
This cash flow can be discounted back to the present using a discount rate
that reflects the uncertainty of the cash flow.
Concurrently, cash flows in the present can be compounded to arrive at an
expected future cash flow.

Example: Valuing a Console Bond
A console bond is a bond that has no maturity and pays a fixed
coupon. Assume that you have a 6% coupon console bond.
The value of this bond, if the interest rate is 9%, is as
follows:
Value of Console Bond = $60 / .09 = $667
The value of a console bond will be equal to its face value
(which is usually $1000) only if the coupon rate is equal to
the interest rate.
Present Value Calculations

A growing perpetuity is a cash flow that is expected to grow
at a constant rate forever.
The present value of a growing perpetuity can be written as:
𝑃𝑉 𝑜𝑓 𝐺𝑟𝑜𝑤𝑖𝑛𝑔 𝑃𝑒𝑟𝑝𝑒𝑡𝑢𝑖𝑡𝑦 =𝐶𝐹1
𝑟−𝑔
where CF1 is the expected cash flow next year, g is the constant growth rate
and r is the discount rate.
The fact that a growing perpetuity lasts forever puts constraints on
the growth rate. It has to be less than the discount rate for this
formula to work.
Present Value Calculations
Present ValueGrowing Perpetuity
Example: Valuing a Stock with Stable Growth in Dividends
In 1992, Southwestern Bell paid dividends per share of $2.73. Its earnings and dividends had
grown at 6% a year between 1988 and 1992 and were expected to grow at the same rate in the
long term. The rate of return required by investors on stocks of equivalent risk was 12.23%.
Current Dividends per share = $2.73
Expected Growth Rate in Earnings and Dividends = 6%
Discount Rate = 12.23%
Value of Stock = $2.73 *1.06 / (.1223 -.06) = $46.45
As an interesting aside, the stock was actually trading at $70 per share. This price could be
justified by using a higher growth rate. The value of the stock is graphed in figure 3.7 as a function
of the expected growth rate.
The growth rate would have to be approximately 8% to justify a price of $70.
This growth rate is often referred to as an implied growth rate.

An annuity is a constant cash flow that occurs at
regular intervals for a fixed period of time.
Defining A to be the annuity, the time line for an
annuity may be drawn as follows:
An annuity can occur at the end of each period, as in
this time line, or at the beginning of each period.

The present value of an annuity can be calculated by taking
each cash flow and discounting it back to the present and
then adding up the present values.
Alternatively, a formula can be used in the calculation. In
the case of annuities that occur at the end of each period,
this formula can be written as:
𝑃𝑉 𝑜𝑓 𝑎𝑛 𝐴𝑛𝑛𝑢𝑖𝑡𝑦 = 𝑃𝑉 𝐴, 𝑟, 𝑛 =𝐴

where
A = Annuity

Example: Estimating the Present Value of Annuities
Assume that you are the owner of Compnay X, and that you have a
choice of buying a copier for $10,000 cash down or paying $ 3,000
a year for 5 years for the same copier.
If the opportunity cost is 12%, which would you rather do?

The present value of the installment payments exceeds the cash-
down price; therefore, you would want to pay the $10,000 in cash
now.

Present Value Calculations
Alternatively, the present value could have been estimated
by discounting each of the cash flows back to the present
and aggregating the present values as illustrated below:

Present Value Calculations
Example : Present Value of Multiple Annuities
Suppose you are the pension fund consultant and that you are trying to estimate the present
value of the expected pension obligations, which amount in nominal terms to the following:
Years Annual Cash Flow
1 - 5 $ 200.0 million
6 - 10 $ 300.0 million
11 - 20 $ 400.0 million
If the discount rate is 10%, the present value of these three annuities can be estimated as
follows:
Present Value of 1st annuity = $ 200 million * PV (A, 10%, 5) = $ 758 million
Present Value of 2nd annuity = $ 300 million * PV (A,10%,5) / 1.105 = $ 706 million
Present Value of 3rd annuity = $ 400 million * PV (A,10%,10) / 1.1010 = $ 948 million
The present values of the second and third annuities can be estimated
in two steps:
First, the standard present value of the annuity is computed over the
period that the annuity is received.
Second, that present value is brought back to the present.
Thus, for the second annuity, the present value of $ 300 million each year for 5
years is computed to be $1,137 million; this present value is really as of the end
of the fifth year. It is discounted back 5 more years to arrive at today’s present
value which is $ 706 million.
Cumulated Present Value = $ 758 million+$706 million+$948 million = $2,412 million
Present ValueAnnuity
Present Value Calculations
In some cases, the present value of the cash flows is known and
the annuity needs to be estimated.
This is often the case with home and automobile loans, for
example, where the borrower receives the loan today and pays it
back in equal monthly installments over an extended period of
time.
This process of finding an annuity when the present value is
known is examined below

Example: Calculating The Monthly Payment On A House Loan
Suppose you are trying to borrow $200,000 to buy a house on a conventional 30-year mortgage
with monthly payments. The annual percentage rate on the loan is 8%. The monthly payments on
this loan can be estimated using the annuity due formula:
Monthly interest rate on loan = APR/ 12 = 0.08/12 = 0.0067
𝑀𝑜𝑛𝑡ℎ𝑙𝑦 𝑃𝑎𝑦𝑚𝑒𝑛𝑡 𝑜𝑛 𝑀𝑜𝑟𝑡𝑔𝑎𝑔𝑒 = $200,0000.0067
1 −1
1 + 0.0067 360
= $1473.11
This monthly payment is an increasing function of interest rates.
When interest rates drop, homeowners usually have a choice of refinancing, though
there is an up-front cost to doing so.
Present Value Calculations
Present ValueAnnuity
A growing annuity is a cash flow that grows at a constant rate for a
specified period of time.
If A is the current cash flow, and g is the expected growth rate,
the time line for a growing annuity appears as follows:
Note that, to qualify as a growing annuity, the growth rate in each period has
to be the same as the growth rate in the prior period.
Present Value Calculations

In most cases, the present value of a growing annuity can
be estimated by using the following formula:

The present value of a growing annuity can be estimated in all cases, but
one - where the growth rate is equal to the discount rate. In that case, the
present value is equal to the nominal sums of the annuities over the period,
without the growth effect:
PV of a Growing Annuity for n years (when r=g) = n A
Note also that this formulation works even when the growth rate is greater
than the discount rate.

