(a) | Revenues
In the determination of the minimum transaction prices in contracts with customers, amounts are allocated to fulfilling, or the completion of fulfilling, future contracted performance obligations, which are largely in respect of services to be provided over the duration of the contract. The following table sets out our aggregate estimated minimum transaction prices allocated to remaining unfulfilled, or partially unfulfilled, future contracted performance obligations and the timing of when we might expect to recognize the associated revenues; actual amounts could differ from these estimates due to a variety of factors, including the unpredictable nature of: customer behaviour; industry regulation; the economic environments in which we operate; and competitor behaviour. ​

As at December 31 (millions) |  | 2024 |  | 2023
Estimated minimum transaction price allocated to remaining unfulfilled, or partially unfulfilled, performance obligations to be recognized as revenue in a future period 1, 2 | ​ | ​ | ​ | ​ | ​ | ​
During the 12-month period ending one year hence | ​ | $ | 2,408 | ​ | $ | 2,576
During the 12-month period ending two years hence | ​ | ​ | 976 | ​ | ​ | 1,022
Thereafter | ​ | ​ | 116 | ​ | ​ | 107
​ | ​ | $ | 3,500 | ​ | $ | 3,705
​
1 | Excludes constrained variable consideration amounts, amounts arising from contracts originally expected to have a duration of one year or less and, as a permitted practical expedient, amounts arising from contracts that are not affected by revenue recognition timing differences arising from transaction price allocation or from contracts under which we may recognize and bill revenue in an amount that corresponds directly with our completed performance obligations.
2 | IFRS Accounting Standards require the explanation of when we might expect to recognize as revenue the amounts disclosed as the estimated minimum transaction price allocated to remaining unfulfilled, or partially unfulfilled, performance obligations. The estimated amounts disclosed are based upon contractual terms and maturities. Actual minimum transaction price revenues recognized, and the timing thereof, will differ from these estimates primarily due to the frequency with which the actual durations of contracts with customers do not match their contractual maturities.
