Ownership of Uranium
All uranium owned by UPC is stored at licensed uranium conversion, enrichment, or fuel fabrication facilities (each one, a "Facility
" or collectively, the "Facilities
") owned by different organizations in Canada, France, England, Germany, the Netherlands and the United States. The Manager, on behalf of UPC, negotiates storage arrangements with the Facilities. See "Management of UPC". The Facilities represent the only viable source of storage, at present, and are also used by global nuclear energy utilities, and commodity traders for their storage needs. Accordingly, the Corporation's risk in respect of ownership and storage of its uranium is considered largely similar to that of any participant in the nuclear energy industry.
