I believe it can be established from the NOBO list

With that said; one might receive additional restricted shares or a retro active dividend or immediate dividend? I'm not sure how the later would work.
In any case it is a very nice gesture on the part of the company.
I don't believe I will qualify since I have only owned shares of the company the past 60 or so days. I think "long" qualifier may be as someone with 6+ months of ownership. Also believe it could be based on amt of common shares held.
