Answer:
Dividends are fixed ⇒ Debt
Preferred dividends are fixed much like the interest payments made on debt which makes this a characteristic of debt.
Usually have no specified maturity date ⇒ Equity
Equity does not have an expiration or maturity date and preferred shares share this same characteristic.
Cost of preferred stock.
The value of a Preferred stock is calculated by the formula:
Price = Dividend / Cost of preferred stock
97.95 = 11 / Cp
97.95 * Cp = 11
Cp = 11/ 97.95
= 11.23%
