Aandt is correct. There are 3 or 4 important things to keep in mind.
1) For dividends > 25% of the company value, the ex-date will be delayed until one day after the pay-date. This is a strict rule that all the exchanges have to follow including FINRA on OTC.
2) The ex-date determines who qualifies for the dividend. You have to hold until the ex-date in order to qualify.
3) FINRA will announce the dividend on the FINRA daily list. They will also announce the ex-date which is leading. (This could happen at any time, even past the pay-date).
(4) Best not to trade. There is always another exception to the rule. Simply wait for the dividend to end up in your account.