Example: The Value Of A Gold Mine
Suppose you have the rights to a gold mine for the next 20 years, over which period you plan
to extract 5,000 ounces of gold every year. The current price per ounce is $300, but it is
expected to increase 3% a year. The appropriate discount rate is 10%. The present value of
the gold that will be extracted from this mine can be estimated as follows:
𝑃𝑉 𝑜𝑓 𝑒𝑥𝑡𝑟𝑎𝑐𝑡𝑒𝑑 𝑔𝑜𝑙𝑑 = $300 ∗ 5000 ∗(1 + 0.03)

The present value of the gold expected to be extracted from this mine is
$16.146 million; it is an increasing function of the expected growth rate in

Introduction
Shareholders invest in companies to make money.
Replacement projects (no need for very careful analysis)
Expansion projects, i.e. increasing the size of the firm (involves
more uncertainty)
New products or services (probably even riskier)
Regulatory, safety and environmental projects (often imposed by
regulatory agencies, so must be undertaken)
Pet projects (CEO getting a new aircraft!)
Capital Budgeting
IntroductionTypes of projects
Projects vary in level on analysis needed to take the decision
Independent projects
- undertaking one does not necessarily exclude the others
(provided that there is sufficient capital)
Mutually exclusive projects
- only one of the potential candidates may be undertaken
e.g. planning to buy a new machine, and there are two
which meet the requirements
In reality, company has a limited amount of capital to fund
potentially many recommended projects
→ Capital rationing
Capital Budgeting
IntroductionTypes of projects by compatibility
Managers undertake valuations to allocate capital (i.e. money
tied up in the form of equity / debt) between investment projects:
• Is Project A better than doing nothing?
• Is A better than B?
• Although A is better than B, should we still carry on B?
Appraisal methods help us in decision making. They take into
account:
• Cash flows – measure of value creation
• Time – opportunity cost of investing

Investment Appraisal MethodsPayback Period
How long does it take the project to “payback” its initial investment?
The payback rule says only accept projects that “payback” in the desired time frame.
A modified version that takes time value of money into account:
Discounted Payback Period = number of years required for the future cumulative discounted cash flows to match the initial outlay
Payback Period = number of years required for the future
cumulative cash flows to match the initial outlay
Capital Budgeting
Investment Appraisal MethodsPayback Period
Example
Payback Period = between 3 and 4 years Payback Period ~ 3.5 years Ranking criterion: Select the project with the lowest payback period
Year Cash flow ($) Cumulative cash flow ($)
0 (450) (450)
1 100 (350)
2 200 (150)
3 100 (50)
4 100 50
5 80 130
‘Zero’ (payback period) is
between 3&4 years
A conventional cash flow: A cash investment initially, followed by a series of cash inflows
over the life of a project
Advantages
Easy to understand, calculate, and communicate
In fact so straightforward that it is frequently used (but should really only be
used to get an initial indication)
Useful for companies that face cash flow constraints (e.g. small
companies) since it is biased toward liquidity
Arguably takes account of risk (since it assumes that a shorter
payback period is better than a longer one) – and assuming that
more distant cash flows are less certain (i.e. more risky)
Capital Budgeting
Investment Appraisal MethodsPayback Period
Disadvantages
Ignores cash flows after the payback period Income after the payback period is not considered, e.g. increasing the cash flow in
yr5 in our example must make the project better?
Biased against long-term projects
Ignores the time value of money Think back to our example: a cash flow of [£0, £0, £400] is considered equal to a
cash flow of [£400, £0, £0]
Arbitrary acceptance criterion (i.e. when there is a single project to consider) Why pick 3.5yrs over, say, 3yrs, or 4yrs?
Accepted projects may not actually add value to the company (or the shareholders’ wealth) All the Payback method really tells us is whether the company has the liquidity to
finance the project (although this can be important, particularly to small companies)
Capital Budgeting
Investment Appraisal MethodsPayback Period
Also known as return on investment (ROI) and accounting rate of return (ARR)
All definitions relate accounting profit to some measure of the capital employed
We will follow this formula:

𝐴𝑣𝑒𝑟𝑎𝑔𝑒 𝑖𝑛𝑣𝑒𝑠𝑡𝑚𝑒𝑛𝑡× 100
Accounting profits = before-tax operating cash flows adjusted to take account of depreciation
Average investment must take account of scrap value:
𝐴𝑣𝑒𝑟𝑎𝑔𝑒 𝑖𝑛𝑣𝑒𝑠𝑡𝑒𝑚𝑛𝑡 =𝐼𝑛𝑖𝑡𝑖𝑎𝑙 𝑖𝑛𝑣𝑒𝑠𝑡𝑒𝑚𝑛𝑡 + 𝑆𝑐𝑟𝑎𝑝 𝑣𝑎𝑙𝑢𝑒

Investment Appraisal MethodsReturn on Capital Employed (ROCE)
Project A generates annual cash flows (receipts less payments) of
$210,000 for 5 years
The initial cost of machinery is $500,000; no scrap value
Total cash profit = 210,000 × 5 = 1,050,000
Total accounting profit (after depreciation) = 550,000
Average accounting profit = 550,000/5 = 110,000
Average investment = (500,000 + 0)/2 = 250,000
ROCE =110 000
250 000= 44%
Ranking criterion: Select the project with the highest ROCE first

