A firm has determined its target capital structure as having 31 % of its assets financed with debt and the remaining with equity. However, the debt is split evenly between a bank term loan bearing an interest cost of 9.9% and bonds that have a yield to maturity of 11 %. If shareholders in the firm demand a 16.8% return on their investment and the tax rate is 30% what is the firm's cost of capital? (The allowed rounding error for this question is within 0.1 %. Please type your answer in decimals. For example 9.8% should be shown as 0.098)
