Revenue from Contract with Customer [Abstract]

Revenue

Contract Balances with Customers

The balances of receivables from contracts with customers listed in the table below include both current trade receivables and long-term receivables, net of allowance for expected credit losses. The allowance for expected credit losses represents our best estimate of the probable losses associated with potential customer defaults. We estimate the expected credit losses based on historical write-off experience by industry and current expectations of future credit losses.

Costs to Obtain or Fulfill a ContractThe Partnership recognizes an asset from the costs incurred to obtain a contract (e.g. sales commissions) only if it expects to recover those costs. On the other hand, the costs to fulfill a contract are capitalized if the costs are specifically identifiable to a contract, would result in enhancing resources that will be used in satisfying performance obligations in the future, and are expected to be recovered. These capitalized costs are recorded as a part of other current assets and other non-current assets and are amortized as a reduction of revenue on a systematic basis consistent with the pattern of transfer of the goods or services to which such costs relate. The amount of amortization on these capitalized costs that the Partnership recognized was $6 million and $15 million for the three and nine months ended September 30, 2021, respectively, and $4 million and $14 million for the three and nine months ended September 30, 2020, respectively. The Partnership has also made a policy election of expensing the costs to obtain a contract, as and when they are incurred, in cases where the expected amortization period is one year or less.
