Given how there are different classes of shares and the rules of ownership regarding aussie rice producers (who hold Class A and Class B) and investors (Class B such as myself), I can see a few pros and cons but won't go into right now until I've done more research.
I thought I'd share this in case others were interested in holding Sunrice but needed to know more about the share structure before deciding.
