The timing of revenue recognition, billings and cash collections results in billed accounts receivable, note receivables and unbilled receivables (contract assets) and deferred revenue, customer deposits and billings in excess of revenue recognized (contract liabilities) on the Company’s unaudited condensed consolidated balance sheets.

Contract assets—Most of the Company’s long-term contracts are billed as work progresses in accordance with the contract terms and conditions, either at periodic intervals or upon achievement of certain milestones. Billing often occurs subsequent to revenue recognition, resulting in contract assets. Contract assets are classified as either other current assets or other long-term assets in the unaudited condensed consolidated balance sheets. The balance of contract assets as of September 30, 2023 and December 31, 2022 was $90.0 million and $61.3 million, respectively.

Contract liabilities—The Company often receives cash payments from customers in advance of the Company’s performance, resulting in contract liabilities. These contract liabilities are classified as either current or long-term in the unaudited condensed consolidated balance sheets based on the timing of when revenue recognition is expected. As of September 30, 2023 and December 31, 2022, the contract liabilities were $475.4 million and $471.7 million, respectively. Approximately $304.9 million of the contract liability balance on December 31, 2022 was recognized as revenue during the nine months ended September 30, 2023.
