What happens to personal data I disclose for joining an employee stock plan?
You aren't getting a straight answer because nobody knows why those regulations are the way they are. Everyone has to give this information to open the brokerage account or for any access to the US financial system whether it is with a bank account, or a brokerage account. Everyone also typically gives this information to their employer to be employed at all for IRS regulations. The SEC isn't going to do anything with the data, unless you do something illegal related to the stock market, then they will know who you are. The IRS isn't going to do anything with the data, unless you are noncompliant in paying taxes, then they will know who you are.
As littleadv says it depends on the local laws.   Normally one shouldn't be too worried. Typically the stocks given to the employees are a very small portion of the overall stocks ... the owners would not try to jeopardize the deal just so that they make an incrementally small amount of money ... they would rather play safe than get into such a practice. "It's anonymous/automated. They don't know who you are, just that customer x1a bought y. If your name isnt given to employees ""your"" privacy isnt being volated because the dont know its ""you.""  I imagine the government justifies their intrusions on our digital privacy the same way." There is a possibility of misuse. Hence it should be shared judiciously. Sharing it with large / trusted organization reduces the risk as there would be right process / controls in place. Broadly these days PAN and other details are shared for quite a few transactions, say applying for a Credit Card, Opening Bank Account, Taking a Phone connection etc. In most of the cases the application is filled out and processed by 3rd party rather than the service provider directly.  Creating Fake Employee records is a possibility so is the misuse to create a fake Bank account in your name and transact in that account. Since one cannot totally avoid sharing PAN details to multiple parties... It helps to stay vigilant by monitoring the Form 26AS from the Govt website. Any large cash transactions / additional salary / or other noteworthy transactions are shown here. It would also help to monitor your CIBIL reports that show all the Credit Card and other details under your name. Is there any precedent for companies trading on their own insider information for the benefit of stockholders?  Said another way, if a company were to enter a new market where they were very confident of their ability to steamroll a public competitor, could they use a wholly-owned special-purpose investment vehicle to short that competitor in order to juice the benefit of that move? Probably not. If you were at a small company and asked such a question, you'd get advice and links to erisa or other case law, etc.  it's safe to say that a Fortune 500 company such as IBM is going to have their facts in order, and not going to run afoul of the rules in these cases (vesting rules and takeover of other company).  I was in a company that cancelled its pension program. Those of us with the required years got the option of a lump sum payout, those with less than 5 years had no vested value and got nothing. One month longer employment, in the case of a particular coworker, would have given him a lump sum worth nearly 6 months pay. "It depends on how the program is run. If the company runs the program out of treasury stock (shares that are authorized, but not issued), then there aren't any shares being purchased on the open market.   Because of that, the share price wouldn't be affected.    If you look in your employer's annual report, you will probably find how the program is run and how many shares are issued annually under that program. By comparing that to the daily trading volume of the company's stock you can gauge whether there's any likelihood of the share price being affected by the employee purchases. That is, of course, if shares are being purchased on the open market.  For example, here is Books-A-Million's program, as described in their 2011 annual report: Employee Stock Purchase Plan   The Company maintains an employee stock purchase plan under which shares of the Company’s common stock are reserved   for purchase by employees at 85% of the fair market value of the common stock at the lower of the market value for the   Company’s stock as of the beginning of the fiscal year or the end of the fiscal year. On May 20, 2010, the stockholders of the   Company approved an additional 200,000 shares available for issuance under the plan, bringing the aggregate number of   shares that may be awarded to 600,000. Of the total reserved shares, 391,987, 373,432 and 289,031 shares have been   purchased as of January 29, 2011, January 30, 2010 and January 31, 2009, respectively. This describes an instance of the employee purchase program being run from unissued stock, not open market purchases. From it, we can tell 18,555 shares were issued during the past fiscal year.  As their average daily volume is ~40,000 shares, if the program were run from a single open market purchase, it would have potential to ""move the market"".  One would think, though, that a company running it from open market purchases would spread the purchases over a period of time to avoid running up the price on themselves." The Employee Benefits Security Administration within the US Department of Labor is tasked with keeping track of pension and 401K programs. The even have a website to search for abandoned plans: it helps participants and others find out whether a particular plan is in the process of being, or has been, terminated and the name of the Qualified Termination Administrator (QTA) responsible for the termination.  The Employee Benefits Security Administration discuss all types of details regarding retirement programs. This document What You Should Know About Your Retirement Plan has a lot of details including this: If your former employer has gone out of business, arrangements should   have been made so a plan official remains responsible for the payment   of benefits and other plan business. If you are entitled to benefits   and are unable to contact the plan administrator, contact EBSA   electronically at askebsa.dol.gov or by calling toll free at   1-866-444-3272. There are also EBSA offices spread thought the United States In all fairness, I have turned opportunities from their site into my own personal cash machine, so this is quid pro quo to me. It is my personal rolodex that self updates. I perceive value in the site. Where else can I click a few buttons and find out who I know or have connections to at a given company for business purposes? For free? I'm trying to reconcile this with why I don't mind them yet I dislike facebook so much. Yes, some companies sell personal data on their customers, but it almost always means a bad business due to reputation cost. The Financial Times even made a calculator to demonstrate how much personal information is worth: The sellers get pennies for the info, so that any decent business would earn more staying away from such dubious operations. "Ditto to MD-Tech, but