Contract assets were $957 million, $690 million and $1,004 million and contract liabilities were $405 million, $500 million and $495 million, at September 30, 2025, December 31, 2024, and September 30, 2024, respectively. The Company recognized revenue of $382 million and $382 million for the nine months ended September 30, 2025, and September 30, 2024, respectively, which was previously included in the contract liability balance at December 31, 2024, and December 31, 2023, respectively.
Contract assets include unbilled revenue and retentions held by customers in respect of construction contracts at September 30, 2025, December 31, 2024, and September 30, 2024 amounting to $697 million and $260 million, $450 million and $240 million, and $752 million and $252 million, respectively. Unbilled revenue represents the estimated value of unbilled work for projects with performance obligations recognized over time. Retentions represent amounts that have been billed to customers but payment is withheld until final acceptance of the performance obligation by the customer. Retentions that have been billed, but are not due until completion of performance and acceptance by customers, are generally expected to be collected within one year. The Company applies the practical expedient and does not adjust any of its transaction prices for the time value of money.
On September 30, 2025, the Company had $3,592 million of transaction price allocated to remaining performance obligations. The majority of open contracts at September 30, 2025 are expected to close and revenue to be recognized within 12 months of the balance sheet date.
