In its cost-of-capital computations, Gao uses the target capital structure with 45% debt, 5% favoured stock, and 50% common equity

i) Compute cost of each capital component, like, after-tax cost of debt, cost of preferred stock, cost of equity (ignoring flotation costs) with DCF method and CAPM method.

ii) Compute cost of new stock by using DCF model.

iii) Determine the cost of new common stock, based on CAPM? Determine the difference between ke and ks as determined by the DCF method, and add that differential to CAPM value for ks.

iv) By using target capital structure for Gao Computer and suppose that it will not issue new equity, will continue to use similar capital structure, determine the WACC?
