(1) Ownership Interest represents Denison’s percentage equity / voting interest in the entity or contractual arrangement;

(2) Participating interest represents Denison’s percentage funding contribution to the particular joint operation or contractual arrangement. This percentage can differ from ownership interest in instances where other parties to the arrangement have carried interests, they are earning-in to the arrangement, or they are diluting their interest in the arrangement (provided the arrangement has dilution provisions therein);

(3) Denison Share is where Denison accounts for its share of assets, liabilities, revenues and expenses in accordance with the specific terms within the contractual arrangement. – this can be by using either its ownership interest (i.e. Voting Share) or its participating interest (i.e. Funding Share), depending on the arrangement terms. The Voting Share and Funding Share approaches produce the same accounting result when the Company’s ownership interest and participating interests are equal;

(4) The participating interest for 2020 for these arrangements is shown as Not Applicable as there were no approved spending programs carried out during fiscal 2020.

WLUC and WLULP were acquired by Denison as part of the Fission Energy Corp acquisition in April 2013. Denison uses its equity interest to account for its share of assets, liabilities, revenues and expenses for these joint operations. In 2020, 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 22).
