I own ASPIRO shares (Jay Z's new company). Now that it is going private, what about my shares?
From the press release Based on Aspiro's closing share price of SEK 0.66 as of 29 January   2015, the Offer values each Aspiro share at SEK 1.05 and the total   value of the Offer at approximately SEK 464 million.[3] The Offer   represents a premium of..... It seems you will get cash. I can't explain the pop to 11. You don't have any option to keep the shares.
It's a dilution of the ownership; the public used to own x% of Facebook and now they own less than x% of the bigger Facebook that incorporates Whatsapp (assuming that Whatsapp was completely private before). Logically, the $15 billion is allocated proportionately between the existing stockholders (x% of it for the general public, y% for Mark Zuckerberg, etc).  However it doesn't really make sense to think of it that way unless Whatsapp is actually worthless. What's important are the proportions. Suppose that the newly issued shares correspond to 25% of the previous share capital. Then previously the general public owned x% out of 100%, and now they own x% out of 125%, i.e. (0.8x)% of the new share capital. Whether the actual value of those stocks has changed depends entirely on the actual value that Whatsapp adds to the old Facebook. As Dheer says, only time will tell on that one. Apart from the financial consequences, dilution is sometimes considered important because it can mean a change in influence: a significant shareholder would often be able to encourage the company to act in a certain way. With a lower percentage ownership, that influence is diminished. "I finally found it! Johnson Controls International PLC FORM 8-K/A (Amended Current report filing) Filed 10/03/16 for the Period Ending 09/02/16 from http://investors.johnsoncontrols.com/financial-information/johnson-sec-filings, says on page II-6: (my emphasis for the relevant paragraph) On September 2, 2016, Johnson Controls and Tyco completed their   combination pursuant to the Agreement and Plan of Merger (the “Merger   Agreement”), dated as of January 24, 2016, as amended by Amendment No.   1, dated as of July 1, 2016, by and among Johnson Controls, Tyco and   certain other parties named therein, including Jagara Merger Sub LLC, an   indirect wholly owned subsidiary of Tyco (“Merger Sub”).   Pursuant to the terms of the Merger Agreement, on September 2, 2016,   Merger Sub merged with and into Johnson Controls with Johnson Controls   being the surviving corporation in the merger and a wholly owned,   indirect subsidiary of Tyco (the “merger”).   Following the merger, Tyco changed its name to “Johnson Controls   International plc.”  Immediately prior to the merger and in connection   therewith, Tyco shareholders received 0.955 ordinary shares of Tyco   (which shares are now referred to as “combined company ordinary shares”)   for each Tyco ordinary share they held by virtue of a 0.955-for-one   share consolidation. In the merger, each outstanding share of common   stock, par value $1.00 per share, of Johnson Controls (“Johnson Controls   common stock”) (other than shares held by Johnson Controls, Tyco and   certain of their subsidiaries) was converted into the right to receive   either the cash consideration or the share consideration (each as   described below), at the election of the holder, subject to proration   procedures described in the Merger Agreement and applicable withholding   taxes.   The election to receive the cash consideration was undersubscribed. As a   result, holders of shares of Johnson Controls common stock that elected   to receive the share consideration and holders of shares of Johnson   Controls common stock that made no election (or failed to properly make   an election) became entitled to receive, for each such share of Johnson   Controls common stock, $5.7293 in cash, without interest, and 0.8357   combined company ordinary shares, subject to applicable withholding   taxes.   Holders of shares of Johnson Controls common stock that elected to   receive the cash consideration became entitled to receive, for each such   share of Johnson Controls common stock, $34.88 in cash, without   interest, subject to applicable withholding taxes.   In the merger, Johnson Controls shareholders received, in the aggregate,   approximately $3.864 billion in cash. Immediately after the closing of,   and giving effect to, the merger, former Johnson Controls shareholders   owned approximately 56% of the issued and outstanding combined company   ordinary shares and former Tyco stockholders owned approximately 44% of   the issued and outstanding combined company ordinary shares. This answers what actually happened in the transaction; as far as my cost basis in the new JCI, it's a little more obscure; on page II-7 it says: For pro forma purposes, the valuation of consideration transferred is   based on, amongst other things, the adjusted share price of Johnson   Controls on September 2, 2016 of $47.67 per share and on page II-8: Johnson Controls adjusted share price as of September 2, 2016 (2): $47.67 (2) Amount equals Johnson Control closing share price and market   capitalization at September 2, 2016 ($45.45 and $29,012 million,   respectively) adjusted for the Tyco $3,864 million cash contribution   used to purchase 110.8 million shares of Johnson Controls stock for   $34.88 per share. and both agree with the information posted at http://www.secinfo.com/dpdtb.w6n.2n.htm#1stPage (R66 Merger Transaction Fair Value of Consideration Transferred (Details)) which I can't seem to find on an ""official"" website but it purports to post from the SEC EDGAR database.    