⁽¹⁾ Other non-regulated revenue primarily includes lease and derivative revenue not accounted for under ASC 606.

Contract Balances — The timing of revenue recognition, billings, and cash collections results in accounts receivable and contract liabilities. The contract liabilities from contracts with customers were $137 million and $117 million as of June 30, 2020 and December 31, 2019, respectively.

During the six months ended June 30, 2020 and 2019, we recognized revenue of $11 million and $7 million, respectively, that was included in the corresponding contract liability balance at the beginning of the periods.

A significant financing arrangement exists for our Mong Duong plant in Vietnam. The plant was constructed under a build, operate, and transfer contract and will be transferred to the Vietnamese government after the completion of a 25 year PPA. The performance obligation to construct the facility was substantially completed in 2015. Approximately $1.4 billion of contract consideration related to the construction, but not yet collected through the 25 year PPA, was reflected as a loan receivable, net of CECL reserve of $33 million, as of June 30, 2020.

Remaining Performance Obligations — The transaction price allocated to remaining performance obligations represents future consideration for unsatisfied (or partially unsatisfied) performance obligations at the end of the reporting period. As of June 30, 2020, the aggregate amount of transaction price allocated to remaining performance obligations was $12 million, primarily consisting of fixed consideration for the sale of renewable energy credits (“RECs”) in long-term contracts in the U.S. We expect to recognize revenue on approximately one-fifth of the remaining performance obligations in 2020 and 2021, with the remainder recognized thereafter.
