The Administration for Soviet Property in Austria, or the USIA (Russian: УСИА, Управление советским имуществом в Австрии) was formed in the Soviet zone of Allied-occupied Austria in June 1946 and operated until the withdrawal of Soviet troops in 1955. USIA operated as a de facto state corporation and controlled over four hundred expropriated Austrian factories, transportation and trading companies. USIA assets included formerly independent Austrian companies (ÖAF), factories once owned by German corporations (AEG) and former SS enterprises (DEST). At its peak in 1951 the conglomerate employed around 60 thousand people,[1] or 10% of Austrian industrial labor.[2] USIA was exempt from Austrian tariffs, disregarded Austrian taxation, and could easily trade with Eastern Europe despite the Iron Curtain and Western trade embargoes. The extraterritorial corporation attempted to be self-sufficient and was very weakly integrated with the rest of Austrian economy.[3]
