Sun Products Company (SPC) uses only debt and equity. It can issue bonds at an after-flotation interest rate of 12 percent so long as it finances at its target capital structure, which calls for 45 percent debt and 55 percent common equity. Its last dividend was $2.40, its expected constant growth rate is 5 percent, and its stock sells for $24. A flotation cost of 7% would be required to issue new common stock. SPCs tax rate is 40 percent. The company expects to earn $200 million in after-tax income during the coming year and will retain 70% of those earnings.

Four projects are available: Project A has a cost of $140 million and an IRR of 13 percent, Project B has a cost of $125 million and an IRR of 12 percent, Project C has a cost of $20 million and an IRR of 11 percent, and Project D has a cost of $50 million and an IRR of 10 percent. All of the companys potential projects are independent and equally risky.
