2. Compute BioCom's cost of preferred stock. Preferred Stock | | Price | 19 | Flotation | | Dividend | 1,5 | Par | 50 | | | Cost of Pref | 7,89% |

3. Compute BioCom's cost of common equity. Use the average of results from the dividend growth model and the security market line. Common stocks | | Dividend | 2,5 | Growth Rate | 6% | Price | 35 | Cost of equity | 13,57% |

Common stocks | | Market return | 12% | Risk Free | 3% | Beta | 1,2 | Cost of equity | 13,80% | Common stocks | | SML | 14% | Dividend Growth Model | 0,135714 | Average cost of equity | 13,69% |

4. Compute BioCom's weighted average cost of capital. Should you use book values or market values for this computation?

For calculating the WACC, I would use Book Values because for calculating on Market Rates we need to know quantity of common and preferred stock shares. Type of Capital | Percent of Book Value | Cost | | Bond 1 | 18% | 2,10% | 0,38% | Bond 2 | 20% | 2,53% | 0,51% | Pref | 20% | 7,89% | 1,58% | Com | 5% | 13,69% | 0,68% | Retained earnings | 37% | | 0,00% | Tot cost | | | 3,15%
