May I kindly ask about calculation WACC and explain a little bit that I would like to understand how. It has current capital and new capital determine.

The comic book publishing group (CBPG) has a capital structure of $ 12 million in bonds, paying a 5% coupon, $ 5 million in preferred stock, a face value of $ 35 per share and an annual dividend of $ 1.75 per share. The company's common stock has a book value of $ 6 million. 10% common stock and the company's marginal tax rate is 33%.

The company wants to add another $ 10 million by public debt offering (corporate bond) but bonds at a coupon rate of 4% due to favorable interest rates.
