Discount Factor = DF = PV of $1
Discount Factors can

be used to compute the present value of any cash flow.

Valuing an Office Building

Step 1: Forecast cash flows
Cost of building =

C0 = 350
Sale price in Year 1 = C1 = 400
Step 2: Estimate opportunity cost of capital
If equally risky investments in the capital market
offer a return of 7%, then
Cost of capital = r = 7%

Risk and Present Value

Higher risk projects require a higher rate of

return
Higher required rates of return cause lower PVs

Rate of Return Rule Accept investments that offer rates of return

Rate of Return Rule

Accept investments that offer rates of return in

excess of their opportunity cost of capital

Rate of Return Rule

Accept investments that offer rates of return in

excess of their opportunity cost of capital

Example
In the project listed below, the foregone investment opportunity is 12%. Should we do the project?

Example
Suppose

we can invest $50 today and receive $60 in one year. Should we accept the project given a 10% expected return?

Example
You may invest $100,000 today. Depending on the

state of the economy, you may get one of three possible cash payoffs:

Example - continued
The stock is trading for $95.65.

Next year’s price, given a normal economy, is forecast at $110

Opportunity Cost of Capital Example - continued The stocks expected payoff leads to an expected return.

Opportunity Cost of Capital

Example - continued
The stocks expected payoff leads to

an expected return.

Opportunity Cost of Capital

Example - continued
Discounting the expected payoff at the

expected return leads to the PV of the project

Investment vs. Consumption

Some people prefer to consume now. Some prefer to

invest now and consume later. Borrowing and lending allows us to reconcile these opposing desires which may exist within the firm’s shareholders.

Investment vs. Consumption

The grasshopper (G) wants to consume now. The ant

(A) wants to wait. But each is happy to invest. A prefers to invest 14%, moving up the red arrow, rather than at the 7% interest rate. G invests and then borrows at 7%, thereby transforming $100 into $106.54 of immediate consumption. Because of the investment, G has $114 next year to pay off the loan. The investment’s NPV is $106.54-100 = +6.54
