| (2) | Ownership Interest represents Denison’s percentage ownership / voting interest in the entity or contractual arrangement;
| (3) | Participating interest represents Denison’s percentage funding contribution to the particular joint operation arrangement. This percentage can differ from voting interest in instances where other parties to the arrangement have carried interests in the arrangement and / or are earning-in or diluting their voting interest in the arrangement; and

WLUC and WLULP were acquired by Denison as part of the Fission Energy Corp acquisition in April 2013. Denison uses its voting interest to account for its share of assets, liabilities, revenues and expenses for these joint operations. In 2017, Denison funded 100% of the activities in these joint operations pursuant to the terms of an agreement that allows it to approve spending for the WLULP without having the required 75% of the voting interest (see note 24).
