1. Project Selection - Midwest Water Works estimates that its WACC is 10.5 percent. The Company is considering the following capital budgeting projects:

Project A Size Rate of Return
A $1 million 12.0%
B 2 million 11.5
C 2 million 11.2
D 2 million 11.0
E 1 million 10.7
F 1 million 10.3
G 1 million 10.2
Assume that each of these projects is just as risky as the firm's existing assets, and the firm may accept all the projects or only some of them. Which projects should be accepted? Explain.
Since the firm's objective is to maximize the shareholder's value, they should accept the projects which provide the rate of return that is higher than the firm's WACC. Therefore, Midwest Water Works should accept Project A, B, C, D, and E because their rate of return is higher than 10.5%.
