Duffy was just hired as CEO of Dog Food Inc. (DFI), which has no debt on its balance sheet. He also forecasts that the firm is expected to pay $200 million/year in taxes and is expected to have a constant 20% tax rate. Assuming no bankruptcy costs, but personal taxes of 30% on income from equity and 50% on income from interest, if Duffy were to issue $75 million in perpetual debt at 8%, what is the present value of the tax shield? -$8 mil -$9 mil -$15 mil -$12 mil - $14 mil
