Payback, NPV, and MIRR

Your division is considering two investment projects, each of which requires an up-front expenditure of $22 million. You estimate that the cost of capital is 9% and that the investments will produce the following after-tax cash flows (in millions of dollars):

Year	Project A		Project B
1	5		20
2	10		10
3	15		8
4	20		6

1. What is the regular payback period for each of the projects? Round your answers to two decimal places.

   Project A: years

   Project B: years

2. What is the discounted payback period for each of the projects? Do not round intermediate calculations. Round your answers to two decimal places.

   Project A: years

   Project B: years

3. If the two projects are independent and the cost of capital is 9%, which project or projects should the firm undertake?

   The firm should undertake

4. If the two projects are mutually exclusive and the cost of capital is 5%, which project should the firm undertake?

   The firm should undertake

5. If the two projects are mutually exclusive and the cost of capital is 15%, which project should the firm undertake?

   The firm should undertake

6. What is the crossover rate? Round your answer to two decimal places.

   %

7. If the cost of capital is 9%, what is the modified IRR (MIRR) of each project? Do not round intermediate calculations. Round your answers to two decimal places.

   Project A: %

   Project B: %
