AMY (later re-designated AMYRZ)) was the symbol for the class A shares of AmReit, Inc., back when these AmnReit shares were still listed and traded. These class A shares are no longer listed and traded, but they are still outstanding and have been receiving quarterly dividends of $0.10 per share.
AMRE is a new class of B shares, which are listed and traded. Per the company's July 27, 2012 Form 8-K, each class B share has the same voting, distribution and liquidation rights as a class A share.
I e-mailed AMREIT's investor relations department about the trading status of class A shares, and today they replied:
"The Class A shares are not publicly traded; they will have an opportunity to exchange shares for Class B shares as explained in a letter being mailed to investors this week."
If you own any class A shares, you should be aware that the company's Form 8-K also states that the class A shares have undergone a 1:2 reverse stock split. I take this to suggest that class A shareholders (like me) will be given the opportunity to obtain a number of class B shares equal to half the number of class A shares they had formerly owned.
Just opened my mail from AmReit and you are 100% correct. We have Class A stock and has undergone a 1 for 2 reverse split. AmReit Class B (AMRE) is now trading at about $14 per share and eventually we will be able to exchange. We can't trade so we must hold until the exchange!
