What happens to internal stock when a company goes public?
You'd likely be subject to a lock-up period before you could sell the shares along with possibly having other rules about how you could sell your shares as you'd likely be seen as an insider that may have information that gives you an unfair advantage for selling the stock possibly. Depending on how far in advance you hold the shares, you may or may not have adjustments in the valuation and number of shares as some companies may do a split or reverse split when preparing for an IPO. A company I worked for in the late 1990s had an IPO and my stock options had a revised strike price because of a reverse stock split that was done prior to the IPO.
"You will have to check SEC forms to know this in full. A publicly-traded company will have an amount of publicly tradable shares which can be easily found on their financial reports. But. that is not the only type of equity-like financial instrument that such a company can issue. A previous reply mentions ""follow-on"" public offering. However, a company may initiate a private equity offering without disclosing ahead of time, sometimes with warrants, or long-lasting options to purchase (new) stock." "I think it's easiest to illustrate it with an example... if you've already read any of the definitions out there, then you know what it means, but just don't understand what it means.  So, we have an ice cream shop. We started it as partners, and now you and I each own 50% of the company. It's doing so well that we decide to take it public.  That means that we will be giving up some of our ownership in return for a chance to own a smaller portion of a bigger thing. With the money that we raise from selling stocks, we're going to open up two more stores.  So, without getting into too much of the nitty gritty accounting that would turn this into a valuation question, let's say we are going to put 30% of the company up for sale with these stocks, leaving you and me with 35% each. We file with the SEC saying we're splitting up the company ownership with 100,000 shares, and so you and I each have 35,000 shares and we sell 30,000 to investors.  Then, and this depends on the state in the US where you're registering your publicly traded corporation, those shares must be assigned a par value that a shareholder can redeem the shares at. Many corporations will use $1 or 10 cents or something nominal.  And we go and find investors who will actually pay us $5 per share for our ice cream shop business. We receive $150,000 in new capital. But when we record that in our accounting, $5 in total capital per share was contributed by investors to the business and is recorded as shareholder's equity. $1 per share (totalling $30,000) goes towards actual shares outstanding, and $4 per share (totalling $120,000) goes towards capital surplus.  These amounts will not change unless we issue new stocks. The share prices on the open market can fluctuate, but we rarely would adjust these. Edit: I couldn't see the table before. DumbCoder has already pointed out the equation Capital Surplus = [(Stock Par Value) + (Premium Per Share)] * (Number of Shares) Based on my example, it's easy to deduce what happened in the case you've given in the table. In 2009 your company XYZ had outstanding Common Stock issued for $4,652. That's probably (a) in thousands, and (b) at a par value of $1 per share. On those assumptions we can say that the company has 4,652,000 shares outstanding for Year End 2009.  Then, if we guess that's the outstanding shares, we can also calculate the implicit average premium per share: 90,946,000 ÷ 4,652,000 == $19.52. Note that this is the average premium per share, because we don't know when the different stocks were issued at, and it may be that the premiums that investors paid were different. Frankly, we don't care.  So clearly since ""Common Stock"" in 2010 is up to $9,303 it means that the company released more stock. Someone else can chime in on whether that means it was specifically a stock split or some other mechanism... it doesn't matter. For understanding this you just need to know that the company put more stock into the marketplace... 9,303 - 4,652 == 4,651(,000) more shares to be exact. With the mechanics of rounding to the thousands, I would guess this was a stock split.  Now. What you can also see is that the Capital Surplus also increased. 232,801 - 90,946 == 141,855. The 4,651,000 shares were issued into the market at an average premium of 141,855 ÷ 4,651 == $30.50. So investors probably paid (or were given by the company) an average of $31.50 at this split.  Then, in 2011 the company had another small adjustment to its shares outstanding. (The Common Stock went up). And there was a corresponding increase in its Capital Surplus.  Without details around the actual stock volumes, it's hard to get more exact. You're also only giving us a portion of the Balance Sheet for your company, so it's hard to go into too much more detail. Hopefully this answers your question though." First: the question is irrelevant for purchases on exchange, mostly. Majority of sales on stock exchanges is between shareholders. If however you buy directly from the company (in a IPO, or direct share purchase program of some kind, like ESPP), then it does end up showing in the company account ledgers one way or another. It then become part of company's total assets, and the newly sold shares add to the equity. "Most companies get taken over eventually. More to the point, ANY company with a public float over 50 percent that's large and viable enough to fall on people's radar screens will get taken over if its stock price is ""too low"" relative to its long term prospects.  It is the possibility of a takeover, as much as anything else, that bolsters the stock prices of many companies, particularly those that don't pay dividends. In essence, the takeover price is just one large liquidating ""dividend.""" Yes, that is correct. There is no limit.  