Doing Business As: denotes a business name used by a person or entity that is different from the person's or entity's true name. DBAs are not separate entities and do not shield the person or entity who uses the DBA as a business name from liability for debts or lawsuits. Filing requirements vary and are not permitted for some types of businesses or professional practices. See also Delaware corporation, Delaware statutory trust, Nevada corporation, and Massachusetts business trust.
Cooperative (aguda shitufit, אגודה שיתופית) – entity which may pursue profit, but with certain legal properties meant to facilitate greater participation by each shareholder, or member, in the entity's affairs. Shareholders usually have an additional relationship with the cooperative, such as employees or consumers. This type of entity is found mainly in agriculture (a kibbutz or moshav is often a cooperative), transportation, or certain types of marketing operations associated with agricultural products. Cooperatives are governed by the Cooperatives Ordinance (פקודת האגודות השיתופיות).
A series LLC is a form of limited liability company that provides liability protection to multiple "series". Essentially, it's a master LLC with separate divisions, each protected and operating independently. As an entity, the series LLC is geared towards businesses where investors own multiple companies, with each series being protected from the debts and obligations of the other series. Currently, only several states support this option, including Delaware, Illinois, Iowa, Nevada, Oklahoma, Puerto Rico, Tennessee, Texas, and Utah.