Return on Capital Employed (ROCE)Investment Appraisal Methods
Advantages
Percentage returns are familiar, and can be compared with the
ROCE of the company to determine if a new project is acceptable
Accounting information readily available
Reasonably simple to apply and can be used to compare mutually
exclusive projects
Unlike the payback method, ROCE considers all cash flows
Capital Budgeting
Return on Capital Employed (ROCE)Investment Appraisal Methods
Disadvantages
Accounting profits are not cash flows, since depreciation is an
accounting adjustment
Ignores time value of money
Arbitrary acceptance criterion: Compare ROCE to some ‘target’
rate of return
→ Is 44% ROCE high enough?
Accounting profits are not linked directly to maximising shareholder
wealth
Because average profits are used, the timing of profits is not taken
fully into consideration

Investment Appraisal MethodsNet Present Value (NPV)
NPV is based in solid theory
• It makes use of the time value of money
• And the PV concept we considered earlier in the module
NPV measures actual wealth creation because
• It uses cash flows
• It uses ALL cash flows during the project life
• It discounts ALL cash flows during the project life, using the
cost of capital (or the required rate of return)
Capital Budgeting
Investment Appraisal MethodsNet Present Value (NPV)
Can be done very easily in a spreadsheet using Excel
Notice that NPV has an inverse relationship with r
As r increases the NPV of a given project falls
This makes sense; the higher the rate of return we require the fewer projects
we would expect to be profitable
Capital Budgeting
Investment Appraisal MethodsNet Present Value (NPV)
Example
Capital Budgeting
Investment Appraisal MethodsNet Present Value (NPV)
NPV in EXCEL calculates PV
=NPV(0.1, C3:C6)C8
To estimate NPV we need to:
Estimate the initial cost
→ Usually this is known for certain
Estimate future cash flows
→ “Expected” future cash flows, so subject to errors
→ Risk of appraisal methods in general, not only NPV
Estimate discount rate
→ Required rate of return
→ CAPM

Suppose we know the two end points
[x0, y0],[x1,y1]
Substituting for y and x in the standard
formula for a straight line, y = ax+b, gives:
𝑎 =𝑦1 − 𝑦0
𝑥1 − 𝑥0
and 𝑏 = 𝑦0 −𝑦1−𝑦0
𝑥1−𝑥0𝑥0
Capital Budgeting
Investment Appraisal MethodsInternal Rate of Return (IRR)
This means the formula for a straight line becomes:
𝑦 =𝑦1 − 𝑦0
𝑥1 − 𝑥0𝑥 + 𝑦0 −
𝑦1 − 𝑦0
𝑥1 − 𝑥0𝑥0
Capital Budgeting
Investment Appraisal MethodsInternal Rate of Return (IRR)
To find the approximation of a true IRR, i.e. IRR*
is equivalent with solving the below for x:
𝑦 =𝑦1 − 𝑦0
𝑥1 − 𝑥0𝑥 + 𝑦0 −
𝑦1 − 𝑦0
𝑥1 − 𝑥0𝑥0
we obtain:
𝑥 = 𝑥0 − 𝑦0
𝑥1 − 𝑥0
𝑦1 − 𝑦0
which can be written in terms of points A and B as:

Since the relationship between NPV and
the discount rate of a conventional cash
flow is negatively sloped and convex the
estimate will always be an over-estimate
Generally, very computationally challenging, i.e. no formula, not
as straightforward as NPV
Trial & error – keep trying different discount rates untill NPV=0

Pitfall 3 - Mutually Exclusive ProjectsIRR sometimes ignores the magnitude of the project. The following two projects illustrate that problem.
Pitfall 4 - Term Structure AssumptionWe assume that discount rates are stable during the term of the project. This assumption implies that all funds are reinvested at the IRR. This is a false assumption. NPV allows for change in discount rate.
Capital Budgeting
Investment Appraisal MethodsInternal Rate of Return (IRR)
At 10% IRRA=19.5% while IRRB= 17%.
As the discount rate decreases, and before the lines cross, NPV suggests B, while IRR suggests A .
There is no conflict between these two methods when a singleproject with conventional cash flows is being considered
But for non-conventional (strange cash flows) mutually exclusive
projects, a conflict might arise
NPV is academically preferred because it measures the absolute
increase in value of the company
In all cases where there is no constraint on capital, the NPV
decision rule offers sound investment advice
Capital Budgeting
Investment Appraisal MethodsNPV vs. IRR
There are a number of issues that we need to take into account when applying NPV in practice (i.e. how do we come up with the cash flows and what considerations do we need to make?):
Relevant project cash flows – Ask whether a cash flow occurs as a result of undertaking a project (Incremental cash flows)
Taxation – what effect does taxation have on the cash flow from the project
Inflation – reduces the real value of future cash flows
Investment risk – when things don’t go as you expect
Capital Budgeting
Investment Appraisal ApplicationNPV vs. IRR
Capital Budgeting
Include:
• Cash in- and outflows resulting from the project, including
additional investment or working capital
• Opportunity costs / benefits foregone
• Side effects: Erosion or synergy
e.g. by launching Coke Zero, demand for Diet Coke will drop; by
launching iPhone, demand for Mac will increase
Ignore:
• Sunk costs(e.g. market research takes place whether the project goes ahead or not)
• Apportioned fixed costs – unless incremental / additional
• Any interest expenditure, even if debt financing
→ Adjustments for cost of debt reflected in r
Incremental Cash FlowsInvestment Appraisal Application
Opportunity Cost- Example
Project A requires 500 kg of material A
Suppose we have 1,000 kg of material A in inventory, which cost $2,000 when purchased 6 months ago
The supplier now quotes a price of $2.2 per kg, and the material can be resold at $1.9 per kg
What is the relevant cost of material A?
a) $1,000
b) $1,100
c) $950
(no, a sunk cost since the company has bought material A
already)
(yes, but only if the company has other projects that could
use material A)
(yes, but only if there is no other use for material A, which
would have to be resold if the project were not undertaken)
Capital Budgeting
Investment Appraisal ApplicationIncremental Cash Flows
Companies pay corporate tax
Estimate after-tax incremental cash flows for NPV
The amount and timing of tax payments affect NPV
Corporate tax is based on taxable profit which is not the same as
cash flow (see next slide)
For taxation purposes, capital expenditure is written off against
taxable profits by means of annual capital allowances
Capital Budgeting
Investment Appraisal ApplicationEffects of taxation
Timing of tax liabilities and benefits : UK
Tax liabilities taken as being paid one year after the originating
taxable profits
Tax benefits also received one year in arrears
Small UK companies (taxable profit < £1.5 m) pay tax nine
months after the end of the relevant accounting year
Large UK companies pay most of their tax close to the end of the
relevant accounting year
→ Tax liabilities & benefits treated as occurring in the same year
Capital Budgeting

