The law distinguishes between several company types by the nature of capital and the limits of liability.
Joint-stock company: its capital is divided into tradable shares of equal value, and a shareholder's liability is limited to paying the value of the shares subscribed; the shareholder is not liable for the company's debts except within that amount (art. 2). It has a trade name derived from its purpose (art. 2).
Limited liability company (LLC): the number of partners may not exceed fifty, and each is liable only to the extent of their share (art. 4). It may not be established, increase its capital, or borrow through public subscription, and may not issue tradable shares or bonds (art. 4).
There is also the partnership limited by shares, whose capital consists of a stake held by one or more joint (unlimited) partners plus shares of equal value; the joint partner bears unlimited liability, while the shareholding partner is liable only up to the value of their shares (art. 3). Finally, the number of founders may not be fewer than three in joint-stock companies and not fewer than two in the other companies (art. 8).
