Answer:
Project X maximizes shareholder value (highest NPV) and has a MIRR of 14.27%.
Step-by-step explanation:
year cash flow project X cash flow project Y
0 -1,000 -1,000
1 100 1,000
2 320 110
3 400 55
4 700 45
WACC = 13%
Using an excel spreadsheet I calculated the projects' NPV, IRR and MIRR
NPV IRR MIRR
project X $45.65 15% 14.27%
project Y $36.82 16% 14.03%
The modified internal rate of return (MIRR) considers that the project's cash inflows are invested at the company's WACC and the initial investment is financed at a certain debt rate (in this case the same WACC).