Inflation can have a serious effect on investment decisions by
reducing the real value of future cash flows
Deflate nominal cash flows by the general rate of inflation to obtain
real cash flows

Nominal discount rate = 10%
Expected inflation = 4%
Real discount rate = 1.10/1.04 – 1 = 5.8%
Next year’s sales = £100 in today’s prices
PV using real cash flow = 100/1.058 ~ £94.50
PV using nominal cash flow = 100×1.04/1.10 ~ £94.50
This example illustrates how NPV obtained by discounting real
cash flows with a real cost of capital is identical to NPV obtained
by discounting nominal cash flows with a nominal cost of capital

Investment Appraisal ApplicationSensitivity Analysis
Sensitivity Analysis is a method of assessing an investment
project by evaluating how responsive the outcome of the project
appraisal is to changes in relevant variables…
Conventional approaches:
• Change each project variable by a set amount and
recalculate NPV
• Change each project variable such that NPV = 0, and
evaluate the magnitude of change required
Some rules: Change one variable at a time, and change it in the
direction that adversely affects NPV
Equation 1
Investment Appraisal ApplicationSensitivity Analysis
Example:
Capital Budgeting
Using Equation 1, we can show that𝜕𝑁𝑃𝑉
𝜕𝑆= 𝑁 × 𝐶𝑃𝑉𝐹12,4 = 800,000 × 3.037 = 2,429,600
So, a one $ drop in sales price leads to a $2.4 m drop in NPV
(which will make it negative)
This implies that a percent drop in price (=$0.092) will lead to a
$223,523 drop in NPV = 29% drop
A similar analysis shows that if the initial cost increases by a
percent, NPV drops by 9% only
Sales price is therefore a key variable

A similar process could be carried out for changes to any other
of the variables (for example, how low would volume of sales
need to get for NPV to be zero, and so forth)
The hard part is interpreting the interaction between all these
uncertainties!...but if you look at impact of 1% change on the
NPV you should be quick to identify the main risk factors

Investment Appraisal in Practise
Companies don’t always make use all of the sorts of analysis we
have looked at today
In part this almost certainly reflects the large amount of
uncertainty associated with predicting the future!
The payback method is most common (although often
accompanied by some sort of discounted cash flow method)
Capital Budgeting
Investment Appraisal in Practise
It is surprising how few companies formally adjust calculations
for inflation
Drury et al, 1993, suggest only some 27%
The use of more advanced sensitivity or probability analysis
also appears to be relatively rare
Although surely in part because managers see it as being of
relatively little practical benefit

What is risk?
Risk, in traditional terms, is viewed as something ‘negative’. Webster’s dictionary, for instance, defines risk as “exposing to danger or hazard”.
The Chinese symbols for risk, reproduced below, give a much better description of risk
危機
The first symbol is the symbol for danger, while the second is the symbol for opportunity, making risk a mix of danger and opportunity.
You cannot have one, without the other

In finance it is something different than
expected.
It is measured by standard deviation of
returns.
In finance, we call this measure ‘volatility’

Mean-variance framework
expected returns measured by mean of returns
and risk measured by standard deviation of returns
Mean-variance approach holds when:
investors maximize the expected utility,
prefer more to less,
are risk averse,
and when either security returns are normally distributed or utility function is quadratic

Measuring Risk and Return
Basis for Portfolio Theory
If volatility V[A] is a correct measure of risk, then in theory
V[A] > V[B] → E[A] > E[B]
Otherwise, there won’t be any incentive to take risk
The underlying assumption is: Investors are risk-averse
Expected return is liked – variance is disliked
This is the essence of the so-called mean-variance analysis

A theoretic approach is to try to maximise the investor’s utility
subject to the risk-return tradeoff (constraints)
→ We will consider the investor’s indifference curve on the risk-
return plane
A more practical approach is to come up with a target expected
return, and then find the weights that minimise portfolio risk

Nobel Prize in 1990

As a result, the expected return is constant
The variance of the risk-free asset is zero
The covariance with other assets is zero
(Can you prove these?)

short-term Treasury bills as a proxy for the risk-free interest rate

1) Locate the tangency portfolio TG
2) All investors maximise their utility by choosing the “right”
mix of TG and the risk-free asset

An average stock (or the market portfolio) has a beta = 1.0.
Beta shows how risky a stock is if the stock is held in a well-diversified
portfolio.
β=1 → stock has average risk.
β>1 → stock is riskier than average.
β<1 → stock is less risky than average.
β=0 → risk free assets (e.g., Treasury bills)
Capital Asset Pricing Model

The beta of a portfolio (βP) is the weighted average of the betas from its
constituent securities.
Example:
You have $6,000 invested in IBM, $4,000 in GM. You estimate that IBM
has a beta of 0.95 and GM has a beta of 1.15.
What is the beta of your portfolio?
βP = 0.6*0.95 + 0.4*1.15 = 1.03

Beta estimates:
Betas are sometimes as large as 2-3 for highly volatile stocks
Low beta: Stable stocks, less affected by business cycles, e.g.
consumer products, and utilities
High beta: ‘Tech’ stocks, financial sector
Negative beta: precious metals and precious-metal-related
stocks, e.g. gold and gold exchange-traded funds (ETF)

