Declaration Date: The date on which the board of directors announces to shareholders and the market as a whole that the company will pay a dividend.
Ex Dividend Date
Ex Dividend date: On (or after) this date the security trades without its dividend. If you buy a dividend paying stock one day before the ex-dividend you will still get the dividend, but if you buy on the ex-dividend date, you won't get the dividend. Conversely, if you want to sell a stock and still receive a dividend that has been declared you need to sell on (or after) the ex-dividend day. The ex-date is the second business day before record date or the opening of the market, excluding weekends and holidays. Ex-dividend dates are used to make sure dividend checks go to the right people. In today's market, settlement of stocks is a T+3 process, which means that when you buy a stock, it takes three days from the transaction date (T) for the change to be entered into the company's record books. As mentioned, if you are not in the company's record books on the date of record, you won't receive the dividend payment. To ensure that you are in the record books, you need to buy the stock at least three days before the date of record, which also happens to be the day before the ex-dividend date. Further, for all pending transactions that have not been completed by the ex-dividend date, the exchanges automatically reduce the price of the stock by the amount of the dividend. This is done because a dividend payout automatically reduces the value of the company (it comes from the company's cash reserves), and the investor would have to absorb that reduction in value (because neither the buyer nor the seller are eligible for the dividend).
Record Date
Record date: The date on which the company looks at its records to see who the shareholders of the company are. An investor must be listed as a "holder of record" to ensure the right of a dividend payout.
Payment Date
Payment date: This is the date the company mails out the dividend to the holder of record. This date is generally a week or more after the date of record so that the company has sufficient time to ensure that it accurately pays all those who are entitled.
