An LLC may be established by one or more persons or legal entities (the “participants”).
However, if the number of participants exceeds 50, the entity must be reorganized into an open joint stock company or a production cooperative within one year.
Furthermore, an LLC may not have as its sole participant another business entity consisting of a single person. The charter capital of the LLC is divided into participation interests held by its participants, as set forth in the charter.
