Prior year amounts have been reclassified to conform with current year presentation. Contract Balances Contract balances were as follows (in thousands): March 31, December 31, Financial Statement Classification 2023 2022 Contract assets Unbilled receivables 35,884 38,307 Contract liabilities Accrued expenses and other current liabilities 7,953 6,402 For the three months ended March 31, 2023 and 2022, we recognized revenue that was previously included in the beginning balance of contract liabilities of $1.4 million and $2.1 million, respectively. Performance Obligations As of March 31, 2023, the aggregate amount of transaction prices allocated to unsatisfied or partially unsatisfied performance obligations was $185 million. The performance obligations expected to be satisfied within one year and greater than one year are 94% and 6%, respectively. We have applied the practical expedient for certain parts sales and MRO services to exclude the amount of remaining performance obligations for (i) contracts with an original expected term of one year or less or (ii) contracts for which we recognize revenue in proportion to the amount we have the right to invoice for services performed. During the three months ended March 31, 2023 and 2022, revenue recognized from performance obligations satisfied in prior periods was not material. |
