Turnbull Co. has a target capital structure of 58% debt, 6% preferred stock, and 36% common equity. It has a before-tax cost of debt of 11.1%, and its cost of preferred stock is 12.2%.

If Turnbull can raise all of its equity capital from retained earnings, its cost of common equity will be 14.7%. However, if it is necessary to raise new common equity, it will carry a cost of 16.8%.

If its current tax rate is 25%, how much higher will Turnbulls weighted average cost of capital (WACC) be if it has to raise additional common equity capital by issuing new common stock instead of raising the funds through retained earnings? (Note: Round your intermediate calculations to two decimal places.)
