Why is it not a requirement for companies to pay dividends?
The shareholders have a claim on the profits, but they may prefer that claim to be exercised in ways other than dividend payments. For example, they may want the company to invest all of its profits in growth, or they may want it to buy back shares to increase the value of the remaining shares, especially since dividends are generally taxed as income while an increase in the share price is generally taxed as a capital gain, and capital gains are often taxed at a lower rate than income. Cash flow is needed for expansion, either to increase manufacturing capacity or to expand the workforce. Other times companies use it to purchase other companies. Microsoft and Google have both used their cash or stocks to purchase companies. Examples by Google include YouTube, Keyhole (Google Earth), and now part of Motorola to expand into Phones. If you are investing for the future, you don't want a lot of dividends. They do bring tax issues. That is not a big problem if you are investing in an IRA or 401K. It is an issue if the non-tax-defered mutual fund distributes those dividends via the 1099, forcing you to address it on your taxes each year. Some investors do like dividends, but they are looking for their investments to generate cash. Who would require it? Would it be an SEC requirement? Even more government paperwork for companies. "This answer will expand a bit on the theory. :) A company, as an entity, represents a pile of value. Some of that is business value (the revenue stream from their products) and some of that is assets (real estate, manufacturing equipment, a patent portfolio, etc). One of those assets is cash. If you own a share in the company, you own a share of all those assets, including the cash. In a theoretical sense, it doesn't really matter whether the company holds the cash instead of you. If the company adds an extra $1 billion to its assets, then people who buy and sell the company will think ""hey, there's an extra $1 billion of cash in that company; I should be willing to pay $1 billion / shares outstanding more per share to own it than I would otherwise."" Granted, you may ultimately want to turn your ownership into cash, but you can do that by selling your shares to someone else. From a practical standpoint, though, the company doesn't benefit from holding that cash for a long time. Cash doesn't do much except sit in bank accounts and earn pathetically small amounts of interest, and if you wanted pathetic amounts of interests from your cash you wouldn't be owning shares in a company, you'd have it in a bank account yourself. Really, the company should do something with their cash. Usually that means investing it in their own business, to grow and expand that business, or to enhance profitability. Sometimes they may also purchase other companies, if they think they can turn a profit from the purchase. Sometimes there aren't a lot of good options for what to do with that money. In that case, the company should say, ""I can't effectively use this money in a way which will grow my business. You should go and invest it yourself, in whatever sort of business you think makes sense."" That's when they pay a dividend. You'll see that a lot of the really big global companies are the ones paying dividends - places like Coca-Cola or Exxon-Mobil or what-have-you. They just can't put all their cash to good use, even after their growth plans. Many people who get dividends will invest them in the stock market again - possibly purchasing shares of the same company from someone else, or possibly purchasing shares of another company. It doesn't usually make a lot of sense for the company to invest in the stock market themselves, though. Investment expertise isn't really something most companies are known for, and because a company has multiple owners they may have differing investment needs and risk tolerance. For instance, if I had a bunch of money from the stock market I'd put it in some sort of growth stock because I'm twenty-something with a lot of savings and years to go before retirement. If I were close to retirement, though, I would want it in a more stable stock, or even in bonds. If I were retired I might even spend it directly. So the company should let all its owners choose, unless they have a good business reason not to. Sometimes companies will do share buy-backs instead of dividends, which pays money to people selling the company stock. The remaining owners benefit by reducing the number of shares outstanding, so they own more of what's left. They should only do this if they think the stock is at a fair price, or below a fair price, for the company: otherwise the remaining owners are essentially giving away cash. (This actually happens distressingly often.) On the other hand, if the company's stock is depressed but it subsequently does better than the rest of the market, then it is a very good investment. The one nice thing about share buy-backs in general is that they don't have any immediate tax implications for the company's owners: they simply own a stock which is now more valuable, and can sell it (and pay taxes on that sale) whenever they choose." You have plenty of good answers, but I want to add something that might help you grow your intuition on stocks. There are a lot of differences between the example I am going to give and how the stock market actually runs, but the basic concepts are the same. Lets say your friend asks you if he can borrow some money to start up a company, in exchange you will have some ownership in this company. You have essentially just bought yourself some stock. Now as your friend starts to grow, he is doing well, but he needs more cash to buy assets in order to grow the company more. He is forced with an option, either give you some of the profits, or buy these assets sooner. You decide you don't really need the money right now, and think he can do a lot better with spending the money to buy stuff. This is essentially the same as a company electing to not pay dividends, but instead invest into the future. You as a stock holder are fine with it since you know the money is going toward investing in the future. Even if you never get paid a dividend, as a company grows, you can then turn around and sell the stock to someone else for more money then you gave originally. Of course you always take the risk of having the company failing and loosing some if not all of your investment, but that is just the risk of the market.
