Chapter 9 The Cost of Capital LEARNING OBJECTIVES After reading this chapter, students should be able to: Explain what is meant by a firm’s weighted average cost of capital. Define and calculate the component costs of debt and preferred stock. Explain why retained earnings are not free and use three approaches to estimate the component cost of retained earnings. Briefly explain why the cost of new common equity is higher than the cost of retained earnings, calculate the cost of new common equity, and calculate the retained earnings breakpoint--which is the point where new common equity would have to be issued. Briefly explain the two alternative approaches that can be used to account for flotation costs. Calculate the firm’s composite, or weighted average, cost of capital. Identify some of the factors that affect the overall, composite cost of capital. Briefly explain how firms should evaluate projects with different risks, and the problems encountered when divisions within the same firm all use the firm’s composite WACC when considering capital budgeting projects. List and briefly explain the three separate and distinct types of risk that can be identified, and explain the procedure many firms use when developing subjective risk-adjusted costs of capital. List some problem areas in estimating the cost of capital. LECTURE SUGGESTIONS Chapter 9 uses the rate of return concepts covered in previous chapters, along with the concept of the weighted average cost of capital (WACC), to develop a corporate cost of capital for use in capital budgeting. We begin by describing the logic of the WACC, and why it should be used in capital budgeting. We next explain how to estimate the cost of each component of capital, and how to put the components together to determine the WACC. We go on to discuss factors that affect the WACC, how to adjust the cost of capital for risk, and estimating project risk. We conclude the chapter with a discussion on some problem areas in the cost o
