Corporate Finance (VII): Dividend Policy / Cash Distribution Policy

Miller-Rock (1985) Model This model incorporates all the typical features of a signaling model: firms differ in their current cash flows; information asymmetry exists between managers and shareholders; firms wish for their true value to be reflected in the current stock price, as managerial incentive schemes trade off current market value against future profitability; the signal is the current dividend payment; the signal is costly because firms face diminishing marginal returns on investment opportunities and limited access to external financing—paying dividends entails sacrificing investment opportunities. For "good" firms, the cost of dividends is lower, since, given a fixed dividend level, the higher the current cash flow, the smaller the sacrifice. The model also incorporates taxation (dividend tax rate = ) and shareholders’ liquidity needs . Under perfect information, the optimal dividend is zero. Under asymmetric information, a separating equilibrium can be derived, yielding a value–dividend function and a dividend policy function . The model’s main conclusions are: (i) good firms announce higher dividends; (ii) dividend announcements contain information about future cash flows; (iii) the higher the announced dividend, the higher the market value (and vice versa); (iv) equilibrium dividend levels rise when adverse selection becomes more severe, dividend tax treatment improves, or shareholders’ liquidity needs increase. The slope of the value–dividend function becomes steeper as increases—that is, for a given magnitude of dividend change, the higher the tax rate, the larger the price reaction. If , the signaling effect vanishes. Dividends are a less efficient signal than share repurchases. This model faces several problems: ・ Why dividends? Since the model ignores taxes, it does not explicitly distinguish between dividends and share repurchases. It is, in fact, a theory about the signaling role of cash payouts—not specifically about dividends. ・ The manager’s objective function is ad hoc: why should managers care about market value? ・ The model does not explicitly explain why external funding is costly—or why external funding is unavailable. Some unmodeled reasons that could address these issues include: ・ Myers-Majluf-type problems. ・ Potential takeovers. ・ Risk of managerial dismissal. ・ Shareholders’ liquidity needs. A Tax-Based Signaling Model Three dates: investors are risk-neutral; the risk-free rate is zero. A continuum of firms, all equity-financed and holding no cash at , is characterized by existing assets that generate at : At , firms may: The underlying motivation is that capital gains are taxed only upon realization—that is, when shares are sold—allowing investors to defer tax payments into the future; moreover, capital gains tax rates are typically lower than dividend tax rates, making wealth accumulation via share-price appreciation tax-advantaged relative to receiving dividends. Initial shareholders face liquidity needs at and hold shares as their sole asset. They must sell a fraction of their shares to obtain at . Perfect Information: Shareholders of type- firms choose such that: Asymmetric Information: Initial shareholders know , but others do not. Assume a credible dividend announcement can be made at , with dividends paid at .

Dividends, Ex-Dividend Date, and High Dividend Yields

If you hold the stock at market close on this day, you are entitled to the upcoming dividend. Suppose August 10 is the record date. If you hold 100 shares at market close on that day, and the dividend is ¥1 per share, you will receive ¥100. Selling the stock the next day does not affect your entitlement to this dividend. Ex-Dividend Date Typically the trading day immediately following the record date. If the stock closed at ¥10 the day before, and the dividend is ¥1 per share, the ex-dividend reference price becomes approximately: ¥10 − ¥1 = ¥9. From this day onward, new buyers are no longer eligible for this round of dividends. Thus, buying the stock before the record date, collecting the dividend, and selling the next day does not yield a risk-free profit. The stock has already gone ex-dividend. Cash Dividend Payment Date On the payment date, the dividend is directly credited to your securities trading account. Suppose your account originally held ¥30,000 in cash; after receiving ¥100 in dividends, your cash balance becomes ¥30,100. Meanwhile, the stock has already been adjusted for the dividend. These three dates are straightforward: Record Date: determines who is eligible for the dividend. Ex-Dividend Date: the stock price is reduced by the value of the distributed dividend. Payment Date: cash is deposited into your account. What happens to the stock price after going ex-dividend is a separate matter. It may rebound from ¥9 back to ¥10—or fall further to ¥8. Recovering to the pre-ex-dividend price is commonly called “filling the dividend gap” (“filling the dividend”). But such a rebound is not part of the dividend itself, nor does it automatically occur simply because the company pays a dividend. So why do some investors still favor high-dividend stocks? Because dividends themselves do not create wealth—yet that does not mean dividends lack significance. The key distinction lies in whether the company can sustainably reinvest and earn returns on the distributed funds. One company earns ¥1 billion this year and distributes ¥500 million, then continues earning ¥1 billion—or even more—next year, and repeats the distribution. Another company holds only ¥10 billion in assets and distributes ¥500 million annually, yet its core business fails to generate sufficient ongoing profits. Both companies may display a 5% dividend yield—but their underlying fundamentals differ substantially. Thus, examining dividend yield alone offers little insight into a company’s quality. Firms like China Yangtze Power—whose mature assets reliably generate stable cash flows while requiring minimal reinvestment—naturally distribute dividends. By contrast, a rapidly growing firm with numerous high-return internal projects requiring substantial capital may not maximize value by distributing large profits. Whether cash remains within the firm or is distributed to shareholders ultimately depends on where that capital is deployed more efficiently. What is the difference between receiving a dividend and selling a portion of your shares yourself? In terms of final asset composition, the two actions are quite similar. Suppose you hold ¥100 worth of stock and need ¥5 in cash. If the company pays a ¥5 dividend: you end up with ¥95 in stock + ¥5 in cash.