from a more ""philosophical"" point of view: When you buy stock, you own it, just like you own a cell phone or a toaster or a pair of socks that you bought. The difference is that a share of stock means that you own a piece of a corporation. You can't physically take possession of it and put it in your garage, because if all the stock-holders did that, then all the company's assets would be scattered around all the stock-holder's garages and the company couldn't function. Like if you bought a 1/11 share in a football team, you couldn't take one of the football players home and keep him in your closet, because then the team wouldn't be able to function. (I might want to take one of the cheerleaders home, but that's another subject ...) In pre-electronic times, you could get a piece of paper that said, ""XYZ Corporation - 1 share"". You could take physical possession of this piece of paper and put it in your filing cabinet. I'm not sure if you can even get such certificates any more; I haven't seen one in decades. These days it's just recorded electronically. That doesn't mean that you don't own it. It just means that someone else is keeping the records for you. It's like leaving your car in a parking lot. It's still your car. The people who run the parking lot doesn't own it. They are keeping it for you, but just because they have physical possession doesn't make it theirs." Would anything happen if you bring this issue to the attention of the HR department? Everyone in the company who participates in the 401(k) is affected, so you'd think they'd all be interested in switching to a another 401k provider that will make them more money. You're talking about ESPP? For ESPP it makes sense to utilize the most the company allows, i.e.: in your case - 15% of the paycheck (if you can afford deferring that much, I assume you can). When the stocks are purchased, I would sell them immediately, not hold. This way you have ~10% premium as your income (pretty much guaranteed, unless the stock falls significantly on the very same day), and almost no exposure. This sums up to be a nice 1.5% yearly guaranteed bonus, on top of any other compensation. As to keeping the stocks, this depends on how much you believe in your company and expect the stocks to appreciate. Being employed and dependent on the company with your salary, I'd avoid investing in your company, as you're invested in it deeply as it is. "These people are pretty off. Insider trading cases, outside of a tender offer context, require some sort of a breach of duty. It's not simply ""non-public material information"". You have to trade securities in interstate, based on or while in possession of the material non-public information, and in doing so is a breach of duty owed to the company or to the information source.  Now simply saying ""personal info"" about an executive does not tell me much about its materiality. So assuming it passes the materiality test, and assuming you yourself aren't a corporate insider, then the only thing left to discuss is whether or not it is misappropriation. To be misappropriation you need to be breaching some duty owed to your information source. Now this isn't just principal-agent duty, this can extend to friends and family if there is a pattern of keeping confidences. So unless you're this guys brother or doctor there really isn't a strong claim against you." "There is no unique identifier that exists to identify specific shares of a stock. Just like money in the bank, there is no real reason to identify which exact dollar bills belong to me or you, so long as there is a record that I own X bills and I can access them when I want. (Of course, unlike banks, there is still a 1:1 relationship between the amount I should own and the amount they actually hold). If I may reach a bit, the question that I assume you are asking is how are shared actually tracked, transferred, and recorded so that I know for certain that I traded you 20 Microsoft shares yesterday and they are now officially yours, given that it's all digital. While you can technically try and request a physical share certificate, it's very cumbersome to handle and transfer in that form.  Ownership of shares themselves are tracked for brokerage firms (in the case of retail trading, which I assume is the context of this question as we're discussion personal finance). Your broker has a record of how many shares of X, Y, and Z you own, when you bought each share and for how much, and while you are the beneficial owner of record (you get dividends, voting rights, etc.) your brokerage is the one who is ""holding"" the shares. When you buy or sell a stock and you are matched with a counterparty (the process of which is beyond the scope of this question) then a process of settlement comes into play. In the US, settlement takes 3 working days to process, and technically ownership does not transfer until the 3rd day after the trade is made, though things like margin accounts will allow you to effectively act as if you own the shares immediately after a buy/sell order is filled. Settlement in the US is done by a sole source, the Depository Trust & Clearing Corporation (DTCC). This is where retail and institutional trade all go to be sorted, checked and confirmed, and ultimately returned to the safekeeping of their new owners' representatives (your brokerage). Interestingly, the DTCC is also the central custodian for shares both physical and virtual, and that is where the shares of stock ultimately reside." If one has established a liquid emergency fund of 3 to 6 months income as suggested in several places here as well as being recommended by many financial planners then a savings account is a great place to keep that money. All things being equal between the savings and checking account the limited transfers should be a non issue since ideally you won't be using that money and if you need to in an emergency you could move a whole months worth of expenses to checking in one transfer.  The savings account gives you a place to keep the emergency fund segregated from your normal funds. Out of sight, out of mind as it were. A savings account also gives you a place to stash funds intended for short term goals away from normal use funds. One such example I can use is that I am purchasing several plane tickets for various family members to come visit for Christmas. I have those funds set aside in a savings account so they don't interfere with my budgeting of my normal living expenses. While these are just examples and your situation may vary they are both examples of where a savings account would be useful even if it is identical to a checking account.  Edit:  using other types of accounts can also accomplish the same thing. Since we are using the assumption that the checking and savings accounts are identical the benefit of using a savings account is that it is usually inherently linked to the associated checking account without any additional effort on the part of the account holder. Any other account type would require additional effort, however minor, on the part of the account holder to link them in such a way that would make transfers between accounts as easy as possible.
