Payback A = 1 year Payback B = 2 years Payback C = 4 years c. A and B 2. a. When using the IRR rule, the firm must still compare the IRR with the opportunity cost of capital. Thus, even with the IRR method, one must specify the appropriate discount rate. b. Risky cash flows should be discounted at a higher rate than the rate used to discount less risky cash flows. Using the payback rule is equivalent to using the NPV rule with a zero discount rate for cash flows before the payback period and an infinite discount rate for cash flows thereafter. 3. r = -17.44% 0.00% 10.00% 15.00% 20.00% 25.00% 45.27% Year 0 -3,000.00 -3,000.00 -3,000.00 -3,000.00 -3,000.00 -3,000.00 -3,000.00 -3,000.00 Year 1 3,500.00 4,239.34 3,500.00 3,181.82 3,043.48 2,916.67 2,800.00 2,409.31 Year 2 4,000.00 5,868.41 4,000.00 3,305.79 3,024.57 2,777.78 2,560.00 1,895.43 Year 3 -4,000.00 -7,108.06 -4,000.00 -3,005.26 -2,630.06 -2,314.81 -2,048.00 -1,304.76 PV = -0.31 500.00 482.35 437.99 379.64 312.00 -0.02 The two IRRs for this project are (approximately): –17.44% and 45.27% Between these two discount rates, the NPV is positive. 28
