Incorporating risk (uncertain cash flows) into capital
budgeting analysis involves:
– applying techniques that assess the risk level of a project’s cash flows
Risk & Return
– using a risk-adjusted discount rate

RETURNS ON INVESTMENT
When an investment is made, there is the expectation that this investment will generate positive returns.
There are two different ways of measuring the return generated by an investment
1.
Dollar Returns
2.
Rate of Return
Lecture 07
DOLLAR RETURNS
The dollar return is the difference between the amount you receive at the end of the investment and the amount initially invested. Dollar Return Amount Received
Amount Invested

DOLLAR RETURNS (CONT.)
RATE OF RETURN
To fully understand this measure, you need two more pieces of information.
1.
The scale of the original investment.
2.
The length of time the investment has been held for.
A more useful measure is the rate of return:
Rate of Return
Dollar Return
Amount Invested
This gives a percentage answer which is much
easier to understand.

Dollar Return Amount Received - Amount Invested
It is offering a year-end dividend of $0.20 and the
[$0.20 $2.50] - $2.00 $0.70
year–end share price is expected to be $2.50
What is your investment return if held for a year, in dollar and percentage terms?

RETURNS AND RISK
RISK
Returns are closely related to risk.
– Investments are only undertaken if the expected return is high enough to compensate the investor for the perceived risk of the investment. Risk can be considered in different ways:
– Stand-Alone Risk. This is the level of risk when the asset / investment is considered alone
10
– Risk on a Portfolio Basis. The level of risk when the asset is just one of a number of items in a portfolio.
Risk is defined as:
– The possibility of exposure to loss or injury.
– Uncertainty regarding the outcome.

MEASURING RISK
Risk is often measured using probability.
A probability distribution is a list of all the possible outcomes and the probability that each will occur.
Probabilities can also be used to create a Payoff Matrix which associates probabilities with rates of return
