How do dividends and retained earnings affect equity financing?

"Dividends are payments to stockholders from a corporation’s profits. Dividends can be paid in cash or in stock. Stock dividends are payments in the form of more stock. Stock dividends may replace or supplement cash dividends. After a stock dividend has been paid, more shares have a claim on the same company, so the value of each share often declines. A company does not have to pay dividends to stockholders. But if investors buy the stock expecting to get dividends and the firm does not pay them, the investors may sell their stocks. At their quarterly meetings, the company’s board of directors (typically with the advice of its CFO) decides how much of the profits to distribute as dividends and how much to reinvest. A firm’s basic approach to paying dividends can greatly affect its share price. A stable history of dividend payments indicates good financial health. For example, cable giant Comcast has increased its dividend more than 20 percent over the past five years, giving shareholders a healthy return on their investment. If a firm that has been making regular dividend payments cuts or skips a dividend, investors start thinking it has serious financial problems. The increased uncertainty often results in lower stock prices. Thus, most firms set dividends at a level they can keep paying. They start with a relatively low dividend payout ratio so that they can maintain a steady or slightly increasing dividend over time. Retained earnings, profits that have been reinvested in the firm, have a big advantage over other sources of equity capital: They do not incur underwriting costs. Financial managers strive to balance dividends and retained earnings to maximize the value of the firm. Often the balance reflects the nature of the firm and its industry. Well-established and stable firms and those that expect only modest growth, such as public utilities, financial services companies, and large industrial corporations, typically pay out much of their earnings in dividends. Most high-growth companies, such as those in technology-related fields, finance much of their growth through retained earnings and pay little or no dividends to stockholders. As they mature, many decide to begin paying dividends."
