Calculate the NPV for a 3-year project with the following cash flows and a required return of 15%: CF0 = -$800,000 ATCF1 = $160,000 ATCF2 = $160,000 ATCF3 = $160,000 ATER = $600,000

Calculate the IRR for a 2-year project with the following cash flows and a required return of 12%: CFO = -$375,000 ATCF1 = $27,500 ATCF2 = -$134,800 ATER = $596,000

ATER = After-Tax Equity Reversion

ATCF = After-Tac Cash Flow
