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 and revenues from certain instrument rental and reagent agreements 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 June 30, 2024, and December 31, 2023, was $103.6 million and $85.8 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 June 30, 2024 and December 31, 2023, the contract liabilities were $595.8 million and $491.4 million, respectively. The increase in the contract liability balance during the six months ended June 30, 2024, is primarily the result of new cash payments received, which was offset in part by satisfying performance obligations. Approximately $227.7 million of the contract liability balance on December 31, 2023 was recognized as revenue during the six months ended June 30, 2024.
