67. Adding a 180 day expiration to checks
Your bank has discretion to honor checks after 6 months, so you should talk to your bank about their specific policy. In general, banks won't accept "large" stale checks. The meaning of "large" varies -- $25,000 in NYC, as little as $2k in other places. Banks that service high-volume check issuers (like rebate companies) reject checks at 180 days. For business purposes, I think some banks will create accounts for specific mailings or other purposes as well. (i.e. 2011 refund account) The accounts close after a year.

68. Why might it be advisable to keep student debt vs. paying it off quickly?
Congratulations for achieving an important step in the road to financial freedom. Some view extending loan payment of loans that allow the deduction of interest as a good thing. Some view the hit on the credit score by prematurely paying off an installment loan as a bad thing.  Determining the order of paying off multiple loans in conjunction with the reality of income, required monthly living expense, and the need to save for emergencies is highly individualized.  Keeping an artificial debt seems to make little sense, it is an expensive insurance policy to chase a diminishing tax benefit and boost to a credit score. Keep in mind it is a deduction, not a credit, so how much you save depends on your tax bracket.  It might make sense for somebody to extend the loan out for an extra year or two, but you can't just assume that that advice applies in your situation. Personally I paid off my student loan early, as soon as it made sense based on my income, and my situation. I am glad I did, but for others the opposite made more sense.

69. Can a company block a specific person from buying its stock?
A more serious problem: how do you know who's really buying your stock? "Shell companies" are an increasingly obvious problem in corporate and tax accountability. There are jurisdictions where companies can be created with secret lists of directors and shareholders. If stock is bought by one of these companies, it is very hard to trace it to a particular individual.

70. What are the pros and cons of buying an item on installments with zero percent interest?
I personally take the zero percent financing plans any day.  I have done this with my car and the iphone 6s.  The vendors are trying to make it more attractive for you to "afford" the product.  It could show up on your credit report and impact the amount of money you can borrow in the future (e.g getting a home loan).  The other thing I do is make sure the monthly payments are automatically paid from my bank account so I don't miss any payments

71. why do energy stocks trade at lower prices compared to other sectors?
I don't know why stocks in some industries tend to have lower prices per share than others. It doesn't really matter much. Whether a company has 1,000,0000 shares selling for $100 each, or 10,000,000 shares selling for $10 each, either way the total value is the same. Companies generally like to keep the share price relatively low so that if someone wants to buy a small amount, they can. Like if the price was $10,000 per share, than an investor with less than $10,000 to put in that one stock would be priced out of the market. If it's $10, then if someone wants $10 they can buy one share, and if someone wants $10,000 they can buy 1000 shares. As to why energy stocks are volatile, I can think of several reasons. One, in our current world, energy is highly susceptible to politics. A lot of the world's energy comes from the Middle East, which is a notoriously unstable region. Any time there's conflict there, energy supplies from the region become uncertain. Oil-producing countries may embargo countries that they don't like. A war will, at the very least, interfere with transportation and shipping, and may result in oil wells being destroyed. Etc. Two, energy is consumed when you use it, and most consumers have very limited ability to stockpile. So you're constantly buying the energy you need as you need it. So if demand goes down, it is reflected immediately. Compare this to, say, clothing. Most people expect to keep the same clothes for years, wearing them repeatedly. (Hopefully washing them now and then!) So if for some reason you decided today that you only need three red shirts instead of four, this might not have any immediate impact on your buying. It could be months before you would have bought a new red shirt anyway. There is a tendency for the market to react rather slowly to changes in demand for shirts. But with energy, if you decide you only need to burn 3 gallons of gas per week instead of 4, your consumption goes down immediately, within days. Three, really adding to number two, energy is highly perishable, especially some forms of energy. If a solar power station is capable of producing 10 megawatts but today there is only demand for 9 megawatts, you can't save the unused megawatt for some future time when demand is higher. It's gone. (You can charge a battery with it, but that's pretty limited.) You can pile up coal or store natural gas in a tank until you need it, but you can't save the output of a power plant. Note numbers two and three also apply to food, which is why food production is also very volatile.

