Dividend Payment Requirements: Common Stock vs. Preferred Stock Preferred Stock: Primary Claim: Preferred stockholders have a higher claim on dividend distributions than common stockholders. This means that dividends must be paid to preferred shareholders before any dividends can be distributed to common shareholders. Fixed Dividends: Preferred stock typically pays fixed dividends, which do not vary with the company’s earnings. These dividends are usually set at the time of issuance and are consistent over time. Cumulative Dividends: Many preferred stocks are cumulative, meaning if a company skips a dividend payment, it must pay the missed dividends to preferred shareholders before paying any dividends to common shareholders.