"There are many different methods for a corporation to get money, but they mostly fall into three categories: earnings, debt and equity.  Earnings would be just the corporation's accumulation of cash due to the operation of its business. Perhaps if cash was needed for a particular reason immediately, a business may consider selling a division or group of assets to another party, and using the proceeds for a different part of the business. Debt is money that (to put it simply) the corporation legally must repay to the lender, likely with periodic interest payments. Apart from the interest payments (if any) and the principal (original amount leant), the lender has no additional rights to the value of the company. There are, basically, 2 types of corporate debt: bank debt, and bonds.  Bank debt is just the corporation taking on a loan from a bank. Bonds are offered to the public - ie: you could potentially buy a ""Tesla Bond"", where you give Tesla $1k, and they give you a stated interest rate over time, and principal repayments according to a schedule. Which type of debt a corporation uses will depend mostly on the high cost of offering a public bond, the relationships with current banks, and the interest rates the corporation thinks it can get from either method. Equity [or, shares] is money that the corporation (to put it simply) likely does not have a legal obligation to repay, until the corporation is liquidated (sold at the end of its life) and all debt has already been repaid. But when the corporation is liquidated, the shareholders have a legal right to the entire value of the company, after those debts have been paid. So equity holders have higher risk than debt holders, but they also can share in higher reward. That is why stock prices are so volatile - the value of each share fluctuates based on the perceived value of the entire company.  Some equity may be offered with specific rules about dividend payments - maybe they are required [a 'preferred' share likely has a stated dividend rate almost like a bond, but also likely has a limited value it can ever receive back from the corporation], maybe they are at the discretion of the board of directors, maybe they will never happen. There are 2 broad ways for a corporation to get money from equity: a private offering, or a public offering. A private offering could be a small mom and pop store asking their neighbors to invest 5k so they can repair their business's roof, or it could be an 'Angel Investor' [think Shark Tank] contributing significant value and maybe even taking control of the company. Perhaps shares would be offered to all current shareholders first. A public offering would be one where shares would be offered up to the public on the stock exchange, so that anyone could subscribe to them. Why a corporation would use any of these different methods depends on the price it feels it could get from them, and also perhaps whether there are benefits to having different shareholders involved in the business [ie: an Angel investor would likely be involved in the business to protect his/her investment, and that leadership may be what the corporation actually needs, as much or more than money]. Whether a corporation chooses to gain cash from earnings, debt, or equity depends on many factors, including but not limited to: (1) what assets / earnings potential it currently has; (2) the cost of acquiring the cash [ie: the high cost of undergoing a public offering vs the lower cost of increasing a bank loan]; and (3) the ongoing costs of that cash to both the corporation and ultimately the other shareholders - ie: a 3% interest rate on debt vs a 6% dividend rate on preferred shares vs a 5% dividend rate on common shares [which would also share in the net value of the company with the other current shareholders].  In summary: Earnings would be generally preferred, but if the company needs cash immediately, that may not be suitable. Debt is generally cheap to acquire and interest rates are generally lower than required dividend rates. Equity is often expensive to acquire and maintain [either through dividend payments or by reduction of net value attributable to other current shareholders], but may be required if a new venture is risky. ie: a bank/bondholder may not want to lend money for a new tech idea because it is too risky to just get interest from - they want access to the potential earnings as well, through equity." Dividends are normally paid in cash, so don't generally affect your portfolio aside from a slight increase to 'cash'.  You get a check for them, or your broker would deposit the funds into a money-market account for you.  There is sometimes an option to re-invest dividends, See Westyfresh's answer regarding Dividend Re-Investment Plans. As Tom Au described, the dividends are set by the board of directors and announced.  Also as he indicated just before the 'record' date, a stock which pays dividends is worth slightly more (reflecting the value of the dividend that will be paid to anyone holding the stock on the record date) and goes down by the dividend amount immediately after that date (since you'd now have to hold the stock till the next record date to get a dividend)  In general unless there's a big change in the landscape (such as in late 2008) most companies pay out about the same dividend each time, and changes to this are sometimes seen by some as 'indicators' of company health and such news can result in movement in the stock price. When you look at a basic quote on a ticker symbol there is usually a line for Div/yeild which gives the amount of dividend paid per share, and the relative yeild (as a percentage of the stock price).  