1. Clear Display Corp. (CDC) is considering two mutually exclusive investment projects. The cost of capital for these projects is r. The projects' expected net cash flows are as follows: Year Project M's expected cash flow Project N's expected cash flow 0 -42,000 -42,000 1 24,000 14,000 2 20,000 18,000 3 16,000 22,000 4 12,000 26,000 a. r = 10%. Calculate each project's payback period (up to 2 decimal places). Which project should be accepted? b.r-10%. Calculate cach project's discounted payback period (up to 2 decimal places). Which project should be accepted? c. Construct NPV profiles (Y axis = NPV; X axis = r; two curves in one chart) for Projects M and N, using r = 0%, 4%, 8%, 10%, 12%, 16%, 20%, 22%, 24%, 28%, 32%, 36%, and 40%. Show calculations and an Excel chart. What is the approximate crossover rate from the chart? Hint: Can use an Excel function to save time. d. Calculate each project's IRR. Show the IRR expression or equation. If r - 10%, which project should be accepted under the IRR method? e. Ifr=10%, which project should be selected? Ifr= 24%, which project should be selected? f. Calculate each project's PI at r = 10% and r = 24%, respectively. Under the PI method, which project should be selected
