Off-budget enterprise
Off-budget enterprises (OBEs,  or special districts) are a type of government in the United States, the United Kingdom and the European Union. OBEs use public funds to further public (as in education) or private (as in economic revitalization) interests. Regulated by various state and federal laws, they operate outside the regulations for general-purpose government and public scrutiny, although many states have created oversight authorities of one form or another. They achieve self-funding by usually having taxation authority or fund themselves through fees for services rendered. Some have the ability to raise revenue bonds.
