Milestones are contractually agreed with customers and relate to significant events across the contract lives. Some milestones are achieved before revenue is recognized, resulting in a contract liability, while other milestones are achieved after revenue is recognized, resulting in a contract asset. The following table provides information about contract assets and contract liabilities from contracts with customers. Six months ended (in thousands) Jun 30, 2024 Jun 30, 2023 Total contract assets, beginning of period $ 234,505 $ 184,847 Revenue accrued 1,167,835 1,077,338 Amounts billed (1,177,865) (1,047,179) Total contract assets, end of period $ 224,475 $ 215,006 Total contract liabilities, beginning of period $ 164,631 $ 112,950 Deferrals of milestone payments 116,619 65,465 Recognition of revenue for goods and services (100,193) (59,394) Total contract liabilities, end of period $ 181,057 $ 119,021 Performance Obligations As of June 30, 2024, the aggregate amount of the transaction price allocated to remaining performance obligations that were unsatisfied (or partially unsatisfied) was $572 million. In arriving at this value, we have used two expedients available to us and are not disclosing amounts in relation to performance obligations: (1) that are part of contracts with an original expected duration of one year or less; or (2) on contracts where we recognize revenue in line with the billing. Of this amount, we expect to recognize revenue of $299 million over the next 12 months, $186 million within the next 24 months, $67 million within the next 36 months, and we expect to recognize substantially all of the remaining balance of $20 million within the next 48 months. In our Manufactured Products and ADTech segments, we have long-term contracts that extend beyond one year, and these make up the majority of the performance obligations balance reported as of June 30, 2024. We also have shorter-term product contracts with an expected original duration of one year or less that have been excluded. Where appropriate, we have made estimates within the transaction price of elements of variable consideration within the contracts and constrained those amounts to a level where we consider it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The amount of revenue recognized in the three- and six-month periods ended June 30, 2024 and 2023, that was associated with performance obligations completed or partially completed in prior periods was not significant. As of June 30, 2024, there were no significant outstanding liability balances for refunds or returns due to the nature of our contracts and the services and products we provide. Our warranties are limited to assurance warranties that are of a standard length and are not considered to be material rights . The majority of our contracts consist of a single performance obligation. When there are multiple obligations, we look for observable evidence of stand-alone selling prices on which to base the allocation. This involves judgment as to the appropriateness of the observable evidence relating to the facts and circumstances of the contract. If we do not have observable evidence, we estimate stand-alone selling prices by taking a cost-plus-margin approach, using typical margins from the type of product or service, customer and regional geography involved. Costs to Obtain or Fulfill a Contract In line with the available practical expedient, we capitalize incremental costs to obtain a contract that would not have been incurred if the contract had not been obtained when those amounts are significant and the contract is expected at inception to exceed one year in duration. Our costs to obtain a contract primarily consist of bid and proposal costs, which are generally expensed in the period when incurred. There were no balances or amortization of costs to obtain a contract in the current reporting periods. Costs to fulfill a contract primarily consist of certain mobilization costs incurred to provide services or products to our customers. These costs are deferred and amortized over the period of contract performance. The closing balance of costs to fulfill a contract was $6.0 million and $7.8 million as of June 30, 2024 and December 31, 2023, respectively. For the three- and six-month periods ended June 30, 2024, we recorded amortization expense of $1.1 million and |
