Revenues And Gross Profit [Abstract]

Revenues and Gross Profit

11.Revenues and Gross Profit

The following tables, which are reconciled to consolidated amounts, provide revenues and gross profit (loss) by line of business: Building Materials (further divided by product line) and Magnesia Specialties. Interproduct revenues represent sales from the aggregates product line to the cement and ready mixed concrete and asphalt and paving product lines. Effective January 1, 2024, the Company combined the cement and ready mixed concrete product lines. This change was driven by the reduced significance of each of these product lines relative to the Building Materials business and consolidated operating results from recent divestitures. Additionally, there is a significant relationship between these product lines, as the ready mixed concrete product line is a significant customer of the cement product line. Revenues and gross profit (loss) reflect continuing operations only.

Performance Obligations. Performance obligations are contractual promises to transfer or provide a distinct good or service for a stated price. The Company’s product sales agreements are single-performance obligations that are satisfied at a point in time. Performance obligations within paving service agreements are satisfied over time, primarily ranging from one day to two years. Customer payments for the paving operations are based on a contractual billing schedule and are typically "paid-when-paid", meaning the Company is paid once the customer is paid.

Future revenues from unsatisfied performance obligations at September 30, 2024 and 2023 were $322 million and $268 million, respectively, where the remaining periods to complete these obligations ranged from one month to 21 months and one month to 25 months, respectively.

Service Revenues. Service revenues, which include paving services located in California and Colorado, were $164 million and $173 million for the three months ended September 30, 2024 and 2023, respectively, and reported in the West Group. Service revenues were $307 million for both the nine months ended September 30, 2024 and 2023.

Contract Balances. Costs in excess of billings relate to the conditional right to consideration for completed contractual performance and are contract assets on the consolidated balance sheets. Costs in excess of billings are reclassified to accounts receivable when the right to consideration becomes unconditional. Billings in excess of costs relate to customers invoiced in advance of contractual performance and are contract liabilities on the consolidated balance sheets. The following table presents information about the Company’s contract balances:

	September 30, 2024		December 31, 2023
	(Dollars in Millions)
Costs in excess of billings	$	26	$	5
Billings in excess of costs	$	17	$	10

Revenues recognized from the beginning balance of contract liabilities for the three months ended September 30, 2024 and 2023 were $7 million and $5 million, respectively, and for the nine months ended September 30, 2024 and 2023 were $9 million and $10 million, respectively.

Retainage, which primarily relates to the paving services, represents amounts that have been billed to customers but payment is withheld until final acceptance of the performance obligation by the customer. Retainage, which is included in Other current assets on the Company’s consolidated balance sheets, was $15 million and $17 million at September 30, 2024 and December 31, 2023, respectively.
