Within-firm (corporate) risk refers to the projects effect on the stability of the firms earnings. Stand-alone risk Answers and Solutions: 9 - 1ANSWERS TO END-OF-CHAPTER QUESTIONS: Chapter 9refers to the inherent riskiness of the projects expected returns when viewed alone. Theoretically, beta (market) risk is the most relevant measure because of its effect on stock prices.9-3The cost of capital for average-risk projects would be the firms cost of capital, 10 percent. A somewhat higher cost would be used for more risky projects, and a lower cost would be used for less risky ones. For example, we might use 12 percent for more risky projects and 9 percent for less risky projects. These choices are arbitrary.9-4Each firm has an optimal capital structure, defined as that mix of debt, preferred, and common equity that causes its stock price to be maximized. A value-maximizing firm will determine its optimal capital structure, use it as a target, and then raise new capital in a manner designed to keep the actual capital structure on target over time. The target proportions of debt, preferred stock, and common equity, along with the costs of those components, are used to calculate the firms weighted average cost of capital, WACC.The weights could be based either on the accounting values shown on the firms balance sheet (book values) or on the market values of the different securities. Theoretically, the weights should be based on market values, but if a firms book value weights are reasonably close to its market value weights, book value weights can be used as a proxy for market value weights. Consequently, target market value weights should be used in the WACC equation.9-5An increase in the risk-free rate will increase the cost of debt. Remember from Chapter 4, k = kRF+ DRP + LP + MRP. Thus, if kRF increases so does k (the cost of debt). Similarly, if the risk-free rate increases so does the cost of equity. From the CAPM equation, ks= kRF+ (kM kRF)b. Consequently, if kRFincreases kswill increase too....
