A company is considering a new project. The CFO plans to calculate the projects NPV by estimating the relevant cash flows for each year of the projects life (i.e., the initial investment cost, the annual operating cash flows, and the terminal cash flow), then discounting those cash flows at the companys overall WACC. Which one of the following factors should the CFO be sure to INCLUDE in the cash flows when estimating the relevant cash flows?

a. All sunk costs that have been incurred relating to the project.

b. All interest expenses on debt used to help finance the project.

c. The investment in working capital required to operate the project, even if that investment will be recovered at the end of the projects life.

d. Sunk costs that have been incurred relating to the project, but only if those costs were incurred prior to the current year.

e. Effects of the project on other divisions of the firm, but only if those effects lower the projects own direct cash flows.
