A-3 (Coverage ratio) The firm in the two preceding problems also had $6 million of principal repayments during the latest 12 months. Its marginal tax rate is 40%. Calculate the debt service coverage ratio. Debt-Service Coverage Ratio = (EBIT + 1/3 Rentals) / (Interest Expense + 1/3 Rentals + Principal Repayments / (1 - T)) = ($30 + $15 / 3) / ($10 + $15 / 3 + $6 / (1 - 0.40)) = 1.40 A-4 (WACC with rebalancing) Nathan’s Catering is a gourmet catering service located in Southampton‚ New York
