Quasi-corporations are unincorporated enterprises that function as if they were corporations. Three main kinds of quasi-corporations are recognised by SNA93, namely: an unincorporated enterprise owned by government units engaged in market production and operated in a similar way to publicly owned corporations; unincorporated enterprises, including unincorporated partnerships, owned by households, which are operated as if they were privately owned corporations; and unincorporated enterprises which belong to institutional units resident abroad such as permanent branches, or offices of production units belonging to foreign enterprises which engage in significant amounts of production over long, or indefinite, periods of time.
