Ameritrade shows today is the ex-dividend date, therefore you would have to own the shares yesterday, Jan. 8th in order to qualify for the dividend. If you buy today I'm pretty sure you don't get the dividend payout. That's why it sold off today IMO.
I'm thinking the decrease in stock price will make the eventual distribution a higher number of shares. since the dividend is 11.85 it seems it might be making the decision to take it as a stock dividend vs the cash more attractive.
