Answer:
$10.42%
Explanation:
The company's cost of preferred stock for use in calculating the WACC can be derived using the dividend valuation model because it is same as calculating the cost of equity with slight modification.
Dividend valuation model: Kp = Do / Po (ex dividend)
where:
Kp = Cost of Preference shares
Do = current dividend
Po = Price of shares
Note that the flotation cost has to be adjusted against the price of the shares
Hence Kp = $8.5 / $85 (100% - 4%) = 0.104166
Hence, The company's cost of preferred stock for use in calculating the WACC is 10.42%
