6.1 Introduction • Components of capital structure • Opportunity cost, required rate-of-return, and the cost of capital

6.1 Introduction (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.

6.2 Bond valuation • Perpetuity • Term bonds • Preferred stock

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

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

6.2 Bond valuation TABLE 6.1 Convertible bond: conversion options 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.

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

6.3 Common-stock valuation • Valuation • Inflation and common-stock valuation • Growth opportunity and common-stock valuation

6.3 Common-stock valuation (6.6a) where P0 = Present value, or price, of the common stock per share, dt = Dividend payment, k = Required rate of return for the stock, assumed to be a constant term, Pn = Price of the stock in the period when sold.

6.3 Common-stock valuation (6.6b) (6.6c)

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

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

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

6.3 Common-stock valuation (6.8a) where The equation (6.8) is related to operating-income hypothesis which has been discussed in chapter 5 on pages 158-160.

6.3 Common-stock valuation (6.9) where = Current expected earnings per share, b = Investment (It) as a percentage of total earnings (Xt), r = Internal rate of return V0 and k = Current market value of a firm and the required rate of return, respectively.

6.3 Common-stock valuation (6.9a) (6.9b)

6.4 Financial leverage and its effect on EPS • 6.4.1 Measurement • 6.4.2 Effect

6.4 Financial leverage and its effect on EPS (6.10) where ke = Return on equity, r = Return on total assets (return on equity without leverage) i = Interest rate on outstanding debt, D = Outstanding debt, E = Book value of equity.

6.4 Financial leverage and its effect on EPS (6.11) (6.10a) (6.12a)

6.6 Possible Reason for Optimal Capital Structure • The traditional Approach of Optimal Capital Structure • Bankruptcy Cost • Agency Cost

Possibility of Optimal Debt Ratio when Bankruptcy Allowed

6.7 Summary 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.

Appendix 6A. Convertible security valuation theory (6.A.1) where P = Market value of the convertible bond, r = Coupon rate on the bond, F = Face value of the bond, P0 = Initial market value, ki = Effective rate of interest on the bond at the end of the period m (now), n = Original maturity of the bond, m = Number of periods since the bond was issued, j = Number of periods from the time the bond was issued till the time of conversion, F’= Value of the stock on date of conversion, t = Marginal corporate tax rate.
