Thanks for letting us know. I suspected the 19th would be the cut off since ex dividend essentially means "without dividend." All the different information out there makes it very confusing. It's good to know for future reference.
The SEC says the ex date on stock dividend is the day after the pay date but they clearly posted it as the 20th. I still wonder if there is possibility that the shares you bought on the 20th will show up later.
Please tell me buys on the 18th get the REGEN shares. Otherwise I am going to be in deep sh%% with my good friends. I told them the 18th was good to buy and get the bonus
