Shareholders' Equity: Shareholders' equity is the value of the assets remaining after deducting the company's total liabilities. It represents the net worth of the company and includes common stock, additional paid-in capital, and retained earnings.
Preferred Stock: Preferred stock is a type of equity security that gives the holder a claim on the company's earnings and assets that is superior to the claims of common stockholders. Preferred stockholders typically receive dividends before common stockholders and have a higher priority in the event of liquidation.
Weighted Average Cost of Capital (WACC): Weighted Average Cost of Capital (WACC) is a calculation of a firm's cost of capital in which each category of capital (common equity, preferred equity, and debt) is proportionately weighted. WACC is the average rate a company expects to pay to finance its assets.
