QUESTION TWO (a). Construct a theoretical proof of the following for a firm with no supernormal growth (in a world with only corporate taxes): E (EBIT) (1 - Tc) VL = VU + TcB = WACC Where VL = the value of a levered firm TC = corporate tax rate VU = the value of an unlevered firm EBIT = earnings before interest and tax WACC = weighted average cost of capital (b). The standard case of the Modigliani-Miller theorem on capital structure assumes that the firm has only two classes of securities, namely perpetual debt and equity. Suppose that the firm has issued preferred stock as a third class of securities, and that X% of preferred dividends may be written off as expense (0 x 1), derive the appropriate expression for: (i). the value of the levered firm; (ii). The weighted average cost of capital. = QUESTION TWO (a).
