Firms HL and LL are identical except for their financial leverage ratios and the interest rates they pay on debt. Each has $27 million in invested capital, has $4.05 million of EBIT, and is in the 25% federal-plus-state tax bracket. Firm HL, however, has a debt-to-capital ratio of 45% and pays 11% interest on its debt, whereas LL has a 20% debt-to-capital ratio and pays only 9% interest on its debt. Neither firm uses preferred stock in its capital structure.
