A Beneficial Owner is an individual who either directly or indirectly: (1) exercises substantial control over the Company, or (2) owns or controls at least twenty-five (25%) percent of the Company’s ownership interests.
Substantial control means senior officers or managers, as well as those individuals who have significant authority or are an important decision-makers within the Company. There is a catch-all in the statute and as identified by FinCEN, so if you're not sure, it's better to assume an individual is an important decision-maker.
An ownership interest means equity, stock, voting rights, capital or profit interest, as well as convertible instruments, options and privileges. Again, there is a catch-all in the statute and as identified by FinCEN, so if you're not sure, it's better to assume an individual does maintain an ownership interest.
This is a very complicated area of the law, is brand new with little-to-no court precedence, and carries significant financial penalties (up to $500/day) and criminal sanctions (i.e. jail time). Our recommendation is to be conservative in your thinking, don't make too many assumptions, and over time, the law will settle and you can dial-back what these terms mean as appropriate.
If you debate any of this, have questions, or just aren't sure, we strongly recommend a 30-minute BOI Attorney Consult.
