Company A wants to calculate its WACC. It has just issued a 17-year, 8% coupon, non-callable bond at par value. A's current stock price is $36 and A just paid s $0.5 per share dividend. A's dividend payment is expected to grow at a constant rate of 3% a year. A wants to keep a debt-to-capital ratio of 10%. Tax rate is 35%. If A does not have preferred stock and floatation costs, what is its WACC (please report WACC as a decimal number with four decimal places, such as 0.0562)?
