Revenue [abstract]
Revenue	18. Revenue Cameco’s sales contracts with customers contain both fixed and market-related pricing. Fixed-price contracts are typically based on a term-price indicator at the time the contract is accepted and escalated over the term of the contract. Market-related contracts are based on either the spot price or long-term price, and the price is quoted at the time of delivery rather than at the time the contract is accepted. These contracts often include a floor and/or ceiling prices, which are usually escalated over the term of the contract. Escalation is generally based on a consumer price index. The Company’s contracts contain either one of these pricing mechanisms or a combination of the two. There is no variable consideration in the contracts and therefore no revenue is considered constrained at the time of delivery. Cameco expenses the incremental costs of obtaining a contract as incurred as the amortization period is less than a year. The following table summarizes Cameco’s sales disaggregated by geographical region and contract type and includes a reconciliation to the Company’s reportable segments (note 29): For the year ended December 31, 2022 Uranium Fuel services Other Total Customer geographical region Americas $ 806,915 $ 289,028 $ 20,025 $ 1,115,968 Europe 284,602 52,112 2,769 339,483 Asia 388,629 23,923 - 412,552 $ 1,480,146 $ 365,063 $ 22,794 $ 1,868,003 Contract type Fixed-price $ 478,552 $ 355,479 $ 22,794 $ 856,825 Market-related 1,001,594 9,584 - 1,011,178 $ 1,480,146 $ 365,063 $ 22,794 $ 1,868,003 For the year ended December 31, 2021 Uranium Fuel services Other Total Customer geographical region Americas $ 547,257 $ 287,802 $ 12,769 $ 847,828 Europe 218,879 77,110 2,945 298,934 Asia 288,857 39,365 - 328,222 $ 1,054,993 $ 404,277 $ 15,714 $ 1,474,984 Contract type Fixed-price $ 307,858 $ 384,065 $ 11,421 $ 703,344 Market-related 747,135 20,212 4,293 771,640 $ 1,054,993 $ 404,277 $ 15,714 $ 1,474,984 Deferred sales The following table provides information about contract liabilities (note 15) from contracts with customers: 2022 2021 Beginning of year $ 23,316 $ 14,382 Additions 45,978 16,531 Recognized in revenue (2,463) (7,596) Effect of movements in exchange rates 14 (1) End of year $ 66,845 $ 23,316 Deferred sales primarily relates to advance consideration received from customers for future uranium and conversion deliveries as well as revenue related to the storage of uranium and converted uranium held at Cameco facilities. The revenue related to storage is recognized over time while the revenue related to future uranium and conversion deliveries is expected to be recognized between 2023 and 2030. Cameco recognized a decrease of revenue of $ 194,000 (2021 - increase of revenue of $ 383,000 ) during 2022 from performance obligations satisfied (or partially satisfied) in previous periods. This is due to the difference between actual pricing indices and the estimates at the time of invoicing. Future sales commitments Cameco’s sales portfolio consists of short and long-term sales commitments. The contracts can be executed well in advance of a delivery and include both fixed and market-related pricing. The following table summarizes the expected future revenue, by segment, related to only fixed-price contracts with remaining future deliveries as follows: 2023 2024 2025 2026 2027 Thereafter Total Uranium $ 556,122 $ 629,675 $ 627,534 $ 237,052 $ 238,354 $ 622,034 $ 2,910,771 Fuel services 339,355 355,915 329,091 244,236 235,089 1,016,232 2,519,918 Total $ 895,477 $ 985,590 $ 956,625 $ 481,288 $ 473,443 $ 1,638,266 $ 5,430,689 The sales contracts are denominated largely in US dollars and converted from US to Canadian dollars at a rate of $ 1.30 . The amounts in the table represent the consideration the Company will be entitled to receive when it satisfies the remaining performance obligations in the contracts. The amounts include assumptions about volumes for contracts that have volume flexibility. Cameco’s total revenue that will be earned will also include revenue from contracts with market-related pricing. The Company has elected to exclude these amounts from the table as the transaction price will not be known until the time of delivery. Contracts with an original duration of one year or less have been included in the table.
