I change the questions a little, and enter my guestimates... 1. How many shares do you think the top 10 owners has together? I guess: 5.000.000 shares and 27%. #10 has about 150.000 shares 2. How many shares do you think the top 11-20 owners has together? I guess: 1.000.000 shares and 5-6%. #20 has about 80.000 shares 3. How many shares do you think the top 21-30 owners has together? I guess: 600.000 shares and 3-4%. #30 has about 50.000 shares 3. How many shares do you think it takes to get on the top 100 owners list? I guess: about 30.000 shares 4. How many shareholders do you think there is in total? I guess: about 7.000 share holders This means that top 30 owners has about 35% of the shares. Reasonable?