72. First Job, should I save or invest?
Congrats on your first real job! Save as much as your can while keeping yourself (relatively) comfortable.  As to where to put your hard earned money, first establish why you want to save the money in the first place. Money is a mean to acquire the things we want or need in your life or the lives of others. Once your goals are set, then follow this order:

73. Why is property investment good if properties de-valuate over time?
One reason for this is that many people don't simply allow their houses to rot and decay. If you're talking about a house built in 1980 and left vacant and unmaintained for 35 years, it probably will be in pretty poor shape.  But a homeowner generally wants to preserve their house and maintain it in good condition, so they invest in things like new roofs, siding, gutters, windows, paint, exterminators, new furnaces, hot water heaters, air conditioners, etc... All this stuff costs money (and for tax purposes, can often be factored into the cost basis of the house when it is sold), but it maintains the value of the property. A small hole in the roof may be fairly cheap to fix, but if left unrepaired, it could eventually cause much of the building to rot, making the structure near worthless. If a car slams into your living room, you don't generally leave it there; most people repair the damage.  It's not uncommon in some areas to have 100 year old houses (or 300+ year old houses in some countries) that were built well in the first place and have been well maintained in the interim.  People also renovate their homes, ripping out outdated construction and appliances and sometimes building new additions, decks, porches, etc... This also serves to make the property more attractive and increases its value.

74. Why are index funds called index funds?
Because they track an index. Edited: The definition of the word in this case meaning "something used or serving to point out; a sign, token, or indication" from Meaning  #3 I presume therefore you are asking what an index is? There are many variations of what makes up an Index but in short it is a representation of some part of a market. An extremely simplistic calculation would be to take a basket of stocks, and sum their prices.  If one stock moves up a dollar, and one moves down a dollar, the index has effectively not changed, as it is presumed that the loss in one is offset by the gain in the other.

75. What does PMI mean?
Private Mortgage Insurance. It's money that you pay to an insurance company to make the lender whole in the event that you go into default. It's a real waste of money for you. If you are trying to finance more than 80% of the value of a home, a standard mortage is likely to require that you get PMI. Nowadays there are other options which involve paying substantially more interest.

76. How to distinguish gift from payment for the service?
Generally, a one time thing is considered a gift. For the donor this is obviously not a deductible expense, except for some specific cases (for example promotional gifts under $25 to vendors can be deducted, if you're a business, or charitable contributions to a recognized charity). However, if this is a regular practice - that would not be considered as a gift, but rather as a tax fraud, a criminal offense. Being attentive I would like to make a little gift or give some little   (<100$) amount of money (cash/wire/online) for that Why? Generally, gift is exempt from income if no services were provided and the gift was made in good faith. In the situation you describe this doesn't hold. When the gift is exempt from income to the receiver - the donor pays the tax (in this case, below exemption the tax is zero). If the gift is not exempt from income to the receiver - it is no longer a gift and the receiver is paying income taxes, not the donor. The situation you describe is a classic tax evasion scheme. If someone does it consistently and regularly (as a receiver, donor, or both) - he would likely end up in jail.

77. Recent college grad. Down payment on a house or car?
Given the state of the economy, and the potential of a rough near future for us recent grads (i.e. on/off work), I would recommend holding off on large purchases while your life is in flux.  This includes both a NEW car and purchasing a house. My short answer is: you need a reliable vehicle, so purchase a used car, from a major dealer (yes this will add a fairly high premium, but easier financing), that is 4-5 years old, or more.  Barring the major dealer purchase, be sure to get a mechanic to check out a vehicle, many will offer this service for a reasonable payment.  As people point out, cars these days will run for another 100k miles.  You will NOT have to pay anywhere near $27,000 for this vehicle.  You may need to leverage your 10k for a loan if you choose to finance, but it should not be a problem, especially as you seem to imply an established credit history. In addition to this, start saving your money for the house you would like to eventually get.  We have no idea where you live, but, picking rough numbers, assuming a 2 year buy period, 20% down, and a $250,000 home, the down payment alone will require you to save ~$2,000/month starting now. Barring either of these options, max out your money to tax sheltered accounts (your Roth IRA, work 401k, or a regular IRA) asap.  Obviously, do not deplete your emergency fund, if anything, increase it.  10k can be burned through in a heartbeat. Long Answer:  I purchased a brand new car, right out of school, at a reasonable interest rate.  Like you, I can afford this vehicle, however, if someone were to come to me today (3.5 years later) and offer me the opportunity to take it back and purchase a 4-5 year used vehicle, at a 4-5 year used car price, albeit at a much higher interest rate (since I financed), it would be about a 0.02 second decision. I like my car, but, I'd like the differential cash savings between it and a reliable used car more.  $27,000 is also fairly expensive for a new vehicle, there are many, very nice vehicles, for 21-23k.  I still would not consider these priced appropriate to spend your money on them, but they exist.  However, you do very much need a reliable vehicle, and I think you should get one. On the home front, your $400 all inclusive rent is insanely cheap.  Many people spend more than that on property tax and PMI each year, so anyone who throws the "You're throwing money away!" line at you is blowing smoke to justify their own home purchase.  Take the money you would have spent on a mortgage, and squirrel it away.  Do your own due diligence and research the home market in your area and decide for yourself if you think home prices have bottomed and will stay there, have further to go, or are going to begin to rise.  That is a decision only you can make for yourself. I'd add a section about getting expenses under control, but you said you could save 50% of your takehome pay.  This is an order of magnitude above the average.  Good job.  Try doing 50% for 4 months, then calculate your actual amount.  Then try to beat it.