An initial public offering of common stock by a company means that these shares remain outstanding for as long as the company wishes. The exceptions are through corporate actions, most commonly either You are right that Facebook really doesn't get impacted as they got their $38. However it would make it slightly more difficult for Facebook to raise more money in future as large investors would be more cautious. This can keep the price lowers than it actually needs to be. Quite a few companies try to list the IPO at lower price so that it keeps going up and have more positive effect overall there by making it easier for future borrowings. See related question Why would a company care about the price of its own shares in the stock market? "There is a legal document called a ""Stock Purchase Agreement"" and it depends on who is the other party to the buyer in the Agreement. In almost all startups the sale goes through the company, so the company keeps the money. In your example, the company would be worth $10,000 ""Post-Money"" because the $1k got 10% of the Company." As far as I know, the AMT implications are the same for a privately held company as for one that is publicly traded.  When I was given my ISO package, it came with a big package of articles on AMT to encourage me to exercise as close to the strike price as possible.  Remember that the further the actual price at the time of purchase is from the strike price, the more the likely liability for AMT.  That is an argument for buying early.  Your company should have a common metric for determining the price of the stock that is vetted by outside sources and stable from year to year that is used in a similar way to the publicly traded value when determining AMT liability. During acquisitions stock options often, from what I know of my industry, at least, become options in the new company's stock.  This won't always happen, but its possible that your options will simply translate.  This can be valuable, because the price of stock during acquisition may triple or quadruple (unless the acquisition is helping out a very troubled company). As long as you are confident that the company will one day be acquired rather than fold and you are able to hold the stock until that one day comes, or you'll be able to sell it back at a likely gain, other than tying up the money I don't see much of a downside to investing now. "I think the first misconception to clear up is that you are implying the price of a stock is set by a specific person. It is not. The price of a stock is equal to the value that someone most recently traded at. If Apple last traded at $100/share, then Apple shares are worth $100. If good news about Apple hits the market and people holding the shares ask for more money, and the most recent trade becomes $105, then that is now what Apple shares are worth. Remember that generally speaking, the company itself does not sell you its shares - instead, some other investor sells you shares they already own. When a company sells you shares, it is called a 'public offering'. To get to your actual question, saying something is 'priced in' implies that the 'market' (that is, investors who are buying and selling shares in the company) has already considered the impacts of that something. For example, if you open up your newspaper and read an article about IBM inventing a new type of computer chip, you might want to invest in IBM. But, the rest of the market has also heard the news. So everyone else has already traded IBM assuming that this new chip would be made. That means when you buy, even if sales later go up because of the new chip, those sales were already considered by the person who chose the price to sell you the shares at. One principle of the stock market (not agreed to by all) is called market efficiency. Generally, if there were perfect market efficiency, then every piece of public information about a company would be perfectly integrated into its stock price. In such a scenario, the only way to get real value when buying a company would be to have secret information of some sort. It would mean that everyone's collective best-guess about what will happen to the company has been ""priced-in"" to the most recent share trade." The price of a share of a mutual fund is its Net Asset Value (nav). Before the payout of dividends and capital gain distribution, the fund was holding both stock shares and cash that resulted from dividends and capital gains. After the payout, a share only holds the stock. Therefore once the cash is paid out the NAV must drop by the same amount as was paid out per share. Thus of course assumes no other activity or valuation changes of the underlying assets. Regular market activity will obscure what the payout does to the NAV. "The offering price is what the company will raise by selling the shares at that price.  However, this isn't usually what the general public sees as often there will be shows to drive up demand so that there will be buyers for the stock.  That demand is what you see on the first day when the general public can start buying the stock.  If one is an employee, relative or friend of someone that is offered, ""Friends and Family"" shares they may be able to buy at the offering price. Pricing of IPO from Wikipedia states around the idea of pricing: A company planning an IPO typically appoints a lead manager, known as   a bookrunner, to help it arrive at an appropriate price at which the   shares should be issued. There are two primary ways in which the price   of an IPO can be determined. Either the company, with the help of its   lead managers, fixes a price (""fixed price method""), or the price can   be determined through analysis of confidential investor demand data   compiled by the bookrunner (""book building""). Historically, some IPOs both globally and in the United States have   been underpriced. The effect of ""initial underpricing"" an IPO is to   generate additional interest in the stock when it first becomes   publicly traded. Flipping, or quickly selling shares for a profit, can   lead to significant gains for investors who have been allocated shares   of the IPO at the offering price. However, underpricing an IPO results   in lost potential capital for the issuer. One extreme example is   theglobe.com IPO which helped fuel the IPO ""mania"" of the late 90's   internet