6.1Introduction (6.1) where = Expected rate of return for asset j, = Return on a risk-free asset, = Market risk premium, or the difference in return on the market as a whole and the return on a risk-free asset, = Beta coefficient for the regression of an individual’s security return on the market return; the volatility of the individual security’s return relative to the market return. 4

6.2Bond valuation (6.2) where n = Number of periods to maturity, CF t = Cash flow (interest and principal) received in period t, k b = Required rate-of-return for bond. 6

6.2Bond valuation (6.3) (6.4) where I t = Coupon payment, coupon rate X face value, p = Principal amount (face value) of the bond, n = Number of periods to maturity. 7

6.2Bond valuation TABLE 6.1 Convertible bond: conversion options Advantages Purchase Price Of BondGain (1)Conversion to stock if price rises above $25. (2)Interest payment if stock price remains less than $25. (3)Interest payment versus stock dividend. $1000 Sell 40 shares at $30, = $1,200, for a return of 12%. $100 per year, for a return of 10% Dividend must rise to $2.50 per share before return on stock = 10%. 8 The results in this table are based on a $1000 face-value bond with 10% coupon rate, convertible to 40 shares of stock at $25 each.

6.2Bond valuation (6.5) where d p = Fixed dividend payment, coupon X par on face value of preferred stock; k p = Required rate-of-return on the preferred stock. 9

6.3Common-stock valuation (6.6a) where P 0 = Present value, or price, of the common stock per share, d t = Dividend payment, k = Required rate of return for the stock, assumed to be a constant term, P n = Price of the stock in the period when sold. 11

6.3Common-stock valuation (6.7) where g s = Growth rate of dividends during the super-growth period, n = Number of periods before super-growth declines to normal, g n = Normal growth rate of dividends after the end of the super-growth phase, r = Internal rate-of-return. 13

14
6.3Common-stock valuation where d t = Dividend payment per share in period t, p = Proportion of earnings paid out in dividends (the payout ratio, 0 p 1.0), EPS t = earnings per share in period t. 14

15
6.3Common-stock valuation (6.8) Where Q t = Quantity of product sold in period t, P t = Price of the product in period t, V t = Variable costs in period t, F = Depreciation and interest expenses in period t, = Firm tax rate. 15

6.7Summary and remarks In this chapter the basic concepts of valuation and capital structure are discussed in detail. First, the bond-valuation procedure is carefully discussed. Secondly, common-stock valuation is discussed in terms of (i) dividend-stream valuation and (ii) investment-opportunity valuation. It is shown that the first approach can be used to determine the value of a firm and estimate the cost of capital. The second method has decomposed the market value of a firm into two components, i.e., perpetual value and the value associated with growth opportunity. The criteria for undertaking the growth opportunity are also developed. An overall view on the optimal capital structure has been discussed in accordance with classical, new classical, and some modern finance theories. Modigliani and Miller’s Proposition I with and without tax has been reviewed in detail. It is argued that Proposition I indicates that a firm should use either no debt or 100 percent debt. In other words, there exists no optimal capital structure for a firm. However, both classical and some of the modern theories demonstrate that there exists an optimal capital structure for a firm. In summary, the results of valuation and optimal capital structure will be useful for financial planning and forecasting. 42