Investors use CAPM to calculate the expected rate of return on a
security – asset valuation (pricing)
Let’s look a the following data:
Beta of British Airways plc = 1.17
Yield of short-dated Treasury bills = 3.1%
Market risk premium = 4.2%
The expected return on BA = 3.1% + (1.17 × 4.2%) = 8%

The asset beta is always lower than the equity beta, unless a
company is all-equity financed
If we assume that companies do not default on their interest
payments we can take the debt beta to be zero, and hence
𝛽𝑎 = 𝛽𝑒 ×𝐸

We can use this formula to determine the new equity beta when
there is a change in capital structure

It is planning a leveraged buyout , where it will increase its debt/equity ratio of 8. If the tax rate is 40%, what will the beta of the equity in the firm be after the LBO?
• Unlevered Beta = 1.20 / (1 + (1-0.4) (50/100)) = 0.923076923
• New Beta = 0.923 (1 + (1-0.4) (8)) = 5.35

Relationship with allocation efficiency:
Assumptions:
◊ No transaction costs
◊ Information acquisition incurs no cost
If the information suggests that a share is undervalued, i.e.P* > Pt, then some investors will buy it, and the price will rise
Similarly, when the stock is overvalued
If every investor shares the same set of information, themarket will be in equilibrium at any time: P* = Pt

Can investors ‘beat the market’?
If prices reflect all relevant information, any changes must be
due to an arrival of new information – which seems to be random
EMH rules out any possibilities of investors making sustained abnormal profit
EMH does not rule out the possibility of obtaining profit from the
arrival of new information
If there is actually some opportunity to make extra money, it
should disappear very quickly (thanks to the quick dissemination
of information)

What would be your best estimate of Pt+1?
Answer: Pt because you don’t know what the “news term” is
going to be
We say that price is a martingale:
𝐸[𝑝𝑡+1 Ω𝑡] = 𝑝𝑡
where the expectation is conditional on all available
information at t (Ω𝑡)
Market Efficiency
Market Efficiency
A simple example:
𝑝𝑡+1 = 𝑝𝑡 + 𝜀𝑡+1, 𝑤𝑖𝑡ℎ 𝐸[𝜀𝑡+1 Ω𝑡] = 0
Random term = noise term = “news” term
We can then study the property of return
∆𝑝𝑡+1 = 𝜀𝑡+1
𝐸∆𝑝𝑡+1
𝑝𝑡 Ω𝑡 = 𝐸
𝜀𝑡+1
𝑝𝑡 Ω𝑡 =

If price is a martingale, then return is a martingale difference:
𝐸 𝑅𝑡+1 Ω𝑡 = 0
By the law of iterated expectation, it follows that
𝐸 𝑅𝑡+1 = 0
But this barely makes any senses economically.

This random walk model assumes that the “news term” is
identically and independently distributed:
𝜀𝑡~𝐼𝐼𝐷(0, 𝜎2)
A “step” from Pt to Pt+1 is random, thus the terminology
Return will also be iid since ∆𝑝𝑡+1 = 𝜀𝑡+1
This implies that return shows no autocorrelation, i.e. return at
time t+1 must not show any correlation with return at time t

Louis Bachelier is a pioneer in the study of financial mathematics
His model assumes further that
𝜀𝑡~𝑁𝐼𝐷(0, 𝜎2)
i.e. “news” is normally and independently distributed with mean
zero and constant variance
Normality is convenient (two-parameter distribution), but also
highly controversial
This has been a building block of modern finance

Predictability as an evidence of inefficiency
The random walk model implies that returns must not be
predictable
If returns are predictable, then it might be possible to
systematically generate excess returns
→ Long positive return / short negative return
Unpredictability is sufficient, but not necessary, for
market efficiency
→ Small average excess returns might not generate net gains once
costs have been taken into account

CASH FLOW:The difference between money received and money paid.
Often confused with accounting profits. 2 issues: 1. Profits are shown as they are earned, not when the cash is paid2. The cash outflows are divided into: current expenses and capital expenses. Current
expenses are deducted when calculating profit. Capital expenses are not (they are deducted over number of years).
Thus profits include some cash flows and excludes others, they are reduced by depreciation charges (which are not cash flows at all)
Always estimate cash flows on after tax basis.
Cash flows are recorded when they occure and not when work is undertaken or liability is incured.

EXERCISES
Question 1
A company is financed by bonds and ordinary shares.
The 12% bonds are redeemable in 5 years’ time at par. Annual interest has
just been paid. The current ex-interest market price of the bond is £114.
Corporation tax is 28%.
The ex-dividend ordinary share price is £3.14 and the most recent dividend
was 35 pence per share. Both dividend and share price are expected to
increase by 7% per year for the foreseeable future.
The company has 5,000 redeemable bonds (par value £100) and 225,000
ordinary shares (par value £1).
(a) Calculate the cost of debt. [Hint: remember the ‘tax-shield’.]
(b) Calculate the cost of equity.
(c) Calculate the company’s WACC.
Question 2
At January 2012 a company’s sources of debt and equity finance are
summarised as follows:
7% (DP) preference shares (£1) £400,000
8% bonds (redeemable January 2021, par [ ] £100) £600,000
9% bank loan £500,000
Ordinary shares (£1) £400,000
By making use of this and the following information calculate the
company’s WACC at market prices.
[Hint: remember the ‘tax-shield’.]

