Southern Mining's outstanding debt has a before-tax cost of 8.5 percent and a current market value of $37.5 million. The market value of the firm's outstanding equity is $62.5 million. Given Southern's current financial/capital structure, the firm's cost of equity capital is 14.9 percent.

(b) the impact of the recapitalization on Southern's weighted average cost of capital
