Trang 2Cash Flows as Random Variables
“Risk” in every day usage: the probability that something bad will
happen
“Risk” in financial theory: Associated with random variables and their probability distributions
Trang 3Cash Flows as Random Variables
Risk – the chance that a random variable will take on a value
significantly different from the expected value
– In capital budgeting the future period's cash flow estimate is a random variable

Trang 4Figure 12-1 The Probability Distribution of a Future Cash Flow as a
Random Variable
Trang 5Cash Flows as Random Variables
The NPV and IRR are random variables with their own probability distributions
– Actual value may be different than the mean
– The amount the actual value is different from expected is related to the variance or standard deviation

Risk Aversion
Changing the Nature of a Company
– A company is a portfolio of projects
– Ignoring risk when undertaking new projects can change the firm’s overall risk characteristics

Trang 10Scenario/Sensitivity Analysis
Select a worst, most likely, and best case for each cash flow
Recalculate the project's NPV (or IRR) under several scenarios
– Gives an intuitive sense of the variability of NPV
– Also called sensitivity analysis

Trang 13Decision Tree Analysis
Decision Tree: A graphic representation of a project in which certain events have multiple outcomes
Decision Tree Analysis – Develops a probability distribution of NPV given the probabilities of certain events within the project
13
Trang 14Computer (Monte Carlo) Simulation
Assume separate probability distribution for each cash flow
Computer draws observation from each and calculates NPV
Sort outcomes into histogram of probability distribution of NPV (next slide)
Drawbacks
– Probability distributions are difficult to estimate
– Cash flows tend to be correlated
– Interpretation of results is subjective

The Wing Foot Shoe Company is considering a new running shoe A market study indicates
a 60% probability that demand will be good and a 40% chance that it will be poor
C0 is $5M Cash inflows are estimated at $3M per year for three years at full manufacturing capacity if demand is good, but just $1.5M per year if it’s poor Wing Foot’s cost of capital is 10%
Develop a rough probability distribution for NPV.

Wing Foot now feels there are two possibilities along the upper branch
If first year demand is good, there’s a 30% chance it will be excellent in the second and third years, and a
$1 million factory expansion will generate cash inflows of $5 million in years 2 and 3
That means net cash inflows will be $4 million in year 2 and $5 million in year 3
A decision tree for the project with this additional possibility is on the next slide

Trang 25Real Options
An option is the right or ability to take a certain course of action
A real option is a course of action that usually
– Improves financial results under certain conditions
– Exists in a real, physical business sense
– Frequently occurs in capital budgeting
– Generally increases a project's expected NPV
25
Trang 26The Abandonment Option
A poorly performing project can sometimes be abandoned
– Usually by redeploying project resources to another use
Avoids continuing losses along a decision tree path
It usually takes planning early in a project’s life to preserve an abandonment option
Trang 27Valuing Real Options
Real Options usually
– have definite costs early in projects
– Create additional income along only one path
– The chance of more income increases NPV
An option’s value is at least the increase in NPV less the option’s cost
– But the real option may be worth more if it also reduces project risk (e.g abandonment )
Trang 28Valuing Real Options
The Risk Effect is Tricky –
An Approach Through Rate of Return
higher NPV
Trang 29Designing Real Options into Projects
Abandonment option
– Usually increase NPV and lower risk
– Contract obligations can make abandonment tough
Expansion options
– Often require little or no early commitment
– Should be planned in whenever possible
Investment timing options
– Permit delaying investment until more certain about surrounding issuesFlexibility options
– Preserve ability to respond to changing business conditions

Trang 30Incorporating Risk Into Capital Budgeting
A higher k leads to lower NPV reducing the chance of project acceptance
A higher k leads to a lower chance that IRR>k reducing probability of project acceptance
Trang 31Incorporating Risk Into Capital Budgeting
Riskier Projects Should Be Less Acceptable
– Using a higher, risk-adjusted rates for risky projects lowers their chance of acceptance
The Starting Point for Risk-Adjusted Rates is the firm’s current risk level reflected
in its cost of capital
31
Trang 32Incorporating Risk Into Capital Budgeting
Relating Interest Rates to Risk
– Investors demand a higher risk premiums higher interest rates if they are to bear more risk
Trang 33Incorporating Risk Into Capital Budgeting
Choosing the Risk-Adjusted Rate for Various Projects
– An arbitrary, subjective process
Three categories of increasing risk
– Replacements – low risk, use cost of capital
– Expansion projects - slightly more risky than the current level
– New ventures – generally involve a lot more risk
33
Trang 34Estimating Risk-Adjusted Rates
Using CAPM
The project as a diversification
– If viewed as a collection of projects, a new
venture diversifies the firm
– A new venture also diversifies the stockholders’ investment portfolios
Trang 35Estimating the Risk-Adjusted Rate Through Beta
The Security Market Line (SML) can be used to determine a risk-adjusted rate for a new venture
SML: kx = kRF + (kM - kRF) bX
– bX = beta = the measure of a company's systematic risk
If a project is viewed as a business in a particular field, use a beta common to that field to estimate a risk-adjusted rate for project analysis
35
Trang 36Estimating Risk-Adjusted Rates
Using CAPM
The project as a diversification
Diversifiable and non-diversifiable risk for projects
Some risk diversified away within the firm's portfolio of projects
Some risk diversified away by the shareholders' investment portfolios The remaining risk is systematic risk

Orion Inc makes radio communications equipment
beta = 1.1 cost of capital = 8%
Considering a venture into risky military radios
Military radio market is dominated by
Milrad Inc - 60% market share, beta = 1.4
Antex Radio Corp - 20% market share, beta = 2.0
Both make only military radios
kM = 10% , kRF = 5%
C0 = $10M, Ci= $3M n = 5 years

Trang 40Problems with the Theoretical Approach
It is often difficult to find a pure play firm from which to obtain an appropriate beta
using the accounting beta method
Systematic risk may not be only important risk
Trang 41Certainty Equivalents (CE)
For every cash flow management develops a lower risk free (certain) figure that is as attractive
as the forecast risky figure.
Alternatively choose a CE factor (0< 1) for each cash flow and multiply.
Trang 42A Final Comment on Risk in Capital Budgeting
Virtually every firm of any size uses capital budgeting techniques
– But few explicitly include risk
Business managers do recognize risk but they do it through subjective judgments
