I know mine was paid on the 13th, and I'm pretty sure the rest of the world got theirs on the 13th as well, BUT, who knows, maybe they paid you on the 14th. I'd be willing to bet yours was paid on the 13th as well, but it didn't show in your brokerage acct. until the following day. JMO, but I've been wrong before.
BTW, please supply a link to the rumored quarterly dividend payment change, as YOU are the first one that I have heard this from. That kind of change is very unusual, as it would cost the company a great deal of money to make a quarterly payment.
Thanks in advance for the link from the company stating this intention.
