Remaining performance obligations represent the aggregate transaction price allocated to a promise to transfer a good or service that is fully or partially unsatisfied at the end of the period. As of June 30, 2022, remaining performance obligations were approximately $2,082.3 million. The Company expects to recognize revenue on approximately 76% of the remaining performance obligations over the next twelve months and the remaining performance obligations primarily within one to three years.

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 generally classified as other current assets in the unaudited condensed consolidated balance sheets. The balance of contract assets as of June 30, 2022 and December 31, 2021 was $55.2 million and $46.1 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, 2022 and December 31, 2021, the contract liabilities were $434.1 million and $430.8 million, respectively. The increase in the contract liability balance during the six months ended June 30, 2022 is the result of new performance obligations entered into during the period and delays in certain instrument shipments due to supply chain and logistics challenges. Approximately $210.4 million of the contract liability balance on December 31, 2021 was recognized as revenue during the six months ended June 30, 2022.
