INVENTORIES

Centrus holds uranium at licensed locations in the form of natural uranium and as the uranium component of low enriched uranium (“LEU”). Centrus also holds separative work units (“SWU”) as the SWU component of LEU at licensed locations (e.g., fabricators) to meet book transfer requests by customers. Fabricators process LEU into fuel for use in nuclear reactors. Components of inventories follow (in millions):
