Just looking at the recent SH activity and found that 99.42% of the shares are held by top 4 SH. Any body has any idea if this is correct? The CommSec shows the following SH:

1. HSBC Custody Nominees (Australia) Limited = 46.03%
2. Energy World International Ltd = 37.35%
3. JP Morgan Nominees Australia Limited = 8.87%
4. The Capital Group Companies, Inc = 7.17%
---------------------------------------------------------------------------
TOTAL = 99.42%

This left ~10M Shares to be traded if the top 4 are not selling, and this may be the reason we see very little volume traded during normal days (with few days exception recently). Is my calculations correct?
