Your not getting it, there isn't any one individual or a organized group of individuals who control the majority of shares, greater than 51%.
How many shares Otto, Cam, Scott or Dan has doesn't matter as no single shareholder according to Dan has even 10% of the shares and the largest are in the 5% range.
The ability to call a shareholder meeting is 25% of the out standing shares.
So until a group of shareholders calls for a board meeting the company is controlled by the board of directors.
That board now consists of Dan, Otto and Scott. Dan and Otto are working together and now have control of the company as directors. Previously it was Scott and Cam who outvoted Dan.
The board is controls the company until such time the shareholders get together to change that.
Also Dan told you that the above information about no shareholder owning even 10% and that he wasn't comfortable disclosing exact figures as reporting shares counts in required for a non reporting company.
So your only telling part of the information you received from Dan as I asked him about it.
Plain and simple there are 3 board members and any two make a majority. At this time that is Dan and Otto.
