ABC is now considering changing the debt ratio and moving it to the new debt/assets ratio as indicated below, and replacing all preferred stocks with debt. The money raised would be used to repurchase preferred stock at the current price. It is estimated that the increase in risk resulting from the additional leverage would cause the required rate of return on equity to rise somewhat, as indicated below. If this plan were carried out, (a) By how much would the WACC change, 1.e., what is wassaiah - Wassen (WACC (in question (1) or (2)) - WACC (in question (3)) ? New Debt/Assets 650 Interest rate new = 4 6.08 New Equity/Assets 358 New cost of equity for 13.08 (b) Based on the Hamada equation, what would the firm's beta be if it used no debt, 1.e., what is its unlevered beta? ABC Inc.'s capital structure is 40% debt, 25% preferred, and 35% common equity, and its tax rate is 35%.

(b) ABC sold a perpetual preferred stock for $95.50 per share, with a $7.50 annual dividend and a flotation cost of 3.000 of the price.
