Compute the cost of each component of capital structure and WACC
1. P. Lange Inc. hired your consulting firm to help them estimate the cost of equity. The yield on Lange's bonds is 7.25%, and your firm\'s economists believe that the cost of equity can be estimated using a risk premium of 3.50% over a firm's own cost of debt. What is an estimate of Lange's cost of equity from retained earnings?
2. You were hired as a consultant to Kroncke Company, whose target capital structure is 40% debt, 10% preferred, and 50% common equity. The after-tax cost of debt is 6.00%, the cost of preferred is 7.50%, and the cost of retained earnings is 13.25%. The firm will not be issuing any new stock. What is its WACC?