following information.
a) Draw the probability distribution for X, and for Y. Comment on their
shape.
b) Calculate the expected return for each security.
c) Calculate the expected risk of each security.
Question 5
You are considering investing in two securities, X and Y, and have the
following information.
a) Do the above data conform to the risk-return trade-off?
b) Calculate the expected return and standard deviation for the following
portfolios:
i. 100 per cent X;
ii. 75 per cent X and 25 per cent Y;
iii. 50 per cent X and 50 per cent Y;
iv. 25 per cent X and 75 per cent Y;
v. 100 per cent Y.
c) Plot your answers on the risk-return plane, and comment on the benefit
of diversification.
Question 6
Stock A has a beta of 1.0, and very high idiosyncratic risk. If the expected
return on the market is 20%, what will be the expected return on Stock A
according to the CAPM?
Question 7
Suppose you estimate the CAPM model for Stock B. Your result shows that
this stock has beta of 1.4, and the standard deviation of the error term of
7%. Assume that the standard deviation of the market is 12%. What is the
total standard deviation of Stock B?
Question 8
Suppose you invested £600 in Stock C, and £400 in Stock D. Stock C’s beta
is 1.2, and Stock D’s beta is 0.9. What is the beta of your portfolio?
Question 9
You formed a portfolio by combining the risk-free asset and Stock Z. The
risk-free rate is 6%, while the expected return of Stock Z is 22%. The
volatility of Stock Z is 40%. If your portfolio shows the standard deviation
of 30%, what is the expected return on your portfolio?
Question 10
A firm has an equity beta of 1.3, and is currently financed by 25% debt and
75% equity. What will be the company’s new equity beta if the company
changes its financing to 33% debt and 67% equity? Assume corporate tax
is 30%.
Question 11
A company has in issue bonds which are convertible in 3 years’ time into
25 ordinary shares per bond. If not converted, they will be redeemed in 6
years’ time at par. The bonds pay 9% interest per year and currently have a
market price of £90.01. The current ordinary share price is £3.24. If holders
of ordinary bonds of a similar risk class require a return of 13% per
annum:
(a) Are bond holders likely to convert?
(b) What is the expected annual growth rate of the ordinary share price?
(c) Calculate the minimum growth rate in the ordinary share price
necessary to make conversion an attractive option.
(d) Calculate the implicit conversion premium

Business risk – the risk associated with profits and earnings changing due to the sector the company operates in (systematic risk)
Financial risk – the risk associated with increased gearing due to uncertainty over interest payments on debt capital
Bankruptcy risk – the risk of a company becoming insolvent due to an inability to meet interest payments on debt capital
Risk-free rate – the return that can be achieved for certain (on say government bonds)

Capital Structure
Gearing, risk and required rate of return
The diagram illustrates how investors’ required rates of return on equity increase with a company’s gearing:
i. The risk-free rate remains constant
ii. Business risk remains constant, the level reflecting the company’s sector
iii. Financial risk increases with gearing, reflecting the increasing effect of interest rate changes as the company’s debt levels
increase (potentially adversely affecting profits)
iv. Bankruptcy risk is shown for high levels of gearing as investors start to face risks of the company entering liquidation (and
potentially losing everything)
That was for equity holders
For holders of debt the only risk is that of bankruptcy, since interest payments on debt are guaranteed
Even then, debt holders face less bankruptcy risk than equity holders because they are higher in the hierarchy of creditors if the company were to be liquidated

Traditional approach is often referred to as ‘trade-off theory’
Some simplifying assumptions:
No taxation
Finance is either perpetual debt (interest payments only) or ordinary shares
Companies can change their financial structure costlessly
All earnings paid as dividends
Constant risk over time
Earnings and dividends do not grow

Theories of Capital StructureTraditional approach
Capital Structure
With no gearing the WACC is equal to the
cost of equity
As gearing increases the WACC decreases to reflect the cheaper cost
of finance
At some point the increased financial risk
(interest rate) associated with ever higher gearing starts
to increase WACC
At very high levels of gearing bankruptcy risk further increases WACC
optimal capital structure exists
(min WACC)
Miller & Modigliani (M&M) (1958) proposed a model that suggested that WACC remains constant for all levels of gearing
By adding the additional assumption of perfect capital markets to the previous model (which means firms can always borrow more) M&M assumed away bankruptcy risk…
Since M&M(i) implies a constant WACC it is often referred to as their “irrelevance” theory, i.e. the choice of capital structure doesn’t matter

Capital Structure
With no bankruptcy risk the cost of debt remains
constant. The cost of debt is independent of the level
of gearing
As gearing increases the cost of equity increases
linearly to reflect increased financial risk
The WACC remains constant. The reduced cost of debt finance is exactly offset by the
increased financial risk associated with higher
gearing levels
WACC is independent of capital structure
(capital structure is irrelevant)
Miller and Modigliani (i)
Assumptions
By issuing 1 security rather than 2, company diminishes investor choice. This does not reduce value if:
– Investors do not need choice, OR
– There are sufficient alternative securities
Capital structure does not affect cash flows e.g...
– No taxes
– No bankruptcy costs
– No effect on management incentives

Since investors can replicate what company does, why
would they pay more for firm with leverage?
The many assumptions of M&M(i) are clearly implausible
In their paper Miller & Modigliani acknowledge that the simplifications are implausible, yet necessary in order to start developing formal models of capital structure
Their second capital structure paper, Miller & Modigliani (ii) (1963), considers the tax shield associated with debt finance

Interest Pmt 0 100
Pretax Income 1,000 900
Taxes @ 40% 400 360
Net Cash Flow $600 $540
Example - You own all the equity of Space Babies Diaper Co. The company has no debt. The company’s annual cash flow is $1,000, before interest and taxes. The corporate tax rate is 40%. You have the option to exchange 1/2 of your equity position for 10% bonds with a face value of $1,000.
Should you do this and why?
Total Cash Flow
All Equity = 600
*1/2 Debt = 640
(540 + 100)
Interest Tax Shield- Tax savings resulting from deductibility of interest payments.

Consider the following story:
The announcement of a stock issue drives down the stock price because investors believe managers are more likely to issue when shares are overpriced.
Therefore firms prefer internal finance since funds can be raised without sending adverse signals.
If external finance is required, firms issue debt first and equity as a last resort.
The most profitable firms borrow less not because they have lower target debt ratios but because they don't need external finance.

