Dividends Share Repurchases

Section: Dividends and Share Repurchases Estimated study time: 60 minutes Content: Dividend and share repurchase policy decisions address how firms distribute value to shareholders. The Modigliani-Miller dividend irrelevance theorem holds that in perfect capital markets (no taxes, no transaction costs, no information asymmetry), dividend policy is irrelevant — investors can create "homemade dividends" by selling shares if they want cash, or reinvesting dividends if they don't, leaving total wealth unchanged. Real-world market imperfections break this irrelevance result and create genuine trade-offs. The key imperfections are: differential taxation of dividends versus capital gains, signaling effects (dividends convey management's private information about future earnings), clientele effects (different investor types prefer different dividend policies), and agency cost reduction (dividends force firms to access external capital markets, subjecting management to external discipline). Dividend policy mechanics include four types: regular cash dividends (most common; create a dividend clientele expectation), special dividends (one-time payments for exceptional cash events), liquidating dividends (return of capital), and stock dividends (additional shares). The key dates in the dividend process are: (1) Declaration date — board declares the dividend; (2) Ex-dividend date — the first date on which new buyers are not entitled to the declared dividend (stock price typically falls by approximately the dividend amount on this date, adjusted for taxes); (3) Record date — company identifies shareholders eligible to receive the dividend; and (4) Payment date — dividend is paid. In a frictionless world, the stock price should drop by exactly the dividend amount on the ex-date; in practice it drops by less due to differential taxation of dividends vs. capital gains. Share repurchases are an alternative method of returning capital. In a buyback, the company purchases its…
