Answer:
11.70%
Step-by-step explanation:
The computation of the cost of preferred stock is shown below :-
The cost of preferred stock = {Annual Dividend} ÷ {Price of preferred stock per share × (1 - Flotation cost)}
= {$9.35} ÷ {$85 × (1 - 0.06)}
= {$9.35} ÷ {$85 × 0.94}
= {$9.35} ÷ {$79.9}
= 11.70%
We ignored the marginal tax rate i.e. given in the question.