era. Underwritten by Bear Stearns on November 13, 1998, the   IPO was priced at $9 per share. The share price quickly increased   1000% after the opening of trading, to a high of $97. Selling pressure   from institutional flipping eventually drove the stock back down, and   it closed the day at $63. Although the company did raise about $30   million from the offering it is estimated that with the level of   demand for the offering and the volume of trading that took place the   company might have left upwards of $200 million on the table. The danger of overpricing is also an important consideration. If a   stock is offered to the public at a higher price than the market will   pay, the underwriters may have trouble meeting their commitments to   sell shares. Even if they sell all of the issued shares, the stock may   fall in value on the first day of trading. If so, the stock may lose   its marketability and hence even more of its value. This could result   in losses for investors, many of whom being the most favored clients   of the underwriters. Perhaps the best known example of this is the   Facebook IPO in 2012. Underwriters, therefore, take many factors into consideration when   pricing an IPO, and attempt to reach an offering price that is low   enough to stimulate interest in the stock, but high enough to raise an   adequate amount of capital for the company. The process of determining   an optimal price usually involves the underwriters (""syndicate"")   arranging share purchase commitments from leading institutional   investors. Some researchers (e.g. Geoffrey C., and C. Swift, 2009) believe that   the underpricing of IPOs is less a deliberate act on the part of   issuers and/or underwriters, than the result of an over-reaction on   the part of investors (Friesen & Swift, 2009). One potential method   for determining underpricing is through the use of IPO Underpricing   Algorithms. This may be useful for seeing the difference in that ""theglobe.com"" example where the offering price is $9/share yet the stock traded much higher than that initially." "A company whose stock is available for sale to the public is called a publicly-held or publicly-traded company.  A public company's stock is sold on a stock exchange, and anyone with money can buy shares through a stock broker. This contrasts with a privately-held company, in which the shares are not traded on a stock exchange. In order to invest in a private company, you would need to talk directly to the current owners of the company. Finding out if a company is public or private is fairly easy.  One way to check this is to look at the Wikipedia page for the company.  For example, if you take a look at the Apple page, on the right sidebar you'll see ""Type: Public"", followed by the stock exchange ticker symbol ""AAPL"".  Compare this to the page for Mars, Inc.; on that page, you'll see ""Type: Private"", and no stock ticker symbol listed. Another way to tell: If you can find a quote for a share price on a financial site (such as Google Finance or Yahoo Finance), you can buy the stock.  You won't find a stock price for Mars, Inc. anywhere, because the stock is not publicly traded." "When you buy a share of stock, you are almost always buying from someone who previously purchased that share and now wants to sell it. The money -- minus broker's fee -- goes to that other investor, which may be a person, a company (rarely the company that issued the stock, but that will occasionally be the case), an investment fund, the ""market maker"" for that stock (websearch for definition of that term), or anyone else. They owned a small percentage of the company; you bought it from them and gave them the money for it, just as you would buy anything else. You don't know or care who you bought from; they don't know or care who they sold to; the market just found a buyer and seller who could agree on the price. There are a very few exceptions to that. The company may repurchase some of its own shares and/or sell them again, depending on its own financial needs and obligations. For example, my own employer has to purchase its own shares periodically so it has enough on hand to sell to employees at a slight discount  through the Employee Stock Ownership Program. But you generally don't know that's who you're selling to; it happens like any other transaction. And during the Initial Public Offering, if you're lucky/privileged enough to get in on the first wave of purchases, you're buying from the investment bank that's managing this process ... though that's an almost vanishingly rare case for ""retail"" investors like us; we're more likely to get the shares after someone has already pushed the price up a bit. But really, when you buy a share the money goes to whoever you bought it from, and that's all you can know or need to know." I would imagine that as a holder you will receive information in the post when it's made public, but I don't think it's been decided yet. This thread on the Motley Fool boards is keeping an eye on them - you might want to keep an eye on the thread. Theoretically, when a company issues more shares, it does not affect the value of your shares.  The reason is that when a company issues and sells more shares, the proceeds from the sale of those shares goes back into the company. Using your example, you have 10 out of 100 shares of the company, for a 10% stake.  Let's say that the shares are valued at $1,000 each, meaning that the market value of the company is $100,000, and your stake is worth $10,000. Now the company issues 100 more shares at $1,000 each.  The company receives $100,000 from new investors, and now the company is worth $200,000.  Your stake is now only 5% of the company, but it is still worth $10,000. The authorized share capital is the amount of shares that a company has already planned on selling.  When you buy stock in a company, you can look up how many shares exist, so you know what your percent stake in the company is.  When a company wants to sell more shares, this is called an increase of authorized share capital.  In order to do this, the company generally needs the approval of a majority of the existing shareholders.
