My personal opinion- Almost all the people listed on the list are promoters or main owners of the company.Actualy CEO-Chief Executive Officer means Main Executive among officers. One who was long term employee or well experienced person with years of management experience atlast becomes on the toplevel of the company. These all people are owners of the company whom owns major share of the company. CEO actualy need not be shareholder but he is main responsible for the company opeations and should work according to the directions from the Board of directors.He is the main/leading executive of the company employees. These people cannot be considered as actual CEOs.The mentioned type CEOs are most common for US, Europe and western country companies. I think in India such CEOs are less.This is my view.
