12) Which of the following statements is FALSE?
A) When the investment cannot be delayed, the optimal rule is to invest whenever the
profitability index is greater than zero.
B) It is often better to wait too long (use a profitability index criterion that is too high) than to
invest too soon (use a profitability index criterion that is too low).
C) When the source of uncertainty that creates a motive to wait is interest rate uncertainty, the
hurdle rate is relatively easy to calculate.
D) When there is an option to delay, a good rule of thumb is to invest only when the profitability
index is at least 1.
13) Which of the following statements is FALSE?
A) The hurdle rate rule for projects with the option to delay uses a lower discount rate than the
cost of capital to compute the NPV, but then applies the regular NPV rule: Invest whenever the
NPV calculated using this lower discount rate is positive.
B) While using a hurdle rate rule for deciding when to invest might be a cost-effective way to
make investment decisions, it is important to remember that this rule does not provide an
accurate measure of value.
C) When the cash flows are constant and perpetual, and the reason to wait derives solely from
interest rate uncertainty, the hurdle rate rule of thumb is always exact. However, when these
conditions are not satisfied, the rule of thumb merely approximates the correct decision.
D) When a firm faces the same uncertainty for most of its investment decisions, using a single
profitability index criterion for all projects can provide a useful rule of thumb to account for cash
flow uncertainty.
14) The rate on a risk-free annuity that can be called at any time is known as the:
A) callable annuity rate.
B) callable auction rate.
C) callable hurdle rate.
D) risk-free rate.
