Rarely, but quite consistently I come across the situation when the payable date precedes the ex-dividend date. A couple of examples: http://www.cboe.com/publish/TTStockSM/05-421.pdf http://www.cboe.com/publish/TTStockSM/05-422.pdf
What does it mean? How's that possible? Notice that in these situations the stock reacts on the Payable date, not on ex-dividend date, as normally would be the case
