Cameco has contractual capital commitments of approximately $47,000,000 at December 31, 2020. Certain of the contractual commitments may contain cancellation clauses, however the Company discloses the commitments based on management’s intent to fulfill the contract. The majority of this amount is expected to be incurred in 2021.

(a) Asset retirement obligation assets are adjusted when the Company updates its reclamation provisions due to new cash flow estimates or changes in discount and inflation rates. When the assets of an operation have been written off due to an impairment, as is the case with our Rabbit Lake operation and some of our operations in the United States, the adjustment is recorded directly to the statement of earnings as other operating expense or income.
