Answer: 11.978%
Step-by-step explanation:
From the question, we are informed that the 10.9 percent preferred stock of Rock Bottom Floors is selling for $91 a share. We are further informed that the tax rate is 44 percent and the par value per share is $100.
The firm's cost of preferred stock will be 10.9% multiplied by the par value per share and then divided by the share price of $91. This will be:
= (10.9% × 100)/91
= (0.109 × 100)/91
= 10.9/91
= 0.11978
= 11.978%
