CHAPTER 27 APPENDIX –
Without the fee, the lockbox system should be accepted. To calculate the NPV of the lockbox with
With the fee, the lockbox system should not be accepted.
12. The minimum number of payments per day needed to make the lockbox system feasible is the
number of checks that makes the NPV of the decision equal to zero. The average daily interest rate
is:
The present value of the savings is the average payment amount times the days the collection period
is reduced times the number of customers. The costs are the transaction fee and the annual fee. Both
are perpetuities. The total transaction costs are the transaction costs per check times the number of
checks. The equation for the NPV of the project, where N is the number of checks transacted per day,
is:

1. a. Decrease. This will lower the trading costs, which will cause a decrease in the target cash
b. Decrease. This will increase the holding cost, which will cause a decrease in the target cash
c. Increase. This will increase the amount of cash that the firm has to hold in non-interest bearing
d. Decrease. If the credit rating improves, then the firm can borrow more easily, allowing it to

f. Either. This depends somewhat on what the fees apply to, but if direct fees are established, then
the compensating balance may be lowered, thus lowering the target cash balance. If, on the
