Insider Ownership Of Motor Oil (Hellas) Corinth Refineries

While the precise definition of an insider can be subjective, almost everyone considers board members to be insiders. Management ultimately answers to the board. However, it is not uncommon for managers to be executive board members, especially if they are a founder or the CEO.

I generally consider insider ownership to be a good thing. However, on some occasions it makes it more difficult for other shareholders to hold the board accountable for decisions.

Our information suggests that Motor Oil (Hellas) Corinth Refineries S.A. insiders own under 1% of the company. We do note, however, it is possible insiders have an indirect interest through a private company or other corporate structure. It is a pretty big company, so it would be possible for board members to own a meaningful interest in the company, without owning much of a proportional interest. In this case, they own around €20m worth of shares (at current prices). It is always good to see at least some insider ownership, but it might be worth checking if those insiders have been selling.
