Past final tips:
1. (Fall 07 final) Snowing Inc. is considering the following three projects. Its opportunity
cost of capital is 8%.
Project Initial
Investment
Cash Flow
Year 1
Cash Flow
Year 2
Cash Flow
Year 3
Cash Flow
Year 4
X -\$3,000 \$1,200 \$1,000 \$3,000 \$0
Y -\$1,000 \$0 \$1,200 \$0 \$1,000
Z -\$5,000 \$1,000 \$1,000 \$3,000 \$2,000
(a) Given that Snowing Inc. uses the payback rule with a cutoff period of 2
years, which project(s) would the firm choose?
A) Project X only
B) Project Y only
C) Project Z only
D) None of the projects
Solution: B
CF's Cumul. CF Discoun. CF Cumul. DCF
Project X
0 -3000 -3000 -3000 -3000
1 1200 -1800 1111.11 -1888.89
2 1000 -800 857.34 -1031.55

2 1000 -3000 857.34 -3216.73
3 3000 0 2381.5 -835.23
4 2000 2000 1470.06 634.83
The payback periods for the projects are: 2.27 years for Project X, 1.83 years for
Project Y, and 3 years for Project Z.
(b) If the firm uses a cutoff period of 3 years with the discounted payback
rule, which project(s) would Snowing Inc. accept?
A) Project X only
B) Projects X and Y
C) Projects X and Z
D) None of the projects
Solution: B
See table above.

Only pages 1-3 are available for preview. Some parts have been intentionally blurred.

The discounted payback periods for the projects are: 2.43 years for Project X,1.97 years for
Project Y, and 3.57 years for Project Z.
2. Which of the following statements is most likely correct for a project costing \$50000 and
returning \$14000 per year for five years?
a. NPV=\$3071.01
b. NPV=\$20000
c. IRR=2.8%
d. IRR is greater than 10%
CF0=-50000, c01=14000, f01=5->CPT IRR=12.38
3. You can continue to use your less efficient machine at a cost of \$8,000
annually for the next five years. Alternatively, you can purchase a more efficient
machine for \$12,000 plus \$5,000 annual maintenance over the next five years. At a
cost of capital of 15%, you should:
A) Buy the new machine and save \$600 annually
B) Buy the new machine and save \$388 annually
C) Keep the old machine and save \$388 annually
D) Keep the old machine and save \$580 annually
Solution: D
CF0=12000, C01=5000,F01=5-> NPV-> I=15->CPT NPV=28760.7755
EAC= PV/5 year annuity factor=28760.7755/3.352155=8579.7869
8579.7869-8000=579.7869
4. If a projectâ€™s IRR is 13% and the project provides annual cash flows of \$15000 for four
years, how much did the project cost?
a. \$44617
b. \$52200
c. \$60000
d. \$72747
