This document discusses dividend theory and policy. It explains that in the absence of dividends, corporate earnings accrue to shareholders as retained earnings that are automatically reinvested in the firm. However, when dividends are declared, those funds leave the firm permanently. The document then outlines several factors that determine a firm's dividend policy, including dividend payout ratio, stability of dividends, legal restrictions, and owners' considerations. It provides examples and explanations of different types of dividend payments, including cash dividends, stock dividends, stock splits, and share repurchases.