Note: the stylised share price (the green line) implies the market reacted positively to the
dividend announcement, since initially the share price increases. (It could have fallen initially if
the market reacted negatively to the dividend announcement).
When the share goes ex dividend its price will always drop.
1. Firms have longer term target dividend payout ratios.
2. Managers focus more on dividend changes than on absolute levels.
3. Dividends changes follow shifts in long-run, sustainable levels of earnings rather than short-run changes in earnings.
4. Managers are reluctant to make dividend changes that might have to be reversed.

…what matters is simply the overall return on equity
Since investors do not need dividends to convert shares to cash they will not pay higher prices for firms with higher dividend payouts.
In other words, dividend policy will have no impact on the value of the firm.

Dividends as Signals
Dividend increases send good news about cash flows and earnings. Dividend cuts send bad news.

Clientele Effect
There are natural clients for high-payout stocks,

their demand for a dividend paying stock.

Tax Consequences
Companies can convert dividends into capital gains by shifting their dividend policies.
If dividends are taxed more heavily than capital gains, taxpaying investors should welcome such a move and value the firm more favorably.
In such a tax environment, the total cash flow retained by the firm and/or held by shareholders will be higher than if dividends are paid.

Consider an European put option with time to expiry of 1 year, and a strike price of 110.
The current price of the underlying is 100. Divide the time to expiry into two 6-month intervals.
Suppose that in each interval, the price can either rise by 10 or fall by 10, with equal probabilities.
The risk-free rate is 5% per annum, simply compounded.
The price movements can
be represented by a diagram
called a binomial tree.
An underlying assumption
is that the underlying price
follows a binomial process .
The value calculation proceeds backwards from T to t. Each step involves:
finding the terminal value of the option;
calculating its expected value of the option; and finally
discounting it by the risk-free rate (make sure that you use the right rate).

Consider a stock whose price is S0 and option on the stock whose current price is f.
Option lasts for time T, and in that time the stock price moves to either S0U (where U > 1) or to S0D (where D < 1).
fU is option payoff if stock moved to S0U and fD option payoff is stock moved to S0D.
Consider a portfolio consisting of a long position in Δ shares and a short position in one option.
Calculate Δ that makes the portfolio riskless (i.e. portfolio has the same payoff regardless if the stock price increased or
decreased):

For arbitrage opportunities not to exist the riskless portfolio must earn risk-free interest rate.
If r is the risk-free interest rate, then the present value of the portfolio is:
(𝑆0𝑈∆ − 𝑓𝑈)exp(−𝑟𝑇) = (𝑆0𝐷∆ − 𝑓𝐷)exp(−𝑟𝑇)
whereas the cost of creating this portfolio today is:
𝑆0∆ − 𝑓
Therefore:
𝑆0∆ − 𝑓 = (𝑆0𝑈∆ − 𝑓𝑈)exp(−𝑟𝑇)
𝑓 = 𝑆0∆(1 − 𝑈𝑒𝑥𝑝 −𝑟𝑇 ) + 𝑓𝑈exp(−𝑟𝑇)
Let’s substitute 𝑓𝑈−𝑓𝐷

Risk Neutral Valuation
Utility:
The usual assumptions are that u’(.) > 0 and u”(.) < 0 .
Utility Function
In risk-neutral world, risk-neutral investors do not increase the expected return they require from an investment to
compensate for increased risk.
in economics it is the fundamental measure of value.
Utility function u(x): tells us the unit of “satisfaction” that x gives us.
in finance, x usually represents the amount of money or profit.
two assumptions are normally required regarding the function u(.) :
1) slope of the function;
2) curvature, i.e. how the function “bends”.
This implies positive but decreasing marginal utility.
When x is random, then u(x) becomes a random variable.
The assumption about the curvature becomes critical as it implies the view towards risks.
In this aspect, we may classify utility functions according to their risk preferences.

Risk Neutral Valuation
Risk Preferences
Risk neutral Individuals who are indifferent between the lottery and the sure sum of $50
𝑢 50 = 0.5 × 𝑢 0 + 0.5 × 𝑢(100)
A general condition for risk
neutrality is that u”(.) = 0 (linear).
Real-life examples of risk preferences:
Risk-averse: Individual investors, pension
funds;
Risk-loving: Hedge funds;
Risk-neutral: Institutional investors, large
companies – Management being risk-
loving while owners being risk-averse.
Binomial model
Risk-averse individuals prefer receiving the sure sum of $50 to being given a lottery whose expected return is $50.
Suppose that an individual holds a lottery that yields $0 or $100 with equal probabilities.
This lottery gives the expected return of $50 = 0.5*$0 + 0.5*$100
𝑢 50 > 0.5 × 𝑢 0 + 0.5 × 𝑢(100)
Risk-loving individuals prefer the lottery to the sure sum of $50.
𝑢 50 < 0.5 × 𝑢 0 + 0.5 × 𝑢(100)

Risk Neutral Valuation
Risk neutrality proves very interesting since it implies that investors only care about expected returns, and not risks
associated with the investment.
Suppose there are only two assets in the economy: one risky (‘stock’) and the other riskless (‘bond’).
Risk-neutral investors will hold the stock alone – no matter how risky it is – provided that such a stock gives a higher
expected return than the bond.
If we’re willing to assume that everybody in the world is risk-neutral, then it must be the case that the returns on both
assets must be equal.
A risk-neutral world has two features that facilitate pricing derivatives:
(1) Expected return on stock (or any other instrument) is risk-free
(2) The discount rate used for the expected payoff on an option (or any other instrument) is risk-free rate.
Let 𝑝 =𝑒𝑟𝜏−𝐷
𝑈−𝐷be interpreted as the probability of an up movement in a risk-neutral world..
Thus the expected future payoff from an option in risk neutral world is:

Two-Step Binominal Trees
In order to calculate the option price at the initial node of the tree, one needs to start
with calculating option price at the final nodes and then working out option price at
the earlier nodes.
Example:Consider 2-year European put option with a strike price of 52, whose stock is currently trading at 50.
There are two 1-year steps. In each step stock price can increase by 20% or decrease by 20%. The risk-free interest rate is 5%.