If a company has been paying dividends, this field will have values in it, if a company does not pay a dividend it will be blank or say NA (depending on where you get the quote).  This is the easiest way to see if a company pays a dividend or not.  for example if you look at this quote for Google, you can see it pays no dividend  Now, in terms of telling when and how much of a dividend has been paid, most financial sites have the option when viewing a stock chart to show the dividend payments.  If you expand the chart to show at least a year, you can see when and how much was paid in terms of dividends.  For example you can see from this chart that MSFT pays dividends once a quarter, and used to pay out 13 cents, but recently changed to 16 cents.   if you were to float your mouse over one of those icons it would also give the date the dividend was paid. You should never invest in a stock just for the dividend. Dividends are not guaranteed. I have seen some companies that are paying close to 10% dividends but are losing money and have to borrow funds just to maintain the dividends. How long can these companies continue paying dividends at this rate or at all. Would you keep investing in a stock paying 10% dividends per year where the share price is falling 20% per year? I know I wouldn't. Some high dividend paying stocks also tend to grow a lot slower than lower or non dividend paying stocks. You should look at the total return - both dividend yield and capital return combined to make a better decision. You should also never stay in a stock which is falling drastically just because it pays a dividend. I would never stay in a stock that falls 20%, 30%, 50% or more just because I am getting a 5% dividend. Regarding taxation, some countries may have special taxation rules when it comes to dividends just like they may have special taxation rules for longer term capital gains compared to shorter term capital gains. Again no one should use taxation as the main purpose to make an investment decision. You should factor taxation into your decision but it should never be the determining factor of your decisions. No one has ever become poor in making a gain and paying some tax, but many people have lost a great portion of their capital by not selling a stock when it has lost 50% or more of its value. When you buy shares, you are literally buying a share of the company.  You become a part-owner of it. Companies are not required to pay dividends in any given year.  It's up to them to decide each year how much to pay out. The value of the shares goes up and down depending on how much the markets consider the company is worth.  If the company is successful, the price of the shares goes up.  If it's unsuccessful, the price goes down.  You have no control over that.  If the company fails completely and goes bankrupt, then the shares are worthless. Dilution is where the company decides to sell more shares.  If they are being sold at market value, then you haven't really lost anything.  But if they are sold below cost (perhaps as an incentive to certain staff), then the value of the company per share is now less.  So your shares may be worth a bit less than they were.  You would get to vote at the AGM on such schemes.  But unless you own a significant proportion of the shares in the company, your vote will probably make no difference. In practice, you can't protect yourself.  Buying shares is a gamble.  All you can do is decide what to gamble on. Why? Balance sheet is balance sheet, why is it complicated? Bank shareholders get dividends in exactly the same way as any other company shareholders do: the company ends up with net profits, which the board of directors decides to distribute to shareholders based on certain amount per share. If at all. Not all the profits are distributed, and in fact - there are companies who don't distribute dividends at all. Apple, for example, hasn't ever distributed dividends until very very recently. A stock dividend converts some of the reserves and surplus on the company's balance sheet into paid-up capital and securities premium account without involving any actual cash outflow to the shareholders. While cash dividends are eyed by the investors due to their cash yield, issuance of stock dividends are indicators of growing confidence of the management and the shareholders in the company.  The fact that shareholders want to convert free cash sitting on the balance sheet (which can ideally be taken out as dividends) into blocked money in exchange for shares is symbolic to their confidence in the company. This in turn is expected to lead to an increase in market price of the stock. Shareholders can [often] vote for management to pay dividends Shareholders are sticking around if they feel the company will be more valuable in the future, and if the company is a target for being bought out. Greater fool theory You only have to own it for a day (or rather for some amount of time before the close of trading the day before the ex-dividend date).  This is governed by exchange rules based on the date of record and payable date set by the company.  You might want to look at this article or this one for more details. It should be difficult to make money from changes due to the dividend distribution since it is well known and expected.  The exchanges have established rules for handling the various details that can come up, and traders account for the change where appropriate (as in option pricing).  Also, note that the favorable U.S. tax treatment of dividends requires a 60-day ownership period for the stock.
