Based on its profitability index, Project B should be accepted.

BRIEF EERCISE 12-6 (Continued) Revised estimate value of net annual cash flows value of salvage value 1% Discount Factor $39, 6.4956.3549 ($253,37) ( ) ( 253,37) ( 26,) ($ (6,693) The original net present value was projected to be a positive $14,915; however, the revised estimate is a negative $6,693. The project is not a success. BRIEF EERCISE 12-7 When net annual cash flows are expected to be equal, the internal rate of return can be approximated by dividing the capital investment by the net annual cash flows to determine the discount factor, and then locating this discount factor on the present value of an annuity table. $176,/$33,74 5.21636 By tracing across on the 7-year row we see that the discount factor for 8% is 5.2637. Thus, the internal rate of return on this project is approximately 8%. BRIEF EERCISE 12-8 When net annual cash flows are expected to be equal, the internal rate of return can be approximated by dividing the capital investment by the net annual cash flows to determine the discount factor, and then locating this discount factor on the present value of an annuity table. Since this exercise has a salvage value, not all cash flows are equal. In this case, the internal rate of return can be approximated by identifying the discount rate that will result in a net present value of zero. By experimenting with various rates, we determined that the net present value is approximately zero when a discount rate of approximately 9% is used.

BRIEF EERCISE 12-9 The annual rate of return is calculated by dividing expected annual income by the average investment. The company s expected annual income is: $13, $7, $6, Its average investment is: $47, + $1, 2 $24, Therefore, its annual rate of return is: $6,/$24, 25%

SOLUTIONS TO EERCISES EERCISE 12-1 (a) The cash payback period is: $56, $7,5 7.5 years The net present value is: value of net annual cash flows value of salvage value $ 7,5 27, 8% Discount Factor 5.74664.5427 $43,1 14,587 57,687 56, $ 1,687 (b) In order to meet the cash payback criteria, the project would have to have a cash payback period of less than 4 years (8 2). It does not meet this criteria. The net present value is positive, however, suggesting the project should be accepted. The reason for the difference is that the project s high estimated salvage value increases the present value of the project. The net present value is a better indicator of the project s worth.

(c) The present value of the intangible benefits was $3,441 (the increase in the net present value from a negative $13,95 to a positive $16,491). Rick s estimates of the value of these intangible benefits may be overly optimistic. In order for the project to be acceptable, the present value of the intangible benefits would only have to be $13,95. That is the amount by which the original estimate fell short of having a positive net present value.

It appears that many of the camp s costs are fixed; thus, when the number of players declines, cash inflows decline, but cash outflows don t decline proportionately.