Put-Call Parity
The put-call parity defines a relationship between the price of a call and a put – both with identical K and t.
It allows us to calculate c from p, and vice versa. The underlying assumption is that there is no arbitrage opportunities.
The parity is given by: 𝑝𝑡 + 𝑆𝑡 = 𝑐𝑡 + 𝐾𝑒−𝑟𝜏
We can prove this by considering two portfolios which always give the same payoffs at maturity:
(1) A put & a stock
(2) A call & a zero-coupon bond (or cash)
It can be shown that both portfolios give the same payoffs regardless of the terminal stock price.
ST > K ST < K

Question 1
The ordinary shares of NTC currently trade at 80p. The dividend per share
is 15p and has been constant at this level for 10 years.
NTC plans to finance a new investment opportunity out of retained
earnings. This will mean that for the next two years the dividend per share
will fall to 10p.
The benefits of the investment will mean that from year 3 onwards
dividend per share will increase to 18p per share for year 3 and
subsequent years.
Assuming all this information is known to shareholders; use the dividend
growth model to calculate a fair share price.
Question 2
It is 31 January 2009 and the managers of Watsons are considering a
change in the company’s dividend policy. Earnings per share for 2008 for
the company were 22.8 pence, and the finance director has said that he
expects this to increase to 25.0 pence per share in 2009. The increase in
earnings per share is in line with market expectations of the company’s
performance. The pattern of recent dividends, which are paid each year on
31 December, is as follows:
The Managing Director has proposed that 70% of earnings in 2009 and
subsequent years should be retained for investment in new product
development. It is expected that, if this proposal is accepted, the dividend
growth rate will be 8.75%. Watson’s cost of equity capital is estimated to
be 12%.
Calculate the share price of Watson’s in the following circumstances.
(a) The company decides not to change its current dividend policy.
(b) The company decides to change its dividend policy as proposed by the
Managing Director and announces the change to the market.

8. GenCorp, an automorive parts manufacturer, currently has $25 million in outstanding debt and has 10 million shares
outstanding. The book value per share is $10, while the market value is $ 25. The company is currently rated A, its
bonds have a yield to maturity of 10%, and the current beta of the stock is 1.06. The six-month T.Bill rate is 8% now, and
the company's tax is 40%.
a. What is the company's current weighted average cost of capital?
b. The company is considering a repurchase of 4 million shares at $25 per share with new debt. It is estimated that this
will push the company's rating down to a B (with a yield to maturity of 13%). What will the company's weighted average
cost of capital be after the stock repurchase?
(a) Current Cost of Equity = 8% + 1.06 (5.5%) = 13.83%
Current Cost of Debt = 10% (1-0.4) = 6.00%
Current Cost of Capital = 13.83% (250/275) + 6.00% (25/275) = 13.12%
(b) If the firm borrows $ 100 million and buys back $ 100 million of stock
New Debt/Equity Ratio = 125/150 = 0.833333333
Unlevered Beta = 1.06/(1+0.6*.10) = 1.00
New Beta = 1 (1 + 0.6*0.8333) = 1.50
Cost of Equity = 8% + 1.50 (5.5%) = 16.25%
Cost of Capital = 16.25% (150/275) + 13% (1-.4) (125/275) = 12.41%

9. Pfizer, one of the largest pharmaceutical companies in the United States, is considering what its debt capacity is. In March
1995, Pfizer had an outstanding market value of equity of $ 24.27 billion, debt of $ 2.8 billion and a AAA rating. Its beta was
1.47, and it faced a marginal corporate tax rate of 40%. The treasury bond rate at the time of the analysis was 6.50%, and
AAA bonds trade at a spread of 0.30% over the treasury rate. Market premium equals 5.5%.
a. Estimate the current cost of capital for Pfizer.
b. It is estimated that Pfizer will have a BBB rating if it moves to a 30% debt ratio, and that BBB bonds have a spread of 2%
over the treasury rate. Estimate the cost of capital if Pfizer moves to its optimal.
c. Assuming a constant growth rate of 6% in the firm value, how much will firm value change if Pfizer moves its optimal?
What will the effect be on the stock price?
d. Pfizer has considerable research and development expenses. Will this fact affect whether Pfizer takes on the additional
debt?
a. Cost of Equity = 6.50% + 1.47 (5.5%) = 14.59%
Cost of Capital = 14.59% (24.27/(24.27+ 2.8)) + 6.8% (1-0.4) (2.8/(24.27+2.8)) =
13.50%
b. If Pfizer moves to a 30% debt ratio,
New debt/equity ratio = 30/70 = 42.86%
Unlevered Beta = 1.47/(1+0.6*(2.8/24.27)) = 1.37
Unlevered Beta= beta1/(1+(1-Tc)(D1/E1))
New Beta = 1.37 (1+0.6*0.4286) = 1.72
New Beta = unleveler beta * (1+ (1-Tc)(D2/E2)
New Cost of Equity = 6.5% + 1.72 (5.5%) = 15.96%
New Cost of Capital = 15.96% (0.7) + 8.5% (1-.4) (0.3) = 12.70%
c. If the savings grow at 6% a year in perpetuity, the change in firm value can be computed as follows –
Savings each year = (.1350-.1270) (24.27 + 2.8) = 0.21656 ! $ 216.56 million
PV of Savings with 6% growth = (216.56*1.06)/(.127-.06) = $3,426 ! $ 3.4 billion
Increase in Stock Price = 3426/24270 = 14.12% ! Stock Price will increas by 14.12%
d. The need for R& D increases the need for flexibility; therefore, Pfizer may not go to this higher optimal
debt ratio, the cost of capital notwithstanding.
