Consider the case of a firm with secured debt, subordinated debentures, and common stock, where the secured debt and subordinated debentures mature at the same time. Find the equations for the values of the three classes of securities using the OPM framework.
Assume no dividends or interest payments prior to the debts maturity and a lognormal distribution of the future value of the firms assets, 17"„ as shown in Fig. Q8.9, where V = market value of the firm, S = market value of the stock, Bs = market value of the senior debt, Bi = market value of the junior debt, Ds = face value of the senior debt, Di = face value of the junior debt.
