Currently, Mil & Mod is an all-equity firm and expects EBIT to be around $151.52 million per year in perpetuity. The company currently pays a marginal tax rate of 34% and the unlevered cost of capital is 20%. Dougherty is trying to calculate the impact of a $500 million increase in debt, which can be obtained at an interest rate of 10%.
