Stiftung
German, *noun*: "foundation"; a type of business organization dating from the late 19th century in which one or more companies are owned by a foundation. The foundation, in turn, is governed not by shareholders, but by whomever is chartered as a stakeholder in the firm, such as workers, financial planners, local residents of the town where the firm operates, and so on.
The biggest company owned by a foundation is Robert Bosch GmBH, which is 92% owned by Robert Bosch Stiftung (Stuttgart, Germany). Bertelsmann AG (Guetersloh, Germany) is owned by the Bertelsmann-Stiftung, which appears to possess the largest endowment of any German foundation; the affiliated company owns an enormous media empire.
Plural: Stiftungen
