Revenue From Contract With Customer [Abstract]

Revenue Recognition

Note B: Revenue Recognition

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. For product revenues and freight revenues, customer payment terms are generally 30 days from invoice date. Customer payments for the paving operations are based on a contractual billing schedule and are due 30 days from invoice date.

Future revenues from unsatisfied performance obligations at December 31, 2021, 2020 and 2019 were $153.9 million, $110.1 million and $136.1 million, respectively, where the remaining periods to complete these obligations ranged from three months to 12 months.

Sales Taxes. The Company is deemed to be an agent when collecting sales taxes from customers.  Sales taxes collected are recorded as liabilities until remitted to taxing authorities and are not reflected in the consolidated statements of earnings as revenues and expenses.

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:

December 31
(in millions)	2021		2020
Costs in excess of billings	$	4.3	$	2.2
Billings in excess of costs	$	7.8	$	14.0

Revenues recognized from the beginning balance of contract liabilities for the years ended December 31, 2021 and 2020 were $13.6 million and $6.9 million, respectively.

Retainage, which primarily relates to the paving services, represents amounts that have been billed to customers but payment withheld until final acceptance of the performance obligation by the customer. Included in Other current assets on the Company’s consolidated balance sheets, retainage was $10.5 million and $10.6 million at December 31, 2021 and 2020, respectively.

Policy Elections. When the Company arranges third-party freight to deliver products to customers, the Company has elected the delivery to be a fulfillment activity rather than a separate performance obligation.  Further, the Company acts as a principal in the delivery arrangements and, as required by the revenue standard, the related revenues and costs are presented gross and are included in the consolidated statements of earnings.
