Grey Fox Aviation Company is evaluating a proposed capital budgeting project (project Sigma) that will require an initial investment of $750,000. Grey Fox Aviation Company has been basing capital budgeting decisions on a project's NPV; however, its new CFO wants to start using the IRR method for capital budgeting decisions. The CFO says that the IRR is a better method because returns in percentage form are easier to understand and compare to required returns. Grey Fox Aviation Company's WACC is 10%, and project Sigma has the same risk as the firm's average project. The project is expected to generate the following net cash flows: Which of the following is the correct calculation of project Sigma's IRR? Year Cash Flo Year 1 $325,000 Year 2 $450,000 Year 3 $400,000 Year 4 $475,000 ? 30.73% 0 34.57% ? 38.41% o 36.49%
