and does not include post-extraction activities, such as refining, processing, marketing, distribution, transportation or export. With the exception of payments
made to Indigenous Payees, the amounts reported are on a 100% basis with no adjustment to reflect the minority ownership interest of other entities in the
commercial development of minerals undertaken by Cameco and its subsidiaries. Payments made to Indigenous Payees in Canada are reported at Cameco’s
share.
