Your division is considering two investment projects, each of which requires an up-front expenditure of $28 million. You estimate that the cost of capital is 8% 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

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

   %

2. If the cost of capital is 8%, what is the modified IRR (MIRR) of each project? Do not round intermediate calculations. Round your answers to two decimal places.