78. Comparing keeping old car vs. a new car lease
Look at the basic cost of the lease.  Option 1: keep the car for three years. Pay for repairs during that time then sell it for $7,000. Option 2: Sell the current car for $10,000. Lease a new car for three years. Assume no need for repairs during those three years. At the end of the three years return the car in return for $0. Cost of option 1 is $3000 plus repairs.  Cost of Option 2 is 36 months x monthly lease cost. The first $83 of the monthly lease cost is to cover the $3000 fixed cost of option 1. The rest of the monthly lease cost is to cover the cost of repairs. Also remember that some leases have a initial down payment due at signing, and penalties for condition, and excess mileage. The lease company may also require a higher level of insurance for the lease to cover their investment if you have an accident.  Plus If you fall in love with a different car two year from now, or your needs change you are locked in until the end of the lease period.

79. How does giving to charity work?
For many people, giving to charity will have minimal effect on their taxes. Non-profits love to attract donations by saying the money is tax deductible, but for most people, it doesn't work out that way. You will only itemize deductions if they exceed your standard deduction. The IRS allows you to either "itemize" your deductions (where you list each deduction you can take) or take the "standard deduction". Consider a married couple filing jointly in 2011. Their standard deduction is $11,400. They are in the 28% tax bracket. They donate $100 of old clothes to the Goodwill, and are looking forward to deducting that on your taxes, and getting $28 of that back. If that's their only deduction, though, they'd have to give up the standard deduction to take the itemized deduction. Not worth it. Suppose instead they have $11,500 of deductions in 2011. Now we're talking, right? No. The tax impact of itemizing is only $28, since they only exceeded the standard deduction by $100. The cost of having a tax accountant fill out the itemization form probably offsets that small gain. There's also all the time that went in to tracking those deductions over the year. Not worth it.  Tax deductions only become worthwhile when they significantly exceed the standard deduction. You need some big ticket items to get past the itemized deduction threshold. For most people, this only happens when they have a mortgage, as the interest on a residence is deductible.  Folks love to suggest that having a mortgage is a good deal, because the interest is deductible. However, since you have to exceed the standard deduction before it makes sense to itemize, it's not likely to be a big win. For most people: TL;DR: Give to charity because you want that charity to have your money. Tax implications are minimal; let your accountant sort it out. Disclaimer: I am not an accountant.

80. Why is routing number called ABA/ABN number?
With number of Banks increasing every country at some point in time adopted an Identification code. In US these are called ABA number because they are allocated by American Bankers Association, in UK Sort Codes ... like wise for other countries. See list here http://en.wikipedia.org/wiki/Bank_code In some countries the numbers are given by Central Bank.   To enable internationl payments, the SWIFT body apart from message formats, allocated a  SWIFT BIC [Bank identification Code] so that Banks can be globally identified. Currently  IBAN being adopted in Europe & Australia to identify an Account [at a Bank] Uniquely across globe. In essence these number help uniquely identify a Location/Bank/Branch. The clearing house route the payments or collection instruments to the correct Bank on the basis of this number.

