KOO - without totally knowing the structure of EC and just knowing what I do, I would agree that EC should not be considered an Institutional Investor. I don't think they are. If they are, that would mean there are no other Institutional investors or any size to speak of. Try this.
Public Company (SH) 36%
General Public 48% Including EC
Insiders 4%
Institutional 12% not including EC
________________________
Total 100%
Marketwatch states that the public float is 60% which could be the General Public and Institutional.