So for each share of JCI, it had a fair value of $47.67 prior to the acquisition, and transformed into $5.7293 in cash, plus 0.8357 of ""new"" JCI shares with a basis of $47.67 - $5.7293 = $41.9407. Stated in terms of ""new"" JCI shares, this is $50.1863 (=$41.9407/0.8357) per ""new"" JCI share. (I'm not really 100% sure of this calculation though.)  I also found JCI's Form 8937 which states Fair market value generally is the price at which property would change hands between a willing buyer and a willing seller, neither being under any compulsion to buy or sell and both having reasonable knowledge of the facts. U.S. federal income tax law does not specifically prescribe how former JCI shareholders should determine the fair market value of the Tyco ordinary shares received in the merger.  One possible method of determining the fair market value of one Tyco ordinary share is to use the average of the high and low trading prices on the date of the merger, which was $45.69. Other methods for determining the fair market value of Tyco ordinary shares are possible. Former JCI shareholders are not bound by the approach described above and may, in consultation with their tax advisors, use another approach.   as well as similar text on the IRS website: One possible method of determining the fair market value of one Tyco ordinary share is to use the average of the high and low trading prices on the date of the merger, which was $45.69. Using this figure, former JCI shareholders that elected to receive shares in the merger would receive cash and Tyco ordinary shares worth approximately $43.91 per share of JCI common stock exchanged in the merger (assuming no cash received in lieu of fractional shares)." I do not know for sure so do not quote me on this. But I would assume that you will get paid out to what the value of the buyout is.  Example if your company has 100 private shares and you own 1 share (1%), and the company sells for $1,000,000. Your share will be worth 1% of the $1 million. number of shares is finite Yes it is I would assume that the repurchase numbers exceed the numbers of created shares Number of shares repurchased by company would never exceed in theory the total number of shares. It can become Zero, however its unlikely as it would run on its own and its not possible. In practise company generally repurchase a small percentage say 5% - 10% of the outstanding shares. The number of shares additional created is irrelevant. Its the total shares that is relevant. Edit: A company starts with say 100 shares, over the period it creates new shares [via various mechanisms, Rights issue, split, Additional shares, etc] say to the extent of 50. So now the company has total shares of 150. This lets say is held by 15 entities. The company can buy back say 15 shares in a year, and keep doing this, next year another 10 etc. However a company if it purchased all 150 of its own shares is unlikely as the Majority shareholders will not like this to happen and loose control. There are 2 different things, buying out of minority shareholders, typically different percentage of the shares are held by non-promoters and available for trade can range from 10% to 70% ... there are also listing norms. Quite a few stock-exchange need atleast 10% shares to be available for trade [held by non-promotors]. In case a company has a small number of shares held by non-promoters, it can buy back the shares and delist the company from the exchange. "@Alex B's answer hits most of it, but leaves out one thing: most companies control who can own their non-public shares, and prohibit transfers, sales, or in some cases, even ongoing ownership by ex-employees. So it's not that hard to ensure you stay under 500 investors.   Remember that Sharespost isn't an exchange or clearinghouse; it's basically a bulletin board with some light contract services and third-party escrow services.   I'd guess that many of the companies on their ""hot"" list explicitly prohibit the sale of their non-public shares." You likely received the shares as ordinary income for services of $10k, since they withheld taxes at granting.  Separately, you likely had a short term capital loss on sale of $2k, since your holding period seems to have been under one year. A public company should have a link for investor relations, which should help provide a trail of basis if this is a matter of company buyout, takeover, etc.  This gets you close, but if you don't have an exact date, it will just be close, not exact.  One clean way out of this, assuming the goal is to get rid of the stock and move on, is to donate the shares to charity. You will take the present value as a deduction, and be done. You can use a charitable gift fund such as those offered by Schwab or Fidelity, so if say, the shares are worth $20K, and you typically donate $5K per year, the fund lets you do this transaction at once, then send to the charities you wish over the next few years. Initially, Each company has 10k shares. Company B has $500k money and possibly other assets. Every company has stated purpose. It can't randomly buy shares in some other firm.   Company A issued 5k new shares, which gives it $500k money. Listed companies can't make private placements without regulatory approvals. They have to put this in open market via Public issue or rights issue. Company B does the same thing, issuing 5k shares for $500k money. Company A bought those 5k shares using the $500k it just got There is no logical reason for shareholder of Company B to raise 5K from Company A for the said consideration. This would have to increase.