81. How did I end up with a fraction of a share?
Theoretically, yes, you can only buy or sell whole shares (which is why you still have .16 shares in your account; you can't sell that fraction on the open market). This is especially true for voting stock; stock which gives you voting rights in company decisions makes each stock one vote, so effectively whomever controls the majority of one stock gets that vote. However, various stock management policies on the part of the shareholder, brokerage firm or the issuing company can result in you owning fractional shares. Perhaps the most common is a retirement account or other forward-planning account. In such situations, it's the dollar amount that counts; when you deposit money you expect the money to be invested in your chosen mix of mutual funds and other instruments. If the whole-shares rule were absolute, and you wanted to own, for instance, Berkshire Hathaway stock, and you were contributing a few hundred a month, it could take you your entire career of your contributions sitting in a money-market account (essentially earning nothing) before you could buy even one share. You are virtually guaranteed in such situations to end up owning fractions of shares in an investment account. In these situations, it's usually the fund manager's firm that actually holds title to the full share (part of a pool they maintain for exactly this situation), and your fractional ownership percentage is handled purely with accounting; they give you your percentage of the dividends when they're paid out, and marginal additional investments increase your actual holdings of the share until you own the whole thing. If you divest, the firm sells the share of which you owned a fraction (or just holds onto it for the next guy fractionally investing in the stock; no need to pay unnecessary broker fees) and pays you that fraction of the sale price.  Another is dividend reinvestment; the company may indicate that instead of paying a cash dividend, they will pay a stock dividend, or you yourself may indicate to the broker that you want your dividends given to you as shares of stock, which the broker will acquire from the market and place in your account. Other common situations include stock splits that aren't X-for-1. Companies often aren't looking to halve their stock price by offering a two-for-one split; they may think a smaller figure like 50% or even smaller is preferable, to fine tune their stock price (and thus P/E ratio and EPS figures) similar to industry competitors or to companies with similar market capitalization. In such situations they can offer a split that's X-for-Y with X>Y, like a 3-for-2, 5-for-3 or similar. These are relatively uncommon, but they do happen; Home Depot's first stock split, in 1987, was a 3-for-2. Other ratios are rare, and MSFT has only ever been split 2-for-1. So, it's most likely that you ended up with the extra sixth of a share through dividend reinvestment or a broker policy allowing fractional-share investment.

82. Why do financial institutions charge so much to convert currency?
Is there not some central service that tracks current currency rates that banks can use to get currency data? Sure.  But this doesn't matter.  All the central service can tell you is how much the rate was historically.  But the banks/PayPal don't care about the historical value.  They want to know the price that they'll pay when they get around to switching, not the last price before the switch.  Beyond that, there is a transaction cost to switching.  They have to pay the clearinghouse for managing the transaction.   The banks can choose to act as a clearinghouse, but that increases their risk.  If the bank has a large balance of US dollars but dollars are falling, then they end up eating that cost.  They'll only take that risk if they think that they'll make more money that way.  And in the end, they may have to go on the currency market anyway.  If a European bank runs out of US dollars, they have to buy them on the open market.  Or a US bank might run out of Euros.  Or Yen.  Etc.   Another problem is that many of the currency transactions are small, but the overhead is fixed.  If the bank has to pay $5 for every currency transaction, they won't even break even charging 3% on a $100 transaction.  So they delay the actual transaction so that they can make more than one at a time.  But then they have the risk that the currency value might change in the meantime.  If they credit you with $97 in your account ($100 minus the 3% fee) but the price actually drops from $100 to $99, they're out the $1.   They could do it the other way as well.  You ask for a $100 transaction.  They perform a $1000 transaction, of which they give you $97.  Now they have $898 ($1000 minus the $5 they paid for the transaction plus the $3 they charged you for the transaction).  If there's a 1% drop, they're out $10.98 ($8.98 in currency loss plus a net $2 in fees).   This is why banks have money market accounts.  So they have someone to manage these problems working twenty-four hours a day.  But then they have to pay interest on those accounts, further eating into their profits.  Along with paying a staff to monitor the currency markets and things that may affect them.

83. Is it a good investment for a foreigner to purchase a flat/apartment in China?
I think a greater problem would be the protection of your property right.  China hasn't shown much respect for the property rights of its own citizens - moving people off subsistence farms in order to build high-rise apartments - so I'm not certain that a foreigner could expect much protection.  A first consideration in any asset purchase should always be consideration of the strength of local property law.  By all accounts, China fails.
